[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-33070 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is a problem in that it is difficult to remove the packaged items stored in the packaging box from the bottom of the one-touch bottom type.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a printing cassette storage unit that allows printing cassettes to be easily removed from the bottom of the storage box with a one-touch bottom. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a printing cassette storage unit including a printing cassette and a storage box that stores the printing cassette, wherein the storage box has a first wall and a second wall that extend so as to intersect a first direction and are arranged side by side in the first direction, and a peripheral wall that extends from a periphery of the first wall to a periphery of the second wall, the printing cassette is arranged in a space surrounded by the first wall, the second wall, and the peripheral wall, the peripheral wall includes a first peripheral wall and a second peripheral wall that extend so as to intersect a second direction that is orthogonal to the first direction and are arranged side by side in the second direction, and a third peripheral wall and a fourth peripheral wall that extend so as to intersect a third direction that is orthogonal to the first direction and the second direction and are arranged side by side in the third direction, and the first wall is a first specific direction in the first direction that is from the second wall toward the first wall. a first flap connected to a first connecting end which is an edge of the second peripheral wall in the first specific direction, a second flap connected to the second connecting end which is an edge of the second peripheral wall in the first specific direction, a third flap connected to a third connecting end which is an edge of the third peripheral wall in the first specific direction, and a fourth flap connected to a fourth connecting end which is an edge of the fourth peripheral wall in the first specific direction, wherein the first flap and the third flap are adhered to each other by a first adhesive portion, and the second flap and the fourth flap are adhered to each other by a second adhesive portion, so that when the peripheral walls are folded into a three-dimensional rectangular tube shape, a one-touch bottom is formed with the first wall assembled thereto, and the storage box has a first separation portion for separating the connection between the first peripheral wall and the third peripheral wall via the first flap, the third flap, and the first adhesive portion.

[0007] By separating the first separation portion, the portion of the third peripheral wall connected to the third flap via the third connecting end that is separated by the first separation portion remains adhered to the first flap via the first adhesive portion. Because the first flap is connected to the first peripheral wall via the first connecting end, the first peripheral wall and the third peripheral wall are separated. This allows the user to open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box.

[0008] In this aspect, the first separation portion may be a tearable tear line formed on the third connecting end or the third peripheral wall, and tearing the first separation portion may separate the third flap from the third peripheral wall. By tearing the first separation portion, a user can open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box.

[0009] In this aspect, the storage box has a second separation portion for separating the connection between the second peripheral wall and the fourth peripheral wall via the second flap, the fourth flap, and the second adhesive portion, and the second separation portion may be a tearable tear line formed on the fourth connecting end or the fourth peripheral wall, and tearing the second separation portion separates the fourth flap from the fourth peripheral wall. A first separation portion and a second separation portion are formed on each of the third peripheral wall and the fourth peripheral wall, which face each other in a third direction, and tearing the first separation portion separates the first peripheral wall from the third peripheral wall, and tearing the second separation portion separates the second peripheral wall from the fourth peripheral wall. Thus, by tearing the first separation portion and the second separation portion, a user can completely open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box.

[0010] In this aspect, the storage box may have a second separation portion for separating the connection between the second peripheral wall and the fourth peripheral wall via the second flap, the fourth flap, and the second adhesive portion, the second separation portion being a tearable tear line formed on the second connecting end or the second peripheral wall, and the second flap may be separated from the second peripheral wall by tearing the second separation portion. A first separation portion and a second separation portion are formed on two adjacent peripheral walls, the third peripheral wall and the second peripheral wall, respectively, and the first peripheral wall and the third peripheral wall can be separated by tearing the first separation portion, and the second peripheral wall and the fourth peripheral wall can be separated by tearing the second separation portion. Thus, by tearing the first separation portion and the second separation portion, the first wall constituting the one-touch bottom of the printing cassette storage unit can be completely opened, allowing the printing cassette to be removed from the storage box. Furthermore, the first detachable portion and the second detachable portion can be seen at once from the corners of the third peripheral wall, the second peripheral wall, and the first wall, so the user can break the first detachable portion and the second detachable portion to open the first wall without changing the orientation of the storage box.

[0011] In this aspect, the first separation portion and the second separation portion may be connected across a fifth connecting end, which is an edge connecting the third peripheral wall and the fourth peripheral wall. Because the first separation portion and the second separation portion are connected across the fifth connecting end, the first separation portion and the second separation portion can be torn together as a single separation portion. This allows a user to open the first wall that constitutes the one-touch bottom with a single separation operation and remove the printing cassette from the storage box.

[0012] In this aspect, the first separation portion may be formed on the third peripheral wall, and the separation portion, which is part of the third peripheral wall and is separated together with the third flap when the first separation portion is broken, may have an asymmetric shape in the second direction, and the area of ​​a portion closer to the first peripheral wall in the second direction that is the target of separation from the third peripheral wall may be smaller than the area of ​​a portion farther away.When a user breaks the first separation portion along the shape of the non-separable portion, the printing cassette storage box can encourage the direction of force used to break the third peripheral wall through the first separation portion to be in an appropriate direction.This allows the user to easily open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box.

[0013] In this aspect, the peripheral wall may be formed by folding a single sheet into a rectangular tube shape, with one edge of the sheet having a bonding portion for bonding to the other edge, and the bonding portion may be formed in a position in the first direction away from the formation position of the first separation portion in the opposite direction to the first specific direction. The formation position of the first separation portion does not overlap with the bonding portion. Therefore, the adhesive applied to the bonding portion does not hinder the first separation portion from being separated, and the user can easily open the first wall and remove the printing cassette from the storage box.

[0014] In this aspect, the printing cassette includes a case that accommodates printing tape, the case having an outer surface that has a recessed portion that forms a recess in a rectangular parallelepiped shape, and the first separation portion may be formed in a position on the peripheral wall that overlaps with the recessed portion when the printing cassette is placed in the space. The first separation portion is formed in a position that overlaps with the recessed portion of the case of the printing cassette. Therefore, a user can break the first separation portion by pushing it toward the recessed portion, thereby easily opening the first wall and removing the printing cassette from the storage box.

[0015] In this aspect, the case may have an outlet for discharging the printing tape stored inside the case to the outside of the case, and the printing cassette may be placed in the space of the storage box with the outlet facing the second wall of the storage box. Because the outlet is located on the second wall side opposite the first wall, it is difficult for a user to touch the printing tape when removing the printing cassette from the storage box.

[0016] In this aspect, the first separation portion may be a tearable tear line formed in the first flap, and tearing the first separation portion may separate the third flap from the first flap. By separating the first separation portion, the first flap connected to the first peripheral wall and the third flap connected to the third peripheral wall are separated, thereby releasing the connection between the first peripheral wall, the third peripheral wall, and the first wall. This allows a user to open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box.

[0017] In this aspect, the first flap may have a first starting point portion, which serves as a starting point for breaking the first separation portion, on an edge parallel to the first connecting end. By providing the first starting point portion on an edge parallel to the first connecting end, it is possible to ensure the connection length between the first starting point portion and the first flap and increase strength.

[0018] In this aspect, the first flap may have a first starting point portion, which serves as a starting point for breaking the first separation portion, on an edge non-parallel to the first connecting end. As the length of the storage box in the second direction increases, the length of the edge of the first flap parallel to the first connecting end becomes relatively shorter and the length of the non-parallel edge becomes relatively longer. In this case, by providing the first starting point portion on the edge non-parallel to the first connecting end, the connection length between the first starting point and the first flap can be ensured and strength can be increased.

