Description

[Detailed description of the invention] Industrial application field This invention relates to a crown used to open and close bottles containing alcoholic beverages, etc.

BACKGROUND TECHNOLOGY Conventionally, this type of crown has been used as
The one shown in the figure is used.

In the figure, reference numeral a designates a cap made of synthetic resin, and a tongue piece b used for pushing up when opening is provided on a part of the outer periphery of the cap. The cap a is formed integrally with the seal portion d via a circumferential thin groove portion c. e is a knob for cleaving the groove c, the proximal end f of which is provided on the upper part of the sealing part d, and the knob e covers the front surface directly below the tongue b; It is connected to the tongue piece b by a plurality of connecting pieces g.

Note that a space i is formed between the tip h of the knob e and the seal portion d in order to make it easier to pick the tip h.

A protrusion j is formed on the inner surface of the cap a, and the cap a is brought into pressure contact with the recess of the bottle k shown in FIG.

When opening the crown formed in this way and attached to the bottle k, first grasp the tip h of the knob e and pull it outward to tear the connecting piece g, and then tear the groove c. Then, separate the cap a from the seal part d, remove the cover of the tongue b by the knob e, push up the lower surface of the tongue b, and open the cap a.
to open.

Cap a is opened as described above, so if the contents of the bottle are tampered with by opening the cap, the above-mentioned tampering will be exposed because the connecting piece g has been torn. It's getting old.

Problems to be solved by the invention However, the conventional crown described above has the following drawbacks. It is done by immersing this crown in hot water and heating it.
Then, as shown in FIG. 4, the space i formed between the tip h of the knob e and the seal part d is
This is because if a force is applied diagonally upward to the tongue piece b using a screwdriver m or the like from the portion , the crown can be opened without the connecting piece g breaking.

This invention was made in order to solve such problems, and its purpose is that the cap a and the seal part d are integrally provided through the circumferential groove part c, as described above, and the cap a In the crown, a tongue piece b for pushing up is provided, a knob e is provided at the sealing part d by its base end f, and the knob e covers the front surface directly below the tongue piece b. It is an object of the present invention to provide a crown that cannot be opened illegally, as shown in the above-mentioned conventional example, even when using a tool such as a screwdriver m or the like.

Means for Solving the Problems This invention which achieves the above object is described as follows: A cap formed of synthetic resin and a cylindrical seal part are connected vertically and through thin grooves in the circumferential direction. In the crown, which is integrally formed, a weakened line is formed from the lower end of the seal part to the groove part, and a tongue piece protruding radially outward is provided on a part of the outer periphery of the cap. A proximal end of a knob for tearing the groove is provided on the upper part, and the knob covers the front surface directly below the tongue piece, and the tip of the knob is attached to the upper part of the sealing part via the connecting piece. It is a crown that is connected in one piece.

Function: A user such as a consumer grasps the tip of the knob and pulls it outward to tear the connecting piece, then tears the groove and weakened line to remove the sealing part, and pushes up the tongue piece. Open the cap.

In addition, if the opening is made other than the regular opening by a consumer or the like as described above, the opening will be exposed because the connecting piece is torn.

Next, when an attempt is made to open this crown illegally, as shown in the prior art example, when a screwdriver or the like is used to push up the tongue, the driver is inserted between the tip of the knob and the seal. The connecting piece is broken, thereby exposing unauthorized opening.

Embodiment In FIGS. 1 to 3, reference numeral 2 denotes a synthetic resin cap, and a tongue piece 1 used for pushing up when opening is provided on a part of the outer periphery of the cap. The cap 2 is formed integrally with the seal portion 3 via a thin groove portion 4 formed in the circumferential direction.
5 is a weakened line formed from the lower end of the seal portion 3 to the groove portion 4, which is a thin groove portion;
It consists of holes etc.

A proximal end portion 7 of a knob 6 for tearing the groove portion 4 is integrally provided in the seal portion 3, and the knob 6 covers the front surface directly below the tongue piece 1, and its tip portion 8 is Connecting piece 9 that is easily torn
It is connected to the upper part of the seal part 3 via.

In addition, 11 is a rib, 12 is a protrusion, 13 is an inner cylinder, 1
Reference numeral 4 indicates a hole constituting a part of the weakened line 5, 15 indicates a bottle, and 16 indicates a gap. As shown in FIG. 1, the knob 6 has the largest diameter at its approximately central portion 17, and is formed in a shape that surrounds approximately half of the knob. 18 indicates a bent portion.

Effects of the invention This invention is constructed as described above, in which a synthetic resin cap and a sealing part are formed vertically and integrally through a thin-walled groove, and a tongue piece is provided on a part of the outer periphery of the cap. In the crown, a weakened line is formed from the lower end of the seal part to the groove part, and a proximal end part of a knob for tearing the groove part is provided at the upper part of the seal part, and the knob covers the front surface directly below the tongue piece. The tip of the knob is integrally connected to the upper part of the seal through the connecting piece, so that unlike the conventional device, a screwdriver or the like can be inserted between the tip of the knob and the seal, and the tongue can be removed. If an attempt is made to push up the piece, the connecting piece will be broken by this driver or the like. Therefore, unauthorized opening is exposed due to this broken connection piece. In this way, this invention can provide a crown that can detect unauthorized release.
