[Detailed description of the invention]

[0001]

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

[0002]

[Prior art]

As a synthetic resin container made of polyethylene terephthalate or the like, a so-called two-shaft in which a bottomed cylindrical synthetic resin base (parison) is stretched downward in a softened state and then blow-molded in a mold. Although those formed by stretch blow molding or the like are known, it is difficult to integrally form a handle in such a container. For this reason, conventionally, for example, an upper fitting member that covers and fits over the upper part of the shoulder and 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. There has been proposed a configuration in which a handle having an upper portion and a lower portion fitted and fixed is hung over each other.

[0003] In these containers, the presence of the handle makes it easy to pour out the contents and makes it easy to handle. On the other hand, the handle protruding larger than the body of the container hinders the transportation and storage, resulting in extra space. There was an inconvenience that required.

In addition, since the handle is fitted and fixed, play may occur at the fitted portion, and a large fitting member is required, so that a large amount of material is used, and the material cost is increased. . The present invention proposes an excellent synthetic resin container with a handle that has solved the above-mentioned disadvantages of the prior art.

[0005]

In order to solve the above-mentioned problems, the container according to the present invention raises the mouth and neck part 5 from the cylindrical body part 4 stretched in the biaxial direction, and the rear center of the body part 4. A container body 2 formed with a concave portion 6 for attaching a handle to
A bar-shaped grip 7 whose upper and lower ends are locked is laid over the upper and lower corners at the center of the opening of the recess 6, and is buried in the inner wall of the recess 6 via a connecting plate 8 protruding from the front surface of the grip 7. And a handle 3 extending from the embedded substrate 9, and both are integrally formed by insert molding.

[0006]

The handle 3 is composed of the upper and lower ends of the holding portion 7 which is engaged with the upper and lower corners at the center of the opening of the concave portion 6 of the container, and the embedded substrate 9 which is embedded and fused to the inner wall of the concave portion 6 of the container. Is firmly fixed without backlash.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention.
In the drawing, reference numeral 1 denotes a synthetic resin container with a handle. The container 1 includes a container body 2 and a handle 3.

The container body 2 is formed of a thermoplastic synthetic resin such as polyethylene terephthalate. The mouth and neck portion 5 is erected from the center of the upper end of a cylindrical body 4 which is biaxially stretched. A concave portion 6 for attaching a handle is formed in the center of the rear portion, and has both sides and a rear surface opened.

The handle 3 is integrally formed of synthetic resin and integrally fixed with the container body 2 by insert molding. As shown in FIG. 2, the handle 3 protrudes from the center of the front surface of the vertically long grip portion 7 in the vertical direction. A buried substrate 9 extending vertically from the end of the provided connecting plate 8 is extended. The upper surface of the grip portion 7 is formed in an upward hook shape that fits into the upper corner portion of the container body concave portion 6 to be abutted, and similarly, the lower surface is the lower corner portion of the container body concave portion 6 to be abuttedly fitted. It is formed in a downward hook shape that fits. Also, in order to increase the stability at the time of locking, the upper and lower locking plates 10a and 10b are protruded from the upper and lower front surfaces of the grip portion 7. In addition, the embedded substrate 9 has a large fixing strength when the upper and lower ends thereof are each deformed into a hook shape and embedded and fused.

The container 1 is obtained by placing the handle 3 constructed as described above at a predetermined position in a mold and insert-molding the same using a parison for forming a container. The obtained container 1 is embedded with the handle 3. The substrate 9 is buried and fused to the inner wall of the concave portion 6 of the container body, and the upper and lower ends of the grip portion 7 are fixed to the container body 2 by abuttingly engaging the upper and lower corners of the central portion of the opening of the concave portion 6.

FIGS. 3 and 4 show another embodiment of the present invention. In this embodiment, an arc-shaped concave portion 11 is continuously provided on the inner surface of the grip portion 7 and a finger gripping the grip portion 7 is moved to each concave portion 11. Handle 3
Is configured to be more easily held.

[0013]

As described above, in the present invention, the handle is housed in the concave portion of the container, so that it does not hinder the transportation and storage.

[0014] The handle is provided with a rod-shaped grip portion having upper and lower ends abutted and engaged with the upper and lower corners at the center of the opening of the container body concave portion, and via a connecting plate projecting from the front surface of the grip portion. The handle and the container body are integrally formed by insert molding, so that the handle can be securely fixed to the proper position of the container body. Moreover, there is no inconvenience such as being firmly fixed and rattling.

Further, the handle does not require any extra material and can be manufactured at low cost.
