HEAT INSULATING CONTAINER

摘要

PURPOSE: A container having excellent heat insulation that the heat of contents is hardly transmitted even if a user holds any part of the container is provided. CONSTITUTION: A paper cup body(2) is made of a paper coated with a synthetic resin such as polyethylene and so on at both faces of inside and outside having an outwardly curled portion(6) at the rim of an upper opening as firmly winding a floor plate(5) downward of a body cylinder(4) like common paper cups. Also, an outer cylinder(3) is formed with paperboards embossing processed over the whole faces outward. The embossing process has an appropriate prominence and depression. A heat insulating container(1) is produced by integrally forming by attaching the inner face of the upper opening of the outer cylinder(3) with emulsion class adhesive at the outer circumference downward of the outwardly curled portion(6) in the paper cup body(20) by covering the outer cylinder(3).
