Description

  The present invention relates to a display / cardboard box sheet and a display / cardboard box.

  A cardboard box for transporting goods is used as a container for collectively storing a plurality of goods from transportation of goods to display. Such a cardboard box for transporting goods is opened after transport, and the packaged goods are taken out from the cardboard box. The taken products are displayed on display shelves and cases for sale. In order to simplify the product display operation including taking out the products from the cardboard boxes and displaying them on the shelves and cases, a display and cardboard box in which the cardboard boxes packed with products can be used as they are as a display case is proposed. (See JP-A-10-51150). This display / cardboard box can be opened from a packaged state to a displayed state by breaking along a breaking guide line for opening provided in the rectangular tubular portion.

  However, in the display and cardboard box as described above, even in the display state, a plurality of products are not changed in particular from the arrangement in the packing state, and the products in the packing state are opened to the viewer who is the purchaser. It just gives the impression that it is being done.

  Furthermore, since the plurality of products in the display state are the same as the arrangement in the packing state as described above, it is difficult for the purchaser to pick up the product because other products interfere with the removal of only one product. In other words, for example, when the display starts, a plurality of products are stored in a display box (opened cardboard box) in the same manner as in the packaged state. It is difficult to extract only one product from

  The display / corrugated cardboard box sheet can be assembled into a box shape so that the product can be packed inside, and the product can be opened from the packaged state by breaking along the breaking guide line for opening. Can do. In this opened state, the product receiving recess can be formed by breaking along the recess forming break guide line of the opened piece, and the product can be displayed in a state in which the product is stored in the product receiving recess. In particular, it is possible to display the product in the product receiving recess as if it is popped out from other products by tilting the open piece forward and folding the open end of the open piece back to the rear. it can. For this reason, unlike a display using a conventional cardboard box for display, the product can be displayed three-dimensionally in the front-rear direction, and the viewer can easily view the product. In addition, since the product can be displayed in the product receiving recess positioned forward as described above, the purchaser or the like can easily and reliably hold the product by gripping the product stored in the product storing recess. Can be taken.

  It is preferable that the opening piece has an easy-to-bend line substantially parallel to the lower edge of the front plate on the lower edge side of the front plate with respect to the recess-forming breakage guide line. Thereby, by folding the opening piece along this easy folding line, the free end side of the opening piece can be easily and reliably folded back as described above.

  The second break guide wire may have an intermediate portion extending to the rear plate. Thereby, at the time of opening, the square tubular portion is broken at the middle portion of the second break guide wire, and the opened state from the packed state by breaking from the broken portion toward the front side along the break guide wire for opening. Can be. The opening portion of the top surface obtained in this way is wide in the front-rear direction, so that the product accommodated in the rectangular cylindrical portion other than the opening piece can be easily taken out from the opening portion of the top surface.

[First embodiment]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. First, the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  The display / cardboard box 1 shown in FIG. 2 (hereinafter sometimes simply referred to as “cardboard box”) has the single display / cardboard box sheet 4 (hereinafter also referred to as “cardboard box sheet”) shown in FIG. It is assembled in a box shape.

  The corrugated cardboard box sheet 4 includes a rectangular tubular portion 5 having a top plate 7 and a bottom plate 9 facing each other and a pair of front plates 10 and a rear plate 8 facing each other, and each side edge of the top plate 7 and the bottom plate 9. Two pairs of outer flaps 11 extending from the two sides, and two pairs of inner flaps 12 extending from the side edges of the front plate 10 and the rear plate 8. The rectangular tubular portion 5 further has a paste margin plate 6. Specifically, the rectangular tubular portion 5 is configured by connecting a glue margin plate 6, a top plate 7, a rear plate 8, a bottom plate 9, and a front plate 10 in this order in a straight line. In addition, the bendable line 5a which makes it easy to bend is formed between each board which comprises the square cylindrical part 5, and between this board and a flap.

  The cardboard box sheet 4 is formed in a rectangular parallelepiped shape in a sealed state (state of the cardboard box 1 assembled in a box shape), and is formed using a single cardboard sheet having a uniform thickness. The size of the cardboard box 1 is not particularly limited, and is set as appropriate in consideration of the size of the product as the contents.

