Abstract
A valve for a reclosable container comprises first and second opposing layers of a film material, wherein an overlap region of the second layer overlaps the container, and the first layer is sealed to the second layer around a portion of the second layer. The second layer is sealed to the container around a periphery of the overlap region, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers. First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the container and the other of the first and second apertures is in fluid communication with an exterior of the container. Vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the container.

VALVE FOR A RECLOSABLE CONTAINER
[0001] Blank [0002] Blank [0003] Blank BACKGROUND OF THE INVENTION
1. Field of the Invention [0004] The present invention relates generally to valves, and particularly to a valve that may be used on a reclosable container, such as a pouch.
2. Description of the Background of the Invention [0005] Food or other perishables are often stored in reclosable containers such as reclosable thermoplastic pouches. To keep food stored inside a pouch fresh for an extended period, a user may evacuate air out of the pouch before completely sealing a closure mechanism of the pouch. Other reclosable pouches have been developed that have a valve that allows air to be evacuated from the pouch after the closure mechanism has already been sealed.
[0006] Some pouch valves have a patch of thermoplastic material covering an aperture in a pouch wall and sealed over a limited area of the pouch wall around a periphery of the patch.
The patch has an aperture therethrough that is offset from the aperture in the pouch wall.
Pressure from outside of the pouch forces the patch against the pouch wall keeping the valve closed. However, pressure from within the pouch forces the patch to separate from the pouch wall to allow air to flow through both apertures and out of the pouch. Another valve has a highly cohesive fluid in the space between the offset apertures to resist separation of the patch and the pouch wall. Still another valve has a porous layer of material secured over the aperture in the pouch wall, wherein the porous layer has a smaller area than the patch.
The patch has an aperture therethrough that is offset from the aperture in the pouch wall.
Pressure from outside of the pouch forces the patch against the pouch wall keeping the valve closed. However, pressure from within the pouch forces the patch to separate from the pouch wall to allow air to flow through both apertures and out of the pouch. Another valve has a highly cohesive fluid in the space between the offset apertures to resist separation of the patch and the pouch wall. Still another valve has a porous layer of material secured over the aperture in the pouch wall, wherein the porous layer has a smaller area than the patch.
[0007] Other valves have a cover flap disposed over an aperture in a pouch wall, wherein the cover flap lacks an aperture. The valves have an unsealed edge that provides a path for escaping air. One such valve has a separator layer disposed between an adhesive layer disposed on an inner surface of the cover flap and an aperture in the pouch wall. The separator layer is smaller than the cover flap, but larger than the aperture and is shaped so that the adhesive layer makes asymmetrical contact with the pouch wall around a periphery of the cover flap. Pressure from within the pouch forces a portion of the cover flap having a smaller adhesive contact area to separate from the pouch wall. The valve may also have an intermediate gas permeable layer between the separator layer and the aperture.
[0008] Another valve has a cover flap that is disposed across an entire width of a pouch wall. The flap overlays one or more apertures in the pouch wall to allow air to escape from within the pouch and prevent air from entering the pouch.
[0009] Yet another valve for a pouch has a patch that is disposed across an entire width of a pouch wall and is sealed to the pouch wall around a periphery of the patch.
A first plurality of apertures extending through the pouch wall is offset from a second plurality of apertures extending through the patch. An adhesive is disposed between the first and second pluralities of apertures. Pressure from within the pouch overcomes the adhesive and forces the patch to separate from the pouch wall to allow air to escape from within the pouch.
A first plurality of apertures extending through the pouch wall is offset from a second plurality of apertures extending through the patch. An adhesive is disposed between the first and second pluralities of apertures. Pressure from within the pouch overcomes the adhesive and forces the patch to separate from the pouch wall to allow air to escape from within the pouch.
[0010] A still further valve has a patch that is sealed around a periphery of the valve over an inner or outer surface of a plastic tube. The patch may be oriented axially along a length of the tube, or circumferentially around the tube. The patch has a vent opening that is offset from a vent opening through the tube surface. A vent seal zone is defined between the patch and the tube surface. The tube is sealed on both ends such that pressure from within the tube forces the patch to separate from the tube surface to allow air to escape from within the tube.
