Since the cartridge storage case is made of paper, it is easier to dispose of by incineration compared to plastic, generates less harmful substances by incineration, and can be decomposed and digested into microorganisms in the ground. It can be incorporated into ecosystem systems and has a low environmental impact. Also, since paper is an easily available material, it can be mass-produced at low cost, and since its density is smaller than plastic, a lightweight cartridge storage case can be produced, improving transportability and transport efficiency. , Logistics costs can be reduced. In addition, paper cartridge storage cases are more shock-absorbing than conventional plastic cartridge storage cases, so they can absorb the shocks sufficiently even if they are impacted from the outside and are stored inside. The damaged cartridge will not be damaged.

Hereinafter, examples of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these examples.
The cartridge storage case and the other cartridge storage case have the same structure, and when stacked from above and below, either one can be used as a lid and the other can be worn. The case on the lid side is described as the upper case, and the case on the body side is described as the lower case.

  1 is an exploded perspective view of an upper case and a lower case separated from each other, FIG. 2A is a plan view of the upper case shown in FIG. 1, FIG. 2B is a side view of FIG. FIG. 3 is a view as seen from the arrow A in FIG. 2. FIG. 4 is a schematic cross-sectional view showing a state in which the upper case and the lower case are overlapped. A cartridge storage case (hereinafter also simply referred to as “storage case”) 100 according to an embodiment of the present invention is suitable for storing, for example, a flat cartridge 21 in which a magnetic tape winding reel is installed. Can be used.

  The cartridge 21 is provided with a magnetic tape winding reel (not shown) in such a direction that the axis of the magnetic tape winding reel is in the thickness direction. In this embodiment, the case where the cartridge 21 is a flat body having a square shape in plan view will be described as an example. However, the cartridge may be a flat body having a rectangular shape.

  The storage case 100 shown in FIG. 1 is configured such that a plurality of compartments 27 are formed inside as shown in FIG. 4 by overlapping an upper case 23 and a lower case 25 of the same structure from above and below. It has become. In the present embodiment, a partition portion 47 in the cross direction is formed so as to partition the compartments 27 arranged in four directions into four, and the four compartments 27 are formed. In each compartment 27, as shown in FIG. 1, a plurality of cartridges 21 are juxtaposed in the thickness direction, and a group of cartridges 29 in a block shape can be held. As shown in FIG. 1, the cartridge 21 is preferably arranged with the tape take-out port facing upward so that the weak tape take-out port is on the center side of the compartment 27. More preferably, the compartments 27 are arranged to face each other. In that case, the tape outlet is directed toward the center of the storage case 100, and the tape outlet can be protected from an impact from the outside of the case.

  In this embodiment, one compartment 27 forms substantially the same storage volume as the volume of the cartridge group 29 composed of the five cartridges 21. Therefore, even if the cartridges 21 are randomly packed in the respective compartments 27, there are no partition walls for the individual cartridges 21, so that they can be easily inserted. For example, two to three of the cartridges 21 can be grasped and packed together, and the working efficiency of storage is remarkably improved from the conventional product that is grasped and inserted one by one.

  In this embodiment, each of the upper case 23 and the lower case 25 is made of paper. For this reason, it is possible to mass-produce the upper case 23 and the lower case 25 having a robustness for reliably protecting the cartridge and an excellent shock absorption using a paper material that is inexpensive and easy to handle. In addition, paper is easier to dispose of by incineration compared to plastic, generates less harmful substances by incineration, and can be decomposed and digested into microorganisms in the ground. Therefore, a waste-recovery cycle should be incorporated into the ecosystem. The environmental load is small. Since paper is an easily available material, it can be mass-produced inexpensively, and since paper has a lower density than plastic, a lightweight cartridge storage case can be produced, improving transportability and transport efficiency. , Logistics costs can be reduced.

  As shown in FIG. 5, the storage case 100 integrally formed of paper is provided with a window portion 39 through which the inside of the compartment 27 can be seen. In the present embodiment, a rectangular window 39 is provided at the center of the compartment 27 of the upper case 23. A transparent resin sheet is affixed to the window 39, and the display labels of the cartridges 21 accommodated in the compartment 27 are visible from the outside. Thus, the type of cartridge stored can be confirmed without opening the storage case. The transparent resin sheet of the window part was formed from polylactic acid which is a biodegradable resin. As a result, the entire storage case, including the window, is biodegradable and can be decomposed and digested by microorganisms in the ground. Can reduce the load.

