DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin lid which is fitted to the mouth and neck of a hollow container and has a structure for closing the opening. A hinge lid in which a fitting cylinder portion closely fitted to the mouth and neck of the hollow container and a lid portion for closing the opening portion are openably and closably connected via a hinge so that the opening portion can be opened and closed. The present invention relates to a hinge lid having a structure such that a lid can be easily separated from a container body when used and discarded.

[0002]

2. Description of the Related Art As a lid for sealing the opening of various bottle-shaped liquid hollow containers made of glass, synthetic resin, etc., it has recently become possible to reseal it by injection molding of thermoplastic synthetic resin. Various types of opening / closing lids have come into widespread use, and among others, liquid seasonings such as soy sauce and mirin, which are used daily, or other hollow containers containing liquids that are frequently used. As a lid that seals the opening, a hinge-type lid that can be easily opened and closed and is convenient is often used.

A hinge lid used for various kinds of hollow containers containing a liquid as described above is provided with a fitting cylindrical portion closely fitted to the mouth and neck of the hollow container, and a hinge connected to the fitting cylindrical portion via a hinge. A lid portion that is openably and closably connected, and an inner lid that is connected to the inner cylinder wall of the fitting cylindrical portion and seals the opening is formed so as to be able to be shredded. Unless it is possible to pour out the contents, it has a structure. Therefore, the hollow container using the hinge lid body having such a structure can prevent the contents from being illegally opened and the contents poured out, or foreign substances mixed into the container, and
The lid, which can be opened and closed, has a good sealing property, and is widely used because of its convenience such that once used, it can be easily sealed again.

[0004] A sealed container using a hinge-type lid having such an openable and closable closed structure is in a tightly sealed state so that the contents in the container do not leak from the mouth and neck. Since the contents can be preserved for a long period of time by improving the sealing property, the fitting cylinder portion in which the lid is fitted to the mouth and neck of the container,
It has a structure fitted as tightly as possible to the mouth and neck of the hollow container, so even if you try to remove the lid of such a container from the container body with bare hands, It is almost impossible to remove easily.

[0005] Because of the various conveniences described above, various types of liquid beverages and other liquid beverages are being consumed in large quantities in addition to liquid seasonings with the recent changes in lifestyle. As a container for accommodating these items, a hollow container using the hinge lid having the above-described structure has been mass-produced to satisfy the demand. As these products are consumed in large quantities and used containers are disposed of as garbage, treating these used containers as garbage causes a serious social problem. As it became more common, these containers were separated from general household waste, collected, and recycled, which was required by the enforcement of the Container Recycling Law.

[0006] However, most of the conventional containers with a hinge lid as described above are hermetically-sealed containers fitted to the container body and the mouth and neck for various economic and technical reasons. The lid was made of a different material. Therefore, in order to collect and reuse these used and discarded containers, it is necessary to separate the container body and the sealed lid and then recycle them as raw materials. Such a container, when discarded, the container body and the sealed lid are separated and then discarded, or
Since the hermetic lid must be separated from the container body after separating and collecting only the container, it is a necessary condition for reuse that the lid can be easily separated from the container body.
Therefore, the closed lid used for the container as described above is structured so that only the lid can be easily separated from the container main body with bare hands, and the cost required for recovery and regeneration can be reduced. However, it has become an indispensable condition for promoting the recycling of such containers.

[0007] When the hollow container using the hinge type lid as described above is used and discarded, some sort of separating means for separating the lid from the container body is provided on the lid. As provided, Japanese Utility Model Laid-Open No. 4-118348
As disclosed in Japanese Unexamined Patent Application Publication No. 5-34151, a breakable thin portion or a weakening line is formed at the lower end of a fitting cylindrical portion of a hinge lid fitted to the mouth and neck of a container. Is provided, and a gripping piece for cutting off the thin-walled portion is pinched with a fingertip and pulled, or the lower end of the fitting tube portion is cut off by gripping and pulling an open lid. A structure in which a lid is separated from a container body is known.

