Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge storage case for storing a cartridge containing an information recording medium, and more particularly to the prevention of slippage during stacking.

[0002]

2. Description of the Related Art Cartridges such as tape cartridges and disk cartridges containing information recording media such as magnetic recording media and optical recording media are housed in plastic cartridge housing cases and shipped as products.
Various types of cartridge storage cases of this type have been conventionally known. As one of them, a transparent sheet is provided on the surface so that a recorded content or an index sheet on which the recorded content is written can be inserted between the sheet and the surface of the cartridge case.

However, since the cartridge storage case is generally made of plastic, the surface thereof is slippery. When the cartridge storage case is stacked and carried in many stages, the cartridge storage case is dropped due to collapse of the cartridge storage case, and the cartridge storage case is damaged. Further, the stored cartridge may be damaged.

In order to solve this problem, for example, Japanese Patent Application Laid-Open
A cartridge storage case disclosed in Japanese Patent Publication No. 290885 is known. FIG. 3 is a perspective view showing the appearance of the cartridge storage case. Also, FIG.
It is sectional drawing which shows the -B cross section. In FIG. 3, a concave portion 1a having a concave cross section is formed in a part of the upper surface of the cartridge storage case 1, and a transparent sheet 2 is provided on the concave portion 1a. Both outer edges of the sheet 2 in the longitudinal direction are thermally welded to the cartridge storage case 1. Therefore, a gap is formed between the sheet 2 and the concave portion 1a of the cartridge storage case 1. An index sheet or the like is sandwiched in the gap, and the contents of the index sheet or the like are confirmed from outside the cartridge storage case 1. I can do it.

[0005] In the cartridge storage case 1, the surface of the sheet 2 is the same as the surface of the cartridge storage case 1 or a convex surface (the state shown in FIG. 4), and the surface of the sheet 2 is a mirror surface or the like. . By using such a cartridge storage case 1, when the cartridge storage cases 1 are stacked, the overlapping cartridge storage cases 1 are connected to the bottom surface of the upper cartridge storage case 1 and the sheet 2 of the lower cartridge storage case 1. Contact with each other, it is possible to increase the frictional force of the overlapping surfaces, and it is possible to reduce slippage.

[0006]

However, in the above-described conventional cartridge storage case 1, if the outer surface of the sheet 2 protrudes from the surface of the cartridge storage case 1, it is true that
In the overlapping surfaces, the sheet 2 surely comes into contact with the other side, but does not come into contact with the entire surface of the cartridge storage case 1, so that there is a problem that a step is generated when the sheets are stacked and become unstable. For example, cartridge storage case 1
There is a known vending machine in which a plurality of cartridge storage cases 1 are stacked. In this case, since a large number of cartridge storage cases 1 are stacked, the vending machine is unstable and may collapse in the vending machine. There was a problem.

Further, since a step is formed on the surface, the sheet 2 is easily damaged, and there is a problem that the sheet 2 may be damaged when an excessive load is applied. In addition, there is a problem that the visibility of the index sheet and the like stored inside is deteriorated due to the scratch on the sheet 2.

Further, when the surface of the sheet 2 is made to be a mirror surface or the like, it is necessary to perform special processing or use a special material, and there is a problem that the manufacturing cost is increased. Further, when mirror finishing is performed by processing, the thickness of the sheet 2 may vary depending on the degree of processing, and the surface of the sheet 2 may be lower than the surface of the cartridge storage case 1. There is a problem that the effect cannot be exhibited.

Accordingly, an object of the present invention is to provide a cartridge housing case for housing a cartridge containing an information recording medium, which has no variation during manufacture, is low in cost, and prevents slippage during stacking. is there.

[0010]

According to a first aspect of the present invention, there is provided a cartridge storage case for storing a cartridge containing an information recording medium, wherein the cartridge storage case has a recess formed in a part of the surface of the cartridge storage case. To form
A transparent or translucent sheet is formed so that the cartridge storage case and the sheet are substantially flush with each other on the concave portion, the outer edge of the sheet is welded to the cartridge storage case, and a urethane diacrylate is formed on the sheet. Wherein the printing layer is provided with a transparent or translucent ink containing

According to a second aspect of the present invention, in the cartridge storage case according to the first aspect, the printing layer is formed of translucent ink containing a color pigment, and the attribute of the cartridge is displayed by the printing layer. It is characterized by having done.

[0012]

According to the present invention, the sheet is provided on the concave portion of the cartridge storage case so that the sheet is substantially flush with the cartridge storage case. Then, the index sheet or the like can be stored in the gap between the cartridge storage case and the sheet. Further, a printing layer is provided on the sheet with a transparent or translucent ink containing urethane diacrylate.

Accordingly, since the surfaces of the cartridge storage cases are substantially flush with each other, there is no step even when they are stacked. Further, the urethane diacrylate contained in the print layer has an anti-slip effect, and since the print layer on the sheet overlaps with the cartridge storage case on the mating side at the time of lamination, load collapse and the like are less likely to occur when stacked. Furthermore, since the variation in the thickness of the printing layer is so small as to be negligible with respect to the thickness of the sheet, the surface of the cartridge storage case and the surface of the sheet can be made substantially flush with each other without variation in manufacturing. Furthermore, since the printing layer is transparent or translucent, the visibility of the stored index sheet or the like is not hindered. According to the second aspect of the present invention, the attributes of the cartridge are displayed by the print layer without hindering the visibility of the index sheet or the like stored in the sheet, and the function of the stored cartridge can be easily recognized.

