Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cap seal for sealing the stopper of a bottle such as a sake bottle.

[Conventional technology]

Generally, a cap seal made of a heat-shrinkable sheet is applied to bottles for wine and other liquors in order to seal the bottle stopper. As shown in Fig. 7, the cap seal has a shape that tightly seals the bottle body 1 from the neck part 2 to the bead part 3 and bottle stopper part 4, and is torn off to open the bottle when drinking. ,
A broken line notch (perforation) and a tongue piece for tearing the cut are formed as a means for easily tearing it off.

To explain the conventional cap seal based on FIGS. 7 and 8, as shown in FIG. A tongue piece part 7 is formed on the upper part of this broken line cut part 6 by a U-shaped linear cut line 8 and a pair of left and right broken line cut parts 8a, and this cut part 8a is formed in the bead part. It has almost reached the upper edge of 3. Further, a decorative seal 9 is attached to the top surface covering the bottle stopper part 4. This cap seal 5 has a diameter larger than the diameter of the bead portion 3, and as shown in FIG. A U-shaped straight line in which a broken line notch 6 is carved in the width direction of the leaf 10 and a tongue piece 7 is formed by folding the sheet 10 in half at the upper part of the broken line notch 6. It is formed by carving a shaped notch 8 and a broken line notch 8a. Next, this sheet 10 is made into a cylindrical shape and preformed by bending the upper edge inward in an annular shape from the broken line notch 6 to form a decorative seal made of a material other than a heat-shrinkable seal, if necessary. 9 is glued to the top surface to form a cylindrical body. Cap seals formed into a cylindrical body in this way are usually used for sealing after being assembled into a predetermined number by a nesting operation in which multiple paper caps are stacked one on top of the other to form a bar shape. The bottles are temporarily packed and stored until the bottles are sealed, and when sealing the bottles, they are placed in an automatic sealing device in this nested state, and the automatic sealing device feeds out the cap seals one by one and wraps the bottles one by one.
The neck part 2 of the bottle is capped from above and heat-shrinked to fit tightly onto the bottle body 1.

To open the cap seal 5, raise the tongue 7 by scratching it with your fingertips, then pinch the tongue 7 with your fingers and pull it upward along the broken line notch 8a. As the tongue piece part 7 is broken, the peripheral edge of the hole formed by pulling up the tongue part 7 and breaking it is pulled up in the circumferential direction along the circumferential broken line cut part 6. This is done by proceeding with the break and removing the upper part from the broken line notch 6.

[Problem that the invention attempts to solve]

However, according to the above-mentioned conventional cap seal, when an attempt is made to pick up the tongue portion when opening the seal, the tongue portion 7 is formed so as to be pulled upwardly from the bottom by the notches 8 and 8a, and is brought into close contact with the bottle body. As a result, it is impossible to pinch the tongue portion 7 without raising the tip of the tongue portion 7 with a toe or the like. Cap seals are made of relatively hard and thin material, so
There is a problem in that the fingertips may be injured or hurt when raising the lower end of the tongue portion 7 with the tip of the toe or the like.

In addition, if the tongue portion 7 is formed to protrude largely from the bottle so that it can be easily raised, the tongue portion 7 that protrudes greatly will create resistance during the nesting operation or when unrolling from the nesting state in the sealing process. In addition, the large protruding tongue portion 7 may catch on other cap seals and cause them to break, causing the cap seal to break.In conventional cap seals, the tongue portion 7 It was not possible to form 7 with a large protrusion.

