JPH066215U - Synthetic resin container - Google Patents

Abstract

(57) [Abstract] [Purpose] We propose a container made of synthetic resin, which has good shape-retaining property when used and can be easily folded and disposed of as small waste when discarded. [Structure] A bending line 4 is provided at a predetermined position of the tubular body 2 so that the body 2 can be folded into a flat plate shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin container.

[0002]

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

 Containers for storing liquid cosmetics and the like are made of shape-retaining synthetic resin or glass, and conventionally, the contents are generally discarded after use. However, along with the deterioration of the garbage disposal situation in recent years, it is required to reduce the weight and bulk of waste as much as possible.

The present invention has been made in view of the above circumstances, and proposes a synthetic resin container that can be treated as waste in a small bulk.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the container according to the present invention comprises a mouth neck portion 3 standing upright from the upper end of a tubular body portion 2, a bending line 4 is provided at a predetermined position of the body portion 2, and the bending line portion 4 is bent. Thus, the body portion 2 is configured to be folded into a flat plate shape.

[0005]

[Action]

 By removing the suction pump 5 from the state shown in Fig. 1 and then folding the container 1 along the folding line 4, it can be folded into a flat plate as shown in Fig. 2 and treated as a small bulk waste. Can be done. At this time, the suction pump 5 mounted on the container 1 or the pouring cap 8 as shown in FIG. 6 can be reused for the replaced container 1.

【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. The container 1 is integrally formed of synthetic resin, and has longitudinal rectangular front and rear walls 2b and 2c and left and right side walls 2d and 2e extending from the four sides of a square plate-shaped bottom wall 2a. And a rectangular tube-shaped body 2 formed by extending a rectangular plate-shaped top wall 2f whose peripheral edges are connected to the upper edges of the left and right side walls, and a cylindrical mouth-neck portion from the center of the body top wall 2f. 3 is built up.

A bending line 4 is formed at a predetermined position on the body 2. Then, as shown in FIG. 2, both side walls 2d and 2e are recessed inward and the top wall 2f and the bottom wall 2a are folded inward by bending the body portion 2 at the bending line 4 portion. As described above, the body 2 can be folded into a flat plate shape. In the figure, 9 indicates a cap. The fold line 4 has a cross-sectional shape perpendicular to the longitudinal direction as shown in FIG. 3 in which the wall portion of the body portion 2 is bent inward and outward in a W shape to project when the container 1 is formed by a mold or the like. It was formed at the same time.

A suction pump 5 is detachably fitted to the container 1. This suction pump 5 has a mounting cap 6 screwed onto the outer circumference of the mouth / neck 3 so that a cylinder with a suction pipe (not shown) at the lower end is suspended into the body 2 and a nozzle at the upper end is provided. This is a well-known mechanism in which the push-down head 7 is projected upward and downward so that it can be moved up and down. By moving the push-down head 7 up and down, the liquid in the body 2 is sucked up and discharged from the nozzle of the head. It is configured as described above.

The bending line 4 is not limited to that of the above-described embodiment, and may have a cross-sectional shape in which the wall portion of the body portion 2 is bent inward and outward in an N-shape as shown in FIG. 4, for example. The wall portion of the body portion as shown in FIG. 5 may have a cross-sectional shape in which the wall portion of the body portion 2 is bent and projected inward in an inverted U shape. Instead, it suffices to form a groove having a cross-sectional shape in which the wall portion is bent and projected inward and outward. This type of fold line has good shape retention when a container containing liquid in the body is used, and it has good shape retention when the body 2 is folded at the time of disposal. Initially, some force is required, but the container 1 can be easily folded into a flat plate shape.

6 to 8 show another embodiment of the container according to the present invention. In this embodiment, the front half of the body top wall 2f is gradually inclined to the inclined surface and the body top wall The body portion 2 has a well-known shape in which the rear half portion is formed in a mountain shape having an inclined surface that gradually descends, and front triangular shaped concave portions are formed on both sides of this mountain shape portion. Further, due to the change in the shape of the body portion 2, the formation position of the bending line 4 is also different from that of the above-mentioned embodiment, and the folding form is also different from that of the above-mentioned embodiment. That is, as shown in FIG. 8, the central portions of both side walls and the central portion of the bottom wall are inwardly recessed and folded in a flat plate shape.

Further, the container 1 of the present embodiment is detachably attached with a known form of a pouring cap 8 with a lid 8a.

[0013]

[Effect of device]

 As described above, since the container of the present invention has the above-described configuration, the volume of the waste after the content liquid is used up can be made small, and it is a container suitable for the recent circumstances of waste disposal.

Further, if the bending line is configured as a groove-shaped bending line formed by bending the wall portion of the body portion inward and outward, it is compared with a bending line formed by simply thinning the wall portion. In addition, it has a good shape-retaining property while it is used, and it can be easily folded into a flat plate when discarded.
