Description

[Technical Field]

[0001] The present invention relates to a packaging box. [Background Art]

[0002] Conventionally, a display-combined packaging box has been known, in which a part of the top surface portion or front surface portion of a packaging box is cut out as a display portion forming region, raised upward to be used as a display portion, and articles are displayed while being accommodated in the packaging box, and sales or the like are performed while appealing the articles through the display portion (see Patent Document 1, Patent Document 2 and Patent Document 3).

[0003] In the packaging box of Patent Document 1, a display portion is formed by inserting an opening formed by cutting out a plurality of plate materials including the top surface portion into the box body. In the packaging box of Patent Document 2, an opening and a display portion are formed by cutting out a plurality of plate materials including a part of the top surface portion and bending the same on the top surface portion side. The packaging box of Patent Document 3 discloses a configuration including a front plate that is bent and positioned closer to the front side than the packaging box, and a lid as a display portion that is bent and held in an upright state on the back side of the packaging box.

[0005] In the packaging boxes described in Patent Documents 1 and 3, in particular, in order to fully raise the display portion on the back, the packaging box must be placed on the top shelf of the display unit. Since the display portion cannot be raised on other shelves (regular shelves), a problem arises in that it becomes difficult to appeal to customers while ensuring visibility.

[0006] In the packaging box described in Patent Document 2, the top surface (lid) is used to form the display area. However, the display area is small, limiting the amount of information that can be displayed. Furthermore, because the display area is located on the back side rather than the front edge, it may have poor appeal depending on the shelf position on the display rack.

[0007] Furthermore, in the packaging boxes described in Patent Documents 1 to 3, it was necessary to increase the amount of paper used in the layout in order to create the display area.

[0008] This invention has been made in consideration of the above points, and aims to provide a packaging box that can form a highly appealing display section according to the shelf position on a display rack without increasing the amount of paper used. [Means for solving the problem]

[0012] Hereinafter, embodiments of the packaging box of the present invention will be described with reference to FIGS. 1 to 7. Note that the following embodiment shows one aspect of the present invention, is not intended to limit the present invention, and can be arbitrarily modified within the scope of the technical idea of the present invention. In addition, in the following drawings, in order to make each configuration easy to understand, the scale, number, and the like of each structure are different from those of an actual structure.

[0013] FIG. 1 is an external perspective view of the packaging box 1. As shown in FIG. 1, the packaging box 1 has a rectangular parallelepiped shape. The packaging box 1 includes a top wall 11, a bottom wall 12, and a peripheral wall 2. The peripheral wall 2 is formed by continuously providing a front wall 13, a back wall 14, and a pair of side walls 15, 16. The packaging box 1 has a storage portion 1A surrounded by the peripheral wall 2, the top wall 11 and the bottom wall 12. A content (not shown) is stored in the storage portion 1A. The content is a liquid composition product or a solid product. The content is, for example, a pouch in which a liquid composition or a solid substance is enclosed.

[0014] The packaging box 1 is formed using, for example, cardboard such as manila cardboard, white cardboard, coated cardboard, chipboard, double-sided card paper, back-white cardboard, ivory paper, or corrugated fiberboard.

[0015] The Z-axis direction appropriately shown in each drawing is a vertical direction in which the positive side is defined as "upper side" and the negative side is defined as "lower side"; the side where the top wall 11 is disposed is referred to as the upper side, and the side where the bottom wall 12 is disposed is referred to as the lower side. The Y-axis direction appropriately shown in each drawing is a depth direction in which the positive side is defined as "front side" and the negative side is defined as "back side"; the side where the front wall 13 is disposed is referred to as the front side, and the side where the back wall 14 is disposed is referred to as the back side. The X-axis direction appropriately shown in each drawing is a width direction in which the positive side is defined as "right side" and the negative side is defined as "left side"; the side where the side wall 15 is disposed is referred to as the right side, and the side where the side wall 16 is disposed is referred to as the left side.

[0016] The top wall 11 is arranged on the upper side. The top wall 11 closes the top portion of the peripheral wall 2 in a packaged state. The bottom wall 12 is arranged on the lower side. The bottom wall 12 closes the bottom portion of the peripheral wall 2. The front wall 13 is arranged on the front side. The back wall 14 is arranged on the back side. The side wall 15 is arranged on the right side, extends in the depth direction, and connects the front wall 13 and the back wall 14. The side wall 16 is arranged on the left side, extends in the depth direction, and connects the front wall 13 and the back wall 14.

