[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, a stretch label and a strip for a PET bottle which is mounted on a polyethylene terephthalate bottle filled with a carbonated beverage containing fruit juice .
It relates to a PET bottle with a tretch label .

[0002]

2. Description of the Related Art Conventionally, for example, a bottle made of polyethylene terephthalate (hereinafter referred to as
It is called a PET bottle. ) Is present in the PET bottle,
A label made of water-resistant paper on which characters or patterns were printed was attached. However, since the water-resistant paper label is attached to a PET bottle via an adhesive, it is difficult to separate the label from the bottle when the bottle is reused.

Therefore, it is general that a stretch label formed in a tubular shape is externally fitted and attached by adhering ends of a polyethylene film having self-stretchability. Then, when the above-mentioned carbonated beverage is filled in the PET bottle having the above-mentioned structure, the PET bottle is slightly expanded in the radial direction by carbonic acid, and in this state, the label P is attached.
The ET bottle 1 is sterilized (pasteurized) by spraying hot water of about 70 ° C for a predetermined time with a pasteurizer.

[0004]

However, since the sterilization treatment is performed with warm water as described above, the self-elastic contraction force of the label in a tensioned state is slightly reduced. Therefore,
When pouring drinking water from a PET bottle, carbonic acid in the bottle is released and the PET bottle shrinks in the radial direction. However, the shrinkage of the PET bottle causes the label to lose its self-elastic shrinkage force. Adhesion to the PET bottle 1 is inferior. As a result, P
When the ET bottle was lifted, the label became slippery from the PET bottle and could easily come off.

[0005] Incidentally, as means for solving the above problems, the <br/> it is conceivable to attach the stretch label to a PET bottle with an adhesive, in this case, as in the waterproof paper made labels There is a drawback that it is difficult to reuse the bottle.

The present invention has been made in view of the above-mentioned conventional problems, and by mounting the PET bottle on which the contents are heat-treated, it is difficult to slip even if the self-elastic contraction force is lowered. And prevent it from coming off from the PET bottle, and moreover, it is suitable for reuse of the PET bottle.
An object is to provide a stretch label for ET bottles and a PET bottle with stretch labels.

[0007]

The present invention has been made as a stretch label for PET bottles and a PET bottle with a stretch label in order to solve the above-mentioned problems. The feature of the stretch label for PET bottles is polyethylene. A printing layer having self-stretchability and an inner surface for external fitting to the body portion 2 of the terephthalate bottle 1
A stretch label for a PET bottle, which is formed into a tubular shape by joining end portions 9a and 9b of a polyethylene-based resin stretch film 9 provided with 11, wherein the stretch film 9 is polyethylene terephthalate. When attached to the body 2 of the bottle 1
The non-printed portion 13 is formed on the inner end 9a of the stretch film 9 that comes into contact with the bottle 1 in a direction corresponding to the height direction of the bottle 1 .

[0009]

In the stretch label for a PET bottle of the present invention, even if the self-elastic contraction force of the label 5 is weakened, the stretch film made of a polyethylene material having a relatively large friction resistance against the PET bottle 1 and being hard to slip. Since the inner end portion 9a of 9 directly contacts the body portion 2 of the PET bottle 1, even if the PET bottle 1 is lifted via the label 5, the label 5 does not slip or fall out.

Further, when the label 5 is attached to the PET bottle 1, the printing layer 11 provided inside the stretch film 9 comes into contact with the PET bottle 1 to reduce the friction resistance, so that the label 5 is attached to the PET bottle 1. It is possible to easily pull it down with respect to 1, and the mounting work can be done smoothly.

Moreover, since the non-printed portion 13 is formed at the inner end 9a of the stretch film 9 that contacts the PET bottle 1 and in the direction corresponding to the height direction of the bottle 1 , the stretch film 9 is not formed. The outer end portion 9b presses the inner end portion 9a, so that the contact pressure of the non-printed portion 13 increases, and thus the friction resistance of the label 5 also increases.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes a PET bottle filled with a carbonated beverage containing fruit juice, for example, a cylindrical label 5 is externally fitted and attached to a body portion 2 having a circular cross section, and a mouth portion at an upper portion. A cap 7 is detachably screwed to the cap 6.

The label 5 comprises a rectangular stretch film 9 having elastic elasticity made of polyethylene resin such as low density polyethylene or ethylene-vinyl acetate copolymer. ), The stretch film 9 is formed into a tubular shape by polymerizing and adhering the inner end 9a on one side and the outer end 9b on the other side.

On the inner surface of the stretch film 9, there is provided a printing layer 11 for displaying a character pattern or the like with printing ink. That is, the printed layer 11 includes a non-printed portion 13 on the inner end 9a side of the stretch film 9 and an outer end 9b.
It is provided over the entire surface of the other portion except the adhesive application portion 14 on the side, and the back surface of the outer end portion 9b is polymerized and adhered to the front surface side of the inner end portion 9a. The overlap margin L between the inner end 9a and the outer end 9b of the stretch film 9 is 1
The width L1 of the non-printing portion 13 is preferably about 1 to 10 mm, particularly about 2 to 6 mm, and the non-printing portion 13 is the height of the bottle 1.
It will be formed in a direction corresponding to the direction . Further, the outer end portion 9b and the inner end portion 9a can be adhered to each other by an appropriately known means such as heat sealing in addition to the adhesive.