Another format is disclosed in Japanese Patent Application Laid-Open No. 9-1425.
No. 06 and Japanese Utility Model Publication No. 7-40500,
In order to enable the lid to be separated using the bottle opener, various shapes of engagement portions are provided with which the bottle opener engages with the fitting cylindrical portion of the hinge lid fitted to the mouth and neck of the container. Is provided, the stopper is engaged with the engaging portion of the stopper, the pressing portion is applied to the top plate of the lid, and the top plate portion is used as a fulcrum in the same manner as when the crown plug is removed. There is known a structure which can be separated by utilizing the principle of leverage.

However, as in the former type, a breakable thin portion or a weakening line is provided at the lower end of the fitting cylinder, and the lid is separated after the lower end of the fitting cylinder is cut off. The structure that does not require a special tool to separate the lid, so that the lid can be separated from the container body whenever it is no longer necessary and is discarded, Since a certain amount of force is required to break the thin-walled portion and the weakened line of the cylinder, it is impossible to easily separate it for children and weak people. Since the lid may be broken, it is not a perfect separation means.

[0010] In the latter type, a structure in which a separating means is used with a bottle opener as a separating means does not require a large force, so that even a child or a sick person can easily separate. However, it is necessary to always prepare a bottle opener for separation, and when separating the lid with the front opener, it is necessary to cut off the lid part of the hinge lid in advance. There was a drawback that the bottle opener could not be hooked, and this was somewhat troublesome. Further, in order to apply the bottle opener, it is necessary to form an uneven portion on the side surface of the lid for engaging the bottle opener. Therefore, a container equipped with such a lid has a design limitation. In order to make the appearance worse and reduce the value received by the consumer for the product, and to form an uneven part on the fitting cylinder part of the lid, it is necessary to use a molding die that has been used in the past. There is a drawback that another molding die must be prepared.

Therefore, as for the hollow container using the hinge type lid as described above, a method for reliably and easily separating the lid from the container body is as follows.
Although it is a method of separating using a bottle opener as a separating means, the hinge lid having the conventional structure has various disadvantages as described above, and various measures have been made to eliminate these disadvantages. I have. And Japanese Patent Laid-Open No. 2000-5
No. 3,156, JP-A-2000-103449, etc., a hinge lid is formed so that it can be separated using a bottle opener without cutting off the lid of the hinge lid fitted to the hollow container. A hinge lid having a simple structure has been proposed.

In the hinge lid of the invention described above, the stopper can be easily hooked on the hinge lid without forcibly removing the lid, and the lid can be pulled out from the container body and separated. The following structures formed in various structures are known. For example, what is shown in FIG. 5 is a rigid projection 22 of an outer cylinder 22 of a hinge lid for engaging a stopper 27.
a part 2 of the pouring cylinder 25 of the inner lid 24 serving as a fulcrum corresponding to a
By forming 5a in a thin shape, the rigid protrusion 22
a thin portion 25a at the pressing portion 27a of the bottle opener 27
When the is pressed, the thin portion is easily deformed inward and is bent and bitten into a state where it is bitten, and the flexible inner lid 24 and the rigid outer lid 26 are integrated with the portion 25a as a fulcrum, and It is formed so as to be separated from the mouth and neck 2a. 6 is provided with a protruding locking portion 35a for locking the bottle opener 37 on the side surface of the spout cylinder 35 of the hinge lid provided with the inner cover 34. Is pulled up with the tip end of the ejection tube 35 in contact with the pressing portion 37a engaged so as to be hooked on the locking portion as a fulcrum.
The hinge lid is formed so as to be separated from the container body.

The hinge lid having the above-described structure is
Even if the lid portion of the hinge lid body is not forcibly cut off as in the conventional case, the lid body can be reliably and easily separated from the container body by using the bottle opener, and the appearance thereof can be improved. Although it is not enough to reduce the value of the product, however, in order to mold the mouth and neck into a special structure like such a lid, the structure of the molding die is a little complicated. Since it is inevitable, it cannot be configured using a molding die that has been used conventionally, and it is difficult to keep the manufacturing cost of the lid low.

Therefore, even if the lid portion of the hinge lid is not cut off, the lid can be easily separated from the container body by using a bottle opener, and the appearance is poor so as to reduce the commercial value. A hinge lid that does not present a structure that can be separated more easily than conventional hinge lids, and that a molding die is formed using a conventionally used molding die. It is desired to have a hinge lid having a structure that can be formed.

[0015]
