Embodiments for Carrying out the Invention

[0016] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. <Configuration of the Tray> FIG. 1 is a perspective view from the opening side of a tray 20 according to an embodiment of the present disclosure. As shown in FIG. 1, the tray 20 has a rectangular bottom plate 21 (see FIG. 2) and four side plates erected from the four sides of the bottom plate 21, and an opening 20a is formed on the upper surface. The side plates can be classified into short side plates 22a, 22b connected to the short sides of the bottom plate 21 and long side plates 23a, 23b connected to the long sides of the bottom plate 21.

[0017] An engaging portion SA is provided at the upper part of the short side plate 22a. Also, an engaging portion SB is provided at the upper part of the short side plate 22b. The engaging portion SA and the engaging portion SB engage with each other when forming the box body 50. When the engaging portion SA and the engaging portion SB engage, the short side plates 22a and 22b form the bottom surface 51 of the box body 50.

[0018] FIG. 2 is a development view of the tray 20. The blank plate 29 obtained by developing the tray 20 is formed by punching out a sheet of paperboard such as manila board, paperboard, cardboard, kraft board, etc. having a predetermined basis weight. Note that the blank plate 29 may be formed of a resin plate.

[0019] The blank plate 29 has a rectangular bottom plate 21. Rectangular short side plates 22a and 22b are attached to the two short sides of the bottom plate 21 via fold lines 26. Rectangular long side plates 23a and 23b are attached to the two long sides of the bottom plate 21 via fold lines 26. In Figure 2, the fold lines 26 are shown as dashed lines. In addition, adhesive tabs 25 are attached to both sides of the opposing long side plates 23a and 23b via fold lines 26. The adhesive tabs 25 may also be attached to both sides of the short side plates 22a and 22b via fold lines 26 instead of the long side plates 23a and 23b. In this embodiment, the rectangular bottom plate 21 has a longitudinal direction (left-right direction in Figure 2) and a short direction (up-down direction in Figure 2). Therefore, the bottom plate 21 is connected to the long side plates 23a and 23b on the side that is longer than the short side plates 22a and 22b.

[0020] The tray 20 has three types of planned fold lines: a first planned fold line, a second planned fold line, and a third planned fold line. The planned fold lines can be of any structure as long as they allow the bottom plate 21 and the long side plates 23a and 23b to be folded. In this embodiment, the first planned fold line F1, the second planned fold line F2, and the third planned fold line F3 are all pressed lines. The bottom plate 21 has two first planned fold lines F1 that extend in the short direction of the bottom plate 21. In this embodiment, the first planned fold line F1 and the second planned fold line F2 are formed continuously from the upper end of the long side plate 23a (upper end in Figure 2) to the upper end of the long side plate 23b (lower end in Figure 2) in the assembled state. The first planned fold line F1 and the second planned fold line F2 do not necessarily need to reach the upper ends of the long side plates 23a and 23b. The goal is to fold the base plate 21 and the long side plates 23a and 23b by folding along the first planned fold line F1.

[0021] The formation position of the first planned fold line F1 is not necessarily limited, but it is preferable that the first planned fold line F1 be symmetrical to the approximate center of the longitudinal direction of the bottom plate 21. By having the two first planned fold lines F1 symmetrically positioned to the center of the longitudinal direction of the bottom plate 21, the height of the top surface 52 of the box body 50 (see Figures 6 and 9) becomes horizontal when the box body 50 is assembled.

[0022] The base plate 21 has two first fold lines F1 that extend along the shorter direction (up and down direction in the drawing) of the base plate 21. Hereafter, when the two first fold lines are not distinguished, they will be referred to as the first fold line F1, and when the two first fold lines are distinguished, they will be referred to as the first fold line F1a and the first fold line F1b, respectively. In this embodiment, the first fold line F1a and the first fold line F1b are parallel to each other. Also, in this embodiment, the first fold line F1 is parallel to the shorter side of the base plate 21 and perpendicular to the longer side of the base plate 21.