  The top plate 7 and the bottom plate 9 have a rectangular shape of the same type and the same size. The front plate 10 and the rear plate 8 also have the same shape and the same rectangular shape. Further, the top plate 7, the bottom plate 9, the front plate 10, and the rear plate 8 have the same length (width) in one direction, and the rectangular cylindrical portion 5 having a rectangular parallelepiped shape is formed by these face plates. The length of the top plate 7 and the bottom plate 9 (the length in the depth direction in the box state) and the length of the front plate 10 and the bottom plate 9 (the length in the vertical direction in the box state) are substantially the same. For this reason, the side wall surface of the cardboard box 1 is provided in a substantially square shape.

  A rear plate 8 is connected to the rear end edge of the top plate 7, and an adhesive margin plate 6 is connected to the front end edge. The bottom plate 9 has a rear plate 8 connected to a rear edge and a front plate 10 connected to a front edge. The corrugated cardboard box sheet 4 has a rectangular shape by bonding (adhering) the adhesive margin plate 6 to the front plate 10 so that the front plate 10 and the top plate 7 connected only to the bottom plate 9 are connected. The cylindrical part 5 can be fixed in a cylindrical shape. In the illustrated example, the adhesive margin plate 6 is joined to the front surface (outer surface) of the front plate 10.

  The glue margin plate 6 has a substantially rectangular shape. The width of the adhesive margin plate 6 (the length in the one direction) is substantially equal to the width of the top plate 7 or the like. Further, the length of the adhesive margin plate 6 (the length in the direction orthogonal to the one direction) is smaller than the length of the front plate 10 and the rear plate 8, for example, 0.2 times or more and 0.4 times or less. It is done.

  In the corrugated cardboard box sheet 4, after forming the rectangular tubular portion 5, the two pairs of inner flaps 12 are folded toward the inside of the rectangular tubular portion 5 at a substantially right angle, and the two pairs of outer flaps 11 are folded into the inner flap 12. The two opposing wall surfaces can be formed by folding the rectangular cylindrical part 5 toward each other at a substantially right angle so as to overlap each other. At this time, by bonding the inner surface of the outer flap 11 to the outer surface of the inner flap 12 with an adhesive or the like, the side wall surface is fixed, and the packaging state of the cardboard box 1 is completed.

  Each of the flaps has a rectangular shape of the same shape and the same size. The length of the outer flap 11 in the vertical direction (the width extending from the rectangular tubular portion 5) is the length of the inner flap 12 in the vertical direction (the circumferential direction of the rectangular tubular portion 5 (the vertical direction on the paper surface of FIG. 1). ), And the edges of the outer flaps 11 are abutted to each other so that no gap is generated. The length in the depth direction of the inner flap 12 (the width extending from the rectangular tubular portion 5) is substantially half the length in the depth direction of the outer flap 11 (the length in the circumferential direction of the rectangular tubular portion 5). In the box state, the end edges of the inner flaps 12 are abutted so as not to generate a substantial gap.

  The procedure for packing the product using the cardboard box sheet 4 can be as follows, for example. First, after placing the product to be packed on the bottom plate 9 in the unfolded state, each plate of the rectangular tubular portion 5 is bent and the glue plate 6 is bonded to the front plate 10 to surround the product. The cylindrical part 5 is formed. Next, by folding the inner flap 12 and the outer flap 11 as described above to form the side wall surface, the packaging of the product in the cardboard box 1 is completed.

  Corrugated cardboard sheets constituting the corrugated cardboard sheet 4 include a core formed in a corrugated shape, a front liner and a back surface layered on the surface side of the core from the viewpoint of high strength and ease of processing and molding. Double-sided cardboard is used that has a back liner laminated to the back. The circumferential direction of the rectangular tubular portion 5 and the corrugated direction of the corrugated cardboard sheet (the direction along the center ridge line) are arranged in parallel.

  The rectangular tubular portion 5 has a breaking guide wire 20 for opening that can be opened from a packed state to a display state. The opening break guide wire 20 includes a pair of first break guide wires 21 provided on the front plate 10 and one second break guide wire 25 provided on the top plate 7. In addition, the said 1st fracture | rupture induction | guidance | derivation line 21 is formed also in the paste margin board 6 joined to the front board 10 in the same location (location overlapped in a box state). The second break guide wire 25 is formed not only on the top plate 7 but also on the rear plate 8, that is, the second break guide wire 25 has an intermediate portion 28 extending to the rear plate 8. . For this reason, when the corrugated cardboard box 1 is broken along the breaking guide line 20 for opening, the unsealed piece 2 (the region partitioned by the breaking guide line before the break) opened by this break is Part of the face plate 10, the top plate 7 and the rear plate 8 is included.

