Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dissimilar material assembly container in which a member formed of a material different from that of the container main body is attached to the shoulder and / or the bottom of the container, and particularly to the container main body. The present invention relates to a dissimilar material member-assembled container that facilitates separation of dissimilar material members.

[0002]

2. Description of the Related Art In various glass bottles, spray cans, PET bottles, etc., a different material is used for the shoulder portion or the bottom portion of the container body in order to improve the appearance, impact resistance, container stability and the like. It may be configured by fitting another formed member. Such a dissimilar material member needs to be fitted to the container body while the product is being used, and is often firmly attached so as not to accidentally come off.

[0003]

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 on the inner surface with the circumferential groove of the container body, and the force applied by the plate member releases the engagement between the two. Direction, that is, the container acts in a horizontal direction, and the force that acts in a direction for removing the bottom member, that is, in the vertical direction is small.

[0006] Therefore, an object of the present invention is to disassemble a dissimilar material member which is attached with a certain strength and which can be easily removed without a user's confusion when discarding a container. The purpose is to provide an attached container.

[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-like member, and the dissimilar material member is provided on the back side of the space. An integral rib is formed, and when the plate-shaped member is moved up and down about an arbitrary contact point with the container body as a fulcrum, the outer peripheral end of the dissimilar material member located on the opening side of the space is first And the end of the rib located in the inner part of the space as the second point of action to separate the dissimilar material member from the container body.

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. FIG. 1 is an exploded perspective view of the container, FIG. 2 is a partial side sectional view of the container, and FIG. 3 is a diagram for explaining an operation when removing a shoulder member and a bottom member.

As shown in FIGS. 1 and 2, a dissimilar material assembly container (hereinafter, simply referred to as a container) A according to the present invention is mounted on a shoulder 12 of a container body 1 for holding contents such as a cosmetic material. This is a container in which the shoulder member 2 is attached and the bottom member 3 is attached to the 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 is provided at the center of the shoulder portion 12 at the top of the container body 1.
11 are provided. 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. 2) can be inserted is formed. It is formed.

At the bottom 13 of the lower part of the container body 1, the container body 1
A recess 13a extending from the outer edge of the base 13 toward the center of the bottom 13 is formed, and a space 4b into which the plate member 5 can be inserted is formed similarly to the shoulder 12. Further, a step portion for assembling the bottom member 3 is formed, and the lip 13b is formed on the peripheral side surface of the step portion.
Are formed.

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. Further, on the lower surface of the shoulder member 2, two locking pieces (ribs) 2c having the same height as the skirt 2a are provided on the periphery of the hole 2b.
Is formed. This locking piece 2c has a locking claw 2 on the inside of the lower end.
The locking claw d has a structure to engage with the lip 11b formed on the neck portion when the shoulder member 2 is attached to the container body 1.

Further, a positioning protrusion 2e is further formed on the periphery of the hole 2b, and by engaging with the notch 11c formed in the lip 11b of the neck portion 11 of the container body 1, the shoulder member 2 is moved. It functions as a guide when it is attached to the main body 1.

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.

Since the end portions of the locking pieces 2c and 3b of the shoulder member 2 and the bottom member 3 serve as points of action of the principle of leverage as will be described later, the distance from the skirts 2a and 3a can be used. It is desirable that the length is not more than half the expected length of the plate member 5.

The shoulder member 2 and the bottom member 3 are connected 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. Even when the shoulder member 2 and the bottom member 3 are assembled, the skirts 2a, 3a and the locking pieces 2c, 3b do not enter the recesses 12a, 13a of the container body 1, and the spaces 4a, 4b are outside the container A. It opens in a slit shape. The side surfaces of the skirts 2a and 3a of the shoulder member 2 and the bottom member 1 are flush with the side surfaces of the container body 1 and are integrally designed.

Next, with reference to FIG. 3, 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, the first method for removing the shoulder member 2 is
As shown in FIG. 1A, a plate-like member 5 such as a coin (hereinafter,
A coin) into the space 4a between the shoulder member 2 and the container body 1 until the tip 5a of the coin touches the neck 11,
This is a method of holding the rear end 5b of the coin 5 and pushing it down.
Then, according to the so-called leverage principle, the end 12b of the recess 12a with which the middle portion of the coin 5 contacts is the fulcrum X, the rear end 5b that applies force to the coin 5 is the force point Y, and the tip 5a of the coin 5 is in contact with the locking piece 2c. The lower end acts as the point of action Z. Then, the pushing-down force applied to the force point Y is greatly amplified, and the locking piece 2c is lifted upward at the action point Z, and the locking claw 2
When d passes over the lip 11b, the engagement between the shoulder member 2 and the container body 1 can be easily released.