[0019] In this aspect, the storage box may have a second separation portion for separating the second peripheral wall and the fourth peripheral wall from each other via the second flap, the fourth flap, and the second adhesive portion, the second separation portion being a tearable tear line formed on the second flap, and the fourth flap may have a second starting point portion that serves as a starting point for tearing the first separation portion. The first flap and the second flap may each have a first separation portion and a second separation portion, and the first peripheral wall and the third peripheral wall may be separated from each other by tearing the first separation portion, and the second peripheral wall and the fourth peripheral wall may be separated from each other by tearing the second separation portion. Thus, a user can completely open the first wall that constitutes the one-touch bottom and remove the printing cassette from the storage box by tearing the first separation portion and the second separation portion.

[0020] In this aspect, the first and second starting points may be formed on the first wall. By forming the first and second starting points on the first wall, when multiple printing cassette housings are packed for transport, it is possible to prevent the first or second starting point from getting caught on an adjacent printing cassette housing, thereby preventing the first or second separation portion from breaking.

[0021] In this aspect, the first flap may have a first fold line between the region where it is adhered to the third flap via the first adhesive portion and the region where it is connected to the first peripheral wall, and the second flap may have a second fold line between the region where it is adhered to the fourth flap via the second adhesive portion and the region where it is connected to the first peripheral wall, and the first separation portion may be formed at the first fold line and the second separation portion may be formed at the second fold line. By forming the first separation portion at the first fold line and the second separation portion at the second fold line, a user can easily tear the first separation portion and the second separation portion and remove the printing cassette from the storage box.

[0022] In this aspect, the printing cassette may include a case that contains a printing tape, the case having an outlet for discharging the printing tape contained inside the case to the outside of the case, and the printing cassette may be placed in the space of the storage box with the outlet facing the second wall of the storage box. Because the outlet is located on the second wall side opposite the first wall, it is difficult for a user to touch the printing tape when removing the printing cassette from the storage box.

The upper end 612 of the front wall 61, the upper end 622 of the back wall 62, the upper end 632 of the left wall 63, and the upper end 642 of the right wall 64 form the peripheral edge 50 of the top wall 5 (see FIG. 1).

[0030] A space 7 is formed inside the box body 2. The space 7 is surrounded by a bottom wall 4, a top wall 5, and peripheral walls 6 (a front wall 61, a back wall 62, a left wall 63, and a right wall 64). A tape cassette 8 is placed in the space 7 with a lower wall 85 (described below) facing the bottom wall 4 from above.

[0031] The header 3 is provided on the box body 2. The header 3 is wall-shaped and includes a header piece 31 and a header piece 32. The header piece 31 is connected to an upper end 622 of the back wall 62 and extends upward from the upper end 622 of the back wall 62. In FIG. 2, the upper end 622 of the back wall 62 is indicated by an imaginary line V0. The header piece 32 is folded back forward from the upper end 311 of the header piece 31 and extends downward. The lower end 321 of the header piece 32 is located at the position of the top wall 5 in the vertical direction and is connected to a female flap 52 (see FIG. 3) described below.

[0032] A hole 30 is provided in the header 3. The hole 30 has an isosceles triangular shape when viewed from the front, and is located in the left-right center of the header 3. The hole 30 penetrates the header pieces 31, 32 in the front-rear direction. Therefore, the hole 30 penetrates the header 3 in the front-rear direction. For example, in a distribution market for storage boxes 1A, the storage box 1A may be inserted through the hole 30 onto a rod for hanging and displaying products, and the storage box 1A may be hung and displayed.

[0033] The detailed structure of the top wall 5 will be described with reference to Figures 1, 3, and 5. The top wall 5 includes a male flap 51, a female flap 52, a left flap 53, and a right flap 54. The male flap 51 is connected to the upper end 612 of the front wall 61 and has a male main body portion 515 and an insertion portion 55. The male main body portion 515 extends rearward from the upper end 612 of the front wall 61. The male main body portion 515 has a rectangular shape that is longer in the left-right direction than in the front-to-back direction. The length of the male main body portion 515 in the front-to-back direction is approximately the same as the distance between the front wall 61 and the rear wall 62 in the front-to-back direction. The rear end 511 of the male main body portion 515 is located near the front of the rear wall 62 and extends in the left-to-right direction. The male main body portion 515 has an opening 513 that penetrates the male main body portion 515 in the vertical direction.

The left flap 53 and the right flap 54 are each rectangular and longer in the left-right direction than in the front-to-back direction, and are bilaterally symmetrical to each other. A cutout 531 is provided in the left flap 53. The cutout 531 cuts out the rear end of the left flap 53 toward the front. A cutout 541 is provided in the right flap 54. The cutout 541 cuts out the rear end of the right flap 54 toward the front. The left-right length of each of the left flap 53 and the right flap 54 is approximately the same as the left-right distance between the left wall 63 and the right wall 64. In the first embodiment, the left flap 53 overlaps the right flap 54.

[0038] Hereinafter, the layer constituted by the male flaps 51 will be referred to as the "male flap layer 501." In the first embodiment, in a plan view, the outer shape of the male flap layer 501 is determined by the outer shape of the male main body portion 515. The layer constituted by the female flaps 52 will be referred to as the "female flap layer 502." In the first embodiment, in a plan view, the outer shape of the female flap layer 502 is determined by the outer shape of the female flaps 52. The layer constituted by the left flap 53 and the right flap 54 will be referred to as the "side flap layer 503." In the first embodiment, in a plan view, the outer shape of the side flap layer 503 is determined by the outer shapes of the left flap 53 and the right flap 54.

[0039] In the top wall 5, the male flap layer 501, female flap layer 502, and side flap layer 503 are stacked in the following order from bottom to top: female flap layer 502, side flap layer 503, male flap layer 501. The insertion portion 55 is positioned inside the female flap 52 via the insertion opening 521. The left flap 53 and the right flap 54 are provided with cutouts 531 and 541, respectively, so that the side flap layer 503 does not overlap with the insertion opening 521 in a plan view.

[0040] The detailed structures of the peripheral wall 6 and the bottom wall 4 will be described with reference to Figures 2, 4, and 5. The left wall 63 has a perforation 623 and a cut line 625. The perforation 623 is formed in the lower part of the left wall 63, extends upward in an arc from the left end of the lower end 631 of the left wall 63, and then extends in a substantially linear fashion to the right end of the left wall 63. The cut line 625 is a cutting line cut in the vertical direction along the right end of the left wall 63 from the right end of the perforation 623 to the right end of the lower end 631 of the left wall 63, leaving both ends. The right wall 64 has a perforation 624. The perforation 624 is formed in the lower part of the right wall 64, extends upward in an arc from the left end of the lower end 641 of the right wall 64, and then extends in a substantially linear fashion to the right end of the right wall 64. In the portion from the right end of the perforation 624 to the right end of the lower end 641 of the right wall 64, the right end of the right wall 64 is not connected to the left end of the spine wall 62. Hereinafter, the area of ​​the left wall 63 surrounded by the perforation 623, the cut line 625, and the lower end 631 will be referred to as the "starting region R11." The area of ​​the right wall 64 surrounded by the perforation 624 and the right end and lower end 641 of the right wall 64 will be referred to as the "starting region R12." When opening the storage box 1A from the bottom wall 4 side, a user pushes the starting region R11 into the box body 2 and tears the perforation 623 and the cut line 625, thereby separating the spine wall 62, which is connected to the starting region R11 via the left flap 43, the adhesive portion 452, and the back flap 42, from the left wall 63. Similarly, by pushing the starting region R12 into the box body 2 and breaking the perforation 624, the front wall 61 connected to the starting region R12 via the right flap 44, adhesive portion 451 and front flap 41 is separated from the right wall 64.

