Description

[Technical field]

[0001] The present invention relates to a paper display device that can be used in a form selected from a hanging form and a tabletop form. [Background technology]

[0002] A storage case for pamphlets that can be used as a free-standing stand case, a hanging case, or a carrying case by changing the shape of the variable case part is known (Patent Document 1). The case base of the storage case for pamphlets is formed of a front panel, left and right side panels, a bottom panel, and a lower back panel. The variable case part is formed of an upper back panel, a top panel, and a cover panel. When used as a carrying case, the upper back panel covers the upper back part of the case base, the top panel covers the upper end opening of the case base, and the cover panel covers the notched groove part of the front panel. When used as a free-standing stand case, the upper back panel is disposed diagonally downward toward the rear, and the top panel and cover panel are disposed horizontally. When used as a hanging case, the upper back panel covers the upper back part of the case base, and the cover panel is folded back to overlap the top panel and upper back panel.

[0003] [Patent Document 1] Utility Model Registration No. 3130881 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned storage case for pamphlets, when used as a carrying case, the cover plate of the variable case portion covers the notched groove portion of the front plate of the case base, but most of the front plate except for the notched groove portion and the left and right side plates are exposed. Therefore, there is a risk that the front plate, left and right side plates, etc. will be scratched or dirty during transportation of the carrying case. Since the front plate, left and right side plates, etc. are exposed even when used as a freestanding case or a hanging case, if the front plate, etc. are scratched or dirty, the cosmetic appearance of the case may be deteriorated.

[0005] In addition, when used as a carrying case, the upper back plate of the variable case portion constitutes the upper back side of the case base, and when used as a self-standing stand case, the upper back plate is folded down. Therefore, in the self-standing stand case, a large opening is created on the upper back side of the case base, and there is a risk that pamphlets (items) may hang down from the large opening.

[0006] The present invention has been made in consideration of the above circumstances, and provides a display device that can properly hold an item while maintaining its aesthetic appeal. [Means for solving the problem]

[0007] The present invention is a paper display device that can be used in a form selected from a hanging form and a tabletop form, and comprises a storage case formed in a rectangular tube shape having a bottom and capable of storing items in and out, and a pair of side covers connected to both left and right ends of the rear of the storage case, wherein the pair of side covers become exterior parts that cover the pair of left and right sides and the front of the storage case when the display device is transported or stored, and become reinforcing parts that cover the rear of the storage case when the display device is used in the hanging form, and become tubular legs that extend rearward from both left and right ends of the rear of the storage case and connect their tips to each other, with both end faces in the vertical direction being open along with the rear, when the display device is used in the tabletop form.

[0008] In this case, an engagement recess is formed at the tip of one of the side covers, and an engagement protrusion that engages with the engagement recess is formed at the tip of the other side cover, and the leg is formed into a triangular tube shape with open end faces in the upper and lower directions by the pair of side covers, with the engagement protrusions engaged with the engagement recesses, and the back surface of the storage case.

[0009] In this case, it is preferable that the lower edge of the side cover is inclined upward as it becomes farther away from the storage case.

[0010] In this case, the side cover has a side body plate connected to the left and right ends of the rear surface of the storage case, and an auxiliary piece connected to a lower part of the tip of the side body plate, the engagement recess and the engagement protrusion are each formed at the tip of the side body plate above the auxiliary piece, the lower edge of the side cover is formed in a straight line from the side body plate to the auxiliary piece, the leg is formed by the pair of side body plates, with the engagement protrusion engaged with the engagement recess, and the rear surface of the storage case, into a triangular tube shape with both end faces in the up and down direction being open, and when the pair of side body plates form the leg, the pair of auxiliary pieces overlap each other by bending relative to the side body plates, and become auxiliary legs protruding rearward from the apex of the triangular leg when viewed from above.

[0011] In this case, an opening cut line is formed on one of the side body plates or the other of the side body plates, running vertically in the up-down direction along the contour of the engagement recess and the auxiliary piece or the contour of the engagement protrusion and the auxiliary piece, and a fixing piece is connected to the side body plate including the opening cut line via the opening cut line, and the exterior part is retained by fixing the fixing piece of the side body plate to the side body plate not including the opening cut line.

[0012] In this case, the display device further includes a top cover connected to the upper end of the back surface of the storage case, and a bottom cover connected to the lower end of the back surface of the storage case, and an opening is formed on the upper surface of the storage case for inserting and removing the item, and the top cover closes the opening and overlaps the upper part of the front surface of the storage case to form a part of the exterior when the display tool is transported or stored, and extends upward from the upper end of the back surface to form a panel when the display tool is used in the hanging form or tabletop form, and the bottom cover covers the lower surface of the storage case when the display tool is transported or stored. and when the display device is used in the hanging form, it overlaps the lower part of the back surface of the storage case to form part of the exterior portion, and when the display device is used in the tabletop form, it overlaps the lower part of the back surface of the storage case to form part of the legs, and the exterior portion is formed by stacking a pair of the side covers on the top cover and the bottom cover which are stacked on the front surface of the storage case, and the reinforcing portion is formed by stacking a pair of the side covers on the bottom cover which is stacked on the back surface of the storage case.

[0013] In this case, the storage case comprises an outer case formed in a rectangular tube having an outer opening on its top surface and a bottom surface, which stores the item in a removable manner, and an inner case formed in a rectangular tube having an inner opening on its top surface and a bottom surface, which stores the item in a removable manner, is inserted into the outer case through the outer opening, and is supported by the outer case so that it can slide in the vertical direction, the inner case is positioned behind the item stored in the outer case, and a support piece is formed on the lower part of the back surface of the outer case, which is cut into a U-shape, leaving one side extending in the vertical direction, and when the display device is used in the hanging form or the tabletop form, the inner case is pulled up to expose the upper part from the outer opening, and the support piece protrudes into the inside of the outer case and interferes with the underside of the pulled up inner case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. Note that Fr, Rr, L, R, U, and D shown in the drawings indicate front, rear, left, right, top, and bottom. The front-back, left-right, and top-bottom directions are mutually orthogonal. Terms indicating directions and positions are used in this specification, but these terms are used for convenience of explanation and do not limit the technical scope of the present invention. In addition, the terms indicating directions and positions are mainly based on the directions and positions of the display tool when it is in use.

[0017] The display tool 1 according to this embodiment will be described with reference to Figs. 1 to 5. Fig. 1 is a perspective view showing the display tool 1 (tabletop form F3). Fig. 2 is a perspective view showing the display tool 1 (hanging form F2). Fig. 3 is a plan view showing the first and second blanks 1A and 1B of the display tool 1. Fig. 4 is a plan view showing the third blank 1C of the display tool 1. Fig. 5 is a plan view showing the fourth blank 1D of the display tool 1.

[0018] The display device 1 is a paper fixture configured to store and display sheet-like items 90, such as pamphlets, flyers, and clear files. As shown in Figs. 1 and 2, the display device 1 is provided with a storage case 2 formed in a rectangular tube shape having a bottom, and which stores the items 90 in a removable manner. The storage case 2 is formed in a roughly thick plate shape, with the front-to-back dimension being narrower than the vertical and horizontal dimensions. The storage case 2 has a nested structure in which an inner case 7 is incorporated into an outer case 6.