[0011] Yet another valve has first and second zipper flanges sealed to an inside surface of a pouch wall. A line of apertures is disposed through the pouch wall, wherein the first zipper flange is attached to the pouch wall on a first side of the apertures and the second zipper flange is attached to the pouch wall on a second opposite side of the apertures. An air path is formed between the first and second zipper flanges and the apertures.
Pressure from within the pouch forces the second flange away from the first flange and pressure from outside the pouch forces the second flange into contact with the first flange.
Alternatively, the second flange is eliminated and the pouch wall on the second side of the line of apertures makes contact with the first flange. In another variation, one or more apertures disposed through the first flange are covered in flap fashion by the second flange.
SUMMARY OF THE INVENTION
Pressure from within the pouch forces the second flange away from the first flange and pressure from outside the pouch forces the second flange into contact with the first flange.
Alternatively, the second flange is eliminated and the pouch wall on the second side of the line of apertures makes contact with the first flange. In another variation, one or more apertures disposed through the first flange are covered in flap fashion by the second flange.
SUMMARY OF THE INVENTION
[0012] According to one aspect of the invention, a reclosable pouch having a valve includes opposing sidewalls and first and second opposing layers of a film material disposed across a full width of one of the sidewalls. An overlap region of the second layer overlaps the sidewall, and the first layer is sealed to the second layer around a portion of the second layer. The second layer is sealed to the sidewall around a periphery of the overlap region, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers. First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the pouch and the other of the first and second apertures is in fluid communication with an exterior of the pouch. Vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the pouch.
[0013] According to another aspect of the invention, a reclosable pouch having a valve includes opposing sidewalls and first and second opposing layers of a film material disposed across a full width of one of the sidewalls. The entire second layer overlaps the sidewall, and the first layer is sealed to the second layer around a portion of the second layer. The entire second layer is sealed to the sidewall by a thermoplastic weld layer disposed across the full width of the sidewall, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers.
First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the pouch and the other of the first and second apertures is in fluid communication with an exterior of the pouch. A seal is disposed between the first and second layers, wherein the seal encloses a region including the first and second offset apertures.
First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the pouch and the other of the first and second apertures is in fluid communication with an exterior of the pouch. A seal is disposed between the first and second layers, wherein the seal encloses a region including the first and second offset apertures.
[0014] According to yet another aspect of the invention, a reclosable pouch having a valve includes opposing sidewalls and first and second opposing layers of a film material disposed across a full width of one of the sidewalls. An overlap region of the second layer overlaps the sidewall, a region of the second layer does not overlap the sidewall, and the first layer is sealed to the second layer around a portion of the second layer. The second layer is sealed to the sidewall around a periphery of the overlap region, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers. First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the pouch and the other of the first and second apertures is in fluid communication with an exterior of the pouch. Vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the pouch.

DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0039] The present invention generally relates to valves for withdrawing a fluid from a container. While the present invention may be embodied in many forms, several embodiments are discussed herein with the understanding that embodiments illustrated are to be considered only as an exemplification of the invention and are not intended to limit the disclosure to the embodiments illustrated. For example, while a reclosable pouch and a reclosable hard-walled container are shown, any other container, such as reclosable or non-reclosable, soft- or hard-walled, to which a valve can be applied to evacuate fluid therefrom can also be used in the present invention.
[0040] Turning now to the figures, a reclosable thermoplastic pouch 50, illustrated in FIG. 1, includes a first sidewall 52, a second sidewall 54, and a valve 40.
The first and second sidewalls 52 and 54 are joined around three side edges 56a-56c by heat sealing or other sealing method known in the art to define an opening 56 leading to an interior 58.
Alternatively, the bottom side 56b may be a fold line between the first and second sidewalls 52 and 54. A closure mechanism 60 extends across a full width 62 of the pouch 50 proximate the opening 56. The closure mechanism 60 allows the pouch 50 to be repeatedly opened and closed. When occluded, the closure mechanism 60 provides an air-tight seal such that a vacuum may be maintained in the pouch interior 58 for a desired period of time, such as days, months, or years, when the closure mechanism is sealed fully across the opening 56.
The first and second sidewalls 52 and 54 are joined around three side edges 56a-56c by heat sealing or other sealing method known in the art to define an opening 56 leading to an interior 58.