  The first break guide wire 21 has a start point on the bottom side of the front plate 10 and an end point at a site where it is connected to the top plate 7. The starting point of the first break guide line 21 is a connecting portion of the front plate 10 with the bottom plate 9. That is, the first break guide line 21 is formed from the lower end edge to the upper end edge of the front plate 10.

  The pair of first break guide wires 21 are formed in a symmetrical shape. The first break guide wire 21 is formed in the vertical direction with a distance from the side edge of the front plate 10. Here, the first break guide line 21 is provided so as to be inclined from the lower side to the upper side of the front plate 10 so as to approach the adjacent side edge. That is, the pair of first break guide wires 21 are provided so that the distance between them increases as it goes upward.

  More specifically, the first break guide line 21 is continuous with the inclined portion 22 inclined so as to approach the side edge of the front plate 10 that is approached upward from the start point or the end point, and the inclined portion 22. And a vertical portion 23 substantially parallel to the side edge of the front plate 10. Here, the vertical portion 23 is provided in a portion where the front plate 10 and the glue plate 6 are overlapped. In other words, the inclined portion 22 is formed only on the front plate 10, and the vertical portion 23 is formed on both the front plate 10 and the adhesive margin plate 6.

  Further, the front plate 10 is provided with an easy-to-bend line 24 at the position of the end edge (the free end in the unfolded state) of the glue margin plate 6 to be overlaid. It is formed between one break guide wire 21. That is, the easy-to-bend line 24 is formed between the continuous part of the inclined part 22 and the vertical part 23 of the pair of first break guide lines 21.

  In addition, the space | interval of the side edge of the front plate 10 in the upper end edge of the front plate 10 and the 1st fracture induction line 21 can be 0.05 times or more and 0.2 times or less of the width | variety of the front plate 10. FIG. In addition, the distance between the side edge of the front plate 10 and the first break guide line 21 at the lower end edge of the front plate 10 can be 0.1 to 0.3 times the width of the front plate 10.

  The second break guide line 25 has a start point and an end point at the same location as the end point of the pair of first break guide lines 21. The second break guide line 25 is continuous with the start point 26 and the end point 27 extending from the start point and the end point toward the rear wall of the top plate 7 and the start point 26 and the end point 27 as described above. And an intermediate portion 28 provided on the rear plate 8. The starting point portion 26 and the ending point portion 27 are formed in a left-right symmetrical shape, and the intermediate portion 28 is formed substantially at the center in the left-right direction of the rear wall.

  The start point portion 26 and the end point portion 27 as a whole have a substantially inverted U shape in plan view. The start point 26 and the end point 27 are parallel parts 26a, 27a extending from the start point and the end point substantially parallel to the side edge of the top plate 7, and are continuous from the parallel parts 26a, 27a, and are centered in the left-right direction as it goes backward And focusing portions 26b and 27b that are inclined toward the center and continue to the intermediate portion 28. For this reason, the second break guide wire 25 is provided with a distance from the side edge of the top plate 7.

  Further, the intermediate portion 28 of the second break guide wire 25 has a substantially semicircular shape. The width (diameter of the semicircle) of the intermediate portion 28 can be set to 3 cm or more and 10 cm or less, for example. An area defined by the intermediate portion 28 (a tongue piece 2b described later) is separated from an area defined by the converging portions 26b and 27b of the start point portion 26 and the end point portion 27 (the lower side on the paper surface of FIG. 1). B) It is formed in a protruding shape. That is, the opening piece 2 has a tongue piece portion 2b that protrudes toward the free end when it is cut along the second break guide line 25.

  In the corrugated cardboard box sheet 4, an opening piece 2 (part of the front plate 10, the top plate 7, and the rear plate 8) defined by the opening break guide wire 20 forms a product accommodating recess 2 a. A recess-forming breakage guide wire 30 is provided. The recess-forming breakage guide wire 30 is formed on the free end side (tongue piece 2b side) of the opening piece 2 from the base side (the start point side of the first breakage guide line 22), specifically, the top plate 7 Is formed. The recess-forming breakage guide wire 30 is formed in a region sandwiched between the pair of second breakage guide wires 25. For this reason, the folding easy line 24 of the front plate 10 is provided on the lower edge side of the front plate 10 with respect to the recess forming break guide line 30 and substantially parallel to the lower edge of the front plate 10.