The outer diameter of the label 5 is set to be slightly smaller than the outer diameter of the body portion 2 of the PET bottle 1. When the label 5 is attached to the bottle 1, the tubular stretch film 1 is tensioned. While fitting the bottle 3, the bottle 3 is fitted. Since the label 5 contains a polyethylene-based resin material, the friction resistance with respect to the PET bottle 1 is increased. However, the printed layer 11 is provided inside the stretch film 9, and the printed layer 11 and the PET bottle 1 are combined with each other. Since it reduces frictional resistance,
The label 5 can be pulled down to a predetermined position with a comparatively small force.

Further, when the label 5 is attached to the PET bottle 1, the label 5 is attached to the body portion 2 of the bottle 1 in a close contact state by its self-elastic contraction force. At this time, the unprinted portion of the inner end 9a of the stretch film 9 comes into direct contact with the body 2 of the PET bottle 1, and the outer end 9b located on the surface of the end 9a is stretch film. The elastic contraction force of 9 effectively presses the inner end 9a toward the PET bottle 1 side.

Next, after filling the PET bottle 1 having the above-mentioned structure with a carbonated beverage containing fruit juice, a sterilizing treatment such as spouting hot water of about 70 ° C. for about 10 minutes to the PET bottle 1 having the label 5 attached thereto Give. Due to the heating during the sterilization, the PET bottle 1 and the non-printed portion 13 of the stretch film 9 have a good contact state, and the friction resistance increases.

Furthermore, when the PET bottle 1 is opened and poured with the drinking water sterilized as described above, the PET bottle 1 tends to shrink slightly in the radial direction due to the release of carbonic acid. what if,
When the self-elastic contraction force of the label 5 is weakened by the warm water sterilization treatment, the inner edge 9a of the stretch film 9 having a large frictional resistance is reduced although the adhesion of the label 5 to the PET bottle 1 is reduced. Unprinted part 13
Is directly in contact with the PET bottle 1, so that even if the PET bottle 1 is lifted while holding the label 5, the label 5 is unlikely to slip on the PET bottle 1 and will not slip or slip out.

Moreover, in the above embodiment, the unprinted portion 13 of the inner end portion 9a of the stretch film 9 is not printed, but the outer end portion 9b that covers the inner end portion 9a is printed. Since the outer end 9b is covered, the printed state of the display and design is not impaired, and the appearance is hardly deteriorated.

The present invention is not limited to the above-mentioned embodiment. For example, the adhesive application portion 14 is provided on the outer end 9b of the stretch film 9 as in the above-mentioned embodiment.
As shown in (a), the printed layer 11 at the outer end 9b and the non-printed portion 13 at the inner end 9a may be polymerized via an adhesive.

In the above embodiment, the label 5 is formed by forming one stretch film 9 into a tubular shape. However, as shown in FIG. It is also possible to configure.

Further, the label 5 is most effective when the content is a carbonated beverage containing fruit juice and is subjected to heat treatment, but the content is not particularly limited, and the heat treatment may be performed without fruit juice. May be In this case, even if the label 5 is heated by sunlight or the like and the self-elastic contraction property is deteriorated, it is possible to prevent the label 5 from being displaced.

Moreover, the shape of the container 3 is not limited to the one having a circular cross section as illustrated in the above embodiment, but may be a rectangular shape or a polygonal shape, and it goes without saying that it can be arbitrarily set.

[0024]

[Effects of the Invention] The present invention uses the stretch film described above.
When mounted on the barrel of a polyethylene terephthalate bottle
The inner edge of the stretch film that contacts the body
Is the direction in which the unprinted part corresponds to the height direction of the bottle.
Because it is formed in the outer end portion will be pressed inner end to the body portion having a non-printing portion, as a result, P
By effectively utilizing the frictional resistance between the ET bottle and the polyethylene resin film, the frictional resistance of the label can be increased, and even if the self-elastic contraction force of the label becomes weak, the label will slip or fall out. There is no danger of

Therefore, for example, when the content is a carbonated beverage containing fruit juice and subjected to warm water sterilization treatment, even if the self-elastic contraction force of the label may decrease, the label should be opened to pour the drinking water. , When the PET bottle whose diameter has shrunk due to the release of carbonic acid is lifted, the label may slip or come off.
It is very practical because it has the advantage that it can be effectively prevented.

Moreover, since the label is made of a stretch film, it can be easily peeled off from the PET bottle as compared with the case where the label is made of a paper material and an adhesive is used as in the conventional case, and the PET bottle can be reused. It is also optimal in terms of.