Alternatively, the bottom side 56b may be a fold line between the first and second sidewalls 52 and 54. A closure mechanism 60 extends across a full width 62 of the pouch 50 proximate the opening 56. The closure mechanism 60 allows the pouch 50 to be repeatedly opened and closed. When occluded, the closure mechanism 60 provides an air-tight seal such that a vacuum may be maintained in the pouch interior 58 for a desired period of time, such as days, months, or years, when the closure mechanism is sealed fully across the opening 56.
[0041] The closure mechanism 60 comprises first and second complementary interlocking closure elements 200, 202 (illustratively shown in FIG. 12) that are attached respectively to the inner surfaces 152 and 154 of the first and second sidewalls 52 and 54.
The first interlocking closure element 200 includes one or more interlocking closure profiles 200a (illustratively shown in FIG. 12), and the second interlocking closure element 202 also includes one or more interlocking closure profiles 202a (illustratively shown in FIG. 12).
The first and second interlocking closure profiles 200a, 202a may be male and female closure profiles, respectively, as shown. However, the configuration and geometry of the interlocking profiles 200a, 202a or closure elements 200, 202 disclosed herein may vary.
The first interlocking closure element 200 includes one or more interlocking closure profiles 200a (illustratively shown in FIG. 12), and the second interlocking closure element 202 also includes one or more interlocking closure profiles 202a (illustratively shown in FIG. 12).
The first and second interlocking closure profiles 200a, 202a may be male and female closure profiles, respectively, as shown. However, the configuration and geometry of the interlocking profiles 200a, 202a or closure elements 200, 202 disclosed herein may vary.
[0042] In a further embodiment, one or both of the first and second complementary interlocking closure elements 200, 202 may include one or more textured portions, such as a bump or crosswise groove in one or more of the first and second closure profiles 200a, 202a in order to provide a tactile sensation, such as a series of clicks, as a user draws the fingers along the closure mechanism 60 to seal the closure elements across the opening. In another embodiment, the first and second interlocking closure profiles 200a, 202a include textured portions along the length of each profile to provide tactile and/or audible sensations when closing the closure mechanism 60. In addition, protuberances, for example ridges (not shown), may be disposed on the inner surfaces 152, 154 of the respective first and second sidewalls 52, 54 proximate the opening 56 to provide increased traction in a convenient area for a user to grip, such as a gripping flange, when trying to open the sealed pouch 50.
[0043] Further, in some embodiments, a sealing material such as a polyolefin material or a caulking composition such as silicone grease may be disposed on or in the interlocking profiles 200a, 202a or closure elements 200, 202 to fill in any gaps or spaces therein when occluded. The ends of the interlocking profiles 200a, 202a or closure elements 200, 202 may also be welded or sealed by ultrasonic vibrations as is known in the art.

A second layer 66 of film material is also disposed across the full width 62 of the first sidewall 52 between the first sidewall and the first layer 64. Each of the first and second layers 64 and 66 may be comprised of one or more plies of material. An exterior 68 of the pouch 50 is also shown in FIG. 1.
[0046] Referring next to an embodiment of the valve 40 as seen in FIG. 2, the second layer 66 has an overlap region 70 that overlaps the first sidewall 52. The overlap region 70 comprises the entire second layer 66. A projection 72 of the overlap region 70 of the second layer 66 is shown by the area outlined by the dashed lines in FIG. 1.
[0047] Referring now to FIGS. 1 and 2, a first aperture 74 extends through the first layer 64 and a second aperture 76 extends through the second layer 66. The first layer 64 is attached to the second layer 66 at a portion of the second layer.
Illustratively, the first layer 64 is attached to the second layer 66 around the entire periphery of the second layer, or along the full width 62 of the second layer, or along one or more peripheral edges 94, 98, 194, 198 of the second layer. The first and second layers 64 and 66 are attached to each other by a seal 78a along the peripheral edge 94 and by a seal 78b along the peripheral edge 98. Each of the seals 78a, 78b may be a heat seal or some other sealing method known in the art. The seals 78s, 78b may be continuous as shown in FIG. 6, or may be intermittent spot seals 178a, 178b as shown in FIG. 6A. The second layer 66 is sealed to the first sidewall 52 at a periphery of the overlap region 70 of the second layer 66, including for example, around a periphery of the overlap region or on at least a portion of the overlap region. In the first embodiment of FIG.
