The present invention relates to a cassette storage case consisting of an inner box for storing a tape cassette and an outer box for inserting the inner box.

In general, the cassette storage case has a high frequency of storing or taking out the cassette, so that the cassette can be easily stored and taken out, and the strength is sufficiently preserved.

For example, FIGS. 1 and 2 show a perspective view of such a conventional cassette storage case. In FIG. 1, 1 is an outer box of which one side is opened, and the front plate 1a and the back plate 1b of the outer box. An arcuate cut-off part 2 is provided at the opening edge. The plate as shown in the opening edge side of the outer box 1 is bent The opening edge side of the inner box 4, which is shaped like a child and holds the cassette 3 between the front plate 4a and the back plate 4b, is inserted. In the cassette storage case having such a configuration, when the inner box 4 is inserted into the outer box 1, the opening edges thereof correspond to each other linearly, so that the opening edges are simultaneously joined to a plurality of points and the insertion is not performed smoothly. have. In particular, when the paper is warped and the openings of the front plate 4a and the back plate 4b are widened to the outside, the defects are remarkable. On the other hand, when the inner box 4 is extracted from the outer box 1, the front plate 4a and the back plate 4b of the inner box 4 faced with the notch 2 are pinched by fingers, but when the notch 2 is less, the front plate 4a and the back plate 4b. There was an unreasonable point in taking out the cassette that the cassette 3 intervened in between could not be strengthened and the cassette 3 was left in the outer box 1.

2 shows another conventional example, while the outer box 1 is as shown in FIG. 1, but the inner box 5 bends the plate body. It is in the shape of a child, and only the front piece is projected so that the center part of the side surface of the side of the opening side of 5a and the back plate 5b protrudes, and the protruding piece 6 faces said notch 2. In the cassette storage case having such a configuration, when the inner box 5 is inserted into the outer box 1, the protruding pieces 6 are caught in the notch 2 at the side edges of the opening side, so that the insertion operation is not smooth, Force will damage both outer box 1 and inner box 5. In addition, if the jammed condition is repeated, the shape of the notch 2 or the protruding piece 6 may be disturbed, and the hair may be severely formed at the end edge, which makes the borrowing operation extremely difficult. Moreover, the extraction by the clamping of the cassette as described above becomes difficult.

The present invention is designed to solve these conventional drawbacks. Therefore, the present invention facilitates the insertion of the inner box for accommodating the cassette into the outer box, and the side edge of the side of the inner box and the side of the opening of the outer box are fused to damage the inner box and the outer box. To provide a durable cassette storage case. Hereinafter, the present invention will be described with reference to specific embodiments shown in the drawings.

3 shows a cassette storage case according to the present invention, which is configured as an inner box 12 for holding the outer box 11 and the cassette 10 in a narrow manner, and shows the upper body with the inner box 12 taken out of the outer box 11.

The outer box 11 and the inner box 12 constituting the present invention are thick paper, or the outer box 11 and the inner box 12 is coated with a synthetic resin on a thick paper to facilitate the insertion and extraction of the outer box 11, the inner box 12 smooth, such as a flat synthetic resin It is formed as a member.

Therefore, the outer box 11 has an opening 11c in which the inner box 12 is extracted and inserted into the side as shown in FIG. 3, and constitutes the outer box 11, and the opening 11c side of the front plate 11a and the rear plate 11b facing each other. Each of the side edges 13 and 14 of the front plate 11a and the rear plate 11b has a < -shaped inclined portion so that the width gradually narrows toward the center from the upper and lower edges. Therefore, each of the side edges 13 and 14 of the front plate 11a and the rear plate 11b is the first inclined portions 13a and 14a inclined toward the center at the lower end and the second inclined portions 13c and 14c inclined toward the center at the upper end. The first and second inclined portions 13a, 14a, 13c, and 14c are inclined at the same inclination angle, and the central portion where the first and second inclined portions 13a, 14a, 13c, and 14c intersect is an arcuate portion. It is formed as 13b, 14b.

