<P>PROBLEM TO BE SOLVED: To reduce the consumption of a resin by making the thickness thinner without causing deformation of a lid element. <P>SOLUTION: The lid element made of a synthetic resin closes the mouth section of a container body. In this case, the peripheral edge section of the top plate of the lid element, which comes into contact with the upper edge of the container body is formed to be thicker, and an inner section from the peripheral edge section is formed to be thinner. Thus, clamping stress when the lid element is fitted is born by the thicker peripheral edge section. <P>COPYRIGHT: (C)2003,JPO |
