Pouch with breakable seals
A wipe pouch has a first compartment containing a first chemical, a second compartment containing a second chemical, and a third compartment containing a dry wipe. In certain embodiments, a first and second frangible seals separate the compartments. When ready for use, the first frangible seal is broken to mix bleach in the first compartment with WFI in the second compartment. The user then breaks the second frangible seal to saturate the wipe in the third compartment with the bleach/WFI mixture from the first and second compartments.
1 . A wipe pouch, comprising:
a first compartment having a one-way filling valve coupled to the first compartment, said first compartment containing a first liquid chemical, wherein the first chemical is filled into the first compartment through the one-way filling valve following irradiation sterilization of the wipe pouch;
a second compartment containing a second liquid chemical that is present during irradiation sterilization of the wipe pouch;
a third compartment containing a dry wipe that is present during irradiation sterilization of the wipe pouch;
a first coupling assembly coupling the first compartment to the second compartment and having a closed configuration in which the first compartment does not communicate with the second compartment, and an opened configuration in which the first compartment communicates with the second compartment;
a second coupling assembly coupling the second compartment to the third compartment and having a closed configuration in which the second compartment does not communicate with the third compartment, and an opened configuration in which the second compartment communicates with the third compartment; and
a third coupling assembly coupling the first compartment to the third compartment and having only a closed configuration in which the first compartment does not communicate directly with the third compartment.
2 . The pouch of claim 1 , wherein the at least one-way filling valve is configured to permit a liquid to be filled into the first and/or second compartment while preventing the liquid from escaping the first and/or second compartment.
3 . The pouch of claim 1 , further comprising a first one-way filling valve coupled to the first compartment and a second one-way filling valve coupled to the second compartment.
4 . The pouch of claim 3 , wherein the first one-way filling valve is configured to permit a liquid to be filled into the first compartment while preventing the liquid from escaping the first compartment, and the second one-way filling valve is configured to permit a liquid to be filled into the second compartment while preventing the liquid from escaping the second compartment.
5 . The pouch of claim 1 , wherein said first and second coupling assemblies each comprise a frangible seal.
6 . The pouch of claim 1 , wherein said first coupling assembly is weaker than said second coupling assembly, whereby said first coupling assembly is opened without opening said second coupling assembly, to communicate the first chemical with the second chemical.
7 . The wipe pouch of claim 1 , wherein said third coupling assembly is a permanent coupling that cannot be opened.
8 . The wipe pouch of claim 1 , wherein said wipe pouch is flat.
9 . The wipe pouch of claim 1 , wherein said third coupling assembly is continuous with said second coupling assembly.
10 . The wipe pouch of claim 1 , wherein said second coupling assembly and said third coupling assembly extend an entire width of said wipe pouch.
11 . The wipe pouch of claim 1 , further comprising a top end, a bottom end, a left side end, and a right side end, defining a width from the left side end to the right side end and a height from the bottom end to the top end, and
wherein said second and third coupling assemblies extend the entire width from the left side end to the right side end, at a position between the top end and the bottom end.
12 . The wipe pouch of claim 11 , wherein said first coupling assembly extends from the top end to the second and third coupling assemblies substantially parallel to the left side end and the right side end.
13 . The wipe pouch of claim 1 , wherein said first coupling assembly extends from the top end to the second and third coupling assemblies substantially parallel to the left side end and the right side end.
14 . A method of using a pouch having a first compartment formed in the wipe pouch and containing a first chemical, the first compartment having a one-way fill valve whereby the first chemical is filled into the first compartment following irradiation sterilization of the wipe pack, wherein the first chemical is filled into the first compartment following irradiation sterilization of the pouch, a second compartment formed in the wipe pouch and containing a second chemical that is present during irradiation sterilization of the wipe pouch, a third compartment formed in the wipe pouch and containing a dry wipe that is present during irradiation sterilization of the wipe pouch, a first coupling assembly for selectively coupling the first compartment to the second compartment, a second coupling assembly for selectively coupling the second compartment to the third compartment, the method comprising, and a third coupling assembly coupling the first compartment to the third compartment and having only a closed configuration in which the first compartment does not communicate directly with the third compartment:
maintaining the first coupling assembly in a closed configuration in which the first compartment does not communicate with the second compartment;
maintaining the second coupling assembly in a closed configuration in which the second compartment does not communicate with the third compartment;
breaking the first coupling assembly without breaking the third coupling assembly, to place the first coupling assembly into an opened configuration in which the first compartment communicates with the second compartment to mix the first and second chemicals; and
breaking the second coupling assembly without breaking the third coupling assembly, to place the second coupling assembly into an opened configuration in which the second compartment communicates with the third compartment to saturate the wipe with the mixed first and second chemicals.
