Definitions
- the present invention relates generally to flexible packaging and, more particularly, to flexible packaging having at least one segregated internal compartment capable of fluid communication with a main package compartment.
- Conventional flexible packaging does not generally include compartments within the internal cavity of the package. Typically, a wall is simply positioned down a section of the internal cavity of the main packaging such that a division is merely created for the internal cavity. Distinct and selectively usable compartments within the cavity are not provided for in these conventional package designs. More specifically, conventional packaging lacks selectively usable and distinct compartments capable of fluid communication with each other.
- the present invention solves many of the problems that plague conventional flexible packages and packaging methods.
- Various embodiments of the present invention are directed to a main package and a segregated internal compartment package.
- the main package generally includes a plurality of outer panel portions. These panel portions can include a front panel portion, a back panel portion, and a bottom panel portion.
- the main package can include a first side panel portion and a second side panel portion.
- the formation of these panels into the main package defines a main internal compartment or cavity for holding material contents. Any of the panels can be gusseted with the processes and techniques known to one skilled in the art.
- the compartment package can include at least one internal compartment panel portion disposed between the main panel portions (e.g., back and front) to define a separate internal secondary compartment.
- the secondary internal compartment is some size generally smaller than the vertical or longitudinal length of the front and back panels, of varying available width.
- the internal compartment panel can include a plurality of defined passageways providing distinct channels of fluid communication between the secondary internal compartment and the main internal compartment.
- the secondary internal compartment having such passageways can be of varying sizes and shapes, and can be formed or sealed to define a plurality of internal compartments in communication with the main package compartment.
- Such an internal compartment can be utilized to hold or contain sauces, condiments, frozen contents, gelatinous contents, or like contents or substances, thus permitting selective communication of the contents within the internal compartment with the space or contents of the main package compartment through the passageways.
- the passageways can be of varying sizes, shapes, designs, configurations and can vary greatly in number depending on the particular needs of the manufacturer and end users.

- the package 10 generally includes a main package compartment 12 and a segregated internal compartment or package 14 .
- the main package 12 generally includes a front panel portion 16 , a back panel portion 18 , and a bottom panel portion 20 .
- the panels can be formed of one or more film webs or separately joined to define the various structures of the package 10 .
- a top panel portion 21 and/or at least one side panel portion 22 can be included in various embodiments, as demonstrated with side panels 22 in FIGS. 2 b and 5 b.
- Panel portions 16 - 20 can be operatively joined, connected, or formed (e.g., directly or indirectly sealed, or folded from one or more film materials) to define an inner cavity 26 of the main package 10 for holding, transporting, or otherwise containing material contents.
- At least one of the front 16 or back 18 panel portions includes a main sealant surface 27 for bondable joining with selectively positioned portions of the internal compartment package 14 .
- the front panel portion 16 can include front longitudinal edges 17 a, 17 b and the back panel portion 18 can include back longitudinal edges 19 .
- the cross-hatching in the figures can be utilized to generally denote the seal lines which are further described herein.
- the segregated internal compartment package 14 generally includes at least one internal compartment panel portion 24 , wherein the compartment panel portion 24 is peripherally joined to the inner surface of at least one of the main package 10 panel portions to create a second compartment cavity 28 .
- the at least one internal compartment panel 24 includes an internal panel sealant surface 30 , longitudinal compartment panel edges 32 a, 32 b and a transverse compartment panel edge or portion 34 .
- the package portions 12 - 22 are generally constructed of flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylenes laminated with other materials such as nylon, polyester, and like films. To provide for higher barriers, embodiments can use combination layers of said materials and material of the like.
- the confronting or joinable materials of the main package 12 and the internal compartment package 14 must have acceptable sealing characteristics for bonding to the respective target material.
- the sealant surface 30 of the internal panel 24 is constructed of a plastic web of polyethylene, or a material with like characteristics and heat bonding qualities for joining to the target main sealant surface 27 of one of the main package panels, such as the front 16 or back 18 panel portions.
- sealant surfaces 27 , 30 will comprise “contaminants” that permit a varying level of bonding, wherein the level of bondable attachment is dependent on the heat applied from a corresponding heat sealing bar or other device. Higher temperatures will create “destructive”, e.g., permanent, bonds while lower temperatures will create a more temporary bond for selective disengagement.
- Such bonding techniques can be applied at any sealable surface or region of the main package 12 or the internal compartment package 14 to create the desired level of bonding.
- the package of the present invention is to be formed into a stand-up pouch, but it could be a three-side-seal pouch, a pouch that displays lying down, or other known pouch or packaging designs and configurations.
- the internal panel or web 20 can be of the same width and height as the back and/or front panels, or it can be some size smaller, depending on the compartmental needs of the manufacturer or end user. Regardless, and unlike conventional techniques, the transverse compartment panel edge 34 of the internal panel 24 will generally not be bound to the main body of both the front and back panel portions.
- edges 32 of the internal compartment panel 24 will be bonded intermediate the front 16 and back panels 18 and the transverse edge 34 will be bonded to only one of the front 16 or back 18 panels, generally some distance intermediate the bottom and top edges of said one of the front 16 and back 18 panels.
- the longitudinal edges 32 a, 32 b will also be bonded to the same one of the front 16 or back 18 panels at respective edges 17 , 19 .
- Bonding descriptions of the internal compartment panel 24 to various panel designations herein will generally require particular panel portion descriptions for ease of explanation, e.g., panels 16 and 18 , but it must be noted that each of the panel portions 16 , 18 are interchangeably capable of providing the inner target surface for the internal panel 24 attachment, and the transverse edge 34 in particular.
- specific embodiments will require attachment or bonding of the internal panel 24 to the inner surface 27 of the back panel 18 where the outside surface of the front panel 16 includes graphical indicia. Attachment of the internal panel 24 to the back panel 18 will protect the indicia on the front panel 16 as specific sealing processes may require sealing bars to contact the outside of the package to bond the internal panel 24 in place.
