Abstract

An offset resealable closure mechanism adapted to provide an airtight seal for a pouch includes a first elongate closure element and a second elongate closure element. The first elongate closure element includes a first elongate closure profile extending therefrom and a second elongate closure element includes first and second legs extending therefrom to define a channel. A sealing flange extends across the channel and includes a slit therethrough adapted to receive the first elongate closure profile. The sealing flange forms an airtight seal with the first elongate closure profile when the closure mechanism is occluded.

Claims (20)

1. A closure mechanism, comprising:
a first base and a second base;

an elongate channel defined by a first leg spaced apart from a second leg, each leg extending from the first base and having a respective distal end;

a sealing flange attached to and extending from the respective distal ends of each of the first and second legs, the sealing flange includes a slit therethrough that extends along a length of the channel between the first leg and the second leg; and an elongate profile that extends laterally from the second base, wherein the profile extends through the slit into the channel to releasably engage with the elongate channel when the closure mechanism is in an occluded state.
2. The closure mechanism of claim 1, wherein the sealing flange forms a seal against the elongate profile.
3. The closure mechanism of claim 2, wherein at least one of the first base the first leg or the second leg includes an aperture therethrough.
4. The closure mechanism of claim 3, wherein the sealing flange is integral to a first pouch sidewall.
5. The closure mechanism of claim 1, wherein a plurality of elongate channels is each defined by first and second spaced apart legs, each of the first and second legs extending from the first base, a respective distal end of each of the first and second legs is attached to the sealing flange that includes a plurality of slits therethrough, wherein each of the plurality of slits extends along each of the plurality of channels, and each of a plurality of profiles laterally extends from the second base through each slit into each of the corresponding plurality of channels to releasably engage with each of the corresponding plurality of elongate channels when the closure mechanism is in an occluded state.
6. The closure mechanism of claim 5, wherein the first base or an exterior leg includes an aperture that extends between the channel and an exterior environment.
7. The closure mechanism of claim 5, wherein an interior leg includes an aperture therethrough.
8. The closure mechanism of claim 1, wherein the sealing flange comprises a polyolefin plastomer.
9. The closure mechanism of claim 1, wherein the elongate profile includes a post and an arrow-shaped head disposed at a distal end of the post, and a textured portion along the length of the elongate profile to provide tactile and/or audible sensations when the closure mechanism is occluded.
10. A pouch, comprising:

first and second pouch sidewalls, each having respective outer and inner surfaces and attached to one another to define a mouth between the respective inner surfaces thereof;
a closure element attached to the first pouch sidewall and having an upper flange and a lower flange and an elongate channel comprising first and second legs extending from a first base with each leg having a respective distal end;
a sealing flange attached to and extending from the upper flange and the lower flange, the sealing flange having a slit therethrough that extends along a length of the elongate channel, wherein the distal end of each of the first and second legs is attached to the sealing flange; and a second base attached to the second pouch sidewall and having an elongate profile extending therefrom;
wherein the elongate profile extends into and releasably engages the channel through the slit when the elongate channel and the elongate profile are occluded.
11. The pouch of claim 10, wherein the sealing flange forms an airtight seal against the elongate profile.
12. The pouch of claim 11, wherein at least one of the first base the first leg or the second leg includes an aperture therethrough.
13. The pouch of claim 10, wherein the sealing flange is integral to the first pouch sidewall.
14. The pouch of claim 10, wherein the closure element and the second base are attached to the outer surfaces of the first and second pouch sidewalls, respectively.
15. The pouch of claim 10, wherein the sealing flange comprises a layer made of a polyolefin plastomer.
16. The pouch of claim 10 further comprising a one-way valve disposed in or on at least one of the first and second pouch sidewalls or an edge thereof and a textured portion along the length of the elongate profile to provide tactile and/or audible sensations when the elongate channel and the elongate profile are occluded.
17. A pouch, comprising:
first and second pouch sidewalls, each having respective outer and inner surfaces and attached to one another to define a mouth between the respective inner surfaces thereof;
a first closure element comprising an elongate channel having first and second spaced apart legs extending from a first base having an aperture extending therethrough between the legs;
a sealing flange attached to and extending between the first and second spaced apart legs and having a slit therethrough that extends along a length of the elongate channel; and a second closure element attached to the second pouch sidewall and comprising an elongate profile extending from a second base;
wherein the first and second spaced apart legs are attached at a respective distal end thereof to the sealing flange, and the elongate profile forms an airtight seal with the sealing flange when the first and second closure elements are in an occluded state.
18. The pouch of claim 17, wherein the first and second closure elements are attached to the outer surfaces of the first and second pouch sidewalls, respectively.
19. The pouch of claim 18, wherein the sealing flange is integral to the first pouch sidewall.
20. The pouch of claim 17, wherein the sealing flange comprises a layer made of a polyolefin plastomer.
