Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap used for a liquid dispensing container or the like.

"Problems to be solved by conventional technology and ideas" As a cap used for liquid dispensing containers, etc.
It is very commonly known that a container body with a mouth and neck part standing up from a body part has a top wall extending from the upper edge of the peripheral wall which is removably screwed onto the outer periphery of the mouth and neck part.
These caps are troublesome to handle because they have to be rotated and removed from the mouth and neck when dispensing the liquid content, and are similarly attached to the mouth and neck after use.

In addition, as a device that can alleviate such troubles to some extent, a bottle spout fitting with a lid that improves draining, for example, has been proposed (Japanese Utility Model Publication No. 15496/1983). This fitting was originally proposed to improve draining, but it has a structure in which a lid part with an engaging arm that engages with the bottle mouth is connected to a short cylinder part through a thin connecting part. When opening the lid, all you have to do is remove the engaging arm and rotate the lid, and after use, you only have to rotate the lid and engage the engaging arm with the outer periphery of the bottle mouth. This will save you some trouble.

However, with this attachment, there are still some aspects that are unsatisfactory when opening and closing the lid, such as the fact that it is extremely difficult to open and close with one touch with one hand. However, when the container is turned upside down, there is a risk that the lid may rotate and block the spout.

This invention solves the above-mentioned drawbacks of the conventional cap.The lid can be opened with one touch when dispensing the contents, and the lid can be closed with one touch after use.
Moreover, it is an object of the present invention to provide a cap that has a simple structure and is easy to manufacture, and also provides an excellent cap that does not cause the problem of the lid blocking the spout even when the container body attached to the lid is turned upside down. This is the purpose.

"Means for Solving the Problems" The front and rear walls 3a, 3b and the top wall 4 are hollow and open at the bottom, and the cross section of the walls 3a, 3b and the top wall 4 are horseshoe-shaped. The second rear wall 8 and the second top wall 9 are covered with the cap main body 1 and the outer surface of the rear wall 3b and the top wall 4 of the cap main body, and the lower end of the second rear wall 8 is covered with the outer surface of the cap main body 1. It consists of an elastic cover plate 7 connected to the lower end of the rear wall of the main body via a bending part 10, and a finger hook 12 is attached to the lower end of the front part 11 of the second top wall of the elastic cover plate, and the bending part The hole 5 for dispensing stored contents in the cap body is located outside the circumferential line with a radius from 1 to the front lower end of the second top wall, and elastic deformation of the lid plate 7 causes , the lid plate can be attached and detached from the cap body.

"Function" When the finger hook piece 12 is pushed up downward, the elastic cover plate 7 is elastically deformed so as to widen the diameter of its top wall portion 9, and rotates rearward around the bending portion 10. At this time, the base end of the finger hook 12 slides on the top surface of the cap body 1 from the front toward the top. When the base end of the finger hook 12 passes over a predetermined top wall 9, the elastic cover plate 7 automatically rotates rearward due to the elastic restoring force of the finger hook 12 even if there is no rearward pressing force. do. Therefore, for example, while holding the container body, use the finger grip piece 12 with your thumb.
If the elastic restoring force causes the cover plate 7 to rotate rearward, the cover can be opened with a single touch, and if the second rear wall 8 of the cover plate 7 is pressed, the cover can be closed with a single touch. becomes.

Furthermore, in order to pour out the contents after opening the lid, when the cap 1 is turned upside down as the container with the cap attached is turned upside down, the lid plate 7 rotates in a direction to cover the cap body. Since the hole 5 for dispensing stored items provided approximately in the center of the top wall 4 is located outward from the rotation locus centered on the bent portion 10 at the lower front end of the top wall portion 9 of the cover plate, in the natural state, As shown in FIG. 2, the rotation of the top wall portion 9 of the lid plate is stopped before the stored material pouring hole 5, and as a result, the stored material pouring hole 5 is maintained in a good open state.

"Embodiments" Hereinafter, embodiments of the present invention will be described based on the drawings. 1 and 2 show an embodiment of the cap of the present invention, in which 1 indicates the cap body and 7 indicates the elastic cover plate, respectively. The cap of this invention consists of a cap body 1
A thread is formed on the inner circumferential surface of the container body 13, and the thread is screwed into the thread on the outer circumference of the mouth and neck portion 14 of the container body 13. Further, the cap body 1 and the elastic lid plate 7 are integrally molded from synthetic resin.

The cap body 1 is hollow and has a semicylindrical shape with an opening on the lower surface, left and right side walls 2a, 2b are approximately vertical, front and rear side walls 3a, 3b and the top wall 4 are formed in a horseshoe shape in cross section, and the top wall 4 has a hole in the approximate center. A hole 5 for pouring out stored items is bored. Also, the rear wall 3b of the cap body 1
and a connected concave groove 16 is formed in the top wall 4,
The cover plate 7 is configured to be fitted into this concave groove so as to cover each other.

The elastic cover plate 7 covers the outer surfaces of the rear wall 3b and top wall 4 of the cap body with a second rear wall 8 and a second top wall 9, and extends the lower end of the second rear wall 8 to the rear of the cap body. It is connected to the lower end of the wall via a bent part 10. Further, a protruding plug body is provided from the center of the back surface of the second top wall portion 9 to be removably fitted into the contents pouring hole 5 of the cap body.

Furthermore, a finger hook piece 12 is attached to the lower end of the front part 11 of the second top wall part 9 of the elastic lid plate, so that the second
The hole 5 for dispensing stored contents in the cap body is located outside the circumference line with respect to the circumference line whose radius is up to the front lower end of the top wall, and elastic deformation of the lid plate 7 causes the cap body to The cover plate can be attached and detached from the

When dispensing the contents stored in the container body, etc., the cap configured as described above is lifted up from the state shown in FIG. is elastically deformed at its top wall portion 9 and rotates about the bending portion 10 as a fulcrum as shown by the imaginary line in the figure, and is removed from the top of the cap body 1.

As a result, the hole 5 for pouring out the stored contents opened in the top wall 4 of the cap main body is opened, and it becomes possible to pour out the contents stored in the container etc. to the outside.

After dispensing the contents, contrary to the above, the cover plate 7, which is in the state shown by the imaginary line in FIG. Just move it.

As a result, the top wall portion of the lid plate is elastically deformed, climbs over the top wall of the cap body, and is mounted on the cap body, thereby closing the hole 5 for dispensing the stored contents. (See the state shown by the solid line in FIG. 1).

Note that when the cap body is inverted in the above-mentioned state, the top wall of the lid plate cannot rotate in the direction in which the top wall of the cap body is removed for the same reason as explained in FIG. It goes without saying (see the imaginary line in Figure 2).

In the embodiments shown in FIGS. 1 and 2, the cover plate 7 is fitted in the concave groove 16 formed in the cap body 1, but as shown in FIG. The lid plate may be attached to a cap body having a flat rear wall and a flat top wall.

"Effects of the Invention" As explained above, according to the present invention, an elastic lid plate for opening and closing the contents pouring hole of the main body is rotatably connected to a part of the cap main body. The effect is that it is possible to form a discharge path for the contents stored in the container body, etc. with a single touch by a simple rotation operation without removing the cap from the container body, etc., and the commercial value of the container, etc. to which the cap is attached can be further increased. is obtained. Further, the structure is simple, and the cap body and the elastic lid plate can be integrally molded from synthetic resin, which has the advantage of reducing manufacturing costs.

Furthermore, when the lid is opened, there is no risk that the open lid plate will block the pouring hole, allowing for good pouring of the contents.