[0023] On the long side panels 23a and 23b, a second fold line F2 is formed, extending in the direction of vertical installation of the long side panels 23a and 23b from a position that intersects with the direction in which the first fold line F1 extends. In the unfolded state shown in Figure 2, the first fold line F1 and the second fold line F2 are located on the same straight line. The first fold line F1 and the second fold line F2 are formed continuously from the upper end of the long side panel 23a (upper end in Figure 2) to the upper end of the long side panel 23b (lower end in Figure 2) in the assembled state. The second fold line F2 does not necessarily have to reach the upper ends of the long side panels 23a and 23b. It is sufficient that the bottom panel 21 and the long side panels 23a and 23b can be folded by folding from the first fold line F1.

[0024] In the unfolded state, the second planned fold line F2a, the first planned fold line F1a, and the second planned fold line F2a on the long side panel 23a, the bottom panel 21, and the long side panel 23b are located on a single straight line. Also, the second planned fold line F2b, the first planned fold line F1b, and the second planned fold line F2b on the long side panel 23a, the bottom panel 21, and the long side panel 23b are located on a single straight line.

[0025] On the long side panels 23a and 23b, a third fold line F3 is formed, extending in a direction inclined toward the short side panels 22a and 22b with respect to each second fold line F2, from a position where it intersects with the direction in which each first fold line F1 extends. More specifically, on the long side panels 23a and 23b, a third fold line F3a is formed, extending in a direction inclined toward the short side panel 22a with respect to each second fold line F2a, from point Pa, which is the position where it intersects with the direction in which the first fold line F1a extends. Furthermore, on the long side panels 23a and 23b, a third fold line F3b is formed, extending in a direction inclined toward the short side panel 22b with respect to each second fold line F2b, from point Pb, which is the position where it intersects with the direction in which the first fold line F1b extends.

[0026] In the long side panels 23a and 23b, there are no particular limitations on the angle R formed by the second planned fold line F2 and the third planned fold line F3, but it is preferably 30 degrees or more and 60 degrees or less, and particularly preferably 40 degrees or more and 50 degrees or less. If the angle R formed by the second planned fold line F2 and the third planned fold line F3 is too small, it becomes difficult to overlap the central part of the long side panels 23a and 23b with the bottom panel 21, making it difficult to form a desirable box. If the angle R formed by the second planned fold line F2 and the third planned fold line F3 is too large, the gap portion on the side of the box becomes large, making it difficult to form a desirable box. In this embodiment, the angle R formed by the second planned fold line F2 and the third planned fold line F3 is 45 degrees. Therefore, the angle formed by the second planned fold line F2a and the third planned fold line F3a, and the angle formed by the second planned fold line F2b and the third planned fold line F3b, are both 45 degrees.

[0027] The bottom plate 21 has an opening-forming portion 35 enclosed by a folding line G and a cutting line K1 between two first planned folding lines F1a and F1b. In this embodiment, two opening-forming portions 35 are formed. The number of opening-forming portions 35 may be one or three or more. Considering the balance, two opening-forming portions 35 are optimal. In this embodiment, the opening-forming portion 35 is a rectangular shape that is long in the longitudinal direction of the central portion 21a of the bottom plate. Therefore, the short side of the opening-forming portion 35 is parallel to the folding line 26 that separates the bottom plate 21 from the long side plates 23a and 23b. Also, the long side of the opening-forming portion 35 is parallel to the first planned folding lines F1a and F1b.

[0028] The two short sides of the opening-forming portion 35 are formed by the planned folding lines G. The two long sides of the opening-forming portion 35 are formed by the planned cutting lines K1. Furthermore, the opening-forming portion 35 has a second planned cutting line K2 that is parallel to the two planned folding lines G (the two short sides) and perpendicular to the two planned cutting lines K1 (the two long sides). It is preferable that the second planned cutting line K2 is formed at a position equidistant from the two planned folding lines G.

[0029] After the box body 50 is formed, the area near the center of the opening forming section 35 is pressed, breaking the second planned cutting line K2, and then breaking the planned cutting line K1. This separates the opening forming section 35 into two parts. The separated opening forming section 35 is then bent along the planned folding line G by the pressing force and moves downward. As a result, an opening 36 is formed in the center of the bottom plate 21a.