[0017] The bottom wall 12 is arranged on the lower side. The bottom wall 12 closes the bottom portion of the peripheral wall. As an example, the bottom wall 12 is an auto-bottom shape having a structure in which the bottom surface is bonded with an adhesive.

[0018] Hereinafter, the front wall 13 and the top wall 11 will be mainly described in detail. In FIG. 1, broken lines are indicated by one-dot chain lines, and ruled lines excluding ridge lines are indicated by two-dot chain lines.

[0019] The front wall 13 has a front opening 30. The front opening 30 extends downward from a first ruled line 41 that forms a boundary with the top wall 11. The front opening 30 has a trapezoidal shape in front view that tapers toward the lower side. The vertical position of the lower end of the front opening 30 is above the lower end of the front wall 13. The outer contours on both sides in the width direction and the outer contour at the lower end of the front opening 30 are formed by break lines 30A. When the front opening 30 is cut open along the break lines 30A, an opening 31 (see FIG. 4 and FIG. 6) is formed on the front side by opening the front opening 30 toward the front side centering on the first ruled line 41.

[0020] The top wall 11 closes the top portion of the peripheral wall 2 in a packaged state. The top wall 11 includes a first portion 21, a second portion 22, and an engagement hole 82. The first portion 21 is connected to the back wall 14. When the top wall 11 is opened relative to the pair of side walls 15 and 16, the first portion 21 is movable around a first hinge portion which is the second ruled line 42 serving as a boundary with the back wall 14.

[0021] The first portion 21 includes a first straight portion 21A and a pair of extending walls 21B. The first straight section 21A is located at the rear end of the top wall 11. The first straight section 21A extends along the second ruled line 42 to both ends in the width direction of the top wall 11. The extension walls 21B extend from both ends of the first straight section 21A towards the front side along the width direction side edges of the top wall 11. The front edge of the extension wall 21B is located on the rear side of the first ruled line 41. The front edge of the pair of extension walls 21B is the third ruled line 43, which is the boundary with the second section 22. Therefore, the pair of extension walls 21B extend from both ends of the first straight section 21A towards the front side to the third ruled line 43. Furthermore, the first section 21 is formed by the first straight section 21A and the pair of extension walls 21B in a U-shape that opens to the front side.

[0022] The distance between the second line 42 and the third line 43 is longer than the sum of the distance between the first line 41 and the third line 43 and the distance between the lower end of the front opening 30 and the first line 41. Therefore, when the front opening 30 is opened to the front and the top wall 11 and the front opening 30 are flush on the same plane, the distance between the second line 42 and the third line 43 is longer than the sum of the distance between the third line 43 and the lower end of the front opening 30.

[0023] The second part 22 is connected to the front opening 30 on the front side and to the third crease 43 on the back side. The second part 22 is foldable using the third crease 43 as the second hinge. The second part 22 has a second straight section 22A and a protruding section 22B.

[0024] The second straight section 22A is located at the front end of the top wall 11. The second straight section 22A extends along the first ruled line to both ends in the width direction of the top wall 11, and both ends connect with the third ruled line 43 on the rear side. The protruding section 22B protrudes from the second straight section 22A to the rear side in the depth direction. The protruding section 22B protrudes further to the rear than the position of the third ruled line 43. The protruding section 22B is located between a pair of extending walls 21B in the width direction. The protruding section 22B is in contact with the first section 21 at a U-shaped break line 22C. The protruding section 22B is separated from the first section 21 when it is cut open at the break line 22C.

[0025] The engagement hole 82 is formed in the center of the width direction of the top wall 11, with the second grid line 42 as the boundary. The insertion piece 81, which will be described later, is inserted into the engagement hole 82.

[0026] The second portion 22 and the front opening 30 described above form a display area 50. The display area 50 is formed with a display for identifying the contents. The display for identifying the contents may be, for example, an image or text. The display area 50 includes a first display area 51, a second display area 52, and a third display area 54. The front opening 30 includes the first display area 51 and the second display area 52. The second part 22 includes the third display area 54.