2, a thermoplastic weld layer 80 is disposed across the full width 62 of the first sidewall 52 between the sidewall 52 and the second layer 66 to seal the entire second layer 66 to the first sidewall 52. The thermoplastic weld layer 80 may be composed of any suitable thermoplastic material, such as for example, polypropylene.
Illustratively, the first layer 64 is attached to the second layer 66 around the entire periphery of the second layer, or along the full width 62 of the second layer, or along one or more peripheral edges 94, 98, 194, 198 of the second layer. The first and second layers 64 and 66 are attached to each other by a seal 78a along the peripheral edge 94 and by a seal 78b along the peripheral edge 98.

[0048] A third-aperture 82 extends through the thermoplastic weld layer 80 and a fourth aperture 84 extends through the first sidewall 52. The second, third, and fourth apertures, 76, 82, and 84 are arranged to be coincident along a line perpendicular to the sidewall 52, to allow fluid communication of the second aperture 76 with the interior 58 of the pouch 50.
The first aperture 74 in the first layer 64 is in fluid communication with the exterior 68 of the pouch 50.
The first aperture 74 in the first layer 64 is in fluid communication with the exterior 68 of the pouch 50.
[0049] One or both sidewalls, such as the second sidewall 54, may also be embossed or otherwise textured with a pattern 254. One or both surfaces of the second sidewall 54, for example the inner surface 154, may be embossed or textured between the bottom side edge 56b and the closure mechanism 60, or a separate textured or embossed patterned wall may be used to provide flow channels (not shown) within the pouch interior 58. In one embodiment, the second sidewall 54 is embossed with a diamond pattern 254 as shown in FIG.
IA, wherein the pattern extends from just beneath the closure mechanism 60 to the bottom side edge 56b and opposes the second aperture 76 that is in fluid communication with the interior 58 of the pouch 50. The flow channels may provide fluid communication between the pouch interior 58 and the valve 40 when fluid is being drawn through the valve 40.
Illustrative flow channels useful in the present invention include those disclosed in Zimmerman et al. U.S.
Patent application publication No. 2005/0286808 and Tilman et al. U.S. Patent application publication No 2006/0048483. Other flow channels useful in the present invention include those disclosed in, for example, Canadian Patent Application No. 2,635,091.

[0050] Referring next to FIG. 3, the first aperture 74 is offset from the second, third, and fourth apertures 76, 82, and 84. The first and second layers 64 and 66 are in direct contact in an intermediate seal region 86 between the offset first and second apertures 74 and 76.
Although the first and second apertures 74 and 76 are shown in FIG. 3 to be offset from one another along the width 62 of the pouch 50, in all of the embodiments described herein the first and second apertures may be offset in any relative orientation that allows for direct contact of the first and second layers 64 and 66 in the intermediate seal region 86 between the first and second apertures. A substantially airtight seal is formed between the first and second layers 64 and 66 by direct contact of the first layer to the second layer.

A substantially airtight seal is formed between the first and second layers 64 and 66 by direct contact of the first layer to the second layer.
[0051] In one embodiment, the first and second sidewalls 52, 54 and/or the closure mechanism 60 are formed from thermoplastic resins by known extrusion methods.
For example, the sidewalls 52, 54 may be independently extruded of thermoplastic material as a single continuous or multi-ply web, and the closure mechanism 60 may be extruded of the same or different thermoplastic material(s) separately as continuous lengths or strands.
Illustrative thermoplastic materials include polypropylene (PP), polyethylene (PE), metallocene-polyethylene (mPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ultra low density polyethylene (ULDPE), biaxially-oriented polyethylene terephthalate (BPET), high density polyethylene (HDPE), polyethylene terephthalate (PET), among other polyolefin plastomers and combinations and blends thereof.
