Description

  The present invention relates to a storage case suitable for, for example, transporting a plurality of tape cartridges together.

  Storage medium cartridges (also simply referred to as cartridges) such as disk cartridges and tape cartridges may be exchanged in large quantities for backup of a host computer or the like. In such a case, since it is troublesome to handle the packaging form in which cartridges are individually stored in a case, a bulk type packaging form in which a plurality of cartridges such as 20 cartridges are stored together in one case is preferred. .

  As one of such bulk specification cases, a case by the present inventors has been disclosed (Patent Document 1).

  The case of patent document 1 is comprised by the upper and lower two cases joined mutually. Specifically, the upper case includes a rectangular box-shaped container body whose lower surface is open, and a flange projecting around the opening. The lower case has the same shape and has an upper surface opened. The container body of each case is formed so that a plurality of ribs that support individual cartridges to be stored and prevent contact thereof bulge inward at regular intervals. The four corners of the flange of each case are each formed with a convex portion that protrudes upward.

  After housing a plurality of cartridges in the lower case, the upper and lower cases are brought into contact with each other while fitting the inner and outer surfaces of the convex portions, and the upper and lower cases are integrated by joining the flanges of the cases. The case containing a plurality of cartridges is further stored in a cardboard box and packed, and placed under physical distribution in that state.

JP 2009-286425 A

  Many cases such as Patent Document 1 are generally manufactured by vacuum forming a plastic sheet. The cartridge itself is relatively lightweight, so if it is only a few, the strength is sufficient even in such a case, but if it becomes a large number like the bulk specification, its weight will be considerable, so it will be transported and handled If the case is dropped at times, it may not be able to withstand the weight of the cartridge and the case may be damaged.

  As shown in FIG. 12, in particular, when falling from a ridge portion of the case 100 (for example, a linear edge portion formed by the intersection of the bottom surface and the side surface), the ridge portion becomes linearly large. It breaks and the crack 101 may be formed. If such a large crack 101 is formed in the case, it looks bad and the cartridge T may fall out of the crack 101 during handling. Furthermore, at the same time when the cracks 101 are formed in the case, a drop impact is directly applied to the corner of the cartridge adjacent to the ridge of the case, so that the cartridge may be deformed or damaged.

  Accordingly, an object of the present invention is to provide a storage case that can effectively prevent the ridge portion of the case from being largely broken.

  In order to achieve the above object, the present invention devised the structure of the ridge portion of the storage case.

  Specifically, the storage case of the present invention is a storage case for storing storage medium cartridges in an aligned state, and a pair of storage spaces for storing the cartridges is formed by abutting and joining each other. And at least one of the pair of members includes a rectangular frame-shaped peripheral wall composed of a pair of side walls and a pair of end walls facing each other, and a bottom wall that closes a bottom surface of the peripheral wall A plurality of ribs that are recessed from the outside and protrude inward are formed on the ridge line portion of the case portion including a ridge formed by the bottom wall and the peripheral wall, and the plurality of ribs The first partial ridge line is provided side by side along the ridge, and the plurality of ribs divides the ridge line portion into a plurality of partial ridge line portions including at least a first partial ridge line portion and a second partial ridge line portion. In and said second portion ridgeline portion, a storage case projection amount is different in the ridge.

  In such a storage case, the ridge portion of the storage case (the ridge line portion of the case portion including the ridge formed by the bottom wall and the peripheral wall) is divided into a plurality of partial ridge line portions by a plurality of ribs. , There are portions (first partial ridge line portion and second partial ridge line portion) having different protrusion amounts at the ridge. Accordingly, depending on the amount of protrusion, a portion that easily collides with the floor surface or the like and a portion that does not easily collide are generated at the ridge portion. As a result, even if a part of the ridge portion is broken and a small crack is generated, it is possible to effectively prevent a large portion from being broken and a large linear crack.

  More specifically, when viewed from the direction in which the ridge extends, each of the plurality of partial ridge line portions has a bulged portion having a dominant arc shape at a corner, and the bulged portion of the first partial ridge line portion is Preferably, the second partial ridge line portion is located inside the bulging portion with a gap therebetween.

  Then, the corner can be structurally strengthened. That is, when an external force is applied to the ridge portion, the external force is effectively dispersed and can be prevented from being concentrated locally, so that the strength can be improved. Further, the cartridge can be accommodated without rattling. That is, even if the corner portion of the cartridge is formed at a substantially right angle, the corner portion can be received by the bulging portion, so that the degree of close contact between the cartridge and the case portion increases and the cartridge can be accommodated without rattling.

