Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cup container with a handle used for cup ramen, cup soup and the like.
[0002]
[Prior art]
As is well known, as a cup ramen, cup soup, etc., a cup-shaped container body made of a synthetic resin such as polypropylene and having an upper end opened and a flange formed around the opening, and the flange of the container body A container made of a lid that is thermally bonded to the container and seals the opening of the container body is used.
[0003]
[Problems to be solved by the invention]
This type of container is not very good in heat insulation because the container body is made of synthetic resin, and the outer peripheral surface of the container body becomes hot due to the heat of the hot water poured into the container body, and it is hot and cannot be held in hand. There is. As means for solving this, for example, it is conceivable to form a handle on the container body or to use paper as the material of the container body.
[0004]
However, in the former case, the cost of the mold is increased and it takes time to form the container, so the problem is that the container is greatly increased in cost, and the handle part becomes an obstacle and the container cannot be stacked. There is a problem that costs increase.
[0005]
In the latter case, the peripheral edge of the opening of the container body is curled so that the adhesion area with the lid is small, and the buckling strength of the peripheral wall of the container body is low, so the pressure at the time of adhesion of the lid is low. There is a problem that it cannot be enlarged and the sealing performance is poor.
[0006]
In addition, when the container body is made of synthetic resin, in order to make a painting for makeup on the outer peripheral surface, it is necessary to use a costly method such as painting at the same time as molding, and the manufacturing cost is high. was there.
[0007]
The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide good heat insulation at the part that is touched during use, low manufacturing costs and logistics costs, and good sealing performance. It is to provide a cup container.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a container with a handle according to the present invention comprises a cup-shaped container body made of a synthetic resin, having an upper end opened and a flange formed around the opening, and paper having moderate rigidity. And is formed so as to cover the outer peripheral surface of the container main body and along the outer peripheral surface, and is thermally bonded to a flange of the container main body, and a flange of the container main body. It is characterized by comprising a lid that seals the opening.
[0009]
In order to reduce the manufacturing cost, it is preferable that the cylindrical body is made of a single sheet member, and the handle portion forming piece is formed by a slit that penetrates the cylindrical body in its thickness direction.
[0010]
Further, the cylindrical body may be bonded to the container main body in order to make it difficult for the cylindrical body to come off from the container main body.
[0011]
In this case, the cylindrical body is preferably spot-bonded to the container main body so that the container main body and the cylindrical body can be separated and discarded.
[0012]
In order to facilitate the production, a thermal adhesive layer may be provided on the inner surface of the cylindrical body, and the cylindrical body may be thermally bonded to the container body via the thermal adhesive layer.
[0013]
Further, in order to make it difficult for the container main body to come out of the cylindrical body, the lower end portion of the cylindrical body may be bent so as to wind the lower edge of the peripheral wall of the container main body, or the peripheral edge portion of the flange An extending portion may be formed downward, and an insertion portion for inserting the upper end portion of the cylindrical body may be formed between the extending portion and the outer peripheral surface of the container body. .
[0014]
Further, in order to eliminate the need for adhesion between the cylindrical body and the container main body, the cylindrical body is pressed by pressing the inner surface of the cylindrical body outward on the outer peripheral surface of the container main body. You may provide the protrusion which latches on the said container main body.
[0015]
