Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a cap equipped with a pilfer-proof member.

``Prior Art'' Conventionally, a type of cap that seals the mouth of a bottle has been equipped with a pilfer-proof member to confirm whether the bottle is unopened or has already been opened. are provided.

The general structure of caps with pilfer-proof members is a metal cap body made of aluminum or the like, and a pilfer-proof cap made of soft synthetic resin such as low-density polyethylene resin, soft PVC resin, or EVA resin. It has a structure that includes several parts.

FIG. 5 is a diagram showing an example of a metal cap equipped with a conventional soft synthetic resin pilfer-proof member.

In FIG. 5, reference numeral 1 is a cap, and reference numeral 2 is a bottle mouth. This cap 1 is the cap body 3
and a pilfer-proof member 4. This cap body 3 includes a cylindrical tube portion 5,
It is comprised of a top plate part 6 that closes the upper opening side of this cylindrical part 5. The cylindrical part 5 has a thread rolled by a roll-on roller (RO roller) that engages with the external thread 7 threaded on the bottle mouth 2, and the lower part of the cylindrical part 5 has a convex shape. A projecting portion 8 is formed. The pilfer-proof member 4 has an annular attachment ring 9 and an annular pilfer-proof ring 10. Bridge 11, 11...
. . . and large diameter stems 12, 12 . . . . When the cap 1 is opened, the pilf-proof ring 10 is attached to the pilf-proof ring 10.
Vertical score 13 for cutting 0,
Bottle opening 2 is placed inside the pilfer proof ring 10.
Locking tongue pieces 14, 14, . . . for locking are formed. The attachment ring 9 is fitted inside the protrusion 8 at the lower part of the cylindrical part 5, thereby attaching the pilfer-proof member 4 to the lower part of the cap body 3. A step portion 15 for locking the pilfer-proof ring 10 is formed on the lower outer surface of the bottle mouth 2.

When opening the bottle spout 2 to which the cap 1 is attached, the cylindrical portion 5 is rotated in the opening direction relative to the bottle spout 2. Then, the cylinder part 5 rises, but since the pilfer-proof ring 10 is locked to the step part 15 of the bottle mouth 2, its rise is prevented. Then, when the cylinder part 5 is further rotated, the bridge 1
1,11...and vertical score 13,1
3... is disconnected. As a result, the pilfer-proof ring 10 is attached to the mounting ring 9 with the stem 1
It is divided into several arc-shaped pilfer-proof ring pieces connected only at 2, 12..., and the bottle mouth 2
The opening of the package will be confirmed.

``Problem that the invention attempts to solve'' The cap 1 described above is designed so that when the cap 1 is opened and screwed back onto the bottle opening 2, the separated pilfer-proof ring pieces are pulled outward from the bottle opening. Even if the pilf-proof ring 10 is divided into several pilf-proof ring pieces when the cap 1 is opened, these pilf-fure-proof ring pieces is pilfer proof ring 10
In the divided state, it is located along almost the same circle as the circle formed by the pilfer-proof ring 10 before being divided, and the pilfer-proof ring piece and the cap body 3 are separated. The positional relationship is almost the same as the positional relationship between the pilfer-proof ring 10 and the cap body 3 before being separated, so when the cap 1 from which the pilfer-proof ring 10 has been separated is reattached to the bottle opening 2, There was a drawback that it was difficult to determine whether the bottle opening 2 was an unopened bottle or an already opened bottle.

The problem in this invention is how to create a cap that can be easily distinguished as unopened or already opened.

"Means for Solving the Problem" This invention is based on the fact that an annular pilfer-proof member made of synthetic resin is attached to the lower part of a cap body formed in a cylindrical shape with a bottom. In a cap consisting of an attachment ring fixed to the main body and a pilfer-proof ring equipped with an annular locking tongue that serves as a locking part to the bottle mouth, a cap is provided above the upper end of the locking tongue. The device is characterized in that a protruding plate-shaped push plate is connected to the locking tongue.

``Effect'' After removing the cap of this invention from the bottle mouth,
When screwed onto the bottle spout again, the push plate connected to the locking tongue comes into contact with the outer circumferential surface of the stepped part of the bottle spout, and the push plate is pushed by the stepped part of the bottle spout, causing the pilfer-proof ring piece to Projected outward.

"Embodiment" FIGS. 1, 2, 3 and 6 are diagrams showing an embodiment of this invention.

In these figures, the same elements as those shown in FIG. 5 are given the same reference numerals, and their explanations will be omitted.