Furthermore, in the conventional cap seal, since the broken line notch 8a forming the tongue portion and the circumferential broken line notch 6 do not intersect, the tongue portion 7 cannot be pulled upward to be broken. However, since the circumferential broken-line notch 6 does not begin to break due to the breakage, there is a problem in that it is not easy to open the package.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is made of a heat-shrinkable sheet, and has two parallel broken-line notches 6, 6 having a predetermined interval in the circumferential direction. A downwardly facing U-shaped straight cut portion 8 is formed in the axial direction near the upper broken line cut portion 6 and below the top surface of the cap seal. A tongue piece part 7 for scraping consists of two broken line notches 8a, 8a that extend downward in the axial direction from both ends of the shaped notch 8 and do not reach the lower broken line notch 6. A straight cut portion 11 having a width slightly longer than the width of the tongue portion 7 in the circumferential direction is formed in a part of the lower broken line cut portion of the tongue portion 7. The upper end of the part 7 protrudes along the outer periphery near the upper part of the bottle neck part 2, and the tongue part 7 is torn from the top to the bottom at the bottle neck part 2. It consists of a cap seal.

[Effect]

According to the present invention, a downwardly facing U-shaped straight line is formed in a part of the leaf of the cap seal above the upper broken line notch 6 and below the top surface of the cap seal. From two broken line cut parts 8a, 8a that do not reach the lower broken line cut part 6 extending downward in the axial direction from both ends of the cut part 8 and the U-shaped linear cut part 8. Since the tongue piece part 7 is formed, the tongue piece part can be easily formed, and since there is no redundant or unnecessary part in the single leaf of the cap seal, the single leaf of the cap seal can be easily formed. It is also economical and saves money.

The tongue portion 7 is formed to protrude upwardly along the outer periphery near the top of the bottle neck, and in the nesting state, the tongue piece 7 is formed to protrude upward along the outer periphery near the top of the bottle neck of the cap seal, which has a cylindrical shape as shown in FIG. Since it is slightly peeled upward along the outer periphery and opened toward the upper part of the neck of the bottle, there is no risk of the tongue part getting caught and causing trouble. Furthermore, after heat shrinking, the shape is greatly protruded from the outer periphery near the top of the bottle, so there is no need to raise the tongue portion, so there is no risk of injury or pain to the fingertips.

Also, pinch the tongue portion 7 with your fingertips, etc., and cut the broken line cut portion 8.
When it breaks from the top to the bottom along the line a, the break reaches the linear notch 11 and the tongue portion 7 separates. At this time, the linear cut portion 11 is inserted into the tongue portion 7.
Because it has a width slightly longer than the circumferential width of
Even if the breakage of the tongue portion 7 is shifted laterally from the broken line cut portion 8a, the tongue portion 7 can be reliably separated. From the separated hole of the tongue portion 7, along the two parallel broken line notches 6, 6 having a predetermined interval in the circumferential direction, the broken line notches 6, 6 are made in the circumferential direction. When the bag is torn into strips between the openings, the upper portion is removed from the lower broken-line cut portion 6, making it possible to open the bag. These two circumferential broken line cut portions 6, 6 begin to break slightly as the tongue portion 7 breaks. Alternatively, the periphery of the hole after the tongue portion 7 is separated is in a raised state, and the linear cut portion 11 has a width slightly longer than the width of the tongue portion 7 in the circumferential direction. , easy to initiate rupture. Further, the cap seal can be removed by only a weak force that causes the band to break between the two broken line notches 6, 6, and the cap seal can also be removed cleanly.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

Figures 1 and 2 are a partial perspective view and a plan view of a sheet of paper showing the first embodiment, and Figures 3 and 4 are
FIGS. 5A and 5B are plan views showing other embodiments of the single sheet, and FIG. 6 is a longitudinal sectional side view of the cap seal. Since the same reference numerals as in FIG. 8 and FIG. 8 are the same constituent parts, redundant explanation will be omitted.

