Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a container cap.

[Conventional technology]

Conventionally, as shown in FIG.
A wavy stepped portion 33 is provided at the base of the container 2, and an annular projection 34 is provided on the outer periphery of the intermediate portion of the mouth and neck portion 32. An inner cylinder 35 is provided for locking, and when the inner cylinder 35 rotates, the tip edge of the inner cylinder 35 is pushed up to the highest part of the wavy stepped portion 33 and the annular protrusion 3
4 and is detached from the mouth and neck part 32 of the container 31 is known.

[Problem that the invention attempts to solve]

However, with such a structure, the container 31
When the cap is knocked over or dropped, if the cap hits the floor or the like and a load is applied, the engagement between the inner cylinder and the annular protrusion 34 may be disengaged, and the cap may come off the container 31.

This idea was created with these points in mind.
The technical challenge is to prevent the container from falling off even if it is knocked over.

[Means for solving problems]

In order to solve the above-mentioned technical problem, the present invention employs the following technical means.

That is, the inner stopper 4 having the spout 6 is fitted into the mouth 2 of the container 1 . Then, the cap body 8 is attached to the neck part 3 of the container 1 forming the mouth part 2 of the container 1. This cap body 8 holds down the inner stopper 4 and prevents it from coming off the mouth 2 of the container 1. Incidentally, the inner plug 4 and the cap main body 8 may be formed integrally rather than separately. Furthermore, a corrugated stepped portion 16 is formed on the inner surface of the cap body 8, and a rotary ring 14 is rotatably attached thereto. Then, the outer plug 17 is rotated, which has a wavy peripheral wall 18 on the outer peripheral edge corresponding to the wavy stepped portion 16 of the rotary ring 14 and a plug body 19 in the center that closes the spout 6 of the inner plug 4. It is provided so that it can be removably locked in the moving ring 14.

[Effect]

When the rotating ring 14 is rotated, the outer plug 17 is pushed up and removed via the wavy peripheral wall 18 by the wavy stepped portion 16, and the engagement between the plug body 19 and the spout 6 of the inner plug 4 is released, and the spout is removed. 6 opens.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

1 is a container, and this container 1 is provided with a neck part 3 forming a mouth part 2 at the upper part.

Then, the inner stopper 4 is fitted into the mouth 2 of the container 1,
The inner plug 4 has a spout 6 formed by a cylindrical nozzle 5 in the center, and an annular groove 7 is formed on the inner surface of the spout 6.

Further, a cylindrical cap body 8 is screwed onto the mouth and neck portion 3. The upper end surface of the cap body 8 is closed with a closing plate 9, and the closing plate 9 has a hole 10 with a diameter slightly larger than the nozzle 5 in the center. While the nozzle 5 of the inner stopper 4 is projected from the hole 10, the inner stopper 4 is pressed by the peripheral edge of the hole 10 to prevent the inner stopper 4 from coming off the mouth 2 of the container 1.

An annular rail 11 is provided on the periphery of the closure plate 9 above the cap body 8, and a rectangular rail 11 is provided on the closure plate 9 between the hole 10 and the annular rail 11 when viewed from above. 1 rectangular cylinder 1
2 is provided protrudingly. The first rectangular cylinder 12 has a corner portion on the inner surface side of the upper edge thereof which is chamfered to form a first inclined surface 13 .

A rotating ring 1 is rotatably attached to the annular rail 11 on the cap body 8.
4, the outer surface of this rotary ring 14 is provided with knurling eyes 15, and the inner surface thereof is provided with a wavy stepped portion 16.

Further, an outer plug 17 having a diameter that fits inside the rotary ring 14 is provided, and this outer plug 17 has a wavy peripheral wall 18 vertically provided on the outer peripheral edge corresponding to the wavy stepped portion 16, and a cylinder at the center of the lower surface. A shaped plug 19 is provided vertically. . The plug body 19 is formed to have a slightly larger diameter than the spout 6 of the inner plug 4, and is press-fitted into the spout 6 to close the spout 6. It has an annular projection 20 that fits and locks into the annular groove 7, and the outer plug 17 is fitted and locked into the rotary ring 14 by engagement between the annular groove 7 and the annular projection 20. .

Further, a second rectangular cylinder 21 facing the first rectangular cylinder 12 is provided on the lower surface of the outer plug 17 surrounding the plug body 19. It is formed to be slightly smaller than the first rectangular cylinder 12, and the outer corner of the lower end is chamfered to form a second inclined surface 22 that comes into contact with the first inclined surface 13.

When the outer plug 17 is fitted into the rotary ring 14, the second rectangular cylinder body 21 fits into the first rectangular cylinder body 12, positions the outer plug 17, and externally Functions as a stopper for the stopper 17,
At this time, the wavy stepped portion 16 is aligned and meshed with the wavy peripheral wall 18.

Then, when the rotation ring 14 is turned, the wavy stepped portion 1
6 pushes the wavy peripheral wall 18 and pushes up the outer plug 17, so that the annular protrusion 20 of the plug body 19 comes off from the annular groove 7, and the plug body 19 comes out of the spout 6 and comes out of the rotating ring 14, and pours out. Exit 6 opens.

In addition, as a means for locking the outer plug 17 within the rotation ring 14 with the spout 6 closed, in this embodiment, an annular groove 7 is provided inside the spout 6, and an annular protrusion 20 is provided on the plug body 19. However, the invention is not necessarily limited to this, and the annular protrusion 20 and the annular groove 7 may be provided so as to fit into the inner surface of the rotating ring 14 and the outer surface of the wavy peripheral wall 18, respectively. An engaging portion that engages the cylinder 12 and the second rectangular cylinder 21 in a concave and convex manner may be provided.

In this embodiment, the plug 19 is formed into a cylindrical shape and is press-fitted into the spout 6 to close the spout 6. In order to close the spout 6, the plug 19 is inserted into the nozzle. Nozzle 5 is formed with a larger diameter than Nozzle 5.
The spout 6 may be closed by covering the tip of the spout.

Furthermore, the inner plug 4 and the cap main body 8 do not need to be separate bodies, and may be formed integrally.

[Effect of idea]

According to the present invention, the spout 6 can be easily opened because the outer plug 17 can be removed by simply turning the rotary ring 14. Also, in order to close the spout 6, the outer plug 17 must be inserted into the rotary ring 14. Since it is only necessary to fit them together, the operation is extremely easy and user-friendly.

In addition, when the spout 6 is closed, the outer stopper 17 is housed within the rotating ring 14, so even if the container 1 is knocked over or dropped, the outer stopper 17 will remain inside the rotating ring 14.
4 and prevents unnecessary loads from being applied, so it will not come off and the contents will not spill.