Further, the inner surfaces 152, 154 of the respective sidewalls 52, 54 or a portion or area thereof may, for example, be composed of a polyolefin plastomer such as an AFFINITYTM
resin manufactured by Dow Plastics. Such portions or areas include, for example, the area of one or both of the sidewalls 52, 54 proximate and parallel to the closure mechanism 60 to provide an additional cohesive seal between the sidewalls 52, 54 when the pouch 50 is evacuated. One or more of the sidewalls 52, 54 in other embodiments may also be formed of air-impermeable film. An example of an air-impermeable film includes a film having one or more barrier layers, such as an ethylene-vinyl alcohol copolymer (EVOH) ply or a nylon ply, disposed between or on one or more of the plies of the sidewalls 52, 54. The barrier layer may be, for example, adhesively secured between the PP and/or LDPE plies to provide a multilayer film. Other additives such as colorants, slip agents, and antioxidants, including for example talc, oleamide or hydroxyl hydrocinnamate may also be added as desired. In another embodiment, the closure mechanism 60 may be extruded primarily of molten PE
with various amounts of slip component, colorant, and/or talc additives in a separate process. The fully formed closure mechanism 60 may be attached to the pouch body using a strip of molten thermoplastic weld material, or by an adhesive known by those skilled in the art, for example.
Other thermoplastic resins and air-impermeable films useful in the present invention include those disclosed in, for example, Tilman et al. U.S. Patent application publication No 2006/0048483.

[0052] With reference to FIG. 4, and not wishing to be bound by theory, the operation of the embodiment of FIGS. 2 and 3 will now be described, it being believed that the other embodiments discussed herein operate in a similar fashion. Fluid pressure from the exterior 68 of the pouch 50 that is greater than or equal to a fluid pressure of the interior 58 of the pouch compresses the pouch and forces the first and second layers 64 and 66 into contact with each other, thereby forming a seal. Further, an opening region 88 of the first layer 64 disposed directly over the second aperture 76, is subject to any pressure imbalance between the interior and exterior 58 and 68 of the pouch 50. Increased fluid pressure from the interior 58 of the pouch 50 forces the opening region 88 of the first layer 64 away from the second layer 66 and thereafter a remainder of the first layer is forced away from the second layer.
Separation of the opening region 88 from the second aperture 76 allows higher pressure fluid from within the interior 58 of the pouch 50 to spread away from the second aperture into a space 158 formed between the layers 64 and 66. An expanding zone of higher pressure fluid applies a pressure imbalance to a corresponding expanding region of the first layer 64. When the expanding zone of higher pressure fluid reaches the first aperture 74, the higher pressure fluid escapes through the first aperture to the exterior 68 of the pouch 50.
At this point, fluid can escape freely from the interior 58 of the pouch 50 to the exterior 68 of the pouch following a path 90 as depicted by the curved line and arrow in FIG. 4.

[0053] The valve 40 provides a fluid path with direct fluid communication between the interior 58 and the exterior 68 of the pouch. Although not shown, in some embodiments a second valve may be disposed in or through the closure mechanism 60 or in one of the side edges 56a-56c of the pouch. Illustrative second valves useful in the present invention include those disclosed in, for example, Newrones et at. U.S. Patent application publication No.

[0054] In use, application of vacuum pressure over the exterior of the first and second apertures 74 and 76 causes the interior 58 of the pouch below the first and second apertures to have a greater pressure than the exterior. Vacuum pressure may be applied by an evacuation pump or device or any other source of vacuum pressure known in the art, for example, by placing a vacuum cup of the evacuation pump in contact with an outer surface of the pouch and drawing a vacuum on an interior of the vacuum cup, thereby creating an expansive pressure imbalance and holding down the first and second layers 64 and 66 around the pressure imbalance.

[0056] In another embodiment depicted in FIG. 5, the first and second layers 64 and 66 and the thermoplastic weld layer 80 are disposed on the interior 58 of the pouch 50. In this embodiment, the opening region 88 of the second layer 66 is disposed directly over the first aperture 74 disposed in the first layer 64. In all of the embodiments described herein, either the first aperture 74 or the second aperture 76 may be in fluid communication with the exterior 68 of the pouch 50 or, for example, may be covered by an additional layer (not shown) to protect or hide the aperture 74 or 76. The aperture 74 or 76 that is in fluid communication with the exterior 68 of the pouch 50 may be a slit or a hole or opening of any cross-section, for example, circular, square-shaped, triangular, rectangular, pentagonal, or any other suitable shape.