[0041] The bottom wall 4 is a so-called one-touch bottom, and includes a front flap 41, a rear flap 42, a left flap 43, and a right flap 44. The one-touch bottom is a box bottom configured so that it can be assembled as the bottom wall 4 when the peripheral wall 6 is folded into a three-dimensional rectangular tube shape.

[0042] The front flap 41 has a main body portion 415, a protruding portion 416, and an adhesive portion 417. The main body portion 415 is connected to the lower end 611 of the front wall 61 and extends rearward from the lower end 611. The rear end 415A of the main body portion 415 is located approximately in the center of the bottom wall 4 in the front-to-rear direction. The protruding portion 416 is a portion on the left side of the main body portion 415 that protrudes rearward from the rear end 415A and is positioned overlapping the rear flap 42. The adhesive portion 417 is a portion on the right side of the main body portion 415 that protrudes rearward from the rear end 415A and is positioned overlapping below the protruding portion 426 of the rear flap 42. The adhesive portion 417 is valley-folded relative to the main body portion 415 along the imaginary line V16 when viewed from below.

[0043] The right flap 44 is connected to the lower end 641 of the right wall 64 and extends leftward from the lower end 641. The right flap 44 is disposed so as to overlap the adhesive portion 417 of the front flap 41. The overlapping portion of the adhesive portion 417 of the front flap 41 and the right flap 44 are adhered to each other by an adhesive portion 451. The adhesive portion 451 may be formed by applying an adhesive material, or may be a double-sided tape in which adhesive material is applied to both sides of the tape in advance.

[0044] The rear flap 42 has a main body portion 425, a protruding portion 426, and an adhesive portion 427. The main body portion 425 is connected to the lower end 621 of the back wall 62 and extends forward from the lower end 621. The front end 425A of the main body portion 425 is located approximately in the center of the bottom wall 4 in the front-to-rear direction. The protruding portion 426 is a portion on the right side of the main body portion 425 that protrudes forward more than the front end 425A and is positioned overlapping the front flap 41. The adhesive portion 427 is a portion on the left side of the main body portion 425 that protrudes forward more than the front end 425A and is positioned overlapping under the protruding portion 416 of the front flap 41. The adhesive portion 427 is valley-folded relative to the main body portion 425 along the imaginary line V17 when viewed from below. The rear flap 42 and the front flap 41 have symmetrical shapes.

[0045] The left flap 43 is connected to the lower end 631 of the left wall 63 and extends rightward from the lower end 631. The left flap 43 is disposed overlapping the adhesive portion 427 of the rear flap 42. The overlapping portion of the adhesive portion 427 of the rear flap 42 and the left flap 43 are adhered to each other by an adhesive portion 452. Like the adhesive portion 451, the adhesive portion 452 may be formed by applying an adhesive material, or may be a double-sided tape in which adhesive material is applied to both sides of the tape in advance. The left flap 43 and the right flap 44 have symmetrical shapes.

[0046] The tape cassette 8 will be described with reference to Figure 1. The tape cassette 8 comprises a case 81 and a printing tape 89. The case 81 is a rectangular parallelepiped that is longer in the left-right direction than in the front-to-back direction, and is longer in the up-down direction than in the left-to-right direction. The printing tape 89 is long and is stored in the case 81. The width direction (short direction) of the printing tape 89 is the front-to-back direction. Therefore, the width direction of the tape cassette 8 is the front-to-back direction. In the tape cassette 8, as the length in the width direction (tape width) of the printing tape 89 increases, the width of the case 81 in the front-to-back direction also increases.

[0047] In the first embodiment, the case 81 has a front wall 82, a rear wall 83, and a peripheral wall 84. The front wall 82 and the rear wall 83 extend perpendicular to the front-to-rear direction and are aligned with each other in the front-to-rear direction. The front wall 82 is located at the front end of the case 81. The rear wall 83 is located at the rear end of the case 81.

[0048] The peripheral wall 84 extends from the peripheral edge 831 of the rear wall 83 to the peripheral edge 821 of the front wall 82. The peripheral wall 84 is in the shape of a rectangular tube and includes a lower wall 85 and an upper wall 86. The lower wall 85 and the upper wall 86 each extend perpendicular to the up-down direction and are aligned with each other in the up-down direction. The lower wall 85 is located at the lower end of the case 81. The upper wall 86 is located at the upper end of the case 81. The upper wall 86 is provided with an outlet 88 for discharging the printing tape 89 stored in the case 81 to the outside of the case 81. The outlet 88 protrudes above the upper wall 86.

[0049] The tape cassette 8 is a consumable item and is used for printing by a printer. For example, the tape cassette 8 is used while attached to the printer. The printer prints an image on the printing tape 89 while pulling the printing tape 89 out of the case 81. The printer ejects the printing tape 89 with the printed image out of the case 81 through the ejection port 88. This creates a label with the image printed on the printing tape 89.

[0050] The mount 100A will be described with reference to Figure 5. Hereinafter, the left, right, bottom, and top of Figure 5 will be referred to as the negative X direction, positive X direction, negative Y direction, and positive Y direction of the mount 100A, respectively. In Figure 5, imaginary lines V0, V1, V2, V3, V4, V5, V6, V7, V8, V9, V10, V11, V12, V13, V14, V15, V16, and V17 indicate the boundaries between adjacent components of the storage box 1A. For example, imaginary line V0 indicates the boundary between the spine wall 62 and the header piece 31.

[0051] The backing sheet 100A is a single sheet cut to a predetermined shape and may be made of cardboard, thin paper, corrugated cardboard, or the like. The backing sheet 100A includes a bottom wall 4, a top wall 5, a peripheral wall 6, and a header 3. The peripheral wall 6 is located in the center of the backing sheet 100A in the Y direction. In the peripheral wall 6, the front wall 61, the spine wall 62, the left wall 63, and the right wall 64 are arranged in succession from the positive X direction to the negative X direction in the order of right wall 64, front wall 61, left wall 63, and spine wall 62. Furthermore, a glue tab 65 is arranged adjacent to the spine wall 62 in the negative X direction. The glue tab 65 is formed at the lower end of the spine wall 62, in the positive Y direction, relative to the position where the starting point region R12 is formed.

[0052] The starting point region R11 is an area surrounded by the perforation 623, the cut line 625, and the imaginary line V6, and is provided at the end of the left wall 63 in the negative Y direction. The perforation 623 extends in an arc shape approximately a quarter of a circle from the end of the imaginary line V3, which marks the boundary between the spine wall 62 and the left wall 63, toward the inside of the left wall 63, and further extends in the positive X direction to the imaginary line V2, which marks the boundary between the left wall 63 and the front wall 61. The cut line 625 cuts the portion from the end of the imaginary line V2 in the negative Y direction to the end of the perforation 623 in the positive X direction. The starting point region R12 is an area surrounded by the perforation 624, the right end of the right wall 64, and the imaginary line V7, and is provided at the end of the right wall 64 in the negative Y direction. The perforation 624 extends in an arc shape approximately a quarter circle from the Y-negative end of the imaginary line V1 indicating the boundary between the front wall 61 and the right wall 64 toward the inside of the right wall 64, and further extends in the X-positive direction to the right end of the right wall 64.

[0053] The bottom wall 4 is disposed in the negative Y direction of the peripheral wall 6. Specifically, the rear flap 42 is disposed in the negative Y direction of the spine wall 62 and is continuous with the spine wall 62. The protruding portion 426 of the rear flap 42 protrudes in the negative Y direction further than the front end 425A of the main body portion 425 in the negative X direction of the main body portion 425. The adhesive portion 427 protrudes in the negative Y direction further than the front end 425A of the main body portion 425 in the positive X direction of the main body portion 425. The front flap 41 is disposed in the negative Y direction of the front wall 61 and is continuous with the front wall 61. The front flap 41 has the same shape as the rear flap 42. The protruding portion 416 of the front flap 41 protrudes in the negative Y direction further than the rear end 415A of the main body portion 415 in the negative X direction of the main body portion 415. The adhesive portion 417 protrudes in the negative Y direction further than the rear end 415A of the main body portion 415 in the positive X direction of the main body portion 415.

