Description

Technical Field

[0001] This invention relates to a packaging box. The invention also relates to a template for creating (assembling) the packaging box.

Background Art

[0002] Round rice cakes, toys, sundries, and other goods may be displayed in stores in a state of being stored in cardboard packaging boxes. In order to make the goods inside the packaging box visible from the outside, a packaging box having a window covered with a transparent plastic plate on the upper surface or the front surface of the packaging box is also used.

[0003] Patent Document 1 discloses a packaging box for round rice cakes. This packaging box is in the shape of a rectangular parallelepiped, and the stored round rice cake set is taken out of the packaging box and decorated. This packaging box for round rice cakes is made of cardboard, and the opening on the side serves as the entrance and exit for the round rice cakes. The opening on the side is closed by bending a lid panel formed continuously from the bottom surface of the packaging box at a right angle and standing it up. The side surface of the packaging box is used for taking in and out the round rice cakes from the packaging box. However, particularly in a packaging box for round rice cakes that stores a relatively large-sized round rice cake set, the size of the lid panel becomes large, and large gaps are formed on both left and right sides thereof. Therefore, by sticking an adhesive seal to both sides of the lid panel, it is possible to prevent the lid panel from accidentally opening during transportation or display and to prevent foreign matter from entering the packaging box. When the lid panel is closed with an adhesive seal, generally, the consumer cannot open the lid panel neatly and take out the round rice cake set from the packaging box unless the adhesive seal is peeled off or cut with a cutter or the like.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The purpose of this invention is to enable opening and closing of an opening and closing surface without removing the seal, even if the opening and closing surface is closed by a seal.

[0006] The packaging box according to this invention is a packaging box formed into a rectangular parallelepiped shape by folding a single sheet of cardboard, wherein one of the four side surfaces of the packaging box is an entrance / exit for the contents, and this entrance / exit is closed by an opening / closing surface which is one of the side surfaces that is continuous with the bottom surface or top surface and folded at a right angle, and a part of at least one of the left or right sides of the opening / closing surface is fixed to the other surface by a sealing member, and the adhesive area of ​​the sealing member on the opening / closing surface is surrounded by the side edge of the opening / closing surface and a break line formed on the opening / closing surface.

[0007] Adhesive tape is typically used as the sealing component. By applying adhesive tape from the opening / closing surface to the adjacent side surface, the opening / closing surface is fixed to the adjacent side surface, and the gap at the side edge of the opening / closing surface is closed.

[0008] The sealing member may be an emulsion-type adhesive or a hot-melt adhesive. In this case, the adhesive area of ​​the opening / closing surface and other surfaces located on the back (inside) side of the opening / closing surface are bonded together by the adhesive. For the surface located on the back side of the opening / closing surface, a flap that is continuous with the side surfaces (front and rear) adjacent to the opening / closing surface can be used.

[0009] According to this invention, since the adhesive area is enclosed by the side edge of the opening / closing surface and the break line formed on the opening / closing surface, the adhesive area can be cut out from the opening / closing surface along the break line, and the opening / closing surface can be opened while leaving the adhesive area intact (by rotating the opening / closing surface around the boundary with the bottom or top surface to which it is continuous). Since the adhesive area is a part of the opening / closing surface that is continuous with the bottom or top surface, it is not continuous with the adjacent side surface, and therefore its orientation can be freely changed, and it does not keep the entrance / exit closed. The opening / closing surface can be opened without peeling off the sealing member or peeling off the adhesive on the sealing member.

[0010] In one embodiment, the opening and closing surface is provided with a zipper portion that extends in the direction connecting the left and right side edges of the opening and closing surface and divides the opening and closing surface into upper and lower sections, and the adhesive area of ​​the opening and closing surface is surrounded by the zipper portion, the side edges of the opening and closing surface, and the break line formed on the opening and closing surface. The opening and closing surface can be opened without peeling off the adhesive by tearing the zipper portion and then moving (rotating) the opening and closing surface toward the bottom or top surface to which the opening and closing surface is connected.

[0011] In other embodiments, the adhesive area of ​​the opening / closing surface and the area for partially tearing the opening / closing surface are enclosed by the side edge of the opening / closing surface and the break line formed on the opening / closing surface. The opening / closing surface can be opened without peeling the adhesive by first partially tearing the opening / closing surface along the break line, and then moving (rotating) the opening / closing surface toward the bottom or top surface to which it is connected. By partially tearing the opening / closing surface before moving (rotating) it toward the bottom or top surface, the opening / closing surface can be smoothly cut along the break line.

