Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cap seal designed to remove only the upper part of the bottle stopper, leaving the lower part for sealing the bottle stopper, such as a bottle. relates to a cap seal that has a function to prevent mischief (to guarantee sealing).

[Conventional technology]

Generally, various types of closures are used to seal and protect the contents packed in bottles, and their exteriors usually have a visually appealing design that increases product value and arouses the desire to purchase. .

Under these circumstances, cork stoppers, screw-on caps, etc. are sometimes selected as sealing means due to the suitability of the contents and the shape of the bottle. In some cases, the cork stopper or screw cap itself may not be able to provide guarantee (guarantee). In this case, a decorative cap seal is placed over the bottle stopper in close contact with consideration for sealability. In this way, cap seals are used to ensure sealing, so they are designed so that they do not come off easily.For example, the bottle stopper that the cap seal is attached to has a level difference with respect to the outer diameter of the bottle mouth. It usually has a beaded shape or a curvature shape.
The material of the cap seal has also been devised, such as by using heat-shrinkable synthetic resin or an integrally molded seal, or by attaching the cap seal to the bottle stopper with adhesive. In addition, when opening the bottle, the cap seal is designed to be removed artificially, and usually the entire cap seal is removed, or broken lines of various shapes are used to remove only the top of the bottle stopper while leaving the bottom of the cap seal. Means for opening the package, such as forming a shaped cut (hereinafter referred to as a perforation) or a groove, is provided. In this way, the cap seal is designed to ensure sealing, and the perforations and grooves that are formed make it impossible to open the seal without taking artificial means such as tearing it out.

In particular, the cap seal is designed to remove only the top part of the bottle stopper, leaving the bottom part intact. It is widely used because it allows display of the contents printed on it and advertisements to remain, and also because it is decorative for the container in general. Normally, a cap seal designed in this manner is designed so that a portion below the large diameter portion or bead portion, especially the narrow opening portion, remains.

Figures 8 and 9 show a conventional example of a cap seal designed to remove only the upper part of the bottle stopper, leaving the lower part intact. Reference numeral 1 denotes a stopper portion of the bottle, 1a a narrow mouth portion, and a large diameter portion 1b with an enlarged diameter formed on the opening side of the narrow mouth portion 1a. 2 is a cap seal which covers the bottle cap part 1 and has a tongue piece 2a for cutting at a part that covers the large diameter part 1b;
Perforation 2 in the axial direction continuous to this tongue piece 2a
b, and a circumferential perforation 2c is formed in a portion covering the vicinity of the large diameter portion 1b of the narrow opening portion 1a to provide means for opening the seal. These perforations 2b, 2
The length and pitch of the cut c is usually about 1.0 mm, but it varies somewhat depending on the material and thickness of the cap seal. Hold the tongue piece 2a and pull it with a relatively strong force. It is designed to be torn. When such a cap seal 2 is placed on the bottle stopper 1 from above and subjected to heat processing, it will shrink and come into close contact with the bottle body, so that it can be attached. To open the bag, raise the tongue 2a and break it upward along the perforation 2b, and also in the circumferential direction along the perforation 2c, remove the upper part from the perforation 2c, and open the stopper. I'm starting to do that.

[The problem that the idea attempts to solve]

However, if it is not possible to increase the difference in diameter between the large diameter part and the narrow mouth part of the bottle stopper due to container design, or if the cap seal is made of heat-shrinkable synthetic resin, heat shrinkage during heat-sealing may be difficult. If the heat-shrinkable synthetic resin film is not strong enough, or if the material of the heat-shrinkable synthetic resin film is soft or thin, or if the cap seal is not attached to the bottle stopper with adhesive. When the cap seal is not completely fixed, there is a problem in that the cap seal tends to come off after being attached, impairing the sealing guarantee, and there is no means to solve this problem. In addition, providing safe products is an important issue for manufacturers these days, and more reliable sealing guarantees are being pursued.

[Means to solve the problem]

This invention was devised in order to completely maintain the sealability of the cap seal when only the upper part of the bottle stopper is removed while leaving the lower part when opening. A cap seal designed to seal a bottle stopper with a diameter part and remove only the top part of the bottle stopper, leaving the bottom part, using easy-to-break parts provided in the axial and circumferential directions of the bottle, and covers the narrow mouth part. At the lower part of the seal, an easy-to-break part is formed to ensure sealing, and the easy-to-break part is discontinuous with respect to the upper part.

