Definitions
- the present invention relates generally to flexible packaging and, more particularly, to flexible packaging having multiple compartments and corresponding opposing openings.
- Conventional flexible packaging does not generally include compartments within the internal cavity of the package. Those packages that do, lack conveniently placed and accessible compartment openings for filling, pouring or otherwise using the separate compartments. Distinct and selectively usable compartments within the cavity are not provided for in these conventional package designs. Further, conventional packages fail to allow for adequate handling of a package with a unique multi-compartment configuration. Moreover, these conventional packages do not provide distinct accessibility or closeability for multiple separate compartments, or the ability to access the separate openings of the compartments without tearing off or otherwise removing the top package seal or handle portion of the package.
- 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 two separate and distinct internal compartments within a flexible package.
- the package is generally formed from 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 package defines at least one internal 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 package can further include the segregated internal compartment panel portion having corresponding edge portions joined to or distinguishable from an inner surface of one of the main package panels within the internal cavity to define distinct first and second compartments of the package. Further, the package can include at least two separate openings into the package to enable selectively separate access into the compartments. The openings can include access device, such a re-closeable access device.
- a top seal portion of the package is provided intermediate the openings and provides a top dividing portion between the compartments such that the openings open out away from the top seal.
- the package can include one or more handle portions, such as an aperture in the top seal portion of the package.
- an alternate slit access opening can be provided on one or more of the outside panels, such as the front or back panels, between the handle portion and the access device. This slit opening enables filling of the package even though the top handle portion may be sealed and the access device closed.
- the package of the present invention can provide separate accessibility or closeability for multiple separate compartments, or the ability to access the separate openings of the compartments without tearing off or otherwise removing the top package seal or handle portion of the package.
- the internal panel can be uniquely sealed within the inner cavity at an inner surface of the front or back panels.
- Such a package configuration provides convenient and opposing dual accessibility into the compartments.

- the package 10 generally includes a front panel portion 12 , a back panel portion 14 , and a bottom panel portion 16 . Further, one or more side panel portions (not shown) can be included in various embodiments. Panel portions 12 - 16 can be joined to form or define an inner cavity of the main package 10 for holding, transporting, or otherwise containing material contents. One or both of the front 12 or back 14 panel portions can include a main sealant surface for bondable joining with selectively positioned portions of an internal compartment panel 30 . The joining of the front and back panels 12 , 14 can create corresponding side or seal edges 26 , 28 . Alternatively, the panels 12 - 16 can be formed of a single web material and folded or formed to define the distinct panel portions. The cross-hatching in the figures is used generally to denote sealing and/or panel edges.
- the separate internal compartment panel 30 can be bonded within the package to create or define a first or main compartment 44 , and a second compartment 46 .
- the at least one internal compartment panel 30 can include longitudinal compartment panel edges 30 a, 30 b and a generally transverse compartment bottom edge 30 c. As shown in FIG. 1 , the compartment panel edges 30 a, 30 b can correspond with or extend to side edges 26 , 28 within the package 10 .
- the package panel portions are generally constructed of flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylenes or polypropylenes 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 10 and the internal compartment panel 30 must have acceptable sealing characteristics for bonding to the respective target material.
- the sealant surface of the internal panel 30 can be 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 (e.g., internal surface) of one of the main package panels, such as the front 12 or back 14 panel portions.
- sealant surfaces 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 10 or the internal compartment panel 30 to create the desired level of bonding.
- the package of the present invention can 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 30 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.
- the edges 30 a, 30 b of the internal compartment panel 30 can be disposed intermediate the front panel 12 and back panel 14 and bonded proximate the bottom portion 16 of the package 10 .
- the side or longitudinal edges 30 a, 30 b can be bonded in forming the corresponding package seals or edges 26 , 28 .
- the longitudinal edges 30 a, 30 b can be bonded to the longitudinal edges of just one of the respective front 12 or back 14 panels. Bonding descriptions of the internal compartment panel 30 to various panel designations herein will generally require particular panel portion descriptions for ease of explanation (e.g., panels 12 and 14 ), but it must be noted that each of the panel portions 12 , 14 are interchangeably capable of providing the inner target surface for the internal panel 30 attachment. For instance, specific embodiments will require attachment or bonding of the internal panel 30 to the inner surface of the back panel 14 where the outside surface of the front panel 12 includes graphical indicia. Such attachment of the internal panel 30 to the back panel 14 will protect the indicia on the front panel 12 as specific sealing processes may require sealing bars to contact the outside of the package to bond the internal panel 30 in place.
