In addition, the cartridge storage case can be carried by grasping the protruding portion that protrudes with one hand, and the working efficiency of storage and handling is greatly improved compared to the conventional case. Further, since the edge portion is not grasped, there is no possibility of damaging the finger. Furthermore, the gripping portion made of the convex portion has sufficient strength because it does not have a hole or notch in the flange, and also has the trouble of positioning at the time of drilling and removing scraps at the time of drilling. There is no such processing operation, and molding can be performed easily and efficiently.

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. 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.

  As shown in FIG. 1, the storage case 100 can be opened and closed by overlapping an upper case 23 and a lower case 25 having the same structure from above and below. By engaging the upper case 23 and the lower case 25, a plurality of compartments 27 are formed therein. 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. As shown in FIG. 1, in each compartment 27, a plurality of cartridges 21 are juxtaposed in the thickness direction to hold a cartridge group 29 in a block shape. 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 greatly improved compared to 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. 15 including the flange portion (the type determined by the standard) is 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. Available as area.

As shown in FIG. 1, flanges 31, 31 that are shock absorbing portions extend in the lateral direction on both ends in the axial direction of magnetic tape winding reels (not shown) of the upper case 23 and the lower case 25. . Each flange 31 is formed with convex portions 33a and 33b extending from the central portion to both end sides. The protrusion 33b of the lower case is formed to protrude in the thickness direction of the flange 31, as shown in FIG. 2B. Thus, when the convex part is formed on either one of the flanges 31 and 31 located at the end in the longitudinal direction (long axis direction) of the storage case 100, the upper case 23 and the lower case 25 are overlapped. As shown in FIG. 4, the storage case includes a gripping portion 33 including a convex portion 33 a with one of both ends protruding upward and a convex portion 33 b with the other protruding downward.
Further, when the convex portion is formed on both of the flanges 31 and 31 located at the end portion in the longitudinal direction of the storage case 100, when the upper case 23 and the lower case 25 are overlapped, as shown in FIG. The storage case has a gripping portion 33 composed of convex portions 33a and 33b protruding upward and downward at both ends.

As shown in FIG. 6, the storage case has a gripping portion 33 composed of convex portions 33 b and 33 b protruding downward from both ends. Note that the upper case 23 and the lower case 25 shown in FIG. 6 are not one type of mold having the same structure, and a mold that can form the convex portion 33b in the lower case and a case in which the convex portion 33a is not formed in the upper case. The mold is formed using two types of molds, a simple mold and the like. In addition, you may form by sticking a convex part later to the cartridge storage case of the same structure shape | molded with one metal mold | die.
Although not shown in the drawings, minute projections for preventing slipping are formed on the surfaces of these convex portions. Moreover, it can also shape | mold so that the surface of a convex part may match the shape of the finger | toe at the time of grasping this convex part. This further facilitates gripping of a gripping portion made of a convex portion.

  The storage case 100 in which the upper case 23 and the lower case 25 are engaged can be carried by holding the grip portion 33 formed of any one of the convex portions with the hand and the other flange 31 facing downward. It is possible and can be lifted. In contrast to this, the storage case 100 holds the holding portions 33, 33 made of convex portions on both sides with both hands and carries them horizontally, or holds the holding portion 33 made of convex portions with one hand and lifts them vertically. You can also

  As described above, when the storage case 100 is slid down from the hand when the storage case 100 is carried with the grip portion 33 formed of one convex portion held with one hand and the other flange 31 positioned downward, the storage case 100 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 moderated. Yes.

7A and 7B are diagrams showing another configuration of the grip portion. In this case, grips 39 and 39 are also formed on the flanges 32 and 32 located at the end in the short direction (short axis direction) of the cartridge storage case. In the present embodiment, a grip portion 39 composed of convex portions 39a and 39b is formed. As described above, when the gripping portion 39 is also formed on the flange of the end portion in the short direction (short axis direction) of the cartridge storage case, the gripping portions 39 on both sides can be gripped with both hands and carried in the horizontal direction. Convenient.
Although not shown in the drawings, the flanges 32 and 32 located at the end in the short direction (short axis direction) of the cartridge storage case extend from the center of the flange to the edge in addition to the convex portions 39a and 39b. It is possible to provide notches or gripping holes, which are excised gripping portions, and this makes it easy to pull out by inserting a finger or the like when taking out the storage case 100 after the cardboard box is opened. Have.
In FIGS. 7A and 7B, the flanges 32, 32 located at the ends in the short direction (short axis direction) have a gripping portion 39, and at the end in the longitudinal direction (long axis direction) of the cartridge storage case. The flanges 31, 31 located are also provided with gripping portions 33 made of convex portions, but the gripping portions 33 made of convex portions in the longitudinal direction can be omitted.

  8, FIG. 9A and FIG. 9B are diagrams showing another configuration of the grip portion. In this case, the convex portions 33a and 33b of the upper case 23 and the lower case 25 constituting the gripping portion 33 are integrally formed so as to be connected to the side wall of the compartment 27, and the upper case 23 and the lower case 25 are overlapped. Then, a gripping portion 33 is formed which includes convex portions 33a and 33b protruding upward and downward at both ends. Since the grip portion 33 is integrated with the case including the compartment, the strength is greatly improved, and even when the weight of the stored item is large, the grip portion 33 can be transported stably. In the present embodiment, the first buffer rib 35 is formed on the side wall of the compartment, and the convex portion 33a is connected to the first buffer rib, and the concave portion is formed between the side wall of the compartment. . For this reason, it is easy to grip the grip portion 33 formed of a convex portion by putting a finger in the concave portion.