  The storage case 100 is integrally formed of paper having a thickness of 2 mm, so that the minimum structural strength of the compartment for storing a plurality of cartridge groups is economically secured, and the weight of the entire case satisfies the minimum strength. It can be minimized. Moreover, by forming with the above thickness, it is possible to moderately deform when an external force is applied, and it is possible to sufficiently ensure the impact absorbing action on the storage cartridge. That is, if it is thinner than this, the deformation becomes too easy and the impact absorbing effect is reduced. If it is thicker than this, it becomes difficult to deform and the impact force is directly transmitted to the storage cartridge. In the present embodiment, by setting the thickness within the above range, it is possible to form an optimal shock absorbing portion (crushable zone).

  Also, as shown in FIGS. 6 to 8, the paper storage case 10 can be opened and closed when the upper case 23 and the lower case 25 having the same structure are overlapped and engaged from above and below. When the upper case 23 and the lower case 25 are engaged, a plurality of compartments 27 are defined as independent spaces by the partition portions 147 therein. In the present embodiment, the partition portions 147, 147, 147, 147 formed in the cross direction in the upper case and the partition portions 147, 147, 147, 147 formed in the cross direction in the lower case come into contact with each other. The four compartments 27, 27, 27, 27 are divided, and four independent spaces are defined. As a result, even when dust enters one of the plurality of compartments that store the cartridge, the dust does not enter the other compartments, and the dust can be prevented from spreading throughout the storage case.

FIG. 9 is a schematic cross-sectional view of the cartridge storage case 100 in which the upper case 23 and the lower case 25 are overlapped.
In this cartridge storage case 100, the upper case 23 and the lower case 25 are overlapped from above and below, so that the partition portion 147 in the upper case 23 and the partition portion 147 in the lower case 25 come into contact with each other. The compartments 27 and 27 are formed. The wall surface of the compartment formed by the abutment of the partition portion 147 has no gap communicating with the compartment adjacent to the compartment. For this reason, even when dust enters one of the plurality of compartments, it does not enter another adjacent compartment.
In addition, the upper case 23 and the lower case 25 are overlapped so that the contact portion where the partition portion 147 and the partition portion 147 are in contact is flexible and deformed when an impact is applied from the outside ( By bending, the impact is effectively absorbed and the impact force is prevented from being transmitted to the cartridge in the independent space.

  The compartment which is an independent space is formed by engaging the partition part 147 of the upper case and the partition part 147 of the lower case. For example, as shown in FIG. 10, the partition portion 147 a in the upper case has a convex portion 145 and a concave portion 148, and the partition portion 147 b in the lower case that engages with each other has a convex portion 149 and a concave portion 146. Then, when the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146, the convex portion 149 enters the concave portion 148, and both are engaged to form a sealed independent space. A chamber is formed.

As shown in FIG. 11, the partition part 147 a in the upper case has a convex part 145, and the partition part 147 b in the lower case that engages with each other has a concave part 146. When the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146 and engages with each other to form a compartment which is a sealed independent space.
In addition, as shown in FIG. 12, the partition part 147 a in the upper case has a convex part 145 and a convex part 148, and the partition part 147 b in the lower case that engages with each other has a concave part 146 and a concave part 149. Yes. Then, when the upper case and the lower case are overlapped from above and below, the convex portion 145 enters the concave portion 146, the convex portion 148 enters the concave portion 149, and both are engaged to form a sealed independent space. A chamber is formed.

  Here, the upper case and the lower case shown in FIG. 10 are cartridge storage cases having the same structure molded by one mold. The upper case and the lower case shown in FIGS. 11 and 12 are not one type of mold having the same structure, but a mold capable of forming a recess in the partition part of the lower case, and a convex part in the partition part of the upper case. It is formed by using two types of molds, which are possible molds. In addition, you may form a recessed part by a cutting process after that in the partition part of the cartridge storage case of the same structure shape | molded with one metal mold | die, or affixing a convex part.

Moreover, since the partition part 147 is formed from paper, it has a severable part that can separate adjacent independent spaces from each other, and a compartment that is an independent space can be easily separated. For example, in FIG. 10, a perforation 151 is provided between the convex portion 145 and the concave portion 148 (between the concave portion 146 and the convex portion 149). In FIG. 12, a perforation 151 is provided between the convex portion 145 and the convex portion 148 (between the concave portion 146 and the concave portion 149).
By cutting along the perforations 151 of these partition portions, the compartment 27 which is an independent space can be separated while maintaining its independent state, and can be used as a small cartridge storage case which is not bulky. .