[0027] The first display area 51 is located on the lower end side of the front opening 30 and extends in the width direction. The first display area 51 is the area between the fourth ruled line 44 formed on the lower end side of the front opening 30 and the lower end of the front opening 30. In Figure 1, the letters "ABC" are formed in the first display area 51 as an example to indicate the contents. The front opening 30 has a semicircular insertion piece 81 that protrudes downward from the center in the width direction of the first display area 51.

[0028] The second display area 52 is located above the first display area 51 in the front opening 30. The second display area 52 is located at the upper end of the front opening 30 and extends in the width direction. The second display area 52 is the area between the first line 41 and the fourth line 44 in the front opening 30.

[0029] In Figure 1, the letters "DEF" are formed in the second display area 52, for example, to indicate the contents.

[0030] The third display area 54 is located in the second part 22. In the third display area 54, the letters "GHI" are formed, for example, to indicate the contents. Note that the fourth grid line 44 is not a mandatory feature; a straight line may be printed as a guide for the positions of the first display area 51 and the second display area 52.

[0031] Figure 2 is a plan view showing the blank sheet BL before packaging box 1 is assembled. A blank sheet BL is, for example, made of cardboard primarily composed of paper with resin used in part of its laminated layer structure. That is, a blank sheet BL (packaging box 1) is formed of cardboard with a resin layer. Examples of resins include nylon, polyethylene terephthalate (PET), and polyethylene (PE), but nylon is preferred.

[0032] As shown in Figure 2, the blank sheet BL has a side wall 16, a back wall 14, a side wall 15, a front wall 13, and a seam 17 arranged sequentially from right to left, with grid lines 61, 62, 63, and 64 formed between them. The side wall 16, back wall 14, side wall 15, front wall 13, and seam 17 are folded at the grid lines 61, 62, 63, and 64, respectively, and the seam 17 is joined to the inner surface of the side wall 16, for example with a hot melt adhesive, to form a rectangular tubular peripheral wall 2 that extends in the vertical direction.

[0033] The front wall 13 has a top wall 11 on its upper side via a first crease 41, and an outer flap 12A on its lower side via a fold line 3. The top wall 11 has a joint 18 on its upper side via a second crease 42. The outer flap 12A forms part of the bottom wall 12.

[0034] The side wall 15 has an inner flap 15A on the upper side via a fold line 4A, and an inner flap 12B on the lower side via a fold line 4B. The inner flap 15A is folded along the fold line 4A and attached from below to the right side edge of the top wall 11. The inner flap 12B forms part of the bottom wall 12. The inner flap 12B is attached from below to the right portion of the outer flap 12A with adhesive.

[0035] The rear wall 14 has an outer flap 12C on its lower side via a fold line 5. The outer flap 12C forms part of the bottom wall 12. The rear wall 14 is glued to the joint 18 at its upper edge from the front side.

[0036] The side wall 16 has an inner flap 16A on the upper side via a fold line 6A, and an inner flap 12D on the lower side via a fold line 6B. The inner flap 16A is folded along the fold line 6A and attached from below to the left side edge of the top wall 11. The inner flap 12D forms part of the bottom wall 12. The inner flap 12D is attached from below with adhesive to the left portion of the outer flap 12A. By attaching parts of the outer flaps 12A and 12C to the inner flaps 12B and 12D with adhesive from below, an auto-bottom shaped bottom wall 12 is formed.

[0037] [Display modes for 50 display areas] The packaging box 1 has two display modes depending on how the top wall 11 and the front wall 13 are assembled. That is, the display area 50 can be switched between a first display mode and a second display mode depending on how the top wall 11 and the front wall 13 are assembled. When the display area 50 is to be set to the first display mode or the second display mode, the top wall 11 is cut open along the break line 22C to separate the protruding portion 22B from the first portion 21, and the front wall 13 is cut open along the break line 30A to separate the front opening portion 30 from the front wall 13.

[0038] [First display mode] Figure 3 is a right side view of the packaging box 1 with the display area 50 assembled in the first display mode. As shown in Figure 3, when the display area 50 is in the first display mode, the front opening 30 and the top wall 11 are first moved upwards, centered on the second grid line 42.

[0039] Next, the first display area 51 is folded to the back side at the fourth ruled line 44, which is the boundary with the third display area 54. Then, the first display area 51, which has been folded to the rear side, is placed on top of the inner flap 15A of the side wall 15 and the inner flap 16A of the side wall 16, and the second display area 52 is positioned on top of the front wall 13.

