Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation waste cap, and more particularly, to a separation waste cap attached to the mouth of a container. The present invention relates to a separation waste cap which can be removed from a part.

[0002]

2. Description of the Related Art In general, a container for sauce, soy sauce, oil or the like used at home is equipped with a cap for dispensing which serves both as a dispensing cylinder and a lid.

[0003] Such a pouring cap is made of a synthetic resin and is made of a material different from that of a glass container. It became mandatory.

In recent years, a container (pet bottle) made of polyethylene terephthalate has been used as a sauce or soy sauce container as described above, and such a PET bottle also has a cap for pouring as described above. It is installed.

In this case, the pouring cap and the container are common in that they are made of synthetic resin, but the pouring cap is made of polyethylene or polypropylene, whereas the container is made of polyethylene terephthalate. Since it is made of a synthetic resin of a different material, it is the same as a glass container in that it needs to be separated and collected.

[0006] Due to the above-mentioned requirement for separation and collection, it is necessary to separate the cap from the container after the contents in the container are consumed. This type of cap is attached to the mouth of the container by stoppering. Therefore, it is tightly fitted to the container,
In addition, the fitting portion is in a state of being pressed against the mouth of the container. Therefore, it is not easy to manually remove such a cap from the mouth of the container.

[0007] Therefore, for the purpose of separating and recovering, there have been invented various sorting and disposal caps which can be detached from the mouth of the container.

[0008]

However, in a conventional separation and disposal cap for this type of separation and disposal, a perforation or the like is formed in the cap body, and the cap body is formed at the perforation from the mouth of the container. Many have a structure that can be separated and removed. In such a structure, there is a possibility that the cap itself may be removed first before the spout is opened, thereby causing erroneous use.

For example, as disclosed in Japanese Patent Laid-Open No. 10-291555, a perforation is formed on the outer peripheral surface of the cap body, and a ring piece is cut through the perforation so that the cap body can be detached from the mouth of the container. And the like.

However, in such a structure, if the ring piece is broken along the perforation without following the perforation, the remaining piece of the ring piece remains in the mouth of the container while being integrated with the cap body. Therefore, the cap body cannot be removed from the mouth of the container.

A perforation is also formed in a separation waste cap other than the separation waste cap described in JP-A-10-291555,
A number of structures that divide along the portion have been developed, but the above problems cannot be solved.

On the other hand, a separation waste cap having a structure in which it is detached from the mouth of the container by means other than perforations has also been developed. However, there is a problem that the shape becomes complicated, and there is also a case where the capping line of the filling process has to be changed.

In another structure, there is a separation waste cap which requires a great deal of force to separate it.

The present invention has been made in order to solve the above-mentioned various problems in the related art, and can be mounted on the mouth of a container in a single stoppering step as in the case of the conventional cap. In addition, it is an object of the present invention to provide a sorting and disposal cap that can be easily removed from the mouth of a container without using a tool without requiring a great deal of force for detaching the attached cap after consumption of the contents. And

Another object of the present invention is to provide a sorting waste cap which does not require perforation and does not complicate the shape.

[0016]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the means for solving the problem is integrally formed so as to be externally fitted to a mouth of a container. A separation cylinder having an inner cylinder 5 and an outer cylinder 4, a rising wall extending above the inner cylinder 5, and a pouring cylinder 8 connected to the upper part of the rising wall. The tube 8 can be separated from the rising wall, the rising wall and the inner tube 5 can be separated from the outer tube 4, and the inner tube 5 can be pulled out of the mouth of the container after the separation. It is to be constituted.

When the separation waste cap having the above structure is to be removed from the mouth of the container, first, the pouring cylinder 8 is divided at the starting point of the division with respect to the rising wall, and the pouring cylinder 8 is further lifted. By dividing and further raising the pouring cylinder 8 in the divided state, the pulling force acts on the continuous portion of the inner cylinder 5 and the outer cylinder 4, and the rising wall and the inner cylinder 5 move with respect to the outer cylinder 4. Will be divided.

When the discharging tube 8 is further pulled up, the inner tube 5 is pulled out of the mouth of the container.

In this case, the spouting tube 8, the rising wall and the inner tube 5 are connected to each other after the division, and the inner tube 5 is formed so as to be able to be pulled out while the inner tube 5 and the outer tube 4 are connected. When the dispensing cylinder 8 is pulled up, the dispensing cylinder 8, the rising wall, and the entire inner cylinder 5 form a substantially rectangular shape, and the inner cylinder 5 is smoothly pulled out to the outside of the mouth of the container. It will be.

In addition, since the moment corresponding to the size of the pouring cylinder 8 acts on the inner cylinder 5, the inner cylinder 5 mounted inside the mouth 20 of the container 19 can be suitably moved with a relatively small force. It can be taken out of the mouth 20.

In the case where a rib is formed in a vertical direction from the dispensing cylinder toward the inner cylinder at a part where the dispensing cylinder and the rising wall are not divided, a lifting force of the dispensing cylinder is formed via the rib. Is suitably transmitted to the thin portion of the continuous portion between the outer cylinder and the inner cylinder, and the thin portion is suitably broken.

Further, when the groove is formed on both sides of the rib, the lifting force of the pouring cylinder is more likely to be concentrated at the portion where the rib and the thin portion are connected, so that the thin portion is more reliably separated. Will be done.

As shown in FIG. 11, the sorting waste cap 1 having such a configuration is used by being attached to the mouth 20 of a container 19.

More specifically, a groove 21 between the outer cylinder 4 and the inner cylinder 5 of the cap body 2 is fitted to the mouth 20 of the container 19 outside, and a bulge formed on the inner surface side of the outer cylinder 4. 22 is the mouth 20 of the container 19
Will be locked to the outer surface side of.

Thus, the separation waste cap 1 is
It will be attached so that it does not come off from the mouth 20 of the 19 carelessly.

In this case, the outer cylinder 4 is formed with cutouts 16, 16 serving as division starting points, and the cutouts 16, 16 are located above the bulging portion 22 formed on the inner surface side of the outer cylinder 4. When the sorting waste cap 1 is stopper-fitted, it does not break and break due to radial expansion from the skirt of the outer cylinder 4.

When the separation waste cap 1 is to be opened, the screw 18 of the cap body 2
By rotating the cover 4 screwed with the 13, the screwed state is released and the lid is opened as shown in FIG.
In this state, by pulling up the pull ring 9 as shown in FIG. 13, the sealing wall 10 is broken and opened.

After the contents have been consumed after opening, it is necessary to remove and discard the separation waste cap 1 from the mouth 20 of the container 19.

When performing such disposal, first, as shown in FIG. 14, one side edge of the pouring cylinder 8 is separated from the outer rising wall 6 and the inner rising wall 7.

This division is performed starting from the thin portion 11 shown in FIG.