  In this embodiment, one compartment 27 forms substantially the same storage volume as the volume of the cartridge group 29 composed of the five cartridges 21. Therefore, even if the cartridges 21 are randomly packed in the respective compartments 27, there are no partition walls for the individual cartridges 21, so that they can be easily inserted. For example, two to three of the cartridges 21 can be grasped and packed together, and the working efficiency of the storage is remarkably improved from the conventional product that is grasped and inserted one by one.

  Thus, the same storage area as that of the conventional storage case 1 shown in FIG. 20 including the flange portion (the type determined by the standard) is included in the amount of the plurality of cartridges 25 stored together in a block shape. Thus, it is possible to secure a surplus area that does not contribute to storage as compared with the case where a plurality of cartridges are stored in a distributed manner. In the storage case 100, this surplus area portion is wider as an impact absorbing portion (so-called crushable zone), that is, wider than the flange portion 11 of the storage case 1 shown in FIG. It is used as an area.

  As shown in FIG. 2A, flanges 31, 31 that are shock absorbing portions extend in the lateral direction on both ends in the axial direction of the magnetic tape winding reels of the upper case 23 and the lower case 25. The flanges 31, 31 are formed with gripping holes 33, 33 which are gripping parts with the central part cut into a square hole shape. In other words, the storage case 100 in which the upper case 23 and the lower case 25 are engaged is carried with one hand (finger) in one of the gripping holes 33 and the other flange 31 facing downward. Can be lifted and lifted. On the other hand, the storage case 100 can be held horizontally by holding the holding holes 33, 33 on both sides with both hands, or can be lifted vertically by holding the holding hole 33 with one hand.

  As described above, when the storage case 100 is slid down from the hand when the storage case 100 is carried with the one gripping hole 33 held with one hand and the other flange 31 positioned downward, the storage case 100 is The lower flange 31 collides with the floor surface. At this time, the flange 31 serving as an impact absorbing portion is deformed by the load of the storage case 100 and the cartridge group 29, and the impact energy is absorbed by the deformation, so that the impact on the stored cartridge 21 is reduced. Yes.

  In general, the cartridge 21 is vulnerable to an impact applied in the reel axial direction. This is because there is a case where the tape pops out on the end surface of the wound tape, and when the tape hits the reel flange due to this tape jumping out, the magnetic tape can be smoothly unwound when it is crushed or bent. This is because it is obstructed, and in the worst case, reading and writing cannot be performed. In the present embodiment, the flange 31 serving as an impact absorbing portion is disposed in the reel axial direction of the cartridge 21 to improve the impact resistance in the reel axial direction which is vulnerable to the impact.

FIG. 13 is an external view of the main part of the storage case showing the first buffer rib 35, the second buffer rib 38, and the third buffer rib 37 provided on the outer wall surface of each compartment.
A first buffer rib 35 is formed on the outer wall surface of each compartment 27 constituting the side surface of the storage case 100 in the thickness direction of the cartridge 21 stored in the compartment 27. In the present embodiment, two first buffer ribs 35 are formed in each compartment 27 so as to protrude in the thickness direction of the cartridge 21. A second buffer rib 38 is formed on the side surface of the storage case 100 perpendicular to the thickness direction of the cartridge 21. In the present embodiment, the second buffer ribs 38 are also formed in a convex shape in each compartment 27. These are simultaneously formed when the upper case and the lower case are formed of a thermoplastic resin.

  When an object collides with the compartment 27 from the outside and an impact is applied in the thickness direction of the cartridge 21, the first buffer rib 35 can be bent to absorb the impact. Similarly, the second buffer rib 38 is bent by itself when an impact in the short direction (width direction) of the cartridge 21 is applied when an object collides with the compartment 27 from the outside. Can be absorbed. That is, the first buffer rib 35 and the second buffer rib 38 form a gap between the outer wall surface of the case and the cartridge 21, and the space serves as a cushioning material to improve impact resistance. ing.