- the internal compartment package 14 is defined by bonding the internal sealant surface 30 at the transverse edge 34 of the at least one internal compartment panel portion 24 to the main sealant surface 27 of the front panel 16 , with the back panel 18 being free from bonding contact with the transverse edge 34 .
- the orientation of the panels 16 , 18 in relation to the attachment of the internal panel portion 24 is merely for demonstrative purposes and can be interchangeable.
- the bottom panel or panel portion 20 or the bottom panel portion 20 defined by joining the ends of the front 16 and back panel 18 portions, is gusseted to create a bottom gusseted panel portion 20 g.
- gusseted panels may be denoted herein with a subscript “g” character.
- the internal panel portion 24 spans substantially the full width of the front panel 16 but is closeably sealed some distances short of the complete longitudinal length of the front panel 16 .
- the longitudinal edges 32 a, 32 b of the internal panel portion 24 are substantially and correspondingly matched and bonded to the longitudinal edges 17 a, 17 b of the front panel 16 and the bottom transverse compartment panel edge 34 of the internal panel portion 24 is bonded across the front panel 16 some distance above the bottom panel portion 20 g .
- the transverse edge 34 of the internal panel 24 is attached at a transverse seal 36 , transverse to the longitudinal edges 17 a, 17 b of the front panel portion 16 and the longitudinal edges 32 a, 32 b of the internal panel 24 itself.
- a barrier material 40 such as TeflonTM (Polytetrafluoroethylene), TeflonTM coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between the back panel 18 and the internal panel 24 proximate the line of the transverse edge 34 .
- the longitudinal edges 32 a, 32 b of the internal panel 24 are bonded intermediate the edge portions 17 , 19 of the front 16 and back panel 18 .
- the described attachment of the internal panel portion 24 creates the compartment cavity 28 , wherein the capacity or volumetric capacity of the compartment cavity 28 is measurably smaller than that of the inner cavity 26 of the main package 10 .
- FIGS. 3-5 e another embodiment of the package 10 of the present invention is shown.
- the internal compartment package 14 is also defined by bonding the internal sealant surface 30 at the transverse edge 34 of the at least one internal compartment panel portion 24 to the main sealant surface 27 of the front panel 16 , with the back panel 18 being free from bonding contact with the transverse edge 34 of the internal panel 24 .
- the bottom panel 20 or the bottom panel portion 20 defined by joining the ends of the front 16 and back panel 18 portions, is gusseted to create a bottom gusseted panel portion 20 g . As best demonstrated in FIGS.
- the internal panel portion 24 substantially spans the entire width of the front panel 16 and is closeably sealed some distance short of the complete longitudinal length of the front panel 16 at the transverse edge 34 and seal 36 .
- an intermediate longitudinal seal 38 is provided at some location intermediate the edges 32 a, 32 b, as demonstrated in FIGS. 3-3 a, and 5 b - 5 d.
- the bonding at the longitudinal seal 38 traverses from the top of the package 10 down to the transverse edge 34 and seal 36 .
- this creation of the longitudinal seal 38 between or intermediate the longitudinal edges 17 a, 17 b , 32 a, 32 b creates an internal compartment 14 measurably smaller in width than the overall width of the front panel 16 and the main package 10 .
- transverse seal 36 can create a continuous bond between the front 16 panel and the internal panel 24 along the transverse edge 34 , attachment of the back panel 18 to the transverse edge 34 and seal 36 is preferably avoided to maintain the capacity and configuration of the inner cavity 26 . Since seal bars and other bonding mechanisms and techniques known to one skilled in the art are easily utilized and often implement a seal bar across the entire width of the package 10 at the line defined by the transverse edge 34 , it may be necessary to include a material barrier 40 protection along the line of the transverse edge 34 extending from the longitudinal seal 38 to the longitudinal edges 17 b, 32 b.
- a barrier material 40 such as TeflonTM, TeflonTM coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between the back panel 18 and the front panel 16 along the width of the panels.
- This barrier 40 will prevent bonding of the back panel 18 to the transverse edge 34 along the seal 36 between the edges 17 a, 32 a and the edges 17 b, 32 b , thus also providing a barrier along the seal 36 between the longitudinal seal 38 and the edges 17 b, 32 b.
- a bond is created between the front 16 panel and the internal panel 24 along the length of the transverse seal 36 .
- the described attachment of the internal panel portion 24 creates the compartment cavity 28 , wherein the capacity or volumetric limitations of the compartment cavity 28 are measurably smaller than that of the inner cavity 26 of the main package 10 .
- the boundaries of the compartment 14 and compartment cavity 28 are generally defined in this embodiment by the u-shaped sealed continuity of the longitudinal edge 32 a, the transverse edge 34 , and the longitudinal seal 38 .
- FIGS. 5-5 a, and 5 d it may be necessary to additionally bond at least a portion of the top region of the internal panel 24 to the top portion of the front panel 16 , distal the transverse seal 36 , as shown in FIGS. 5-5 a, and 5 d.
- this top portion of the internal panel 24 is sealed to the top portion of the front panel 16 only from the longitudinal seal 38 to the longitudinal edges 17 b, 32 b. Accordingly, the openings into the internal compartment cavity 28 and the main inner cavity 26 are distinctly defined.
- FIGS. 5 this top portion of the internal panel 24 is sealed to the top portion of the front panel 16 only from the longitudinal seal 38 to the longitudinal edges 17 b, 32 b. Accordingly, the openings into the internal compartment cavity 28 and the main inner cavity 26 are distinctly defined.
- the top portion of the internal panel 24 confronting the top portion of the back panel 18 is sealed between the longitudinal edges 17 a, 32 a and the longitudinal seal 38 , and the top portion of the internal panel 24 confronting the top portion of the front panel 16 is still sealed to the top portion of the front panel 16 from the longitudinal seal 38 to the longitudinal edges 17 b, 32 b.
