Abstract

(57) [Summary] [Problem] To provide a storage container with a new structure that can stabilize the quality of a container and upgrade its quality, with less risk of dust and dirt adhering to a storage product such as a rubber roller, and with less occurrence of warpage and distortion. I do. SOLUTION: At least a pair of opposed frame walls 2a, 2c of a substantially quadrangular hollow frame 1 are provided with tapered hem portions 3, 3 which are tapered downward so that they can be stacked and fitted to each other. The bearing bars 4, 4 are arranged in a bridge-like manner on both sides of the hollow inside the hollow frame 1.
A suitable number of bearing recesses 5 and 5 are respectively formed on the base 4 and opposed to each other, and the whole is integrally formed by injection molding.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a storage container.

[0002]

[Prior art]

 Conventionally, storage containers for transporting precision rubber rollers, etc., consist of both a container body in which a plurality of mounting grooves for storage products such as rubber rollers are recessed in parallel, and a lid that is mounted on this. Both were manufactured by vacuum forming.

However, dust and dirt tend to accumulate in the mounting groove of the container main body in such a conventional storage container, and the dust and dirt may adhere to a storage product such as a rubber roller and deteriorate the quality. In addition, due to vacuum forming, warpage and distortion are likely to occur in each container, and the quality is not stable due to product variations, and there is a problem that the product is likely to generate burrs due to the punching process. .

[0004]

[Problems to be solved by the invention]

 The present invention was devised to solve this problem in view of the above-mentioned problems in conventional storage containers, and it is less likely that dust or dirt will adhere to storage products such as rubber rollers, and warpage will occur. It is an object of the present invention to provide a storage container having a new structure in which the quality of the container can be stabilized and the quality of the container can be stabilized and the generation of distortion is small.

[0005]

[Means for Solving the Problems]

 The configuration of the present invention for achieving the above object will be described with reference to an embodiment. The storage container of the present invention is constricted by at least a pair of opposing frame walls 2a and 2c in a substantially rectangular hollow frame 1. The tapered hem portions 3, 3 are vertically arranged so that they can be stacked and fitted to each other, and the bearing bars 4, 4 are respectively bridged on both sides of the hollow inside the hollow frame 1. A suitable number of bearing recesses 5, 5 are provided opposite each other on both bearing bars 4, 4, and are integrally formed by injection molding.

[0006]

[Embodiment of the invention]

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

[0007]

【Example】

 1 is a plan view of one embodiment of the storage container of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a vertical cross-sectional view illustrating a stacked state.

In the figure, a hollow frame 1 has a substantially quadrilateral shape in a plan view, and a pair of opposing frame walls 2a, 2c of the frame walls 2a, 2b, 2c, 2d constituting the four sides constrict. In a state where the tapered hem portions 3, 3 are vertically suspended and stacked one above the other, the hem portions 3, 3 of the storage container positioned on the upper side are in the storage container positioned on the lower side. It is configured to be fitted in the hollow frame 1 and positioned without lateral displacement.

On both sides of the hollow inside the hollow frame 1, opposing bearing cross rails 4, 4 are provided in a bridging manner between the frame walls 2 a, 2 c. An appropriate number of bearing recesses 5, 5 facing each other are respectively recessed.

In the hollow frame 1, grip portions 6 are integrally protruded from the frame walls 2 a, 2 b, 2 c, 2 d at appropriate locations such as on the right and left outer sides and up and down. Reference numeral 7 in the figure denotes a rib provided between the upper and lower grip portions 6, 6 on both left and right outer sides of the frame walls 2a, 2b, 2c, 2d. Reference numeral 8 denotes a rib disposed at an appropriate position between the frame walls 2a, 2c and the bearing cross rails 4, 4.

The entire structure described above is integrally formed by injection molding using a polypropylene resin or another thermoplastic synthetic resin as a molding material.

[0012] In the storage container of the present invention having the above-described configuration, the storage product R is provided in both the bearing recesses 5, 5 on both the bearing horizontal rails 4, 4 opposed to each other in the hollow inside the hollow frame 1. The projecting shafts at both end surfaces of the rubber roller or the like can be supported so as to be bridged between the bearing cross rails 4 and 4, and then each of the storage containers of the present invention can be further stored. They can be stacked on top of each other without play.

When the molding material is made of polypropylene resin, there is no generation of toxic gas at the time of incineration and the recyclability is excellent, as compared with the conventional molding material made of vinyl chloride resin. Is beneficial from.

[0014]

[Effect of the invention]

 The present invention has the above-described structure, so that dust and dirt do not accumulate in the storage container.Therefore, there is no danger of dust or dirt adhering to the storage product such as a rubber roller. Due to the molding, warping and distortion of the container, and furthermore, the occurrence of burrs is small, and the practical effects such as stabilizing the quality of the container and upgrading the quality can be obtained.
