Description

[Technical field]

[0001] This invention relates to a packaging box for packaging items, and in particular to a packaging box suitable for storing individually packaged (small packaged) supplements, medicines, sweets, cooling agents, and the like. [Background technology]

[0002] Several individually packaged products may be stored in a packaging box for sale. In particular, for products that are sensitive to moisture and have a fixed dosage (amount), such as supplements and medicines, if the amount is individually packaged in advance, there is no need to measure each time you take it.

[0003] Patent Document 1 discloses a bottom-lock type packaging box that is assembled by folding a plate-shaped blank. When the cover plate is closed, an insert piece connected to the cover plate is inserted into the box.

[0004] When the lid plate is closed, the insert piece connected to the lid plate is aligned with the inner surface of the blank located at the front of the packaging box. If multiple thin individually packaged products are stored in a packaging box in a line in the direction connecting the front and back of the packaging box, the insert piece may not be aligned with the front of the packaging box when the lid plate is closed, and the individually packaged products may be sandwiched between the front of the packaging box and the insert piece. The individually packaged products sandwiched between the front of the packaging box and the insert piece are not completely contained in the packaging box and protrude and are visible from the outside, which makes it look unattractive. Of course, the packaging box containing the individually packaged products cannot be shipped in such a state, so it is necessary to open the lid plate again, place the individually packaged products completely inside the packaging box, and then close the lid plate again, which is time-consuming. In order to prevent the individually packaged products from being sandwiched, the packaging box must be tilted to move the individually packaged products stored in the box toward the back side of the box body before closing the lid.

[0005] [Patent Document 1] JP 2009-96552 A Summary of the Invention [Problem to be solved by the invention]

[0006] The object of this invention is to prevent individually packaged items from becoming pinched between the front (anterior) of the box body and the insertion piece of the lid when the lid is closed, and to ensure that all of the individually packaged items inside the box are contained within the box simply by closing the lid. [Means for solving the problem]

[0007] The packaging box of this invention is a rectangular cylindrical packaging box having opposing front and back panels, opposing left and right side panels, and opposing lid and bottom panels, and is characterized in that an insert piece that is inserted into the packaging box is connected to the tip of the lid panel, and a fold-back panel that is folded inward (towards the inside of the packaging box) with a rebound in an upward direction is connected to the upper end of the front panel, and the tip edge of the insert piece fits along the fold-back panel when the lid panel is closed.

[0008] According to this invention, since the fold-back panel is connected to the upper end of the front panel and folded inward with a rebound in the rising direction, when the lid panel is closed, the leading edge of the insertion piece at the leading end of the lid panel slides along the fold-back panel, i.e., on the fold-back panel, and is placed inside the packaging box. The individual packaged items inside the packaging box are not pinched between the front panel and the insertion piece. Even if the packaging box is tilted to move the individual packaged items stored inside the box toward the back panel and then the lid is closed, the lid can be closed with all of the individual packaged items securely placed inside the packaging box.

[0009] For example, if the packaging box is made of paper (paperboard), the fold-back panel attached to the upper end of the front panel will rise up due to the repulsion of the paper after it is folded inward. The same is true for synthetic resin sheets. If the material has such a repulsive force, that is, if the material does not overlap with the inner surface of the front panel when folded, the packaging box according to this invention can be constructed.

[0010] In one embodiment, a hole is provided across the boundary between the front panel and the fold-back panel. When the fold-back panel is folded back, a notch is formed in the upper edge of the front panel, through which the hand (fingers) can be placed on the insert.

[0011] Preferably, the packaging box is provided with a partition plate (middle partition) that divides the inside of the packaging box into a plurality of compartments. Individually packaged items can be stored in each of the partitioned spaces (storage chambers) inside the packaging box, and the individual packaged items can be stored in an aligned state inside the packaging box.