[0012] Preferably, the opening / closing surface is provided with an inner flap that is continuous with the side portion adjacent to the opening / closing surface and is folded at a right angle inward of the opening / closing surface. A break line is formed at the position of the inner flap that overlaps with the area of ​​the opening / closing surface that is to be torn, so as to partially tear the inner flap when the opening / closing surface is partially torn. By providing an inner flap that is continuous with two side portions adjacent to the opening / closing surface on the inside of the opening / closing surface, foreign matter can be effectively prevented from entering through the gaps on both sides of the opening / closing surface. In addition, since the inner flap can be torn when the opening / closing surface is torn, the inner flap does not hinder the tearing of the opening / closing surface.

[0013] This invention also provides a pattern for making a packaging box formed in the shape of a rectangular parallelepiped. The pattern according to this invention is characterized in that one of the four side surfaces of the packaging box made by the pattern serves as an entrance for the contents, and this entrance is closed by an opening / closing surface which is one of the side surfaces that is continuous with the bottom surface or top surface and folded at a right angle, and at least one of the left or right sides of the opening / closing surface is used as the adhesive area for a sealing member to fix the opening / closing surface to the other surface, and the adhesive area of ​​the opening / closing surface is surrounded by the side edge of the opening / closing surface and a break line formed on the opening / closing surface.

[Figure 2] This is a perspective view of the packaging box for Kagami Mochi (rice cake offering) according to the first embodiment. [Figure 3] This is a perspective view showing the opening of the packaging box for the Kagami Mochi (rice cake offering) according to the first embodiment. [Figure 4] This shows a pattern for making a packaging box for Kagami Mochi (rice cake offering) according to the second embodiment. [Figure 5] This is a perspective view showing the opening of the packaging box for the Kagami Mochi (rice cake offering) according to the second embodiment. [Figure 6] This shows a pattern for making a packaging box for Kagami Mochi (rice cake offering) according to the third embodiment. [Figure 7]This shows a pattern for making a packaging box for Kagami Mochi (rice cake offering) according to the fourth embodiment. [Examples]

[0015] Figures 1 to 3 show the first embodiment. Figure 1 is a single template (blank) for making a Kagami Mochi packaging box, and Figure 2 is a perspective view of the Kagami Mochi packaging box assembled using this template. Figure 3 shows the Kagami Mochi packaging box being opened. Figures 2 and 3 show the Kagami Mochi packaging box with the Kagami Mochi set stored inside.

[0016] Figure 1 shows the unfolded diagram of the packaging box, representing the outer surface of a single die-cut cardboard template (blank) 1A. Mountain folds are indicated by dashed lines, and valley folds are indicated by double-dash lines.

[0017] In a single template 1A for forming the packaging box 1B (see Figure 2), the bottom portion 14, front portion 11, top portion 12, rear portion 13, and adhesive margin 13A are arranged in a continuous horizontal row. One side portion 15 (which becomes the right side portion when the packaging box is viewed from the front) (this side portion will be referred to as the "opening / closing surface portion 15" as it will be the opening / closing surface) is formed on the bottom portion 14 in a direction perpendicular to the direction of the horizontal row mentioned above. A locking tab 15A is continuously formed on the tip of the opening / closing surface portion 15. In addition, the front portion 11 and the rear portion 13 have side inner flaps 17A and 17B that extend continuously in the same direction as the opening / closing surface portion 15.

[0018] The other side (which becomes the left side when the packaging box 1B is viewed from the front) is formed by a side portion 16A, an upper side portion 16B, a side portion 16C, and a lower side portion 16D that extend continuously from the front portion 11, top portion 12, rear portion 13, and bottom portion 14 to the side opposite the opening / closing portion 15. When the packaging box is formed, parts of these portions 16A to 16D overlap each other to close the left side of the packaging box 1B. Portions 16A and 16C have arc-shaped edges 18a and 18b that interlock when they overlap. Portions 16B and 16D are approximately trapezoidal.

[0019] A window 20 is formed from the front part 11 to the upper part 12. The window 20 is provided for allowing a mochi cake set or the like stored in the packaging box 1B to be visible from the front and the upper surface (perspective window), and a transparent resin sheet 21 is provided so as to close this window 20. The entire periphery of the transparent sheet 21 is adhered (pasted) to the inner surfaces of the front part 11 and the upper part 12. In this embodiment, the window of the front part 11 is formed in a rectangular shape, and the window of the upper part 12 is formed such that its tip (the part near the rear part 13) is outwardly arcuate. The shape of the window 20 can be arbitrarily designed.

