Abstract

(57) [Summary] [Structure] In a blow-molded bottle 1 in which a handle mounting recess 2 is formed on an upper side surface and a handle 3 is mounted in the recess 2, a handle mounting portion lower part 21 below the handle mounting recess 2 is formed.
A plastic bottle with a handle characterized in that an uneven surface 4 extending in the circumferential direction is formed on the. [Effect] Not only in an empty bottle but also in a bottle filled with a beverage or the like, a rib effect is generated by the circumferentially uneven surface 4,
The deformation of this part is greatly reduced, and as a result, the handle 3
It also has the effect of stabilizing the fixation of.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic bottle having a handle attached to the bottle separately from the bottle.

[0002]

2. Description of the Related Art Since a large plastic bottle becomes inconvenient to handle, a bottle having a part of the main body formed into a handle is used for beverages and the like. However, in a bottle made of polyester resin such as polyethylene terephthalate, it is difficult to integrally mold the handle with the bottle body. Therefore, as shown in the front view of FIG. 1, a concave portion 2 is formed above the bottle 1 and the concave portion 2 is formed in the concave portion 2. A bottle fitted with a separate handle 3 is used.

[0003]

However, the lower portion 21 of the handle mounting portion below the handle mounting recess is likely to be largely stretched during blow molding, and therefore the lower portion 21 becomes thin and is deformed by external force, reduced pressure, heat or the like. There was a problem that it was easy.

[0004]

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problems and to improve the strength by the rib effect by forming an uneven surface extending in the circumferential direction in a portion which is easily stretched and whose thickness is thin. The outline is that in a blow-molded bottle in which a handle mounting recess is formed on the upper side surface and the handle is mounted in the recess, the unevenness extending in the circumferential direction is formed in the lower part of the handle mounting part below the handle mounting recess. It is a plastic bottle with a handle characterized by forming a surface.

The present invention will be described below with reference to the drawings. 1 is a perspective view of a plastic bottle with a handle of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a sectional front view thereof.

The present invention, as shown in FIGS. 1 to 3, has a handle mounting recess 2 formed on the upper side surface thereof, and a blow molding bottle 1 having a handle 3 mounted in the recess 2 is located below the handle mounting recess 2. A plastic bottle with a handle, characterized in that an uneven surface 4 extending in the circumferential direction is formed on a lower part 21 of the handle attaching portion.

A handle mounting recess 2 is formed on the upper side surface of the blow molded bottle 1, and a handle 3 is provided in the recess 2.
It is attached by appropriate means such as mechanical fitting and adhesion. In the examples of FIGS. 1 to 3, there is used a method in which a handle 3 which has been previously molded by injection molding or the like is set in a blow molding die, and at the same time as the blow molding, the bottle wall is entangled and attached to the handle.

A concave-convex surface 4 extending in the circumferential direction from the center to the left and right surfaces is formed on the lower part 21 of the handle mounting portion below the handle mounting recess 2. The concave-convex surface 4 is formed in a shape corresponding to the surface of the blow molding die and can be applied simultaneously when the bottle 1 is blow-molded. The uneven surface 4 may be provided over the entire left-right direction of the lower part 21 of the handle attaching portion as shown in FIG. 1, or may be provided so as to fit within the width of the handle 3.

Generally, the pitch of the uneven surface 4 is 2 to 3 mm, and the depth of the unevenness is 1 to 2 mm. The effect greatly reduces the deformation of this part.

[0010]

According to the present invention, in a blow-molded bottle in which a handle mounting recess is formed on the upper side surface and the handle is mounted in the recess, an uneven surface extending in the circumferential direction is formed below the handle mounting recess below the handle mounting part. Since it is a plastic bottle with a handle, it is easy to be stretched greatly when the bottle is molded and the wall thickness is thin. However, in a bottle filled with a beverage or the like, the deformation of this portion is greatly reduced, and as a result, the grip is more stably fixed.
