Description

  The present invention relates to a glass bottle with a shrink label that can be easily found to be broken when the glass bottle is broken by dropping or the like.

A glass bottle having a barrel portion covered with a shrink label has a drawback that when the barrel portion is cracked and the internal solution leaks, the leaked liquid remains inside the shrink label and is difficult to detect. In particular, small glass bottles with an internal volume of 50 to 100 ml or a bottle height of about 100 to 130 mm are often held by holding a plurality of bottles at a time in the operation of arranging them from the packaging box to the storefront. There is a high possibility of cracking.
In such a case, the bottle may be displayed despite being broken, and the consumer may not notice until after purchase.
Therefore, glass bottles with shrink labels must be able to easily find cracks. A glass bottle with a shrink label that can easily find a crack in the bottle is disclosed in, for example, the following Patent Documents 1 and 2.

  In Patent Document 1, a large number of vertical grooves are formed in the bottle body, and communication holes for communicating the vertical grooves and the outside are provided above and below the position of the vertical grooves of the shrink label that covers the body. . When bottle cracks occur and the inner solution leaks to the outer surface of the bottle body, the inner solution flows out of the shrink label from the communication hole, and the bottle cracks are easily detected.

  In Patent Document 2, many irregularities are formed in a bottle body portion to form concave portions that are continuous in the vertical and horizontal directions, the body portion is covered with a shrink label, and the upper end of the shrink label is formed in the region where the unevenness is formed. When the lower end of the shrink label is above the lower end of the region where the irregularities are formed and the bottle cracks and the inner solution leaks to the outer surface of the bottle body, the inner solution is discharged from the lower end of the shrink label. It has a configuration that flows out and makes it easy to find bottle cracks.

Japanese Patent No. 4030976 Japanese Patent No. 48275538

  The glass bottle of Patent Document 1 has a configuration in which the leaked inner solution comes out from the communication hole that communicates the vertical groove and the outside, so that the communication holes formed in the shrink label surely have all the vertical grooves. Therefore, it is necessary to perform alignment so that the shrink label is attached. If the position of the communication hole is not correct, the expected effect will not be achieved, and the shrink label must be peeled off and reattached. If the communication holes are provided at a very fine pitch, positioning is not necessary, but the portion provided with the communication holes of the shrink label becomes fragile and is cut in the distribution process, so that the appearance is extremely deteriorated.

  The glass bottle of the above-mentioned patent document 2 does not require the alignment of the shrink label, there is no fear that the shrink label is cut at the distribution stage, and the unevenness may be fine, so that the strength reduction of the glass bottle body is small.

  However, in order to attach the lower end of the label so that it is above the region where the irregularities of the bottle body are formed, it is necessary to hold the label in a state of being floated from the lower end of the bottle and to heat shrink it. It was difficult to carry out this process stably. In addition, there is a problem that the label tends to slip out upward in the bottle.

  The present invention further improves the glass bottle with the shrink label of Patent Document 2 described above, facilitates the installation of the shrink label, prevents the shrink label from slipping out, and flows out to the outside when a bottle crack occurs. An object is to make it easy to find bottle cracks by relatively increasing the amount of the inner solution.

[Claim 1]
The present invention forms a plurality of vertical grooves on the outer peripheral surface of the bottle body,
A radial knurling groove is formed from the bottom of the bottle to the bottom,
A shrink label is attached to the outer periphery of the glass bottle in which a circumferential lateral groove is formed between the knurling groove and the longitudinal groove,
The space formed between the inner surface of the shrink label and the vertical groove, the knurling groove and the horizontal groove communicates with each other.
A glass bottle with a shrink label, wherein when a crack occurs in the barrel part of the glass bottle, the internal solution leaking to the outer peripheral surface of the barrel part moves through the space and flows out from the knurling groove at the lower end of the shrink label. It is.

In the glass bottle with a shrink label of the present invention, when the bottle breaks, the inner solution flows out from the knurling groove formed from the bottom to the bottom of the bottle. There is no need to hold it in a floating state from the lower end, and it is easy to mount the label.
The lower end of the shrink label may be in a position covering a part of the knurling groove.

  Since the longitudinal groove can secure a sufficient width and depth for the inner solution to flow, the amount of the inner solution flowing out to the outside when the bottle cracking can be relatively increased, and the bottle cracking can be detected more easily.

[Claim 2]
Moreover, this invention is a glass bottle with a shrink label of Claim 1 which has the upper end of the said shrink label below the said vertical groove upper end.

  When the upper end of the shrink label is below the upper end of the vertical groove, air freely enters the vertical groove from the upper end of the shrink label, so that the inner solution smoothly falls in the vertical groove and flows to the outside at the time of cracking. This will increase the amount of water and make it easier to find bottle cracks.

[Claim 3]
Further, the present invention forms an uneven surface having a concave portion continuous at least in the vertical direction due to a large number of unevenness on the outer peripheral surface of the bottle body,
A radial knurling groove is formed from the bottom of the bottle to the bottom,
A shrink label is attached to the outer periphery of the glass bottle in which a circumferential transverse groove is formed between the knurling groove and the uneven surface,
The space formed between the inner surface of the shrink label and the recess, the knurling groove and the lateral groove communicates with each other.
A glass bottle with a shrink label, wherein when a crack occurs in the barrel part of the glass bottle, the internal solution leaking to the outer peripheral surface of the barrel part moves through the space and flows out from the knurling groove at the lower end of the shrink label. It is.