  Further, as viewed from the direction in which the ridge extends, each of the plurality of partial ridge lines has a semicircular second bulging portion at a connection portion of the bottom wall with the peripheral wall, and the first partial ridge line The second bulging portion of the portion may be positioned inside the second bulging portion of the second partial ridge line portion with a gap therebetween.

  In this case, since the side wall side does not bulge, there is an advantage that molding becomes easy. For example, when extracting a member formed from a mold by vacuum forming, the member is usually extracted in a direction perpendicular to the bottom wall. At this time, since the side wall is not bulged, it is not forced to be pulled out, and can be easily pulled out, resulting in excellent productivity. Since the 2nd bulge part is especially formed in the bottom wall side which is easy to collide, damage can be prevented efficiently. When the cartridge is stored, the second bulging portion does not get in the way, so that rattling of the cartridge can be suppressed.

  In particular, the ridge line portion is composed of the first partial ridge line portion and the second partial ridge line portion, and the first partial ridge line portion and the second partial ridge line portion are alternately provided along the ridge. It is preferable to make it.

  If it does so, since the partial ridgeline part which is easy to break and the partial ridgeline part which is hard to break are arranged with good balance, it excels in the intensity as the whole ridgeline part. Moreover, even if it is damaged, the ridge line portion that is easily damaged is intermittently damaged, so that only small cracks can be generated, and the cartridge can be reliably prevented from falling off during handling.

  For example, each of the pair of members is formed of a member having the same shape having the case portion, and the plurality of ribs are provided on each of the pair of ridge lines facing each other across the bottom wall on the pair of side walls. What is necessary is just to make it arrange | position so that the said 1st partial ridgeline part of one ridgeline part may oppose the said 2nd partial ridgeline part of the other ridgeline part in a pair of said ridgeline part.

  If it does so, since each of a pair of member can be shared, it is excellent in productivity and handling becomes easy. In addition, since the storage cases can be stacked so that the partial ridge lines with large protrusions do not face each other, the gap between the storage cases can be reduced when a plurality of storage cases are stacked.

  In this case, a fitting portion is formed on the outer surface of the bottom wall, and the two bottom walls are brought into contact with each other by contacting the outer surfaces of the two bottom walls. In the state where the fitting portion can be fitted and the two fitting portions are fitted, the amount of protrusion of the first partial ridge line portion from the outer surface is larger than the distance between the two bottom walls. The total amount of the second partial ridge line portion and the protruding amount from the outer surface can be set smaller.

  Then, when stacking multiple storage cases, the ridge lines of each storage case do not come in contact, so that the fitting parts can be firmly fitted, and the ridge lines of the two storage cases are also stacked after stacking. Since contact between each other can be avoided with certainty, for example, abrasion and crushing due to rubbing can be effectively prevented, and convenience and durability are excellent.

  As described above, according to the storage case of the present invention, it is possible to effectively prevent the ridge portion of the storage case from being largely broken.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the following description is merely illustrative in nature and does not limit the present invention, its application, or its use.

  In FIG. 1, a part (half-body case 2) of the storage case 1 of this embodiment is shown. The storage case 1 is composed of a pair of half-body cases 2 and 2, each of which is a member having the same shape. By using the same shape member for each half case 2, 2, it is excellent in productivity and easy to handle. In the storage space formed by joining the half cases 2 and 2 up and down, six tape cartridges T, T,... Can be stored in an aligned state.

  Each half-body case 2 is integrally formed by so-called vacuum forming, for example, by heating and softening a sheet of synthetic resin such as PET or PP, and then forming it in close contact with a mold having a predetermined shape by vacuuming. . PET (polyethylene terephthalate) excellent in transparency is used for the material of each half-body case 2 of the present embodiment. By doing so, the tape cartridge T stored from outside the storage case 1 can be clearly seen. For example, when a barcode is attached to the tape cartridge T, the barcode can be read through the storage case 1. Because it is possible, it is excellent in convenience.

  As shown also in FIG. 2, each half-body case 2 protrudes outward from the edge of the opening of the case part 10 and the case part 10 having a rectangular (rectangular) box shape having an opening on one surface. And a flange portion 30.

