れる容器のキヤツプ装置に関する。[Detailed description of the invention] [Industrial application field] This invention relates to a cap device for a container storing industrial chemicals, etc., and in particular, once the cap is screwed onto the mouth of the container and fitted, the cap becomes non-retentive. The present invention relates to a capping device for a container.

Conventionally, as this type of cap device, many devices generally referred to as threaded caps have been on the market. This means that when the cap is screwed and tightened into the threaded opening, the threaded rupture cylindrical part formed integrally with the cap engages with the latching part formed at the proximal end of the outer periphery of the opening. It is designed to be latched and prevented from rotating (returning). When removing the cap from the mouth in order to take out the contents of the container, the cap is forcibly turned in the opposite direction to the direction in which it is fastened to the mouth, thereby breaking the breakable cylindrical part as if threading it away from the cap. . The cap can now be rotated smoothly relative to the mouth and removed.

の犯罪の発見などにも有効である。 With such a structure, when the cap is completely unopened, the cap is held against the opening by the threaded and broken cylinder part, and does not come off unnecessarily. In addition, if the cap is forcibly removed from the mouth of the container in its unopened state, the threaded break tube that was integrally provided on the cap will break as if it had been threaded, but the cap itself will then be screwed back into the mouth. Can be used repeatedly by tightening and fitting. Of course, when the cap was re-fitted, the broken tube part was in a broken state where it had lost its anti-rotation function, so there remained the fact that the cap had been opened by someone at least once, and something was not done. It's convenient. For example, it is effective in extracting the contents and detecting crimes such as contamination with harmful substances.

However, in the configuration of the conventional threaded cap described above, the threaded broken cylindrical portion that prevents the cap from rotating is integrally formed as described above, so that when the cap is removed from the unopened state, the broken cylindrical portion It looks bad because it is stuck in a broken state or there are traces of breakage, and
Since it is not possible to restore the cap to its original, unopened state and reuse it, the current situation is that the cap is simply thrown away after the contents of the container are consumed, and new contents are stored inside the container. When closing the opening, a completely new cap with a threaded and broken cylindrical portion must be used each time, which is extremely wasteful.

This container capping device was devised in view of the above circumstances, and in order to solve the conventional problems,
An opening protruding from the container and having a thread formed on the outer surface of the circumferential wall, an annular lock ring that is fitted around the outer periphery of the base end of the circumferential wall of the opening, and a screw thread formed on the inner circumferential surface of the circumferential wall. a cap that is formed with a ridge and is screwed and tightened onto the outer periphery of the mouth, and the outer periphery of the proximal end of the peripheral side wall of the mouth and the lock ring fitted therein have protrusions and recesses for preventing rotation that engage with each other. A latching portion is formed, and the lock ring is formed with a breakable portion that is breakable through a thin-walled connecting portion in a part of the circumference, and a cap detent that protrudes from the broken portion. A claw is formed on the open end of the circumferential wall of the cap, and once the cap is screwed and tightened to the mouth, it is hooked to the cap detent claw of the lock ring to prevent reverse rotation. A large number of ratchet pawls are formed, which push the detent pawl and break the fractured portion of the lock ring via the thin connection portion when rotation is forcibly performed.

With the above configuration, the lock ring can be fitted to the outer periphery of the base end of the mouth of the container in a non-rotating state, and when the cap is then screwed and tightened to the outer periphery of the mouth, the latch claw at the open end of the cap will lock. The cap is hooked onto the cap detent pawl of the lock ring to prevent reverse rotation, thereby preventing the cap from coming off unnecessarily. The cap is now in an unopened state, and when the cap is turned in the opposite direction to the direction in which it is forcibly tightened against the opening, the ratchet pawl pushes the detent pawl and pulls the broken part of the lock ring against the thin connecting part. This causes the locking ring to separate from the mouth and lose its ability to prevent the cap from rotating, allowing the cap to be smoothly removed from the mouth. Here, the cap and lock ring are not integrated as in the past, but are separate bodies from the beginning, so even after the cap is opened as mentioned above,
Only the locking ring will break, and the cap itself will not leave breakage marks or look bad, and it can be refitted into the mouth as it is, and the cap can be used as a small piece without having to throw it away. By simply replacing and replenishing only the locking ring, it can be reused and can be fitted into the mouth of the container in a locked state (initial unopened state), making it very economical.

