<p><P>PROBLEM TO BE SOLVED: To solve the problem that a conventional cartridge container (drinking water container) can hardly be folded up in a flat shape after an inner fluid is discharged. <P>SOLUTION: A concave-convex pattern 9, 11 are formed on the upper half area 8 and the lower half area 10 of each of opposing two side plates 3 among four side plates composing the drinking water container 1 so that the center part in the up-and-down direction can be folded in a valley shape horizontally and inward. A predetermined concave-convex pattern 13, 14, 15, 16 are formed on the remained two opposing side plates 4 so that the side plates can be folded in a valley shape in the diagonal 12 direction and inward. The drinking water container 1 is naturally folded by atmospheric pressure being accompanied with discharging of the stored fluid and the container is folded up in an almost flat shape when the container becomes empty. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
