Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bottomed cylindrical paper container used as a storage box for food and the like.

[0002]

[Prior Art]

 In a conventional paper container, for example, as shown in FIG. 3, a container body 22 and a lid body 24 having the same diameter are formed in a tea tube shape, and the lid body 24 is fitted and capped in the opening of the container body 22. Which is blocked by that (see Japanese Utility Model Laid-Open No. 62-179976) or a pull-up type container 22 'as shown in FIG. 4, which is provided separately after the one end lid 24'a is opened. Some of them are closed by a lid 24'b (see Japanese Patent Laid-Open No. 4-57736).

However, in the tea-cylinder-shaped paper container, the container body 22 and the lid body 24 have to be manufactured separately, and in addition, it is necessary to have a high degree of precision for surely fitting them. However, it is not suitable for long-term storage items because the container body 22 and the lid body 24 are easily detached despite the time and effort required.

In addition, although the pull-top type container has sufficient sealing property, since the lid 24′a is made of another material such as metal such as aluminum and tin plate, the lid 24′a is made of a paper tube and a metal. It was difficult to fasten and fasten the peripheral edge portion 29 'of the opening, and there was a processing problem when discarding the container including the fastened metal portion.

Therefore, recently, as shown in FIG. 5, the opening peripheral edge portion 29 "of the container body 22" is arranged so that the lid body 24 "is engaged with the opening portion 23" of the container body 22 ". A paper container that has been curled toward the outer wall surface 25 "side of the main body 22" so that the curl rim portion 34 "acts as a locking portion of the lid body 24" (Jitsuko Sho 61-12228). , See Japanese Utility Model Laid-Open No. 62-118 010).

[0006]

However, in the case where the opening peripheral edge portion 29 "of the container body 22" is curled toward the outer wall surface 25 ", as shown in FIG. Since the back side 33 "side of the paper material forming the container body 22" is exposed, the color of the outer wall surface 25 "of the container body 22" and the curl lip 34 "are different, and the curl lip is also different. Even the seam line 35 "of the paper material was exposed in the part 34", and the appearance was not good, and the container was poorly designed.

Further, in the above-mentioned container, the end portion 32 ″ of the curl rim portion 34 ″ is located on the outer wall surface 25 ″ side of the container body 22 ″, so if it is used as a locking portion for a long period of time, it will roll up. As a result, not only does it look bad, but it becomes difficult to attach / detach the lid 24 "itself. If this happens, the decline in product value will inevitably become a problem.

In view of the above problems, the present invention provides a paper container that can be manufactured and disposed of in a simple process so that the lid is securely and firmly engaged, and the design is more beautiful. The challenge is to provide.

[0009]

[Means for Solving the Problems]

 The present invention takes the following technical means in order to achieve the above object.

That is, a paper having a bottomed cylindrical paper container body 2 covered with a decorative paper 5 and a lid body 4 detachably engaged with an opening 3 of the container body 2. In the container, the inner peripheral surface 12 of the opening peripheral portion 9 of the container main body 2 is formed by winding 13 the main body 2 inward, and the outer peripheral surface 16 is a step portion that bulges outward. It is characterized in that it is formed by surrounding 17 and an engaging portion 11 that is detachable from the step 17 is provided on the inner surface of the lid 4.

[0011]

[Action]

 Since the outer peripheral surface 16 of the opening peripheral portion 9 of the container body 2 of the paper container covered with the decorative paper 5 according to the present invention is provided with the step portion 17 bulging outward, By locking the engaging portion 11 provided on the lid body 4 to 17, the paper container is securely and firmly closed.

Furthermore, since the inner peripheral surface 12 of the opening peripheral edge portion 9 is formed by winding 14 the main body 2 inward, the back surface 13 and the joint line 15 of the paper material 1 are not exposed. , It becomes a beautiful paper container covered with decorative paper.

[0013]

【Example】

 An embodiment of the paper container of the present invention will be described below with reference to the drawings.

The paper container of the present invention is used, for example, for storing a filter type coffee pack, food and drink such as dry matter (shiitake mushrooms), and as shown in FIG. A bottomed cylindrical container body 2 formed by spirally winding laminated paper materials 1 and a lid body 4 detachably engaged with an opening 3 of the container body 2. The container body 2 is further covered with a part or the whole of the decorative paper 5 having various colors and designs on its surface.

As the material of the lid body 4, the paper material 1 may be used as in the case of the main body 2. However, when ordinary thermoplastic synthetic resin such as polyethylene, vinyl chloride or polypropylene is used, moisture resistance and gas barrier property are obtained. And so on.

The lid 4 is composed of a top plate 6 and side walls 7, and a container 8 is provided on the peripheral edge portion 8 of the top plate 6 so that the opening 3 of the container body 2 is closed when crowned. A bulging portion 10 with which the opening peripheral edge portion 9 of the main body 2 is abutted and locked is formed, and a rib-shaped engaging portion 11 is formed on the inner peripheral surface of the side wall 7 so as to project therefrom.

Further, it is of course possible that the lower end of the side wall 7 of the lid body 4 is provided with a flange portion for opening the lid body 4 or the like.

The engaging portions 11 provided on the inner surface of the side wall 7 may be provided so as to project at several places at regular intervals, or may be provided around the entire inner circumference of the side wall 7.

In the paper container of the present invention, the inner peripheral surface 12 of the opening peripheral portion 9 of the container body 2 is, as shown in FIGS. 1 and 2, together with the coated decorative paper 5, the inner wall surface of the container body 2. Curl processing (called curl) 14 is applied toward the 13 side.

By this inner surface curl treatment 14, the inner wall surface 13 of the container body 2, that is, the back surface paper of the paper material 1 and the joint line 15 are not exposed, and a container having a very beautiful appearance is obtained.

Further, on the outer peripheral surface 16 of the opening peripheral edge portion 9, a step portion 17 which bulges outward is circumferentially provided. Therefore, the lid body 4 is firmly fitted onto the opening peripheral edge portion 9 of the container body 2 by the engagement portion 11 provided on the step portion 17 and the inner peripheral surface of the side wall 7 of the lid body 4, and The opening 3 of 2 is surely closed.

The curl treatment 14 may be carried out by covering the decorative paper 5 and then performing normal press processing on the decorative paper 5 or the like. The opening peripheral edge portion 9 of the container main body 2 may be provided in such a position, and the nail pieces may be pressed all at once from the surroundings, or the pressure may be gradually pressed partially. Further, the pressing process performed at the time of the curl process may be performed again, and the step 17 may be circumferentially provided by pressing.

In the present embodiment, the cylindrical container has been described, but it is needless to say that the container may have another shape, for example, an elliptical cross section or a polygonal shape with curved corners, and the peripheral edge of the opening is as described above. The shape is not particularly limited as long as the inner surface is curled. Further, in the above-described embodiment, the container wound in a spiral shape has been described, but it goes without saying that a container simply wound may be used.
