Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container provided with a cap having a virgin sealing function.

[0002]

[Prior art]

 There are various types of so-called virgin seal mechanisms that guarantee the quality of the contents by using a mounting structure that prevents the cap from being reattached to the original state once it has been removed.

Japanese Utility Model Laid-Open No. 2-105865 is an example of them. According to this publication, an inner plug that fits inside the bottle neck from the back of the top wall of the cap body and reaches the expanded portion directly below this neck is hung down, and the lower part of this inner plug is expanded like a trumpet. In addition, a circumferentially discrete groove is provided to form an elastically deformable skirt, and this skirt is elastic so that it cannot be squeezed manually. It is forcibly attached to.

For removal, the cap is forcibly pulled out, and at this time, the skirt portion is closed and deformed by the mouth and neck portion and removed. Once removed, the skirt cannot be manually reattached, so it cannot be reattached, and the virgin seal function can be obtained.

[0005]

[Problems to be solved by the device]

 According to the above-mentioned conventional example, there is an advantage that the virgin seal function can be provided with a simple structure, but it is somewhat inconvenient in that it cannot be attached unless mechanical force such as a jig is used, and the operation for pulling out the cap is also for the consumer. Has the disadvantage of becoming somewhat heavier.

The present invention provides a container provided with a cap that does not require mechanical force to attach the virgin seal part and that can be easily removed when opening the part.

[0007]

Means for Solving the Problems The container of the present invention has a saw tooth formed on a shoulder 4 on an inclined surface 5 that gradually rises in the screwing direction, and on an upright surface 6 that rises all at once in the screwing back direction. -Shaped engaging element 7 standing in a circumferentially discontinuous manner, an outer peripheral wall 9 from the peripheral edge of the top plate 8, and a mounting peripheral wall 11 screwed from the inside to the outer surface of the mouth / neck part 10 of the container body 11. An arc-shaped mounting hole 12 is formed in a part of the top plate 8 between the peripheral walls 9 and 11, and a pair of inner and outer rings facing the lower peripheral edges of the peripheral walls 9 and 11 at a narrow interval. A cap 2 in which a lower ring 16 in which the bodies 13 and 14 are integrally joined by a jumper rod 15 in the circumferential direction is engaged and fixed, and a flat body piece 17 that can pass through the mounting hole 12 are gripped by the head from the upper end. 18 is erected, arms 19 and 19 which incline outward and downward are hung from both sides of the body piece 17, and the inclined surface of the engaging element 7 is from the lower end of the body piece 17. It has a shape in which a foot 20 slanting in the same direction is hung down, and is pushed into a mounting hole 12 from below and both arms 19, 19 are attached to the cap 2 by press-contacting and locking both circumferential edges of the hole 12. In this state, the foot 20 is positioned at the engaging member 7 and the stopper 3 positioned by the ring bodies 13 and 14 of the lower ring 16.

[0008]

[Action]

 In the above description, the stopper 3 is attached by pushing it into the attachment hole 12 from below from the bottom until both arms 19, 19 are press-contacted to both circumferential edges of the hole 12 before attaching the lower ring 16 to the cap 2. After this, the lower ring 16 is fitted and fixed to the outer peripheral wall 9 of the cap 2 and the lower end of the mounting peripheral wall 11 by pulling out the foot 20 downward. In this state, the knob 18 is located above the top plate 8.

The cap 2 incorporating the stopper 3 is screwed and attached to the neck portion 10 of the container body 1 by the mounting peripheral wall 11.

In this case, since the foot 20 of the stopper 3 is tilted in the same direction as the inclined surface 5 of the engaging element 7, when the cap 2 is screwed, the foot 20 rides on the inclined surface 5 and moves the engaging element 7 up. Since it will get over, there is no hindrance to the screwed installation. However, the tip of the foot 20 is locked on the upright surface 6 of the engaging element 7 in the screw retraction direction and cannot be retracted. That is, the cap 2 cannot be removed.

When opening the container, the consumer holds the knob 18 and pulls up the stopper 3 forcibly. Then, the arms 19 and 19 are pulled out from the mounting hole 12, and the entire stopper 3 is pulled out from the mounting hole 12, so that the cap 2 can be removed by turning it back like a normal cap. In this case, since the arms 19 and 19 cannot be closed manually, they cannot be inserted into the mounting hole 12 again from the outside and have a virgin sealing function.

By keeping the arms 19 and 19 short, the arms can be easily pulled out and are easy to handle.

【Example】

 Referring to the drawings, an embodiment of the present invention will be described. The container of the present invention is composed of a container body 1, a cap 2 and a stopper 3 attached to the cap 2 so that the cap 2 has a virgin sealing function. ing.