[0019] Although details will be described later, the display tool 1 is transported or stored in a transport form F1 in which it is roughly in the shape of a thick plate. The display tool 1 is transformed from the transport form F1 into a hanging form F2 (see FIG. 2) or a tabletop form F3 (see FIG. 1). The display tool 1 is used to display an item 90 in a form selected from the hanging form F2 and the tabletop form F3. The display tool 1 in the hanging form F2 (see FIG. 2) is hung, for example, from a wall or partition of a store where the item 90 is displayed. The display tool 1 in the tabletop form F3 (see FIG. 1) is placed, for example, on a display shelf or a cash register counter installed in a store.

[0020] The display device 1 is formed of, for example, a cardboard sheet made of paper, except for the inner case 7 of the storage case 2. The cardboard sheet is, for example, a double-sided cardboard sheet in which a liner is attached to the front and back of a corrugated core 9A. The inner case 7 is formed of, for example, a multi-layered interleaf paper. Note that Figs. 3 to 5 show the surface H. In this specification, the direction parallel to the core 9A of the cardboard sheet is called the "column direction", and the direction perpendicular to the column direction is called the "flow direction". In the drawings, "X" indicates the "column direction", and "Y" indicates the "flow direction". In addition, the direction parallel to the grain of the interleaf paper is called the "grain direction", and the direction perpendicular to the grain direction is called the "orthogonal direction". In the drawings, "V" indicates the "grain direction", and "W" indicates the "orthogonal direction".

[0021] The display device 1 excluding the inner case 7 is assembled from the first to third blanks 1A to 1C shown in Figures 3 and 4. The inner case 7 is assembled from the fourth blank 1D shown in Figure 5. The first to fourth blanks 1A to 1D are each formed by punching out a single cardboard sheet or interleaf paper using a die or the like.

[0022] [First blank] As shown in the upper part of Fig. 3, the first blank 1A has a front wall 10, a pair of side walls 11, a pair of side joint pieces 12, a first bottom flap 13, and a pair of second bottom flaps 14. The first blank 1A constitutes most of the outer case 6 of the storage case 2, except for the back surface and a part of the bottom surface. In Fig. 3, the pair of side walls 11 are formed symmetrically with respect to the front wall 10, so that in this specification, one side wall 11 will be mainly described. For the same reason, in this specification, one side joint piece 12 and one second bottom flap 14 will be mainly described.

[0023] <Front wall> The front wall 10 is generally formed in a rectangular shape with the long side in the step direction (vertical direction). A square-shaped outer front recess 10A is opened at the upper part of the front wall 10. The outer front recess 10A is cut downward from the upper end of the front wall 10, leaving both sides in the left and right direction of the front wall 10. The vertical dimension (height or depth) of the outer front recess 10A is set to about 1 / 3 of the total height of the front wall 10.

[0024] <Side wall, side joint piece> The pair of side walls 11 are connected to both ends of the front wall 10 in the flow direction (left-right direction) via a first folding line L1. The side wall 11 is formed in a rectangular shape with approximately the same height as the front wall 10. The size of the side wall 11 in the flow direction (width in the front-rear direction) is set to be sufficiently shorter than the size of the front wall 10 in the flow direction (width in the left-right direction) (for example, about 1 / 7). The pair of side joint pieces 12 are connected to both ends (tips) of the pair of side walls 11 in the flow direction (left-right direction) via a second folding line L2. The side joint pieces 12 are approximately the same height as the side wall 11 and are formed in an approximately trapezoidal shape that gradually becomes shorter in the step direction toward the outside in the flow direction. The size of the side joint pieces 12 in the flow direction (width in the left-right direction) is set to be slightly shorter than the size of the side wall 11 in the flow direction.

[0025] <First bottom flap> The first bottom flap 13 is connected to one end (lower end) of the front wall 10 in the step direction via the third fold line L3. The first bottom flap 13 is generally formed in a rectangular shape with approximately the same width in the flow direction as the front wall 10. The dimension of the first bottom flap 13 in the step direction (front-to-back direction) is set to be slightly shorter than the dimension of the side wall 11 in the flow direction (front-to-back direction). A pair of first bottom recesses 13A are recessed at the tip side of the first bottom flap 13 with a gap in the flow direction. A first bottom protrusion 13B is formed between the pair of first bottom recesses 13A so as to protrude relatively.

[0026] <Second bottom flap> The second bottom flap 14 is connected to one end (lower end) of the side wall 11 in the step direction via the third fold line L3. The second bottom flap 14 is formed in a polygonal shape with a corner on the center side in the flow direction cut out into an approximately trapezoidal shape. The dimension of the second bottom flap 14 in the step direction (left and right direction) is the same as the dimension of the first bottom flap 13 in the step direction.

[0027] [Second blank] 3, the second blank 1B has a third bottom flap 15 and a bottom joining piece 16. The second blank 1B forms a part of the bottom surface of the outer case 6 of the storage case 2.

[0028] <Third bottom flap> The third bottom flap 15 is generally formed in a trapezoid shape with approximately the same width in the flow direction (left-right direction) as the first bottom flap 13. The dimension of the third bottom flap 15 in the step direction (front-back direction) is approximately the same as the dimension of the first bottom flap 13 in the step direction. A pair of third bottom convex portions 15A are protrudingly provided at the tip side of the third bottom flap 15 with a gap in the flow direction. A third bottom concave portion 15B is formed between the pair of third bottom convex portions 15A so as to be relatively concave.

[0029] <Bottom joint piece> The bottom joint piece 16 is connected to one end (rear end) of the third bottom flap 15 in the step direction via the fourth fold line L4. The bottom joint piece 16 is formed in a substantially trapezoidal shape that is line-symmetrical about the fourth fold line L4. A pair of relief grooves 16A are recessed in the bottom joint piece 16 at intervals in the flow direction. Each relief groove 16A is cut from the tip of the bottom joint piece 16 to the fourth fold line L4, and the fourth fold line L4 is divided into three by the pair of relief grooves 16A.

[0030] The first to fourth fold lines L1 to L4 are general-purpose creases formed by crushing the cardboard sheet in the thickness direction from the back surface T (back liner side), but are not limited thereto. For example, any structure that folds the cardboard sheet in a desired direction may be used, such as perforations in which cuts and seams are alternately arranged, or lead creases in which perforations are formed on general-purpose creases. In addition, on the surfaces H of the front wall 10 and the side wall 11, for example, letters or pictures such as advertisements for the article 90 are printed (not shown).

[0031] [Third Blank] As shown in Fig. 4, the third blank 1C has a rear wall 17, a pair of side covers 3, a top cover 4, and a bottom cover 5. The rear wall 17 constitutes the rear surface of the outer case 6 of the storage case 2. In Fig. 4, the pair of side covers 3 are formed symmetrically with respect to the rear wall 17, and therefore, in this specification, mainly one side cover 3 will be described.

[0032] <Back wall> The rear wall 17 is formed in a rectangular shape having approximately the same size as the front wall 10 (including the outer front recess 10A). A pair of support pieces 18 are formed at one end (lower part) in the step direction of the rear wall 17 (the rear face of the outer case 6). The pair of support pieces 18 are formed in a rectangular shape that is line-symmetrical with respect to a center line (not shown) that divides the rear wall 17 in half in the flow direction (left-right direction). Each support piece 18 is cut into a U-shape (or C-shape) on the center line side, leaving one side (support fold line L21) extending in the step direction (up-down direction). <Side cover> The pair of side covers 3 extend outward from both ends of the rear wall 17 in the flow direction (left-right direction). The side covers 3 are approximately the same height as the rear wall 17, and are formed in an approximately trapezoidal shape that becomes shorter in the step direction as it moves away from the rear wall 17 outward in the flow direction. One end (lower side 3A) of the side cover 3 in the step direction is inclined toward the other end (upper side) in the step direction as it moves away from the rear wall 17 (housing case 2) outward in the flow direction. The other end (upper side) of the side cover 3 in the step direction is formed in the same straight line (approximately horizontal) as the upper end of the rear wall 17.

