<p><P>PROBLEM TO BE SOLVED: To provide a wall body structure for a container and a method for manufacturing the container capable of manufacturing a container which is reduced in weight, at higher productivity than a conventional method. <P>SOLUTION: Since the weight of the container 10 is reduced by light-weight holes 21F and 22F and thin wall portions 21B and 22B, and also the thin wall portions 21B and 22B can be formed into a core-back shape by a resin molding die 50 which can be used to form body wall portions 21A and 22A having the light-weight holes 21F and 22F in the first and the second sidewalls 21 and 22 in accordance with the wall body structure and the method for manufacturing the container 10, it becomes unnecessary to carry out conventional work of sticking a seat and it becomes possible to manufacture the container 10 at the higher productivity than the conventional method. Moreover, it becomes unnecessary to use high fluidity resin for forming the container 10, and therefore, the problem of the decrease in impact resistance or the like is dissolved. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