[0012] In one embodiment, the partition plate includes a horizontal partition piece extending in a direction connecting the left and right side panels of the packaging box, and a vertical partition piece extending in a direction connecting the front and back panels of the packaging box, and the vertical partition piece is formed with a step portion that engages with the tip of the folded panel that is about to rise and prevents the folded panel from rising midway. The folded panel is prevented from coming out of the packaging box due to its rebound.

[0013] Preferably, a stopper is formed on each of the front and back sides of the partition plate to prevent the individual packages stored in each compartment of the packaging box from being pinched between the partition plate and the front and back panels of the packaging box, thereby preventing the individual packages from being pinched in the gap between the partition plate and the packaging box, making it difficult to remove the individual packages.

[0014] Packaging boxes are made by cutting, folding and gluing a single sheet of cardboard, a synthetic resin sheet or a combination of these materials. The same goes for dividers, but they do not necessarily need to be glued. [Brief description of the drawings]

[0016] Figures 1 and 2 show the packaging box body. Figure 1 shows the template (blank) (developed view) that forms the packaging box body 1, and shows the surface that will become the exterior of the packaging box body 1. The template is made by cutting out cardboard, cardboard, plastic sheets, and composite materials into the shape shown in Figure 1. The dashed and dotted lines indicate the fold lines that will be mountain folds when assembling the packaging box body 1, and the dashed and two-dotted lines indicate the fold lines that will be valley folds when assembling the packaging box body 1. To make folding easier, fold lines or creases are applied along the dashed and two-dotted lines.

[0017] Referring to Figure 1, the packaging box body 1 has a glue tab 11, a back panel 12, a left side panel 13, a front panel 14, and a right side panel 15, which are connected horizontally from left to right via a fold line.

[0018] A cover panel 31, a flap 32, a fold-back panel 33, and a flap 34 are connected to the upper ends of the rear panel 12, the left side panel 13, the front panel 14, and the right side panel 15. An insertion piece 35 is further connected to the tip of the cover panel 31.

[0019] The rear panel 12, the left side panel 13, the front panel 14, and the right side panel 15 are connected to the lower ends of the rear side bottom piece 21, the left side bottom piece 22, the front side bottom piece 23, and the right side bottom piece 24, which form the bottom surface of the packaging box main body 1. When the packaging box main body 1 is assembled, a portion of these bottom pieces 21 to 24 overlap each other. The rear side bottom piece 21 and the front side bottom piece 23 are formed with interlocking notches 21a, 23a that interlock (engage) when overlapped. In addition, diagonal fold lines are formed from the corners toward the interlocking notches 21a, 23a near the left side bottom piece 22 of the rear side bottom piece 21 and near the right side bottom piece 24 of the front side bottom piece 23, and the fold lines define approximately triangular fixed adhesive pieces 21b, 23b, respectively.

[0020] Circular holes 17, 37 are formed in the front panel 14 and the folded panel 33 connected to the upper end of the front panel 14. The circular holes are located approximately in the center of the front panel 14 and the folded panel 33 in the left-right direction, with the upper semicircular hole 37 formed in the folded panel 33 and the lower semicircular hole 17 formed in the front panel 14. In other words, the circular holes 17, 37 are formed across the fold line at the boundary between the front panel 14 and the folded panel 33. When the folded panel 33 is folded completely (180 degrees), the semicircular hole 17 in the front panel 14 and the semicircular hole 37 in the folded panel 33 overlap, forming a semicircular cutout (see FIG. 2). The insertion piece 35 is exposed through the cutout, making it easier to open the closed cover panel 31 by hooking a finger on the insertion piece 35.

[0021] It is not essential to form the notches (semicircular holes 17, 37 described above) in the front panel 14. For example, if a pair of short notches extending toward the insertion piece 35 and a notch connecting the tips of the pair of notches are formed at the boundary between the lid panel 31 and the insertion piece 35, a short protrusion extending outward from the boundary between the lid panel 31 and the insertion piece 35 is formed when the insertion piece 35 is folded, and the lid panel 31 can be easily opened by hooking a finger on this protrusion.

