Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique in which a label is set in a mold in advance and the label and the bottle are integrated at the same time as blow molding, and in particular, the label itself has a handle function. It is a thing.

[0002]

2. Description of the Related Art Recently, various beverages, edible oils, liquid detergents,
Plastic bottles are widely used as containers for liquids such as automobile antifreeze. Since these large plastic bottles are inconvenient to handle, those with a handle are mainly used. As a method of providing a handle, there are a type in which a handle portion integrated with the bottle main body is formed at the time of blow molding of the bottle, a type in which a separate molded handle is adhered to the body portion of the bottle main body by using an adhesive, and the like. In the sense of reducing the amount of resin material used, the handle is not made into a molded product, but a handle member is made of a paper tube, and the bottle with the handle is attached to the bottle body. ) Is disclosed. This is effective in terms of pollution control because the handle is made of a paper tube with low calories, and it is also convenient in transportation because it is assembled and used. There is.

[0003]

However, this handle member
Since 81 is bonded after molding the bottle, it is necessary to position it when bonding, and since it is in close contact with the body of the bottle, even if there is a notch 82 for finger hooking It still has the problem of being difficult to apply. Especially in the step of applying an adhesive or a release varnish to the handle member 81,
In the case where the parting line 83 and the finger-hanging notch 82 were applied in excess, it was extremely difficult to hang the finger because there was no other trigger because the surface was flat. Also, even if you say to reduce the amount of resin material used in bottles,
There is a limit to the amount of reduction because it is necessary to secure the strength required for a bottle. Therefore, in the present invention, in the plastic bottle with a handle label, the strength of the entire bottle does not decrease even if the amount of plastic resin in the bottle body is reduced, and it is convenient during transportation and the grip portion of the handle label during use. The challenge is to be able to easily cause.

[0004]

In order to solve the above-mentioned problems, the present invention is obtained by holding a handle label on the inner surface of a cavity of a mold in advance and integrating it with a handle label simultaneously with blow molding of a bottle body. In a bottle with a handle label, the handle label has a grip part having two notches in the vertical direction and a rising part having a ┗┛-shaped notch below the grip part, and Provided is a bottle with a handle label, which is obtained by applying a release varnish on the bottle facing surface of the grip portion and the rising portion.

Further, a mold having a height difference as compared with other portions is opened in a portion of the inner surface of the cavity for holding the grip portion of the handle label, and the inner surface of the cavity is vertically extended by 2
A handle with a book cut and a rising part with a ┗┛-shaped cut below the grip, and a handle with a release varnish applied to the bottle facing surface of the grip and the rising part. Provided is a method of manufacturing a bottle with a handle label, which holds a label, then holds a parison in a mold, closes the mold, blows pressurized fluid into the parison to blow mold and integrate with the handle label.

[0006]

According to the present invention, when the handle label is held on the inner surface of the cavity of the mold and then blow molding is performed, a bottle integrated with the handle label is molded. And on the inner surface of this cavity, in the part that holds the grip part of the handle label,
Since there is a difference in height compared to other parts, if the part that holds the grip part of the handle label projects more than other parts, the bottle body will only be inside this part by the projected amount. Molded into a concave shape. In this case, since the handle label was also sandwiched between the mold and the bottle body at the time of molding, it was temporarily recessed inward and completely separated from the adhesive portion of the label by the notch. Since the peeling varnish was applied in advance to the surfaces of the grip portion and the rising portion that face the bottle body, they are not adhered to the bottle body and float up. Since the bottle body is recessed, there is already a gap between the bottle body and the handle label, but if the grip is subsequently raised, the rising portion is also raised and a sufficient gap is created. You can put your hand in.

Further, when the portion of the handle label for holding the grip portion is recessed more than the other portions, the bottle body is formed in such a shape that only this portion protrudes outward by the recessed portion. In this case, the handle label also protrudes outward along the protruding shape of the bottle body and is completely separated from the adhesive portion of the label by the notch. Since the peeling varnish was applied in advance to the surfaces of the grip portion and the rising portion that face the bottle body, they are not adhered to the bottle body and float up. When the grip portion is subsequently raised, the rising portion is also raised, so that even if the bottle body is protruding, a sufficient gap is created between the bottle body and the handle label, and the hand can be inserted here.

Therefore, in any case, even if the cutout is exceeded and the adhesive or the like is applied, the gripping portion and the rising portion are completely separated from the adhesive portion of the label by the pressure during molding. Then, a gap is created between the handle label and the bottle body, which makes it easy to put a finger.

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 4 show the first embodiment, and FIGS.
FIG. 8 is a diagram showing a second embodiment. The labels in FIG. 3 are common to the first and second embodiments.

