Abstract

PROBLEM TO BE SOLVED: To solve problems that a large number of handle bodies are disordered in posture or stuffed when they are arranged and carried in manufacturing plastic bottles having handles by forming an abutting flat surface on a single side surface part of a tip part of a fitting arm projecting horizontally from both upper and lower sides of a grip part. SOLUTION: In a handle body 3 provided with fitting arms 32 and 33 projecting horizontally from both upper and lower sides of a grip part 31, an abutting flat surface 41 is formed at least on one side surface part of tip parts of the fitting arms 32 and 33. The tip part of the lower fitting arm 33 is preferably of a structure of an H-shaped section in which an inner side plate 51 and an outer side plate 52 are connected to each other through a center longitudinal rib 53. When a large number of handle bodies 3 are continuously arranged with the side surfaces thereof in contact with each other, and carried while collided with and pressed against each other, the handle bodies are brought into contact with the abutting flat surface 41 when the fitting arms 32 and 33 of the handle body 3 are collided with each other. This arrangement makes the handle bodies difficult to deviate in the vertical direction, and solves a problem that they are easily disordered in posture and stuffed in the movement.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a handle for use in a plastic bottle with a handle.

[0002]

2. Description of the Related Art In recent years, a plastic bottle with a handle in which a separate handle is attached to a bottle body made of a plastic such as polyester resin represented by polyethylene terephthalate, which is lighter and more impact-resistant than glass, has been put to practical use. In particular, a handle provided with a grip portion and mounting arms protruding laterally from upper and lower ends of the grip portion in a grip mounting recess formed on the side surface of the bottle body, and the tip of the mounting arm is grip-mounted. Plastic bottles with handles, which are mounted so as to be embedded in the walls in the recesses, are commercially available.

[0003] As shown in a partially cutaway side view of FIG. 3, a plastic bottle with a handle is provided in advance in a blow molding die with a grip portion 31 and a lateral direction from both upper and lower sides of the grip portion 31. A separate handle body 3 having mounting arms 32, 33 protruding from each other is set so that the tips of the mounting arms 32, 33 protrude into the blow molding die. The bottle body 1 is blow-molded at the same time, and at the same time, it is manufactured by a method in which the tips of the mounting arms 32 and 33 are wrapped by the bottle wall 20 and integrated. Projecting pieces 320, 330 are formed outward at the tips of the mounting arms 32, 33.
Reference numeral 330 also functions as a stopper to be embedded in the bottle wall 20.

When a handle body 3 for manufacturing a plastic bottle with a handle is conveyed to a blow molding die, as shown in a schematic rear view in FIG. Usually, a large number of the bodies 3 are continuously arranged so that the side surfaces thereof come into contact with each other, collide with each other, and are conveyed while being pressed against each other.

[0005]

However, a large number of the above-mentioned conventional grips are arranged in a row and hit each other.
Also, there is a problem in that the mounting arms 32, 33 projecting laterally from both the upper and lower sides of the grip portion 31 have an unbalanced shape, so that the posture is lost during movement and the jam is likely to be clogged.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that the mounting arms of the handle body are likely to overlap with each other, and that the posture is likely to collapse. The gist of the present invention is as follows. In a handle having a grip portion and an attachment arm projecting laterally from both upper and lower sides of the grip portion, the handle protrudes from at least one side surface of a tip portion of the attachment arm. A handle body having a flat surface for contact.

In the handle of the present invention, a flat surface for abutment is formed on at least one side surface of the tip of the mounting arm, and as shown in a schematic rear view in FIG. When a large number of grips 3 are continuously arranged so that the side surfaces of the grips 3 are in contact with each other, collide with each other, and are conveyed while being pressed against each other, when the ends of the mounting arms of the grips 3 collide with each other, the abutment flat. It is hard to be displaced in the vertical direction by contacting the surface, without overlapping,
Therefore, it is difficult for the posture to be lost during the movement during the conveyance to cause clogging.

In the present invention, as the handle, a polyester function represented by polyethylene terephthalate, polypropylene, polyethylene or the like can be used.

In particular, when the same polyester resin as that of the bottle body is used as the material of the handle body, it can be treated together with the body when it is collected and recycled, and recycled resin is used as the handle body. It is preferable because it can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 (a) is a front view showing an example of the handle of the present invention, FIG. 1 (b) is a side view of FIG. 1 (a), and FIG. FIG. 3 is a partially cutaway side view showing an example of a conventional plastic bottle with a handle.

In the present invention, as shown in FIGS.
1 and a gripper body 3 having mounting arms 32, 33 projecting laterally from upper and lower sides of the grip portion 31, and a flat surface for abutting at least one side surface of the tip of the mounting arms 32, 33. The handle body 3 is formed with a handle 41.

The abutting flat surface 41 is shown in FIGS. 1 (a) and 1 (b).
As shown in, any flat surface perpendicular to the transport direction may be used,
It can be formed on one side or both sides of the tip of the mounting arms 32, 33.

The size of the butting flat surface 41 is as follows.
A circular or polygonal shape having a thickness of about the tip of the mounting arms 32 and 33 to be formed is preferable because there is no adverse effect on the performance of the handle 3.

In the handle body 3 of the present invention, as shown in FIGS. 1A and 1B, the tip of the lower mounting arm 33, that is, the portion connected to the flange plate portion 4, is close to the distal end surface (see FIG. 1A). The inner plate 51 and the outer plate 5 up to a position of 4 mm or less from the tip surface).
It is preferable that a cross section perpendicular to the longitudinal direction, which is a transverse cross section connected to the second member by a central vertical rib 53, has an H-shaped structure.

In order to obtain sufficient strength without using the H-shaped structure, it is necessary to increase the thickness accordingly.
If the thickness is made large, dents (also referred to as sink marks) are likely to occur particularly on the tip end surface of the flange plate portion 4 due to shrinkage in the cooling process when injection-molding the handle body. Because it is not noticeable. Although not shown, the upper mounting arm 32 is also similarly moved to near the distal end surface.
It is preferable that a cross section perpendicular to the length direction, which is a cross section, be an H-shaped structure.

In order to manufacture the handle 3, an injection mold (not shown) which is composed of a movable mold and a fixed mold and which can be divided from a portion corresponding to the center of the handle 3 is used. Usually, the grip portion 31 and the lower mounting arm 3
3 and the like connect the inner plate 51 and the outer plate 52
When the cross section perpendicular to the length direction, which is the cross section connected by the arrow, has an H-shaped structure, an undercut portion which is resistant to the dividing direction of the injection mold and the pulling direction of the product handle 3 does not occur. There is also an advantage that the step of taking out the product handle body 3 by dividing the mold becomes easy.

[0018]

According to the handle of the present invention, a flat surface for abutment is formed on at least one side of the tip of the mounting arm, so that the sides of the handle come into contact with, for example, a guide belt. When many are continuously arranged and collide with each other, and are conveyed while pressing, when the tips of the mounting arms of the handle body collide with each other, they do not easily shift in the vertical direction by contacting the abutting flat surface, They do not overlap, and therefore are less likely to be stuck in the posture during movement during transportation.
