[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic storage container for storing, for example, a liquid detergent or a softening agent.

[0002]

2. Description of the Related Art Conventionally, bottles made of plastics such as polyethylene and polypropylene by blow molding and the like have been frequently used.

On the other hand, recently, from the viewpoint of environmental protection, there has been a demand for reducing the amount of plastic used and separating and collecting these containers.

In order to reduce the amount of plastic used, it is conceivable to reduce the thickness of the storage container. In this case, however, in general, the storage container becomes soft and difficult to grasp or stand alone.

[0005] On the other hand, various types have been proposed in which the periphery of a storage container is covered with a paper box or the like (Jpn.
No. 9-106873, No. 58-94665).

For example, in Japanese Unexamined Utility Model Publication No. 56-150766, a cardboard frame is fixed to a peripheral surface near a filling port of a bottle, and the bottle having a cap fitted to the filling port is separated. The card body is housed in a cardboard box body, the upper end of the box body is fixed to the frame, and a separate cardboard box-shaped top lid is fixed to the box body in a breakable manner.

In Japanese Unexamined Utility Model Publication No. Sho 59-106873, a flange is formed in a substantially annular shape near an inlet of a bottle, the bottle is stored in a cardboard box, and an upper flap provided in the box is provided. Is positioned on the collar, and a separate plastic latch ring is attached to the inlet and then tightened to hold the bottle in the box.

[0008] All of these methods require time and labor for manufacturing and assembling, but are easy to grasp and can stand on their own while plastic parts such as thin-walled containers are thinned.

[0009] Incidentally, as an easy production and assembly,
As shown in Japanese Utility Model Laid-Open Publication No. 58-94665, a bottle is held by a flap on the upper surface of an outer box.

[0010]

[Problem to be solved by the present invention]
In the case of Japanese Patent Application Publication No. 150766, the structure surrounding the bottle is complicated, the number of parts is large, and the production and assembly are troublesome, which is disadvantageous for mass production. There is a problem that the paper box must be torn with a strong force when separating the bottle and the paper box because they are firmly bonded.

In the case of Japanese Utility Model Laid-Open Publication No. Sho 59-106873, since the box is complicated in the developed shape, it takes a lot of time to manufacture and assemble, and a plastic locking ring is used. However, there is a disadvantage that it is difficult to reduce the amount of plastic used.

On the other hand, in the case of Japanese Utility Model Application Laid-Open No. 58-94665, since the bottle must be held by the flap on the upper surface of the outer box, the developed shape of the outer box becomes complicated, and There is a disadvantage that the assembly of the outer box after mounting is also complicated, which is disadvantageous for mass production.

This invention has been devised from the standpoint of environmental protection, which contributes to reducing the amount of plastic used and separating and collecting plastic products. At the time of manufacture, the assembly of the plastic container body and the paper cylinder is simple. Providing a storage container that can be mass-produced, is hard to be deformed even when grasped after assembly, and does not fall out of the container body and paper cylinder part, and can separate them after use after using no extra labor The purpose is to do.

[0014]

In order to solve the above problems SUMMARY OF THE INVENTION The receiving container of the present invention, the base of the cone-shaped portion extending to the mouth portion from the body portion of the container body made of thin plastic and before
At the lower part of the body part, a recess extending in the circumferential direction of the body part
Respectively formed, in each of the upper and lower ends of the paper tube to hold the peripheral surface of the body portion of the container body, the bent piece portion to maintain its bending angle by bending the tip inwardly it
Each, and the container body is inserted into the paper cylinder from the top of the paper cylinder, and the tip of the bent piece portion is inserted into the paper cylinder .
It is characterized in that it is engaged with the concave portion and the concave portion at the lower part of the body portion, respectively .

[0015]

In the storage container according to the present invention, when the paper cylinder is mounted on the container main body, the paper cylinder is covered from above the container main body, so that the mounting (assembly) to the container main body is extremely easy.

After the insertion, the front end of the bent piece bent into the inside of the paper cylinder is locked in the concave portion of the container body.
The paper cylinder does not come off, and the shape of the container body is held by the paper cylinder. Therefore, even when the storage container is in use, the storage container can be firmly grasped.

When the container body is separated from the paper cylinder, the container body is deformed by the pressing force from the side because of the thin plastic, and the tip of the bent piece is easily separated from the concave portion. For this reason, if the container main body is pushed below the paper cylinder, the paper cylinder can be very easily separated from the container main body.