- the internal compartment panel 30 is bonded to the internal sealant surface of the front panel at the transverse edge 30 c, with the back panel 14 being free from bonding contact with the transverse edge 30 c.
- the orientation of the panels 12 , 14 in relation to the attachment of the internal panel portion 30 is merely for demonstrative purposes and can be interchangeable.
- the internal panel portion 30 can substantially span the full width or length of the front panel 12 .

Description
- This application is a continuation-in-part of application Ser. No. 11/857,292 filed Sep. 18, 2007, which in turn is a division of application Ser. No. 10/456,971 filed Jun. 6, 2003, now abandoned, which claims the benefit of U.S. Provisional Application No. 60/386,798 filed Jun. 6, 2002, this application also claims the benefit of U.S. Provisional Application No. 61/038,877 filed Mar. 24, 2008, each of which is hereby fully incorporated herein by reference.
- The present invention relates generally to flexible packaging and, more particularly, to flexible packaging having multiple compartments and corresponding opposing openings.
- Conventional flexible packaging does not generally include compartments within the internal cavity of the package. Those packages that do, lack conveniently placed and accessible compartment openings for filling, pouring or otherwise using the separate compartments. Distinct and selectively usable compartments within the cavity are not provided for in these conventional package designs. Further, conventional packages fail to allow for adequate handling of a package with a unique multi-compartment configuration. Moreover, these conventional packages do not provide distinct accessibility or closeability for multiple separate compartments, or the ability to access the separate openings of the compartments without tearing off or otherwise removing the top package seal or handle portion of the package.
- 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 two separate and distinct internal compartments within a flexible package. The package is generally formed from 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 package defines at least one internal 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 package can further include the segregated internal compartment panel portion having corresponding edge portions joined to or distinguishable from an inner surface of one of the main package panels within the internal cavity to define distinct first and second compartments of the package. Further, the package can include at least two separate openings into the package to enable selectively separate access into the compartments. The openings can include access device, such a re-closeable access device.
- A top seal portion of the package is provided intermediate the openings and provides a top dividing portion between the compartments such that the openings open out away from the top seal. Moreover, the package can include one or more handle portions, such as an aperture in the top seal portion of the package. In one embodiment, an alternate slit access opening can be provided on one or more of the outside panels, such as the front or back panels, between the handle portion and the access device. This slit opening enables filling of the package even though the top handle portion may be sealed and the access device closed. As such, the package of the present invention can provide separate accessibility or closeability for multiple separate compartments, or the ability to access the separate openings of the compartments without tearing off or otherwise removing the top package seal or handle portion of the package.
- The internal panel can be uniquely sealed within the inner cavity at an inner surface of the front or back panels. Such a package configuration provides convenient and opposing dual accessibility into the compartments.

internal compartment panel 30 can be bonded within the package to create or define a first ormain compartment 44, and asecond compartment 46. The at least oneinternal compartment panel 30 can include longitudinalcompartment panel edges 30 a, 30 b and a generally transversecompartment bottom edge 30 c. As shown inFIG. 1 , thecompartment panel edges 30 a, 30 b can correspond with or extend toside edges package 10. - The package panel portions are generally constructed of flexible sheet material such as polyethylene, polyester, metal foil, polypropylene, or polyethylenes or polypropylenes 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 10 and theinternal compartment panel 30 must have acceptable sealing characteristics for bonding to the respective target material. For instance, the sealant surface of theinternal panel 30 can be 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 (e.g., internal surface) of one of the main package panels, such as thefront 12 or back 14 panel portions. One skilled in the art will understand that a myriad of materials and material laminates are available for selective use for the sealant surfaces to facilitate the bonding attachment described herein. In one embodiment, at least one of the sealant surfaces 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 10 or theinternal compartment panel 30 to create the desired level of bonding. - In one embodiment, the