[0033] The side cover 3 has a side main plate 20 connected to an end of the rear wall 17 (rear) in the flow direction, and an auxiliary piece 23 connected to one of the flow direction tips of the side main plate 20 (lower part). The side main plate 20 constitutes a main part of the side cover 3, and the auxiliary piece 23 constitutes a lower part on the tip side in the flow direction of the side cover 3. The lower side 3A of the side cover 3 is formed in a straight line from the side main plate 20 to the auxiliary piece 23.

[0034] (Side body plate) The side body plate 20 has a side base plate 21 and a side tip plate 22. The side base plate 21 is connected to the end of the back wall 17 in the flow direction via a fifth fold line L5. The side base plate 21 is formed in a generally trapezoid shape narrow in the flow direction, and its dimension in the flow direction is set to be slightly longer than the dimension in the flow direction of the side wall 11. The side base plate 21 has a side auxiliary fold line L22 formed in a position close to the fifth fold line L5 and parallel to the fifth fold line L5. The side tip plate 22 is connected to the tip of the side base plate 21 in the flow direction via a sixth fold line L6. The side tip plate 22 is formed in a generally trapezoid shape wider in the flow direction than the side base plate 21, and its dimension in the flow direction is set to be about half the dimension in the flow direction of the back wall 17 (or the front wall 10). A double-sided tape 91 is attached near the center of the surface H of the left side tip plate 22 in FIG. 4.

[0035] (auxiliary piece) The auxiliary piece 23 is connected to a lower part of the tip of the side end plate 22 in the flow direction via an auxiliary leg fold line L23. One auxiliary piece 23 (the right one in FIG. 4) is formed in a generally parallelogram shape that inclines toward the other side (upward) in the step direction from the tip of the side end plate 22 in the flow direction outward. The other auxiliary piece 23 (the left one in FIG. 4) is formed in a generally trapezoid shape that becomes shorter in the step direction from the tip of the side end plate 22 in the flow direction outward. The dimension of the auxiliary piece 23 in the flow direction is set shorter than the dimension of the side base end plate 21 in the flow direction.

[0036] (Engagement recess, engagement protrusion) An engagement recess 24 is formed at the end of one side cover 3 (side end plate 22) in the flow direction (right side in FIG. 4), and an engagement protrusion 25 is formed at the end of the other side cover 3 (side end plate 22) in the flow direction (left side in FIG. 4). The engagement recess 24 and the engagement protrusion 25 are each formed in the central region in the step direction (up and down direction), in other words, at the end of the side end plate 22 on the other side (upper side) in the step direction than the auxiliary piece 23. The engagement recess 24 is a substantially trapezoidal recess that becomes longer in the step direction from the tip of the side end plate 22 in the flow direction toward the base end. The engagement protrusion 25 is a substantially trapezoidal protrusion that becomes longer in the step direction from the tip of the side end plate 22 in the flow direction toward the outside. One side of the tip of the engagement protrusion 25 is formed longer in the step direction than one side of the base end of the engagement recess 24. The engaging protrusion 25 has a pair of engaging fold lines L24 that are inclined so as to approach each other from both ends in the step direction of the boundary with the side tip plate 22 toward the outside in the flow direction. A pair of engaging pieces 25A are defined by the pair of engaging fold lines L24 on both sides in the step direction of the engaging protrusion 25. Each engaging piece 25A is formed in a substantially trapezoidal shape that is substantially triangular.

[0037] (Opening cut line) On one (right side in FIG. 4) side body plate 20 (side end plate 22), an opening tear line 26 is formed so as to follow the contours of the engagement recess 24 and the auxiliary piece 23 and to run vertically in the up-down direction. A fixing piece 27 is connected to the side body plate 20 including the opening tear line 26 via the opening tear line 26. That is, in FIG. 4, the right side cover 3 is formed longer in the flow direction than the left side cover 3 by the amount of the fixing piece 27. The opening tear line 26 has, for example, a perforation line formed along the contour of the engagement recess 24 and a zipper formed along the contour of the portion excluding the engagement recess 24.

[0038] <Top cover> The top cover 4 extends outward from the other end (upper end) in the step direction of the rear wall 17. The top cover 4 has a top base end plate 30, a pair of top reinforcing pieces 31, a front panel 32, and a rear panel 33.

[0039] (Top base plate, top reinforcement piece) The top base plate 30 is connected to the other end (upper end) in the step direction of the back wall 17 via the seventh folding line L7. The top base plate 30 is formed in a rectangular shape with approximately the same width in the flow direction as the back wall 17. The dimension in the step direction of the top base plate 30 is approximately the same as the dimension in the flow direction of the side base plate 21. A pair of top reinforcing pieces 31 are connected to both ends in the flow direction of the top base plate 30 via the fifth folding line L5. Each top reinforcing piece 31 is formed in a rectangular shape and is formed longer than the dimension in the flow direction of the side base plate 21. A double-sided tape 91 is attached to the back surface T of each top reinforcing piece 31.

[0040] (Front panel, rear panel) The front panel 32 is connected to the leading end of the top base plate 30 in the step direction via the eighth folding line L8. The rear panel 33 is connected to the leading end of the front panel 32 in the step direction via the panel frame portion 34. The front panel 32 and the rear panel 33 are connected to the panel frame portion 34 via a pair of ninth folding lines L9. The front panel 32 and the rear panel 33 are formed in a substantially rectangular shape that is line-symmetrical with respect to the panel frame portion 34. The front panel 32 and the rear panel 33 have both corners in the flow direction that face each other across the panel frame portion 34 chamfered in an arc shape. The dimension of the front panel 32 and the rear panel 33 in the step direction is set to be longer than the dimension of the top base plate 30 in the step direction. In addition, a pair of insertion holes 94 are formed in the front panel 32 and the rear panel 33 at an interval in the flow direction.

[0041] <Bottom cover> The bottom cover 5 extends outward from one end (lower end) in the step direction of the rear wall 17. The bottom cover 5 has a bottom base end plate 35, a pair of bottom reinforcing pieces 36, and a bottom tip plate 37.

[0042] (Bottom end plate) The bottom base end plate 35 is connected to one end (lower end) in the step direction of the rear wall 17 via a tenth folding line L10. The bottom base end plate 35 has substantially the same shape as the top base end plate 30.

[0043] (Bottom reinforcement piece) The pair of bottom reinforcing pieces 36 are connected to both ends of the bottom base plate 35 in the flow direction via a fifth folding line L5. Each bottom reinforcing piece 36 is formed in a substantially trapezoidal shape that shortens in the step direction as it moves away from the bottom base plate 35 outward in the flow direction. One end (upper side) in the step direction of each bottom reinforcing piece 36 is formed on the same straight line (substantially horizontal) as the tip of the bottom base plate 35. The other end (oblique side 36A) in the step direction of each bottom reinforcing piece 36 is inclined to one side (upward) in the step direction as it moves away from the bottom base plate 35 outward in the flow direction. That is, in FIG. 4, the oblique side 36A of each bottom reinforcing piece 36 is inclined in the opposite direction to the lower side 3A of the side cover 3. The angle β between the oblique side 36A of each bottom reinforcement piece 36 and a virtual line extending from the tenth fold line L10 (see the dotted line in Figure 4) is set to be slightly larger than the angle α between the lower side 3A of the side cover 3 and the virtual line (angle α < angle β).

