Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap device for a container provided with a cap main body of the container provided with a spout and a lid body for opening and closing the top wall side of the cap main body.

[0002]

2. Description of the Related Art A conventional container cap device is shown in FIG.
As shown in FIG. 41, a cap body 51 detachably attached to the mouth of the container, and a lid body 53 that covers the top wall 52 side of the cap body 51 in an openable and closable manner are provided. A mounting piece 57 is provided via a three-point hinge mechanism 56 having a hinge piece 54 and a connecting piece 55, the mounting piece 57 is mounted on the cap body 51, and the lid 53 is rotated about the hinge piece 54 as a fulcrum. As a result, the lid 53 covers the top wall 52 side of the cap body 51 so as to be openable and closable, and the action of the three-point hinge mechanism 56 causes the lid 53 to be covered.
Is held in a closed state in which the top wall 52 side of the cap main body 51 is capped and in an open state in which the top wall 52 side of the cap main body 51 is opened (for example, Japanese Utility Model No. 6-3
No. 804).

Further, in another conventional container cap device, as shown in FIGS. 42 and 43, a cap body 51 detachably attached to the mouth of the container and a top wall 52 side of the cap body 51 are provided. A lid 53 that can be opened and closed freely, and a mounting piece 62 is provided on the lid 53 via a hinge portion 61. The mounting piece 62 is attached to the cap body 51, and the lid body 53 supports the hinge portion 61 as a fulcrum. The lid body 53 covers the top wall 52 side of the cap body 51 so that the lid body 53 can be freely opened and closed by rotating the lid body 53, and a protrusion piece 63 is provided near the hinge portion 61 of the lid body 53. By contacting with the cap main body 51, there is a structure in which the lid 53 serves as a resistance when the lid 53 is opened and closed with the hinge portion 61 as a fulcrum, and the lid 53 is held in a closed state and an open state ( For example, real fair 4- 4129 JP).

Further, in another conventional container cap device, as shown in FIG. 44, a cap body 51 detachably attached to the mouth of the container and a top wall 52 side of the cap body 51 can be opened and closed. The ring body 6 via a connecting piece 65 having a hinge portion on the lid body 53.
6 is provided, the ring body 65 is externally fitted and fixed to the ceiling wall 52 of the cap body 51, and the lid body 53 is rotated around the hinge portion of the connecting piece 65 as a fulcrum so that the lid body 53 is covered with the ceiling wall of the cap body 51. There is one in which the 52 side is crowned so that it can be opened and closed (for example, Japanese Utility Model Publication No. 2-4055).

[0005]

However, in the case of the conventional example using the three-point hinge mechanism, a large cutout portion 58 corresponding to the connecting piece 55 is required in the lid body 53 from the outer end portion to the central portion. As a result, the appearance of the cap body 51 may be poor, and dust and water may enter the top wall 52 side of the cap body 51 from here. Further, a protrusion is formed on the back surface of the lid 53 by the three-point hinge mechanism 56, and the protrusion interferes with the use, and the protrusion may damage the shrink film for packaging the container. Furthermore, since the open position of the lid 53 slightly changes depending on the thickness of the three-point hinge mechanism 56 and the like, it is difficult to set the position of the open state of the lid 53.
There is a problem that the open position of the lid 53 cannot be set accurately.

Further, in the case of the conventional example in which the attachment piece and the protrusion piece are provided, the attachment piece 62 is attached to the top wall 52 of the cap body 51, and the hinge portion 61 is attached to the top wall 5 of the cap body 51.
2 is located above the cap body 5, the lid 53 is
1, the lid 53 is opened at a position close to the spout 64 of the cap main body 51, and the opening angle is small. Therefore, when pouring out the contents from the spout 64, the lid 53 is opened. There is also a possibility that the contents 53 may get in the way and the contents may adhere to the lid 53.

Further, in the case of the conventional example in which the ring body 66 is provided, the lid body 53 covers the cap body 51 with the ring body 66.
It can be easily and firmly attached to, but only by opening and closing the lid 53 with the hinge 61 as a fulcrum,
The lid 53 cannot be held in the closed state and the open state, which is very inconvenient when pouring out the contents.
In view of the above problems, the present invention has a good appearance because there is little protrusion such as a hinge portion, dust and water do not enter the top wall side of the cap body, and the lid body is opened wide relative to the cap body. In addition, the lid can be held in the closed state and the open state, and the open position of the lid can be set accurately.

[0008]

The first technical means of the present invention for solving this technical problem is a cap body 1 having a top wall 8 and an outer peripheral wall 5, and a top wall of the cap body 1. And a ring body 23 is provided on the lid body 13 via a connecting piece 25 having a hinge portion 22, and the lid body 13 is rotated by using the hinge portion 22 as a fulcrum. In a cap device for a container in which a ring body 23 is externally fitted and fixed to the outer periphery of the top wall 8 of the cap body 1 so that the body 13 can be opened and closed, the hinge portion 22 of the connecting piece 25 has the upper end portion of the outer peripheral wall 5 of the cap body 1. The ring body 23 is fitted and fixed to the outer peripheral portion of the top wall 8 of the cap body 1 so that the protruding piece 24 abutting the cap body 1 in order to hold the lid body 13 in the closed state and the open state. , Near the hinge portion 22 of the lid body 13, In that is provided so as to protrude downward than 22.

A second technical means is that a fitting recess 18 is provided on the upper end of the outer peripheral portion of the cap body 1, and a mounting recess 19 is provided on the outer periphery of the top wall 8 of the cap body 1.
The ring body 23 of No. 3 is fitted and fixed to the mounting recess 19 of the cap body 1, and the protruding piece 24 of the lid 13 is fitted to the fitting recess 18. The third technical means is
An annular recess 28 is provided below the mounting recess 19 of the cap body 1, and the lower end of the outer peripheral portion of the lid 13 is fitted onto the annular recess 28 when the lid 13 is closed.

[0010]

When the lid 13 is opened / closed and rotated, the tip end side of the protruding piece 24 comes into contact with the upper end of the outer peripheral wall 5 of the cap body 1 to be in a tensioned state, and the ring body 23 or the connecting piece 25 is elastically deformed. The extension piece 24 becomes a resistance when the lid 13 is opened and closed and rotated. Then, when the lid 13 is opened, the tip side of the protruding piece 24 comes into contact with the upper part of the inner wall surface of the fitting recess 18, and the lid 13 is opened by the urging action of the protruding piece 24. Retained. At this time, the lid body 13 can be widely opened with respect to the cap body 1, and the lid body 13 becomes an obstacle when pouring out the contents,
There is also no risk of the contents sticking to the lid 13. Further, it is easy to set the position of the lid 13 in the open state, and the open position of the lid 13 can be set accurately.

When the lid body 13 is closed, the projecting piece 24 holds the lid body 13 in the closed state.