A second method for removing the shoulder member 2 is shown in FIG.
After inserting the coin 5 into the space 4a, as shown in (b),
This is a method of gripping and pulling up the rear end of the coin 5. In this case, the contact point of the tip of the coin 5 with the container body 1 is the fulcrum X, the gripping portion that applies a force to the coin 5 is the force point Y, and the skirt 2a in contact with the middle portion of the coin 5 is also based on the principle of leverage.
The lower end acts as the point of action Z. Then, the pulling force applied to the force point Y causes the skirt 2a at the action point Z.
Similarly, the engagement between the shoulder member 2 and the container body 1 can be easily released by lifting the lever upward and the locking claw 2d over the lip 11b.

As described above, the container of this embodiment is
After inserting the coin 5 into the space 4a, by pushing down or pulling up the rear end, the shoulder member 2 can be easily removed from the container body 1 with a small force using the principle of leverage. In particular, since the direction of the force applied to the coin 5 is not selected, the user can easily perform the work without any confusion even if the user does not have to learn how to use it, which is convenient.
The dissimilar material member becomes a removable container. The bottom member 3 can also be removed from the container body 1 by the same means.

Next, a second embodiment of the present invention will be described with reference to FIG. The container B of this embodiment is a container that is flipped up by a lever in two steps. FIG. 4 is a diagram for explaining the shape of the container of the second embodiment and its operation. In addition, the same structures as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. The same applies to the other embodiments described below.

As shown in FIG. 1 (a), the container body 6 of this embodiment has a stepped portion 12c formed in a recess 12a formed in a shoulder 12 thereof, and has a stepwise side cross section. ing. When the coin 5 is inserted into the space 4a between the shoulder member 2 and the container body 6 and the rear end 5b of the coin 5 is pushed down, the stepped portion 12c of the recess 12a with which the midway portion of the coin 5 abuts the first fulcrum X1. As a result, the tip 5a of the coin 5 lifts the locking piece 2c of the shoulder member 2.

Next, as shown in FIG. 2B, when the rear end 5b of the coin 5 is further pushed down, the middle part of the coin 5 comes into contact with the end 12b of the recess 12a, and the second end Fulcrum X
2, the tip 5a of the coin 5 can further lift the locking piece 2c.

When the shoulder member 2 is removed, a large force must first be applied because the locking claw 2d of the locking piece 2c needs to ride over the lip 11b of the neck 11, but in this embodiment, this first The distance from the fulcrum X1 of No. 1 to the lower end of the locking piece 2c serving as the point of action Z is from the first fulcrum X1 to the force point Y
Since it is much smaller than the distance to, the force amplification factor becomes large, and the engagement between the locking piece 2d and the lip 11b can be easily released with a small force. Then, when the rear end 5b of the coin 5 is further pushed down, the fulcrum moves to the second fulcrum X2, the movement stroke of the tip 5a of the coin 5 increases, and the shoulder member 2 can be easily lifted.

In FIG. 4, the rear end 5 of the coin 5 is
Although only the method of pulling down b to remove the shoulder member 2 has been described, the shoulder member 2 can be removed by pulling up the rear end 5b of the coin 5 as in the case of FIG. 3B of the first embodiment. Further, although only the shoulder member has been described here, it goes without saying that the same structure can be applied as a mechanism for removing the bottom member 3.

A third embodiment of the present invention will be described with reference to FIG. In the container C of this embodiment, the shoulder member and the container body are engaged with each other at the skirt of the shoulder member. FIG. 5 is a partial side sectional view of the container of the third embodiment.

As shown in the figure, the container body 7 of this embodiment
The shoulder 12 has a step 12d, and a lip 12e is formed around the shoulder 12. In addition, the shoulder member 21 of the present embodiment
Is a hole 21 for inserting the neck 11 of the container body 7 in the center.
b is formed, but unlike the shoulder members of the first and second embodiments, there is no locking piece, and the shoulder portion is formed on the inner surface of the skirt 21a.
Engaging claws 21c that engage with the lips 12e of 12 are formed.
Further, a rib 21d having the same height as the skirt 21a is formed on the inner lower surface of the shoulder member 21 at a position corresponding to the recess 12a of the shoulder portion 12. When the shoulder member 2 is engaged with the container body 7, a space 4a into which the coin 5 can be inserted is formed between the skirt 21a and the rib 21d and the shoulder portion 12.