- Each of the seals defined herein and shown in FIGS. 5-5 a, and 5 d can be temporary or permanent and can be created using materials, techniques, and methods known to one skilled in the art.
- a temporary seal 42 bond along any of the edges or seals of the internal panel 24 .
- the temporary seal 42 is provided along the transverse edge 34 of the internal panel 24 to create at least a portion of the transverse seal 36 , as shown in FIGS. 6-7 .
- an adhesive, tape, or other selectively engageable material or substance comprises at least a portion of the transverse seal 36 such that when it is closeably engaged to temporarily bond the transverse edge 34 of the internal panel 24 to the inner surface of one panel of the main package 10 , i.e., the sealant surface 27 of the front panel 16 , the compartment cavity 28 is segregated from the inner cavity 26 .
- the compartment cavity 28 is brought into fluid communication with the inner cavity 26 .
- Such temporary seal embodiments can be utilized to isolate material contents of the two cavities 26 , 28 until such time as it is needed and/or desirable. Medical materials and contents, food, liquids, solids, and a myriad of other materials and substances can be segregated for a desired period of time or use and then selectively brought into communication with such an embodiment. Further, communication between the cavities 26 , 28 can be closed by engaging or actuating the temporary seal 42 to again provide desired segregation in those embodiments using adhesives, tapes, and the like.
- the temporary seal 42 will include a compatible tape material such that the temporary bond is broken upon sufficient pressure by the end user on the internal compartment 14 and/or main package 10 structures.
- the temporary seal 42 is created by heat sealing the transverse edge 34 of the internal panel 24 to the front 16 or back panel 18 portions in such a manner as to not create a permanent bond.
- this temporary seal 42 generated from a heat sealing technique can comprise selectively utilizing materials with known contaminant characteristics such that a relatively low heat application along the seal 42 provides temporary sealing and avoids a destructive or permanent seal.
- Various selective and temporary bonding techniques known to one skilled in the art can be employed to implement and create the temporary seal 42 without deviating from the spirit and scope of the present invention.
- the temporary seal 42 techniques and methods can be included along the longitudinal seal 38 rather than the transverse edge 34 in those packages 10 implementing the compartment package 14 of FIGS. 3-5 d.
- Various embodiments can further include a notch 44 , as shown in FIG. 5 e.
- This notch 44 is preferably located proximate the longitudinal seal 38 at the top of the package 10 and traverses down into at least the internal panel 24 and one of the front 16 or back 18 panels.
- a slit can be further provided transversely running into the notch 44 to facilitate selective tearing.
- This notch 44 permits the end user or packager to selectively open one or both of the compartments 12 , 14 to gain access into the corresponding cavities 26 , 28 . Distinct access is thus permitted. For instance, a user can rip the notch 44 across to edges 17 a, 32 a to access the internal compartment 12 , while ripping the notch 44 the opposite direction toward edges 17 b, 32 b will provide access into the main package compartment 12 .
- Each of the embodiments of the present invention can further include a tab or lip portion 39 at the top end portion of the internal panel 24 as shown in FIGS. 2 , 4 , and 7 .
- the lip portion 39 generally extends some distance outside of the opened package 10 after formation to provide yet another means of facilitating the filling of the inner cavity 26 and/or the compartment cavity 28 with contents.
- a filling machine such as a pouch machine, a form-fill-seal machine, a premade pouch filling machine or other like machines known to one skilled in the art can easily push back the internal panel 24 toward a panel (e.g., the back panel 18 ) of the package 12 opposite the panel having the sealing surface 27 (e.g., the front panel 16 ).
- the transverse edge 34 of the internal panel 24 is similarly bonded to only one of the front 16 or back 18 panels.
- the inclusion of the at least one side panel 22 makes it possible to only bond the edges 32 a, 32 b of the internal panel 24 to the same of the front 16 or back 18 panels.
- the edges 19 of the back panel 18 are free from bondable sealing with the edges 17 of the front panel 16 and the edges 32 a, 32 b of the internal panel 24 .
- the edges 32 a are bonded to edges 17 a and edges 32 b are bonded to edges 17 b.
- the longitudinal seal 38 can be included, as shown in FIG. 5 b.
- the barrier 40 and the various barrier techniques described herein can be employed at any of the sealing regions.
- expansion of the bottom panel 10 , or gusseted bottom panel 20 g, and expansion of the side panel 22 , or side panel 22 g is not substantially hindered by the bonded internal panel 24 or its sealed portions.
- the manufacturing process generally includes placing the internal panel portion 24 between the front 16 and back 18 panel portions such that the segregated multi-compartment package 10 of the present invention is formed.
- This formation process generally comprises a roller feed station 50 , a gusseting/folding station 52 , an alignment station 54 , a first seal station 56 , and a side seal station 58 .
- the formation process can further include a cooling station 60 and a cut-off station 62 .
- Each of the base steps in forming the package 10 of the present invention can be performed by known pouch machines, form-fill-seal machines, and like machines known to one skilled in the art for forming pouches and/or forming and filling pouches in the confines of the same manufacturing process.
- the internal panel 24 is fed between the front 16 and back 18 panel portions such that the internal panel 24 extends from the top of the pouch down a distance short of where the folded gusset bottom 20 g starts, depending on the length of longitudinal edges 32 a, 32 b.
- a front panel web roll 64 , a back panel web roll 66 , an internal panel web roll 68 , and a bottom panel web roll 70 are each individually positioned and fed along a general web direction using rollers, brackets, guides, and other techniques and mechanism known to one skilled in the art for forming flexible packages.
- the sealant surface 27 of the front panel web roll 64 is facing inward toward the alignable internal web 68 and the internal panel sealant surface 30 of the internal panel web roll 68 is likewise facing out toward the alignable front panel web roll 64 .
- the bottom web 70 can be gusseted at the gusseting station 52 using known techniques, mechanisms and methods known to one skilled in the art. For instance, a v-bracket can be inserted along an intermediate portion of the bottom web 70 as it is being fed through the process such that a gusset fold forms web 70 g to define what will be bottom panel 20 g for each of the packages 10 .