package of the present invention can 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 30 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. Theedges 30 a, 30 b of theinternal compartment panel 30 can be disposed intermediate thefront panel 12 and backpanel 14 and bonded proximate thebottom portion 16 of thepackage 10. The side orlongitudinal edges 30 a, 30 b can be bonded in forming the corresponding package seals oredges longitudinal edges 30 a, 30 b can be bonded to the longitudinal edges of just one of therespective front 12 or back 14 panels. Bonding descriptions of theinternal compartment panel 30 to various panel designations herein will generally require particular panel portion descriptions for ease of explanation (e.g.,panels 12 and 14), but it must be noted that each of thepanel portions internal panel 30 attachment. For instance, specific embodiments will require attachment or bonding of theinternal panel 30 to the inner surface of theback panel 14 where the outside surface of thefront panel 12 includes graphical indicia. Such attachment of theinternal panel 30 to theback panel 14 will protect the indicia on thefront panel 12 as specific sealing processes may require sealing bars to contact the outside of the package to bond theinternal panel 30 in place. - In one embodiment of the
package 10, theinternal compartment panel 30 is bonded to the internal sealant surface of the front panel at thetransverse edge 30 c, with theback panel 14 being free from bonding contact with thetransverse edge 30 c. Again, the orientation of thepanels internal panel portion 30 is merely for demonstrative purposes and can be interchangeable. As best demonstrated inFIGS. 1-4 , theinternal panel portion 30 can substantially span the full width or length of thefront panel 12. In this embodiment, thelongitudinal edges package panels internal compartment panel 30. Thetransverse edge 30 c of theinternal panel 30 is attached transverse to thelongitudinal edges front panel portion 12. The edge or seal 30 c can run the entire width of therespective front 12 or back 14 panels or a distance shorter than the corresponding widths of the other panels. For instance, in one embodiment the width of theinternal panel 30 can be approximately half the width of thefront front 12 or back 14 panels. Other variations in the dimensions and design of theinternal panel 30 can be employed without deviating from the spirit and scope of the present invention. - To prevent the
internal panel 30, and thetransverse edge 30 c in particular, from sealing to theback panel 14 during formation and sealing, a barrier material such as Teflon™, Teflon™ coated materials, or materials of like heat barrier qualities and characteristics can be selectively disposed between theback panel 14 and theinternal panel 30 proximate the line of the transverse seal or edge 30 c. During formation of thepackage 10, thelongitudinal edges 30 a, 30 b of theinternal panel 30 can be bonded intermediate the edges or seals 26, 28 of the front 12 and backpanel 14. The described attachment of theinternal panel portion 30 defines separate and distinct compartments and cavities. - In
FIG. 6 , another embodiment of thepackage 10 of the present invention is shown. In this embodiment, the bottom seal or edge 30 c of theinternal compartment panel 30 is sealed or otherwise disposed along the front panel 12 (or, alternatively, back panel 14) some distance above the bottom of thepackage 10. Such a configuration permits adjustment of the volumetric capacity of thesecond compartment 46 in comparison to that of the potentially largerfirst compartment 44. Again, the edge or seal 30 c of the internalcompartment panel portion 30 can be sealed to thefront panel 12 such that theseal 30 c is generally free from bonding contact with theback panel 14. 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 the transverse edge or seal 30 c, it may be necessary to include a material barrier protection along the line of thetransverse edge 30 c, as disclosed herein. The sealing or attachment of theinternal compartment panel 30 to either the front orback panels panel 30 to the other panels, such as the bottom or side panels. As such, the other flexible panels, gusseted or non-gusseted, are free to expand and contract to accommodate the internal materials or contents in thepackage 10. Agusseted bottom panel 16 can provide for the stand-up configuration for thepackage 10 as shown and described herein. - The
openings package 10 can be accessed via at least one access device. Generally, the at least one access device will include afirst device 32 and asecond device 34, as shown inFIGS. 1 , and 4-6. Thefirst device 32 can include afirst flange portion 50, asecond flange portion 52, amale profile 54 and afemale portion 56. Similarly, thesecond device 34 can include afirst flange portion 60, asecond flange portion 62, a male profile 64 and afemale portion 66. As best depicted inFIG. 5 , theflange portions first device 32 are attached or otherwise disposed on thefront panel 12 in accordance with known techniques to provide access into the first ormain compartment 44 through the first access opening 40. Theflange portions back panel 14 in accordance with known techniques to provide access into thesecond compartment 46 through the second access opening 42. As such,device 32 can be attached to a single package panel anddevice 34 can be attached to another single, distinct, package panel, such that the access devices are respectively without attachment to other seals, the internal compartment, and the like. This in turn creates the adjacent but opposing opening design as shown best inFIGS. 1 and 4 . The divisional separation of thecompartments panel 30 starts at the top with thetop portion 20 and/or seal 70 and extends down along the dividinginternal barrier panel 30 to the bottom seal or edge 30 c. The top 20, 70 is generally formed by the joinder or attachment of the tops of the front andback panels internal compartment panel 30. - The
