Resealable packets of liquid
View Patent ↗Disclosed is a pocketable container in the form of a resealable polymeric packet designed to hold and disperse multiple doses of a useful fluid. Resealing is achieved by means of a simple yet reliable fold closure technique making possible a cost effective tool for carrying about small quantities of useful liquids, specifically hand sanitizing fluids for control of sickness and infectious disease in a human population.
1. A resealable packet, comprising:
a flexible polymeric packet holding a useful liquid;
a controlling barrier within said packet creating reservoir and dispersement chambers;
a restrictive passage in said barrier permitting fluidic communication of said useful liquid between said chambers;
an exit means for said useful liquid from said dispersement chamber;
a predetermined fold line positioned on said flexible polymeric packet in immediate parallel to said barrier and said passage in a crimping arrangement forming a cooperative relationship capable of preventing said fluid communication of said useful liquid through said passage when said flexible polymeric packet is folded and thus sealed; and
a fold holding means capable of maintaining the folded packet in said sealed condition.
2. The packet of claim 1 wherein said fold holding means is a cover.
3. The packet of claim 1 wherein said fold holding means is a tab.
4. The packet of claim 1 wherein said fold holding means is a case.
5. The packet of claim 4 wherein said case stores and seals more than one said folded packets.
6. The packet of claim 4 wherein said case is a relatively permanent object and said flexible polymeric packet is disposable and replaced in said case when depleted.
7. The packet of claim 4 wherein said case contains unintended discharge and/or leakage from said flexible polymeric packet.
8. The packet of claim 1 wherein said fold holding means is a movable slide encircling said flexible polymeric packet.
9. The packet of claim 1 wherein said packet is constructed of at least one flexible polymeric material.
10. The packet of claim 1 wherein said dispersement chamber is used to quantify a dose of said useful liquid before dispersement.
11. The packet of claim 10 wherein said dose quantity may be reduced by transfer back to said reservoir chamber or increased by transfer from said reservoir chamber before dispersement.
12. The packet of claim 1 wherein said flexible polymeric packet and/or said fold holding means is partially and/or fully transparent, translucent, and/or opaque.
13. The packet of claim 1 wherein said flexible polymeric packet and/or said fold holding means bears meaningful communications.
14. The packet of claim 1 wherein said fold holding means is constructed of material that is flexible and/or rigid in part and/or whole and can be used for manipulating liquid transfer within said flexible polymeric packet.
15. A method of resealing a packet according to claim 1 , wherein said method comprises folding said flexible polymeric packet at said fold position so as to seal off said fluidic communication of useful liquid through said restrictive passage.
16. A method of claim 15 further including the step of maintaining said folded packet sealed condition by engaging said fold holding means.
17. A method for reducing sickness and infectious disease in a population, said method comprising;
characterizing said useful liquid of claim 1 as a hand sanitizing fluid;
distributing the resealable packet of claim 1 in a population;
dispensing said fluid from said flexible polymeric packet to skin harboring pathogens; and,
spreading said fluid on said skin sufficient to effectively reduce the number of said pathogens thereon and so reduce the frequency of pathogenic transmission and so reducing sickness and infectious disease among said population.
18. The method of claim 17 further including the step of providing said flexible polymeric packet and/or said holding means of claim 1 with meaningful communications.
