Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cap seal for sealing the stopper of a bottle, etc., and more specifically, to a cap seal that has a function to prevent tampering (to guarantee sealing). Regarding seals.

[Prior Art] Generally, various types of closures are used to seal and protect the contents packed in bottles, and their appearance has a visually appealing design that increases product value and arouses the desire to purchase. It is usual to apply

Under such circumstances, screw caps, cork stoppers, cork stoppers with umbrellas, etc., are sometimes selected as sealing means due to the bottle shape, etc., but in this case, one of the functions of the closure is also called theft prevention. The pilfer-proof properties (sealability) cannot be guaranteed. Therefore, in the case of synthetic resins, consideration has been given to the sealability of sealing the bottle stopper by covering the bottle stopper with a decorative cap seal that utilizes heat shrinkability. In this case, in order to ensure a perfect seal and prevent the cap seal from coming off easily, the bottle stopper to which the seal is attached is usually shaped to have a step with respect to the outside diameter of the bottle mouth. Measures such as a twisted shape or a curvature shape are taken.

When opening the cap seal, use a knife or similar tool for cap seals that do not have a breakable part, or use a knife to remove only the portion corresponding to the cap for screw-on caps and other caps (for example, twist-off caps). A commonly used method is to remove the seal from the bottle stopper by breaking the broken part (generally an intermittent cut called a perforation) formed in the bottle and removing the upper part.

In this way, the sealability is maintained as long as the perforations provided in the cap seal are not torn.

Examples of these can be seen in many products, including wine products, made of synthetic resin films, or integrally molded seals.

FIGS. 10 and 11 show the prior art, and show an example in which a cap seal made of heat-shrinkable synthetic resin is applied. Reference numeral 101 indicates a stopper portion of the bottle, and reference numeral 101a indicates a narrow mouth portion. A large diameter portion 101b with an enlarged diameter is formed on the opening side of the narrow mouth portion 101a. 10
Reference numeral 2 denotes a cap seal, which covers the bottle cap part 101 and has a tongue piece 102a for cutting off in a part that covers the large diameter part 101b, and this tongue piece 10.
Perforation 102b connected to 2a and narrow opening 1
A circumferential perforation 102c is formed in a portion covering the vicinity of the large diameter portion 101b of 01a. These perforations 102b and 102c are formed with a length and pitch of about 0.3 to 1.0 mm. The length and pitch of the perforations 102b and 102c vary depending on the material and thickness of the cap seal, but they are formed so that they can be torn by holding the tongue piece 102a and pulling it with a relatively strong force. That is, first cut a perforation in the axial direction (of the container), then
The upper part can be removed by cutting out the stitches provided all around the circumference.

[Problem to be solved by the invention] By the way, in the case of the above-mentioned conventional cap seal provided with a breaking part for closure seals that are opened by twisting, the breaking part of the perforation was formed in a horizontal loop shape. If you twist the cap seal, the perforated part will be cut cleanly, and if you put it back in its original position, you will not be able to tell that it has been cut, and at first glance you will be mistaken as thinking that the packaging is in its normal state. There is a risk.

According to this conventional technology, when the difference in diameter between the large diameter part and the narrow mouth part of the bottle stopper cannot be made large due to the container design, or when the cap seal is made of heat-shrinkable synthetic resin, it is difficult to If the heat shrinkage of the synthetic resin film is not sufficient, or if the material of the synthetic resin film is soft or thin, or if the cap seal is fixed to the bottle stopper with adhesive, If it is not fixed to
After installation, the cap seal becomes easy to fall out, so as mentioned above, twist the cap seal to break the perforation, remove the upper part of the perforation from the bottle stopper, and then remove the bottle stopper and remove the contents. After stealing something or tampering with the contents, the upper part of the cap seal that has been removed is refitted to the bottle stopper and the broken perforations are aligned, the seal can be removed and the contents can be revealed. There was a problem in that it was almost impossible to tell that something had been tampered with, and the sealability was compromised.

The present invention has been made for the purpose of solving the above-mentioned conventional problems and providing a cap seal for preventing mischief that can be recognized as soon as the cap seal is twisted and a break cut such as a perforation is broken. It is.