Meanwhile, the inner box 12 inserted into the outer box 11 is formed by bending a plate-like object 112 such as a thick paper into a c-shape so as to be formed as shown in FIG. Alternatively, two fold lines 101 and 102 are provided at parallel intervals approximately equal to the thickness W ₁ of the cassette 10 accommodated in the plate-shaped object 112 formed as shown in FIG. In 102, the plate-shaped object 112 is folded in a U-shape, and the front plate 12a and the back plate 12b are spoken on both sides of the side plate 103 sandwiched by the fold lines 101 and 102 to form the inner box 12 as shown in FIG. . The faceplate 12a and the backplate 12b of the inner box 12 have different shapes, and the backplate 12b is formed larger than the faceplate 12a, so that the side edges 18 of the opening 15a of the backplate 12b are positioned ahead of the side 15 of the faceplate 12a. It protrudes. And the side surface 15 of the opening part 15a side facing the side plate 103 of the front plate 12a of the inner box 12 is continued to the arc-shaped part 17 in succession to the inclined part 16 and the lower side of the inclined part 16 which widen the said front plate 12a from top to bottom. The side edges 18 of the openings 15a of the rear plate 12b facing the front plate 12a are formed at an inclined portion 19 which extends the rear plate 12b from the top to the central portion thereof, and at the lower end portion continuous to the inclined portion thereof. 20 is formed. In the vertical section 20, the width of the backplate 12b is approximately equal to the maximum width of the outer box 11. In addition, the front panel 12a and the rear panel 12b may be formed in opposite shapes to each other.

Thus, in this embodiment, the inclination angle β with respect to the vertical axis of the inclined portion 16 formed on the side edge 15 of the front plate 12 of the inner box 12 is the edges 13 and 14 of the front plate 11a and the rear plate 11b of the outer box 11, respectively. The inclination angles α of the first and second inclined portions 13a, 14a, and 13c, 14c of are formed as shown in FIG. Incidentally, the inclination angle α of the outer box 11 and the inclination angle β of the inner box 12 may be related to α <β, and are arbitrarily changed according to the selection constituting the outer box 11 and the inner box 12. In particular, it changes depending on the rigidity, softness and thickness of the material, and the size of the outer and inner boxes. In addition, the angle of inclination with respect to the vertical side of the inclined portion 19 formed on the side edge 18 of the rear plate 12b of the inner box 12, the same shape as the front plate 12a, the side edges 13, 14 of the front plate 11a and the rear plate 11b of the outer box 11, respectively. The first and second inclined portions 13a, 14a, 13c, and 14c are formed at or substantially the same with respect to the inclined angle α. The points from the inclined portion 19 to the vertical portion 20 at the side edge 18 of the rear plate 12b are positioned to substantially correspond to the arcuate portions 13b and 14b of the edges 13 and 14 of the outer box 11, respectively.

In the above-described configuration, the tape cassette 10 is stored in the cassette storage case according to the present invention so that the tape cassette 10 is sandwiched between the front plate 12a and the rear plate 12b of the inner box 12, and inserted into the inner box 12 to insert the inner box 12. It is inserted into the outer box 11c through the opening 11c. For example, first hold the bottom of the inner box 12 with the thumb and index finger, first insert it into the opening 11c between the front plate 11a and the rear plate 11b of the outer box 11 in the vertical portion 20 on the rear plate 12b side. Position it as shown in 4 degrees. Therefore, the vertical portion 20 of the rear plate 12b is gradually inserted from the bottom side edge 14 of the rear plate 11b side of the outer box 11 to the deepest portion of the side edge 14 along the inclined portion 14a of FIG. It reaches the arc part 14b. The back plate 12b is then guided while the inclined portion 19 continuing the vertical portion 20 is restrained inside the outer box 11 by the second inclined portion 14c at the top of the cutout portion 14. Then, the inner box 12 is inserted into the outer box 11, and the arcuate portion 17 provided on the front plate 12a of the inner box 12 is formed by the gap as described above, and the lower side edge 13 on the front plate 11a side of the outer box 11 is placed. One reaches the inclined portion 13a and becomes as shown in FIG. That is, the arc-shaped portion 17 of the inner box 12 is guided by the clamping operation to be inserted into the first inclined portion 13 on the lower side of the side edge 13 installed inclined on the front plate 11a of the outer box 11. However, by this insertion, the first inclined portion 13a acts as if the side edge portion 15 of the front plate 12a of the inner box 12 is always suppressed on the rear plate 12b side. Therefore, the inclination angles of each side edge 15 and 18 of the front panel 12a and the back panel 12b of the inner box 12 are different from the inclination angles of the side edges 13 and 14 of the front panel 11a and the rear panel 11b of the outer box 11 and also the front panel of the inner box 12 12a and backplate 12b are different in shape, so when inserting inner box 12 into outer box 11 as described above, inner box 12 and edges 15 and 18 respectively and side edges 13 and 14 of outer box 11 always touch at one point do. Therefore, the inner box 12 is inserted into the outer box 11, so the resistance is small, so that an extremely smooth insertion can be performed.