[0057] Referring next to FIGS. 6 and 7, in a further embodiment, the first and second layers 64 and 66, the thermoplastic weld layer 80, and the first sidewall 52 are further attached together by a surrounding seal 92. The surrounding seal 92 may be a continuous seal as shown in FIG. 6, or may be an intermittent spot seal 192 as shown in FIG. 6A. The surrounding seal 92 may optionally be disposed between only the first and second layers 64 and 66. The surrounding seal 92 surrounds the first aperture 74 and the second aperture 76.
The surrounding seal 92 may be a heat seal or may be formed by any sealing method known in the art. Although shown as a circular seal in FIGS. 6 and 6A, the surrounding seal 92 may have any shape, for example, triangular, elliptical, square-shaped, pentagonal, hexagonal, etc.
Additionally, although the individual sealing spots that comprise the intermittent spot seals 178a, 178b, and 192 are shown in FIG. 6A to be generally circular, the individual sealing spots may be, for example, circular, elliptical, square-shaped, triangular, rectangular, pentagonal, hexagonal, or any other convenient shape. Alternatively, the first and second layers 64 and 66 and the surrounding seal 92 may be disposed on the interior 58 of pouch 50.

The first and second edge thermoplastic weld layers 96,100 and the intermittent spot seals 178a, 178b are disposed across the full width 62 (FIG. 1) of the first sidewall 52. The first and second layers 64 and 66 and the first and second edge thermoplastic weld layers 96, 100 or the intermittent spot seals 178a, 178b may alternatively be disposed on the interior 58 of the pouch 50.
The surrounding seal 92 may be a heat seal or may be formed by any sealing method known in the art. Although shown as a circular seal in FIGS. 6 and 6A, the surrounding seal 92 may have any shape, for example, triangular, elliptical, square-shaped, pentagonal, hexagonal, etc.
Additionally, although the individual sealing spots that comprise the intermittent spot seals 178a, 178b, and 192 are shown in FIG. 6A to be generally circular, the individual sealing spots may be, for example, circular, elliptical, square-shaped, triangular, rectangular, pentagonal, hexagonal, or any other convenient shape. Alternatively, the first and second layers 64 and 66 and the surrounding seal 92 may be disposed on the interior 58 of pouch 50.
[0058] In yet another embodiment, as seen in FIG. 8, first edges 94a and 94 of the first and second layers 64 and 66, respectively, are attached to the first sidewall 52 by a first edge thermoplastic weld layer 96, and second edges 98a and 98 of the first and second layers 64 and 66, respectively, are attached to the first sidewall 52 by a second edge thermoplastic weld layer 100. Alternatively, as seen in FIG. 8A, the first edges 94a and 94 of the first and second layers 64 and 66, respectively, are attached to the first sidewall 52 by the intermittent spot seal 178a, and the second edges 98a and 98 of the first and second layers 64 and 66, respectively, are attached to the first sidewall 52 by the intermittent spot seal 178b. The first and second edge thermoplastic weld layers 96,100 and the intermittent spot seals 178a, 178b are disposed across the full width 62 (FIG. 1) of the first sidewall 52. The first and second layers 64 and 66 and the first and second edge thermoplastic weld layers 96, 100 or the intermittent spot seals 178a, 178b may alternatively be disposed on the interior 58 of the pouch 50.
[0059] A still further embodiment is depicted in FIG. 9, wherein the entire second layer 66 is sealed directly to the first sidewall 52. The first edge 94a of the first layer 64 is attached to the first sidewall 52 by the first edge thermoplastic weld layer 96, and the second edge 98a of the first layer 64 is attached to the first sidewall 52 by the second edge thermoplastic weld layer 100. Alternatively, the first edge 94a of the first layer 64 is attached to the first sidewall 52 by the intermittent spot seal 178a, and the second edge 98a of the first layer 64 is attached to the first sidewall 52 by the intermittent spot seal 178b. The first and second layers 64 and 66 and the first and second edge thermoplastic weld layers 96, 100 or the intermittent spot seals 178a, 178b may alternatively be disposed on the interior 58 of the pouch 50.
