BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The container of the present invention comprises a container body 1, a cap 2, and a stopper 3 attached to the cap 2 and providing the cap 2 with a virgin seal function.

The container body 1 has a mouth-and-neck portion 10 having a thread formed on the outer surface thereof from the upper end of the body via a shoulder portion 4 and an engaging element 7 standing up and down from the shoulder portion 4 in the circumferential direction. The engaging element 7 has a saw-like shape in which an inclined surface 5 that gradually rises 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 hanging 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 and neck from the inside. The stopper 21 inscribed on the inner peripheral surface of the portion 10 is suspended, and the outer peripheral wall 9 is
An arc-shaped mounting hole 12 is opened in a part of the top plate 8 in the circumferential direction between the mounting peripheral wall 11 and the outer peripheral wall 9 and a lower ring 16 is fixedly engaged with a lower portion of the mounting peripheral wall 11.

The lower ring 16 has an inner ring body 13 fitted and fitted on the lower outer surface of the mounting peripheral wall 11 and an outer ring body fitted and fitted on the lower inner surface of the outer peripheral wall 9 and opposed to the inner ring body 13 through a narrow gap. The ring body 14 is integrally connected with a circumferentially continuous jumping bar 15 and is attached after the stopper 3 is mounted on the cap 2. The engagement ridge on the outer surface of the outer ring body 14 is engaged with the inner surface of the lower part of the outer peripheral wall 9. Engagement and fixation is achieved by engaging with the concave groove.

The stopper 3 is provided with a disk-shaped knob 18 having both sides recessed from the center of the upper end of a flat and slightly curved body piece 17 that can pass through the mounting hole 12 and stands up like a head.
Further, short arms 19, 19 inclined outward and downward from both sides in the circumferential direction of the torso 17 are hung down, and a foot 20 which inclines from the lower end edge of the torso 17 in the same direction as the inclined surface 5 of the engaging element 7 is provided. , 20 are suspended.

The stopper 3 is mounted on the cap 2 through the mounting hole 12 before the lower ring 16 is mounted. That is, with the knob 18 as the head in the mounting hole 12 from below,
9 and 19 are pushed in until they are pressed into engagement with both circumferential edges of the mounting hole 12.

Thereafter, the lower ring 16 is attached to the cap 2 so that the stopper 3 hanging down to the engaging element 7 is formed.
The legs 20, 20 are sandwiched between a pair of inner and outer ring members 13, 14, and are positioned in the engagement portion 7 with their radial movement suppressed.

When the arms 19, 19 are forcibly pulled up via the knob 18, they come out of the mounting holes 12, whereby the entire stopper 3 can be removed from the mounting holes 12.
Since 19 and 19 are short and have an appropriate elasticity, it is difficult to bend manually, and once pulled out, the arms 19 and 19 cannot be inserted again from outside (above) by pushing them into the mounting holes 12. .

In this embodiment, the cap 2 is attached to the container body 1 by screwing the peripheral wall 11 to the outer surface of the mouth and neck 10 like a normal cap. That is, since the feet 20, 20 are inclined in the same direction as the inclined surface 5 of the engagement element 7, the feet 20, 20 are inclined.
Can be screwed in because it is elastically deformed and easily gets over the engaging element 7. On the other hand, when the opposite cap 2 is removed, the feet 20 and 20 cannot be turned back because the feet 20 and 20 stop against the upright surface 6 of the engagement element 7.

If the consumer forcibly pulls out the stopper 3 with the knob 18, the locked state by the stopper 3 is released, so that the cap 2 can be turned back and removed from the opening of the container body 1.

Once the stopper 3 is pulled out, the arms 19, 19 cannot be bent manually, and therefore cannot be mounted in the mounting hole 12 from the outside again, and have a so-called virgin seal function.

According to the above-described embodiment, the virgin seal stopper 3 can be attached by pressing it into the attachment hole 12 of the cap 2 from below, and does not require mechanical force such as a jig. Further, the pull-out of the stopper 3 is possible by an instantaneous operation because the arms 19, 19 are short, and the handling for the consumer is simple and easy.

[0025]

As described above, in the container of the present invention, an arc-shaped 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 surrounding the cap 2. Through a pair of arms 19, 19 inclined outward and downward at both ends in the direction,
Once pulled out, a virgin seal stopper 3 that cannot be attached from the outside again is pushed in from below and engaged by pressing and pressing, while the foot 20 of the stopper 3 is inclined in a predetermined direction, and stands on the shoulder 4 of the container body 1. The cap 2 has a virgin seal function, and the stopper 3 has Since it can be easily attached by human power without requiring mechanical force of a jig or the like, and can be easily and easily removed, it is advantageous in handling.
