[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup-shaped container, and more particularly, to a cup-shaped container having a cup-shaped opening having an upper opening and a circular lid closing the upper opening of the container. It relates to a cup-shaped container.

[0002]

2. Description of the Related Art Cup-shaped containers are widely used to supply various kinds of frozen desserts and foods. Such containers are
A fan-shaped sheet material mainly composed of paper is wound into a cup and molded, and the bottom opening is closed by a bottom plate, and a circular lid is attached so as to close the top opening. It is.

[0003]

[Problem to be Solved by the Invention] When filling such a cup-shaped container with frozen desserts and various foods for distribution, at the distribution stage or at the point of sale at the store, the lid for closing the upper opening is removed. There is a possibility that mischief or an accident may occur, such as removing the internal product or inserting a foreign substance therein.

[0004] Such mischief or accident cannot be prevented by a cup-shaped container in which the lid is formed of a circular paperboard and the paperboard is attached to an upper opening. That is, once removed, it must not be possible to mount it again. Therefore, an aluminum foil laminated with a synthetic resin film is directly sealed to the periphery of the upper opening.

However, there has been a problem that a lid made of a synthetic resin, particularly a lid made of a molded body, cannot have the above-described function for preventing tampering. That is, the conventional synthetic resin lid is merely covered, and has no function of preventing mischief. Therefore, when using such a lid,
It has to be used in combination with other sealing means, and there is a problem that the cost increases.

The present invention has been made in view of such a problem, and provides a cup-shaped container having a lid formed into a predetermined shape and having a function of preventing mischief. It is intended to do so.

[0007]

According to the present invention, there is provided a container body which is made of paper as a main material, is formed in a cup shape and has an opening at an upper portion, and a synthetic resin molded body which is formed at an upper opening of the container body. And a curl portion formed by winding the opening edge of the container body outward and forming an engagement groove formed on the outer peripheral side of the lid and opened downward. A skirt portion, which is thinner than the outer peripheral wall, is connected to a tip portion of an outer peripheral wall constituting an outer peripheral side of the engaging groove of the lid, and the curl portion is formed from the engaging groove. The skirt is obliquely squeezed while the curl is engaged in the engagement groove so as to be detachable and prevent insertion of the curl from the outside into the engagement groove. A cup-shaped container characterized by closing the engagement groove It is intended to.

[0008]

Accordingly, the container body is filled with the contents, and a lid is attached so as to cover the upper opening, and the engaging groove on the outer peripheral side of the lid is wound around the opening edge of the container body to the outside. The engagement groove is closed and sealed by narrowing the thin skirt portion at the outer edge of the engagement groove of the lid. Therefore, if the lid is removed during the distribution stage or at the time of selling the product, the curled portion comes off the engagement groove of the lid through the narrowed skirt portion, and is resealed. Can not be done.

[0009]

FIG. 1 shows a cup-shaped container according to an embodiment of the present invention. The cup-shaped container includes a container body 10 wound by a fan-shaped sheet-shaped material mainly composed of paper. And a lid 11 for closing the upper opening 12 of the container body 10.

As shown in FIG. 5, the lower end of the body of the container body 10 is folded inward to form a folded portion 15, and a peripheral wall portion 17 on the outer peripheral side of the bottom plate 16 is combined with the folded portion 15. The container body 10 is sandwiched by the body part. As a result, the bottom plate 16 closes the bottom of the container body 10. In addition, the container main body 10 has a curl 20
Is formed.

On the other hand, as shown in FIGS. 2 to 4, the lid 11 is made of a synthetic resin molded body, and an engagement groove 23 extending in the circumferential direction and having a U-shaped cross section is formed in an outer peripheral portion thereof. Is formed. On the upper surface of the engagement groove 23, a rib 24 extending in the circumferential direction is formed as shown in FIGS. As shown in FIGS. 3 and 4, vertical ribs 25 are formed intermittently at intervals of 30 ° inside the engagement groove 23.