<First Embodiment> Since the bottle body can have a single-layer or multi-layer structure, it is also possible to use a functional resin as an intermediate layer in a multi-layer structure. As the resin material, for example, a medium-low density polyethylene, polypropylene, polyethylene terephthalate, a thermoplastic resin such as polyvinyl chloride ethylene-vinyl acetate copolymer can be arbitrarily used, high strength in this embodiment, and Polyethylene terephthalate having excellent gas barrier properties was used.

As the handle label, paper, biaxially oriented polypropylene film, biaxially oriented high density polyethylene film, polyester film or the like can be optionally used. If necessary, ethylene-vinyl acetate copolymer or ethylene-vinyl acetate can be used. It can be brought into close contact with the bottle body with an adhesive interposed. In this embodiment, in consideration of the purpose of reducing the amount of plastic resin used, the thickness is 0.3 mm.
The above paper was used as a base material and an adhesive (ethylene-vinyl acetate) and a peeling varnish were applied to the back surface (the surface facing the bottle).

As shown in FIG. 3, the handle label 30 has a quadrangular shape as a whole, and is divided into two vertical cuts 32 at substantially the center, and gradually expands toward the center. The grip portion 31 is provided, and the rising portion 34 divided by the ┗┛-shaped notch 33 is provided below the grip portion 31. A fold line L1 is provided at the upper end of the grip 31 and a fold line L6 is provided at the lower end. Cut 32 again
Lines L2 and L3 are provided on the extension of the straight parts above and below,
A fold line L4 connecting the upper ends of the fold line L2 and the fold line L3 is provided, and the rising portion 34 is provided with a fold line L5 extending inward from each upper end of the notch 33 to the notch 32. Therefore, after the grip portion 31 and the rising portion 34 are raised, each fold line is bent, and the shape as a handle can be maintained, which is convenient. A peeling varnish is applied to the grip portion 31 and the rising portion 34, while the adhesive portion 35 (see FIG.
Adhesive is applied to the shaded area).

In FIG. 4, 41 is one of the left and right split molds of the blow mold. There is a portion 42 for holding the handle label 30 on the inner surface of the cavity of the split mold 41.
The portion 43 (see FIG. 4A) that holds the grip portion 31 of the (the label may be held by sucking using a suction device by providing a suction hole in this recess 43) and the other portion 44 (Fig. 4
(See (b)).

Next, the molding process of this embodiment will be described. Since polyethylene terephthalate was used in this example, it was manufactured by the injection blow molding method.
That is, first, polyethylene terephthalate was injected from the injection nozzle into the cavity of the closed mold at a resin temperature of about 230 ° C., and after cooling and solidification, the mold was opened to prepare a test tubular molded product (preform 45). . Subsequently, the preform 45 was biaxially stretch blow molded using the blow mold. That is, after opening the left and right split molds 41, the handle label 30 is transferred from a label supply device (not shown),
It is held on the inner surface of the cavity, and then stretched (about 160 ° C.).
Insert the preform 45 heated to ℃ ~ 170 ℃) into the predetermined position, and then close the left and right split molds 41,
45 was biaxially stretched with a stretching rod, compressed air was blown, and the expanded preform 45 was pressed against the handle label 30 to bring them into close contact with each other. After that, cooling air was blown from the air passage in the drawing rod to cool and solidify the bottle, and a bottle 10 with a handle label integrated with the handle label 30 was formed.

In this embodiment, the portion 43 for holding the grip portion of the handle label is the other portion 44 of the inner surface of the cavity of the mold.
Since it protrudes more than this, the bottle body portion facing this portion was formed in a shape recessed inward. Since the handle label 30 was also sandwiched between the mold and the bottle body at the time of molding, it was temporarily recessed inward and completely separated from the adhesive portion 35 of the label by the notches 32 and 33. And the grip 31
Since the peeling varnish was previously applied to the bottle body facing surface 46 of the rising portion 34, it was not adhered to the bottle body 47 and floated up. Then, when the grip 31 was raised, the rising portion 34 was also raised, and a further sufficient gap was created.

A bottle with a handle label created in this way
No. 10 had an inner volume of 2000 ml, a body thickness of 0.2 mm, and a handle label thickness of 0.3 mm. When 50 bottles with a handle label were observed, the grip portion 31 and the rising portion 34 of the handle were completely separated from the adhesive portion 35 and lifted up from the bottle body portion 47, so that it was extremely easy to grip. Put your finger on the notch 32 forming the part 31,
The grip portion 31 and the rising portion 34 could be caused. Then, add 2 bottles of liquid detergent to the bottle 10 with this handle label.
When 000 ml was filled and repeatedly poured out, the handle label 30 was not peeled off and good results were obtained.