[0020] A zipper part 15a extending in the lateral direction is formed in the opening / closing surface part 15. The zipper part 15a is a range sandwiched by two zipper breaking lines L1 and L2 formed in parallel with each other laterally with a space therebetween. The zipper breaking lines L1 and L2 are formed from one side edge to the other side edge of the opening / closing surface part 15. Thus, the zipper part 15a is also formed from one side edge to the other side edge of the opening / closing surface part 15. The zipper breaking lines L1 and L2 are formed by a plurality of cuts continuously formed discontinuously, and the shape of the cuts may be a short straight line, a small hole, or a small bent shape as shown in the figure, or any shape as long as the zipper part 15a can be easily torn from the opening / closing surface part 15 by picking up and pulling one end of the zipper part 15a. The zipper breaking lines L1 and L2 are also called perforations, cutting dotted lines, etc.

[0021] Continuously with the zipper breaking line L2 closer to the bottom surface part 14 among the two zipper breaking lines L1 and L2 defining the zipper part 15a, a pair of opening breaking lines L3 and L4 extending in a direction perpendicular to the lateral direction in which the zipper breaking lines L1 and L2 extend are formed. The pair of opening breaking lines L3 and L4 are formed with a space therebetween, and both extend in a direction perpendicular to the zipper breaking line L2 (the direction approaching the bottom surface part 14). On the way, the direction is changed, and one opening breaking line L3 extends obliquely to the left and reaches the left edge of the opening / closing surface part 15, and the other opening breaking line L4 changes the direction on the way and extends obliquely to the right and reaches the right edge of the opening / closing surface part 15.

[0022] The range below the zipper part 15a of the opening / closing surface part 15 (the side closer to the bottom surface part 14) is partitioned into a range 15b surrounded by the zipper part 15a (zipper break line L2), the opening break line L3, and the opening break line L4, and a pair of left and right ranges 15c surrounded by the zipper part 15a (zipper break line L2), the side edges of the opening / closing surface part 15, and the opening break lines L3 and L4 respectively. Hereinafter, the range 15b is referred to as the rotating part 15b, and the range 15c is referred to as the adhesion range part 15c.

[0023] When the template 1A shown in FIG. 1 is folded along the fold lines and assembled, a rectangular parallelepiped packaging box 1B as shown in FIG. 2 is formed. The adhesive margin 13A of the rear surface part 13 is pasted on the inner surface of one side part of the bottom surface part 14. The left side surface part is folded so that each of the parts 1,6A to 16D enters the inside, and further, the parts 16A and 16C are folded along the previously formed fold lines. The range of the tip part beyond the fold lines of the parts 16A and 16C overlaps the parts 16D and 16B, and this overlapping part is pasted. By raising the box so as to cancel the folding of the parts 16A and 16C folded along the fold lines, the left side surface part is formed by the parts 16A to 16D. At this time, the arcuate sides 18a and 18b engage with each other. The left side surface part is of a type called an auto bottom, but it is not necessarily required to be of the auto bottom type.

[0024] The right side surface of the packaging box 1B serves as the entrance and exit for the kagami mochi set. After the kagami mochi set 30 is stored in the packaging box 1B, the side inner flaps 17A and 17B are bent at right angles to cover the front and rear ends of the entrance and exit. Finally, the locking tongue piece 15A of the opening / closing surface part 15 is bent at approximately a right angle, the opening / closing surface part 15 is bent at a right angle at the boundary with the bottom surface part 14, and the locking tongue piece 15A is inserted into the packaging box 1B along the inner surface of the upper surface part 12. The assembly of the packaging box 1B is completed.

[0025] The dimensions of the packaging box 1B are formed to match the dimensions of the Kagami Mochi set 30 that will be stored inside the packaging box 1B. When the dimensions of the Kagami Mochi set 30 are large, and consequently the dimensions of the packaging box 1B are also large, gaps tend to form on both sides of the opening / closing surface 15 that closes the entrance of the packaging box 1B. To close the gaps on both sides of the opening / closing surface 15, adhesive tape 40 is applied from both sides of the opening / closing surface 15 to the front surface 11 and the rear surface 13, respectively, so that both sides of the opening / closing surface 15 and the front surface 11 and the rear surface 13 are fixed together. On the opening / closing surface 15, the adhesive tape 40 is applied within the adhesive area 15c. The packaging box 1B containing the Kagami Mochi set 30 is transported or displayed in stores in this state.

[0026] Customers can view the kagami mochi set 30 (for example, a kagami mochi-shaped pack with various decorations placed on three sides) inside the packaging box 1B through a window (see-through window) 20 covered with a transparent sheet 21.

[0027] When removing the Kagami Mochi set 30 from the packaging box 1B, the opening / closing surface 15 of the packaging box 1B is opened. Referring to Figure 3, pinch the left end (or right end) of the zipper portion 15a with your hand and tear the zipper portion 15a sideways along the zipper break lines L1 and L2. The opening / closing surface 15 is separated into an upper area connected to the locking tab 15A and a lower area (rotating portion 15b and adhesive portion 15c) connected to the bottom portion 14.