が形成されている。 The lock ring 3 is made of a synthetic resin integrally molded product, and has an annular shape as a whole, but includes a ring main body 3a extending approximately four-fifths of the circumference;
A broken piece part 3d is connected to the ring main body 3a at both ends via thin-walled connecting parts 3b and 3c which can be broken relatively easily, and is interposed in a short part where the ring main body 3a does not exist. The proximal end 2c of the mouth 2 is fitted around the outer periphery of the proximal end 2c, and a concave hook 3e for preventing rotation is formed on the inner peripheral surface of the ring main body 3a. The portion 2c is fitted with a convex hook portion 2d on the outer periphery to prevent rotation. Also, on the inner side of one end of the broken portion 3d of the lock ring 3, there is a cap detent pawl 3f projecting diagonally upward.

り回らないようになつている。 The cap 4 has a thread 4b formed on the inner circumferential surface of the circumferential wall 4a, so that the open end side of the circumferential wall 4a abuts against the lock ring 3 fitted on the outer periphery of the proximal end 2d of the mouth portion 2. It is configured such that it can be screwed and tightened onto the outer periphery of the mouth portion 2 until it is fitted.
Further, on the open end side of the circumferential wall 4a, a large number of right triangular ratchet claws 4c are formed on the inner periphery so as to protrude downward in the same direction and at equal pitches in the circumferential direction, and these ratchet claws 4c When the cap 4 is rotated in the tightening direction with respect to the mouth portion 2, it passes over the cap detent pawl 3f of the lock ring 3 one after another, and when rotated in the opposite direction, the detent pawl 3
F is hooked to the broken piece 3 to which the claw 3f is attached.
d cannot be rotated unless it is broken through the thin connecting portions 3b and 3c.

きる。 In the case of a cap device for a container having the above-mentioned structure, the lock ring 3 is first fitted to the outer periphery of the proximal end 2c of the mouth 2 of the container 1 in a non-rotating state, and then the cap 4 is attached to the mouth 2. It is fitted by screwing and tightening around the outer periphery. With this, the latch claw 4c on the side of the open end of the cap 4 is engaged with the cap detent claw 3f of the lock ring 3, preventing reverse rotation and preventing it from coming off unnecessarily. This leaves the container 1 in a completely unopened state and protects the contents of the container 1.

らスムーズに取り外せるようになる。 When removing the cap 4 in order to take out the contents of the container 1 in such a state, the cap 4 is forcibly turned strongly in the opposite direction to the direction in which it is tightened against the mouth portion 2. This force causes the latch pawl 4c of the cap 4 to engage the detent pawl 3f of the lock ring 3 and push it back, causing the broken portion 3d of the lock ring 3 to break at the thin connecting portions 3b and 3c, causing the ring to become a main body. It falls off from 3a. As a result, the lock ring 3 is separated from the base end 2c of the mouth portion 2 with only the ring main body 3a, and loses its function of preventing the cap 4 from rotating. The cap 4 is now free to rotate and can be smoothly removed from the opening 2.
ここで上記キヤツプ４はもともとロツクリング

被嵌して再利用が可能となる。 Here, since the cap 4 is originally separate from the lock ring 3, even if it is removed from the mouth 2 as described above, only the lock ring 3 will break, and the cap 4 itself will leave breakage marks etc. It does not deteriorate and can be inserted into the mouth again as it is. In addition, instead of throwing away the cap 4, you can replace and replenish only the locking ring 3, which is a small part, with a new one, so that it can be reused by fitting it into the opening of the container (initial unopened state). It becomes possible.

Since this idea was developed as described above, the cap can be inserted into the opening with a locking ring to prevent it from unnecessarily coming off, and if the cap is forcibly turned, only the locking ring will break and the cap will rotate. The lock is released and the cap can be opened smoothly, and once the cap has been opened, it can be reused in a good manner. By simply replacing and refilling only the lock ring, which is a small part, the cap can be opened again. It is possible to set the container in a closed and unopened state, eliminating the waste of throwing away the cap, resulting in a very economical container cap device.
