Abstract

The package generally includes at least one front and back panel joined at least partially together to define an interior accessible through an access opening. The interior is capable of storing and dispensing product and other objects or materials. Further, at least one web member can be joined to each of the front and back panel portions respectively to form at least two generally parallel chambers and/or channels that extend generally along at least a portion of the access opening. In one embodiment, each of the chambers includes a reservoir or storage portion and a closure portion in fluid communication such that either the reservoir portion or the closure portion are generally inflated or expanded to correspondingly close or open the access opening.

Claims (27)

1. A package for holding material, the package comprising:
a first panel portion;
a second panel portion, the first and second panel portions operably connected to define an interior cavity therebetween, the interior cavity accessible through an access opening;
at least one fluid containment chamber operably disposed along a portion of the first panel portion, the at least one fluid containment chamber having a reservoir portion and a closure portion in fluid communication, the closure portion positioned proximate the access opening; and a fluid disposed in the fluid containment chamber and capable of fluid communication between the reservoir portion and the closure portion of the at least one fluid containment chamber such that pressure on the reservoir portion correspondingly moves the fluid from the reservoir portion into the closure portion to generally block the access opening.
2. The package of claim 1, wherein the fluid is a gas.
3. The package of claim 1, wherein the at least one fluid containment chamber further includes a fluid regulator in fluid communication with and disposed intermediate the reservoir portion and the closure portion.
4. The package of claim 3, wherein the fluid regulator comprises a narrow channel intermediate the reservoir portion and the closure portion.
5. The package of claim 3, wherein the fluid regulator comprises a valve device intermediate the reservoir portion and the closure portion.
6. The package of claim 1, wherein the at least one fluid containment chamber includes first and second opposing fluid containment chambers.
7. The package of claim 1, further including a top seal defined generally by the sealing of a top length of each of the first and second panel portions
8. The package of claim 1, further comprising a handle portion.
9. The package of claim 8, wherein the handle portion includes an aperture defined through a portion of the package.
10. The package of claim 1, further comprising a bottom panel portion extending between and generally transverse to the first and second panel portions.
11. The package of claim 10, wherein the bottom panel portion is gusseted to facilitate generally upright standing of the package.
12. The package of claim 1, wherein the first and second panel portions are formed of one generally contiguous web of material.
13. The package of claim 1, wherein the first and second panel portions are formed of generally distinct webs of material.
14. The package of claim 1, further comprising a gas release aperture disposed on a portion of the first panel portion or the second panel portion to permit release of gaseous pressure from within the interior cavity.
15. The package of claim 1, wherein the fluid is a liquid.
16. A flexible package, comprising:
a front panel portion having an interior surface and an exterior surface;
a back panel portion having an interior surface and an exterior surface, the front and back panel portions operably connected to define an inner portion of the package, the inner portion accessible through an access opening;
a first fluid chamber disposed along a portion of the interior surface of the front panel portion, the first fluid chamber having a first reservoir portion and a first closure portion in fluid communication;
a second fluid chamber disposed along a portion of the interior surface of the back panel portion, the second fluid chamber having a second reservoir portion and a second closure portion in fluid communication, the first and second closure portions positioned opposite one another proximate the access opening; and a fluid disposed in the first and second fluid chambers and capable of communication between the respective reservoir portions and closure portions, with movement of the fluid from the reservoir portions to the closure portions correspondingly causing the opposed closure portions to abutably seat against one another to generally block the access opening.
17. The package of claim 16, wherein the fluid is a gas.
18. The package of claim 16, wherein the first and second fluid chambers include a fluid regulator in fluid communication with and disposed intermediate the respective reservoir portions and the closure portions of the first and second fluid chambers.
19. The package of claim 18, wherein the fluid regulator comprises a narrow channel intermediate the respective reservoir portions and the closure portions.
20. The package of claim 18, wherein the fluid regulator comprises a valve device intermediate the respective reservoir portions and the closure portions.
21. The package of claim 16, further comprising a gusseted bottom panel portion extending between the front and back panel portions to facilitate generally upright standing of the package.
22. A method for forming a flexible package having a fluid actuated closure, the method comprising:
providing a roll of flexible web material to a package forming machine;
feeding the web material into and through the package forming machine to a folding station to fold the web material to define front and back panel portions;
introducing first and second chamber web portions at an opening in the fold between the front and back panel portions;
sealing the first chamber web portion to the front panel portion generally around a first shaping member to define a first chamber having fluid therein; and sealing the second chamber web portion to the back panel portion generally around a second shaping member to define a second chamber having fluid therein and being opposed to the first chamber, the first and second chambers having reservoir and closure portions, with the closure portions being generally opposed to one another at an access opening to facilitate abuttable seating of the closure portions against one another upon fluid inflation of the closure portions to selectively provide access into the package at the access opening.
23. The method of claim 22, further including introducing fluid into the first and second chambers by way of the respective first and second shaping members.
24. The method of claim 23, wherein the fluid introduced into the first and second chambers is a gas.
25. The method of claim 23, wherein the fluid introduced into the first and second chambers is a liquid.
26. The method of claim 22, further including providing a fluid regulator intermediate the reservoir and closure portions of the first and second chambers to regulate fluid therebetween.
27. A flexible package, comprising:

a first panel portion having an interior surface and an exterior surface;

a second panel portion having an interior surface and an exterior surface, the first and second panel portions operably connected to define an inner compartment of the package, the inner compartment accessible through an access opening;
first means for retaining fluid, the first means disposed along a portion of the interior surface of the first panel portion;

second means for retaining fluid, the second means disposed along a portion of the interior surface of the second panel portion; and a fluid disposed and capable of displacement within the first and second means to facilitate abuttable seating of the first and second means against one another to selectively provide access into the inner compartment at the access opening.