[0054] The left flap 43 is disposed in the negative Y direction of the left wall 63 and is continuous with the left wall 63. The left flap 43 is trapezoidal in shape, with its width in the X direction narrowing as it extends in the negative Y direction, and the inclination of the side in the positive X direction is greater than the inclination of the side in the negative X direction. The right flap 44 is disposed in the negative Y direction of the right wall 64 and is continuous with the right wall 64. The right flap 44 has the same shape as the left flap 43 and is trapezoidal in shape, with its width in the X direction narrowing as it extends in the negative Y direction, and the inclination of the side in the positive X direction is greater than the inclination of the side in the negative X direction.

[0055] The top wall 5 and the header 3 are arranged in the Y-positive direction of the peripheral wall 6. Specifically, in the header 3, the header piece 31 is arranged in the Y-positive direction of the back wall 62 and is continuous with the back wall 62. The header piece 32 is arranged in the Y-positive direction of the header piece 31 and is continuous with the header piece 31.

[0056] In the top wall 5, the female flap 52 is arranged in the positive Y direction of the header piece 31 and is connected to the header piece 31. The male flap 51 is arranged in the positive Y direction of the front wall 61 and is connected to the front wall 61. The left flap 53 is arranged in the positive Y direction of the left wall 63 and is connected to the left wall 63. The right flap 54 is arranged in the positive Y direction of the right wall 64 and is connected to the right wall 64.

[0057] A method for assembling storage box 1A from mount 100A will be described with reference to Figures 5 to 10. Hereinafter, for each component, the surface of mount 100A shown in Figure 5 facing the front of the page will be referred to as the "front side" of each component, and the surface of mount 100A shown in Figure 5 facing the back of the page will be referred to as the "back side" of each component.

[0058] Folding the mount 100A along the boundary between a pair of adjacent components in a direction in which the back surfaces of the components face each other is called a "mountain fold." Folding the mount 100A along the boundary between a pair of adjacent components in a direction in which the front surfaces of the components face each other is called a "valley fold." For example, "mountain-folding the mount 100A along the imaginary line V1" means that the mount 100A is folded along the imaginary line V1 in a direction in which the back surfaces of the right wall 64 and the front wall 61 face each other. In the first embodiment, creases are formed on the front surface of the mount 100A along the imaginary lines V1 to V17. On the other hand, no creases are formed on the back surface of the mount 100A.

[0059] As shown in Fig. 6, the back surface of the mount 100A is placed with its back surface facing towards the front of the paper in Fig. 6. The mount 100A is valley-folded to its back surface along imaginary lines V5, V6, V7, and V8 (see Fig. 5). The glued portion 417 of the front flap 41 facing its front surface and the glued portion 427 of the back flap 42 facing its front surface are valley-folded along imaginary lines V16 and V17 (see Fig. 5). As a result, the main body portion 415 and protruding portion 416 of the front flap 41, the main body portion 425 and protruding portion 426 of the back flap 42, the left flap 43, and the right flap 44 are folded with their front surfaces facing up onto the mount 100A facing its back surface. Furthermore, the adhesive portion 417 and the adhesive portion 427 are folded with their back sides facing up onto the main body portion 415 of the front flap 41 facing the front surface and the main body portion 425 of the back flap 42 facing the front surface.

[0060] The backing sheet 100A is valley-folded along imaginary lines V1, V2, V3, and V4 to form creases. Next, an adhesive is applied to the back surface of the glued portion 427 of the rear flap 42 to form a glued portion 452. The spine wall 62 is folded onto the left wall 63 along imaginary line V3. The back surface of the glued portion 427 is placed on the front surface of the left flap 43, and the back surface of the glued portion 427 of the rear flap 42 and the front surface of the left flap 43 are bonded together by the glued portion 452.

[0061] The surface of the glue tab 65 is positioned so that it faces the front of the paper in Figure 6, and an adhesive is applied to the surface. Also, adhesive is applied to the back surface of the glued portion 417 of the front flap 41, forming an adhesive portion 451. The right wall 64 is folded over the front wall 61 along the imaginary line V1. The surface of the right flap 44 is placed over the back surface of the glued portion 417, and the adhesive portion 451 bonds the back surface of the glued portion 417 of the front flap 41 to the surface of the right flap 44. Also, the back surface of the right wall 64 is placed over the surface of the glue tab 65, and the glue tab 65 and the right wall 64 are bonded together by the adhesive. As a result, the spine wall 62 and the right wall 64 are arranged adjacent to each other.

[0062] As shown in FIG. 7 , when the peripheral wall 6 is formed into a three-dimensional rectangular tube shape, the surface of the mount 100A, including each of the flaps, faces outward from the rectangular tube, and the back surface faces inward, i.e., toward the space 7. The right flap 44 and the front flap 41, which are bonded by the adhesive portion 451, are extended from their folded state along the imaginary line V16 to form the right and front portions of the bottom wall 4. The left flap 43 and the rear flap 42, which are bonded by the adhesive portion 452, are extended from their folded state along the imaginary line V17 to form the left and rear portions of the bottom wall 4. The protruding portion 416 of the front flap 41 is placed on top of the glued portion 427 of the rear flap 42 and the left flap 43, with the back surface facing toward the space 7. The protruding portion 426 of the rear flap 42 is placed on top of the glued portion 417 of the front flap 41 and the right flap 44 with the back surface facing into the space 7 , and is disposed on the top layer of the bottom wall 4 .

[0063] As shown in FIG. 8 , when the bottom wall 4 is formed, the box body 2 opens upward. In this state, the tape cassette 8 is stored in the space 7 from above the box body 2 so that the bottom wall 85 faces the back surface of the bottom wall 4 from above. The tape cassette 8 is stored in the storage box 1A with the outlet 88 for the printing tape 89 positioned on the top wall 5 side. The bottom wall 4 is configured so that the protruding portion 426 of the rear flap 42 overlaps the adhesive portion between the glued portion 417 of the front flap 41 and the right flap 44, and the protruding portion 416 of the front flap 41 overlaps the adhesive portion between the glued portion 427 of the rear flap 42 and the left flap 43. The protruding portion 426 of the rear flap 42 and the protruding portion 416 of the front flap 41 support the weight of the tape cassette 8 and prevent the tape cassette 8 from coming into contact with the adhesive portions, thereby preventing the bottom from falling out of the one-touch bottom configuration.

[0064] As shown in FIG. 9, the backing sheet 100A is mountain-folded along the imaginary line V9 and then valley-folded along the imaginary line V10. This forms the header 3, and the female flap layer 502 is placed as the bottom layer of the top wall 5. The backing sheet 100A is mountain-folded along the imaginary lines V11 and V12. This results in a side flap layer 503 composed of a left flap 53 and a right flap 54 being stacked on top of the female flap layer 502 in the top wall 5. Note that the stacking order of the left flap 53 and the right flap 54 in the side flap layer 503 is arbitrary. The backing sheet 100A is mountain-folded along the imaginary line V13 and then valley-folded along the imaginary line V15. This forms the insertion portion 55. The backing sheet 100A is mountain-folded along the imaginary line V14. The insertion portion 55 is inserted inward from the female flap 52 through the insertion opening 521. As a result, the male flap layer 501 is laminated on top of the side flap layer 503, forming the top wall 5 shown in Fig. 2. This completes the assembly of the storage box 1A and the storage of the tape cassette 8 inside the storage box 1A, completing the printing cassette storage unit 20A.