[0040] Figure 4 is a front view of the packaging box 1 with the display area 50 assembled in the first display mode. As shown in Figure 4, by positioning the second display area 52 above the front wall 13, an opening 31 is formed in the front wall 13 that opens to the front side in the shape of the outer contour of the front opening 30. Also, as shown in Figure 3, the second display area 52 is supported from the rear side on the front side of the top wall 11 including the second portion 22, and is approximately parallel to the front wall 13 at the rear side of the opening 31's most forward position. In other words, when the contents of the product are stored in the storage section 1A, the second display area 52, located above the position where the product is most exposed on the front side, has improved visibility even in a small space, making it possible to display information to promote the product.

[0041] Furthermore, at this time, the front wall 13 is blocking the opening 31 below and on both sides in the width direction compared to the front opening 30 before it is cut open at the most front position, thus preventing the goods stored in the storage section 1A from being discharged through the opening 31.

[0042] [Second display mode] Figure 5 is a right side view of the packaging box 1 with the display area 50 assembled in the second display mode. As shown in Figure 5, when the display area 50 is in the second display mode, the front opening 30 is first moved upward, and opened around the second grid line 42, moving it to the furthest back side together with the top wall 11, so that the first portion 21, including the pair of extension walls 21B, is raised to be almost flush with the back wall 14.

[0043] Figure 6 is a front view of the packaging box 1 with the display area 50 assembled in the second display mode. As shown in Figure 6, the first portion 21, which includes a pair of extension walls 21B, is raised to be substantially flush with the back wall 14. Then, the second portion 22 is folded along the third scribe line 43, so that the first display area 51, the second display area 52, and the third display area 54 are aligned substantially flush at the back end and facing the front. At this time, by inserting and engaging the insertion piece 81 into the engagement hole 82, the state in which the first display area 51, the second display area 52, and the third display area 54 are substantially flush at the back end can be maintained. In other words, when the contents of the product are stored in the storage section 1A, the display area 50 can display the product in a way that is large enough to appeal to customers, even with a small amount of space, by extending vertically across the first display area 51, the second display area 52, and the third display area 54.

[0044] Furthermore, because the distance between the second line 42 and the third line 43 is longer than the sum of the distance between the third line 43 and the lower end of the front opening 30, even when the first display area 51, the second display area 52, and the third display area 54 are aligned almost flush at the rear end, the lower end of the first display area 51 is located above the housing area 1A. Therefore, interference between the display area 50 and the products stored in the storage unit 1A can be suppressed.

[0045] As described above, in the packaging box 1 of this embodiment, when the contents that will become the product are stored in the storage section 1A, the display area 50 can be switched between a first display mode in which the second display area 52 is located near the frontmost position of the opening 31 above the position where the product is most exposed on the front side, and a second display mode in which the first display area 51, the second display area 52, and the third display area 54 are aligned substantially flush at the rear end and facing the front side. Therefore, when the packaging box 1 is placed on the top shelf of the display shelf, the second display mode can be selected, and when the packaging box 1 is placed on another shelf, the first display mode can be selected, making it possible to form a highly appealing display area according to the shelf position on the display shelf.

[0046] Furthermore, in the packaging box 1 of this embodiment, when the second display mode is selected, even with a small layout, the product can be displayed across the vertical length spanning the first display area 51, the second display area 52, and the third display area 54 without increasing the amount of paper used, thereby making the product more prominently visible.

[0047] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these examples. The shapes and combinations of the constituent members shown in the above examples are merely examples, and can be modified in various ways based on design requirements, etc., without departing from the spirit of the present invention.

[0048] For example, in the above embodiment, the projection 22B is positioned between a pair of extension walls 21B in the width direction and between the first straight section 21A and the second straight section 22A in the depth direction, but the configuration is not limited to this. For example, by positioning the extension wall 21B of the first portion 21 in the center in the width direction and positioning the protrusions 22B of the second portion 22 on both sides of the extension wall 21B in the width direction, two third display regions 54 extending vertically and spaced apart in the width direction can be formed, as shown in the modified example in Figure 7. When this configuration is adopted, for example, it becomes possible to create a display area 50 that is excellent for vertical writing. [Explanation of Symbols]
