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, but it is a fact that it is discarded after use.

[0004]

However, in recent years, the treatment of industrial waste has become a kind of social problem.
Separation and collection by material are required, and in the near future separation and collection will be required by law (the Containers and Packaging Recycling Law).

[0005] For this reason, it is necessary to separate the cap from the container after the consumption of the contents, but since this kind of cap is attached to the mouth of the container by tapping, it fits tightly into the container. And the fitting portion is pressed against the mouth of the container. Therefore, it is not easy to manually remove such a cap from the mouth of the container.

Therefore, for the purpose of separation and recovery, various separation and disposal caps that can be detached from the mouth of the container have been invented.

However, this kind of conventional separation and disposal cap for separation and disposal has a structure in which a perforation or the like is formed in the cap body, and the cap body is separated from the opening of the container at the perforation and removed. There are many things. With such a structure, there is a possibility that the cap itself may be removed first before the spout is opened, thereby causing an erroneous use.

For example, as disclosed in Japanese Patent Application 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.

[0010] Even with a separation waste cap other than the separation waste cap of JP-A-10-291555, perforations are formed,
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 of being detached from the mouth of the container by means other than perforations has also been developed. However, there is a portion which protrudes outward so as to easily pick a portion serving as a starting point of a broken portion. 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.

[0012] 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 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 separation waste cap which does not require perforation and does not complicate the shape.

[0015]

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. In a separation waste cap having an inner cylinder 6 and an outer cylinder 5 and an ejection cylinder 7 connected to the upper part of the inner cylinder 6 and the outer cylinder 5, the ejection cylinder 7 includes the inner cylinder 6 and the outer cylinder 5. And the inner cylinder 6 is separable from the outer cylinder 5, and after the division, the pouring cylinder 7 and the inner cylinder 6 are connected,
The inner cylinder 6 is configured to be able to be pulled out to the outside of the mouth of the container in a state where the inner cylinder 6 and the outer cylinder 5 are connected to each other.

When the separation waste cap having the above structure is to be removed from the mouth of the container, first, the spouting tube 7 is separated from the inner tube 6 and the outer tube 5 at the starting point of the separation. By pulling up, the pulling cylinder 7 is further pulled up, and the pulling force acts on the continuous portion of the inner cylinder 6 and the outer cylinder 5 so that the inner cylinder 6 Will be divided.

When the pouring cylinder 7 is further pulled up, the inner cylinder 6 is pulled out of the mouth of the container.

In this case, the spouting cylinder 7 and the inner cylinder 6 are connected to each other after the cutting, and the inner cylinder 6 is formed so as to be able to be pulled out while the inner cylinder 6 and the outer cylinder 5 are connected. Therefore, when the pouring cylinder 7 is pulled up, the pouring cylinder 7 and the inner cylinder 6 have a substantially rectangular shape, and the inner cylinder 6 is smoothly pulled out to the outside of the mouth of the container.

In addition, since the moment corresponding to the size of the pouring cylinder 7 acts on the inner cylinder 6, the inner cylinder 6 mounted inside the mouth 17 of the container 18 can be suitably moved with a relatively small force. It can be taken out of the mouth 17.

Further, when a division starting point 21 for dividing the outer cylinder 5 in the vertical direction is formed in a part of the outer cylinder 5, the inner cylinder 6 is pulled out of the mouth of the container and then divided. The outer cylinder 5 is cut off via the starting point 21, and the entire separation waste cap including the pouring cylinder 7, the inner cylinder 6, and the outer cylinder 5 can be removed from the mouth of the container.

In particular, when the dividing starting point 21 is formed at a position facing the connecting portion 19 between the pouring cylinder 7 and the inner cylinder 6,
The pulling-out force of the inner cylinder 6 pulled out of the mouth of the container suitably acts on the division starting point portion 21, and furthermore, the entire dimensions of the pouring cylinder 7 and the inner cylinder 6 which are pulled up in a substantially rectangular shape. Is applied to the division starting point portion 21, so that the outer cylinder 5 can be easily divided by a small force.

In this case, the outer tube 5 may be torn in the vertical direction as it is from the division starting point 21, or by pulling up halfway and pulling up the pouring cylinder 7 and the inner cylinder 6 in the direction opposite to the division starting point 21. The entire dispensing cylinder 7, the inner cylinder 6, and the outer cylinder 5 can be removed from the mouth of the container.

As described above, according to the present invention, the dispensing cylinder can be divided into the inner cylinder and the outer cylinder, and the inner cylinder can be divided from the outer cylinder. The outlet cylinder and the inner cylinder are connected to each other, and the inner cylinder is configured to be able to be pulled out to the outside of the mouth of the container in a state where the inner cylinder and the outer cylinder are connected to each other. Connecting part of the cylinder and the inner cylinder,
The spout cylinder and the inner cylinder are pulled up in a substantially U-shape through the continuous portion of the inner cylinder and the outer cylinder, and the moment corresponding to the size of the spout cylinder acts on the inner cylinder. With a relatively small force, the inner cylinder attached to the inside of the mouth of the container can be easily and smoothly taken out of the mouth.

Further, in the case where a division starting point for dividing the outer cylinder in the vertical direction is formed in a part of the outer cylinder, the inner cylinder is pulled out of the mouth of the container and then passed through the division starting point. As a result, there is an effect that the entire separation waste cap including the spouting cylinder, the inner cylinder, and the outer cylinder can be removed from the mouth of the container.

In particular, when the dividing starting point is formed at a position opposed to the connecting portion between the spouting cylinder and the inner cylinder, the pulling force of the inner cylinder pulled out of the mouth of the container increases the dividing starting point. The outer cylinder is easily divided by a small force because a moment corresponding to the entire dimensions of the spouting cylinder and the inner cylinder which acts on the portion and is pulled up in a substantially V-shape acts on the division starting point. You can do it.

In this case, in addition to tearing the outer cylinder in the vertical direction as it is from the division starting point, the dispensing cylinder, inner cylinder, This has the effect that the entire outer cylinder can be removed from the mouth of the container.

Further, since the separation is performed in two stages as described above, the force for removing the separation waste cap from the container is light, and it is easy for a housewife or the like who mainly handles kitchen utensils to handle, and the work for separation and collection is easy. The effect is as follows.

Further, there is a great advantage that there is no need to use any tools or instruments such as a bottle opener for removing the cap and pliers.

Further, it is not necessary to form a portion for projecting outward such as a ring for removal, so that the shape is simplified, and it is not necessary to change the filling line when filling the contents into the container. There are advantages.

As described above, according to the present invention, since the separation and disposal cap can be easily detached from the mouth of the container, it is possible to provide a separation and disposal cap that complies with the regulation of container packaging recycling, which is required to separate and collect. There are benefits.
