Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hinged cap having a lid that is opened and closed by a hinge.

[Conventional technology]

Conventionally, this type of container has been described in Japanese Utility Model Application Publication No. 56-84951 shown in FIG.

The above-mentioned publication describes that the main body peripheral wall 23 and the upper lid 22 are connected by a hinge part 25, and that from the lower inner surface of the main body peripheral wall part 23 adjacent to the hinge part 23, there is an appropriate space between the main body peripheral wall surface and the main body peripheral wall surface. , 1st
The elastic plate part 20 is made to protrude upward, and the second elastic plate part 26 is vertically provided in the gap from the inner surface of the upper lid 22, so that these hinge parts 25 and the first and second elastic plate parts 2
0 and 26, which form an elastic reversing means for opening and closing the upper lid 22, is described.

[Problem that the invention attempts to solve]

The hinge cap described in the above-mentioned Japanese Utility Model Publication No. 56-84951 has a first elastic plate 2 formed in a protruding manner.
By imparting an elastic force to 0, the first elastic plate portion 20 and the second elastic plate portion 26 are elastically reversed. Therefore, as shown in FIG. 5, a space 27 must also be formed inside the first elastic plate section 20.
Therefore, the elastic reversing means has a complicated structure, making it difficult to mold the member. Also,
It is necessary to provide a wide bottom wall 28, which serves as a base for the first elastic plate part 20 and the cavities 27 and 29, and the internal space of the container opening becomes narrow, making it difficult to pour out the contents. Furthermore, since the first elastic plate portion 20 protrudes upward, the container ends up having an unsightly appearance.

This idea was created with these points in mind.
To form a hinge cap with a simple structure without any outwardly projecting members, and to make it easy to pour out the contents.

[Means for solving problems]

In order to solve the above technical problem, the present invention takes the following technical measures.

A cylindrical body 3 to be fitted onto the mouth cylindrical portion 2 of the container 1 is provided,
At least one side thereof is provided with an outer wall 6 that is spaced apart from the cylindrical body 3 to form a space 7 between them and has elasticity, and the outer wall 6 and the cylindrical body 3 are arranged so that at least the upper part thereof is open. Molded in one piece.

Furthermore, a lid 8 for opening and closing the upper surface of the cylinder 3 is connected to the upper part of the outer wall 6 by a hinge, and a projecting piece 11 is provided to project from the hinge connection portion of the lid 8.

The length of this protruding piece 11 is set to be slightly longer than the distance between the upper part of the cylinder body 3 and the outer wall 6, and the direction of this protruding piece 11 is set so that the distance between the cylinder body 3 and the outer wall 6 when the lid body 8 is closed is set. Orient it in the direction in which it will be inserted into the space 7 between.

[Effect]

The length of the protruding piece 11 is set to be slightly longer than the distance between the upper portions of the cylindrical body 3 and the outer wall 6. Therefore, if you try to open the lid 8 with the lid 8 closed and the protruding piece 11 inserted into the space 7 between the cylinder 3 and the outer wall 6, the protruding piece 11 will hit the wall of the cylinder 3. This prevents the lid 8 from opening. Therefore, the lid body 8 is kept closed. The outer wall 6 has elasticity and moves in the circumferential direction, and the hinge portion does not protrude outward in the closed state.

When opening the lid 8, even if the protruding piece 11 comes into contact with the wall surface of the cylindrical body 3, if the lid 8 is further opened while keeping this in contact, the protruding piece 11 will come into pressure contact with the wall surface of the cylindrical body 3. Then, the outer wall 6 separates from the cylindrical body 3, and the protruding piece 11 comes out of the space 7 between the cylindrical body 3 and the outer wall 6, and the lid 8 opens. Then, as the protruding piece 11 escapes from the space 7, the outer wall 6 returns to its original position, so that the tip of the protruding piece 11 comes into contact with the upper part of the cylindrical body 3 to hold the lid 8 in an open state.

As described above, since the length of the protruding piece 11 can be absorbed by the movement of the outer wall 6, the portion of the elastic reversing means does not become large in the circumferential direction. Therefore, the internal space of the container opening can be made wide, making it easier to pour out the contents.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3.

A cylindrical body 3 to be fitted onto the mouth part 2 of the container 1
This cylindrical body 3 is adapted to be screwed into the mouth tube part 2 by a thread carved on the inner surface, and a top plate 4 is provided at the upper end to close the upper end opening of the mouth tube part 2. A spout 5 is provided on the top plate 4 with a slight deviation.

A cylindrical outer wall 6 is provided to surround the cylindrical body 3, and the lower part of the cylindrical outer wall 6 is connected to the lower part of the cylindrical body 3.
They are separated from each other to form a space 7 between them.
The outer wall 6 and the cylindrical body 3 are integrally molded of synthetic resin so that at least the upper portion thereof is open, and the outer wall 6 has elasticity.

Furthermore, a lid 8 for opening and closing the upper surface of the cylinder 3 is connected to the upper part of the outer wall 6 by a thin hinge 9, and a lid 8 is fitted into the spout 5 on the lower surface of the lid 8 when the lid 8 is closed. A plug protrusion 10 is provided vertically.

Further, a projecting piece 11 is provided in a protruding manner at the connecting portion of the lid body 8 with the hinge 9, and the length of this projecting piece 11 is set to be slightly longer than the distance between the upper part of the cylinder body 3 and the outer wall 6. At the same time, the projecting piece 11 is oriented in the direction in which it is inserted into the space 7 between the cylinder body 3 and the closure 6 when the lid body 8 is closed.

The length of the projecting piece 11 is the same as that of the cylindrical body 3 and the outer wall 6.
Since the distance is set slightly longer than the distance between the upper part of the cylinder body 3 and the outer wall 6, even when the lid body 8 is closed and the protruding piece 11 attempts to move between the cylinder body 3 and the outer wall 6, the protruding piece 11 will not hit the wall surface of the cylinder body 3. Once the lid 8 is prevented from opening, the lid 8 is kept closed.

However, if the lid 8 is forcibly opened, the protruding piece 11 will push the wall surface of the cylinder 3, causing the outer wall 6 to separate from the cylinder 3, and the protruding piece 11 will close the space between the cylinder 3 and the outer wall 6. It escapes from the location 7 and the lid body 8 opens. And protrusion 11
Since the outer wall 6 returns to its original position as the outer wall 6 escapes from the space 7, the tip of the protruding piece 11 comes into contact with the upper part of the cylindrical body 3 and holds the lid 8 in an open state.

In this embodiment, the cylinder 3 is made cylindrical and the outer wall 6 is also made cylindrical. However, as shown in FIG.
It may have a shape corresponding to

[Effect of idea]

As described above, the present invention is provided with an elastic outer wall that is separated from the cylindrical body and forms a space between them, so it is possible to provide a hinge cap in which the hinge portion does not protrude outward. It has a simple structure and can be molded to look good.

Furthermore, since the internal space of the container opening can be made wide, it becomes easier to pour out the contents.