[0065] As shown in FIG. 7, when removing the tape cassette 8 from the storage box 1A, the user pushes the starting region R11 of the left wall 63 and the starting region R12 of the right wall 64 into the box body 2. The starting regions R11 and R12 each have an asymmetrical shape in the front-to-rear direction. The rear end side of the perforation 623 of the starting region R11 is arc-shaped, so the area of ​​the front end side is larger than that of the rear end side. The front end side of the perforation 624 of the starting region R12 is arc-shaped, so the area of ​​the rear end side is larger than that of the front end side (see FIG. 1). This allows the user to easily tear the perforations 623 and 624 using, for example, a fingernail, and easily separate the starting region R11 and the starting region R12 from the left wall 63 and the right wall 64, respectively.

[0066] As shown in FIG. 8 , the case 81 of the tape cassette 8 has a generally central portion of the peripheral wall 84 in the front-to-rear direction that protrudes outward more than the front and rear portions. That is, the case 81 has a recessed portion 81A on its surface that is located closer to the interior of the case 81 than the generally central portion of the peripheral wall 84 in the front-to-rear direction. The recessed portion 81A is formed in a corner portion of the case 81. As shown in FIG. 9 , the front and rear portions of the starting regions R11, R12 in the front-to-rear direction are formed in positions that overlap with the recessed portion 81A at the bottom of the tape cassette 8. Therefore, as shown in FIG. 10 , when opening the bottom wall 4, the user can easily push the starting regions R11, R12 deep into the box main body 2, making it easier to break the starting regions R11, R12 from the left wall 63 and the right wall 64.

[0067] The starting regions R11, R12 are connected to the left flap 43 and the right flap 44 via the lower ends 631, 641 of the left wall 63 and the right wall 64, respectively. That is, the left flap 43 and the right flap 44 are not connected to the left wall 63 and the right wall 64, respectively, because the starting regions R11, R12 are detached from the left wall 63 and the right wall 64. The left flap 43 and the right flap 44 are adhered to the back flap 42 and the front flap 41 via adhesive portions 452, 451, respectively. That is, the left flap 43 and the right flap 44 are connected to the back wall 62 and the front wall 61 via the lower ends 621, 611, because the starting regions R11, R12 are detached from the left wall 63 and the right wall 64. Therefore, the user can easily open the bottom wall 4 by straightening the bends of the rear flap 42 and the front flap 41 at the lower ends 621 and 611, respectively.

[0068] The user can grasp the peripheral wall 84 of the case 81 that is exposed on the left wall 63 and the right wall 64 due to the separation of the starting areas R11, R12, and pull out the tape cassette 8 from the storage box 1A. At this time, the tape cassette 8 is placed in the space 7 of the storage box 1A with the ejection outlet 88 facing the top wall 5 of the storage box 1A. Therefore, the user does not have to touch the ejection outlet 88 or the printing tape 89. In this way, the printing cassette storage unit 20A has a one-touch bottom type, and the bottom wall 4 can be easily opened and the tape cassette 8 can be removed simply by separating the two starting areas R11, R12 from the box body 2.

[0069] The main effects of the storage box 1A in the first embodiment described above will be described. The mount 100A also has the same effects as the storage box 1A, since the storage box 1A is formed from the mount 100A.

[0070] By cutting along the perforation 624, the portion of the right wall 64 that is connected to the right flap 44 via the lower end 641, which is cut along the perforation 624 (starting area R12), becomes adhered to the front flap 41 via the adhesive portion 451. Because the front flap 41 is connected to the front wall 61 via the lower end 611, the front wall 61 and the right wall 64 are separated. Therefore, the user can open the bottom wall 4 that forms the one-touch bottom and remove the tape cassette 8 from the storage box 1A.

[0071] The user can open the bottom wall 4 that constitutes the one-touch bottom by tearing the perforation 624, and remove the tape cassette 8 from the storage box 1A.

[0072] Perforations 624, 623, and cut lines 625 are formed on right wall 64 and left wall 63, respectively, which face each other in the left-right direction, and front wall 61 and right wall 64 can be separated by breaking perforations 624, and spine wall 62 and left wall 63 can be separated by breaking perforations 623 and cut lines 625. Thus, by breaking perforations 624, 623, and cut lines 625, the user can completely open bottom wall 4, which constitutes the one-touch bottom, and remove tape cassette 8 from storage box 1A.

[0073] The starting point region R12 has an asymmetrical shape in the front-to-rear direction, and the area of ​​the portion closer to the front wall 61 is smaller than the area of ​​the portion further away. When a user tears the perforation 624 along the shape of the starting point region R12, the printing cassette storage body 20A encourages the direction of force used to break the right wall 64 through the perforation 624 to be directed in the appropriate direction. This allows the user to easily open the bottom wall 4 that forms the one-touch bottom, and remove the tape cassette 8 from the storage box 1A. The same applies to the starting point region R11.

[0074] The adhesive margin 65 is formed at a position above and away from the position where the perforation 624 is formed. Therefore, the position where the perforation 624 is formed does not overlap with the adhesive margin 65. Therefore, the adhesive applied to the adhesive margin 65 does not prevent the perforation 624 from being separated, and the user can easily open the bottom wall 4 and remove the tape cassette 8 from the storage box 1A.

[0075] The perforation 624 is formed at a position where the starting region R12 overlaps with the recessed portion 81A of the case 81 of the tape cassette 8. Therefore, a user can break the perforation 624 by pushing it toward the recessed portion 81A, thereby easily opening the bottom wall 4 and removing the tape cassette 8 from the storage box 1A. The same applies to the starting region R11.

[0076] The ejection port 88 of the tape cassette 8 stored in the storage box 1A is located on the top wall 5 side opposite the bottom wall 4. Therefore, when the user removes the tape cassette 8 from the storage box 1A, it is difficult for the user to touch the printing tape 89.

[0077] In the first embodiment, the tape cassette 8 is an example of a "printing cassette" of the present invention. The storage box 1A is an example of a "storage box" of the present invention. The printing cassette storage body 20A is an example of a "printing cassette storage body" of the present invention. The up-down direction is an example of a "first direction" of the present invention. The bottom wall 4 is an example of a "first wall" of the present invention. The top wall 5 is an example of a "second wall" of the present invention. The front-rear direction is an example of a "second direction" of the present invention. The front wall 61 is an example of a "first peripheral wall" of the present invention. The back wall 62 is an example of a "second peripheral wall" of the present invention. The left-right direction is an example of a "third direction" of the present invention. The right wall 64 is an example of a "third peripheral wall" of the present invention. The left wall 63 is an example of a "fourth peripheral wall" of the present invention. The downward direction is an example of a "first specific direction" of the present invention. The lower end 611 is an example of a "first connecting end" of the present invention. The front flap 41 is an example of a "first flap" of the present invention. The lower end 621 is an example of a "second connecting end" of the present invention. The back flap 42 is an example of a "second flap" of the present invention. The lower end 641 is an example of a "third connecting end" of the present invention. The right flap 44 is an example of a "third flap" of the present invention. The lower end 631 is an example of a "fourth connecting end" of the present invention. The left flap 43 is an example of a "fourth flap" of the present invention. The adhesive portion 451 is an example of a "first adhesive portion" of the present invention. The adhesive portion 452 is an example of a "second adhesive portion" of the present invention. The perforation 624 is an example of a "first separating portion" of the present invention.