In addition, in the side plate 103 for addressing the front panel 12a and the rear panel 12b of the inner box 12, a title display stage 21 for entering a title rearranging number or the like is provided. In addition, as shown in FIG. 7, a memo column 22 capable of recording the contents of the cassette tape 10 is provided on the inner surface on which the inner box 12 is to be deployed so as to arbitrarily record music titles, composer names, and the like.

However, when the inner box 12 is taken out from the outer box 11, the front plate 12a and the rear plate 12b of the inner box 12 facing outward from the opening edge of the outer box 11 are held by fingers. That is, it can grab near the center part of the inner box 12, and taking out is extremely easy.

8 is a front view of a cassette storage case showing another embodiment of the present invention and shows a state in which the inner box 23 is inserted into the outer box 11. In this example, arcuate portions 26 and 27 are formed in the side edge portions 24 and 25 on the opening side of the front plate 23a and the rear plate 23b of the inner box 23 protruding from the center portion. These arc-shaped portions 26 and 27 are arranged as corresponding to the maker side edges 13 and 14 of the outer box 11 formed as described in the above embodiment.

According to this configuration, the tape cassette is inserted between the front plate 23a and the rear plate 23b of the inner box 23, which inserts the inner box 23 into the outer box, and is pinched with the fingers, and the arc-shaped portion 27 is first placed on the rear plate of the outer box 11. Insert from side edge 14 (see Figure 3) in 11b. The opening side edge 25 is inserted into the outer box 11 with respect to the rear plate 23b initially inserted with respect to the first and second inclined edge portions 14a and 14c of the side edge 14. Subsequently, the arc-shaped portion 26 of the bottom plate 23a is guided in the form of being immersed in the side edge 13 on the front plate 11a side of the outer box 11 by finger pinching, and the opening side edge part is pressed while pressing the inner box 23 into the outer box 11. 24 is guided with one point contact with respect to the 1st and 2nd inclination parts 13a and 13c of notch 13 of outer box 11, and gradually the side edge part 24 is accommodated in said outer box 11. In this case, when the inner box 23 is inserted into the outer box 11, the resistance is small and extremely smooth insertion is performed.

The first and second side edges 13a and 13c of the inner side 23 of the inner plate 23a and the side edge 13 of the outer box 11 are respectively in contact with the lower first inclined portion 13a and the upper second inclined portion 13c so as to facilitate insertion. Hold the inclination angle of the side edge 24 large so that the inclined portions 13a and 13c of 2 and the side edge 24 of the inner box 23 do not become the same inclination angle. For example, in this case, the inclination angle δ with respect to the vertical sides of the side edges 24 and 25 formed on the front plate 23a and the rear plate 23b of the inner box 23 is δ≥α + with respect to the inclination angle α of the inclined portion 13a of the outer box 11. It is good to set it as 3 degrees. It goes without saying that the leading edges 28, 29 can be made as shown in FIG. 9 in place of the arcs 17, 26, 27 of the inner boxes 12, 23 shown in the above embodiments. In addition, the inner box 23 extends the back plate 23b, and as shown in FIG. 10, the cassette 30, which is shaped as the opening and closing material of the opening and closing material, is taken out and the inner box 23 takes out the inner box 23 from the outer box 11. It is also possible to configure the cassette so that the cassette can be easily taken out without requiring a positioning force. In addition, the inner box 23 and the outer box 11 may be formed as a smooth member such as not only paper, but also coated with synthetic resin on paper and synthetic resin material. The present invention is effective when the front plate 23a and the rear plate 23b of the inner box 23 are prevented from twisting to cover the opening edge of the inner box 11 and the opening edge of the outer box 11.

As described above, the present invention provides an outer box in which the opening edge is inclined so as to facilitate pinching of the inner box for accommodating the cassette, and an opening edge having a different inclination angle with respect to the inclination angle of the opening edge of the outer box. The inner box is flexibly accommodated in the outer box by facilitating insertion of the inner box into the outer box with the formed inner box. Therefore, the cassette can be stored and taken out smoothly and is extremely convenient for the user.