devices back panel portions devices panels devices FIGS. 2-3 b, the consumer or end user has the ability to access the product without removing the packaging material above thedevices handle 72 or other accessories above thedevices - In one embodiment, the
package 10 can further include a fill slit or opening 80, as best shown inFIG. 3 b, andFIG. 5 a. The fill slit 80 is generally disposed between theaccess device 32 and the top 20, 70 of the package 10 (e.g., above the device 32). As such, the manufacturer or package maker can form thepackage 10 with a sealedtop access device 32, such that thepackage 10 can be filled at a later stage or facility through the fill slit 80. This, in turn, means that those filling thepackage 10 with material or contents will only have to seal off the fill slit 80 after filling, rather than the top 20, 70, which is often thicker, larger or otherwise more difficult to seal. Such an embodiment with a fill slit 80 can be employed in packages having multi-compartments, or those only having a single internal cavity andaccess device 32, as described further herein. As a result, the fill slit 80 can be positioned above one or both of thedevices package 10 or compartment. Alternatively, various embodiments of thepackage 10 could be filled through an opening or unsealed portion (e.g., top portion) of the package rather than through a fill slit 80. - In one embodiment, a
package 10 like those shown inFIGS. 2-3 b, can be modified to include just asingle access device 32 and single internal compartment or cavity, with thedevice 32 being attached to only one of thefront panel 12 or backpanel 14 portions to provide access into thepackage 10. Such embodiments could, but would not require the use of aninternal panel 30 to define multiple internal compartments. Thepackage 10 can include attachment of theaccess device 32 along or in line with the machining direction during formation of thepackage 10 rather than at a positioning transverse to the machining direction or prior to formation of the package. Moreover, the fill slit 80 configuration described herein can be employed to facilitate the filling of such a package. - Fixed zippers, slider zippers, adhesives/tapes, snap or screw cap devices, snap fasteners, hook and latch fastening, spouts, fitments, and other like techniques and devices known to one skilled in the art can be employed for use as the
access devices other access devices access devices re-closeable access devices package 10 without deviating from the present invention, including but limited to portions along or proximate one or more longitudinal sides of thepackage 10, the bottom of thepackage 10, and like configurations. For example, in an alternative embodiment, theaccess devices - Various embodiments of the present invention can include a temporary seal bond along any of the edges or seals of the
internal panel 30. Preferably, the temporary seal would be provided along the transverse edge or seal 30 c of theinternal panel 30 for those embodiments where theseal 30 c is a distance above the bottom of thepackage 10. In one embodiment of the temporary seal, an adhesive, tape, or other selectively engageable material or substance comprises at least a portion of thetransverse seal 30 c when it is closeably engaged to temporarily bond thetransverse edge 30 c of theinternal panel 30 to the inner surface of one panel of the main package 10 (e.g., the sealant surface of the front panel 12). When the temporary seal is opened or disengaged (through force, application of cooking or heat, and the like), thesecond compartment 46 is brought into fluid communication with thefirst compartment 44. Such temporary seal embodiments can be utilized to isolate material contents of the two cavities orcompartment cavities - Various embodiments can further include tear or peel portions 24, including slits, scores, perforations, notches, and the like in the
package 10. For instance, a tear notch 24 can be provided in thetop portion 20, 70 (FIG. 3 a) to facilitate removal of at least a section of thetop portion back materials 74, tabs, or tear portions, can be located proximate theopenings access devices package 10 openings. - The various formation steps and methods, isolated or combined, or variations thereof, disclosed in U.S. Patent Publication No. 20040031244 can be employed to manufacture or form the
package 10 of the present invention. As such, U.S. Patent Publication No. 20040031244 is hereby incorporated by reference herein. Further, various handles, graphics, closeable and re-closeable 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.