The container body 1 is provided with a mouth neck portion 10 having a thread formed on the outer surface thereof from the upper end of the body through a shoulder portion 4, and an engaging member 7 standing from the shoulder portion 4 in the circumferential direction. The engagement element 7 is of a saw-like shape in which an inclined surface 5 that gradually rises in the screwing direction is formed and an upright surface 6 that rises all at once in the screwing back direction is formed.

The cap 2 has an outer peripheral wall 9 extending downward from the peripheral edge of the top plate 8, a mounting peripheral wall 11 extending downward from the inner surface thereof, which is screwed onto the outer surface of the mouth / neck portion 10, and further from the inner side thereof. An annular plug 21 inscribed on the inner peripheral surface of the portion 10 is hung down, and an arc-shaped mounting hole 12 is opened in a circumferential portion of the top plate 8 between the outer peripheral wall 9 and the mounting peripheral wall 11, and the outer peripheral wall 9 and the mounting peripheral wall are formed. 11 The lower ring 16 is fitted and fixed to the lower part.

The lower ring 16 includes an inner ring body 13 that engages with the outer surface of the lower portion of the mounting peripheral wall 11 and an inner ring body that engages with the inner surface of the lower portion of the outer peripheral wall 9 so as to face the inner ring body 13 through a narrow gap. The ring body 14 is integrally connected by a jumper rod 15 which is discontinuous in the circumferential direction. The stopper ring 3 is attached to the cap 2 after the stopper 3 is attached to the outer ring body 14. It is engaged and fixed by engaging with the engaging concave groove.

The stopper 3 has a flat and slightly curved body piece 17 that can pass through the mounting hole 12, and has a disk-shaped knob 18 that is recessed on both sides from the center of the upper end of the body piece 17 as a head. Short arms 19, 19 slanted outward and downward are hung from both upper sides in the circumferential direction, and legs 20, 20 slanted in the same direction as the slanted surface 5 of the engaging element 7 from the lower end edge of the body piece 17 are further suspended. It has a vertical shape.

The stopper 3 is attached to the cap 2 through the attachment hole 12 before attaching the lower ring 16. That is, the arms 18 are pushed into the mounting hole 12 from below with the knob 18 as the head until they are pressed and locked to both circumferential edges of the mounting hole 12.

After that, by attaching the lower ring 16 to the cap 2, the legs 20 and 20 of the stopper 3 hanging down to the engaging member 7 are sandwiched by the pair of inner and outer ring bodies 13 and 14 to move in the radial direction. It is restrained and positioned on the engaging element 7.

When the arms 19 and 19 are forcibly pulled up via the knob 18, the arms 19 and 19 come out of the mounting hole 12, and thus the stopper 3 as a whole can be removed from the mounting hole 12, but the arms 19 and 19 are short. Moreover, since it has an appropriate elasticity, it is difficult to bend it manually, and once it is pulled out, the arms 19 and 19 cannot be pushed into the mounting hole 12 from the outside (upper) and inserted again.

In this embodiment, the cap 2 is attached to the container body 1 by screwing the attachment peripheral wall 11 to the outer surface of the mouth / neck portion 10 like a normal cap. That is, since the legs 20, 20 are inclined in the same direction as the inclined surface 5 of the engaging element 7, the legs 20, 20 are elastically deformed and easily get over the engaging element 7, so that they can be screwed. On the other hand, when the cap 2 is removed on the opposite side, the feet 20, 20 are reversely attached to the upright surface 6 of the engaging element 7 and cannot be turned back.

When 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 and 19 cannot be flexed manually, and therefore it is impossible to mount the arm 19 in the mounting hole 12 again from the outside, and it has a so-called virgin seal function.

According to the above-described embodiment, the stopper 3 for the virgin seal may be attached by pressing it into the attachment hole 12 of the cap 2 from below and press-contacting it, without using a mechanical force such as a jig. Further, the stopper 3 can be pulled out by a momentary movement because the arms 19 and 19 are short, and it is easy and easy for the consumer to handle.

[0025]

[Effect of device]

 As described above, in the container of the present invention, arc-shaped mounting holes 12 are 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, and the mounting holes 12 are provided at the outer ends of the circumferential direction. Through a pair of arms 19, 19 which are inclined downward, a stopper 3 for the virgin seal, which cannot be attached again from the outside once pulled out, can be attached by pushing in from below and engaging with pressure contact, while the foot 20 of this stopper 3 is attached. It is inclined in a predetermined direction, and gets over in the screw advancing direction with the saw-tooth-shaped engaging element 7 which is erected on the shoulder portion 4 of the container body 1, but has an engaging relationship that locks in the screw retracting direction. Therefore, the cap 2 has a virgin sealing function, and the stopper 3 can be easily attached manually without requiring mechanical force such as a jig, and can be easily and easily removed, which is advantageous in handling. .
