Storage system having a disposable vacuum bag
View Patent ↗The present invention provides a storage system having a storage device having at least one polymeric sheet sealed along a portion of its' periphery to provide an opening to a storage space; a resealable closure structure adapted to seal the opening to the storage space, the resealable closure structure comprising selectively engaging male and female profiles and a sealing compound comprising liquid silicone and at least one filler in proportions suitable for at least incidental contact to food items contained within the storage space; a vacuum valve assembly disposed on the polymeric sheet; a stand-off structure disposed adjacent to the vacuum valve assembly, wherein the stand-off structure has a series of raised surfaces facing the vacuum valve assembly; a portable vacuum pump assembly structured to engage the vacuum valve assembly; and a liquid separator assembly coupled to the portable vacuum pump assembly.
1. A storage bag comprising:
at least one polymeric sheet;
wherein the polymeric sheet has at least a top portion, a bottom portion, and a side portion;
wherein the polymeric sheet is sealed along at least a portion of the side and bottom portions thereby defining a storage bag having a storage space;
a closure comprising a pair of opposed interengaging profile members;
wherein the opposed interengaging profile members are capable of repeated engagement and disengagement; and
wherein the closure is located along the top portion of the polymeric sheet;
a grease composition along at least a substantial portion of the closure,
wherein the grease composition is positioned at least proximal to at least one of the opposed interengaging profile members; and
wherein both when the opposed interengaging profile members are engaged and when the opposed interengaging profile members are disengaged and again engaged, the grease composition creates a selectively reversible gas-permeation resistant closure;
a vacuum valve assembly integrated with a portion of a first panel of the storage bag;
wherein the vacuum valve assembly has a substantially flat surface coupled to an exterior portion of the first panel of the storage bag;
wherein the vacuum valve assembly is configured to accommodate a vacuum pump for removal of fluids from the storage space;
a strip of film positioned within the interior of the storage bag and coupled to at least a portion of the first panel of the storage bag, the strip of film having a series of channels on a first side thereof, wherein the channels face the vacuum valve assembly and provide a communication passage for removal of fluids from the storage bag.
2. The storage bag of claim 1 , wherein the grease composition is positioned as a continuous bead along at least a portion of the closure.
3. The storage bag of claim 1 , wherein the grease composition is positioned on at least one of the opposed interengaging profile members.
4. The storage bag of claim 1 , wherein the grease composition maintains chemical stability throughout a temperature range suitable for food storage and packaging.
5. The storage bag of claim 4 , wherein the grease composition has a work penetration value of 290 to 340.
6. The storage bag of claim 1 , wherein only a portion of the periphery of the stand-off structure is coupled to the first panel of the storage bag.
7. The storage bag of claim 1 , wherein the distance between the first side of the strip of film and the vacuum valve assembly is from 0.003 inches to 0.25 inches.
8. The storage bag of claim 1 , wherein the pair of opposed interengaging profile members is a first pair of opposed interengaging profile members, wherein the closure comprises a second pair of opposed interengaging profile members, and wherein the first pair of opposed interengaging profile members extend the length of the opening the second pair of opposed interengaging profile members extend the length of the opening and substantially parallel to the first pair of opposed interengaging profile members.
9. The storage bag of claim 8 , wherein the grease composition is positioned within the space between the first pair of opposed interengaging profile members and the second pair of opposed interengaging profile members.
