Abstract

A heat insulated container (10) consists of a cylindrical body part (11) of which upper part is open and a bottom part which closes the lower part of the body part. The container (10) comprises at least the main body (10A) of the cup inner coated with a polyolefine resin layer and a sleeve (10B) equipped so as to form a gap between the outer peripheral surface of the main body (10A) of the cup and the sleeve (10B). Ribs (13,13') are formed toward the peripheral direction around the outer surface of the body part (11) of the main body (10A) of the cup. The main body (10A) of the cup is formed in a manner that the diameter of the opening of the upper edge of the body (11) is larger than the height of the main body (10A) of the cup. Thus, the heat insulated paper containers having similar shape to a Chinese bowl or an ordinal bowl, having a stability in shape and heat insulation, being easy to hold, having a good design, having a high potential for free expression of printing, and being sanitary and environmental-friendly are realized.

Description

technical field [0001] The present invention relates to a paper heat-insulated container for instant food prepared by pouring hot water, food prepared by heating in a microwave oven, etc., and an apparatus suitable for manufacturing the heat-insulated container and the like. Background technique [0002] Paper-made heat-insulating containers for foods such as instant noodles are well-known containers in which a paper-made heat-insulating member is provided on the outer periphery of a trunk of a paper cup-shaped body to provide heat-insulating properties. As the heat insulating member, a corrugated plate-shaped member in which longitudinally extending convex lines and concave lines are alternately arranged in the circumferential direction of the cup-shaped main body is used. [0003] Japanese Patent Application Laid-Open No. 8-113274 proposes a heat insulating container in which the width of the concave lines of the heat insulating member is smaller than the width of the conv...
