Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin container with a handle.

[0002]

[Prior art] [Problems to be solved by the device]

 A synthetic resin container made of polyethylene terephthalate, etc. was formed by so-called biaxial stretching blow molding, in which a cylindrical bottomed synthetic resin substrate (parison) was stretched downward in the softened state and then blown into the mold. It is known that it is difficult to form a handle integrally with such a container. Therefore, conventionally, for example, an upper fitting member that covers and fits over the shoulder and upper part of the body of the container body and a lower fitting member that covers and fits the lower end of the body part of the container body are provided. It has been proposed that a member is constructed by straddling a handle having an upper part and a lower part fitted and fixed.

[0003] These containers make it easy to pour out the contents due to the presence of the handle, and on the other hand, they require a large fitting member, and many materials are used, resulting in a high material cost. And the weight is heavy.

Therefore, even if the handle is directly fitted to the container body without using the upper and lower fitting members, the container body formed by blow molding can be configured so that the handle can be fitted tightly and loosely. difficult.

The present invention proposes an excellent container with a handle which solves the above-mentioned drawbacks of the prior art.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the container of the present invention is formed by blow molding, and a pair of upper and lower projections 7 are provided on the rear surface of the tubular body 4 and the barbs 8 are post-processed on the periphery of each projection 7. And a container body 2 which is formed into an annular shape fitted around each of the projections 7, and a pair of fitting portions formed by projecting a barb 11 which engages with a barb 8 at the peripheral edge of the projection 7 on the inner surface. And a grip 3 having a gripping plate portion 10 between the fitting portions 9.

[0007]

[Action]

 By forming the container body 2 having the protrusions 7 by blow molding and then forming the barbs 8 on the periphery of the protrusions 7 by post-processing, the container body 2 is constructed to form a rigid and sharp barb 8. Then, the handle fitting portion 9 is tightly engaged with the barb 11.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which 1 denotes a synthetic resin container with a handle. The container 1 is composed of a container body 2 and a handle 3.

The container body 2 is formed by blow molding using a thermoplastic resin such as polyethylene terephthalate, and the mouth / neck portion 5 is erected from the center of the upper end of the cylindrical body portion 4, and the upper surface is formed on the rear portion of the body portion 4. A recess 6 for attaching a handle is formed which has openings on both side surfaces and a rear surface. At the beginning of blow molding, as shown in FIG. 2 (A), a pair of rectangular projections 7 are provided above and below the vertical wall surface of the recess 6 at a predetermined interval. Then, after the blow molding, as shown in FIG. 2 (B), the barbs 8 are attached to the rear end portions (the upper and lower edges, the left and right edges, and the upper and lower and left and right edges) of the protrusions 7. It is post-processed.

The barb 8 is formed by, for example, hot press molding after the container body is blow-molded, and has a sharp barb shape with rigidity. In addition, if the protrusion is formed at the time of forming the barbs on the periphery of the protrusion 7 during blow molding, the barbs can be formed more easily.

The handle 3 is made of synthetic resin and has a pair of rectangular frame-shaped fitting portions 9 fitted around the respective projections 7 of the container body 2. A U-shaped plate-shaped gripping plate portion 10 is laid over the. Further, a barb 11 that engages with each barb 8 of the container body 2 is projectingly provided on the peripheral edge of the inner surface of each mating part 9 so that each mating part 9 cannot be pulled out. In this embodiment, the handle 3 is attached to the container body 2 by elastically overcoming and engaging the respective barbs 11 with the barbs 8 of the container body projection 7.

3 and 4 show another embodiment of the present invention. In this embodiment, after the container body 2 is blow-molded as shown in FIG. 5 (A), the protrusions 7 are formed as shown in FIG. 5 (B). The handle 3 is attached before the barb 11 is formed, and then the barbs 8 are formed on the protrusions 3 as shown in FIG. 5 (C) so that the fitting portions 9 of the handle 3 cannot be pulled out and mounted. It is a thing. Therefore, a rectangular base 13 having a protrusion 12 on the periphery can be formed at the base end of each protrusion 7, and a holding metal fitting 14 can be fixed during press working in the direction of the arrow when forming the barb 8. I am doing it.

[0014]

[Effect of device]

 As described above, the container of the present invention is formed by blow-molding a container body in which a pair of upper and lower rectangular projections are projected on the rear surface of the tubular body, and then the barbs are post-processed on the periphery of each projection. The barb can be sharply formed despite the blow-molded container body, and it can be tightly and tightly engaged with the barb of the handle fitting part, which may cause inconvenience such as looseness of the attached handle. Absent.

Further, since the handle can be directly fitted to the container body without using the upper and lower fitting members unlike the conventional container of this type, it has the advantages of using less material and reducing the weight. Is.