  In addition, a third buffer rib 37 is formed at the corner portion of each compartment 27 so as to surround the ridge line portion of the cartridge 21. Since the third buffer ribs 37 are arranged at the end portions of the first buffer ribs 35 and the second buffer ribs 38, respectively, when the storage case 100 is dropped while the cartridge 21 is stored, Deformation of the cartridge ridge line portion can be effectively prevented.

  The storage case 100 includes an upper case 23 and a lower case 25 having substantially the same structure provided with a convex portion (projection) 41 and a concave portion (concave groove) 43 that are engaged with each other. In the present embodiment, a ridge 41 and a groove 43 are formed in the upper and lower sides around the four compartments 27 so as to be symmetrical with respect to the case center line 45 of FIG. 2A. That is, the upper case 23 and the lower case 25 sandwich the center line 45, and one side is continuously formed with a U-shaped ridge 41, and the other side is continuously formed with a U-shaped groove 43. ing.

  When the upper case 23 and the lower case 25 having the same structure are combined up and down, the ridge 41 enters the groove 43 and both engage. Thereby, the compartment 27 is sealed, and the cartridge 21 can be protected against dust and other harmful substances. That is, one case is used both as a lid and as a body. From this, the storage case 100 in which the compartment 27 that can be opened / closed by the ridge 41 and the groove 43 is formed by using one type of case formed by one mold.

FIG. 14 is an enlarged view of a main part showing a knob piece projecting from the chamfered portion of the storage case flange, and FIG. 15 is a perspective view of a main part showing the mutual positional relationship between the upper and lower case knobs engaged. It is.
The storage case 100 storing the cartridge group 29 may be stored in a cardboard box (not shown) having an inner shape substantially the same as the outer shape. For this reason, chamfered portions 49 having inclined sides of approximately 45 degrees are formed on both sides of the flange 31 in order to improve the ease of taking out from the cardboard box. Thereby, the storage case 100 accommodated in the cardboard box is formed with a triangular hole by the chamfered portion 49 between the inner wall surface of the cardboard box and can be easily taken out by inserting a finger.

  A knob 51 is extended on the periphery of each of the upper case 23 and the lower case 25, that is, on the flange 31. In the present embodiment, the upper case 23 and the lower case 25 are formed in a rectangular outer shape having four corners on the periphery. A chamfered portion 49 is formed at at least one corner of the upper case 23 and the lower case 25 by cutting off the corner with an inclined side. Further, the knob 51 is formed inside a quadrangular region enveloping the four sides of the outer shape of the upper case 23 and the lower case 25. If the knob 51 is extended to the chamfered portion 49, the knob 51 does not protrude from the rectangular case outer shape. For example, the case is accommodated in a cardboard box having the same inner shape as the outer case shape. However, the knob 51 does not interfere with storage.

  In the storage case 100, for the upper case 23 and the lower case 25 that are integrally formed by mutually engaging the ridges 41 and the concave grooves 43, the knobs 51 and 51 provided on the periphery of each case are picked. Thus, an opening force in the separating direction can be easily applied. In other words, when there is no knob 51, the cases can be reliably engaged with each other with a large engagement force that is difficult to release.

  In this embodiment, chamfered portions 49 are formed at four corners. In the present embodiment, the knob 51 is provided on a pair of chamfered portions 49 and 49 that sandwich the center line 45 shown in FIG. 2A. The knobs 51 and 51 are arranged eccentric from the center of the inclined side of the chamfered portion 49. That is, as shown in FIG. 15, the chamfered portion 49 is shifted from the center to one side. For example, in the case of the upper case 23 shown in FIG. 2A, the knob 51 that extends to the upper left chamfer 49 is eccentric from the center of the inclined side obliquely to the lower left and extends to the lower left chamfer 49. The piece 51 is eccentric from the center of the inclined side diagonally downward to the right.

  As shown in FIG. 1, when the upper case 23 and the lower case 25 having the same structure formed by the same mold are formed to form the compartment 27 and are stacked in the vertical direction, the knob 51 is as shown in FIG. In addition, they are not completely overlapped with each other and are arranged in a state of being shifted along the inclined side. Thereby, the engagement between the upper case 23 and the lower case 25 is easily released by separating both the knobs 51 from the upside down direction.

  Further, a step-bending portion 81 having a slightly bent periphery is formed on the outermost periphery of the upper case 23 and the lower case 25. Similar to the ridges 41 and the grooves 43, the step bent portions 81 are formed so that the center line 45 is symmetrical on either side. As a result, when the upper case 23 and the lower case 25 are overlapped, the stepped bent portion 81 covers the other peripheral edge, and the dustproofness is improved.

