However, in recent years, the separation and collection of garbage and the reuse of resources have been widely performed due to the increase in the recycling movement of resources. Therefore, in the case of a product having such a dissimilar material member as described above, it is necessary to separate the container body and the dissimilar material member when discarding it. However, it is difficult to separate the rigidly attached dissimilar material members as described above, and as a result, there is a problem that the collected containers are not used as a resource.

On the other hand, in the related art, as in the container disclosed in Japanese Utility Model Application Laid-Open No. 7-43124, a container having a separate bottom member attached to the bottom of the container body,
There has been proposed a container in which a bottom member is removable by providing a recess in the vertical direction and inserting a plate-shaped member in this portion.

However, in such a container, the bottom member is mounted by engaging the protrusion of the inner surface with the circumferential groove of the container main body, and after applying a force to the protrusion once by the plate-shaped member. In addition, a force must be applied in the direction of separating the bottom member from the container body, that is, in the vertical direction, and when the user holds the container body to perform the work, it is difficult to remove the bottom member, and if too much force is applied, the bottom member will not be removed. There was a possibility of skipping.

Therefore, an object of the present invention is to provide a dissimilar material-assembled container which can be easily removed when disposing of a dissimilar material member even if it is attached with a certain strength. is there.

[0007]

In order to solve the above problems, a container with a dissimilar material member according to the present invention comprises a container body and a dissimilar material formed of a dissimilar material and attached to a shoulder portion or a bottom portion of the container body. A dissimilar material assembly container having a member, wherein a space is formed between the container body and the dissimilar material member to allow insertion of a plate member, and a part of the dissimilar material member adjacent to the space is formed.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of a container with a dissimilar material member according to the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of the same container, FIG. 2 is a partial plan sectional view of the same container, FIG. 3 is a front view of a shoulder portion of the same container, FIG. 4 is a partial side sectional view of the same container, and FIG. It is a figure explaining operation at the time of removing a shoulder member.

As shown in FIGS. 1 to 4, the dissimilar material member-assembled container (hereinafter, simply referred to as container) A according to this embodiment is
This is a container in which a shoulder member 2 is attached to a shoulder portion 12 of a container body 1 for holding contents such as a cosmetic material, and a bottom member 3 is attached to a bottom portion 13. The container body 1 is a cylindrical body made of glass and having an oval cross section, and a thin cylindrical neck portion 11 is provided at the center of a shoulder portion 12 on the upper portion of the container body 1. A screw 11a is formed on the outer periphery of the neck portion 11 so that a lid (not shown) can be screwed.
Further, a lip 11b that engages with a shoulder member 2 described later is formed on the base side of the neck portion 11. A concave portion 12a extending from the outer edge of the container body 1 toward the neck portion 11 is formed on the upper surface of the shoulder portion 12, and a space 4a into which a plate member 5 such as a coin (shown by a two-dot chain line in FIG. 4) can be inserted is formed. It is formed.

A recess 13a extending from the outer edge of the container toward the center of the container is formed in the bottom 13 of the lower part of the container body 1, and a space 4b into which the plate member 5 can be inserted is formed similarly to the shoulder 12. The concave portion 13a is lowered toward the center of the container, and an inclined portion 13c is formed here. Further, a step portion for assembling the bottom member 13 is formed, and a lip 13b for attaching the bottom member 3 is formed on the peripheral side surface of this step portion.

Unlike the container body 1, the shoulder member 2 is a member made of synthetic resin, has the same shape and size as the cross section of the container body 1, and has a skirt 2a provided upright on the peripheral edge thereof. Further, a hole 2b through which the neck portion 11 can be inserted when attached to the container body 1 is formed in the center of the shoulder member 2.

On the lower surface of the shoulder member 2, on the periphery of the hole 2b,
Two locking pieces 2c having the same height as the skirt 2a
Is formed, and the locking claw 2d is formed inside the lower end of the locking piece 2c.
Is formed, the locking claw 2d connects the shoulder member 2 to the container body 1
Lip 11b formed on the neck when attached to
Has a structure for engaging with. When the shoulder member 2 is attached to the container body 1 by engaging with the notch 11c formed in the lip 11b of the neck 11 of the container body 1 by further forming a positioning protrusion 2e on the periphery of the hole 2b. Acts as a guide to.

A rib 2f is formed on the inner surface of the shoulder member 2 from the skirt 2a to the hole 2b at a position corresponding to the recess 12a of the container body 1 when the shoulder member 2 is attached to the container body 1. The lower end of the rib 2f is inclined so as to project into the space 4a at the end on the hole 2b side, and an inclined portion 2g is formed here. Therefore, the space 4a has a structure in which it gradually narrows from the container periphery toward the container center (see FIG. 4).

The bottom member 3 is a member made of a synthetic resin like the shoulder member 2, has the same shape and size as the cross section of the container body 1, has a skirt 3a provided upright on the periphery, and has an inner upper surface. Has two locking pieces 3 at the same height as the skirt 3a.
b is formed. The locking piece 3b has a locking claw 3c inside the upper end thereof, and the locking claw 3c engages with the lip 13b of the bottom portion 13 when the bottom member 3 is attached to the container body 1. Further, two positioning ribs 3d are formed inside the skirt 3a.

