Abstract
A sealed, double walled water packet has an inner packet filled with potable water that has a porous outer surface layer containing absorbed water and an outer packet that encloses the inner packet and is connected to the inner layer. The inner packet (which may contain as little as a swallow of water) is connected to the outer packet (both of which can be made as envelopes with tearable sections or peel off corners) along one side or by a string so that the inner packet can be twirled or waved to cause rapid evaporation of water in the porous outer surface layer (which can include hydrogel) to thereby cool the potable water contained inside the inner packet before it is opened.
Claims16
A water packet comprising:
- an inner liquid impermeable packet filled with potable water, said packet being sealed, said inner packet further having a porous outer surface layer containing absorbed water;
- a sealed outer packet that encloses the inner packet and prevents evaporation of said absorbed water contained in the porous outer surface layer of the inner packet until said outer packet is opened and the inner packet is removed from the outer packet;
- and wherein said inner and outer packets are connected one to the other by a connection mechanism.
A water packet comprising:
- a sealed inner liquid impermeable packet filled with potable water;
- at least a portion of an outer surface of said inner packet being covered with a porous material containing absorbed water to form an absorbent outer layer such that rapid evaporation of the absorbed water in said absorbent outer layer will cause said potable water to cool;
- and wherein a sealed outer packet encloses said inner packet to prevent evaporation of said absorbed water contained in the porous outer surface layer of the inner packet until said outer packet is opened and the inner packet is removed from the outer packet.
A single use disposable water packet comprising:
- a sealed liquid impermeable inner packet containing potable water trapped within said inner packet;
- a porous outer surface layer formed on an outer surface of the inner packet retaining an additional amount of water;
- and a sealed outer packet encloses the inner packet trapping said additional amount of water retained in said porous outer surface until said outer packet is opened and said inner packet is removed from the outer packet;
- wherein rapid evaporation of the additional amount of water will cool the potable water trapped within the inner packet before the inner packet is opened.
