Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attached to a plastic bottle and a plastic bottle using this label.

[0002]

2. Description of the Related Art Generally, a plastic bottle such as a PET bottle is provided with various kinds of labels in order to protect the container from damage, display contents, and design. If the label is difficult to remove, it will hinder the recycling of the container after use. Therefore, it is desirable that the label can be easily removed from the container.

An example of such a label is Japanese Patent Laid-Open No.
No. 01-42775 discloses a label laminated with a specific adhesive.

[0004]

However, in many cases, the plastic bottle 1 is provided with a groove 2 for reinforcing the strength of the bottle, as shown in FIG. 1 (a).
When a label is attached so as to cover the groove 2, the groove 2
In many cases, adhesive gets inside.

When the adhesive enters the groove, this adhesive does not contribute to the sticking of the plastic bottle and the label and is wasted. Further, the adhesive in the groove is dried due to contact with air, solids are deposited and whitening occurs, and adhesive residue is left on the plastic bottle, which hinders the recycling of the plastic bottle and is not preferable in appearance.

Therefore, an object of the present invention is to provide a plastic bottle sticking label which is preferable for recycling plastic bottles and has a good appearance, and a plastic bottle to which this label is stuck.

[0007]

According to the present invention, in a label having an adhesive layer attached to a plastic bottle having a groove on its surface, the label is arranged on a flat surface portion of the plastic bottle in which the groove is not provided. The above problem was solved by using a label attached to a plastic bottle in which an adhesive layer is provided only on the above label portion.

Since the adhesive layer is provided only at the predetermined position of the label, it is possible to prevent the adhesive from entering the groove provided in the plastic bottle, that is, the adhesive residue. This reduces the amount of adhesive that comes into contact with air, prevents whitening, and prevents adhesive residue from forming on the plastic bottle, which is preferable for recycling plastic bottles and also for appearance.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. The label 3 attached to a plastic bottle according to the present invention is a label attached to a plastic bottle 1 having a groove 2 on the surface as shown in FIG. 1 (a). The label 3 has an adhesive layer on one surface of the label body. As shown in FIG. 1 (b), the label 3 having the adhesive layer is wound around the plastic bottle 1 so that the adhesive layer faces the plastic bottle 1, and the plastic bottle 1 is wrapped around the plastic bottle 1 so that the label 3 A label-attached plastic bottle is obtained by stacking and adhering the edges together.

The plastic bottle 1 is a bottle for storing beverages such as drinking water, and examples thereof include PET bottles.

The material constituting the label main body of the label 3 is preferably a material having high printing performance from the viewpoint of display of contents and design, and examples thereof include various kinds of biaxially oriented polypropylene film, non-oriented polypropylene film and the like. Examples thereof include olefin film and polyethylene terephthalate film.

As the adhesive forming the adhesive layer provided on the label 3, the plastic bottle 1 of the label 3 is used.
It is not particularly limited as long as it can be attached to a label, and the edges of the label 3 can be adhered to each other.
Any adhesive such as a hot melt adhesive or a tacking agent can be used.

As a method of arranging the above-mentioned adhesive layer, FIG.
As shown in (a) and (b), there is a method of disposing the adhesive layer 4 only on a certain part. Specifically, FIG. 1 (a)
In the case of the plastic bottle 1 having several grooves 2 provided in the circumferential direction as shown in FIG. 2, the plastic bottle 1 is arranged on a flat surface portion where the groove 2 is not provided, as shown in FIG. The adhesive layer 4a is provided only on the portion of the label 3 that is provided, and the adhesive layer 4a is not provided on the portion of the label 3 that is arranged at the position of the groove 2, and a plurality of adhesive layers 4a are provided in the length direction of the label 3.
The one with a belt is given. Further, as shown in FIG. 2B, if the adhesive layer 4a is provided in a strip shape, and if the amount of the adhesive is too large, the adhesive layer 4b is provided at several places where the adhesive layer 4a is provided. You may set up an island. The adhesive layer 5 provided on one edge of the label 3 is used to bond the edges of the label 3 when the label 3 is wrapped around the plastic bottle 1.

The method of providing the adhesive layer 4 on the label body is not particularly limited, but a method of forming by pattern printing such as gravure printing is preferable. When this pattern printing is adopted, even if the shape of the groove 2 provided in the plastic bottle 1 is changed finely, if the pattern is first confirmed, the label 3 having a large amount of the same adhesive layer 4 pattern can be easily formed. Can be obtained.

[0015]

In the label attached to the plastic bottle according to the present invention, since the adhesive layer is provided only at the predetermined position of the label, the adhesive does not enter the groove provided in the plastic bottle, that is, the adhesive residue is not generated. It can be prevented.
This reduces the amount of adhesive that comes into contact with air, prevents whitening, and prevents adhesive residue from forming on the plastic bottle, which is preferable for recycling plastic bottles and also for appearance.

When an adhesive layer is provided on the label body by pattern printing, a label having the same adhesive layer can be easily manufactured in large quantities.
