Description

[Detailed description of the invention] [Industrial application field] This invention is a heat-shrinkable label that is applied to the outer surface of containers such as liquid beverage containers for the purpose of displaying contents, decoration, product differentiation, etc. and a container covered with this heat-shrinkable label.

[Prior Art] A heat-shrinkable label is applied to the outer surface of a container as a means of increasing the added value of a product and differentiating it from similar products. For example, thickness 50~
Plastic beverage containers made of 60μ polyvinyl chloride resin, 40-50μ polystyrene resin, polyethylene terephthalate resin, etc. and covered with a heat-shrinkable film with a beautiful and easily noticeable design printed in multiple colors are now on the market. It's on.

To explain further based on specific examples, it is a plastic container filled with fruit drinks such as orange juice and grapefruit, neutral drinks such as sports drinks, soft drinks such as oolong tea, coffee, black tea, and mineral water. It is made of a plastic polymer such as polyethylene terephthalate (PET), and has a structure that extends from the opening where the cap is attached, through the support ring, shoulders, and body to the bottom. Transparent, heat-set plastic bottles with stretch-oriented crystals are often used, and the heat-shrinkable labels are used with the intention of increasing added value and differentiating products.

The filling temperature of the beverage is 70 to 95°C, and it is commonly called a hot pack product. After filling the contents, it is screwed with a cap that has been sterilized with ultraviolet rays or ethylene oxide, and then screwed again with the cap. After that, turn the container on its side to sterilize the cap, then return it to an upright position, pass it through the pasteurizer, sterilize the entire bottle in a hot shower at around 74℃ for about 15 minutes, and then shower it with room temperature water for about 5 minutes. A very common process is the filling and sterilization process.

Because it is for high-temperature filling, negative pressure is applied when the content cools, which tends to cause deformation such as warping and denting of the bolt, and also prevents deformation due to the heat history of hot showers and cool showers used as a sterilization method. Furthermore, in order to withstand external forces from the vertical direction, it was necessary to reinforce the body, so a beam extending in the vertical direction of the bottle was installed, and multiple sets of recessed panels were installed between the beams. It is designed so that it will not be noticeable even if it is deformed.

Figure 4 shows an example of such a plastic bottle, where 1 is the mouth, 2 is the support ring, 3 is the shoulder, 4 is the body, 5 is the bottom, and 6 is the reinforcement formed on the body. The reference beam 7 indicates a recessed panel section provided between the beams.

[Problems to be Solved by the Invention] By the way, when heat-shrinkable labels are applied to such plastic bottles, they are usually applied not to the body of the bottle but to the upper shoulder.

The reasons for this are as follows.

When passing through the pasteurizer, the bottle is subjected to hot shower and cool shower, but at this time,
Hot shower and cool shower enters through the small gap between the heat-shrinkable label on the body and the outside of the bottle, collects as water in the recessed panel on the body, runs down during transportation and storage, and wets the outer cardboard. There was a problem with damage. Another problem is that if water accumulated in the recessed panels is left for a long time, it will rot and become unsanitary, causing discomfort to consumers and leading to a decline in sales.

Water droplets attached to the back side of the label are visible from the front side and spoil the appearance of the product.

After the label is attached to the body of the bottle, it is passed through a circulating hot air tunnel, but hot air accumulates in the recessed panel provided on the body, making the label easy to loosen, warp, wrinkle, etc., and lack beauty. , the defective rate of labels or containers is high.

If the width of the beam provided in the body, the shape, width, depth, etc. of the recessed panel are not designed appropriately, the bottle itself will deform when negative pressure is generated during high-temperature filling, causing distortion and loosening of the label.

For the reasons mentioned above, heat-shrinkable labels were applied to the shoulders, but from the standpoint of increasing the added value of the product and differentiating it from other products, it is important to attach the label as much as possible. It is desired that the label be attached to the body, which can take up a large area and give a good finish to the label.

Therefore, the purpose of this invention is to create a heat-shrinkable label that can be attached to a container that has a concave portion on its outer surface. It is an object of the present invention to provide a label that does not cause sagging, and also to provide a container having a high commercial value to which such a label is attached.

[Means for Solving the Problems] In order to achieve the above object, the heat-shrinkable label according to this invention is characterized in that small holes are formed for water and air drainage.

That is, in a heat-shrinkable label made of polyvinyl chloride resin, polystyrene resin, polyethylene terephthalate resin, etc., and attached to the outer surface of a container, a plurality of small holes are formed at the lower edge position of a recess formed on the outer surface of the container. This method was adopted.

Moreover, the container according to this invention is a container covered with such a heat-shrinkable label, and the outer surface having the recessed portion is covered with a heat-shrinkable label made of polyvinyl chloride resin, polystyrene resin, polyethylene terephthalate resin, etc. In the container, the heat-shrinkable label has a plurality of small holes formed at the lower edge of the recess on the outer surface of the container.

[Function] Even when this kind of heat-shrinkable label is attached to the outer surface of a container that has a recessed part, the small holes function to drain water and air, so water and air do not accumulate on the back of the label, and the above-mentioned problem occurs. Even when it is applied to the body of a hot-filled bottle, the disadvantages seen in the prior art do not occur. Since the label area can be increased, various indications and decorations can be applied.

In addition, a container with such a label can be made into a container with high commercial value by effectively utilizing the high added value and differentiation effect of the label.

[Example] Hereinafter, the example shown in FIGS. 1 to 3, which is applied to a high-temperature filling bottle, will be described.

In the drawings, the structure of the bottle is the same as the conventional bottle, and the same parts are designated by the same reference numerals. That is, 1 is a mouth part, 2 is a support ring, 3 is a shoulder part, 4 is a body part, 5 is a bottom part, 6 is a reinforcing beam formed in the body part, and 7 is a concave panel part provided between the beams. It is. 8 is a heat-shrinkable label that is attached to the entire body part 4 (from part A to B) and also to the bottom part 5, and has a beautiful and easily noticeable design printed in multiple colors. . Reference numeral 9 denotes a plurality of small holes formed in the label 8 at the lower edge position of the recess of the recessed panel portion 7, which are not particularly noticeable and are formed at such a size and interval that they do not cause damage to the label. . As shown in FIG. 2, the beams are stretched with appropriate tension.

In addition, although the above-mentioned example shows an example of application to a hot-filled bottle, in short, a similar problem is expected in a container having a concave portion on the outer surface, so application to these containers is not excluded.

[Effects of the invention] The heat-shrinkable label of this invention is as described above, and even when the container has a recess on the outer surface, the label can be attached to cover the upper surface of the recess.
There are no water droplets or air remaining on the back of the label, which eliminates the problems caused by this, and the label area can be greatly expanded, making it possible to create a label that can be used for effective display and decoration. be.

Therefore, containers with such labels are
Compared to the one where the recess was removed and the label was attached,
It has the advantage of dramatically increasing product value.
