Abstract
Abstract A bottle used for housing an emergency water ration which is made of high density polyethylene. The material of the bottle is stabilized with UV light. After filling the bottle with water it is sterilized under high pressure conditions in a water bath at a temperature of 120° C. for at least 10 minutes and cooled by means of compressed air. The body of the bottle has a side ratio equal to 1:0.6:0.4 with all sides containing round edges. The bottom surface has a concave configuration. Such a bottle is completely undeformable and may be dropped into the water without damage from a height of 36 m. The water in the bottle has a lifetime longer than 5 years.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
A method for making bottles which are used for storing water which comprises molding high density polyethylene into the shape of bottles, cooling the molded bottles, stabilizing the bottles by exposing them to ultraviolet radiation, introducing water into the bottles, sealing the filled bottles of water with a plug, sterilizing the water by placing the bottles in a water bath where they are heated, under pressure to a temperature of 120° C. cooling the bottles, and encasing the bottles in a plastic foil.
Claim 2
Independent Claim
83 words
A method for making bottles which are used for storing water which comprises molding high density polyethylene into the shape of bottles, cooling the molded bottles, stabilizing the bottles by exposing them to ultraviolet radiation, introducing water into the bottles, sealing the filled bottles of water with a plug, sterilizing the water by placing the bottles in a water bath where they are heated, under pressure to a temperature of 120° C. cooling the bottles, and encasing the bottles in a plastic foil.
Claim 3
Dependent Claim
38 words
The method of claim 1 wherein the moldable high density polyethylene is produced by heating high density granulated polyethylene into a molten state and forcing the molten polyethylene through a die-casting and blowing machine into a bottle mold.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein the molded bottles are rotated when exposed to ultraviolet radiation.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein 95% by volume of the bottle is filled with water, thereby leaving an air cushion within the bottle.
Claim 6
Dependent Claim
18 words
The method of claim 1 wherein said heating at 120° C. is for about 10 to 20 minutes.
Claim 7
Dependent Claim
16 words
The method of claim 5 wherein said cooling is by compressed air blown across the bottles.