[Effect]

According to such a configuration, even if the cap seal attached to the bottle stopper is in a state where it is easy to come off as described above, if you try to pull the cap seal upward, the seal attached to the part covering the narrow mouth of the bottle stopper will be removed. When the perforations or grooves, which are easily broken parts, pass through the large diameter part where the opening side of the narrow mouth part of the bottle has expanded, the diameter of the cap seal in the part where the easily broken part is provided is small. , the large-diameter portion expands with a small external force, causing cracks in the easily broken perforations or grooves, making it obvious that the package has been opened.

Further, since the upper and lower easy-to-break parts are discontinuous, only the upper easy-to-break part is always broken when opening the cap seal, and the lower part of the cap seal is never removed.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 to 7.

Figures 1 and 2 are an embodiment of the present invention,
This is an example of a wine bottle with a cap seal made of heat-shrinkable synthetic resin film.

Components that are the same as those of the prior art shown in FIGS. 8 and 9 are designated by the same reference numerals, and redundant explanation thereof will be omitted.

In FIG. 1, a bottle stopper 1 of a cap seal 2 is shown.
A crack is generated in the part covering the narrow mouth part 1a of the bottle by a relatively weak external force in the axial direction of the bottle from a position at an appropriate distance from the perforation 2c in the circumferential direction and from the lower end of the cap seal 2. Perforations 3 are formed as easy-to-break parts to ensure sealing. This perforation 3 is a cut and a pitch.
It is formed to about 0.3 to 1.2 mm. If you try to pull out such a cap seal before opening it, as shown in Figure 2, the perforation 3 will be inserted into the large diameter section 1.
A crack is created by being pushed wide by b, making it obvious that a prank has been played.

Furthermore, since the upper perforations 2b, 2c and the lower perforations 3 are discontinuous, only the upper part is removed when the bag is opened, and the lower part is not removed at the same time. Therefore, the presence or absence of any mischief can be seen at a glance even after the package is opened, and the printed content always remains even after the package is opened.

Next, another embodiment of the present invention will be described based on FIGS. 3 and 4.

In FIGS. 3 and 4, an easy-to-break part for sealing guarantee is provided at the same position as above, covering the narrow opening 1a of the cap seal 2.

That is, the easy-to-break part for sealing guarantee of this embodiment is formed of perforations 4, 4 formed at predetermined intervals in the circumferential direction and perforations 5 in the axial direction that connect the perforations 4, 4. There is.

In addition, in all of the following embodiments, an easy-to-break part for sealing guarantee is provided at the same position.

FIGS. 5 and 6 show other embodiments, in which the easy-to-break parts for sealing guarantee are provided with V-shaped holes at the perforations 6 in the axial direction and at the upper and lower ends of the perforations 6, respectively.
Letter-shaped perforation 6a and inverted V-shaped perforation 6b
It is formed from.

FIG. 7 shows another embodiment, in which the easy-to-break parts for sealing guarantee are made of parallel perforations 7, 7 at appropriate intervals in the circumferential direction and X-shaped perforations connected to the perforations 7, 7. It is formed from eye 8.

In any of these embodiments, the same effect can be obtained even if the easily broken portion is formed by a groove.

It goes without saying that it is better if the bottle has a diameter difference on the outer circumferential surface of the bottle stopper to prevent the cap seal from being pulled out, and it is also better to remove only the top of the bottle stopper, leaving the bottom part intact. Cap seals designed in this way are explained using heat-shrinkable synthetic resin as an example in Figures 1 to 7, but cap seals designed for sealing purposes can be made in various forms The present invention is also applicable to objects.

The perforations or grooves, which are easily breakable parts for sealing, are not limited to the embodiments, and the selection, number, and position of the perforations or grooves may be any part covered by the narrow opening. The shape is also circumferential,
Needless to say, there may be an axial direction, an oblique direction (for example, a cross shape, etc.), or a combination of each. It is better if the number, position, and shape of these are appropriately selected and set in accordance with the material, shape, design, etc. of the cap seal.

[Effect of idea]

As is clear from the above description, according to the present invention, in a cap seal designed so that only the upper part of the bottle stopper can be removed at the easily broken part while leaving the lower part, the lower part covering the narrow mouth part has a sealing guarantee. Since the lower easy-to-break part is discontinuous with the upper easy-to-break part, even if the cap seal is in a state where it is easy to pull out, if you try to pull it out by mischief before opening the cap seal, Since the easy-to-break part for sealing guarantee is expanded by the large-diameter part and a crack is generated, it is possible to easily see from the appearance that there has been a mischief. It is possible to reliably provide seal guarantee, which is the function that cap seals originally have, and it is possible to provide safe products to consumers and maintain product value.

In addition, the easy-to-break parts at the top and bottom are discontinuous, and the top and bottom of the cap seal are not removed when the package is opened, so the bottom of the cap seal always remains after the package is opened. It also has the effect of allowing the printed contents to remain even after the package is opened.