[0022] The packaging box body 1 is assembled as follows: The rear bottom piece 21, the left side bottom piece 22, the front bottom piece 23, and the right side bottom piece 24 are mountain-folded, and the spaces between the rear panel 12 and the left side panel 13, and the spaces between the front panel 14 and the side panel 15 are folded.

[0023] The fixed adhesive piece 21b of the rear bottom piece 21 is valley-folded along the diagonal fold line, and the fixed adhesive piece 23b of the front bottom piece 23 is valley-folded along the diagonal fold line. The backside of the fixed adhesive piece 21b defined on the rear bottom piece 21 is adhered to the front side of the left side bottom piece 22, the backside of the fixed adhesive piece 23b defined on the front bottom piece 23 is adhered to the front side of the right side bottom piece 24, and the glue piece 11 is adhered to the backside of the side panel 15. A blank is formed in a flat folded state.

[0024] When the flattened blank is raised into a rectangular tube shape, the interlocking notch 23a of the front bottom piece 23 and the interlocking notch 21a of the rear bottom piece 21 interlock with each other, and the bottom of the packaging box body 1 is fixed in place.

[0025] Next, the fold-back panel 33 connected to the upper edge of the front panel 14 is folded back in a mountain fold, and then the left and right flaps 32, 34, the lid panel 31, and the insertion piece 35 are also mountain-folded. The insertion piece 35 is inserted into the back surface of the front panel 14 along the top of the fold-back panel 33, that is, while the leading edge of the insertion piece 35 slides over the fold-back panel 33. The packaging box body 1 (Fig. 2) is completed with the opening closed by the lid panel 31.

[0026] Figures 3 and 4 show a partition plate (middle partition) that is inserted into the packaging box body 1. Figure 3 is a template (blank) (developed view) that forms the partition plate 2, showing the surface that will become the outside of the partition plate 2. The template for the partition plate 2 is also made by cutting out cardboard, cardboard, plastic sheet, or a composite material of these into the shape shown in Figure 3. The dashed and dotted lines indicate the fold lines that will be mountain folds when assembling the partition plate 2, and the dashed and two-dotted lines indicate the fold lines that will be valley folds when assembling the partition plate 2. To make folding easier, fold lines or creases are applied along the dashed and two-dotted lines.

[0027] Referring to Figure 3, the partition plate 2 comprises a rear bottom piece 41, two horizontal partition pieces 42, 43, and a front bottom piece 44, which are connected vertically from top to bottom via fold lines, a rear piece 51 connected to the upper edge of the rear bottom piece 41 via a fold line, a pair of vertical partition pieces 52 connected respectively to the left and right ends of the rear piece 51 via fold lines, and a pair of front pieces 53 further connected to the left and right ends of the pair of vertical partition pieces 52.

[0028] Two vertically long slits 46 are formed at a distance in the horizontal partition pieces 42, 43 so as to straddle the boundary between the horizontal partition pieces 42, 43. As described below, when the back faces of the horizontal partition pieces 42, 43 are overlapped and folded at the boundary, a pair of slits 46 is formed that extend vertically at a distance on the left and right and connect to the outside at the upper end (top). The slits 46 have a length of about half the height of the horizontal partition pieces 42, 43.

[0029] At the boundary between the back piece 51 and the vertical partition pieces 52 on the left and right sides, an outward semicircular arc-shaped cut is formed to form a semicircular stopper 51a. At the boundary between the vertical partition piece 52 and the front piece 53, a square cut is formed inward to form a square stopper 53a at the lower part. Furthermore, each of the two vertical partition pieces 52 has a vertical slit 55 that connects to the outside at the lower end. The slit 55 has a height of about half the vertical partition piece 52. The vertical partition piece 52 is lowered in the middle on the front piece 53 side, and the front piece 53 has the same height as the lowered vertical partition piece 52. A step 52a is formed at the point where the height of the vertical partition piece 52 changes.

