[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap device for a container, which is devised so that the tightening position of the cap can be identified by sound and also has a tamper-proof function.

[0002]

[Prior Art]

 If the screw type cap is not tightened as specified, the airtightness may be incomplete and moisture may enter. Also, if you tighten it too hard, it may be difficult to open it or the cap may crack.

Therefore, in order to secure the proper tightened state, (a) a leaf spring with a sound is attached to the cap, a sound is generated by the displacement of the leaf spring, and a predetermined tightening is performed with this sound. The one that makes it possible to check whether or not it has been broken, or the one that makes a mark on the (b) cap and the container side and that the specified tightening is made by aligning these marks. Etc. are known.

[0004]

[Problems to be solved by the device]

 However, in the case of the above-mentioned means (a), complicated processing is required to incorporate the leaf spring into the cap, which causes a problem of increasing the manufacturing cost and does not notice it because a single noise is not produced. There is. In addition, in the case of the method (b), it is necessary to check the contents at a glance, which is especially inconvenient for the blind.

An object of the present invention is to provide a cap device which can be easily recognized by making a sound several times at the time of proper tightening and which has a function of preventing tampering.

[0006]

[Means for Solving the Problems]

 The structure of the present invention is as follows.

A tamper-proof band fitting groove is formed on the outer periphery of the base of the mouth of the container, and a fitting part that fits into the tamper-proof band fitting groove and is prevented from rotating is formed in the lower half of the inner surface. Tamper-proof band formed by forming protrusions on part of the inner surface upper part, and the lower edge enters into the above-mentioned tamper-proof band with a gap, and a continuous chevron is formed on part of the outer edge of the lower edge to prevent the above-mentioned tamper-proof. A container cap device consisting of a cap formed integrally with the tamper-proof band side so that the band-side protrusion is located and connected to a part of this continuous chevron.

A packing is usually provided on the inner surface of the cap. In order to secure sufficient elasticity, deformation width, and seal of this packing, it is advisable to provide corrugated unevenness on the upper surface so that proper tightening can be obtained no matter how many times it is opened and closed. A desiccant storage chamber may be formed in the center of the packing.

[0009]

[Action]

 Since the cap is molded integrally with the tamperproof band, tighten it into the mouth of the container as it is, and at the position where the predetermined tightening has been performed, the mating part on the tamperproof band is the tamperproof band on the container side. Fit in the fitting groove. In this state, both the tamper proof belt and the cap are prevented from rotating with a certain force and cannot be opened.

Next, in order to open the cap, when the cap is pinched and turned, the tamper-proof band does not rotate because it fits in the fitting groove on the container side, and the tamper-proof band does not play against the cap. It is torn off at the tip of the protrusion that is integrally connected to the prevention band. After that, you can open the cap by turning the cap as it is.

Next, the cap is tightened again to close it, and when it comes to the proper tightening position, the protrusions on the tamper-proof band engage the continuous chevron on the cap side. There are several popping sounds. From this sound, it can be seen that proper tightening was performed.

【Example】

 FIG. 1 is an exploded perspective view of a cap device according to the present invention, in which 1 is a container, 2 is a mouth of the container 1, 3 is a base portion of the mouth 2, and 4 is a tamper-proof band fitting formed on an outer peripheral surface of the base portion 3. The dowel groove 5 is a screw screw.

Reference numeral 6 denotes a ring-shaped tamper-proof band formed by forming a fitting portion 7 for fitting in the fitting groove 4 on the inner surface and forming a mountain-shaped protrusion 8 on the upper inner surface, and 9 as a cap, A screw screw 10 that is screwed into the screw screw 5 is formed on the inner surface of the cap 9, and a continuous chevron 12 is formed on the lower end outer peripheral surface of the skirt portion 11 in a continuous manner. Although the tamper-proof band 6 and the cap 9 are separated from each other in FIG. 1, they are integrally formed in a state in which the tips 8'of the protrusions 8 are connected in series to a part of the valley in the continuous chevron 12. (Injection molding), there is a gap for the length of the protrusion 8 between the skirt portion 11 and the inner surface of the tamper-proof band 6.

Reference numeral 13 is a packing, and a ring-shaped corrugated (concave and convex) 15 is formed on an upper surface 14 ′ of a peripheral edge 14 of the packing 13, and a storage chamber 16 for silica gel 17 is formed in the center. There is.

In the above embodiment, the projection 8 and the continuous chevron 12 are formed at two locations on the circumference, but there may be more, for example, three to four locations.

In the cap device, since the tamper-proof band 6 and the cap 9 are integrally molded as described above, the packing 13 is inserted into the cap 9 and initially tightened in the mouth 2 of the container 1 in this state. .. When a predetermined amount of tightening is performed, the fitting portion 7 of the tamperproof band 6 fits into the fitting groove 4 on the container 1 side, and thus tightening is stopped in this state. This state is shown in FIG.

The screw screws 5 and 10 are designed so that proper tightening is performed in this fitted state, and the corrugation 15 of the packing 13 is also crushed appropriately.

When the cap 9 is first opened, it is necessary to rotate it with a strong force because the tamperproof band 6 and the cap 9 are connected by the tip 8 ′ of the protrusion 8. When the cap 9 is rotated in the direction of arrow a in FIG. 3 by this strong force, the tip 8'of the protrusion 8 is torn off between the cap 9 side. After that, all you have to do is turn the cap 9 and open it.

Next, when the cap 9 is closed, the screw screws 5 and 10 are aligned and tightened in the direction of the arrow b in FIG. 4, and eventually the tip 8 ′ of the protrusion 8 is caught on the continuous chevron 12, When you get over this, you will hear several repellants. The user can know that the proper tightening has been performed by this repellency sound.

[Effect of the device]

 The cap device according to the present invention has the above-described structure and operation, and has the following effects.

A. A continuous chevron is formed on the cap side, and a protrusion is formed on the tamper-proof band side.The both are integrally molded in a state where the protrusion is located inside this continuous chevron, and the cap of the container is tightened in this state. The fitting part of the tamper-proof band is now fitted into the fitting groove on the container side at the proper position.

As a result, when the cap is once opened and then tightened to close the cap, the tips of the protrusions are caught in a continuous chevron shape, and a repellant sound is generated several times. Exactly this repellency is the proper position where the cap is first tightened.

Therefore, since the proper tightening position can be known by the repelling sound of several times, it is very convenient and is not heard.

B. Since the cap that makes a repellant sound several times at the proper tightening position is molded integrally with the tamperproof band, it is possible to obtain the two functions of setting the proper tightening position and preventing tampering with a simple and inexpensive structure. You can

C. By forming the corrugations on the upper edge of the packing, the tightening amount can be widened and the seal performance can be maintained for a long time.