  In the present invention, an uneven surface is formed on the outer peripheral surface of the bottle body portion in place of the longitudinal groove of the invention of claim 1, and the inner solution is used when the bottle breaks, as in the invention of claim 1. Since it flows out from the knurling groove formed from the top to the bottom, it is easy to detect bottle cracks, and when attaching a shrink label, it is not necessary to hold the label in a state of being lifted from the bottom of the bottle. The bottle is wound up to the bottom and there is no worry of the label coming off.

  The uneven surface may be formed by providing grooves and a large number of small protrusions on the outer surface of the bottle, and may have various forms such as a checkered pattern or a satin pattern combined with irregular fine unevenness. The concave portion that is continuous at least in the vertical direction may be an aspect that allows the inner solution that has flowed out to the outer surface of the bottle to flow downward through the concave portion. However, it is more preferable that the concave portion is continuous in the vertical direction and the horizontal direction because the lowering of the inner solution is further promoted. The concave / convex surface in which the concave portions are continuous in the vertical direction and the horizontal direction is a lattice-like groove, a large number of small protrusions, a grid pattern, a satin pattern, and the like.

[Claim 4]
Moreover, this invention is a glass bottle with a shrink label of Claim 3 which has the upper end of the said shrink label below the said uneven | corrugated surface upper end.

  If the upper end of the shrink label is below the upper end of the concave / convex surface, air freely enters the recess from the upper end of the shrink label, so the amount of the inner solution that flows out to the outside due to the inner solution smoothly falling in the recess during cracking Increases, making it easier to find bottle cracks.

[Claim 5]
Further, the present invention provides the glass bottle with a shrink label according to any one of claims 1 to 4, wherein a finishing mold and a bottom mold parting line for forming the glass bottle are formed on a smooth surface without unevenness of the lateral groove. It is.

If the vertical groove or the uneven surface is extended to the bottom mold, the risk of occurrence of chatter (fine cracks) during molding increases. When the finishing mold is opened, when a rotational force is applied to the bottle, it is easy for chatter to enter the vertical groove or uneven surface in the bottom mold.
In addition, due to the difference in shape between the finish mold and the bottom mold during thermal expansion and the gap between the molds, it is difficult for the vertical grooves to have uneven patterns.
By forming the finishing mold and the bottom mold parting line (between the finishing mold and the bottom mold) on a smooth surface without unevenness in the lateral groove, such a problem can be prevented.

  In the glass bottle with a shrink label of the present invention, when the bottle breaks, the inner solution flows out from the knurling groove formed from the bottom to the bottom of the bottle. There is no need to hold it in a floating state from the bottom, label mounting is easy, and the label is wound up to the bottom of the bottle, so there is no worry of the label coming off.

  If the upper end of the shrink label is located below the upper end of the vertical groove or uneven surface, air can freely enter the vertical groove or recess from the upper end of the shrink label, so that the inner solution smoothly flows through the vertical groove when cracking. The amount of internal solution that falls and flows to the outside increases, making it easier to detect bottle cracks.

  In addition, by appropriately selecting the width and depth of the flutes or the shape of the uneven surface, the amount of the internal solution that flows out to the outside when a bottle cracking occurs is relatively large, so that the bottle cracking can be easily detected. Can be.

BEST MODE FOR CARRYING OUT THE INVENTION

  The glass bottle 1a of FIG. 1 is a small beverage bottle (round bottle), and has a mouth part 11, a bead 12, a neck part 13, a shoulder part 14, a trunk part 15, a skirt part 16, and a bottom part 17 from the top. The mouth portion 11 has a screw for screwing the cap. The neck portion 13 is smaller in diameter than the bead 12 and the trunk portion 15 and is a shoulder portion 14 whose diameter gradually increases from the lower end of the neck portion to the upper end of the trunk portion. The body portion 15 is a vertical so-called straight body (cylindrical shape). A skirt portion 16 whose diameter gradually decreases from the lower end of the body portion to the bottom portion 17 is formed.

The shoulder 14 and the body 15 are provided with longitudinal grooves 2 at predetermined intervals over the entire circumference. The width and depth of the longitudinal groove may be determined as appropriate. For example, the width and depth may be about 3 to 8 mm and the depth may be about 0.3 to 0.8 mm.
The longitudinal groove should just be provided in at least one part of the trunk | drum.

  A radial knurling groove 4 protruding from the knurling groove 4 is formed by forming the radial knurling groove 4 from the skirt portion 16 to the bottom portion 17. For example, the width of the knurling groove can be 1.5 to 3.0 mm, the length can be 2.0 to 7.0 mm, and the depth can be 0.2 to 0.5 mm. The knurling groove and the knurling may be slightly inclined with respect to the radial direction.

  A lateral groove 3 is formed over the entire circumference between the trunk and the skirt. 4 and 5, the basic outline of the bottle when no lateral groove is formed is indicated by a chain line α. The width of the lateral groove is preferably about 5 to 8 mm, and the depth is preferably about 0.3 to 0.5 mm.