[0030] In this embodiment, the opening-forming portion 35 is surrounded by the planned bending line G and the planned cutting line K1, but the entire perimeter of the opening-forming portion may be surrounded by the planned cutting line. That is, the opening-forming portion may be surrounded by the planned cutting line. In this case, there may be no second planned cutting line inside the opening-forming portion.

[0031] Figure 3 shows details of the engaging portion SA shown in Figure 2. As shown in Figure 3, the engaging portion SA has a notch 31, a first notch 32a, and a second notch 32b. The notch 31 is a notch formed from the end E of the short side plate 22a toward the bottom plate 21. The first notch 32a is a notch that extends inclined with respect to the direction from the notch 31 toward the bottom plate 21. The second notch 32b is a notch that extends from the end of the first notch 32a toward the long side plate 23a toward the long side plate 23a. In this embodiment, the second notch 32b is parallel to the short side and end E of the bottom plate 21. The engaging portion SB has the same form as the engaging portion SA.

[0032] The engaging portion SA formed on the short side plate 22a and the engaging portion SB formed on the short side plate 22b are identical in shape. Furthermore, the engaging portions SA and SB are formed at positions that are point-symmetric with respect to the center of the bottom plate 21. As a result, the portions enclosed by the notch 31, the first cutout 32a, and the second cutout 32b engage with each other, allowing the short side plates 22a and 22b to be fixed together.

[0033] The tray 20 is formed by folding the blank plate 29 along the fold lines 26. Specifically, the four side plates are folded from the periphery of the bottom plate 21 and erected, and the adhesive tabs 25 are attached to the inner surfaces of adjacent short side plates using adhesive. This forms a tray 20 as shown in Figure 1, in which adjacent side plates are connected to each other.

[0034] Alternatively, instead of the adhesive tab 25, insertion pieces that are inserted into slits formed in the adjacent short side panels 22a and 22b can be provided on both sides of the long side panels 23a and 23b to connect the adjacent side panels. Note that the adhesive tab 25 is omitted from the illustration in Figure 1.

[0035] Figure 4 is a perspective view showing the deformation of the tray 20. In Figure 4, as in Figure 1, the bottom plate 21 is facing downwards and the opening 20a is facing upwards. From the state shown in Figure 1, the long side plates 23a and 23b are each further folded from the fold line 26 so that their central portions overlap the bottom plate 21. At the same time, the second planned fold line F2 is folded so that it protrudes toward the bottom plate 21, and the third planned fold line F3 is folded so that it protrudes toward the outside of the tray. Figure 4 shows the state at this point. In the state shown in Figure 4, the central part 21a of the bottom plate, sandwiched between the first planned fold line F1a and the first planned fold line F1b, is in contact with the mounting surface, while the side parts 21b and 21c of the bottom plate are each floating away from the mounting surface.

[0036] From the state shown in Figure 4, the fold line 26 is further folded so that the long side panels 23a and 23b come into contact with the center portion 21a of the bottom panel. At this point, the second planned fold line F2 completely overlaps the first planned fold line F1. Next, the overlapping first planned fold line F1 and the second planned fold line F2 are folded with the center portion 21a of the bottom panel facing outwards. This brings the short side panels 22a and 22b closer together. Then, the engaging portion SA and the engaging portion SB are engaged from the state where the short side panels 22a and 22b are in contact. In this way, the box body 50 is formed.

[0037] As a result, the connected short side panels 22a and 22b form a new bottom surface 51, and the side facing this bottom surface 51 becomes the top surface 52, forming a box body 50. Figure 5 is a perspective view of the box body 50 from the bottom surface 51 side. As shown in Figure 5, the short side panels 22a and 22b engage with each other at the engaging portion SA and engaging portion SB to form a new bottom surface 51. The bottom panel side portion 21b becomes the side surface 53 of the box body 50, and the bottom panel side portion 21c becomes the side surface 54 of the box body 50. Side surfaces 53 and 54 face each other. The long side panels 23a and 23b are each partially bent, and the parts excluding the central portion form the sides 55 and 56 of the box body 50. Side surfaces 55 and 56 face each other.