- the aligned webs 64 , 66 , 68 , and 70 g are positioned or laid upon each other and fed into the first seal station 56 .
- seals running along the line of the web direction but transverse to the orientation of the final package 10 can be employed.
- a first seal bar 72 can contact the outer surface of a panel, such as a portion of the front panel web 64 (or the back panel web 66 ) to create the transverse seal 36 , and/or the temporary seal 42 to bondably attach the transverse edge 34 of the internal web 68 .
- a second seal bar 74 can contact the outer surface of the front panel web 65 (or the back panel web 66 ) to fully seal the bottom gusseted panel web 70 g to the front web 65 and/or the back web 66 .
- the side seal station 58 can include at least one side seal bar 76 , and preferably two side seal bars 76 , positioned and designed to contact the outer portion of the webs to intermediately seal the longitudinal edges 32 of the internal panel web 68 to the respective confronting edges 17 , 19 of the front 64 and back 66 panel webs.
- a seal bar can be implemented at this stage to selectively seal along the package to form the longitudinal seal 38 described herein.
- pieces or strips of TeflonTM, or similar materials having beneficial heat resistant qualities have been placed at the designated target regions described herein so that unwanted bonding of particular panel portions is avoided.
- each package 10 can enter a cooling station 60 .
- the cooling station 60 can include at least one cooling bar 78 which is applied along the various seals, e.g., the seals created at the side seal station 58 , to lower the web material temperature to further promote and stabilize the bonds created.
- each package 10 still contiguously linked, can be separated to define the distinct package 10 at the cut-off station 62 .
- the cut-off station 62 can include a cutting device 80 such as a blade or other known mechanism that can trim the edges of the package 10 and cut the end package 10 from the adjacently joined package 10 . Other trimming devices and mechanisms can further be employed to trim the various edges of the package 10 .

Description
- This application is a Continuation-In-Part Application of U.S. application Ser. No. 11/857,292, filed Sep. 18, 2007, which in turn is a Divisional Application of U.S. application Ser. No. 10/456,971, filed Jun. 6, 2003 and now abandoned, which in turn claims the benefit of U.S. Provisional Application No. 60/386,798, filed Jun. 6, 2002; wherein each of the above-referenced applications and disclosures are hereby incorporated herein by reference in their entirety.
- The present invention relates generally to flexible packaging and, more particularly, to flexible packaging having at least one segregated internal compartment capable of fluid communication with a main package compartment.
- Conventional flexible packaging does not generally include compartments within the internal cavity of the package. Typically, a wall is simply positioned down a section of the internal cavity of the main packaging such that a division is merely created for the internal cavity. Distinct and selectively usable compartments within the cavity are not provided for in these conventional package designs. More specifically, conventional packaging lacks selectively usable and distinct compartments capable of fluid communication with each other.
- As a result, there is a need for a flexible package that substantially solves the above-referenced problems with conventional package designs, configurations, and manufacturing methods.
- The present invention solves many of the problems that plague conventional flexible packages and packaging methods. Various embodiments of the present invention are directed to a main package and a segregated internal compartment package. The main package generally includes a plurality of outer panel portions. These panel portions can include a front panel portion, a back panel portion, and a bottom panel portion. In addition, the main package can include a first side panel portion and a second side panel portion. The formation of these panels into the main package defines a main internal compartment or cavity for holding material contents. Any of the panels can be gusseted with the processes and techniques known to one skilled in the art. The compartment package can include at least one internal compartment panel portion disposed between the main panel portions (e.g., back and front) to define a separate internal secondary compartment.
- In one embodiment, the secondary internal compartment is some size generally smaller than the vertical or longitudinal length of the front and back panels, of varying available width. Further, the internal compartment panel can include a plurality of defined passageways providing distinct channels of fluid communication between the secondary internal compartment and the main internal compartment.
- The secondary internal compartment having such passageways can be of varying sizes and shapes, and can be formed or sealed to define a plurality of internal compartments in communication with the main package compartment. Such an internal compartment can be utilized to hold or contain sauces, condiments, frozen contents, gelatinous contents, or like contents or substances, thus permitting selective communication of the contents within the internal compartment with the space or contents of the main package compartment through the passageways. The passageways can be of varying sizes, shapes, designs, configurations and can vary greatly in number depending on the particular needs of the manufacturer and end users.

It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. For illustrative purposes, hatching or shading in the figures is generally provided to demonstrate sealed portions and/or integrated devices for the package.
