JP2000264329A - Heat insulation cup with folded cardboard portion - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve the build-up production capacity to be adhered by adhering an inner layer paper with heat insulation and strength resistance to an outer layer paper and integrating them with a cup body, and mating the integrated cup body with a body to insert the integrated inner layer paper and outer layer paper which is large in strength, repulsive in folding and soft in grip into the body. SOLUTION: In a constitution in which an inner layer paper 4 is interposed between a cup body 2 and an outer layer paper 3, the inner layer paper 4 is punched into various shapes, and the punched portions are folded outwardly and inwardly, or in one direction. Since the inner layer paper 4 between the cup body 2 and the outer layer 3 is formed of the folded inner layer paper 4 itself of cardboard, and large in strength, repulsive in folding, and soft in grip. Even when the inner layer paper is mated with the cup body 1, both insertion and adhesion are small in quantity in a condition where the outer layer paper 3 and the inner layer paper 4 are assembled in a conical shape, the assembly is facilitated, the production capacity is improved, and the cost is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating cup in which an inner layer paper having heat insulating properties and strength resistance is integrated with an outer layer paper by bonding to a cup body, and the resultant is combined with the main body.

[0002]

BACKGROUND OF THE INVENTION Each insulated cup is subject to the strength of the part creating the air layer.

[0003]

(A) The strength of the heat insulating layer is low. (B) Some products have complicated shapes, which depends on production capacity. (C) The cost increases.

[0004]

(A) As shown in FIG. 1, the inner layer paper located between the cup body and the outer layer paper has high strength because the inner layer paper itself is folded. (B) It can be inserted into the conventional cup body in the form of a 3 and 4 cone shown in FIG.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) FIG. 1, FIG. 3 or FIG. 4 shows an embodiment of the invention of claim 1, wherein (4) is located between (2) cup body and (3) outer layer paper in FIG. ) Is an inner layer paper, and the inner layer paper is bent out and in by punching in various forms. (B) As an embodiment, as shown in FIG.

[0006]

(A) The inner layer paper itself shown in FIG. (B) It has a rebounding force of bending and has a soft feeling even when gripped. (C) Even when combining with the cup body, (3)
By placing (4) in a state of being assembled in a conical form, insertion and adhesion are small, and assembly can be made to an objective level, thereby increasing production capacity.