[0044] (Bottom end plate) The bottom tip plate 37 is connected to the tip of the bottom base end plate 35 in the step direction via an eleventh folding line L11. The bottom tip plate 37 is formed in a rectangular shape that is wider than the bottom base end plate 35 in the step direction.

[0045] The auxiliary leg fold line L23, the engagement fold line L24, and the ninth fold line L9 are general-purpose fold lines, and the side auxiliary fold line L22 and the sixth fold line L6 are lead fold lines. The support fold line L21, the fifth fold line L5, the seventh to eighth fold lines L7 to L8, and the tenth to eleventh fold lines L10 to L11 are reverse fold lines formed by crushing the cardboard sheet in the thickness direction from the front surface H (front liner side). These fold lines are not limited to general fold lines, lead fold lines, and reverse fold lines, and may be any structure that folds the cardboard sheet in a desired direction, such as perforation lines. The front surface H of the front panel 32 is printed with characters or patterns, such as an advertisement for the item 90 (not shown).

[0046] [Fourth blank] As shown in Fig. 5, the fourth blank 1D has an inner front wall 40, an inner back wall 41, a pair of inner side walls 42, an inner bottom wall 43, an insertion piece 44, and a pair of inner pieces 45. The fourth blank 1D constitutes the inner case 7 of the storage case 2. In Fig. 4, the pair of inner side walls 42 are formed symmetrically with respect to the inner front wall 40, so this specification will mainly describe one of the inner side walls 42. For the same reason, this specification will mainly describe one of the inner pieces 45.

[0047] <Inner front wall, inner back wall, inner side wall> The inner front wall 40, the inner back wall 41 and the pair of inner side walls 42 are alternately arranged in a row in the grain direction and are connected via a twelfth fold line L12. The inner front wall 40 has substantially the same shape as the front wall 10 of the first blank 1A. An inner front recess 40A having substantially the same shape as the outer front recess 10A is opened at the other (upper) part of the inner front wall 40 in the perpendicular direction. The inner back wall 41 is formed in a rectangular shape having substantially the same size as the inner front wall 40. A joint piece 46 is connected to one end of the inner back wall 41 in the grain direction via a twelfth fold line L12. The inner side wall 42 is formed in a rectangular shape elongated in the perpendicular direction (front-rear direction). The dimension of the inner side wall 42 in the grain direction is approximately half the dimension of the side wall 11 of the first blank 1A in the flow direction.

[0048] A lock rotation part 47 and a lock piece 48 are formed on one side of the inner back wall 41 in the orthogonal direction (lower part) and in the center in the paper grain direction. The lock rotation part 47 is defined in a rectangular shape by a pair of score lines cut upward from the lower end of the inner back wall 41 and a first lock fold line L25 formed between the upper ends of the pair of score lines. The lock piece 48 is connected to the lower end of the lock rotation part 47 via a second lock fold line L26. The lock piece 48 is formed in a substantially trapezoidal shape that narrows in the paper grain direction as it moves away from the lock rotation part 47 in the orthogonal direction.

[0049] <Inner bottom wall, insert piece, inner piece> The inner bottom wall 43 is connected to one end (lower end) of the inner front wall 40 in the orthogonal direction via the 13th fold line L13. The inner bottom wall 43 is formed in a generally rectangular shape elongated in the grain direction, and the dimension of the inner bottom wall 43 in the orthogonal direction (front-to-back direction) is generally the same as the dimension of the inner side wall 42 in the orthogonal direction. The insertion piece 44 is connected to one end (rear end) of the inner bottom wall 43 in the orthogonal direction via the 14th fold line L14. The insertion piece 44 has a shape generally similar to that of the inner bottom wall 43. A slit-shaped lock hole 49 is drilled in the central area in the grain direction of the boundary line (14th fold line L14) between the inner bottom wall 43 and the insertion piece 44. In addition, a pair of cuts are formed inward from both ends in the grain direction at the boundary line between the inner bottom wall 43 and the insertion piece 44. The inner piece 45 is formed in a substantially square shape, and is connected to one end (lower end) of the inner side wall 42 in the orthogonal direction via a thirteenth fold line L13.

[0050] The twelfth to fourteenth fold lines L12 to L14 and the first and second lock fold lines L25, L26 are each general-purpose creases formed by pressing the surface H of the slip sheet in the thickness direction, but are not limited to these and may be other structures, such as perforations, that fold the slip sheet in a desired direction.

[0051] [Assembly of exhibits] Next, an example of an assembly procedure for the exhibit 1 will be described with reference to Fig. 6 and Fig. 7. Fig. 6 is an exploded perspective view illustrating the procedure for assembling the outer case 6 of the exhibit 1. Fig. 7 is a perspective view illustrating the procedure for housing the inner case 7 in the outer case 6.

[0052] The display tool 1 is assembled by folding the first to fourth blanks 1A to 1D at appropriate positions and gluing them in place. The first to third blanks 1A to 1C have cut marks formed in appropriate positions to indicate the gluing positions, and workers use the cut marks as guides to proceed with the assembly work. Although double-sided tape is preferably used to adhere the first to third blanks 1A to 1C, an adhesive such as hot melt may also be used. In this specification, folding the back surfaces T of the cardboard sheets and the interleaf paper so that they face inward is called a "normal fold," and folding the front surfaces H so that they face inward is called a "reverse fold."

[0053] <Assembly of outer case, etc.> The worker assembles the outer case 6 and the like from the first to third blanks 1A to 1C. As shown in Fig. 6, the worker aligns the lower end (fourth fold line L4) of the bottom joint piece 16 of the second blank 1B with the lower end (tenth fold line L10) of the rear wall 17 of the third blank 1C, and bonds the surface H of the bottom joint piece 16 to the surface H of the rear wall 17. Each support piece 18 of the rear wall 17 is located in each escape groove 16A of the bottom joint piece 16 and is exposed through each escape groove 16A.

[0054] The worker folds the pair of side walls 11 of the first blank 1A along the first folding line L1, and folds the pair of side joining pieces 12 along the second folding line L2. The first blank 1A is folded into a substantially C-shape when viewed from above.

[0055] As shown in Fig. 7, the worker aligns the pair of side walls 11 with both left and right ends (fifth fold line L5) of the rear wall 17, butts the lower ends (oblique sides) of the pair of side joint pieces 12 with both left and right sides (oblique sides) of the bottom joint piece 16, and bonds the surface H of the pair of side joint pieces 12 to the surface H of the rear wall 17. In this state, the first to third blanks 1A to 1C are connected, and the front wall 10, the pair of side walls 11, and the rear wall 17 form a square cylindrical outer case 6 with both upper and lower end faces open. An outer opening 6A is formed on the upper surface of the outer case 6, which is continuous with the outer front recess 10A of the front wall 10 and is used for inserting and removing an article 90.

[0056] The worker folds the first bottom flap 13 of the first blank 1A along the third fold line L3, and then folds the pair of second bottom flaps 14 along the third fold line L3 to overlap the left and right ends of the first bottom flap 13. Next, the worker folds the third bottom flap 15 of the second blank 1B along the fourth fold line L4 to overlap the first bottom flap 13 and each second bottom flaps 14, and while pushing the first bottom flap 13 and each second bottom flaps 14 into the outer case 6, inserts each third bottom convex portion 15A of the third bottom flap 15 into each first bottom concave portion 13A of the first bottom flap 13. Then, the first bottom convex portion 13B of the first bottom flap 13 is inserted into the third bottom concave portion 15B of the third bottom flap 15, and the bottom opening of the outer case 6 is closed (see FIG. 7).