- Referring generally to
FIGS. 1-15 , aflexible package 10 in accordance with the present invention, and the manufacturing steps for forming saidflexible package 10, are shown. Thepackage 10 generally includes amain package compartment 12 and a segregated internal compartment orpackage 14. Themain package 12 generally includes afront panel portion 16, aback panel portion 18, and a bottom panel portion 20. The panels can be formed of one or more film webs or separately joined to define the various structures of thepackage 10. - Further, a top panel portion 21 and/or at least one
side panel portion 22 can be included in various embodiments, as demonstrated withside panels 22 inFIGS. 2 b and 5 b. Panel portions 16-20 can be operatively joined, connected, or formed (e.g., directly or indirectly sealed, or folded from one or more film materials) to define aninner cavity 26 of themain package 10 for holding, transporting, or otherwise containing material contents. At least one of thefront 16 or back 18 panel portions includes amain sealant surface 27 for bondable joining with selectively positioned portions of theinternal compartment package 14. Thefront panel portion 16 can include frontlongitudinal edges back panel portion 18 can include backlongitudinal edges 19. The cross-hatching in the figures can be utilized to generally denote the seal lines which are further described herein. - The segregated
internal compartment package 14 generally includes at least one internalcompartment panel portion 24, wherein thecompartment panel portion 24 is peripherally joined to the inner surface of at least one of themain package 10 panel portions to create asecond compartment cavity 28. The at least oneinternal compartment panel 24 includes an internalpanel sealant surface 30, longitudinal compartment panel edges 32 a, 32 b and a transverse compartment panel edge orportion 34. - The package portions 12-22 are generally constructed of flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylenes laminated with other materials such as nylon, polyester, and like films. To provide for higher barriers, embodiments can use combination layers of said materials and material of the like. Generally, the confronting or joinable materials of the
main package 12 and theinternal compartment package 14 must have acceptable sealing characteristics for bonding to the respective target material. For instance, thesealant surface 30 of theinternal panel 24 is constructed of a plastic web of polyethylene, or a material with like characteristics and heat bonding qualities for joining to the targetmain sealant surface 27 of one of the main package panels, such as the front 16 or back 18 panel portions. One skilled in the art will understand that a myriad of materials and material laminates are available for selective use for themain sealant surface 27 and theinternal sealant surface 30 to facilitate the bonding attachment described herein. In one embodiment, at least one of the sealant surfaces 27, 30 will comprise “contaminants” that permit a varying level of bonding, wherein the level of bondable attachment is dependent on the heat applied from a corresponding heat sealing bar or other device. Higher temperatures will create “destructive”, e.g., permanent, bonds while lower temperatures will create a more temporary bond for selective disengagement. Such bonding techniques can be applied at any sealable surface or region of themain package 12 or theinternal compartment package 14 to create the desired level of bonding. - Preferably, the package of the present invention is to be formed into a stand-up pouch, but it could be a three-side-seal pouch, a pouch that displays lying down, or other known pouch or packaging designs and configurations. The internal panel or web 20 can be of the same width and height as the back and/or front panels, or it can be some size smaller, depending on the compartmental needs of the manufacturer or end user. Regardless, and unlike conventional techniques, the transverse
compartment panel edge 34 of theinternal panel 24 will generally not be bound to the main body of both the front and back panel portions. Instead, the edges 32 of theinternal compartment panel 24 will be bonded intermediate the front 16 andback panels 18 and thetransverse edge 34 will be bonded to only one of the front 16 or back 18 panels, generally some distance intermediate the bottom and top edges of said one of the front 16 and back 18 panels. In embodiments including the at least oneside panel 22, thelongitudinal edges respective edges 17, 19. Bonding descriptions of theinternal compartment panel 24 to various panel designations herein will generally require particular panel portion descriptions for ease of explanation, e.g.,panels panel portions internal panel 24 attachment, and thetransverse edge 34 in particular. For instance, specific embodiments will require attachment or bonding of theinternal panel 24 to theinner surface 27 of theback panel 18 where the outside surface of thefront panel 16 includes graphical indicia. Attachment of theinternal panel 24 to theback panel 18 will protect the indicia on thefront panel 16 as specific sealing processes may require sealing bars to contact the outside of the package to bond theinternal panel 24 in place. - In
FIGS. 1-2 a, one embodiment of thepackage 10 of the present invention is shown. In this embodiment, theinternal compartment package 14 is defined by bonding theinternal sealant surface 30 at thetransverse edge 34 of the at least one internalcompartment panel portion 24 to themain sealant surface 27 of thefront panel 16, with theback panel 18 being free from bonding contact with thetransverse edge 34. Again, the orientation of thepanels internal panel portion 24 is merely for demonstrative purposes and can be interchangeable. Further, the bottom panel or panel portion 20, or the bottom panel portion 20 defined by joining the ends of the front 16 and backpanel 18 portions, is gusseted to create a bottom gusseted panel portion 20g. For ease of explanation and differentiation, gusseted panels may be denoted herein with a subscript “g” character. As best demonstrated inFIG. 1 and 2 a, theinternal panel portion 24 spans substantially the full width of thefront panel 16 but is closeably sealed some distances short of the complete longitudinal length of thefront panel 16. In this embodiment, thelongitudinal edges internal panel portion 24 are substantially and correspondingly matched and bonded to thelongitudinal edges front panel 16 and the bottom transversecompartment panel edge 34 of theinternal panel portion 24 is bonded across thefront panel 16 some distance above the bottom panel portion 20 g. As such, thetransverse edge 34 of theinternal panel 24 is attached at a transverse seal 36, transverse to thelongitudinal edges front panel portion 16 and thelongitudinal edges internal panel 24 itself. To prevent theinternal panel 24, and thetransverse edge 34 in particular, from sealing to theback panel 18 during formation and sealing at the transverse seal 36, abarrier material 40 such as Teflon™ (Polytetrafluoroethylene), Teflon™ coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between theback panel 18 and theinternal panel 24 proximate the line of thetransverse edge 34. During formation of thepackage 10, thelongitudinal edges internal panel 24 are bonded intermediate theedge portions 17, 19 of the front 16 and backpanel 18. The described attachment of theinternal panel portion 24 creates thecompartment cavity 28, wherein the capacity or volumetric capacity of thecompartment cavity 28 is measurably smaller than that of theinner cavity 26 of themain package 10. - In
