Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper lid used to cover a cup-shaped container body.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a lid of this type has been widely used to cover a cup-shaped container body 4 containing food such as ice cream, jam and peanut butter. There is. And as a form of this lid 5,
In general, a cylindrical side wall 51 is wound around a disc-shaped so-called "menco" as a top plate 52 and fastened.

[0003]

Since the top plate of the lid described in the prior art is flat as described above, even if the contents such as ice cream are piled up and decorated, the lid is removed from the container body. There was a problem that it could only be seen from above with the item removed, and the decoration effect at the corner could not be fully exerted.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a lid body capable of sufficiently exerting an appealing effect when the contents are piled up and decorated. Especially.

[0005]

In order to achieve the above object, a lid of the present invention is a paper lid attached to a cup-shaped container body, and an upper opening of the container body is opened from the outside. It is characterized by comprising a side wall to be fitted and a top plate attached to the side wall and raised in a dome shape.

It is preferable that the top plate be provided with a window so that the contents can be seen even when the container body is covered.

[0007]

In the lid having the above-described structure, when covered with the container body, the portion of the dome-shaped top plate of the lid serves to form a storage space above the container body.
Also, when the container body has legs such as a paper cup, when the lidded container bodies are stacked, the top plate portion of the lower lid body fits inside the leg portion of the upper container body. Will be crowded.

[0008]

1 is a perspective view showing a lid body according to the present invention together with a container body, FIG. 2 is a half sectional view of the lid body, and FIG. 3 is a half sectional view of the container body.

As can be seen from FIG. 2, the lid 1 is constructed by combining a cylindrical side wall 11 and a dome-shaped top plate 12.

Of these, the top plate 12 is made of a packaging material in which a resin layer such as polypropylene or polyethylene is provided on the inner surface or the inner surface of the paperboard, and as shown in FIG.
It is formed by punching it into a circle in a state where it is put in the surroundings to form a menco 2 and drawing it into a dome shape as shown in FIG. 2 by a paper plate molding machine. Here, as the ruled lines 2a, as shown in FIG. 4, those having different lengths are alternately inserted so that the number thereof increases as it goes to the outer periphery. As a result, when the male and female molds of the paper plate molding machine are used for pressure molding, the ruled line 2a absorbs the shrinkage of the paper, and the top plate 12 has a dome shape with a flat center and an upright peripheral flange portion 12a. Is formed.

The side wall 1 is attached to the top plate 12 thus prepared.
1 is attached by winding and the lid 1 is created. In this case, it is preferable to use a spirally wound paper tube for the side wall 11 in order to keep its thickness constant. The paper tube may be decorated by attaching an aluminum foil to the outside. Then, a ring body obtained by cutting the paper tube into a predetermined length is prepared, and after forming the upper curl portion 11a on the ring body, the top plate 12 is supplied from below the ring to form the flange portion 12a. The lower end of the ring is curled so as to pinch, and the curled inner folded portion is knurled to form a convex portion 11b in a circumferential shape. In addition, this convex portion 11b
Is a step for fitting with an outward curl portion of the container body described below.

The container main body 3 of this embodiment combined with the lid 1 is made of a packaging material in which a resin layer such as polypropylene or polyethylene is provided on the inner or outer surface of the paperboard, and the packaging material is punched into a fan-shaped blank plate. It is formed into a cup shape by the same method as that for producing a conventional paper cup using a cup forming machine. That is, the cross section thereof is as shown in FIG. 3, and after a blank plate is wound and both ends thereof are bonded to form a body portion 31, a bottom plate 32 is wound below the body portion 31 to tighten the leg portions 31a. Form and body 3
It is created by forming the outward curl portion 31b at the upper open end of the No. 1 unit.

The container main body 3 having the above-mentioned structure is filled with contents and covered with the lid 1, and the curl portion 31a of the container main body 3 is fitted over the convex portion 11b of the side wall 11 of the lid 1 so as to fit over them. The sales form is integrated. in this case,
Since the portion of the top plate 12 of the lid 1 is raised like a dome, the raised contents can be stored. Further, when the container bodies 3 to which the lid body 1 is attached are stacked, as shown in FIG. 5, the top plate 1 in the lower lid body 1 is stacked.
Since the portion 2 is fitted in the leg portion 31a of the container body 3 on the upper side, the lateral displacement during transportation or display is prevented.

As another form, a window hole may be provided on the top plate 12 of the lid 1 so that the contents can be seen from the top when the container body 3 is covered. That is, the window hole may be punched at the same time as the punch 2 that serves as the top plate 12 is punched. In addition,
In this case, it is preferable in hygiene that a transparent film or the like is attached from the inside if necessary.

Although the convex portion 11b on the inner surface of the side wall 11 of the lid 1 is not always necessary, a strong fitting force can be obtained when the container body 2 has an outwardly projecting portion such as the curl portion 21a. It is convenient.

The container body is not limited to the ordinary paper cup mentioned in the above embodiment, but a cup-shaped container made of other material such as synthetic resin may be used.
If the leg portions as described above are provided, the stacking property is improved. Further, if an outwardly projecting portion is provided on the upper part of the container body, the use of a lid body provided with a convex portion on the inner surface of the side wall enables firm fitting with this lid body.

In the above, the embodiment has been described with respect to the lid body having a circular outer shape, but the lid body of the present invention is, for example, a quadrangular or triangular cup-shaped container body with rounded corners. It is also possible to have a covering shape. In this case, each corner has a rounded shape, and a square or triangular shaped menco is formed by inserting radial pressing rules at the required portions of the corners, and by drawing this, a dome-shaped top plate is formed. After that, by winding the side wall around the top plate, it is possible to form a lid body having a quadrangular or triangular outer shape.

[0018]

As described above, the lid of the present invention is
Since it has a dome-shaped raised top plate, it is possible to raise it higher than the upper edge of the container body when decorating the contents, so when the lid is opened, the decoration can be seen from the side, The appeal effect can be sufficiently exerted. Further, by providing the lid with the window hole, the decoration can be seen from the outside even when the lid is covered, which is effective in promoting sales in stores and the like.

When a container body having a leg portion such as a paper cup is used as the container body, the top plate portion of the lower lid body is inside the leg portion of the upper container body when the lids are stacked. Since they are fitted in each other and the lateral displacement between them is prevented, the stackability is improved.