  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. 10 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 can absorb the impact by bending itself when an impact in the width direction of the cartridge 21 is applied when an object collides with the compartment 27 from the outside. . 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, water resistance can be obtained, and it is also possible to float on water. Also, the cartridge 21 can be protected against dust, moisture, water, 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. 11 is an enlarged view of a main part representing a knob piece projecting from a chamfered portion of the storage case flange, and FIG. 12 is a perspective view of a main part showing a mutual positional relationship between the upper and lower case engaging pieces. 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. 12, 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 in the compartment 27 and 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.

  FIG. 13 is an enlarged cross-sectional view showing the shapes of the concave and convex portions of the upper case 23 and the lower case 25. As described above, the convex strip 41 and the concave groove 43 can be configured to engage with a higher engagement force by providing the knob 51 and compared with the case where the knob 51 is not provided. Specifically, the opening width W <b> 1 of the groove 43 can be formed slightly smaller than the width W of the ridge 41. Further, the protrusion 41 may have a taper shape with a wide protruding tip width W and a slightly small proximal width W2. In this case, the groove 65 is a tapered groove having a groove bottom width W3 equal to the protruding tip width W of the ridge 41. By forming the ridges 41 and the concave grooves 43 with such a slight taper shape, a high engagement force can be applied while ensuring high sealing performance.

  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. Thereby, when the upper case 23 and the lower case 25 are overlapped, the step bending portion 81 covers the other peripheral edge, so that the dustproof property and the waterproof property are 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 Therefore, it is possible to prevent collapse when stacking.

  Each of the upper case 23 and the lower case 25 is made of an integrally molded product of thermoplastic resin. For this reason, the upper case 23 and the lower case 25 having a robustness that reliably protects the cartridge and an appropriate shock absorption property using a material that is relatively easy to handle can be easily and inexpensively mass-produced. Yes. In this example, a polystyrene resin having an impact strength of 8 J was used.

  Moreover, it is preferable that a thermoplastic resin is what has translucency. Thereby, even when the upper case 23 and the lower case 25 are engaged and the compartment 27 is sealed, the cartridge 21 stored in the compartment 27 can be visually recognized from the outside, and the inside of the compartment 27 is The cartridge storage status can be easily grasped.

  In addition, by forming (vacuum forming) by stretching using a thermoplastic resin sheet having a thickness of 0.5 to 2.0 mm, the minimum structural strength of the compartments accommodating a plurality of cartridge groups is economical. In addition, the weight of the entire case can be minimized while satisfying the minimum strength. Moreover, by forming with the above-mentioned thickness, it is possible to appropriately deform when an external force is applied, and it is possible to optimally secure an 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, an optimal shock absorbing portion (crushable zone) can be formed by setting the sheet thickness of the thermoplastic resin within the above thickness range.

  Therefore, according to the cartridge storage case 100 described above, since the plurality of cartridges 21 are juxtaposed in the thickness direction to form at least one compartment 27 for holding the block-shaped cartridge group 29, the plurality of cartridges 21 are blocked. Compared to the case where a plurality of cartridges 21 are distributed and stored in the same storage area, a surplus area that does not contribute to storage can be secured. Then, by using this surplus area portion as an impact absorbing portion (so-called crushable zone), it is possible to absorb the impact when the case is dropped and to improve the impact resistance with respect to the stored 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.

  Furthermore, according to the cartridge storage case 100 described above, the upper case 23 and the lower case 25, which are integrally formed by mutually engaging the ridges 41 and the groove 43, are provided with tabs provided on the respective peripheral edges. By picking 51, a separating force can be applied, and even if the engagement is hard, the storage case 100 can be easily removed only when it is desired to release the engagement between the ridge 41 and the groove 43 and open it. Can be released. In other words, when there is no knob 51, the cases can be reliably engaged with each other with an engaging force that is difficult to release.

  Further, as shown in FIG. 14, 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 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 rib 38 of the lower case 25 respectively By bending, the impact in that direction can be absorbed. At this time, when an impact on the compartment 27 is applied to the corner portion, in addition to the third buffer rib 37 of the upper case 23 and the third buffer rib 37 of the lower case 25 being bent, the first buffer rib 35 is also bent. Or the 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. 15, 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.

  As mentioned above, although one embodiment of the cartridge storage case of the present invention has been described in detail, the present invention is not limited to the above embodiment, and various modifications may be made without departing from the gist of the present invention.

  When the cartridge storage case of the present invention is taken out from a cardboard box or the like, the cartridge storage case can be easily pulled out by providing a gripping portion made of a convex portion, and the cartridge storage case can be carried with one hand, Since the work efficiency of storage and handling can be greatly improved, it is suitably used as a storage case for collecting and packaging one-reel type magnetic recording tape cartridges, for example.