[0057] As a result, the outer case 6 has an outer opening 6A from the top to the front, and is formed into a square tube shape having a bottom. The bottom of the outer case 6 is a so-called interlocking bottom (bottom) formed by engaging the first to third bottom flaps 13 to 15 with each other. The outer case 6 accommodates items 90 so as to be able to enter and leave through the outer opening 6A. In addition, a pair of side covers 3, a top cover 4, and a bottom cover 5 are connected to both the left and right ends, the upper end, and the lower end of the back surface of the outer case 6 (accommodation case 2), respectively.

[0058] As shown in Fig. 6 and Fig. 7 (also refer to Fig. 2 etc. if necessary), the worker folds the back panel 33 and the panel front portion 34 180 degrees forward along a pair of ninth fold lines L9, and adheres the back surface T of the back panel 33 to the back surface T of the front panel 32. The front panel 32 and the back panel 33 constitute a panel main body 38 having a double wall structure. Each insertion hole 94 of the back panel 33 corresponds to each insertion hole 94 of the front panel 32. As shown in Fig. 7, the worker passes a string 92 through a pair of left and right insertion holes 94, ties both ends of the string 92, and hooks an S-shaped metal fitting 93 onto the string 92.

[0059] <Assembly of the inner case> Next, the worker assembles the inner case 7 from the fourth blank 1D. The worker folds the inner back wall 41, each inner side wall 42, and the joint piece 46 of the fourth blank 1D along the twelfth fold line L12, and adheres the front surface H of the joint piece 46 to the back surface T of the inner side wall 42 located opposite the joint piece 46. The inner front wall 40, the pair of inner side walls 42, and the inner back wall 41 form the inner case 7 in the shape of a rectangular tube with both upper and lower end faces open. An inner opening 7A is formed on the top surface of the inner case 7, which is continuous with the inner front recess 40A of the inner front wall 40 and is used for inserting and removing an article 90 (see FIG. 7).

[0060] The worker forwardly folds the inner bottom wall 43 and the insertion piece 44 along the thirteenth and fourteenth fold lines L13 and L14, and inserts the insertion piece 44 into the inner case 7 while closing the bottom opening of the inner case 7 with the inner bottom wall 43. The worker reversely folds the lock rotation part 47 along the first lock fold line L25, and forwardly folds the lock piece 48 along the second lock fold line L26 while inserting it into the lock hole 49. When the lock piece 48 is completely inserted into the lock hole 49, the lock rotation part 47 is unfolded reversely along the first lock fold line L25 to form a part of the inner back wall 41. This restricts the opening of the inner bottom wall 43, and the inner bottom wall 43 is held in a state in which it closes the bottom opening of the inner case 7.

[0061] As a result, the inner case 7 has an inner opening 7A from the top to the front, and is formed into a rectangular tube shape having a bottom surface (see FIG. 7). The inner case 7 accommodates articles 90 so as to be able to enter and leave through the inner opening 7A.

[0062] The worker places the inner case 7 inside the outer case 6 through the outer opening 6A (see the dashed arrow in FIG. 7). The inner case 7 is assembled into the outer case 6 through the outer opening 6A (see FIG. 8 described later) and is supported by the outer case 6 so as to be slidable in the vertical direction. In this manner, in the display device 1 according to the present embodiment, the housing case 2 has a nested structure in which the inner case 7 is assembled into the outer case 6. With the inner case 7 housed in the outer case 6, the lower surface (inner bottom wall 43) of the inner case 7 is in contact with the bottom surface of the outer case 6, and the upper end (the upper opening of the inner opening 7A) of the inner case 7 is approximately aligned with the upper end (the upper opening of the outer opening 6A) of the outer case 6 (see FIG. 8 described later). In this specification, when the outer opening 6A of the outer case 6 and the inner opening 7A of the inner case 7 are collectively described, they will be referred to as the openings 6A and 7A of the housing case 2.

[0063] With the above, the assembly work of the display fixture 1 is completed.

[0064] [Transportation method] The assembled exhibit 1 is transformed into a carrying form F1 for ease of transport or storage. Below, with reference to Figs. 8 to 10, the procedure for transforming the assembled exhibit 1 into the carrying form F1 will be described. Fig. 8 is a perspective view showing a state in which an item 90 is stored in the storage case 2. Fig. 9 is a perspective view showing the process of transforming the exhibit 1 into the carrying form F1. Fig. 10 is a perspective view showing the exhibit 1 (carrying form F1). Note that the string 92 and S-shaped metal fitting 93 are omitted from Figs. 8, 9, and Figs. 11 to 13 and 15 described below.

[0065] As shown in FIG. 8, before the display device 1 is transformed into the transport form F1, an item 90 is stored in the storage case 2 in advance. The outer case 6 and the inner case 7 each store a plurality of items 90, such as a stack of flyers or clear files. The items 90 stored in the outer case 6 and the inner case 7 may be the same type or different types. The inner case 7 is disposed at the rear of the internal space of the outer case 6, and a storage space for the items 90 in the outer case 6 is formed between the front wall 10 and the inner front wall 40. In other words, the inner case 7 is disposed at the rear of the items 90 stored in the outer case 6.

[0066] As shown in Fig. 9, the worker reverse-folds the top base plate 30 along the seventh fold line L7, reverse-folds the pair of top reinforcing pieces 31 along the fifth fold line L5, and reverse-folds the panel main body 38 (front panel 32) along the eighth fold line L8. The top base plate 30 closes the openings 6A, 7A on the top surface of the storage case 2, and each of the top reinforcing pieces 31 overlaps the upper surface H of the side wall 11. The panel main body 38 closes the openings 6A, 7A (external front recess 10A, internal front recess 40A) on the front of the storage case 2, and overlaps the surface H of the front wall 10 remaining on both the left and right sides of the external front recess 10A.

[0067] The worker also reverse-folds the bottom base plate 35 along the tenth fold line L10, reverse-folds the pair of bottom reinforcing pieces 36 along the fifth fold line L5, and reverse-folds the bottom tip plate 37 along the eleventh fold line L11. The bottom base plate 35 overlaps the lower surface of the storage case 2 (surfaces H of the first to third bottom flaps 13 to 15), and each of the bottom reinforcing pieces 36 overlaps the surface H of the lower part of the side wall 11. The bottom tip plate 37 overlaps the surface H of the lower part of the front wall 10.

[0068] The worker also reversely folds each side base plate 21 along the fifth fold line L5, and reversely folds each side tip plate 22 along the sixth fold line L6. At this time, the worker first folds the side body plate 20 (the left side body plate 20) that does not include the opening cut line 26 (see FIG. 9), and then folds the side body plate 20 (the right side body plate 20) that includes the opening cut line 26, and adheres (fixes) the fixing piece 27 to (the back surface T of) the side body plate 20 that does not include the opening cut line 26 (see FIG. 10). Each side base plate 21 overlaps the side wall 11 with the top reinforcing piece 31 and the bottom reinforcing piece 36 sandwiched therebetween. Each side tip plate 22 overlaps the front wall 10 with the panel body 38 and the bottom base plate 35 sandwiched therebetween. The tip sides of the pair of side tip plates 22 overlap each other, and the pair of side tip plates 22 are connected via the fixing piece 27.