[Means for solving the problem] The seal of the bottle stopper is released by making a break cut such as a perforation in the circumferential direction to form a break part, breaking the break part, and removing the upper part of the break part. In the cap seal for preventing mischief, the breaking cuts such as the circumferential perforations are formed so that the end portions are at different levels.

[Operation] When the cap seal is twisted to break the broken part, cracks will appear between the ends of the broken cuts such as uneven perforations, and the marks will become obvious at a glance. .

[Example] Next, the present invention will be explained with reference to the drawings.

1 to 4 show a first embodiment of the cap seal for preventing mischief of the present invention.

Figures 1 and 2 show bottle 1 using a screw cap.
These are a partially cutaway perspective view and a cross-sectional view of a case where a cap seal 3 for preventing mischief is attached to a bottle stopper 2, and the bottle stopper 2 has a screw cap 2b screwed onto the outer periphery of the opening of the narrow mouth 2a. A bead 2c for preventing the cap seal from coming off, which is the same shape or slightly larger than the screw cap 2b, is formed at the portion where the lower end of the screw cap 2b comes into contact. The upper end of the mischief prevention cap seal 3 is attached to the screw cap 2.
The outer peripheral part of the upper surface of b is engaged, and the lower end side is tightly fitted with the bead 2c extending below the cap seal removal prevention bead 2c, so as to seal the bottle stopper part 2, and the bead 2c. A fractured portion 4 is formed at a portion located on the circumferential surface of. The fracture portion 4 is formed by providing fracture cuts 5 such as perforations in the circumferential direction at a pitch of about 0.3 to 1.2 mm, and both ends are stepped. Then, in order to steal the contents of the bottle or to play a trick on the contents, if the tamper-proof cap seal is twisted and the broken part 4 is broken, the area between the two ends of the broken part 4 is shown in FIG. The item was torn like a bag and left a trace, so it was easy to see if it had been tampered with by putting it back together after it was opened.

Furthermore, reference numeral 6 denotes a breaking tongue piece 6 which is connected to the upper end side of the cap seal 3 for preventing breakage.
A perforation 7 is formed from the top toward the breaking portion 4, and when the tongue piece 6 is pulled, the breaking portion 4 is broken through the perforation 7.

Figure 5 shows the mischief prevention cap seal 3 of the present invention.
A second example is shown below. In this embodiment, the rupture part 4 is a semicircular arc-shaped rupture cut 8 formed on one side of the cap seal, and is formed on the other side of the cap seal with a step difference from both ends of the rupture cut 8. The cap seal is made up of semicircular arc-shaped fracture cuts 9, and when the cap seal is twisted, cracks will appear in two places.

FIG. 6 shows a third embodiment of the invention. In this embodiment, the fracture portion 4 includes two semicircular arc-shaped fracture cuts 10 and 12 formed parallel to each other in two stages, upper and lower, on one side of the cap seal, and these fracture cuts 1.
One semicircular arc-shaped fracture cut 1 formed on the other side of the cap seal so as to be located between 0 and 12.
It consists of 1.

FIG. 7 shows a fourth embodiment of the present invention. In this embodiment, the fracture portion 4 is a semicircular arc-shaped fracture cut 13 formed below the fracture cut 5 of the first embodiment.

8 and 9 show fifth and sixth embodiments of the present invention.
In this embodiment, the cutting portion 4 has loop-shaped breaking cuts 14, 15 formed in two stages, upper and lower, so that when the cap seal is twisted, these breaking cuts 14, 15
This shows the case where there is a cut in between.

In addition to perforations, the breaking cut may be a groove (thin linear part), and this groove can be formed by making slight lines with a cutter.

Moreover, the breaking cut may be formed so as to be located below the large diameter part of the narrow mouth part of the bottle.

[Effects] As explained above, in the mischief-preventing cap seal of the present invention, the circumferential break cuts are formed so that the ends are uneven, so if the cap seal is twisted, the edges will be uneven. If there are cracks, wrinkles, or tears between the edges of the broken cut, the traces of this will be obvious at a glance, making it easy to determine whether the seal has been broken or not, making it a safe product with excellent sealability. It has the effect of being able to provide
