LIQUID VESSEL USING FOAMED RESIN SHEET

Title:

LIQUID VESSEL USING FOAMED RESIN SHEET

Document Type and Number:

Japanese Patent JPH08118499

Kind Code:

A

Abstract:

PURPOSE: To provide a liquid vessel using a foamed resin sheet of the structure in which the thickness of the connecting part of both connecting sides of the sheet is made substantially the same as that of the part except the connecting part even by using the sheet having roughly a specific % of the expansion coefficient and the cut ends of both the connecting sides are not disposed inside the vessel.

CONSTITUTION: The expansion coefficient of foaming of a foamed resin sheet 10 is about 300%. Either one connecting side 11 of the sheet 10 is folded, the other connecting side 13 of the sheet 10 is superposed on the side 11 of the sheet 10 becoming double by the molding to be triple. The triple superposed part is heated and pressurized until the thickness becomes substantially the same as the thickness of the other part of the sheet 10 to be bonded.