FIGS. 3-5 e, another embodiment of thepackage 10 of the present invention is shown. In this embodiment, theinternal compartment package 14 is also defined by bonding theinternal sealant surface 30 at thetransverse edge 34 of the at least one internalcompartment panel portion 24 to themain sealant surface 27 of thefront panel 16, with theback panel 18 being free from bonding contact with thetransverse edge 34 of theinternal panel 24. Further, the bottom panel 20, or the bottom panel portion 20 defined by joining the ends of the front 16 and backpanel 18 portions, is gusseted to create a bottom gusseted panel portion 20 g. As best demonstrated inFIGS. 3 and 3 a, theinternal panel portion 24 substantially spans the entire width of thefront panel 16 and is closeably sealed some distance short of the complete longitudinal length of thefront panel 16 at thetransverse edge 34 and seal 36. However, while thelongitudinal edges front panel 16 are bonded with thelongitudinal edges internal panel 24, respectively, an intermediatelongitudinal seal 38 is provided at some location intermediate theedges FIGS. 3-3 a, and 5 b-5 d. The bonding at thelongitudinal seal 38 traverses from the top of thepackage 10 down to thetransverse edge 34 and seal 36. As such, this creation of thelongitudinal seal 38 between or intermediate thelongitudinal edges internal compartment 14 measurably smaller in width than the overall width of thefront panel 16 and themain package 10. - While the transverse seal 36 can create a continuous bond between the front 16 panel and the
internal panel 24 along thetransverse edge 34, attachment of theback panel 18 to thetransverse edge 34 and seal 36 is preferably avoided to maintain the capacity and configuration of theinner cavity 26. Since seal bars and other bonding mechanisms and techniques known to one skilled in the art are easily utilized and often implement a seal bar across the entire width of thepackage 10 at the line defined by thetransverse edge 34, it may be necessary to include amaterial barrier 40 protection along the line of thetransverse edge 34 extending from thelongitudinal seal 38 to thelongitudinal edges barrier material 40 such as Teflon™, Teflon™ coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between theback panel 18 and thefront panel 16 along the width of the panels. Thisbarrier 40 will prevent bonding of theback panel 18 to thetransverse edge 34 along the seal 36 between theedges edges longitudinal seal 38 and theedges internal panel 24 along the length of the transverse seal 36. Various applications of such a barrier material to a selected portion of a package panel known to one skilled in the art can be employed without deviating from the spirit and scope of the present invention. The described attachment of theinternal panel portion 24 creates thecompartment cavity 28, wherein the capacity or volumetric limitations of thecompartment cavity 28 are measurably smaller than that of theinner cavity 26 of themain package 10. The boundaries of thecompartment 14 andcompartment cavity 28 are generally defined in this embodiment by the u-shaped sealed continuity of thelongitudinal edge 32 a, thetransverse edge 34, and thelongitudinal seal 38. - With such an embodiment, it may be necessary to additionally bond at least a portion of the top region of the
internal panel 24 to the top portion of thefront panel 16, distal the transverse seal 36, as shown inFIGS. 5-5 a, and 5 d. InFIG. 5 , this top portion of theinternal panel 24 is sealed to the top portion of thefront panel 16 only from thelongitudinal seal 38 to thelongitudinal edges internal compartment cavity 28 and the maininner cavity 26 are distinctly defined. InFIGS. 5 a and 5 d, the top portion of theinternal panel 24 confronting the top portion of theback panel 18 is sealed between thelongitudinal edges longitudinal seal 38, and the top portion of theinternal panel 24 confronting the top portion of thefront panel 16 is still sealed to the top portion of thefront panel 16 from thelongitudinal seal 38 to thelongitudinal edges FIGS. 5-5 a, and 5 d can be temporary or permanent and can be created using materials, techniques, and methods known to one skilled in the art. These embodiments create more defined and distinct openings into thecompartment cavity 28 and theinner cavity 26 such that filling of each of saidcavities cavities - Various embodiments of the present invention can include a
temporary seal 42 bond along any of the edges or seals of theinternal panel 24. Preferably, thetemporary seal 42 is provided along thetransverse edge 34 of theinternal panel 24 to create at least a portion of the transverse seal 36, as shown inFIGS. 6-7 . In one embodiment of thetemporary seal 42, an adhesive, tape, or other selectively engageable material or substance comprises at least a portion of the transverse seal 36 such that when it is closeably engaged to temporarily bond thetransverse edge 34 of theinternal panel 24 to the inner surface of one panel of themain package 10, i.e., thesealant surface 27 of thefront panel 16, thecompartment cavity 28 is segregated from theinner cavity 26. However, when thetemporary seal 42 is opened or disengaged, thecompartment cavity 28 is brought into fluid communication with theinner cavity 26. Such temporary seal embodiments can be utilized to isolate material contents of the twocavities cavities temporary seal 42 to again provide desired segregation in those embodiments using adhesives, tapes, and the like. - In one embodiment, the
temporary seal 42 will include a compatible tape material such that the temporary bond is broken upon sufficient pressure by the end user on theinternal compartment 14 and/ormain package 10 structures. In another embodiment, thetemporary seal 42 is created by heat sealing thetransverse edge 34 of theinternal panel 24 to the front 16 or backpanel 18 portions in such a manner as to not create a permanent bond. As described herein, thistemporary seal 42 generated from a heat sealing technique can comprise selectively utilizing materials with known contaminant characteristics such that a relatively low heat application along theseal 42 provides temporary sealing and avoids a destructive or permanent seal. Various selective and temporary bonding techniques known to one skilled in the art can be employed to implement and create thetemporary seal 42 without deviating from the spirit and scope of the present invention. Further, thetemporary seal 42 techniques and methods can be included along thelongitudinal seal 38 rather than thetransverse edge 34 in thosepackages 10 implementing thecompartment package 14 ofFIGS. 3-5 d. - Various embodiments can further include a
notch 44, as shown inFIG. 5 e. Thisnotch 44 is preferably located proximate thelongitudinal seal 38 at the top of thepackage 10 and traverses down into at least theinternal panel 24 and one of the front 16 or back 18 panels. A slit can be further provided transversely running into thenotch 44 to facilitate selective tearing. Thisnotch 44 permits the end user or packager to selectively open one or both of thecompartments cavities notch 44 across toedges internal compartment 12, while ripping thenotch 44 the opposite direction towardedges main package compartment 12. - Each of the embodiments of the present invention can further include a tab or
