Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle mounting structure for a synthetic resin container.

[0002]

2. Description of the Related Art In general, relatively large PET (polyethylene terephthalate) bottles such as containers for soy sauce and alcoholic beverages are sometimes provided with a handle for easy holding. As such a handle, 3-15
No. 339 is disclosed.

As shown in FIGS. 4 and 5, the handle is divided into two parts in the longitudinal direction to form one handle 10 and the other handle 11, and these one handle 10 and the other handle 1 are provided.
A belt 1 wound around the outer periphery of the container 1
2 and 13 are respectively extended, and one handle 10 and the other handle 11 are connected via the belts 12 and 13. Then, the one handle 10 and the other handle 11 are fitted together with the belts 12 and 13 wound around the container 1 to complete the process.

[0004]

By the way, in the above configuration, a belt is used as a method of connecting the container and the handle. However, the belt is not a part to be directly gripped, but an incidental one. It is desirable to omit these in terms of effective use of materials.

The present invention has been made in view of the above circumstances, and provides a handle mounting structure in a synthetic resin container which can be manufactured at low cost without requiring a belt or the like attached to the handle. Is a technical issue.

[0006]

Means for Solving the Problems The present invention has the following configuration in order to solve the above technical problems. That is, while providing two or more convex portions 2 along the longitudinal direction of the container 1 on the side surface of the container 1 made of synthetic resin, a handle 4 having three concave portions with a bottom is formed, and a bottom portion of the concave portion 3 is formed. At the position where the mounting hole 6 was inserted through the convex portion 2, a large diameter portion 7 was formed at the top of the convex portion 2 at a position where the mounting hole 6 was inserted through the convex portion 2.

To form the large diameter portion 7, the concave portion 3
For example, a hot plate press or the like may be inserted through the opening to abut on the top of the convex portion 2 to soften it and crush it.

[0008]

As described above, the large-diameter portion 7 is formed at the top of the convex portion 2 at the position where the mounting hole 6 provided in the handle 4 is inserted into the convex portion 2. 1 can be firmly attached. In this case, since the handle 4 is directly attached to the container, no useless material for attachment is used.

Since the large-diameter portion 7 is located at the back of the concave portion 3, it is difficult to see from the outside and the appearance is good. Further, since the large-diameter portion 7 protruding from the deep portion of the concave portion 3 is formed, there is an advantage that no protruding portion is formed on the surface, and the large-diameter portion 7 can be formed into a free shape and thickness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The container 1 made of synthetic resin is made of PET, and is formed by blow molding. A mouth portion 1a is formed at the top of the container, and a concave portion 1b is formed on a side surface of the container 1 as an escape when a handle is attached. The concave portion 1b has two convex portions 2, 2 along the longitudinal direction of the container 1.
Are formed.

The protrusions 2 are respectively formed at portions where the handle 4 is to be attached, and are sucked from the outside when the container 1 is blow-molded or in a softened state.
As shown in FIG.

The handle 4 has a central portion in a plate shape, and both end portions project in a direction perpendicular to the central portion to form a thick box. Of these, the end located at the top of the container 1 is curved to give a sense of unity with the container 1. Recesses 3 with bottoms are formed at both ends of the handle 4, and the recesses 3 are deep enough to reach almost opposite sides of both ends. At the bottom 5 of the recess 3, a mounting hole 6 is formed which matches the position of the projections 2, 2.

The mounting hole 6 is connected to the protrusion 2,
2, a large diameter portion 7 is formed at the top of the convex portion 2. In this formation, as shown in FIG. 5, a cylindrical hot plate press 20 is inserted from the opening of the concave portion 3 and abuts on the top of the convex portion 2 to press and crush it while softening it.

In this case, since the convex portion 2 provided in the deeply recessed portion 1b is processed so that the large-diameter portion 7 is formed in the deep concave portion 3, the shape, thickness and the like of the convex portion 2 can be freely determined. And this does not protrude outside the container and does not interfere. Therefore, the handle 4 can be fixed in a state having sufficient strength.

As described above, the handle 4 is attached to the container 1,
Directly and firmly attached. In addition, since the minimum necessary shape and mounting method for mounting are adopted, there is no need to use useless materials such as belts and the cost is reduced. In addition,
Since the large-diameter portion 7 is located at the back of the concave portion 3, it is difficult to see from the outside, and the appearance is good.

[0016]

[Effects of the Invention] As described above, according to the present invention, since the container and the handle are configured to directly engage with each other, a belt or the like attached to the handle is not required, and the container can be configured with a minimum of materials. it can. Therefore, it can be manufactured at low cost.
