Description

[Detailed Description of the Invention] The present invention relates to an article storage case, and particularly to a case suitable for use as a shipping box between factories or within a company.

Conventionally, a cogitenna, which is integrated by injection molding, has been used as a case for such a box.

However, such a case is extremely expensive, lacks general-purpose properties, and has a weight of 6 kg (for example, a case with a capacity of 1001) weighs as much as 6 kg.

Therefore, it has become difficult to carry large containers.

In addition, in order to reduce the storage space when not in use, the sides are sloped so that the cross section has an inverted isosceles trapezoid shape.
They are stacked in several stages, but if too many are stacked, the upper and lower cases will be press-fitted into each other, making it difficult to separate them.

The present invention was developed in view of these problems, and involves bending a sheet-like body made of synthetic resin to form a base plate and four parts.
a tongue-like piece is formed by at least a part of a connecting piece that interconnects the four side plate parts, and the tongue-like piece is made to protrude from the outer surface of the side plate part; A frame is attached to the opening edge at the upper end of the side plate.

Therefore, products of various sizes can be produced in small quantities at a relatively low cost, and the weight can also be reduced.

To explain the present invention with reference to the illustrated embodiment, a so-called damp plastic sheet having a structure similar to that of cardboard is prepared and punched out to form the i′-bottom plate portion 1 (!) as shown in the figure. :,'The fourth side plate: part 3, which is connected to this bottom plate 1 part 1 through folding lines 2, respectively.
4, 5.6 are integrally formed; further two side plate parts 3
, 5 are connected with connecting pieces 8 on both sides via folding lines 7, respectively.

Each of the root portions of the connecting pieces 8 forms a cut line 9 that is approximately )-shaped, thereby forming four tongue-like pieces 10.
form.

The case body 11 is assembled by assembling the damp plastic sheet thus punched and formed, as shown in FIG.

In this assembly, the four side plate parts 3.4.5.6 are broken off at the bending line 2 from the bottom plate part 1, and the four side plate parts 3.4.
5 and 6' are connected to each other by a connecting piece 8.

At this time, the connecting piece 8 is positioned inside the side plate portions 4.6 and overlaps with the side plate portions 4,6.

Furthermore, the tongue-like piece 10 provided on the connecting piece 8 is connected to the side plate parts 4, 6.
overlap with the side plate parts 4 and 6 so as to be located on the outside of the side plate parts 4 and 6.

In this way, the connecting piece 8, the side plate part 4 or 6, and the tongue-shaped piece 1
0 by a connecting means, such as an eyelet or a stud.

Next, frames 12 are attached to the edges of the upper opening of the case body 11, that is, the upper ends of the four side plates 3, 4, 5, and 6, respectively, by molding synthetic resin, for example, vinyl chloride resin.

These four frames 12 have a U-shaped cross section and have downward openings, so that these four frames 12 have four side plate parts 3, 4, 5, 4, 4, 5, 3, 4, 4, 5, 4, 4, 4, 4, 5, 4, 4, 5, 4, 4, 4, 4, 5, 4, 4, 4, 4, 4, 5, . It will cover the upper edge of 6.

Since the four corners of these frames 12 are discontinuous, L-shaped corner reinforcing members 13 made of polypropylene are attached to the four corners of the frames 12 for reinforcement. will be done.

This corner reinforcing member 13 also has a U-shaped cross section like the frame 12, and is slightly larger than the frame 12, so that the reinforcing member 13 covers the corner portion of the frame 12. It will be installed on.

The reinforcing member 13, the frame 12, and the upper ends of the side plates 3, 4, 5.6 are connected to each other by connecting means such as rivets passing through them.

Each reinforcing member 13 has a shaft hole 14 formed therein, and the end portion of a member 15 is rotatably supported by the shaft hole 14, which is cut out from the iron rod and has both ends bent.

Note that the surface of the receiver member 15 is plated.

In addition, the bottom plate portion 1 and side plate portions 3 and 5 of the case body 11 are
An auxiliary plate 16 made of iron or steel is also fixed to the plate 16 by means of coupling means such as rivets.

This auxiliary plate 16 not only reinforces the case body 11 but also prevents the bottom surface of the bottom plate portion 1 from being worn out.

In this way, the case 18 is completed as shown in FIG.

This case 18 is used, for example, as a returnable box in a factory or the like, and as shown in FIG. 4, various articles such as mechanical parts 17 are stored in this case 18.
It is transported to the machine for the next process.

When a predetermined amount of parts 17 have been inserted, the receiver of this case 18 is used to place another case 18 on top of the member 15 and place the parts 17 into the upper case f8, as shown in FIG. can.

In this case, the upper case 18 is supported by the member 15, and the auxiliary plate 16 of the upper case 18 is supported by the member 15.
Since the receiver of the lower case 18 is in contact with the part member 15, the parts 17 in the lower case 18 will not be damaged or deformed, or the bottom of the upper case 18 will not be damaged. It is very convenient.

Also, when transporting this case 18, the receiver is the member 15.
The handle acts as a handle, allowing the work to be carried out smoothly.

When storing this case 18 when not in use, as shown in FIG. 4. 5. Since the receiver 6 is inclined, a large number of cases 1B can be stacked up and down by tilting the member 15 outward.

Moreover, at this time, since the reinforcing member 13 of the lower case 18 and the tongue-shaped piece 10 of the upper case 18 come into contact with each other,
The insertion depth of the upper case 18 is restricted, and the upper and lower cases 18 are not press-fitted.

Therefore, when used, they can be easily separated.

Further, since the main body portion 11 of the case 18 is made of a damper sheet, it is lighter than the case where the entire body is molded, and it is possible to manufacture a case with a volume of 1001 or more.

Further, the frame 12 and the corner reinforcing member 13 are made of molded pieces, but the frame 12 may be a long one and may be cut appropriately according to the size of the case 18, and the reinforcing member 13 may be made of a long piece.
It can be shared regardless of the size.

Furthermore, since the case body 11, which constitutes the majority of the case 18, is made of a punched sheet, the mold is inexpensive, so even if the quantity per lot is small, a low-cost case 18 can be obtained. .

Furthermore, since there is no part whose dimensions are regulated by the size of the case 18, the size of the case 18 can be changed freely, resulting in great versatility.

As described above, according to the present invention, since the main body portion of the case is made of a sheet-like body, the case is lightweight and can be produced in small quantities.

Furthermore, when the cases are stacked one on top of the other, since the tongue-shaped piece protrudes outward, the insertion depth is regulated and separation becomes easy.