[0060] Referring next to FIG. 10, in still another embodiment, a first plurality of apertures 102 extends through the first layer 64. A second plurality of apertures 104 extends through the second layer 66, wherein the second plurality of apertures 104 is offset from the first plurality of apertures 102. A third plurality of apertures 106 extends through the first sidewall 52 of the pouch 50. The second and third pluralities of apertures 104 and 106 are arranged to be coincident along a line perpendicular to the first sidewall 52, thereby allowing fluid communication of the second plurality of apertures 104 with the interior 58 of the pouch 50. Alternatively, the first and second layers 64 and 66 that have the first and second pluralities of apertures 102 and 104 respectively extending therethrough may be disposed on the interior 58 of the pouch 50.
[0061] In a yet further embodiment, as seen in FIGS. 11 and 12, the second layer 66 includes an overlap region 170 that overlaps the first sidewall 52 and a portion 108 that does not overlap with the first sidewall. The projection 172 of the overlap region 170 of the second layer 66 is shown by the area outlined by the dashed line in FIG. 11.
An edge 294 of the second layer 66 is joined to a closure flange 110 that may have a first closure element 200 disposed thereon, leaving a gap 112 across the full width 62 of the pouch 50 between the first sidewall 52 and the closure flange. A second closure element 202 may also be disposed on the second sidewall 54 opposing the first closure element 200. The closure elements 200 and 202 may be any type of complementary interlocking closure elements known in the art, as previously described herein. The second plurality of apertures 104 is in fluid communication with the interior 58 of the pouch 50 through the gap 112. The gap 112 is sealed along first and second ends 114 and 116 between the second layer 66 and the second sidewall 54. The first and second edge thermoplastic weld layers 96 and 100 extend partially under the second layer 66 to attach the first and second layers 64 and 66 together and attach the first and second layers to the first sidewall 52 and the closure flange 110, respectively. In place of the thermoplastic weld layers 96, 100, the intermittent spot seals 178a, 178b may attach the first and second layers 64 and 66 together and attach the first and second layers to the first sidewall 52 and the closure flange 110, respectively. Alternatively, the first and second layers 64 and 66 and the first and second edge thermoplastic weld layers 96, 100 or the intermittent spot seals 178a, 178b may be disposed on the interior 58 of the pouch 50.
An edge 294 of the second layer 66 is joined to a closure flange 110 that may have a first closure element 200 disposed thereon, leaving a gap 112 across the full width 62 of the pouch 50 between the first sidewall 52 and the closure flange. A second closure element 202 may also be disposed on the second sidewall 54 opposing the first closure element 200. The closure elements 200 and 202 may be any type of complementary interlocking closure elements known in the art, as previously described herein. The second plurality of apertures 104 is in fluid communication with the interior 58 of the pouch 50 through the gap 112. The gap 112 is sealed along first and second ends 114 and 116 between the second layer 66 and the second sidewall 54. The first and second edge thermoplastic weld layers 96 and 100 extend partially under the second layer 66 to attach the first and second layers 64 and 66 together and attach the first and second layers to the first sidewall 52 and the closure flange 110, respectively. In place of the thermoplastic weld layers 96, 100, the intermittent spot seals 178a, 178b may attach the first and second layers 64 and 66 together and attach the first and second layers to the first sidewall 52 and the closure flange 110, respectively. Alternatively, the first and second layers 64 and 66 and the first and second edge thermoplastic weld layers 96, 100 or the intermittent spot seals 178a, 178b may be disposed on the interior 58 of the pouch 50.
[0062] The first and second layers 64 and 66 of any of the valves 40 as disclosed herein may be independently composed of any thermoplastic material such as would be used for the first and second sidewalls 52 and 54 of the pouch 50 as described herein. Each of the first and second layers 64 and 66 may be composed of the same material as the other layer or could be independently composed of different material than the other layer. In addition, each of the first and second layers 64 and 66 may also have multiple plies, each ply being independently composed of any thermoplastic material such as would be used for the first and second sidewalls 52 and 54 of the pouch 50 as described herein, or a blend of any thermoplastic material such as would be used for the first and second sidewalls of the pouch as described herein. Illustratively, the first and second layers 64 and 66 may, for example, be composed of a polyolefin plastomer such as an AFFINITYTM resin manufactured by Dow Plastics.