  Engaging portions 31a, 31a, 31b, and 31b are formed at the four corner portions of the flange portion 30, respectively. Specifically, convex portions 31a and 31a projecting from the opening-side surface are formed at one diagonal position of the flange portion 30, and projecting portions 31a and 31a projecting in opposite directions from the other diagonal position, respectively. The fitting recesses 31b and 31b are formed. Therefore, by abutting the pair of half-body cases 2 and 2 from the opening side, the respective concave portions 31a and the respective convex portions 31b can be fitted and the flange portions 30 can be brought into close contact with each other. Thus, a substantially sealed storage case 1 is obtained by joining the two half cases 2 and 2 together.

  The case portion 10 includes a rectangular frame-shaped peripheral wall 11 and a rectangular plate-shaped bottom wall 12 that closes the bottom surface of the rectangular peripheral wall 11. Specifically, the peripheral wall 11 is formed integrally with the bottom wall 12, and a pair of side walls 11 a and 11 a (long side) facing each other, and a pair of end walls facing each other perpendicular to the side walls 11 a and 11 a. 11b, 11b (short side).

  A plurality of bottom ribs 13 (seven in this embodiment) are formed at the center of the bottom wall 12 at regular intervals along the long side. Each bottom rib 13 has a short bowl shape, and is formed such that the bottom wall 12 protrudes inside the case portion 10 and extends along the short side. A part of each of the bottom ribs 13 at both ends is formed integrally with the end wall 11b.

  First and second fitting ribs 14 and 15 (fitting portions) are arranged side by side on the bottom wall 12 in order to abut the two half-body cases 2 and 2 from the bottom wall 12 side so as to be detachable. Is formed. These fitting ribs 14 and 15 are formed in a quadrangular ring shape in a plan view, and are recessed from the inside of the bottom wall 12 and project outward in a band shape. The first fitting rib 14 is formed to be slightly larger than the second fitting rib 15 in plan view. Each fitting rib 14 and 15 is arrange | positioned in the point-symmetrical position with respect to the center of a bottom face. With the fitting ribs 14 and 15 facing each other, the fitting ribs 14 and 15 are fitted together by abutting the outer surfaces of the bottom walls 12 and 12 of the two half-body cases 2 and 2. Thereby, the storage case 1 can be piled up and down, connecting (refer FIG. 6).

  Seven vertical ribs 16 are formed in the portion extending from the bottom wall 12 to both side walls 11a and 11a inside the case portion 10, respectively. Specifically, a portion (ridge line portion) along the ridge of the case portion 10 including the ridge 17 (line segment or edge formed by the intersection of the bottom wall 12 and the side wall 11a) formed by the bottom wall 12 and the side wall 11a. 20), a plurality of vertical ribs 16 that are recessed from the outside and project inward are formed. Each vertical rib 16 is formed so that the inner surface of each side wall 11a extends from the bottom wall 12 toward the opening, and is gradually narrowed toward the tip side. Each vertical rib 16 is formed with the same width as the bottom rib 13.

  The vertical ribs 16 are provided along the ridges 17 at the same intervals as the bottom ribs 13 and face each other across the bottom wall 12. The pair of opposing vertical ribs 16 and 16 and the bottom rib 13 positioned therebetween are aligned in a straight line (also referred to as a rib row). The interval between the rib rows is set in accordance with the width dimension of the tape cartridge T, and the tape cartridge T can be inserted and supported one by one between two adjacent rib rows. By these rib rows, the plurality of tape cartridges T are supported in an aligned state without contacting each other, and the case portion 10 is structurally reinforced.

  The ridge line part 20 on the side wall 11a side in the case part 10 is divided into a plurality of (six in this embodiment) parts (partial ridge line parts) by the plurality of vertical ribs 16.

  Conventionally, the corners (ridges and corners) corresponding to these partial ridge lines are formed substantially at right angles in accordance with the corner shape of the tape cartridge T, and these ridges are positioned on the same straight line. Therefore, there was a case where it was greatly broken linearly along the edge (see FIG. 12). Therefore, in the present embodiment, the shape of the ridge line portion is devised so as to prevent such breakage.

  That is, as shown in FIGS. 3 and 4, the first partial ridge line portions 21 and the second partial ridge line portions 22 having different protrusion amounts of the ridge 17 are provided alternately. Specifically, the portion of the ridge 17 of the second partial ridge line portion 22 protrudes more outward than the portion of the ridge 17 of the first partial ridge line portion 21, and the first partial ridge line portion 21 and the second partial ridge line portion 22 Are arranged alternately along the ridges 17. One partial ridge line portion 21 (22) is adjacent to the other partial ridge line portion 22 (21). In addition, the effect by this is mentioned later.