[0069] As a result, the display tool 1 is transformed into the transportation form F1 (see FIG. 10). The display tool 1 in the transportation form F1 is formed into a thick plate shape (a rectangular parallelepiped shape that is thin in the front-rear direction) that is slightly larger than the storage case 2. The display tool 1 in the transportation form F1 is delivered to a store that displays the item 90, or stored in a warehouse or the like.

[0070] As shown in FIG. 10, when the display tool 1 is transformed into the transport form F1 (when the display tool 1 is transported or stored), the pair of side covers 3, the top cover 4, and the bottom cover 5 form an exterior part 50 that encases almost the entire storage case 2 except for the back wall 17. The top cover 4 closes the openings 6A, 7A and forms a part of the exterior part 50 by overlapping the upper part of the front wall 10 (the front of the storage case 2), and the bottom cover 5 covers the lower surface of the storage case 2 and forms a part of the exterior part 50 by overlapping the lower part of the front wall 10 (the front of the storage case 2). The pair of side body plates 20 (side covers 3) are stacked on the top cover 4 and the bottom cover 5 that are overlapped on the front of the storage case 2, forming a main part of the exterior part 50 that covers the pair of left and right side surfaces and the front of the storage case 2. The exterior part 50 is held by fixing the fixing pieces 27 of the side body plates 20 to the side body plates 20 that do not include the opening cut line 26. Additionally, each of the side covers 3, top cover 4, and bottom cover 5 constituting the exterior part 50 exposes the back surface T. In other words, when the display device 1 is in the transportation form F1, the back liner (back surface T) of the cardboard sheet is exposed on all sides, front to back, left to right, top to bottom.

[0071] [How to use the exhibits] The display tool 1 is used by being transformed from the carrying form F1 into the hanging form F2 or the tabletop form F3. How to use the display tool 1 will be described with reference to Figs. 1, 2, 11 to 17. Fig. 11 is a perspective view showing the front side of the various covers 3-5 when unfolded. Fig. 12 is a perspective view showing the rear side of the various covers 3-5 when unfolded. Fig. 13 is a perspective view showing the process of transforming the display tool 1 into the tabletop form F3. Fig. 14 is a perspective view showing the rear side of the display tool 1 (tabletop form F3). Fig. 15 is a side view showing the display tool 1 (tabletop form F3). Fig. 16 is a perspective view showing the process of transforming the display tool 1 into the hanging form F2. Fig. 17 is a perspective view showing the rear side of the display tool 1 (hanging form F2).

[0072] <Preparation for use> When using the display device 1 in the hanging form F2 or tabletop form F3, the worker cuts the outermost side cover 3 (fixed piece 27) along the opening cut line 26. The right side body plate 20 is separated from the fixed piece 27, which is left adhered to the left side body plate 20 (see FIG. 12). The worker opens the pair of side covers 3, the top cover 4 and the bottom cover 5 to expose the storage case 2 (excluding the rear wall 17) (see FIG. 11).

[0073] The worker folds the pair of top reinforcing pieces 31 backward along the fifth folding line L5 (forward folding) and attaches them to the back surface T of the top base plate 30 with double-sided tape 91 (see FIG. 12). The pair of top reinforcing pieces 31 reinforce both the left and right sides of the top base plate 30 and hold the top base plate 30 in an upright position. The panel body 38 is erected on the upper end of the top base plate 30. The top base plate 30 and the panel body 38 (top cover 4) are extended upward from the upper end of the rear wall 17 (upper end of the rear surface) to form the panel section 39. In the panel section 39, the surface H of the top base plate 30 and the front panel 32 faces forward, so that advertisements and the like printed on the front panel 32 can be seen from the front of the display device 1.

[0074] As shown in FIG. 11, the worker pulls up the inner case 7 from inside the outer case 6, exposing the upper part of the inner case 7 from the outer opening 6A of the outer case 6. Next, as shown in FIG. 12, the worker pushes the pair of support pieces 18 forward from the back surface. Each support piece 18 is folded back along the support folding line L21, protrudes into the inside of the outer case 6, and interferes with the lower surface of the pulled-up inner case 7 (see FIG. 15). The inner case 7 is placed on the pair of support pieces 18, and each support piece 18 prevents the pulled-up inner case 7 from falling. The storage case 2 has a tiered shape in which the inner case 7 is placed one step higher than the outer case 6 (see FIG. 11). This allows the items 90 exposed from the openings 6A and 7A to be viewed from the front of the display device 1, and the items 90 can be easily removed.

[0075] With the above steps, the preparation for using the display fixture 1 is completed.

[0076] <Tabletop version> A case where the prepared display tool 1 is transformed into the tabletop form F3 will be described. When the display tool 1 is used in the tabletop form F3, as shown in FIG. 13, the worker folds the bottom base end plate 35 (the entire bottom cover 5) backward along the tenth fold line L10 (forward folding). The bottom base end plate 35 and the bottom tip plate 37 overlap the lower part of the back surface T of the rear wall 17, and form part of the back surface of the storage case 2. Each bottom reinforcing piece 36 overlaps the lower part of the back surface T of the side base end plate 21, and form part of the side main body plate 20. The oblique side 36A of each bottom reinforcing piece 36 is at a steeper angle than the lower side 3A of the side main body plate 20 (side base end plate 21), and is therefore located above the lower side 3A.

[0077] The worker reversely folds each of the engagement pieces 25A of the engagement protrusion 25 formed on the left side body plate 20 along the engagement fold line L24, and reversely folds the pair of auxiliary pieces 23 along the auxiliary leg fold line L23. The worker also folds back (forward folds) the pair of side body plates 20 (the entire side cover 3) backward along the fifth fold line L5 (and the side auxiliary fold line L22), and butts the tips of the side body plates 20 together. At this time, as shown in FIG. 14, the worker engages (fits) the engagement protrusion 25 formed by folding the pair of engagement pieces 25A in the reverse into the engagement recess 24 formed on the right side body plate 20, and overlaps the pair of auxiliary pieces 23. After fitting the engagement protrusion 25 into the engagement recess 24, the worker opens each of the engagement pieces 25A folded in the reverse at the engagement fold line L24. This restricts the engagement protrusion 25 engaged with the engagement recess 24 from being pulled out, and the tips of the pair of side body plates 20 are connected to each other.

[0078] As shown in FIG. 14 and FIG. 15, a pair of side body plates 20 (side covers 3) with the engaging protrusions 25 engaged with the engaging recesses 24 and the rear wall 17 (rear of the storage case 2) form a triangular tubular leg 51 with both upper and lower end faces open. (C2, C4) The bottom cover 5 mainly forms a part of the leg 51 by overlapping with the lower part of the rear wall 17 (rear of the storage case 2). The pair of side body plates 20 (side covers 3) form the main part of the leg 51 by extending from both left and right ends of the rear wall 17 toward the rear while approaching each other and connecting their tips. The leg 51 is held in a triangular tubular shape by engaging the engaging protrusions 25 with the engaging recesses 24. When the pair of side body plates 20 form the leg 51, the pair of auxiliary pieces 23 are bent relative to the side body plates 20 to overlap each other, and become auxiliary legs 52 protruding rearward from the apex of the triangular leg 51 when viewed from above.

[0079] As a result, the display tool 1 assumes the tabletop form F3 (see Figs. 1, 14 and 15). The display tool 1 in the tabletop form F3 is placed, for example, on a cash register counter in a store. It is difficult to keep the thick plate-like storage case 2 standing stably on its own, but by connecting the legs 51 to the back of the storage case 2, the display tool 1 can be kept standing stably. In addition, since the lower edge 3A of the side cover 3 that contacts the installation surface of the cash register counter or the like is inclined upward from the back wall 17 toward the rear, the display tool 1 assumes a posture in which it is slightly tilted backward (see Fig. 15). In other words, the storage case 2 assumes a posture in which it is leaned against the legs 51.