  The recess-forming breakage guide wire 30 has a symmetrical shape, and has a substantially I-shape as a whole. Specifically, the recess-forming breakage guide line 30 has a center line formed in the front-rear direction and a pair of left and right lines extending in the left-right direction from the front end and the rear end of the center line. Yes. In addition, a pair of recess-forming folding easy lines 31 connecting the left and right ends of the left and right lines of the recess-forming breakage guide wire 30 is formed.

  In addition, although the fracture | rupture induction | guidance | derivation line was illustrated in the broken line in FIG. 1 (it is the same also in FIG.4 and FIG.6 mentioned later), especially if each fracture | rupture induction | guidance | derivation line is given the process which makes a fracture | rupture easy. It is not limited, For example, it can form by perforation processing and / or half cut processing. In addition, although the easy folding lines are shown as thin lines in FIG. 1 (the same applies to FIGS. 4 and 6 to be described later), each folding easy line is particularly suitable if it has been processed to facilitate folding. It is not limited, For example, it can form by ruled line processing, perforation processing, etc. The perforation process is to form cut parts (perforations) that penetrate from the front surface to the back surface of the corrugated cardboard sheet at regular intervals, and the half cut process cuts one of the liners constituting the corrugated cardboard sheet. The ruled line processing is processing for forming a stepped portion on the corrugated cardboard sheet.

  The cardboard box 1 configured as described above is transported to a store or the like after a plurality of products are packed as described above. The corrugated cardboard box 1 can be opened by breaking along the breaking guide line 20 for opening. Also, the product receiving recess 2a is formed by breaking along the recess forming break guide line 30 of the opening piece 2, and one packaged product is displayed in a state of being stored in the product receiving recess 2a. can do. For this reason, it is possible to display the product three-dimensionally in the front-rear direction, which is different from that in which the product is displayed using the conventional display / cardboard box 1, and it is easy for the purchaser to visually recognize the product. In addition, since the product can be displayed in the product accommodating recess 2a as described above, the purchaser can easily and reliably take the product by gripping the product stored in the product storing recess 2a. it can.

  When storing the product in the product receiving recess 2a, the opening piece 2 is tilted forward, and the free end side of the opening piece 2 is folded back so that the product in the product storing recess 2a It can be displayed in a state of popping out from the product. At the time of folding, the unsealed piece 2 can be easily folded by the folding easy line 24 of the front plate 10.

  Further, the unsealed piece 2 is folded three-dimensionally by being bent by the bendable line 24 of the front plate 10 and the bendable line 5a of the adhesive margin plate 6 and the top plate 7. That is, since the unsealed piece 2 has a plurality of (two) foldable lines, the folded state is three-dimensional. Since the product is stored in the product storing recess 2a on the upper surface of the unsealed piece 2 folded three-dimensionally in this manner, the stability of the stored state of the product is excellent.

  Furthermore, since one of the two easy-to-bend lines to be folded uses the easy-to-bend line 5a between the glue margin plate 6 and the top plate 7, there is no need to newly form a separate easy-to-bend line. In addition, since the other foldable line 24 of the two foldable lines is provided at a portion of the front panel 10 that is not joined to the adhesive margin plate 6, the front panel 10 has a single-sheet structure, and therefore can be easily folded. And it can be done reliably.

  Furthermore, when the above-mentioned opening piece 2 is tilted forward, the opening end of the opening breaking guide wire 20 is provided at the lower edge of the front plate 10, so that the opening piece 2 is attached to the front plate 10 and the bottom plate 9. It can be easily and reliably tilted forward via the easy folding line 5a. That is, since the corrugated cardboard box sheet 4 has an easy-bending line that connects the start and end of the opening break guide wire 20, the opening piece 2 can be easily and surely tilted forward. Further, as such an easy folding line, the easy folding line 5a between the whole and the bottom plate 9 is used as described above, so that it is not necessary to newly form a separate easy folding line.