  As shown in FIG. 4, when viewed from the direction in which the ridge 17 extends, each of the partial ridge line portions 21, 22 of the present embodiment has a bulged portion 23 having a superior arc shape at the corner. Most of these bulging portions 23 are located outside the contour lines of the bottom wall 12 and the side wall 11a in each partial ridge line portion 20. And the bulging part 23 of the 1st partial ridgeline part 21 is located inside the bulging part 23 of the 2nd partial ridgeline part 22 across the clearance gap S1. That is, the bulging portion 23 of the first partial ridge line portion 21 is formed smaller than the bulging portion 23 of the second partial ridge line portion 22.

  FIG. 5 is a schematic sectional view thereof. As shown in the figure, by providing the bulging portion 23, the tape cartridge T can be accommodated without rattling. That is, even if the corner portion of the tape cartridge T is formed at a substantially right angle, the corner portion can be received by the bulging portion 23. Therefore, the outer surface of the tape cartridge T is supported by the bottom wall 12 and the side wall 11a of the case portion 10. Can be received without gaps. Accordingly, the degree of close contact between the tape cartridge T and the case portion 10 is increased during storage, so that the tape cartridge T can be stored without rattling, and an extra load can be prevented from being applied to the corner.

  Furthermore, the corners can be structurally strengthened by forming them in a dominant arc shape. That is, when an external force is applied to the portion of the ridge 17, the external force is effectively dispersed and can be prevented from being concentrated locally, so that the strength can be improved. That is, cushioning properties can be obtained.

  As shown in FIG. 2, in the pair of ridge line portions 20, 20 facing each other with the bottom wall 12 interposed therebetween, the first partial ridge line portion 21 of one ridge line portion 20 is the second portion of the other ridge line portion 20. It is preferable to arrange so as to face the ridge line portion 22. Then, when stacking the storage cases 1, for example, assuming that the two storage cases 1 are joined by reversing the long side of one storage case 1 with the short sides of the storage case 1 in the same direction. The first partial ridge line portion 21 of one storage case 1 faces the second partial ridge line portion 22 of the other storage case 1 in the vertical direction, so that the second partial ridge line portions 22 having a large protruding amount do not face each other. Accordingly, when the storage cases 1 are stacked, the gap between the storage cases 1 can be reduced.

  In the present embodiment, since the above-described fitting ribs 14 and 15 are provided, the two storage cases 1 and 1 are, for example, one storage case 1 in a state where the short side of the storage case 1 is reversed. The two storage cases 1 are joined by reversing the long side.

  Therefore, in the storage case 1 of the present embodiment, the first partial ridge line portion 21 and the second partial ridge line portion 22 are alternately arranged in each of the pair of ridge line portions 20 and 20 facing each other with the bottom wall 12 interposed therebetween. The partial ridge line portions arranged at both ends are arranged so as to become the first partial ridge line portion 21 and the second partial ridge line portion 22, respectively. By doing so, when the storage cases 1 are stacked in the same manner as described above, the first partial ridge line portion 21 of one storage case 1 faces the second partial ridge line portion 22 of the other storage case 1 in the vertical direction. The large second partial ridge line portions 22 do not have to face each other.

  FIG. 6 shows a state in which two storage cases 1 are stacked and connected. As shown in the figure, since the first partial ridge line portion 21 of one storage case 1 faces the second partial ridge line portion 22 of the other storage case 1 in the vertical direction, the gap between the storage cases 1 can be reduced.

  At this time, the protrusion amount L2 from the outer surface of the bottom wall 12 in the first partial ridge line portion 21 and the second partial ridge line portion 22 than the distance L1 between the bottom walls 12 and 12 of the two storage cases 1 facing each other. It is preferable to set so that the total amount with the protrusion amount L3 from the outer surface of the bottom wall 12 becomes smaller. The protruding amount is the protruding amount in the direction orthogonal to the bottom wall 12. Then, the fitting ribs 14 and 15 can be firmly fitted, and the ridge line portions 20 of the two storage cases 1, more specifically, the first partial ridge line portion 21 of the one storage case 1 and the other Since the contact with the second partial ridge line portion 22 of the storage case 1 can be avoided with certainty, for example, abrasion or crushing due to friction can be effectively prevented.

  When the storage case 1 is used, the tape cartridges T, T,... Are inserted into one half case 2 and then the other half case 2 is joined so as to cover it. As shown in FIG. 7, the storage case 1 storing a plurality of tape cartridges T, T,... Is stored and packed in a cardboard box 3 which is an outer packaging material, and placed under physical distribution.