  Furthermore, large and small square frame portions 53a and 53b that can be loosely fitted to each other are bulged on the outer bottom surface of each compartment 27. Thus, even when the storage case 100 is stacked in the vertical direction, the rectangular frame portions 53a and 53b on the lower surface of the upper storage case 100 are fitted into the square frame portions 53b and 53a on the upper surface of the lower storage case 100, so that the relative Is prevented from collapsing during stacking.

  Further, as shown in FIG. 16, the upper case 23 and the lower case 25 are assembled so that the storage case 100 in which the cartridge group 29 is stored has an impact in the X direction or anti-X direction that is the thickness direction of the cartridge 21 from the outside. Is given to the compartment 27, the first buffer rib 35 of the upper case 23 and the first buffer rib 35 of the lower case 25 bend, respectively, so that the impact in that direction can be absorbed. Further, when an impact in the Z direction or the anti-Z direction, which is the short direction (width direction) of the cartridge 21, is applied to the compartment 27 from the outside, the second buffer rib 38 of the upper case 23 and the second buffer of the lower case 25. Since the ribs 38 bend, the impact in that direction can be absorbed. At this time, when an impact on the compartment 27 is applied to the corner portion, the first buffer rib 35 or the third buffer rib 37 of the upper case 23 and the third buffer rib 37 of the lower case 25 are bent. Absorption of an impact can be promoted because the 2nd buffer rib 38 bends.

  Therefore, according to the cartridge storage case 100, the first buffer rib 35, the second buffer rib 38, and the third buffer rib 37 cause the object to collide with the compartment 27 from the outside or be dropped. In some cases, the quality of the cartridge 21 can be ensured by absorbing the impact and preventing the cartridge housing case 100 from being damaged and the cartridge 21 from being damaged. Further, the plurality of cartridges 21 are dispersed in the same storage area by dividing the plurality of cartridges 21 into a block shape by a partition chamber 27 holding a cartridge group 29 in which the plurality of cartridges 21 are juxtaposed in the thickness direction. Compared to the case of storage, it is possible to secure a surplus area that does not contribute to storage. Then, by using this surplus area portion as an impact absorbing portion (so-called crushable zone), it is possible to absorb an impact when the case is dropped and to improve the impact resistance against the cartridge 21. Further, unlike the conventional case, since it is not necessary to individually store a plurality of cartridges, a plurality of cartridges 21 that are stacked and held in the thickness direction can be collectively stored in the compartment, and efficient storage can be performed in a short time. This makes it possible to greatly improve the storage work efficiency.

  As shown in FIG. 17, the storage case 100 storing the cartridge group 29 is stored in a cardboard box 80 having an inner shape substantially the same as the outer shape. Then, when the storage case 100 is taken out after the cardboard box 80 is opened, it can be easily pulled out by having the convex portion 33 formed on the flange 31. Further, in order to further improve the ease of taking out from the cardboard box 80, chamfered portions 49 having inclined sides of approximately 45 degrees are formed on both sides of the flange 31. Thereby, the storage case 100 accommodated in the cardboard box 80 is formed with a triangular hole by the chamfered portion 49 between the inner wall surface of the cardboard box and can be easily taken out by inserting a finger. ing.

  Therefore, according to the cartridge storage case 100, when the cartridge storage case 100 is taken out from the cardboard box 80, the cartridge storage case 100 can be easily pulled out by the gripping portion including the convex portion 33. In addition, since the four compartments 27 for holding the cartridge group 29 in a block shape by forming a plurality of cartridges juxtaposed in the thickness direction are formed, the conventional cartridge shown in FIG. Compared to the case where a plurality of cartridges 21 are distributed and stored in the same storage area as in the storage case 1, a surplus area that does not contribute to storage can be secured. Then, by utilizing this surplus area portion as a flange for an impact absorbing portion (so-called crushable zone), it is possible to absorb an impact when the case is dropped and to improve the impact resistance against the cartridge 21. Further, unlike the prior art, since it is not necessary to individually store a plurality of cartridges, the plurality of cartridges 21 held in a stacking direction in the thickness direction can be collectively stored in the compartment 27 and can be efficiently stored in a short time. And storage work efficiency can be greatly improved.