[0038] Subsequently, on the upper surface 52, the opening 36 is formed by cutting along the planned cutting line around the opening forming portion 35 and folding inward along the planned folding line around the opening forming portion. In this embodiment, two opening forming portions 35 are formed on the upper surface 52. Therefore, two openings 36 are formed. In this way, a box body 50 having openings 36 on the upper surface 52 is assembled. Figure 6 is a perspective view showing the assembled box 50. In Figure 6, the orientation is reversed compared to Figure 5, showing the box 50 viewed from the top surface 52. As shown in Figure 6, two openings 36 are formed on the top surface 52 of the box 50. It is also envisioned that the assembly of such a box 50 may be performed by the consumer who purchased the product.

[0039] Next, the state in which the contents are contained will be described. Figure 7 is a perspective view showing the contents contained in the tray. As with Figure 1, Figure 7 is viewed from the side of the opening 20a. In the example of Figure 7, eight contents N, which have a substantially cylindrical outer shape, are contained. When assembling and using the box body 50 from the tray 20 according to this embodiment, it is preferable to arrange and contain the contents N so that the longitudinal direction of the contents N is aligned with the short direction of the bottom plate 21. Here, the direction is preferably parallel. However, since it is difficult to arrange them strictly parallel within the tray 20, it is sufficient if the directions are aligned to the extent that the contents N can be contained substantially aligned within the tray 20.

[0040] <Features of the packaging bag> The packaging 100 is constructed by housing a tray 20 inside a packaging bag 10. Figure 8 is a perspective view showing the packaging 100 constructed by sealing the tray 20 inside the packaging bag 10. The packaging bag 10 is visible from the outside, and if it is transparent, the tray 20 inside is also visible. In the example in Figure 8, the tray 20 is not shown. When the tray 20 is housed inside, the packaging bag 10 has a top surface 12, a bottom surface 13, and a pair of side surfaces 14. The top surface 12 faces the opening 20a of the tray 20, and the bottom surface 13 faces the bottom plate 21 of the tray 20. The side surfaces 14 connect the top surface 12 and the bottom surface 13. The packaging 100 shown in Figure 8 is a packaging in which the contents N are housed in the tray 20 such that the longitudinal direction of the contents is aligned with the short direction of the tray 20.

[0041] The packaging bag 10 is formed into a cylindrical body by joining the opposing edges of the laminated film with a gusset seal portion, which is located on the bottom surface 13. The opening of the cylindrical body is heat-sealed with a heat-seal portion to seal the tray 20.

[0042] The heat-bonded portion is formed by folding the side portion 14 inward, sandwiching it between the top portion 12 and the bottom portion 13, and then heat-bonding it by sandwiching it from the outside with a sealing bar.

[0043] Furthermore, sealing portions are formed along the edges connecting the side portion 14 and the top portion 12, and along the edges connecting the side portion 14 and the bottom portion 13. By forming these sealing portions, the packaging bag 10 can be formed to conform to the shape of the tray 20, and the size of the packaging body 100 can be reduced.

[0044] Each sealed portion is formed by folding the innermost heat-adhesive resin layers of the laminated film over by a predetermined width so that they face each other, and then sandwiching them from the outside with a sealing bar and heat-bonding them. Preferably, the sealed portion is formed with a seal width of 5 mm to 15 mm.

[0045] The user grasps the gusseted seal portion with one hand and the top portion 12 with the other hand, and pulls both hands apart, thereby separating the seal portion between the top portion 12 and the bottom portion 13 and forming an opening. The tray 20 is then pulled out of the packaging bag 10 through the opening.

[0046] The laminated film constituting the packaging bag 10 consists of a base layer and a heat-adhesive resin layer, which are laminated in that order. An intermediate layer consisting of a metal foil or a metal vapor-deposited film having gas barrier properties may be placed between the base layer and the heat-adhesive resin layer.

[0047] The base layer can be made of a resin film, and any known resin such as nylon, polyethylene terephthalate, or polyethylene naphthalate can be arbitrarily selected. Alternatively, one or more of these resins may be used to form the base layer. In addition, a paper base material may be used instead of a resin film.