[0080] <Hanging form> A case where the prepared display tool 1 is transformed into the hanging form F2 will be described. When using the display tool 1 in the hanging form F2, the worker folds the pair of bottom reinforcing pieces 36 backward (forward folding) along the fifth folding line L5 to overlap the back surface T of the bottom base end plate 35, and then folds the bottom base end plate 35 (the entire bottom cover 5) backward (forward folding) along the tenth folding line L10 (see FIG. 16). The bottom base end plate 35 and the bottom tip plate 37 overlap the lower part of the back surface T of the back wall 17, and form a part of the back surface of the storage case 2. Each bottom reinforcing piece 36 is sandwiched between the back wall 17 and the bottom base end plate 35.

[0081] 16 and 17, the worker folds the left side cover 3 backward along the fifth fold line L5 and the side auxiliary fold line L22 (forward folding) to overlap the back surface T of the rear wall 17, and then folds the right side cover 3 backward along the fifth fold line L5 and the side auxiliary fold line L22 (forward folding) to overlap the back surface T of the rear wall 17 and the front surface H of the left side cover 3. The right side cover 3 is fixed to the left side cover 3 via double-sided tape 91 attached to the front surface H of the left side cover 3.

[0082] As shown in Fig. 17, the pair of side covers 3 and the bottom cover 5 form a reinforcing portion 53 that covers almost the entire rear wall 17. The bottom cover 5 forms part of the reinforcing portion 53 by overlapping the lower part of the rear wall 17 (the rear face of the storage case 2). The pair of side main body plates 20 (side covers 3) form a main part of the reinforcing portion 53 by being laminated to the bottom cover 5 that is overlapped on the rear wall 17 (the rear face of the storage case 2). By fixing the right side cover 3 to the left side cover 3, the reinforcing portion 53, together with the rear wall 17, generally forms a triple-wall structure.

[0083] In this way, the display fixture 1 is in the hanging configuration F2 (see Figs. 2 and 17). The display fixture 1 in the hanging configuration F2 is hung via the string 92 by, for example, hanging the S-shaped metal fitting 93 on a hook (not shown) fixed to the wall of a store or the like. Note that the S-shaped metal fitting 93 may be omitted, and the string 92 may be hung on the hook fixed to the wall or the like. Also, the string 92 may be omitted, and for example, a hook on the wall may be hung on a hole formed in the panel portion 39 of the display fixture 1 (not shown).

[0084] In the above description, the prepared exhibit 1 was transformed into the tabletop form F3, but the present invention is not limited to this, and the exhibit 1 in the tabletop form F3 may be transformed into the hanging form F2. In addition, in the exhibit 1 in the hanging form F2, the pair of side covers 3 are joined with the double-sided tape 91, so the exhibit 1 transformed into the hanging form F2 cannot be transformed into the tabletop form F3.

[0085] In the display tool 1 according to the present embodiment described above, when the display tool 1 is transported or stored (when used in the transport form F1), the pair of side covers 3 and the like are configured to become the exterior part 50 that covers both side surfaces in the left and right direction and the front surface of the storage case 2 (see FIG. 10). According to this configuration, in the display tool 1 in the transport form F1, both side surfaces and the front surface of the storage case 2 are not exposed, so that both side surfaces and the front surface can be protected from scratches and dirt. In addition, in the display tool 1 in the transport form F1, the side covers 3, the top cover 4, and the bottom cover 5 expose the back surface T, so that the surface H of the side covers 3 and the like can be protected from scratches and dirt. As a result, when the display tool 1 is used in the hanging form F2 or the tabletop form F3, the surface H without scratches or dirt can be exposed, so that the cosmetic quality of the display tool 1 can be maintained. In addition, since the storage case 2 is formed in a square tube shape having a bottom surface, the item 90 can be properly held regardless of the form of the display tool 1.

[0086] Furthermore, according to the display tool 1 of this embodiment, when the display tool 1 is used in the hanging form F2, the pair of side covers 3 serve as reinforcing parts 53 that cover the back surface of the storage case 2, thereby reinforcing the back surface of the storage case 2 (see FIG. 17). This makes it possible to suppress distortion of the hanging display tool 1.

[0087] Furthermore, in the display tool 1 according to this embodiment, when the display tool 1 is used in the tabletop form F3, the pair of side covers 3, together with the rear face (rear wall 17) of the storage case 2, form a triangular tubular leg 51 with both upper and lower end faces open (see Figs. 1, 14 and 15). This configuration makes it possible to form a leg 51 that is more resistant to compressive loads than a tubular shape with both left and right end faces open. Also, because the leg 51 has a truss structure that is less likely to deform, the storage case 2 can stand on its own stably.

[0088] Moreover, in the display device 1 according to this embodiment, the tip portions of the pair of side covers 3 are connected by engaging the engaging protrusions 25 with the engaging recesses 24 (see Figs. 14 and 15). With this configuration, the tip portions of the pair of side covers 3 can be connected more easily than when using adhesive tape, adhesives, or the like.

[0089] Furthermore, according to the display tool 1 of this embodiment, the lower edge 3A of the side cover 3 is inclined upward as it moves away from the storage case 2, so that the display tool 1 in the tabletop form F3 can be used in a position tilted slightly backward (see FIG. 15). This makes it easier for customers to see and take out the item 90. Another effect is that the display tool 1 in the tabletop form F3 is less likely to tip forward.

[0090] Furthermore, in the display fixture 1 according to this embodiment, when the pair of side main body plates 20 form the legs 51, the pair of auxiliary pieces 23 overlap to form the auxiliary legs 52, which protrude rearward from the rearmost part of the legs 51 when viewed from above (see Figs. 14 and 15). With this configuration, when the display fixture 1 (tabletop form F3) is tilted backward, the lower end of the auxiliary legs 52 is pressed against the installation surface, so that the tilted display fixture 1 can be firmly supported.

[0091] Furthermore, in the display device 1 according to this embodiment, the right side body plate 20 is formed with an opening cut line 26 that divides the fixed piece 27, and the exterior part 50 is formed by fixing the fixed piece 27 of the right side body plate 20 to the left side body plate 20 (see FIG. 10). With this configuration, the right side body plate 20 can be cut along the opening cut line 26 without using a tool such as a utility knife. This makes it possible to easily transform the display device 1 in the transport form F1 into the hanging form F2 or tabletop form F3.

[0092] Furthermore, according to the display tool 1 of this embodiment, when used in the transport form F1, the top cover 4 closes the openings 6A, 7A of the storage case 2, thereby preventing the item 90 from falling off and preventing foreign objects from entering the storage case 2. When the display tool 1 is used in the hanging form F2 or tabletop form F3, the top cover 4 becomes a panel section 39 that extends upward from the back surface of the storage case 2, and advertisements for the item 90 can be displayed on this panel section 39. Furthermore, when the display tool 1 is used in the transport form F1, the bottom cover 5 covers the bottom surface of the storage case 2, thereby protecting the bottom surface (and the lower part of the front surface) of the storage case 2 from scratches and dirt.

[0093] Moreover, in the display device 1 according to this embodiment, the storage case 2 has a nested structure in which the inner case 7 is incorporated into the outer case 6, and when the display device 1 is used in the hanging form F2 or tabletop form F3, the inner case 7 is pulled up and supported in a state in which the upper part is exposed from the outer opening 6A (see Figs. 1 and 2). With this configuration, the outer case 6 and the inner case 7 form a tiered stand, and the items 90 stored in the outer case 6 and the inner case 7, respectively, can be easily taken out from the front side. Also, for example, different types of items 90 can be stored separately in the outer case 6 and the inner case 7.