[0028] When you place your finger on the upper edge of the rotating part 15b and move (rotate) the rotating part 15b downward, the rotating part 15b is cut away from the opening / closing surface part 15 along the opening break lines L3 and L4. By rotating the rotating part 15b until it is flush with the bottom surface part 14, the right side of the packaging box 1B opens wide.

[0029] While the rotating part 15b moves (rotates), the pair of adhesive areas 15c remain overlapped with the inner side flaps 17A and 17B. However, since the adhesive areas 15c are only overlapped with the inner side flaps 17A and 17B by the adhesive tape 40, when the inner side flaps 17A and 17B are opened outward, the adhesive areas 15c move together with the inner side flaps 17A and 17B.

[0030] In this way, the opening / closing surface 15 can be opened without removing the adhesive tape 40 used to close the opening / closing surface 15.

[0031] Instead of using adhesive tape 40, hot melt adhesive may be used to bond the back side (inner surface) of the bonding area 15c to the inner side flaps 17A and 17B.

[0032] The opening / closing surface 15 may be connected to the top surface 12 instead of the bottom surface 14. In this case, the rotating part 15b of the opening / closing surface 15 will move (rotate) upward.

[0033] Figure 4 shows the pattern 2A for making the Kagami Mochi packaging box of the second embodiment. Figure 5 shows the opening of the Kagami Mochi packaging box 2B of the second embodiment. The same reference numerals are used for the same components as the Kagami Mochi packaging box 1B and its pattern 1A of the first embodiment shown in Figures 1 to 3, and redundant explanations are omitted.

[0034] The Kagami Mochi packaging box 2B of the second embodiment has a pair of opening break lines L5 and L6 that define the adhesive area 15c formed on the opening / closing surface 15, similar to the first embodiment, but differs from the Kagami Mochi packaging box 1B of the first embodiment in that it does not have a zipper 15a and the zipper break line that defines it. Referring to Figure 5, when removing the Kagami Mochi set 30 from the packaging box 2B of the second embodiment, the locking tab 15A is removed from the packaging box 2B and the opening / closing surface 15 is moved downward (rotated). The adhesive area 15c is cut from the opening / closing surface 15 along the opening break lines L5 and L6. In the second embodiment as well, if adhesive tape 40 for securely closing the opening / closing surface 15 is applied to the adhesive area 15c surrounded by the opening break lines L5 and L6 and the side edge of the opening / closing surface 15, the opening / closing surface 15 can be opened without peeling off the adhesive tape 40.

[0035] Figure 6 shows a template 3A for making a packaging box for Kagami Mochi according to the third embodiment. The same reference numerals are used for the same components as the packaging box 2B for Kagami Mochi according to the second embodiment shown in Figures 4 and 5, and its template 2A, to avoid redundant explanations.

[0036] The packaging box of the third embodiment differs in that the opening break lines L7 and L8 are formed to occupy a slightly larger area than the opening break lines L5 and L6 of the packaging box 2B of the second embodiment. The upper part of the opening break lines L7 and L8 is formed in an arc shape, and by pressing a finger into the area enclosed by the arc shape (the indentation area) (the area where the star mark is printed in Figure 6), a portion of the opening break lines L7 and L8 can be pre-broken (broken). After breaking the indentation area, the locking tab 15A is removed from the packaging box 2B and the opening / closing surface 15 is moved downward (rotated), which allows for smooth breaking of the opening / closing surface 15 along the opening break lines L7 and L8.

[0037] Figure 7 shows the pattern 4A for making the packaging box for the Kagami Mochi of the fourth embodiment. The same reference numerals are used for the same components as in the pattern 3A for making the packaging box for the Kagami Mochi of the third embodiment shown in Figure 6 to avoid redundant explanations.

[0038] The packaging box for Kagami Mochi in the third embodiment differs from the one for Kagami Mochi in Figure 6 in that roughly semi-circular break lines L9 and L10 are formed on the inner side flaps 17A and 17B, respectively. The semi-circular area enclosed by the break lines L9 and L10 formed on the inner side flaps 17A and 17B is formed in a position that overlaps with the indentation area formed on the opening / closing surface 15 when the packaging box for Kagami Mochi is assembled. When the indentation area of ​​the opening / closing surface 15 is pressed with a finger, the semi-circular area defined by the break lines L9 and L10 on the flaps 17A and 17B is also pressed and punched out. The flaps 17A and 17B can be made so as not to interfere with the pressing (punching) of the indentation area of ​​the opening / closing surface 15. [Explanation of symbols]