lip portion 39 at the top end portion of theinternal panel 24 as shown inFIGS. 2 , 4, and 7. Thelip portion 39 generally extends some distance outside of the openedpackage 10 after formation to provide yet another means of facilitating the filling of theinner cavity 26 and/or thecompartment cavity 28 with contents. By providing thelip 39, a filling machine, such as a pouch machine, a form-fill-seal machine, a premade pouch filling machine or other like machines known to one skilled in the art can easily push back theinternal panel 24 toward a panel (e.g., the back panel 18) of thepackage 12 opposite the panel having the sealing surface 27 (e.g., the front panel 16). In those packages and embodiments of the present invention attaching theinternal panel 24 to thefront panel 16, this pushes theinternal panel 24 towards theback panel 18 to more clearly define and separate the opening of theinner cavity 26 and thecompartment cavity 28 such that contents designated for one cavity will not accidentally enter the other cavity. - In the embodiments of
FIGS. 2 b and 5 b, thetransverse edge 34 of theinternal panel 24 is similarly bonded to only one of the front 16 or back 18 panels. In addition, the inclusion of the at least oneside panel 22 makes it possible to only bond theedges internal panel 24 to the same of the front 16 or back 18 panels. For instance, theedges 19 of theback panel 18 are free from bondable sealing with the edges 17 of thefront panel 16 and theedges internal panel 24. Instead, theedges 32 a are bonded toedges 17 a and edges 32 b are bonded toedges 17 b. As with the other embodiments, thelongitudinal seal 38 can be included, as shown inFIG. 5 b. To prevent theedges back panel 18, thebarrier 40 and the various barrier techniques described herein can be employed at any of the sealing regions. With such an embodiment having aside panel 22, expansion of thebottom panel 10, or gussetedbottom panel 20 g, and expansion of theside panel 22, or side panel 22 g, is not substantially hindered by the bondedinternal panel 24 or its sealed portions. - Referring to
FIGS. 8-9 , the manufacturing process generally includes placing theinternal panel portion 24 between the front 16 and back 18 panel portions such that the segregatedmulti-compartment package 10 of the present invention is formed. This formation process generally comprises aroller feed station 50, a gusseting/folding station 52, analignment station 54, afirst seal station 56, and aside seal station 58. The formation process can further include acooling station 60 and a cut-off station 62. Each of the base steps in forming thepackage 10 of the present invention can be performed by known pouch machines, form-fill-seal machines, and like machines known to one skilled in the art for forming pouches and/or forming and filling pouches in the confines of the same manufacturing process. - During formation of the package, the
internal panel 24 is fed between the front 16 and back 18 panel portions such that theinternal panel 24 extends from the top of the pouch down a distance short of where the folded gusset bottom 20g starts, depending on the length oflongitudinal edges FIG. 8 , at theroller feed station 50, a frontpanel web roll 64, a backpanel web roll 66, an internalpanel web roll 68, and a bottompanel web roll 70 are each individually positioned and fed along a general web direction using rollers, brackets, guides, and other techniques and mechanism known to one skilled in the art for forming flexible packages. Thesealant surface 27 of the frontpanel web roll 64 is facing inward toward the alignableinternal web 68 and the internalpanel sealant surface 30 of the internalpanel web roll 68 is likewise facing out toward the alignable frontpanel web roll 64. Prior to final alignment of the webs 64-70 before bondable sealing, thebottom web 70 can be gusseted at thegusseting station 52 using known techniques, mechanisms and methods known to one skilled in the art. For instance, a v-bracket can be inserted along an intermediate portion of thebottom web 70 as it is being fed through the process such that a gusset fold formsweb 70 g to define what will be bottom panel 20 g for each of thepackages 10. - Referring primarily to
FIG. 9 , the alignedwebs first seal station 56. At this station, seals running along the line of the web direction but transverse to the orientation of thefinal package 10 can be employed. Specifically, afirst seal bar 72 can contact the outer surface of a panel, such as a portion of the front panel web 64 (or the back panel web 66) to create the transverse seal 36, and/or thetemporary seal 42 to bondably attach thetransverse edge 34 of theinternal web 68. Further, asecond seal bar 74 can contact the outer surface of the front panel web 65 (or the back panel web 66) to fully seal the bottomgusseted panel web 70 g to the front web 65 and/or theback web 66. Following these seals at thefirst seal station 56, the now partially-sealedwebs side seal station 58. Theside seal station 58 can include at least oneside seal bar 76, and preferably two side seal bars 76, positioned and designed to contact the outer portion of the webs to intermediately seal the longitudinal edges 32 of theinternal panel web 68 to the respective confrontingedges 17, 19 of the front 64 and back 66 panel webs. A seal bar can be implemented at this stage to selectively seal along the package to form thelongitudinal seal 38 described herein. As previously indicated, pieces or strips of Teflon™, or similar materials having beneficial heat resistant qualities have been placed at the designated target regions described herein so that unwanted bonding of particular panel portions is avoided. Following the sealing at theside seal station 58, the boundaries and seals for theinternal compartment package 14 and themain package 12 are defined for eachcontiguous package 10 passing along the web path of the machine. - As the now forming
package 10 leaves theside seal station 58 along the web path of the machine, eachpackage 10 can enter acooling station 60. Thecooling station 60 can include at least one coolingbar 78 which is applied along the various seals, e.g., the seals created at theside seal station 58, to lower the web material temperature to further promote and stabilize the bonds created. Once the cooling bars 78 have performed the cooling functions required upon application, eachpackage 10, still contiguously linked, can be separated to define thedistinct package 10 at the cut-off station 62. The cut-off station 62 can include acutting device 80 such as a blade or other known mechanism that can trim the edges of thepackage 10 and cut theend package 10 from the adjacently joinedpackage 10. Other trimming devices and mechanisms can further be employed to trim the various edges of thepackage 10. - With this manufactured package product, a compartmentalized package is created such that there is no mingling or intrusion of the contents of the
distinct compartments cavities transverse edge 34 of theinternal panel 24 is generally bonded only to one of the selectedtarget panels internal panel 24 free for movement. For instance, a bottom panel 20 g and/or aside panel 22 g are free to expand or contract contingent upon the insertion or removal of contents within theinner cavity 16, thus not detrimentally affecting the functionality of thepackage 10 or the capacity or functionality of thecompartment cavity 28. Eachcavity package portion - Referring generally to