A thin skirt portion 26 is formed on the outer peripheral edge of the engaging groove 23 so as to hang down. Here, the thickness of the skirt 26 is 0.2
.About.0.4 mm.
It is possible to narrow down at a low temperature of 00 to 150 ° C.

In the above configuration, the container body 10 is filled with frozen desserts and other various foods, and the lid 11 is attached so as to cover the upper opening 12. As shown in FIG. 5, the curl portion 20 on the outer peripheral side of the container body 10 is received in the engagement groove 23 of the lid 11, whereby the upper opening 12 is closed by the lid 11.

Further, the cup-shaped container of this embodiment uses a narrowing jig 30 shown in FIG.
The skirt portion 26 is heated at a low temperature of 00 to 150 ° C.
As shown in FIG. 7, the skirt 26 is inclined inward, and the lower opening of the engaging groove 23 on the outer peripheral side of the lid 11 is closed.

As described above, in the container according to the present embodiment, the thin skirt portion 26 formed on the outer peripheral edge portion of the engagement groove 23 of the lid 11 is narrowed by the narrowing jig 30. Thus, the opened portion of the engagement groove 23 is closed. Therefore, when the lid 11 is opened, the curl portion 20 of the container body 10 is detached from the engagement groove 23 while pushing and expanding the skirt portion 26.

However, when the container body 10 is closed once again by the lid 11 after being opened, the thin skirt portion 26 hits the curl portion 20 of the container body 10 and is pushed into the engaging groove 23 by the curl portion 20. Will be able to
That is, according to such a container, it becomes very difficult to make the skirt portion 26 in the same state as before opening when resealing. Therefore, when the lid 11 is once opened and resealed, it can be visually confirmed that the lid 11 is clearly different from the unopened one.

Accordingly, by providing such a skirt portion 26, it is possible to more reliably prevent the contents from being removed at the distribution stage, or to prevent mischief such as mixing of foreign matter during the sale of the product. Become. That is, the function of preventing mischief can be imparted to the cup-shaped container by narrowing down the skirt portion 26 provided on the outer peripheral edge portion of the engaging groove 23 of the lid 11. Moreover, since no separate sealing means is required, the packaging cost does not increase.

[0018]

As described above, according to the present invention, the main body is made of paper, formed into a cup shape and has an opening at the upper part, and a synthetic resin molded body, and the upper opening of the container main body is formed. And a curl portion formed by winding the opening edge of the container body outward and engaging an engagement groove formed on the outer peripheral side of the lid body and opened downward with the curl portion. In addition, a skirt portion thinner than the outer peripheral wall is continuously provided at the tip of the outer peripheral wall which constitutes the outer peripheral side of the engaging groove of the lid, and the curl portion can be detached from the engaging groove so as to be engaged from the outside. In order to prevent the insertion of the curl portion into the mating groove, the skirt portion is obliquely squeezed while the curl portion is engaged in the engaging groove to close the engaging groove.

Therefore, when a force is applied to the container body so as to detach the cover to remove the cover when opening the container, the container body engaged in the engagement groove of the cover is removed. The curl part gets over the diagonal skirt part at the tip on the outer peripheral side of the engagement groove, and comes off from the engagement groove. Therefore, even if there is a skirt portion, the opening operation can be performed smoothly. When the upper opening of the container body is to be resealed with the lid after being once opened, the curl portion of the container body comes into contact with the diagonal skirt portion at the tip of the outer peripheral wall constituting the outer peripheral side of the engagement groove of the lid. As a result, insertion of the curled portion of the container body into the engagement groove of the lid is prevented. When the curl of the container body is forcibly inserted into the engagement groove of the lid,
The skirt portion is forcibly inserted into the engagement groove in a state of being irregularly deformed, resulting in an unsightly state.
That is, if the upper opening of the container body is to be resealed with the lid after being once opened, the skirt portion narrowed down diagonally enters the engagement groove, and as a result, the skirt portion reopens in the same state as before resealing. It will prevent the seal. Therefore, once opened, the shape when resealed is greatly different from the state before the first opening, and it is possible to provide a cup-shaped container having a function of preventing tampering.