[0094] In the display device 1 according to the present embodiment, the storage case 2 has a nested structure in which the inner case 7 is incorporated into the outer case 6, but the present invention is not limited to this. For example, the inner case 7 may be omitted, and the storage case 2 may be composed of only the outer case 6 (not shown).

[0095] In addition, in the display device 1 according to the present embodiment, the inner opening 7A is formed from the top surface of the inner case 7 to the front surface, but the present invention is not limited to this. For example, the inner opening 7A may be formed only on the top surface of the inner case 7, or may be formed only on the front surface (inner front wall 40) of the inner case 7 (neither is shown). Similarly to the above, the outer opening 6A may be formed only on the top surface of the outer case 6 (not shown). Also, when the inner case 7 is omitted, the outer opening 6A may be formed only on the front surface (front wall 10) of the outer case 6 (not shown).

[0096] In addition, in the display device 1 according to this embodiment, the bottom cover 5 has a pair of bottom reinforcing pieces 36, but this is not limiting, and the pair of bottom reinforcing pieces 36 may be omitted (not shown). Since the bottom surface of the storage case 2 (outer case 6) is a part that is difficult to see, the bottom cover 5 may be omitted if scratches and dirt on the bottom surface of the storage case 2 are acceptable.

[0097] In addition, in the display device 1 according to this embodiment, the top cover 4 has a pair of top reinforcing pieces 31, but this is not limiting, and the pair of top reinforcing pieces 31 may be omitted (not shown). In addition, when the inner case 7 is omitted and the outer opening 6A is formed only on the front surface of the outer case 6, the top cover 4 may be omitted (not shown).

[0098] In addition, in the display device 1 according to this embodiment, when used in the transport mode F1, the right side cover 3 (fixing piece 27) is attached to the left side cover 3 via double-sided tape 91, but the present invention is not limited to this. For example, the pair of side covers 3 may be connected to each other by a single-sided adhesive tape, adhesive, clips, or the like (none of which are shown).

[0099] In addition, in the display device 1 according to the present embodiment, the tear line 26 and the fixed piece 27 are formed on the right side cover 3, but the present invention is not limited to this. For example, the tear line 26 and the fixed piece 27 may be formed on the left side cover 3, may be formed on both side covers 3, or may be omitted (none of which are shown).

[0100] In addition, in the display device 1 according to this embodiment, when used in the tabletop form F3, the tip portions of the pair of side covers 3 are connected by the engaging recesses 24 and the engaging protrusions 25, but the present invention is not limited to this. For example, the engaging recesses 24 and the engaging protrusions 25 may be omitted, and the tip portions of the pair of side covers 3 may be connected by an adhesive tape, adhesive, clips, or the like (none of which are shown).

[0101] In addition, in the display device 1 according to the present embodiment, when used in the tabletop form F3, the pair of side covers 3 and the like form the triangular tubular leg 51, but the present invention is not limited to this. For example, the pair of side covers 3 may be bent into an L-shape that is symmetrical when viewed from above, and the pair of side covers 3 and the back wall 17 may form a rectangular tubular leg (not shown). Also, for example, the pair of side covers 3 may be curved so as to be symmetrical when viewed from above, and the pair of side covers 3 and the back wall 17 may form a roughly semicylindrical leg (not shown). In other words, the leg 51 is not limited to a triangular tubular shape, and may be any shape as long as it is a tubular shape with both upper and lower end faces open.

[0102] In addition, in the display tool 1 according to the present embodiment, when used in the hanging form F2, the right side cover 3 is attached to the left side cover 3 via the double-sided tape 91, but the present invention is not limited to this. For example, the pair of side covers 3 may be connected to each other by a single-sided adhesive tape, adhesive, clips, or the like (none of which are shown). If the pair of side covers 3 are connected in a detachable state, such as by a clip, the display tool 1 transformed into the hanging form F2 can be transformed into the tabletop form F3. In addition, the display tool 1 transformed into the hanging form F2 or the tabletop form F3 can be returned to the transport form F1. In addition, the double-sided tape 91 is attached to the surface H of the left side cover 3, but the double-sided tape 91 may be attached to the surface H of the right side cover 3, or may be attached to the surfaces H of both side covers 3 (none of which are shown).

[0103] In addition, in the display tool 1 according to this embodiment, the lower edge 3A of the side cover 3 is inclined upward as it is away from the storage case 2, but this is not limited thereto, and the lower edge 3A may be formed in the same straight line (approximately horizontal) as the lower end of the rear wall 17 (not shown). In this case, the display tool 1 in the tabletop form F3 stands approximately upright on the installation surface (not shown).

[0104] In addition, in the display device 1 according to the present embodiment, the auxiliary piece 23 is connected to the lower part of the tip of the side body plate 20, but this is not limiting, and the auxiliary piece 23 may be omitted (not shown). In other words, the auxiliary leg portion 52 may be omitted (not shown).

[0105] In addition, in the display device 1 according to the present embodiment, the storage case 2 (outer case 6) is constructed by combining the first to third blanks 1A to 1C, but the present invention is not limited to this. For example, the outer case 6 may be assembled from one blank, similar to the inner case 7 (fourth blank 1D), and the back of the outer case 6 may be glued to the back wall 17 of the third blank 1C (not shown). Also, for example, the back wall 17 of the third blank 1C may be omitted, and each side cover 3, top cover 4, and bottom cover 5 may be glued to the back of the outer case 6 having the same structure as the inner case 7 (not shown).

[0106] In addition, in the display device 1 according to the present embodiment, the storage case 2 (outer case 6, inner case 7) is formed in a thick plate shape that is difficult to stand on its own, but this is not limiting and it may be formed in a rectangular parallelepiped shape that is self-supporting (not shown). Also, the item 90 stored in the storage case 2 is formed in a sheet shape, but this is not limiting and items of various shapes (not shown) may be stored in accordance with the shape of the storage case 2.

[0107] In addition, in the display device 1 according to this embodiment, the bottom surface of the outer case 6 is a so-called bottom, but it is not limited to this, and may be, for example, a so-called one-touch bottom, or a structure in which multiple flaps are butted together and fixed with adhesive tape (neither is shown). Also, like the bottom surface of the outer case 6, the structure of the bottom surface of the inner case 7 may be freely changed (not shown).

[0108] In addition, in the display tool 1 according to the present embodiment, the portions excluding the outer case 6, etc. (first to third blanks 1A to 1C) and the inner case 7 are formed from a double-sided corrugated cardboard sheet made of paper, and the inner case 7 is formed from interleaf paper, but the present invention is not limited to this. For example, the outer case 6, etc. may be formed from interleaf paper, and the inner case 7 may be formed from a double-sided corrugated cardboard sheet. Furthermore, the entire display tool 1 may be formed from a double-sided corrugated cardboard sheet or interleaf paper. Furthermore, the dimensions (width, depth, height) and shape of each part of the display tool 1, the thickness of the material, the direction in which the core 9A and the grain extend, etc. may be freely changed.

[0109] The above embodiment is merely an example of the display device of the present invention, and the technical scope of the present invention is not limited to the above embodiment. The present invention may be modified, substituted, or transformed in various ways without departing from the spirit of the technical idea, and the scope of the utility model registration claims includes all embodiments that may be included within the scope of the technical idea.