[0063] FIGS. 13-15 depict various illustrative embodiments for the first and second layers 64 and 66. Referring to FIG. 13, the first layer 64 is composed of a first ply 118 and a second ply 120. Although any suitable flexible thermoplastic materials may be used for the first and second plies 118 and 120, in this embodiment, for example, the first ply 118 is composed of polypropylene or HDPE and the second ply 120 is composed of a polyolefin plastomer. The second layer 66 in FIG. 13 includes a single ply and may be made of any suitable flexible thermoplastic, but illustratively the second layer 66 is made of polypropylene, HDPE, polyolefin plastomer, or a blend of any two or all three of polypropylene, HDPE, and polyolefin plastomer. The structures of the first and second layers 64 and 66 may also be reversed such that the first layer 64 has a single ply and the second layer 66 has two plies. Other additives known to those skilled in the art may also be included in the composition of the first and second layers 64 and 66, as desired such as to improve handling and manufacturing characteristics.
[0064] As seen in FIG. 14, the first layer is substantially identical to that of FIG. 13 and the second layer 66 is composed of a first ply 122 and a second ply 124.
Although any suitable flexible thermoplastic materials may be used for the first and second plies 122 and 124 of the second layer 66, in this embodiment, for example, the first ply 122 is composed of a polyolefin plastomer and the second ply 124 is composed of polypropylene or HDPE.

The surrounding seal 392 may be a continuous seal or may be an intermittent spot seal as discussed previously for another embodiment herein regarding the surrounding seal 92.
[0071] Further, it is also contemplated that the valve 340 may be constructed independently of the container 300 and applied to the container, such as to the pouch 50, the container lid 302, or the container body 304, after or during the manufacturing thereof. One such embodiment is illustrated in FIGS. 18 and 19, wherein the valve 340 is applied to the container body 304 using an adhesive layer 384. In this embodiment, the film layer 324 of the lid 302 spans the opening 320 and includes no apertures therethrough.
Although the adhesive layer 384 is shown to attach the valve 340 to the container body 304, either of the first and second layers 364 and 366 may be, alternatively or in addition to, attached to the sidewall 316 by any suitable method known in the art, for example, directly by a thermoplastic weld layer 396b. The first aperture 374 extends through the second layer 366 and is offset from the second aperture 376 that extends through the first layer 364. The third aperture 378 extends through the thermoplastic weld layer 396b and a fourth aperture 380a extends through the sidewall 316. A fifth aperture 382a extends through the adhesive layer 384. The second, third, fourth, and fifth apertures 376, 378, 380a, and 382a are aligned along a line perpendicular to the sidewall 316 such that the second aperture 376 is in fluid communication with the interior 322 of the container body 304.

The second, third, fourth, and fifth apertures 376, 378, 380a, and 382a are aligned along a line perpendicular to the sidewall 316 such that the second aperture 376 is in fluid communication with the interior 322 of the container body 304.
[0072] Further, it is believed that the embodiments shown in FIGS. 16-19 operate in a fashion similar to the valves 40 described above. Illustratively, after the contents 318 are placed into the container body 304 and the lid 302 is applied thereto, a source of vacuum pressure (not shown) is applied over the first and second apertures 374 and 376. The flange extension 370 or the sidewall 316 provides a support surface for application of the source of vacuum pressure. As air is removed from the container body 304, the flexible material of the first and second layers 364 and 366 or the film layer 324 are compressed into the container body by atmospheric pressure. The first and second layers 364 and 366 or the film layer 324 cover and conform to the contents 3 18 as the air is removed from the container body 304.
The first and second layers 364 and 366 or the film layer 324 may be attached to the peripheral flange 368 by any suitable method known in the art, for example, by ultrasonic or thermal welding, or by application of an adhesive.
The first and second layers 364 and 366 or the film layer 324 may be attached to the peripheral flange 368 by any suitable method known in the art, for example, by ultrasonic or thermal welding, or by application of an adhesive.
[0073] In this, or in any of the embodiments shown, the valve 40 or 340, may be adhered to the pouch 50 or to the container lid 302, film layer 324, or container body 304 as described herein or by an adhesive known to those skilled in the art such as described in Engel et al.
