Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper cassette tape cassette paper box for audio tape cassettes, video tape cassettes, etc., which can be easily incinerated, landfilled, or recycled.

[0002]

[Prior art]

 Conventionally, for audio tape cassettes and video tape cassettes, plastic tape cassette cases of various shapes have been widely used to protect magnetic tape, magnetic tape openings, reel shaft holes, and the like. For example, in Japanese Utility Model Publication No. 60-38539 relating to the applicant of the present application, an invention of an audio tape cassette case made of plastic with a front cover plate opening and closing type is proposed.

[0003]

[Problems to be solved by the device]

 In connection with recent waste disposal problems, there is a demand for a paperboard tape cassette paper box that can be easily incinerated, landfilled, or recycled instead of the conventional plastic tape cassette case. There is something.

[0004]

[Means for Solving the Problems]

 The present invention, as shown in FIG. 1 and FIG. 2, has a reel shaft fixed with two circular holes (12, 12), each of which is rectangular through fold lines (a, b, c, d). An upper surface inner plate (10) provided with an inner piece (11), and an upper surface outer plate (20) provided with reel shaft fixing outer pieces (21) by connecting side surface outer plates (22, 22) to the left and right, The back side plate (30) in which the folding pieces (31, 31) are connected to the left and right, the lower surface outer plate (40) in which the side surface inner plates (42, 42) are connected to the left and right, and the lower surface inner plate (50) A tape cassette paper box comprising a paper box blank made of paperboard, which is connected in order, and two plastic reel shaft fixing protrusions (60, 60) having a wide flange (61), First, insert the two plastic reel shaft fixing protrusions (60, 60) with wide flanges (61) into the two circular holes (12, 12) of this paperboard box blank and hold them. After folding, fold the two fold lines (a, d) into a mountain fold (the outer surface (printing surface) side becomes a mountain, the same hereafter) Then, the upper inner plate (10), the upper outer plate (20), the lower outer plate (40) and the lower inner plate (50) are glued to each other, and then four fold lines (b , c, e, e) are mountain-folded, and the left and right side outer plates (22, 22) and side inner plates (42, 42) are sandwiched by the left and right folding pieces (31, 31). The present invention provides a tape cassette paper box characterized by being pasted with glue.

[0005]

[Action]

 In the tape cassette paper box of the present invention, the crease line (g) is valley-folded (the outer surface (printing surface) side is a valley, the same applies hereinafter), and the crease line (f) is mountain-folded and glued to the reel. After the shaft fixing pieces (11, 21) are opened and the tape cassette (not shown) is inserted and accommodated, the two reel shaft holes (not shown) of the tape cassette are set to the two reel shaft fixing protrusions (not shown). When the reel shaft fixing pieces (11, 21) are closed so that they can be fitted into the tape, the tape accommodated by the two plastic reel shaft fixing protrusions (60, 60) has an appropriate elasticity. The cassette does not rattle, and the reel shaft fixing pieces (11, 21) can hold a stable closed state (the tape cassette does not pop out).

【Example】

FIG. 1 is a plan view of a paper box blank made of paperboard of a tape cassette paper box in an embodiment of the present invention. That is, a top inner plate (10) provided with a reel shaft fixing inner piece (11) having two circular holes (12, 12) each having a rectangular shape through fold lines (a, b, c, d) Therefore, the upper side outer plate (20), which has the outer side plates (22, 22) connected to the left and right, and the reel shaft fixing outer piece (21), and the folding pieces (31, 31), are connected to the left and right sides. A paper box blank made of paperboard, in which a face plate (30), a lower surface outer plate (40) in which left and right side inner plates (42, 42) are connected to the left and right, and a lower inner plate (50) are sequentially connected, Using a printed 230g / m ² mirror-coated Manila paper, in a normal punching process using a punching die, the length, width, and height of the paper box are 64 mm, 104 mm, and 13 mm, respectively, for audio tape cassettes. It shows a state in which a paper box blank is produced.

FIG. 2 is a perspective view showing a state in which a paper box blank is manufactured in the tape cassette paper box of the embodiment. That is, first, insert two reel shaft fixing protrusions (60, 60) made of plastic having a wide flange portion (61) into the two circular holes (12, 12) of this paperboard box blank. Then, the two fold lines (a, d) are mountain-folded, and the upper inner plate (10), the upper outer plate (20), the lower outer plate (40), and the lower inner plate (50). ) And are mechanically pasted together with an appropriate adhesive, and then the four fold lines (b, c, e, e) are mountain-folded and left and right side skins (22, 22 ) And the side inner plate (42, 42) are mechanically pasted with an appropriate adhesive so as to sandwich the left and right folding pieces (31, 31).

Regarding the two reel shaft fixing protrusions (60, 60) made of plastic having the wide flange portion (61) of this embodiment, two reel shaft holes (not shown) of the audio tape cassette are provided. Corresponding to Figure 2, as shown in Fig. 2, two reel shaft fixing protrusions (60, 60) having a common wide flange portion (61) with a diameter of 8 mm and a height of 8 mm are provided with a thickness of 0. A 4 mm polypropylene sheet was pressure-molded and inserted into the two circular holes (12, 12) of the paper box blank described above, and an appropriate adhesive was applied and held.

Next, in the tape cassette paper box of the present embodiment, the fold line (g) is valley-folded and the fold line (f) is mountain-folded, and the reel shaft fixing pieces (11, 21) are pasted with glue. Open and insert a commercially available audio tape cassette (not shown) to accommodate it, and then insert the two reel shaft holes (not shown) of the audio tape cassette into the two reel shaft fixing protrusions (60). , 60), the reel shaft fixing pieces (11, 21) were closed, and the two reel shaft fixing protrusions (60, 60) formed by pressure-molding the polypropylene sheet had an appropriate elasticity. Therefore, the stored audio tape cassette does not rattle, and the reel shaft fixing pieces (11, 21) can hold a stable closed state (the audio tape cassette does not pop out). By further releasing the closed reel shaft fixing pieces (11, 21) with your fingers, I could just take out the audio tape cassette.

[0010]

[Effect of device]

 As described above, in the tape cassette paper box of the present invention, the fold line (g) is valley-folded and the fold line (f) is mountain-folded, and the reel shaft fixing piece pasted with glue ( 11 and 21) are opened and a tape cassette (not shown) is inserted and accommodated, and then two reel shaft holes (not shown) of the tape cassette are set to two reel shaft fixing protrusions (60, 60). When the reel shaft fixing pieces (11, 21) are closed so that the tape cassette accommodated therein, the accommodated tape cassette is loosened due to the appropriate elasticity of the two plastic reel shaft fixing protrusions (60, 60). The reel shaft fixing pieces (11, 21) can hold a stable closed state (the tape cassette does not pop out), and the reel shaft fixing pieces (11, 21) that are not closed. The tape cassette can be easily taken out by releasing () with your finger.

Further, in the tape cassette paper box of the present invention, except for the two reel shaft fixing protrusions (60, 60) made of plastic having a wide flange portion (61), all are made of paperboard. Moreover, it is possible to provide a paper cassette tape cassette paper box that is easy to dispose of waste such as incineration, landfill and recycling, and is environmentally friendly.
