<P>PROBLEM TO BE SOLVED: To provide a technique that can reduce a liquid amount remained in a pillow-type liquid pack. <P>SOLUTION: A liquid receiver stores liquid therein by hermetically jointing the circumference of a first membrane part and a second membrane part that are formed by a bendable material. A high rigidity part having higher rigidity than other parts is provided at at least one side into which a passage member is inserted between the first membrane part and the second membrane part, and an opposite side of the side into which the passage member is inserted. This suppresses wrinkles especially where the wrinkles are easily generated in the first and second membranes, which can reduce the remained liquid amount generated by the generated wrinkles. <P>COPYRIGHT: (C)2013,JPO&INPIT |
