Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a container made of thermoplastic synthetic resin, such as polypropylene resin or polyethylene resin.

<Prior art> This type of container is often used as a daily necessities such as waste containers, but the material used is thermoplastic synthetic resin such as the above-mentioned polypropylene resin, which cannot be bonded to rubber substances, such as natural rubber or synthetic rubber. Therefore, in order to form an attached part such as a handle on a container made of polypropylene resin or polyethylene resin, the container body and the attached part are integrally molded from the same material.

<Problem that the invention aims to solve> As described above, in conventional containers, the attached parts cannot be separately made of rubber material, so the shape is fixed for the design, and the attached parts, such as the handle part, cannot be made separately. The problem was that it was not possible to use the most suitable rubber material.

<Means for Solving the Problems> In the present invention, a through hole 12 is pre-drilled in the attachment part of the container body 1, and the attachment part such as the handle 2 to be attached to the container body 1 is provided with a through hole 12 in advance. Above through hole 1
A small hole 5 communicating with the hole 2 is recessed.

A locking ring 6 is embedded in the small hole 5, and a through hole 7 is provided in the locking ring 6 so as to open within the small hole.

The attached member 2 is brought into close contact with the outer peripheral surface of the container body 1, and a stop pin 11 is press-fitted from the inside of the container body 1 into the small hole 5 of the attached member 2 through the through hole 12. is made slightly larger than the diameter of the through hole 7 of the locking ring 6, and is press-fitted through the through hole 7 to the depth of the small hole 5. Therefore, it is desirable that the through hole 7 of the locking ring 6 has a radial cut groove 8 formed on the edge of the hole, thereby forming a locking piece 9.

<Function> Since the container of the present invention is as described above, the stop pin 11 press-fitted from the through-hole 12 of the container body 1 into the small hole 6 of the attached member 2 is press-fitted through the through-hole 7. The edge of the through hole 7 is pressed and bent toward the back of the small hole, thereby being locked in a manner that cannot be removed.
If the locking piece 9 is provided on the edge of the through hole 7 as described above, the hole edge can be easily bent by the stop pin 11, and the bent length of the locking piece 9 can be adjusted as shown in FIG. As shown, since it is longer, the locking effect can be increased.

<Example> The proposed container will be explained below with reference to the attached drawings.
FIG. 1 is a perspective view of a waste container that is an embodiment of the container of the present invention. This waste container includes a container body 1 with an opening on the top, which is made of, for example, polypropylene resin or polyethylene resin, and a body part on both sides of the container body 1. The container body 1 is made up of an attached member, such as a handle 2, and an annular cover 3 attached to the opening edge of the container body 1, if desired.

The handle 2 is made of a material that cannot be bonded to the container body 1, and in the embodiment, it is cast from a synthetic rubber material.

The handle 2 has a joint surface 4 formed so as to be in close contact with the body surface of the container body 1, as shown in FIG.
A suitable number of small holes 5 are opened in this joint surface 4 and are bored perpendicularly to the joint surface 4 as shown in FIG. As shown in FIG. 4, this locking ring 6 has a through hole 7 formed in the center and a locking piece 9 divided by radial grooves 8 on the edge of the through hole 7. are doing.

The locking ring 6 has its peripheral edge 10 embedded in the hole wall of the small hole 5 so that the through hole 7 is connected to the small hole 5.
Preferably, the locking piece 9 is inclined toward the back of the opening of the small hole 5, as shown by the chain line in FIG. The locking ring 6 may be embedded in the handle 2 in a mold when the handle 2 is cast, and when the joint surface 4 of the handle 2 is a curved surface as in the embodiment, the small hole 5 It goes without saying that the holes are drilled at right angles to the cutting line.

The handle 2 is attached to the container body 1 as shown in FIG.
For this purpose, a through hole 12 is provided in the container body 1, and the stop pin 11 is inserted through the through hole 12 into the small hole 5 of the handle 2. It will be done.

The locking pin 11 has a shaft diameter that is larger than that of the locking ring 6.
The size is slightly larger than the diameter of the through hole 7,
Therefore, when the locking pin 11 is press-fitted into the small hole 5 of the handle 2, the locking piece 9 formed on the hole wall of the small hole 5 is inserted into the sixth hole.
As shown by the solid line in the figure, the stop pin 1 is bent toward the back of the hole.
The shaft portion of No. 1 is locked so that it cannot be pulled out.

<Effect of the invention> In this way, the container of the present invention can be attached to the container body 1 by embedding the locking ring 6 in advance in the attached members such as the handle 2, and engaging the locking pin 11 with the locking ring 6. Since the parts are fixed, there is an advantage that no adhesive means is required for fixing the accessory parts to the container body 1, and it is also possible to select different types of accessory parts to the container body 1 of the same type. It also has the effect that it is easy to diversify product types because it can be used in various ways.