[0030] The partition plate 2 is assembled as follows. First, the back surfaces of the two adjacent horizontal partition pieces 42, 43 are overlapped along the fold line at the boundary between the two horizontal partition pieces 42, 43, and the back side bottom piece 41 connected to one horizontal partition piece 42 is valley folded outward at a substantially right angle, and the front side bottom piece 44 connected to the other horizontal partition piece 43 is valley folded outward at a substantially right angle. The bottom pieces 41, 44 extend in opposite directions (towards the front and back), forming a shape in which the horizontal partition pieces 42, 43 rise up almost vertically from the boundary between the two bottom pieces 41, 44.

[0031] The vertical partition pieces 52 connected to the left and right sides of the back piece 51 are folded inward at approximately right angles, and the back piece 51 is further folded inward at approximately right angles. When the vertical partition pieces 52 are folded inward at approximately right angles, the semicircular stoppers 51a protrude outward on the left and right sides of the back piece 51.

[0032] When the back piece 51 is folded in a mountain fold, the slits 55 formed in each of the pair of vertical partition pieces 52 are inserted into the slits 46 of the horizontal partition pieces 42, 43. The pair of vertical partition pieces 52 and the horizontal partition pieces 42, 43 are constrained to each other, creating a shape in which they extend perpendicular to each other.

[0033] Finally, the pair of front pieces 53 are folded outward at a substantially right angle, completing the partition plate 2 (FIG. 4). By folding the front pieces 53, square stoppers 53a protrude inward.

[0034] Fig. 5 shows a state in which the partition plate 2 has been incorporated into the packaging box main body 1. Fig. 6 further shows a state in which individual packages are stored within the packaging box main body 1.

[0035] The depth of the partition plate 2 (the distance from the front piece 53 to the back piece 51) is approximately equal to (or may be slightly shorter than) the depth of the packaging box main body 1 (the distance from the front panel 14 to the back panel 12), and the width of the partition plate 2 (the distance between the left and right ends of the bottom pieces 41, 44) is approximately equal to (or may be slightly shorter than) the width of the packaging box main body 1 (the distance from the left side panel 13 to the right side panel 15). On the other hand, the height of the partition plate 2 (the height of the horizontal partition pieces 42, 43, the height of the vertical partition piece 52, and the height of the back piece 51) is slightly lower than the height of the packaging box main body 1 (the height of the front panel 14, the back panel 12, and the left and right side panels 13, 15). The partition plate 2 is completely contained within the packaging box main body 1. The interior of the packaging box main body 1 is divided into six by the partition plate 2, and six storage chambers are created. Each of the six storage chambers stores a plurality of individual packaged bodies 60 arranged in a direction connecting the front and back of the packaging box main body 1. The individual package 60 is, for example, a thin package of a four-sided sealed type in which each of the four sides is sealed.

[0036] Since the semicircular stoppers 51a protrude outward from the left and right sides of the back piece 51, the individual packaged objects 60 stored in the left and right storage chambers (the left and right storage chambers on the back side) of the storage chamber facing the back piece 51 do not reach the back side of the back piece 51 (are not sandwiched between the back piece 51 and the back panel 12 of the packaging box main body 1). Also, since the square stoppers 53a protrude inward from each of the pair of front pieces 53, the individual packaged objects stored in the storage chamber in the center of the front side do not reach the front of the front piece 53 (are not sandwiched between the front piece 53 and the front panel 14 of the packaging box main body 1).

[0037] The folded panel 33 of the packaging box body 1 tries to rise due to the repulsion, but as it rises, its leading edge gets caught on the step a52 of the vertical partition piece 52, and it cannot rise completely (Figure 5). The folded panel 33 always maintains a state where it is folded at an acute angle relative to the front panel 14.

[0038] When the opening of the packaging box body 1 is closed by the lid panel 31, the insert piece 35 at the tip of the lid panel 31 slides over the folded panel 33 and is stored inside the packaging box body 1. The individual package is not pinched between the insert piece 35 and the front panel 14. [Explanation of symbols]