[0014]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing an embodiment of a cartridge storage case according to the present invention. FIG. 2 is a sectional view showing an AA section of FIG. 1 and 2, a cartridge storage case 10 (hereinafter, simply referred to as “case 10”) is illustrated.
A concave portion 11 having a concave cross section is formed in a part of the front surface (upper surface and rear surface), and a transparent or translucent sheet 12 is provided on the concave portion 11. The outer edges 12a on both sides in the longitudinal direction of the sheet 12 are
(Heat-welded portion).

With this configuration, the seat 12 and the case 10
Since a gap is formed between the gap 10 and the recessed portion 11, an index sheet or the like can be inserted into the gap to check the content written on the index sheet or the like from outside the case 10. Then, the depth of the concave portion 11 is
, The surface of the sheet 12 and the surface of the case 10 are substantially flush with each other. As a result, the surface of the case 10 becomes flat, and no step occurs even when the cases are stacked. Further, a printing layer 13 is provided on the surface of the sheet 12. In the present embodiment, the print layer 13 is displayed as “C-60” and indicates the grade and the recording time of the cartridge to be stored in the case 10.

When the printing layer 13 is made to be translucent, it contains a color pigment such as calcium carbonate or titanium oxide. When the printing layer 13 is made transparent, no color pigment is required. In addition, a resin such as urethane, epoxy, or ether is added. Further, a solvent is added when a natural drying type ink is used, and a photopolymerization initiator is added when a UV (ultraviolet curing type) ink is used. And in this invention, it contains a urethane diacrylate. The urethane diacrylate is not contained in ordinary printing inks, but is contained in the present invention in order to give the print layer 13 an anti-slip effect.

The above ink is provided on the sheet 12 by printing. As the printing method, any one can be selected from various printing methods such as offset printing, letterpress rotary printing, flexographic printing, and screen printing. After printing, a printing layer 13 is provided on the sheet 12, and projects from the surface of the case 10 by the thickness of the printing layer 13. However, the thickness of the printing layer 13 is so small as to be negligible with respect to the thickness of the sheet 12. Therefore, the surface of the printing layer 13 and the surface of the case 10 are substantially flush with each other.

When the cases 10 are stacked, the bottom surface of the upper case 10 and the printed layer 13 on the sheet 12 of the lower case 10 are in contact between the overlapping cases 10. And since the printing layer 13 contains a urethane-based diacrylate as described above, the friction coefficient of the surface is large, the frictional force of the overlapping surface is high, and the printing layer 13 is hard to slip. Furthermore, since the surface of the printing layer 13 and the surface of the case 10 are substantially flush, even when they are stacked, no level difference occurs, and load collapse and the like can be prevented.

Further, the conventional sheet 2 requires special processing or the like in order to increase the frictional force on the surface. However, in the present invention, since it can be performed only by ordinary printing, the manufacturing cost is reduced. be able to. Further, in the sheet 2 of the conventional example, the thickness varies depending on the degree of processing. However, when the print layer 13 is provided as in the present invention, even if the thickness of the print layer 13 varies, the variation does not occur. Since the range is so small as to be negligible with respect to the thickness of the sheet 12, it is easy to keep the surface substantially flush.

Since the printing layer 13 protrudes from the surface of the case 10 by the thickness thereof, the surface of the printing layer 13 is kept in contact with the case 1 even if the manufacturing depth of the recess 11 varies.
0, and the surface of the printed layer 13 is
It will not be lower than the surface. Further, since the sheet 12 itself does not protrude from the case 10, the sheet 12 is not damaged unlike the conventional example.

[0021]

Next, an embodiment of the present invention will be described. The materials of the case 10 and the sheet 12 were both formed by molding using polypropylene. Here, the sheet 12 is made of the same material to be thermally welded to the case 10. The sheet 12 had a thickness of about 0.15 mm.

As the ink for forming the printing layer 13, an ink having the following composition was used. Color pigment (titanium oxide): 1.0 to 5.0 wt% Urethane diacrylate: 30.0 to 50.0 wt% Ether acrylate: 40.0 to 60.0 wt% Photopolymerization initiator: 4.0 to 8 0.0 wt% Auxiliary agent (antifoaming agent, etc.): 0.5 to 3.0 wt%

In the above composition, the color pigment is translucent and has a blurring effect on printed characters and the like. As a printing method, screen printing was used. The mesh of the printing plate was 360 mesh. The thickness of the printing layer 13 was about 15 μm. The sheet 12 was provided with the printed layer 13 on the surface as described above, cut to fit the dimensions of the case 10, and heat-sealed to the case 10.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in this embodiment,
Although the print layer 13 displays the grade and recording time of the cartridge, the present invention is not limited to this, and other attributes of the cartridge may be displayed. Further, due to the design effect of the case 10, characters other than the attributes of the cartridge are displayed. , A graphic, a symbol or a pattern, for example, a company name may be displayed. When the information display is not performed by the print layer 13, the ink may be made transparent by using the ink containing no color pigment described in the embodiment. Furthermore, in the embodiment, the sheet 12 is provided on the upper surface and the rear surface of the case 10, but may be provided only on the upper surface as shown in FIG.

[0025]

According to the first aspect of the present invention, since the surface of the cartridge storage case and the surface of the sheet are substantially flush with each other, and the printing layer is provided with a transparent or translucent ink having an anti-slip effect, the manufacturing is achieved. No variation in time, low cost,
Do not cause a step when stacking cartridge storage cases,
Load collapse and the like can be suppressed. Further, the visibility of the index sheet or the like stored in the sheet is not hindered. Furthermore, since the sheet does not protrude from the cartridge storage case, damage to the sheet can be prevented, and the visibility of an index sheet or the like stored inside the sheet does not deteriorate even after long-term use.

According to the second aspect of the present invention, since the attributes of the cartridge are displayed without hindering the visibility of the index sheet or the like stored in the sheet, the function of the stored cartridge can be easily recognized. .