FIGS. 10-15 , an embodiment is depicted having a plurality of inter-compartment passageways. In such an embodiment, the main package compartment orpackage cavity 26 and internal/secondary compartment orcavity 28 are again distinct or separate compartments within thepackage 10. Likewise, the general formation and structure of thepackage 10 of such an embodiment can include the various steps, configurations and designs depicted or described herein. - In this passageway embodiment, the
internal compartment package 14 can be defined by bonding or otherwise operatively joining (e.g., directly or indirectly) thetransverse edge 34 of the at least one internalcompartment panel portion 24 to themain sealant surface 27 of one of the front 16 or back 18 panels, with the other of thepanels transverse edge 34. Again, the orientation of thepanels internal panel portion 24 is merely for demonstrative purposes and can be interchangeable. Further, the bottom panel or portion 20 defined by joining or forming the ends of the front 16 and backpanel 18 portions, can be gusseted to create a bottom gusseted panel portion 20 g. - As best demonstrated in
FIGS. 11-12 , theinternal panel portion 24 can span substantially the full width of the front orback panels longitudinal edges internal panel portion 24 are substantially and correspondingly matched and joined to thelongitudinal edges 19 and the bottom transversecompartment panel edge 34 of theinternal panel portion 24 is operatively across the front orback panels 16, 18 (e.g., backpanel 18 inFIGS. 10 , 12-13) some distance above the bottom panel portion 20 g to form apassageway portion 100. The corresponding seal can be a “destruct” or permanents seal, or a more temporary seal, such as a peel seal application. - The
passageway portion 100 provides fluid communication between thesecondary compartment 28 and themain package compartment 26. For example, in one embodiment, thepassageway portion 100 can include a plurality of seal segments or lands 102 spaced or otherwise provided to define a plurality of passageways orchannels 104. A seal bar or other known device or process can be employed to seal the spacedland portions 102 to the inner sealant surface of theback panel 18, while leaving the channels oropenings 104 generally free of such bonding. The seal bar can include defined and extending segments to achieve the limited or selective contact surfaces for sealing theedge 34 to create the desired spaced lands 102. This selective sealing of thetransverse edge 34 along the inner surface of one of the main package panels can occur along any distance between the bottom and top portions of thepanels lands 102 andchannels 104 can be accomplished by any means of bonding, sealing or forming package portions known to one of ordinary skill in the art. The shape, size, and spacing of thelands 102 andchannels 104 can vary greatly according to content and package formation needs. - Like other embodiments described or depicted herein, an intermediate
longitudinal seal 38 can be provided at some location intermediate theedges longitudinal seal 38 traverses from the top of thepackage 10 down to thetransverse edge 34. As such, this creation of thelongitudinal seal 38 between or intermediate the longitudinal edges of the package creates aninternal compartment 28 divided into two or more compartments 28 a, 28 b, as demonstrated inFIG. 15 . The multiple secondary compartments 28 a, 28 b are shown inFIG. 15 opened or otherwise not sealed closed at the top of the package, but could be sealed along the top of the package, e.g., to the top of theback panel 18. Thelongitudinal seal 38 can be a temporary seal, such as a peel seal, or a destructive or permanent seal. As such, the contents of the two or more compartments withininternal compartment 28 can be brought into selective communication with the other of thecompartment 28, or themain compartment 26. This can be accomplished by manual force or pressure, cooking or heating, or a myriad of other techniques. Further, thetransverse edge 34 can include thepassageway portion 100 across its entire length, or just across a limited length or width of the package with the remainder of the edge beyondseal 38 being free of passageways. - To prevent the
internal panel 24, and thetransverse edge 34 in particular, from sealing to one or more of the panels (e.g., front and/or back) during formation and sealing, abarrier material 40 such as Teflon™, Teflon™ coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between the panels and theinternal panel 24 proximate the line of thetransverse edge 34. During formation of thepackage 10, thelongitudinal edges internal panel 24 are bonded intermediate the edge portions of the front 16 and backpanel 18. The described attachment of theinternal panel portion 24 creates thecompartment cavity 28, wherein the capacity or volumetric limitations of thesecondary compartment 28 can be measurably smaller than that of theinner cavity 26 of themain package 10. - In use, the
secondary compartment 28 can be filled with material contents capable of selective communication with themain package compartment 26. For instance, frozen, semi-frozen, gelatinous, granular, solid, and other like material contents 11 can occupy thesecondary compartment 28 such that they do not readily traverse thechannels 104 of thepassageway portion 100 until desired. However, traversal can be initiated by heating and transforming the structure of the contents, squeezing or otherwise forcing the contents through thechannels 104, or via a myriad of other techniques or methods. For example, thesecondary compartment 28 could include a frozen fluid, such as a sauce, that melts upon the application of heat, which in turn causes the fluid to flow through thechannels 104 and into themain compartment 26 where compatible contents, such as pasta or rice, are present. This allows for the contents 11 of thesecondary compartment 28 to remain distinct and separate from the contents of themain compartment 26 until a time when inter-compartmental communication is desired. The selection of contents 11 that can be included incompartments - Various handles, graphics, closeable and re-closeable access devices, gusseted portions, and like features known to one skilled in the art are also envisioned for use with this invention and can be implemented without deviating from the spirit and scope of the present invention. In addition, various passageway embodiments of the present invention can further include one or more notch or tear portions located proximate a longitudinal edge or top portion of the
package 10 adapted for access through an opening. These notch portions permit the end user or packager to selectively open one or both of thecompartments cavities - The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is, therefore, desired that the present embodiment be considered in all respects as illustrative and not restrictive. Similarly, the above-described methods and techniques for manufacturing the present invention are illustrative sequential processes and are not intended to limit the methods of manufacturing the present invention to those specifically defined herein. It is envisioned that various depicted steps can be performed in differing substantive and sequential order. In addition, various unspecified steps and procedures can be performed in between those steps described herein without deviating from the spirit and scope of the present invention and the method of manufacturing the sam