[0078] The perforation 623 and the cut line 625 are an example of a "second separation portion" of the present invention. The imaginary line V2 indicating the boundary between the spine wall 62 and the left wall 63 is an example of a "fifth connection end" of the present invention. The starting region R11 is an example of a "separable portion" of the present invention. The backing sheet 100A is an example of a "sheet" of the present invention. The glue margin 65 is an example of a "bonded portion" of the present invention. The upward direction is an example of an "opposite direction" of the present invention.

[0079] The present invention may be modified from the first embodiment. The various modified examples described below may be combined with each other and may be applied to any storage box 1A, provided that no contradictions arise. The one-touch bottom is configured by adhering the front flap 41 to the right flap 44 and the rear flap 42 to the left flap 43, but it may also be configured by adhering the front flap 41 to the left flap 43 and the rear flap 42 to the right flap 44.

[0080] Although the perforation 623 is formed in the left wall 63, it may also be formed in the spine wall 62 and torn so that the rear flap 42 can be separated from the spine wall 62. When the bottom wall 4 is opened, the right flap 44 is separated from the right wall 64 by tearing the perforation 624. Because the right flap 44 is adhered to the front flap 41 via the adhesive portion 451, the right wall 64 and the front wall 61 are not connected to each other. Furthermore, the rear flap 42 is separated from the spine wall 62 by tearing the perforation formed in the spine wall 62. Because the rear flap 42 is adhered to the left flap 43 via the adhesive portion 452, the spine wall 62 and the left wall 63 are not connected to each other. Therefore, by straightening the bends of the front flap 41 and the left flap 43 at the lower ends 611 and 631, respectively, the user can easily open the bottom wall 4, which constitutes the one-touch bottom, completely and remove the tape cassette 8 from the storage box 1A. Furthermore, the perforations formed in the back wall 62 and the perforations 624 in the right wall 64 can be seen from the corners of the right wall 64, the back wall 62 and the bottom wall 4 at the same time, so the user can break the perforations in the back wall 62 and the perforations 624 in the right wall 64 to open the bottom wall 4 without changing the orientation of the storage box 1A.

[0081] In the above-described modified example, perforation 624 may be formed in front wall 61, while perforation 623 in left wall 63 may remain as is. In this case, front wall 61 and right wall 64 can be separated by tearing the perforation in front wall 61, and left wall 63 and back wall 62 can be separated by tearing perforation 623 in left wall 63, allowing the user to easily open the entire bottom wall 4 that constitutes the one-touch bottom. Furthermore, the perforation formed in front wall 61 and perforation 623 in left wall 63 can be seen at the corners of left wall 63, front wall 61, and bottom wall 4 at the same time, allowing the user to tear perforation 623 in front wall 61 and perforation 623 in left wall 63 without changing the orientation of storage box 1A.

[0082] Furthermore, in the above-described modified example, the perforation formed in the front wall 61 and the perforation 623 formed in the left wall 63 may be configured to be connected across the imaginary line V2, which serves as a fold line connecting the left wall 63 and the front wall 61. In this case, the user can tear the perforation in the front wall 61 and the perforation 623 in the left wall 63 together as one continuous perforation. Thus, the user can open the bottom wall 4, which constitutes the one-touch bottom, with a single separation operation, and remove the tape cassette 8 from the storage box 1A.

[0083] Similarly, the perforation formed in the spine wall 62 and the perforation 624 formed in the right wall 64 may be formed as one continuous perforation. In this case, a second adhesive margin may be provided below the adhesive margin 65 to adhere the area separated from the spine wall 62 by the perforation formed in the spine wall 62 to the starting region R12 of the right wall 64, and the two may be adhered to each other. In this way, the perforation in the spine wall 62 and the perforation 624 in the right wall 64 can be torn together, and the bottom wall 4 that constitutes the one-touch bottom can be opened with a single separation operation.

[0084] While the starting regions R11 and R12 are asymmetric in the front-to-rear direction, they may be symmetric as long as the left flap 43 and the right flap 44 can be separated from the left wall 63 and the right wall 64 together with their respective lower ends 631 and 641. While the perforations 623 and 624 are arc-shaped on one side in the front-to-rear direction, they may also be arc-shaped on both sides, or may be slanted vertically. Alternatively, the perforations 623 and 624 may be linearly inclined vertically from one side to the other in the front-to-rear direction. The perforations 623 and 624 may also be formed at the lower end 631 of the left wall 63 and the lower end 641 of the right wall 64, respectively.

[0085] Although the glue margin 65 is formed at a position above and away from the position where the perforation 624 is formed, it may be formed at a position overlapping the perforation 624. In this case, a perforation or a cut line may be formed at the portion where the glue margin 65 and the spine wall 62 are connected at the position overlapping the perforation 624.

[0086] Next, a second embodiment of the present invention will be described. Note that a printing cassette holder 20B of the second embodiment differs from the printing cassette holder 20A of the first embodiment in the configuration of the bottom wall 4 and starting areas R11, R12, but the other parts are the same. Therefore, in the following explanation, explanations of the same parts will be omitted or simplified, and only different parts will be explained.

[0087] As shown in FIG. 11 , the bottom wall 104 of the printing cassette holder 20B is a so-called one-touch bottom and includes a front flap 141, a rear flap 142, a left flap 143, and a right flap 144. The front flap 141 has a main body 715, a protruding portion 716, an adhesive portion 717, and a tab 718. The main body 715 is connected to the lower end 611 of the front wall 61 and extends rearward from the lower end 611. The rear end 715A of the main body 715 is located approximately in the center of the bottom wall 104 in the front-to-rear direction. The protruding portion 716 is a portion of the left side of the main body 715 that protrudes rearward beyond the rear end 715A and is positioned above the rear flap 142. The adhesive portion 717 is a portion of the right side of the main body 715 that protrudes rearward beyond the rear end 715A and is positioned below the protruding portion 726 of the rear flap 142. The adhesive portion 717 is folded along the perforation 756 toward the main body portion 715. The tab 718 protrudes in a semicircular shape from the adhesive portion 717 and is located to the right rear of the rear end 715A of the main body portion 715. The user grasps the tab 718 when the bottom wall 104 is opened.

[0088] The right flap 144 is connected to the lower end 641 of the right wall 64 and extends leftward from the lower end 641. The right flap 144 is positioned overlapping the glued portion 717 of the front flap 141. It does not overlap with the tab 718. The overlapping portion of the glued portion 717 of the front flap 141 and the right flap 144 are adhered to each other by an adhesive portion 751 coated with an adhesive.

[0089] The rear flap 142 has a main body portion 725, a protruding portion 726, an adhesive portion 727, and a tab 728. The main body portion 725 is connected to the lower end 621 of the spine wall 62 and extends forward from the lower end 621. A front end 725A of the main body portion 725 is located approximately in the center of the bottom wall 104 in the front-to-rear direction. The protruding portion 726 is a portion on the right side of the main body portion 725 that protrudes forward more than the front end 725A and is positioned overlapping the front flap 141. The adhesive portion 727 is a portion on the left side of the main body portion 725 that protrudes forward more than the front end 725A and is positioned overlapping under the protruding portion 716 of the front flap 141. The adhesive portion 727 is valley-folded along the perforation 757 relative to the main body portion 725. The tab 728 protrudes in a semicircular shape from the adhesive portion 727 and is located on the left front side of the front end 725A of the main body portion 725. The user grasps the tab 728 when opening the bottom wall 104. The rear flap 142 and the front flap 141 have symmetrical shapes.

[0090] The left flap 143 is connected to the lower end 631 of the left wall 63 and extends rightward from the lower end 631. The left flap 143 is positioned overlapping the adhesive portion 727 of the rear flap 142. It does not overlap the tab 728. The overlapping portion of the adhesive portion 727 of the rear flap 142 and the left flap 143 are adhered to each other by an adhesive portion 752 to which an adhesive is applied. The left flap 143 and the right flap 144 have symmetrical shapes.

