Abstract

PROBLEM TO BE SOLVED: To provide a cup shape container made of paper which wastes no material and has a neat and good appearance because the butt part of both side edges of a heat insulating cover is not easily seen. SOLUTION: This cup shape container made of paper comprises a cup shape container main body 1 mainly made of paper and a heat insulating cover 2 for covering the outer peripheral face of the main body 1. The corrugated board paper having vertical ridges 3 and grooves 4 lines alternately, and each ridge 3 meanders relative to the center axis line is used as a material for the cover 2. The corrugated paper, before the same covers the outer peripheral face of the main body 1, is shaped into a rectangle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup-shaped container made of paper having a high heat insulating effect and used as a container for instant noodles, hot coffee and the like.

[0002]

2. Description of the Related Art In recent years, cup-type containers such as instant noodles and hot coffee have been shifting from those made of foamed plastics to those made of paper due to problems such as disposal during disposal.

Conventionally, as a cup-shaped container made of paper, as shown in FIG. 5, a cup-shaped container main body 10 mainly made of paper, and a heat insulating cover 11 put on the outer peripheral surface of the container main body 10 are provided. (JP-A-9-13)
No. 2224).

As shown in FIG. 7, a so-called single-sided cardboard paper in which a corrugated paperboard 13 and a liner paper 12 are adhered to each other is used as a material of the heat insulating cover 11, as shown in FIG. The paper 12 is bonded to the outer peripheral surface of the cup-shaped container body 10 with the paper 12 facing outward.

Since the cup-shaped container main body 10 has a shape that spreads upward, the heat-insulating cover 11 attached to the outer peripheral surface is formed in a fan-shaped shape as shown in FIG. I have.

If the single-sided corrugated cardboard is formed in a fan shape, the steps are cut diagonally at both side edges. Therefore, when the tubular heat insulating cover 11 is used, the diagonal steps of the cut corrugated paperboard 13 are cut. However, there is a problem in that a gap appears at a butt portion between both side edges of the heat insulating cover, which impairs appearance and aesthetic appearance.

Further, when the material for forming the heat insulating cover 11 is formed in a fan shape, the material is larger than the height of the cup-shaped container body 10 by the amount of bending in the fan shape.
There was also a problem that materials were wasted.

[0008] Therefore, the present invention has no waste in materials,
In addition, it is an object of the present invention to provide a cup-shaped container which is clean and has a good appearance without abutting portions on both side edges of the heat insulating cover.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a paper comprising a cup-shaped container body mainly made of paper and a heat insulating cover which is put on the outer peripheral surface of the container body. In a cup-shaped container made of, as a material of the heat insulating cover, a corrugated paperboard in which longitudinal ridges and grooves are alternately arranged and each ridge is meandering with respect to a central axis is used, and the outer periphery of the container body is used. The shape of the corrugated paperboard before being put on the surface is a rectangle.

When the corrugated paperboard before being covered on the outer peripheral surface of the container body is made rectangular, the corrugated paperboard is formed into a cylindrical shape by abutting the both side edges so as to slightly overlap each other. , The overlapping portions of both side edges are inconspicuous, and the appearance is good.

By using corrugated paperboard in which longitudinal ridges and grooves are alternately arranged as a material of the heat-insulating cover, the upper part can be freely expanded in a state where the both sides are abutted to form a cylinder. , Can be placed on a cup-shaped container body whose upper part expands.

Further, the corrugated paperboard has a shape in which longitudinal ridges and grooves are alternately arranged, and each ridge has a meandering shape with respect to the central axis, so that heat insulation is good, strength is high, and both side edges are provided. When they are formed into a tubular shape by abutting each other, the longitudinal ridges and the grooves are fitted and temporarily fixed at the overlapping portions of both side edges, so that it is easy to form the tubular shape.

[0013]

FIG. 1 shows an embodiment of a cup-shaped container according to the present invention.

The cup-shaped container according to the present invention comprises a cup-shaped container main body 1 mainly made of paper, and a heat insulating cover 2 placed on the outer peripheral surface of the container main body 1.

The container body 1 and the heat-insulating cover 2 are bonded together with an adhesive.

As the material of the heat insulating cover 2, corrugated paperboard in which longitudinal ridges 3 and grooves 4 are alternately arranged is used.
As shown in the enlarged view of FIG. 3, each ridge 3 meanders with respect to the central axis, and the strength in the height direction is increased. And
The shape of the corrugated paperboard before being covered on the outer peripheral surface of the container body 1 is rectangular as shown in FIG.

The corrugated paperboard is 10 cm per 10 cm.
Has 15 ridges 3, and the height of the ridges 3 is about 3 mm
The meandering bent portion formed on the ridge portion 3 preferably has 20 to 28 per 10 cm in the length direction of the ridge portion 3.

As described above, the corrugated paperboard before being put on the outer peripheral surface of the container body 1 is made to have a rectangular shape. Since the directions of the ridges 3 of the corrugated paperboard coincide with each other, the overlapping portions of both side edges are not conspicuous, the appearance is good, and the material is not wasted.

As a material for the heat insulating cover 2,
By using corrugated paperboard in which the longitudinal ridges 3 and the grooves 4 are alternately arranged, the upper side is freely expanded in a state in which both sides are abutted and formed into a cylindrical shape, so that the cup-shaped container body 1 is expanded upward. Can be put on.

Further, since the corrugated paperboard has a shape in which longitudinal ridges 3 and grooves 4 are alternately arranged and each ridge 3 meanders with respect to the center axis, the heat insulating effect is good and the strength is high. ,
When forming the cylindrical shape by abutting both side edges, the longitudinal ridges and the groove portions are fitted and temporarily fixed at the overlapping portions of the both side edges, so that the cylindrical shape is easily formed.

[0021]

As described above, according to the present invention, it is possible to obtain a cup-shaped container which is made of the least amount of material and in which the abutting portions of the both side edges of the heat insulating cover are inconspicuous.
