In the illustrated example, recesses 12 are formed on both sides of the front plate 1a, and two protrusions (one in total) are provided at the upper ends of these recesses 12. A recess 12 may be formed in the recess 12, and one protrusion may be provided at the upper end of the recess 12.

The rear plate 1b is provided with a receiving portion 13 for a support shaft portion 22 provided on the lid body 2, which will be described later, on the outer side of the upper end. In the illustrated example, the receiving portions 13 are approximately inverted U-shaped with receiving protrusions 13a formed thereon, and protrude from the upper ends of both sides of the rear plate 1b, two in total. One piece may be provided protruding from the upper end of the center portion of 1b.

The lid body 2 is made of a transparent, translucent or opaque synthetic resin plate, and has a substantially rectangular shape with a lower opening consisting of a lower front frame 2a, a lower rear frame 2b, a lower left frame 2c, a lower right frame 2d, and a top plate 2e. It is used as a lid. This lid body 2 is configured such that the rear lower frame 2b can be returned to the original position by the coil portion 3a of the compression torsion coil spring 3, and can be slid laterally (left and right) to the rear plate 1b of the box body 1. At the same time, the upper opening of the box 1 is opened upward.

The lower front frame 2a is provided with an engaging portion 21 projecting from the lower end of a hanging portion 21a shaped like a leaf spring and having a protrusion 21b formed therein. In the illustrated example, the engaging portions 21 are two in total, one on each side of the lower front frame 2a, but one engaging portion 21 is provided protruding from the center of the lower front frame 2a. Good too. Note that the contact surfaces of the protrusions 21b of the engaging portion 21 and the protrusions 11 of the front plate 1a are tapered (see FIG. 6) so that they can be easily engaged and disengaged.

A support shaft 22a is provided on the rear lower frame 2b so as to protrude from a support shaft portion 22 in parallel with the rear lower frame 2b. In the illustrated example, two support shafts 22a are provided, one on each side of the rear lower frame 2b, in total, but one support shaft 22a may be provided protruding from the center of the rear lower frame 2b. good.

A mark 23 indicating the sliding direction of the lid 2 is provided on the top plate 2e. In the illustrated example, the mark 23 is a substantially triangular recess that can be slid by placing a finger on the recess, but an arrow may be added to the top plate 2e to simply indicate the sliding direction. It may be as shown. Further, the mark 23 may be provided on the lower front frame 2a.

The compression torsion coil spring 3 is made of an elastic linear body made of synthetic resin or metal, and has a fixed arm 3b protruding from one end of the coil portion 3a, and an operating arm 3c protruding from the other end of the coil portion 3a.

The coil portion 3a is rotatably supported by a support shaft 22a of the support shaft portion 22 of the lid body 2, and is a space formed between the receiving portion 13 of the box body 1 and the support shaft portion 22 of the lid body 2. It is fitted into S without any gaps.

When the compression torsion coil spring 3 is twisted, the fixing arm 3b is fixed to the fixing hole 14 formed in the rear plate 1b of the box body 1, and the action arm 3c is fixed to the back side of the top plate 2e of the lid body 2. is in contact with.

In addition, when two of the support shafts 22a are provided protruding from the rear lower frame 2b of the lid body 2, the coil portion 3a of the compression torsion coil spring 3 is inserted into one of them as shown in the figure. However, the coil portion 3a of the compression torsion coil spring 3 may be inserted into both of them.

By doing this, the lid body 2 is positioned to exactly cover the opening of the box body 1 by the coil portion 3a of the compression torsion coil spring 3, and the action arm 3c of the compression torsion coil spring 3 It is always biased upward.

Therefore, in the storage container of the present invention, when the lid 2 is slid in a lateral direction that compresses the coil portion 3a of the compression torsion coil spring 3, the protrusion 21b provided on the lid 2 and the protrusion 11 provided on the box 1 come together. The position shifts and the engagement is released, and the lid body 2 is rotated upward by the biasing force of the action arm 3c of the compression torsion coil spring 3. At this time, the compression of the coil portion 3a of the compression torsion coil spring 3 is released, and the coil portion 3a returns to its original state, and the lid 2 also returns to its original position before sliding, and the projection provided on the lid 2 21b returns to the original position where it engages with the engagement protrusion 11 provided on the box body 1.

Then, when the lid 2 is rotated downward from the open state with a force that overcomes the biasing force of the action arm 3c of the compression torsion coil spring 3, the protrusion 21b provided on the lid 2 and the box A protrusion 11 provided on the body 1 is engaged to close the lid body 2.

The usage state of the storage container of the present invention configured as described above will be explained in detail based on the drawings.

First, in the storage container of the present invention, in the state shown in FIGS. 1 to 4, the protrusion 21b of the engaging portion 21 of the front lower frame 2a of the lid body 2 engages with the protrusion 11 of the front plate 1a of the box body 1. Thus, the lid body 2 is in a closed state.

From this state, put your finger directly on the lower left frame 2c or the mark 23 of the lid body 2, and as shown in FIGS. When it is slid in the right direction in the figure, the protrusion 11 on the front plate 1a of the box body 1 and the protrusion 21b on the engagement portion 21 of the front lower frame 2a of the lid body 2 are disengaged.

When the protrusion 11 on the front plate 1a of the box body 1 is disengaged from the protrusion 21b on the engagement portion 21 of the front lower frame 2a of the lid body 2, hang it on the lower left frame 2c or the mark 23 of the lid body 2. When the user removes his/her finger, the lid body 2 is rotated upward and opened by the biasing force of the action arm 3c of the compression torsion coil spring 3, as shown in FIGS. 10 to 12. Note that when the lid 2 is opened, the coil portion 3a of the compression torsion coil spring 3 is decompressed, the coil portion 3a returns to its original state, and the lid 2 is moved to the position of the box 1 before sliding. It has returned to a position that just covers the upper opening.

From the open state of the lid 2, put your finger on the top plate 2e of the lid 2 and rotate the lid 2 downward with a force that overcomes the biasing force of the action arm 3c of the compression torsion coil spring 3. 13 to 15, the projection 21b of the engaging portion 21 of the front lower frame 2a of the lid body 2 comes into contact with the projection 11 of the front plate 1a of the box body 1. Therefore, when the lid body 2 is strongly pressed downward with a finger from this state, the tapered contact surface of the protrusion 21b slides on the tapered contact surface of the protrusion 11, and both protrusions 11 and 21b engage with each other. Then, the lid body 2 is in the closed state as originally shown in FIGS. 1 to 4.

A large number of the storage containers of the present invention can be stored in the carrying case 4 in rows and columns, as shown in FIG.

The mobile case 4 has vertical and horizontal storage recesses (not shown) in which the box 1 of the storage container can be stored inside the box 5, and a large number of storage containers can be stored with the lid 2 closed. In this case, a small gap O is created between each storage container in which the lid 2 can slide.

Therefore, in the storage container of the present invention, the lid 2 can be opened and closed by the simple operation described above, so that there is a small gap O in which the lid 2 can slide between each storage container stored in the mobile case 4. As long as it's empty.

Since the storage container of the present invention is configured as described above, the lid 2 can be easily opened and closed, and even when a large number of containers are stored in the carrying case 4, the lid 2 can be opened and closed easily. It became possible to do it successfully.
