Abstract

PURPOSE:To make a handle part easier to grip, and at the same time, prevent a slipping between a bottle and a palm, and improve the handling property by a method wherein a handle part is formed by providing a pair of depressed parts by indenting both side parts of a body part inward, and an antislipping material is affixed around the handle part. CONSTITUTION:A biaxially oriented polyester bottle main body 1 is obtained by forming a parison made of a polyester resin such as polyethylene terephthalate resin, etc., by biaxial orientation blow-molding. Depressed parts 2 in which fingers can be inserted under a bottle gripping attitude are formed on both sides of a body part of the bottle main body 1, and a gripping part 3 which is easy to grip by a palm is formed. Then, as an antislipping material 4, on the bottle outer surface of the handle part 3 between the depressed parts 2, a hot melt adhesive 41 is affixed in a large number of dots. The hot melt adhesive 41 may be affixed into a band form, linear form or lump form. In this case, as the hot melt adhesive 41, ethylene-vinyl acetate copolymers, etc., are good, and for the affixing quantity, 1-2g per bottle is enough to impart an antislipping property.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biaxially stretch blow molded bottle made of a polyester resin such as polyethylene terephthalate.

[0002]

2. Description of the Related Art Biaxially stretched polyester bottles have been widely used as bottles for storing liquids such as soy sauce and whiskey, and in recent years, the bottles have tended to increase in size.

When a polyester bottle becomes large, it is not easy to carry it, to take out the contents, and the like, and it is difficult to form a through hole for inserting a finger in the bottle body as a handle because of the characteristics of the resin. Therefore, a polyester bottle with a handle, in which a handle separate from the body of the bottle is attached to facilitate handling, has become popular.

[0004]

However, the conventional polyester bottle with a handle has a problem in that it requires a special manufacturing process of attaching a separate handle to the bottle body, resulting in an increase in price.

[0005]

DISCLOSURE OF THE INVENTION The present invention is intended to obtain a cheap bottle by improving the handleability of the bottle by forming a pair of recesses corresponding to the grips on the bottle body. The gist of the invention is that two sides of the body of the bottle body are depressed inward to form a pair of recesses to form a grip, and a sliding material is attached around the grip. It is a stretched polyester bottle.

Thus, a pair of recesses are provided to form a gripping portion for easy grip, and when the bottle is gripped, the sliding material prevents slipping between the bottle and the palm,
This has the effect of improving handleability.

The present invention will be described below with reference to the accompanying drawings. 1 is a front view showing an example of the biaxially stretched polyester bottle of the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a front view showing an example of the biaxially stretched polyester bottle of the present invention,
FIG. 4 is a sectional view taken along line IV-IV in FIG.

As shown in FIGS. 1 to 4, the present invention forms a grip portion 3 by forming a pair of recesses 2 by recessing both sides of the body portion of the bottle body 1 inward, and the grip portion 3 is formed. Three
The biaxially stretched polyester bottle is characterized in that the sliding material 4 is attached to the periphery thereof.

In the present invention, the biaxially stretched polyester bottle body 1 is obtained by biaxially stretch blow molding a parison made of a polyester resin such as polyethylene terephthalate resin as shown in FIGS. Recesses 2 into which the fingers can be inserted in the bottle gripping posture are formed on both sides of the body portion of the bottle body 1, and as a result, gripping portions 3 that can be easily gripped by the palm are formed.

In the example of FIGS. 1 and 2, as the sliding material 4, a large number of hot-melt adhesives 41 are attached in a dot shape on the outer surface of the bottle of the grip portion 3 between the concave portions 2 and the concave portions 2. There is. The hot melt adhesive may be applied in a strip shape, a linear shape, or a lump shape.

Here, as the hot melt adhesive 41,
Any generally used can or base cup may be used, and an ethylene-vinyl acetate copolymer system, a polyester system, or the like is appropriate. Also, the amount applied is 1-2 per bottle.
g has a sufficient sliding effect.

Further, in the examples shown in FIGS. 3 and 4, as the sliding material 4, a supporting wall portion 42 having a shape substantially similar to the outer shape of the recess 2 is attached by the recess 2 of the bottle and the adhesive 5. is there.

The rigidity of the grip portion 3 and the bottle body 1 is increased by bonding and solidifying the supporting wall portion 42 and the adhesive 5 in the concave portion 2 and providing the supporting wall portion 42 with irregularities. As a result, there is an advantage that the bottle body 1 is less likely to slip when it is gripped and is easy to handle.

The support wall portion 42 is made of a thermoplastic resin such as polyethylene, polypropylene or polystyrene and can be molded by injection molding or the like. The surface of the support wall portion 42 has vertical, horizontal or lattice-like irregularities. Is preferred.

As the adhesive 5 for adhering the support wall portion 42 and the recess 2 to each other, an adhesive such as a hot melt adhesive or an epoxy resin may be interposed and solidified.

[0016]

As described above, according to the present invention, a pair of recesses are provided by forming both sides of the body portion of the bottle body inwardly to form a grip portion, and a sliding material is provided around the grip portion. Since it is a biaxially stretched polyester bottle, it is easy to hold the bottle with one hand due to the finger-insertable recesses formed on both ends of the body of the bottle body, and the sliding material around the gripping part. With the sticking, the bottle and the palm are less likely to slip and the handling such as taking out the contents is further improved.