[0091] Next, the configuration of the bottom wall 104 of the backing sheet 100B, which differs from that of the backing sheet 100A, will be described. As shown in FIG. 12, the bottom wall 104 is disposed in the negative Y direction of the peripheral wall 6. The rear flap 142 is disposed in the negative Y direction of the spine wall 62 and is continuous with the spine wall 62. The protruding portion 726 of the rear flap 42 protrudes in the negative Y direction from the front end 725A of the main body portion 725 in the negative X direction of the main body portion 725. The adhesive portion 727 protrudes in the negative Y direction from the front end 725A of the main body portion 725 in the positive X direction of the main body portion 725. The tab 728 has a semicircular shape that protrudes in both the negative X and negative Y directions from the adhesive portion 727.

[0092] The front flap 141 is disposed in the negative Y direction of the front wall 61 and is continuous with the front wall 61. The front flap 141 has the same shape as the rear flap 142. The protruding portion 716 of the front flap 141 protrudes in the negative Y direction beyond the rear end 715A of the main body 715 in the negative X direction of the main body 715. The adhesive portion 717 protrudes in the negative Y direction beyond the rear end 715A of the main body 715 in the positive X direction of the main body 715. The tab 718 has a semicircular shape that protrudes in both the negative X and negative Y directions of the adhesive portion 717.

[0093] The left flap 143 is disposed in the negative Y direction of the left wall 63 and is continuous with the left wall 63. The left flap 143 is trapezoidal in shape, with its width in the X direction narrowing as it extends in the negative Y direction, and the inclination of the side in the positive X direction is greater than the inclination of the side in the negative X direction. The right flap 144 is disposed in the negative Y direction of the right wall 64 and is continuous with the right wall 64. The right flap 144 has the same shape as the left flap 143 and is trapezoidal in shape, with its width in the X direction narrowing as it extends in the negative Y direction, and the inclination of the tail side in the positive X direction is greater than the inclination of the side in the negative X direction.

[0094] 11 and 12, a method for assembling a storage box 1B from a mount 100B will be described. The mount 100B shown in FIG. 12 is placed with its back surface facing toward the viewer and is valley-folded toward the back surface along imaginary lines V5, V6, V7, and V8. The glued portion 717 and tab 718 of the front flap 141 facing the front, and the glued portion 727 and tab 728 of the back flap 142 facing the front, are valley-folded along perforations 756 and 757. As a result, the main body 715 and protruding portion 716 of the front flap 141, the main body 725 and protruding portion 726 of the back flap 142, the left flap 143, and the right flap 144 are folded with their front surfaces facing up onto the mount 100B facing the back. Furthermore, the adhesive portion 717 and the tab 718, and the adhesive portion 727 and the tab 728 are folded back onto the main body portion 715 of the front flap 141 facing the front and the main body portion 725 of the back flap 142 facing the front.

[0095] The backing sheet 100B is valley-folded along imaginary lines V1, V2, V3, and V4 to form creases. Next, an adhesive is applied to the back surface of the glued portion 727 of the rear flap 142 to form an adhesive portion 752. The spine wall 62 is folded onto the left wall 63 along imaginary line V3. The back surface of the glued portion 727 is placed on the front surface of the left flap 143, and the back surface of the glued portion 727 of the rear flap 142 and the front surface of the left flap 143 are adhered to each other by the adhesive portion 752. The adhesive portion 752 does not contact the tab 718.

[0096] An adhesive is applied to the front surface of the glue tab 65 and the back surface of the glued portion 717 of the front flap 141. An adhesive portion 751 is formed. The right wall 64 is folded onto the front wall 61 along the imaginary line V1. The front surface of the right flap 144 is placed on the back surface of the glued portion 717, and the adhesive portion 751 bonds the back surface of the glued portion 717 of the front flap 141 to the front surface of the right flap 144. In addition, the back surface of the right wall 64 is placed on the front surface of the glue tab 65, and the glue tab 65 and the right wall 64 are bonded together with the adhesive. As a result, the spine wall 62 and the right wall 64 are arranged adjacent to each other.

[0097] As shown in FIG. 11 , when the peripheral wall 6 is formed into a three-dimensional rectangular tube shape, the right flap 144 and the front flap 141, which are bonded by the adhesive portion 751, are extended from their folded state at the perforation 756 to form the right and front portions of the bottom wall 104. The left flap 143 and the rear flap 142, which are bonded by the adhesive portion 752, are extended from their folded state at the perforation 757 to form the left and rear portions of the bottom wall 104. The protruding portion 716 of the front flap 141 is overlapped on the adhesive portion 727 of the rear flap 142 and the left flap 143 with its back surface facing into the space 7, and is disposed at the top of the bottom wall 104. The protruding portion 726 of the rear flap 142 is overlapped on the adhesive portion 717 of the front flap 141 and the right flap 144 with its back surface facing into the space 7, and is disposed at the top of the bottom wall 104. The tabs 718, 728 are arranged within the range of the bottom wall 104 when viewed from the bottom and do not protrude from the periphery 40, so that, for example, during transportation, the tabs 718, 728 do not get caught, the perforations 756, 757 do not break, and the bottom wall 104 does not open inadvertently.

[0098] When the tape cassette 8 is stored in the space 7 and the top wall 5 is formed, the assembly of the storage box 1B and the storage of the tape cassette 8 in the storage box 1B are completed, and the printing cassette storage unit 20B is completed.

[0099] As shown in FIG. 13 , when removing the tape cassette 8 from the storage box 1B, the user grasps the tabs 718, 728 on the bottom wall 104 with their fingers and pulls them to break the perforations 756, 757. The perforations 756, 757 are formed at the fold between the main body portion 715 and the adhesive portion 717 of the front flap 141 and at the fold between the main body portion 725 and the adhesive portion 727 of the rear flap 142, respectively, and are therefore prone to breaking due to creases. By breaking the perforations 756, 757, the adhesive portions 717, 727 of the front flap 141 and the rear flap 142, which are connected to the tabs 718, 728, are separated from the main body portions 715, 725, respectively. The adhesive portions 717, 727 separated at the perforations 756, 757 are connected to the right flap 144 and the left flap 143 via the adhesive portions 751, 752, respectively. The right flap 144 and the left flap 143 are connected to the bottom edge 641 of the right wall 64 and the bottom edge 631 of the left wall 63, respectively. Furthermore, the main body portions 715 and 725, separated by perforations 756 and 757, are connected to the bottom edge 611 of the front wall 61 and the bottom edge 621 of the back wall 62, respectively. Therefore, by straightening the bends of the front flap 141, the rear flap 142, the left flap 143, and the right flap 144, the user can easily open the bottom wall 104 of the one-touch bottom type. The tape cassette 8 is placed in the space 7 of the storage box 1B with the ejection opening 88 facing the top wall 5 of the storage box 1B. Therefore, the user can remove the tape cassette 8 without touching the ejection opening 88 or the printing tape 89.

[0100] The main effects of the storage box 1B in the second embodiment explained above will be described. The mount 100B also has the same effects as the storage box 1B, since the storage box 1B is formed from the mount 100B.

[0101] By separating perforation 756, front flap 141 connected to front wall 61 and right flap 144 connected to right wall 64 are separated, thereby releasing the state in which front wall 61 and right wall 64 are connected via bottom wall 104. Thus, the user can open bottom wall 104, which forms the one-touch bottom, and remove tape cassette 8 from storage box 1B.