  Further, since the easy folding line 24 of the front plate 10 is provided at the position of the edge (the free end in the unfolded state) of the glue margin plate 6 to be overlaid, it is folded three-dimensionally as described above. Since the rising portion of the unsealing piece 2 has a laminated structure of the front plate 10 and the paste margin plate 6, the strength of the three-dimensional unsealing piece 2 is excellent. The rising portion of the unsealed piece 2 can be used for a product advertisement or the like by sticking a desired sheet. It is also possible to print a product advertisement in advance on the rising portion of the unsealed piece 2 (the outer surface of the adhesive sheet 6).

  Furthermore, since the opening end of the opening breaking guide wire 20 is provided at the lower end edge of the front plate 10, the opening portion of the cardboard box 1 can be widened in the vertical direction on the front side.

  Furthermore, since the opening piece 2 has the tongue piece portion 2b protruding to the free end side, the region 2b is formed from the region (the rear plate 8) partitioned by the intermediate portion 28 of the opening breaking guide wire 20 to constitute the tongue piece portion 2b. Breaking can be started easily and reliably. Further, since the intermediate portion 28 is provided on the rear plate 8, the opening portion of the top surface is wide in the front-rear direction, so that the products accommodated in the rectangular tubular portion 5 other than the opening piece 2 are also open to the top surface. Can be easily removed from the part.

  Since the pair of first break guide lines 21 are formed with a distance from the side edge of the front plate 10, both sides of the front plate 10 remain on the side of the rectangular tubular portion 5 other than the unsealed piece 2 in the opened state. It will be. For this reason, even if another display / cardboard box 1 is stacked on the display / cardboard box 1 in the opened state, the front plate 10 remaining on the side of the rectangular tubular portion 5 other than the opening piece 2 as described above. A sufficient strength can be obtained by the both side portions of the. In addition, since the second break guide line 25 is formed with a distance from the side edge of the top plate 7, both sides of the top plate 7 remain on the square cylindrical side other than the opening piece 2 in the opened state. Therefore, it is possible to stably place another display and cardboard box 1 placed above.

  The second break guide line 25 has a start point and an end point at the same position as the end point of the first break guide line 21, and extends from the start point and the end point toward the rear wall on the top plate 7. The start point portion 26 and the end point portion 27 are provided so as to be inclined toward the center in the left-right direction toward the rear so as to be continuous with the intermediate portion 28. In addition, the said 2nd fracture | rupture induction | guidance | derivation line 25 is formed also in the paste margin board 6 joined to the top | upper surface board 7 in the same location (location overlapped in a box state).

  In the second embodiment, similarly to the first embodiment, the unsealing piece 2 has a recess-forming breakage guide wire 30, and the recess-forming breakage guide wire 30 is a free end from the base side of the unsealing piece 2. Formed on the side. In the second embodiment, the recess forming break guide wire 30 is formed on the front plate 10. The recess-forming breakage guide wire 30 is provided above the center of the front plate 10 in the vertical direction. An easy-to-bend line 24 that is substantially parallel to the lower edge of the front plate 10 is provided on the lower edge side of the front plate 10 with respect to the recess forming break guide line 30. The unsealed piece 2 is folded back by being bent by the folding easy line 24. Since the product accommodating recess 2a is located at the rising portion (the upper portion of the front plate 10) of the unfolded piece 2 folded in this manner, the product is projected in a form that protrudes forward from the product accommodating recess 2a. Can be accommodated.

  Further, the opening piece 2 is formed with another easy-to-bend line 33 on the back side of the top plate 7. This easy-to-bend line 33 is provided substantially parallel to the front edge of the top plate 7. This easy-to-bend line can be bent near the free end of the folded open piece 2 so that the vicinity of the free end of the open piece 2 can be flattened, and other products can be placed on the flattened portion. Thus, it is possible to stably maintain the state of the unsealed piece 2 containing the product in the product containing recess 2a.

  Further, in the second embodiment, the length of the top plate 7 and the bottom plate 9 (the length in the depth direction in the box state) is the length of the front plate 10 and the bottom plate 9 (the vertical length in the box state). ) Longer. The two pairs of inner flaps 12 have the same shape and the same size of the rectangular shape as in the first embodiment. On the other hand, the two pairs of outer flaps 11 are different in shape between a pair extending from the top plate 7 and a pair extending from the bottom plate 9.