  As shown in FIG. 8, in the process of physical distribution, for example, the cardboard box 3 may fall from the ridge side to the floor surface F due to the collapse of cargo or careless handling. In that case, since the cardboard box 3 is easily deformed, most of the impact of the collision acts on the packaged storage case 1.

  In the case of the conventional storage case 1, since the protruding amount of the part corresponding to the partial ridge line part 20 is the same, when these collide with the floor or the like in the same way, a large linear crack may occur. there were.

  On the other hand, in the storage case 1 of the present embodiment, since the protruding amount of the partial ridge line portion is different, the partial ridge line portion (second partial ridge line portion 22) that easily collides with the floor surface etc. F due to the size of the protruding amount. A partial ridge line portion (first partial ridge line portion 21) that is difficult to collide is generated. As a result, even though a part of the ridge line part 20 (second partial ridge line part 22) may be damaged, most (first partial ridge line part 21 and second partial ridge line part 22) are damaged and linear. Large cracks can be prevented.

  In addition, since each ridge line portion 20 is provided with a bulging portion 23 and structurally strengthened, the damage itself is less likely to occur.

  In particular, by providing the first partial ridge line portion 21 and the second partial ridge line portion 22 alternately, the first partial ridge line portion 21 (22) is adjacent to the other partial ridge line portion 22 (21). The partial ridge line portion 21 is more difficult to break, and even if the second partial ridge line portion 22 is broken, only a small crack can be generated, so that the tape cartridge T can be reliably prevented from falling off during handling.

(Modification)
9 and 10 show a modified example of the storage case 1. In this storage case 1, two half-body cases 2 and 2 of the previous embodiment are connected and integrated at one end on the long side to form one half-body case (second half-body case 2A). . In this case, a total of 12 tape cartridges T can be accommodated in two rows. If the number of half-body cases 2 to be connected is increased, the number of tape cartridges that can be stored can be increased.

  In this case, since there is no possibility that a large external force acts on the two ridge line portions 20a and 20a facing each other between the two adjacent case portions 10 and 10 due to the collision, the protruding amount as in the conventional storage case May be the same.

  Further, the housing portion of the tape cartridge T may be increased by extending the case portion 10 in the direction in which the ridge 17 extends.

  In FIG. 11, the modification regarding the shape of the ridgeline part 20 is shown.

  In (a) of the figure, the bulging portion 23 is formed only on the bottom wall 12 side (second bulging portion 23A). Specifically, when viewed from the direction in which the ridge 17 extends, a semicircular second bulging portion 23A that bulges outward is formed at the connecting portion of the partial ridge line portions 21 and 22 with the side wall 11a of the bottom wall 12. Forming. And the 2nd bulge part 23A of the 1st partial ridgeline part 21 is located inside the 2nd bulge part 23A of the 2nd partial ridgeline part 22 across the clearance gap S2.

  In this case, since the side wall 11a side does not bulge, there is an advantage that molding becomes easy. That is, in vacuum forming, when the half-body case 2 formed from the mold is extracted, it is normally extracted in a direction perpendicular to the bottom wall 12, so that it is not excessively extracted and can be easily extracted, resulting in excellent productivity. .

  In particular, since the second bulging portion 23A is formed on the bottom wall 12 side that is likely to collide, breakage can be efficiently prevented. Shaking of the stored tape cartridge T can also be suppressed.

  In (b) of the same figure, the shape of the corner seen from the direction in which the ridge 17 extends is formed substantially perpendicular to the ridge line portion 20 of the conventional storage case 1. Although not shown, the corners may be end-face treated to form an inferior arc-shaped radius. However, the corner part in the 1st partial ridgeline part 21 is comprised so that it may be located inside the corner part in the 2nd partial ridgeline part 22 across the clearance gap.

  Even in this case, since the ease of collision can be made different between the first partial ridge line portion 21 and the second partial ridge line portion 22, the occurrence of large cracks can be suppressed.

  In addition, the storage case 1 concerning this invention is not limited to the said embodiment and modification, The other various structures are included.

  For example, the storage case 1 may be composed of a container-like member having the case portion 10 and a lid-like member. The plurality of partial ridge line portions 20 may include three or more partial ridge line portions having different protrusion amounts. The arrangement is not necessarily alternating, and can be set in various ways. The shape, number, arrangement, and the like of the fitting ribs can be appropriately modified as necessary. The tape cartridges T do not necessarily have to be stored separately, and may be stored for every several tape cartridges T, for example.
