BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container provided with a cap having a virgin seal function.

[0002]

2. Description of the Related Art Various types of so-called virgin seal mechanisms have been provided which have a mounting structure in which a cap cannot be reattached to its original state once removed, and which guarantee the quality of the contents.

[0003] Japanese Utility Model Laid-Open No. 2-105865 is an example of these. In this publication, an inner plug which is fitted inside the neck of the bottle from the back of the top wall of the cap body and reaches the enlarged diameter portion immediately below the neck is erected, and the lower part of the inner plug is expanded like a trumpet. The skirt part is elastically deformable by providing split grooves in the circumferential direction, and this skirt part is elastic that can not be collapsed by human power, and is forcibly applied to the bottle mouth using the mechanical force of a jig etc. It is intended to be attached in a proper manner.

In order to remove the cap, the cap is forcibly pulled out, and at this time, the skirt is removed by being compressed and deformed by the mouth and neck. Once removed, the skirt cannot be re-attached because the skirt is not pinched by human power, and a virgin seal function is obtained.

[0005]

According to the above conventional example,
Although it has the advantage of having a virgin seal function with a simple structure, it is somewhat inconvenient in that it cannot be installed unless mechanical power such as a jig is used, and the operation of pulling out the cap for consumers is also somewhat heavy. is there.

An object of the present invention is to provide a container provided with a cap which does not require mechanical force to mount a virgin seal component and which can be easily unlocked by the seal member.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The container of the present invention is a container 1, a cap 2, and a cap 2
And a push button 3 for releasing the cap 2 to remove the cap.

The container body 1 has a mouth-and-neck portion 10 having a thread formed on the outer surface thereof via a shoulder portion 4 from the upper end of the body, and an engaging element 7 standing up and down from the shoulder portion in a circumferential direction. The engaging element 7 has a sawtooth shape in which an inclined surface 5 that rises gradually in the screwing direction and an upright surface 6 that rises at once in the screwing direction are formed.

The cap 2 has an outer peripheral wall 9 suspended from the periphery of the top plate 8, a mounting peripheral wall 11 screwed to the outer surface of the mouth and neck portion 10 from the inside, and a mouth neck from the inside. The stopper 17 inscribed on the inner peripheral surface of the part 10 is suspended, and the outer peripheral wall 9 is
An arc-shaped mounting hole 12 is formed in both sides of the top plate 8 between the outer peripheral wall 9 and the mounting peripheral wall 11, and a donut-shaped transition member 15 is engaged and fixed between the outer peripheral wall 9 and a lower portion of the mounting peripheral wall 11.

The transition member 15 has a shape in which an inner ring body 18 and an outer ring body 19 are erected from the inner and outer peripheral edges of a flat donut-shaped substrate, and a window is provided at a position corresponding to the mounting holes 12, 12 of the donut-shaped substrate. The engaging claws 1, which are pivotally supported by these windows 13, 13 by means of a pivot shaft capable of twisting the middle of both sides, and which are always inclined in the same direction as the inclined surface 5 of the engaging element 7.
4, 14 are arranged rotatably.

The transition member 15 has the inner and outer ring members 18 and 19 opposed to the inner and outer surfaces of the mounting peripheral wall 11 and the lower portion of the outer peripheral wall 9 so as to be engaged with each other. It is fixed by engaging with the engaging groove on the inner periphery of the peripheral wall 9.

The push button 3 is formed by bending a rectangular flat plate so that it can be inserted into the mounting hole 12. The push button 3 protrudes serrated engagement ridges 16, 16 on both surfaces near the upper portion. Article
The heads 16 and 16 are inserted through the mounting holes 12 and 12 so as to be able to be pushed into the mounting holes 12 and 12 while leaving the head outside. In this state, the lower end surface reaches the inclined upper ends of the engaging claws 14 and 14. 20, 20 is push button 3
Is a small locking ridge that prevents spills out.

In this embodiment, since the engaging claws 14 and 14 are inclined in the same direction as the inclined surface 5 and easily get over the engaging member 7 through the torsion of the pivot shaft, the cap 2 is formed in a usual manner. By attaching the peripheral wall 11 to the mouth and neck 10 like a cap,
Can be attached to

On the other hand, when the cap 2 is removed,
Since the hooks 4 and 14 are locked on the upright surface 6 of the engagement element 7, they cannot be turned back.

Here, when the push button 3 is pushed in, the push button 3 rotates the engaging claw 14 like a seesaw to make it horizontal, so that the cap 2 is unlocked by the engaging claw 14 and the cap 2 is released. 2 can be turned back, and can be removed from the opening of the container body 1.

The pushed push button 3 is attached to the mounting hole 12.
There is no clue to return to the original state. Even if the cap 2 is removed, the pushed push button 3 cannot be pushed back because the upright surface of the serrated engagement ridge 16 abuts against the back surface of the cap 2 top plate. That is, it has a virgin seal function.

In the above embodiment, the transition member 15 for virgin seal and the push button 3 may be attached by pressing with human power, and no mechanical force such as a jig is required. Also cap 2
The lock can be released simply by pressing the push button 3, and the operation can be performed with one touch without any trouble.

In the above embodiment, there are shown two sets of examples in which the engaging claws 14, 14 for locking the cap 2 and therefore the release push buttons 3, 3 are arranged on both sides. This is because the engaging elements 7 on the shoulder 4 of the container 1 are usually arranged on both sides for convenience of molding. However, when the cap 2 is fully screwed in, the engagement claws 14 do not always have a set positional relationship with respect to the corresponding engagement members 7. In an extreme case, the cap 2 may be locked only after returning the cap 2 by half a turn.

In order to lock the cap 2 while minimizing the amount of return rotation, it is effective to increase the number of sets of the engagement claws 14 and the push buttons 3.

FIG. 2 shows another embodiment in which four engaging claws 14 are provided at 90-degree intervals, and thus four push buttons 3 are provided. In this case, since the four push buttons 3 are individually formed on the operation upper surface in terms of structure, in the illustrated example, one disc-shaped push plate 21 is shared and integrated. For this reason, the center of the top plate 8 of the cap 2 is recessed 22, and when the push plate 21 is pushed in, the push plate 21 is buried in the recess 22.

Needless to say, as long as the positional relationship between the engaging members 7 and 7 when the cap 2 is fully screwed can be determined in advance, the engaging claw 14 and the push button 3 may be one set.

[0027]

As described above, in the container of the present invention, a mounting hole 12 is formed in the top plate 8 between the mounting peripheral wall 11 of the cap 2 and the outer peripheral wall 9 and a donut-like shape is formed between the lower portions of the peripheral walls 11 and 9. The transfer member 15 is engaged and fixed, and a portion corresponding to the mounting hole 12 of the transfer member 15 is passed over the serrated engagement element 7 on the shoulder portion 4 of the container body 1 when the screw is advanced, but is locked when the screw is retracted. The inclined engaging claw 14 is formed rotatably, and the mounting hole 12
The cap 2 has a virgin seal function because the push button 3 for unlocking the cap 2 is unlocked by pushing the push button 3 to release the lock of the cap 2 when pressed. The transfer member 15 and the push button 3 of the parts for use can be easily attached by human power without requiring mechanical force such as a jig, and the cap 2 can be easily removed, so that handling can be greatly simplified.