In the first embodiment, the broken line notches 6 are carved in two identical and parallel circumferential steps along the upper and lower edges of the bead portion 3, and the lower broken line notches 6 are provided with: A slightly longer linear cut portion 11 is formed to the extent that at least two perforations are continuous, and the tongue piece portion 7
It is formed by a pair of left and right broken line notches 8a on the upper part of the slightly longer linear cut part 11 and a U-shaped linear cut part 8 formed on the upper part thereof. It protrudes upward without being continuous with 6. As shown in FIG. 2, there are two broken line cut portions 6, 6 having a constant interval in the width direction of the sheet 10, and a linear cut portion 1 in a part of the lower broken line cut portion.
1 is engraved, and a linear cut portion in the shape of a “shaped portion” that does not intersect with the two broken line cut portions 6, 6 and forms a half of the tongue piece portion 7 near one folded portion of the sheet 10. 8 and a broken line cut part 8a that ends between the upper and lower broken line cut parts 6, 6.Therefore, when this sheet 10 is made into a cylindrical body, a straight cut part 8a is formed. The line 8 has a U-shape, the broken line cut portions 8a are integrated on the left and right sides, the tongue portion 7 is formed, and the linear cut portion 11 and the starting end 6a of the broken line cut portion 6 are twice as long. A cutting line is formed, and a broken line cut portion 6,
6 is formed in a circumferential shape. Note that the broken line notch 6
The starting end 6a of the cap seal 5 is formed so that the back side of the tongue portion 7 of the cap seal 5 can be reliably broken.

The second embodiment is substantially the same as the first embodiment,
The difference is that the distance between the pair of broken line notches 6, 6 has been made smaller, that is, the broken line notches 6, 6 have moved inward slightly away from the upper and lower edges of the bead part 3. It lies in being. That is, since the width between the broken line notches 6 and 6 is narrow and is on the same curved surface as the bead part 3, it is easy to scrape the gap between the broken line notches 6 and 6 into a band shape. On the contrary, the first
In the embodiment shown in FIG.
Since it is along the upper and lower edges of the bead portion 3 and is not on the same curved surface as the bead portion 3, the scratching function is slightly inferior compared to the second embodiment, but it has the advantage of having a good appearance.

In addition, FIGS. 5A and 5B show other embodiments of single wafers, and in the example of FIG. 5A, the broken line cut 8a is extended to the position where it contacts the lower broken line cut 6 In addition, the pitches 6a at the starting ends of the broken line notches 6 and 6 and the other starting ends 6b and 6c near the tongue portions are made larger than the other pitches, and the lower pitch 6c is made upward. Pitzchi 6b
It is formed larger than the As a result, it is easy to scrape the area between the broken line notches 6, 6 in a band-like manner, and the cap seal on the back side of the tongue portion 7 can be reliably broken. In the example shown in FIG. 5B, instead of the broken line cut part 8a, a straight cut part 8b, which has a shape in which the parentheses are opened outward, is formed so as not to intersect with the broken line cut parts 6, 6. The space between the broken line notches 6 and 6 is designed to be easily scraped in a band shape.

Therefore, as shown in FIG. 6, in any of the above embodiments, after heat shrinkage, the tongue portion 7 has a drawn shape protruding toward the bottle stopper portion 4 side, and before heat shrinkage, the tongue portion 7 has a drawn shape. The cap seal peels off slightly upward along the outer periphery near the top of the bottle and opens upwards toward the neck of the bottle, so it does not interfere with or resist other objects even when nested. . In addition, a circumferential broken-line cut portion 6 having a linear cut portion 11 is formed in the direction in which the tongue portion 7 is broken.

[Effect of idea]

According to the present invention described above, since the upper end of the tongue protrudes upward along the outer periphery near the upper part of the bottle neck, there is no need to lift the tongue and the tongue can be easily pinched with the fingertips. , will not injure or hurt your fingertips. Moreover, before the tongue piece 7 is heat-shrinked, it peels off slightly upward along the outer periphery of the cap seal near the top of the bottle, and is in an open state toward the top of the bottle neck, so that it can be easily used during nesting work. There is no risk of any hindrance. Also, the tongue piece part 7
If you pick it up with your fingertips and break it from the top to the bottom along the broken line notch 8a, you can reliably separate the tongue part. This has effects such as being able to easily initiate rupture.

Further, since the tongue piece 7 is formed in a part of the cap seal, there is an effect that the cap seal sheets can be used economically without wasting them.