The container C of this embodiment constructed as described above
Then, as in the first embodiment, the coin 5 is inserted into the space 4a, and then the rear end 5b is pushed down to form the concave portion.
The end 12b of 12a serves as a fulcrum, and the tip 5a thereof is lifted up, and the lower end of the rib 21d is pulled up, so that the shoulder member 2 can be removed from the container body 7. On the contrary, the rear end 5b of the coin 5
Can also be lifted up and the coin tip 5a can be used as a fulcrum to lift the lower end of the skirt 21a in the middle of the coin 5 and remove the shoulder member 2 from the container body 7.

A fourth embodiment of the present invention will be described with reference to FIG. In the container D of the present embodiment, the shoulder member and the container body are joined together with an adhesive. FIG. 6 is a partial side sectional view of the container of the fourth embodiment.

As shown in the figure, the container body 8 of this embodiment
Like the container body 7 of the third embodiment, the shoulder 12 has a step 12d. Further, the shoulder member 22 of the present embodiment has a skirt 22a standing upright on the periphery and a hole 22b through which the neck 11 is inserted at the center, similarly to the shoulder member of the third embodiment. Is not formed. Then, after an adhesive 40 such as hot melt is attached to the inner surface of the shoulder member 22, the skirt 22a is attached to the stepped portion 12d of the shoulder portion 12 to assemble them, and both are fixed by the adhesive 40. There is.

In this embodiment in which the shoulder member 22 and the container body 8 are engaged with each other by using an adhesive, it is not necessary to form a lip or a locking claw, so that the mold is simpler and the assembling process is simplified. Therefore, it is possible to manufacture a container having a lower manufacturing cost. In addition, although the third and fourth embodiments have been described with respect to only the shoulder member, it is needless to say that the bottom member can have the same configuration.

Further, a fifth embodiment of the present invention will be described with reference to FIG. The container E of this embodiment is formed by forming a notch on the shoulder member side in a space into which a coin can be inserted. FIG. 7 is a perspective view of the container of this embodiment.

As shown in the figure, like the container A of the first embodiment, the container E of this embodiment comprises a container body 9, a shoulder member 23 and a bottom member 33, and is formed on a locking piece (not shown). By engaging the locking claw and the lip formed on the neck 11,
These are assembled. However, no recess is formed in the shoulder 12 and bottom 13 of the container body 9, and conversely, notches are provided at the lower ends of the skirts 23a, 33a of the shoulder member 23 and the bottom member 33. Further, the above-mentioned locking piece is also lowered to form a space into which coins can be inserted, on the side of the shoulder member 23 and the bottom member 33. Then, similarly, by pulling up or pushing down the rear end of the coin, the shoulder member 23 and the bottom member 33 can be removed by the principle of leverage.

8 and 9 show a sixth embodiment of the present invention,
The perspective view of the container of 7th Example is shown. The containers F and G of these examples are made of different materials, namely, a shoulder member 24 and a bottom member.
Only 34 is attached. Each of these containers F and G has a shoulder portion 12 to which a shoulder member 24 or a bottom member 34 is attached.
Or, recesses 12a and 13a are provided in the bottom portion 13 to form a space into which a plate-shaped member can be inserted to form a structure similar to that of the first embodiment.

In each of the above-mentioned first to seventh embodiments, the container body is made of glass and the shoulder member and the bottom member are made of synthetic resin. However, in addition, a metal such as a spray can and a resin are mixed. Of course, the present invention can be applied to a container using different synthetic resins (for example, polyethylene and polypropylene) such as a plastic container or a PET bottle. In addition, although the plate-shaped member is described as a coin in the above-described embodiment, a clip, a flat-blade screwdriver, or the like can be used instead, or a dedicated detaching member can be prepared.

[0035]

As described above, the dissimilar material assembly container according to the present invention is provided with a lever member by inserting a plate member such as a coin into the slit provided in the dissimilar material member and pulling up or pushing down the rear end. Different materials can be easily separated by using the principle. Therefore, even if the dissimilar material member is firmly attached so that it is not accidentally detached while the product is being used, it can be easily separated by a general consumer when discarded.