Further, like the shoulder member 2, the inner surface of the bottom member 3 is recessed in the container body 1 when it is attached to the container body 1.
A rib 3e is formed at a position corresponding to 13a. As described above, since the recess 13a has the inclined portion 13c, the space 4b formed between the bottom member 3 and the container body 1 becomes gradually narrower from the container periphery toward the container center (see FIG. 4).

The shoulder member 2 and the bottom member 3 are attached to the container body 1
When you apply force to the assembling, each locking piece 2
The locking claws 2d and 3c of c and 3b are the lip 11 of the container body 11.
The shoulder member 2 and the bottom member 3 are fixed to the container body 1 by getting over and engaging with each other. Spaces 4a and 4b formed between the container body 1 and the shoulder member 2 and the bottom member 3 open in a slit shape with respect to the outer peripheral surface of the container A. The side surfaces of the skirts 2a and 3a of the shoulder member 2 and the bottom member 3 are flush with the side surface of the container body 1 and are integrally designed.

Next, with reference to FIG. 5, an operation for removing the shoulder member and the bottom member, which are the different material members, from the different material member assembly container configured as described above will be described. Since the removal work of both members is performed in the same procedure, only the removal work of the shoulder member 2 is shown in the figure.

First, as shown in FIG. 1 (a), a plate-like member 5 such as a coin (hereinafter referred to as a coin) is prepared, and one end thereof is grasped with a finger and inserted into the space 4a. When the tip 5a of the coin 5 infiltrates to a predetermined position, the inclined portion 2 of the rib 2f
Although it abuts on g, the tip 5a of the coin 5 is further pushed until it abuts on the neck 11. At this time, the rib 2f is pushed upward, and as a result, the locking claw 2d can ride over the lip 11b and release the engagement between them.

Then, as shown in FIG. 3B, the rear end 5b of the coin 5 is pulled down to flip up the tip 5a, whereby the shoulder member 2 is further pulled up and removed. At this time, since the rear end 5b of the coin 5 to which force is applied is a force point, the end of the recess 12a of the container body 1 is a fulcrum, and the tip 5a of the coin 5 is a point of action, the lever principle is used. The shoulder member 2 can be removed.

On the other hand, also in the bottom member 3, by inserting the coin 5 into the space 4b, the inclined portion 13c of the recess 13a is formed.
Pushes down the tip of the coin 5, and this is the rib 3 of the bottom member 3.
Similarly, the bottom member 3 can be removed from the container body 1 by pressing e (see FIG. 4). The height that can be raised by inserting the shoulder member 2 coin 5 depends on the insertion distance and the inclined portion 2.
It is determined by the inclination angles of g and 13c, but these are adjusted to a predetermined value in consideration of the positions of the locking claws 2d and 3c and the lips 11b and 13b.

As described above, the container of this embodiment is
Simply insert the coin 5 into the space 4a, 4b and the shoulder member 2
Also, the bottom member 3 can be easily removed from the container body 1. Particularly, in this embodiment, the locking claws 2d and 3c and the lip are
The first operation for releasing the engagement between 11b and 13b and the second operation for pulling up the shoulder member 2 and the bottom member 3 by the principle of leverage are combined to remove the shoulder member 2 and the bottom member 3.
For this reason, even if the engaging claws 2d, 3c and the lips 11b, 13b have a large engaging force and the coin 5 must be inserted with a large force, the shoulder member 2 and the bottom member 3 are accidentally flipped up. Instead, the container can be easily disassembled by the user.

Next, a second embodiment of the present invention will be described with reference to FIG. The container B of this embodiment is an example in which an adhesive is used to engage the bottom member and the container body. FIG. 6 is a partial side sectional view of the same container.

The recess 12a formed on the upper surface rises from the peripheral edge of the container toward the center of the container, forming an inclined part 12c. On the other hand, the shoulder member 21 has a skirt 21a on the periphery thereof as in the first embodiment.
Is provided upright and a hole 21b through which the neck 11 can be inserted is formed in the center. Further, it is also the same that a plurality of locking pieces 21c having locking claws 21d are formed around the hole 21b.

The rib 21e formed at a position corresponding to the concave portion 12a of the container body 6 does not have an inclined portion at the lower end unlike the first embodiment. However, since the concave portion 12a has the inclined portion 12c as described above, the space 4a between the both is formed.
Has a structure in which it gradually narrows from the periphery of the container toward the center of the container.

On the other hand, the concave portion 13a formed in the bottom portion 13 of the container body 6 does not have an inclined portion, and on the contrary, the upper end of the rib 31d formed in the bottom member 31 extends from the skirt 31a toward the center of the bottom member 31. Gradually increasing to form an inclined portion 31e. Therefore, the space 4b formed in the container body 6 and the bottom member 31 also has a shape that gradually narrows from the container periphery toward the container center. The bottom member 31 does not have a locking piece, and its bottom surface is engaged with an adhesive 40 such as hot melt on its bottom surface.

Thus, also in this embodiment, the coin 5
The shoulder member 21 and the bottom member 31 can be removed from the container body 6 easily and with a small force by inserting into the spaces 4a and 4b. By using the adhesive, it is not necessary to form a lip or a locking claw, so that the mold can be made simpler and the assembling process can be simplified, so that a container having a lower manufacturing cost can be manufactured. Although only the bottom agent 31 is engaged with the container body 6 by using an adhesive in the present embodiment, the same structure can be applied to a shoulder member, and both the shoulder member and the bottom member are made of an adhesive container. It may be attached to the main body.