The molding method is not limited to this, and a general extrusion blow molding method can be selected depending on the material used.

<Second Embodiment> As in the first embodiment, polyethylene terephthalate is used for the bottle body. As the handle label 30, as in the first embodiment, a paper having a thickness of 0.3 mm as a base material and an adhesive (ethylene-vinyl acetate) and a peeling varnish separately applied on the back surface were used.

Similar to the first embodiment, the handle label has a quadrangular shape as shown in FIG. 3, and is divided into two vertical cuts 32 at the center and at the center. A grip portion 31 having a shape that is gradually expanded toward the outside is provided, and a rising portion 34 defined by a ┗┛-shaped cut 33 is provided below the grip portion 31. A fold line L1 is provided at the upper end of the grip 31 and a fold line L6 is provided at the lower end.
In addition, on the extension of the straight part above and below the notch 32, bend line L2,
L3 is provided, and the fold line L2 and the fold line L4 connecting the upper ends of the fold line L3 are provided, and the rising portion 34 is provided with the fold line L5 extending inward from each upper end of the notch 33 to the notch 32. . Therefore, after the grip portion 31 and the rising portion 34 are raised, each fold line is bent, and the shape as a handle can be maintained, which is convenient. This grip 31
A peeling varnish is applied to the rising portion 34, while an adhesive is applied to the adhesive portion 35 (the hatched portion in FIG. 3).

In FIG. 7, 71 is one of the left and right split molds of the blow mold. There is a portion 72 for holding the handle label 30 on the inner surface of the cavity of this split mold 71.
The portion 73 (see FIG. 7A) that holds the grip portion 31 of the (the label may be held by suctioning by using a suction device by providing a suction hole in this recess 73) is the other portion 74 ( Figure 7
(See (b)).

Next, the molding process of this embodiment will be described. This example was also manufactured by the injection blow molding method similarly to the first example. That is, first, polyethylene terephthalate is injected at a resin temperature of about 230 ° C. from an injection nozzle into the cavity of a mold that is closed, and after cooling and solidification, the mold is opened and a test tubular molded product (preform
75) was created.

Subsequently, the preform 75 was biaxially stretch blow molded using the blow mold. That is, after opening the left and right split molds 71, the handle label 30 is transferred from a label supply device (not shown) and held on the inner surface of the cavity, and then heated to a stretching temperature (about 160 ° C to 170 ° C). Insert the preform 75 into a predetermined position, then close the left and right split molds 71, biaxially stretch the preform 75 with a stretching rod, blow compressed air, and press the expanded preform 75 against the handle label 30. The two were brought into close contact with each other. Thereafter, cooling air was blown from the air passage in the drawing rod to cool and solidify the bottle, and a bottle 50 with a handle label integrated with the handle label 30 was formed.

In this embodiment, of the inner surface of the cavity of the mold, the portion 73 that holds the grip portion of the handle label is the other portion 74.
Since it is more recessed, the bottle body portion facing this portion is formed in a shape protruding outward. Also,
The handle label 30 also protruded outward along the protruding shape of the bottle body 77, and was completely separated from the adhesive portion 35 of the label by the cuts 32 and 33. Since the peeling varnish was previously applied to the bottle body portion facing surfaces 76 of the grip portion 31 and the rising portion 34, the bottle body portion 77 floated up without being adhered.
Subsequently, when the grip 31 is raised, the rising portion 34 is also raised, so even if the bottle body 77 is protruding, there is a sufficient gap between the bottle body 77 and the handle label 30,
I could put my hand here.

[0024] Bottle 50 with a handle label created in this way
Had a content volume of 2000 ml, a body thickness of 0.2 mm, and a handle label thickness of 0.3 mm. Observation of 50 bottles with a handle label shows that the handle grips
Since the 31 and the rising portion 34 were completely separated from the adhesive portion 35 and floated from the bottle body, it was extremely easy to put a finger on the notch that forms the grip portion 31, and to grasp the grip portion 31 and the rising portion. Could cause 34. And 2000 bottles of liquid detergent are added to the bottle 50 with the handle label.
When filled with ml and repeatedly dispensed, handle label
No peeling of 30 was obtained, and good results were obtained.

[0025]

As described above in detail, according to the present invention, since the handle member is made of paper, the amount of plastic resin used can be reduced, and the bottle and the label are integrated by in-mold label molding. Therefore, the strength of the entire bottle does not decrease even if the amount of plastic resin used is reduced. Further, since the bottle has a concave portion or a convex portion, the buckling strength is improved. Moreover, the handle is formed into a shape that is convenient for transportation, and the grip can be easily raised to obtain a bottle with a handle label that is extremely easy to use. .