[0102] As the length of the storage box 1B in the front-to-rear direction increases, the length of the edge parallel to the lower end 611 of the glued portion 717 of the front flap 141 becomes relatively shorter, and the length of the non-parallel edge becomes relatively longer. Because the tab 718 connects to the glued portion 717 at an edge that is not parallel to the lower end 611, the connection length between the glued portion 717 and the tab 718 can be secured, and strength can be increased.

[0103] Perforations 756 and 757 are formed in front flap 141 and rear flap 142, respectively. By breaking perforation 756, front wall 61 and right wall 64 can be separated, and by breaking perforation 757, spine wall 62 and left wall 63 can be separated. Therefore, by breaking perforations 756 and perforation 757, the user can completely open bottom wall 104, which constitutes the one-touch bottom, and remove tape cassette 8 from storage box 1B.

[0104] By forming perforation 756 at the crease between main body portion 715 and adhesive portion 717, and by forming perforation 757 at the crease between main body portion 725 and adhesive portion 727, the user can easily tear perforation 756 and perforation 757 and remove tape cassette 8 from storage box 1B.

[0105] The tabs 718, 728 are formed on the bottom wall 104. Therefore, when multiple printing cassette housing units 20B are packed for transport, it is possible to prevent the tabs 718, 728 from getting caught on adjacent printing cassette housing units 20B and causing the perforations 756, 757 to break.

[0106] The ejection port 88 of the tape cassette 8 stored in the storage box 1B is located on the top wall 5 side opposite the bottom wall 104. Therefore, when the user removes the tape cassette 8 from the storage box 1B, it is difficult for the user to touch the printing tape 89.

[0107] In the second embodiment, the storage box 1B is an example of the "storage box" of the present invention. The printing cassette storage unit 20B is an example of the "printing cassette storage unit" of the present invention. The bottom wall 104 is an example of the "first wall" of the present invention. The front flap 141 is an example of the "first flap" of the present invention. The rear flap 142 is an example of the "second flap" of the present invention. The right flap 144 is an example of the "third flap" of the present invention. The left flap 143 is an example of the "fourth flap" of the present invention. The adhesive portion 751 is an example of the "first adhesive portion" of the present invention. The adhesive portion 752 is an example of the "second adhesive portion" of the present invention. The perforation 756 is an example of the "first separation portion" of the present invention. The tab 718 is an example of the "first starting portion" of the present invention. The perforation 757 is an example of the "second separation portion" of the present invention. The tab 728 is an example of the "second starting portion" of the present invention. The portion of the front flap 41 that is folded along the perforation 756 formed between the main body portion 715 and the glued portion 717 is an example of a "first fold" in the present invention. The portion of the back flap 42 that is folded along the perforation 757 formed between the main body portion 725 and the glued portion 727 is an example of a "second fold" in the present invention.

[0108] The present invention may be modified from the second embodiment. The various modified examples described below may be combined with each other and may be applied to any storage box 1B, as long as no contradictions arise. The one-touch bottom is configured by bonding the front flap 141 and the right flap 144 together and bonding the rear flap 142 and the left flap 143 together, but it may also be configured by bonding the front flap 141 and the left flap 143 together and bonding the rear flap 142 and the right flap 144 together.

[0109] Although the tab 718 of the front flap 141 and the tab 728 of the rear flap 142 are connected to the adhesive portions 717 and 727, respectively, they may also be provided on the main body portions 715 and 725. For example, in the printing cassette storage unit 20C shown in FIG. 14, the tape cassette (not shown) stored in the storage box 1C uses a case whose length in the front-to-rear direction is shorter than that of the tape cassette 8 because the width of the tape stored therein is short. Therefore, the length in the front-to-rear direction of the storage box 1C that stores the tape cassette is shorter than that of the storage box 1B. In this case, it is difficult to ensure that the adhesive portions 817 and 827 of the front flap 241 and the rear flap 242 are of sufficient length at the connection portions with the tabs.

[0110] Therefore, in the storage box 1C, the tabs 818, 828 are connected to the main body portions 815, 825 of the front flap 241 and the rear flap 242. The rear end 815A and the front end 825A of the main body portions 815, 825 are parallel to the lower ends 611, 621. Because the length of the storage box 1C in the front-to-rear direction is shortened, the rear end 815A and the front end 825A can be secured to be relatively longer compared to the connection portions when tabs are provided on the glued portions 817, 827. Perforations 856, 857 are formed between the main body portions 815, 825 and the glued portions 817, 827, and pulling the tabs 818, 828 breaks the perforations 856, 857, separating the main body portions 815, 825 from the glued portions 817, 827. Furthermore, the protrusions 816, 826 of the front flap 241 and the rear flap 242 are configured to overlap the rear flap 242 and the front flap 241, respectively, when the one-touch bottom is assembled. For this reason, the main body portions 815, 825 are further formed with perforations 858, 859 that can be torn by pulling the tabs 818, 828.

[0111] When removing a tape cassette from the storage box 1C of the printing cassette storage unit 20C configured as described above, the user grasps the tabs 818, 828 on the bottom wall 204 with their fingers and pulls them to break the perforations 856, 857, 858, 859. The perforations 856, 857 are formed at the folds between the main body portions 815, 825 and the adhesive portions 817, 827, and are therefore prone to breaking due to the crease. Breaking the perforations 856, 857 separates the adhesive portions 817, 827 from the main body portions 815, 825. Breaking the perforations 858, 859 separates the protruding portions 816, 826 from the main body portions 815, 825. The user can easily open the one-touch bottom wall 204 and remove the tape cassette by straightening the bends of the front flap 241, the rear flap 242, the left flap 243, and the right flap 244. By providing the tabs 818, 828 at the rear end 815A and the front end 825A of the main body portions 815, 825 that are parallel to the lower ends 611, 621 in this way, the connection length of the tabs 818, 828 with the front flap 241 and the rear flap 242 can be ensured, thereby increasing strength.

[0112] Other modifications will be described. The length relationships of the box body 2 in the up-down, left-right, and front-rear directions are not limited to those in the first and second embodiments. For example, the length of the box body 2 in the front-rear direction may be greater than the length of the box body 2 in the left-right direction.

[0113] In the first and second embodiments, the mounts 100A and 100B are not limited to the shapes of the first and second embodiments as long as they are configured to form the storage boxes 1A and 1B when assembled together. A plastic sheet or the like may be used instead of the mounts 100A and 100B as long as it is a sheet that can be folded and maintained in a folded state.

[0114] In the first and second embodiments, other stored items may be stored in the space 7 instead of the tape cassette 8. The other stored items are, for example, consumables used for printing, such as ink tanks, ink cartridges, or ink ribbon cassettes. The other stored items may also be consumables used for purposes other than printing. The other stored items do not have to be consumables, and may be food, etc.

[0115] In the first and second embodiments, the tape cassette 8 is placed in the space 7 with the lower wall 85 facing the bottom wall 4, 104. However, the tape cassette 8 may also be placed in the space 7 with a wall other than the lower wall 85, for example, the upper wall 86, facing the bottom wall 4, 104.

[0116] In the first and second embodiments, the female flap 52 is connected to the upper end 622 of the back wall 62 via the header 3. Alternatively, the female flap 52 may be directly connected to the upper end 622 of the back wall 62. In this case, the header 3 may be omitted, or the female flap 52 may be connected to the upper end 632 of the left wall 63 or the upper end 642 of the right wall 64.

[0117] In the first and second embodiments, the header 3 has header pieces 31 and 32. However, the header 3 may be configured with either the header piece 31 or the header piece 32. The number and shape of the holes 30 are not limited to those in the first and second embodiments. The header 3 does not necessarily have to be provided with the holes 30. [Explanation of symbols]
