Abstract
A pouch includes first and second opposing pouch walls and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls. At least one of the plurality of protuberances includes a first component extending from the at least one of the first or second pouch walls and a second component extending at a non-zero angle from the first component. The flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
Claims (20)
1. A pouch, comprising:
first and second opposing pouch walls; and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls; and at least one of the plurality of protuberances including a first component that extends from the at least one of the first or second pouch walls and a second component that extends at a non-zero angle from the first component;
wherein the flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
first and second opposing pouch walls; and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls; and at least one of the plurality of protuberances including a first component that extends from the at least one of the first or second pouch walls and a second component that extends at a non-zero angle from the first component;
wherein the flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
2. The pouch of claim 1, wherein the first and second opposing pouch walls are a thermoplastic resin, and the plurality of flow channel protuberances is integral with and extends from a first side of a base member, and a second side of the base member is attached to the inner surface of at least one of the first or second pouch walls.
3. The pouch of claim 2, wherein the second side of the base member is attached to the inner surface of at least one of the first or second pouch walls by a thermoplastic weld layer.
4. The pouch of claim 1, wherein the plurality of flow channel protuberances is separately extruded and applied to the inner surface of the at least one of the first or second pouch walls.
5. The pouch of claim 1, wherein the second component extends at a non-zero angle from an intermediate region of the first component between a base end and a distal end.
6. The pouch of claim 1 further comprising an airtight closure mechanism disposed at the opening of the pouch, and a one-way valve in fluid communication with the flow channel.
7. A pouch, comprising:
first and second opposing pouch walls;
a flow channel profile disposed on an inner surface of the first pouch wall and a complementary groove disposed on an inner surface of the second pouch wall to releasably engage with the flow channel profile to define a flow channel between the first and second pouch walls;
wherein the flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
first and second opposing pouch walls;
a flow channel profile disposed on an inner surface of the first pouch wall and a complementary groove disposed on an inner surface of the second pouch wall to releasably engage with the flow channel profile to define a flow channel between the first and second pouch walls;
wherein the flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
8. The pouch of claim 7, wherein the first and second opposing pouch walls are a thermoplastic resin, and the flow channel profile is integral with and extends from a first side of a base member and a second side of the base member is attached to the inner surface of the first pouch wall.
9. The pouch of claim 8, wherein the second side of the base member is attached to the inner surface of the first pouch wall by a thermoplastic weld layer.
10. The pouch of claim 7, wherein a plurality of flow channel profiles is separately extruded and applied to the inner surface of the first pouch wall.
11. The pouch of claim 7 further comprising a valve disposed in the opening of the pouch and a resealable closure mechanism disposed proximate a mouth of the pouch to seal the pouch, wherein the flow channel profile is segmented, and the first and second pouch walls define the mouth.
12. The pouch of claim 11, wherein the flow channel is in fluid communication with the valve.
13. A pouch, comprising:
a pouch wall; and a flow channel profile comprising a first component extending from the pouch wall and a second component extending at a non-zero angle from the first component and disposed on an inner surface of the pouch wall to define a flow channel disposed between the pouch wall and an opposing surface and that extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
a pouch wall; and a flow channel profile comprising a first component extending from the pouch wall and a second component extending at a non-zero angle from the first component and disposed on an inner surface of the pouch wall to define a flow channel disposed between the pouch wall and an opposing surface and that extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
14. The pouch of claim 13, wherein the flow channel profile is segmented.
15. The pouch of claim 13, wherein the second component laterally extends at a non-zero angle from an intermediate region of one or both sides of the first component between a base end and a distal end.
16. The pouch of claim 13, wherein a plurality of flow channel profiles is separately extruded and applied to the inner surface of the pouch wall.
17. The pouch of claim 13, wherein the pouch wall and the opposing surface are a thermoplastic resin, and the flow channel profile is integral with and extends from a first side of a base member and a second side of the base member is attached to the inner surface of the pouch wall.
18. The pouch of claim 17, wherein the second side of the base member is attached to the inner surface of the pouch wall by a thermoplastic weld layer.
19. The pouch of claim 17 further comprising a valve disposed in the opening of the pouch and a resealable airtight closure mechanism disposed proximate a mouth of the pouch to seal the pouch, wherein the pouch wall and the opposing surface define the mouth.
20. The pouch of claim 19, wherein the flow channel is in fluid communication with the valve.