The cap 1a described here is different from the cap 1 shown in FIG. A push plate portion 19 consisting of supporting portions 18, 18 is provided to support the locking tongue piece 14 at a predetermined position, and the push plate 17 is in a state in which a part of it projects above the upper end of the locking tongue piece 14. The point is that it is arranged.

The push plate portion 19 is formed by a portion of the locking tongue piece 14 bulging outward in the radial direction. This push plate portion 19 is a rectangular push plate 1
7 is supported by triangular plate-shaped support parts 18, 18. The push plate 17 extends upward from the cap 1a between the radially outer surface 16 of the locking tongue 14 and the radially inner surface of the pilfer-proof ring 10.
A portion thereof protrudes above the upper end of the locking tongue piece 14. The push plate 17 has the cap 1a connected to the bottle opening 2.
When the bottle is attached to the bottle, its upper end comes into contact with the stepped part 15 of the cap 1a, and the upper part of the push plate 17 is pressed against the stepped part of the bottle opening 2, as shown in FIG. The pilfer-proof ring 10 is bent and placed in the cap 1a with the pilfer-proof ring 10 biased radially outward of the cap 1a. The above push plate part 19
is formed at one location on each of the pilfer-proof ring pieces 20, which are formed by dividing the pilfer-proof ring 10 into several pieces when the cap 1a is opened.

When opening the bottle spout 2 to which the cap 1a is attached, the cylindrical portion 5 is rotated in the opening direction relative to the bottle spout 2. Then, the cylindrical part 5 rises, but the pilfer-proof ring 10 moves to the stepped part 15 of the bottle mouth 2.
Since it is locked to, its rise is prevented. Then, when the cylinder part 5 is further rotated, the bridge 1
1,11...and partical score 13,1
3... is disconnected. This allows the pilf-proof ring 10 to be attached to the mounting ring 9 on the stem 1.
It is divided into several arc-shaped pilfer-proof ring pieces 20, . . . which are connected only at 2, 12 .

When attaching the opened cap 1a to the bottle spout 2 again, the push plate portion 19 fixed to the divided pilfer-proof ring pieces 20, . . .
As shown by the solid line in FIG.
0, ... toward the outside in the radial direction of the cap 1a. As a result of this pressing, the pilfer-proof ring pieces 20, . . . are attached to the stem 1 as shown in FIG.
The cap 1 protrudes from one end on the second side toward the other end, which gradually opens outward in the radial direction of the cap 1. This confirms that the bottle opening 2 has been opened.

The above-mentioned cap 1a is provided with the push plate part 19 that urges the pill-proofing ring 10 radially outward of the cap 1a. When the push plate 17 is pushed by the step part 2 and the cap is opened, the pilfer-proof ring piece 2 is separated.
0,... are pushed outward. As a result, the pilfer-proof ring piece 20 is pushed radially outward of the cap 1a and protrudes as described above, making it possible to reliably determine whether the cap 1a is unopened or has already been opened. can be done.

Further, since the push plate portion 19 is formed to bulge outward from the locking tongue piece 14 in the radial direction in a shape such that the lower portion of the push plate 17 is supported by the two supporting portions 18, 18, the locking Since the positional stability of the pusher plate 17 with respect to the tongue piece 14 is good, the repulsive force of the pusher plate 17 can be strengthened, and the action of the pusher plate 17 to urge the pilf-proof ring piece 20 outward can be prolonged. It can last for a period of time.

FIG. 4 is a diagram showing another embodiment of this invention. The cap 1a of the above-mentioned embodiment has a push plate 1
7 is fixed by two supporting parts 18, 18 and is integrally fixed to the locking tongue piece 14, but the cap 1b according to this embodiment A rectangular push plate 17 is formed to protrude upward.

In the cap 1b configured as described above, the pushing plate 17 urges the pill-proofing ring piece 20 outward so that it can be reliably determined whether the cap is unopened or has been opened. It is possible to obtain the same effects as in the above-mentioned embodiment, such as being able to maintain the action for a long period of time.

``Effect of the invention'' The cap of this invention has a plate-shaped pushing plate that protrudes above the upper end of the locking tongue and is connected to the locking tongue. When the bottle is attached to the container, the pushing plate is pushed by the bottle opening step, and when the bottle is opened, the separated pilf-proof ring pieces are pushed outward. As a result, the pilfer-proof ring piece is pushed outward in the radial direction of the cap and protrudes so as to gradually open from the stem-side end toward the other cut end. Therefore, according to the cap of the present invention, it is possible to reliably determine whether the cap is unopened or has been opened.
