Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap in which a base body and a lid body are connected to each other via a hinge, and the lid body is rotatably attached to the base body.

[0002]

[Prior art]

 As shown in FIGS. 9 and 10, a conventional cap of this type is made of synthetic resin, and has an inner cylinder 32 and an inner cylinder 32 formed by leaving a gap 31 into which a bottle mouth is inserted. A hinge 34 is extended to one side of the base body 1 and the lid body 2 having a central cylinder 33 formed in the cylinder 32, and the ends are connected by a bendable thin portion 35, and a base portion 36 is provided on the left and right of each hinge 34. , 37 are raised and connected at their upper and lower ends with elastically deformable strips 38, 38 having bendable and thin portions 36a, 37a, and these strips 38, 38 are elastically deformed. As a result, a measure is taken to increase the openness of the lid 2.

[0003]

[Problems to be solved by the device]

 However, the conventional cap has a problem that the elastic force of the strips 38, 38 decreases according to the opening / closing frequency of the lid 2, and the degree of opening gradually decreases. Further, since the strips 38, 38 greatly protrude outward in the side surfaces of the base body 1 and the lid body 2 in the closed state of the lid body 2, there is a problem that the appearance of the cap is impaired.

Therefore, the present invention has been made for the purpose of solving the problems of the conventional cap.

[0005]

[Means for Solving the Problems]

 Therefore, in the cap of the present invention, a part of the upper part of the side circumference 1a of the base body 1 and a part of the lower part of the side circumference 2a of the lid body 2 are continuously connected to the hinge 3 which is elastically deformable in the shape of a short strip and both sides of this hinge 3. It is assumed that they are connected via an elastically deformable hinge 4 having a shape composed of a part 4a of the truncated cone surface 4a.

Further, in the cap of the present invention, a part of the upper part of the side circumference 1a of the base body 1 and a part of the lower part of the side circumference 2a of the lid body 2 are abutted at the top parts of the conical surface parts 5a, 5a, respectively. It is assumed that they are connected via an elastically deformable hinge 5 having the following shape.

[0007]

[Action]

 The cap of the present invention, having the above-mentioned means, has the following operation. First, when the lid body 2 is changed from the closed state to the open state, the elastically deformable hinges 4 having the shape of the truncated cone surface portions 4a and 4a or the conical surface portions 5a and 5a are butted against each other at their tops. The elastically deformable hinge 5 having the shape is bent back to maintain the opened state.

In the closed state, the conical surface portions 4a, 4a or the conical surface portions 5a, 5a only slightly project from the upper periphery of the base 1 and the lower periphery of the lid 2. Is.

【Example】

 The structure of the cap of the present invention will be described below with reference to the drawings showing an embodiment. FIG. 1 is a perspective view of the cap of the present invention with the lid closed, and FIG. 2 is a perspective view of the cap of the present invention with the lid open. The cap of this idea is made of a synthetic resin integrally molded product, and a part of the upper portion of the side circumference 1a of the base body 1 and a part of the lower portion of the side circumference 2a of the lid 2 are connected via a hinge 3 and a hinge 4. I am supposed to.

As shown in FIG. 3, the base body 1 has an outer cylinder 11 and an inner cylinder 12, and a standing cylinder 14 having a diameter slightly larger than that of the inner cylinder 12 is provided on the upper surface 13. Further, a so-called pull-top type opening body 15 is provided on the upper surface 13 of the base 1. Then, the base body 1 is attached to the mouth portion of the bottle by fitting a mouth portion (not shown) of the bottle between the outer cylinder 11 and the inner cylinder 12. In addition, as shown in FIG. 4, a groove 16 is formed on the inner circumference of the upper end of the upright cylinder 14 so that a liquid having viscosity such as oil or detergent is poured out from the bottle. Is doing better.

The lid 2 is provided with a locking piece 21 at a part of the end of the side circumference 2 a, and a back wall 22 is provided with a peripheral wall 23 just fitted into the standing cylinder 14 of the base body 1. The hinge 3 has a short strip shape and is elastically deformable, and the hinge 4 is elastically deformable in a shape composed of parts 4a and 4a of a truncated cone surface continuously provided on both sides of the hinge 3. Further, instead of the hinges 3 and 4, as shown in FIG. 5, elastically deformable hinges 5 having a shape in which parts 5a and 5a of the conical surface are abutted at their tops may be used.

As shown in FIGS. 2 and 3, the cap of the present invention is integrally molded of synthetic resin with the lid 2 opened and the base 1 and the lid 2 being substantially horizontal. . With the cap of the present invention constructed as described above, the lid 2 is opened and closed as follows. First, in order to open the lid body 2, the locking piece 21 of the lid body 2 is pulled up with a fingertip, and the lid body 2 is closed from the state shown in FIG. 6 to the position shown in FIG. When 2 is opened, the lid 2 tries to return to the base 1 side by the restoring force of the hinges 3 and 4 at this position. However, when the lid body 2 is opened beyond the position shown in FIG. 7 to the position shown in FIG. 8, the hinge 4 warps back to maintain this opened state. Therefore, if the locking piece 21 of the lid body 2 is pulled up with a fingertip and the lid body 1 is opened to the position shown in FIG. 8 at a time, the lid body 1 will be opened greatly without returning to the closing direction. You can leave it in the ready state.

Needless to say, to close the lid body 2, the lid body 2 may be pinched with a fingertip and returned to the position shown in FIG. In this case, when the lid body 2 passes over the position shown in FIG. 7, the lid body 2 tries to return to the base body 1 side by the restoring force of the hinges 3 and 4, so that the lid body 2 naturally moves. The lid body 2 can be completely closed by approaching the closed state and finally pressing the upper portion of the lid body 2.

[0014]

[Effect of device]

 The cap of this invention has the following effects because it is configured as described above. First, when the lid body 2 is changed from the closed state to the open state, the hinge 4 or the hinge 5 tries to maintain the opened state by being bent back. Therefore, the opening degree of the lid body 2 depends on the opening / closing frequency of the lid body 2. As a result, it never became smaller.

Further, in the closed state, the part 4a, 4a of the truncated cone surface or the part 5a, 5a of the cone surface slightly protrudes from the upper circumference of the base body 1 and the lower circumference of the lid body 2. Therefore, the appearance of the cap is no longer impaired.