[0048] A printing layer is placed on the outer surface of the base material layer, and the printing layer is formed by printing and applying ink material to predetermined positions using gravure printing or offset printing. The printing layer allows for the arbitrary formation of desired patterns, such as letters, figures, or symbols, on the outer surface of the base material layer.

[0049] The heat-adhesive resin layer is composed of a resin that melts with heat and fuses to the opposing heat-adhesive resin layer for heat bonding. Examples of polyolefin resins include low-density polyethylene, medium-density polyethylene, high-density polyethylene, ethylene-α-olefin copolymer, polypropylene, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-propylene copolymer, and methylpentene polymer.

[0050] Next, the method of using the tray 20 will be explained. Figure 8 is a perspective view showing a package 100 formed by sealing the tray 20 in a packaging bag 10. As shown in Figure 7, the tray 20 containing the product N is inserted into the packaging bag, and the outside of the packaging bag is sealed to obtain a package 100 containing the product N. It is also conceivable that the product will be distributed in this state, with the contents N contained in the package 100. In the package 100 as shown in Figure 8, the consumer opens the packaging bag 10 and takes out the tray 20 as shown in Figure 7. That is, the consumer takes out the contents N from the tray 20, which are arranged so that their longitudinal direction is aligned with the short direction of the bottom plate 21 of the tray 20.

[0051] Then, with the contents removed from the tray 20 as shown in Figure 1, the tray 20 is folded along the second planned fold line F2 and the third planned fold line F3. From the state shown in Figure 4, the long side panels 23a and 23b are further folded towards the bottom panel 21. Furthermore, with the first planned fold line F1 and the second planned fold line F2 overlapping, the first planned fold line F1 and the second planned fold line F2 are folded so that the short side panels 22a and 22b are brought closer to each other. Subsequently, the engaging portion SA of one short side panel 22a and the engaging portion SB of the other short side panel 22b are engaged to form a single bottom surface 51 with the short side panels 22a and 22b. In this way, the box body 50 is formed.

[0052] Once the box 50 is completed, the contents N that were previously stored inside can be re-stored inside. Figure 9 shows the box 50 with the contents re-stored inside. As shown in Figure 9, the contents N are re-stored inside the box 50 with the bottom surface 51 of the formed box 50 facing downwards. Specifically, the contents N are stored upright so that their longitudinal direction is from the opening 36 towards the bottom surface 51. In the example in Figure 9, four contents N are stored inside each opening 36. The height of the box 50 (distance between the bottom surface 51 and the top surface 52) is the length of the sides 21b and 21c of the bottom plate 21 of the tray 20 in the longitudinal direction. The storage configuration of the goods during distribution can be arbitrarily determined according to the size of the goods and the size of the tray. For example, an efficient storage configuration is when the length of the goods in the longitudinal direction fits within the short-length direction of the bottom plate 21 of the tray 20. For example, the lengths of the sides 21b and 21c of the bottom plate 21 of the tray 20 in the longitudinal direction are made longer than half the length of the bottom plate 21 in the short direction. As a result, the height of the box 50 will exceed half the length of the product in the longitudinal direction. Therefore, as shown in Figure 9, when the product is stored vertically, the portion of the product exceeding half will be contained within the box 50. This allows the contents N, which are the product, to be held stably.

[0053] Furthermore, the side portion 14 of the packaging bag 10 has a heat-sealed portion formed along the edge that connects to the top portion 12 and the bottom portion 13. This allows the packaging bag 10 to be formed to conform to the shape of the tray 20. As a result, the package body 100 containing the tray 20 can be made smaller.

[0054] While preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments and various modifications are possible. For example, in the above embodiments, a substantially cylindrical shape was used as the contents, but the shape of the contents is not particularly limited. However, it is preferable that the contents have a longitudinal direction, and that the length of the contents in the longitudinal direction is shorter than the length of the bottom plate of the tray. With this relationship, when the goods are distributed, the contents can be arranged in the longitudinal direction of the bottom plate of the tray. As long as the contents have a longitudinal direction, they can be prismatic, conical, pyramidal, or similar shapes.
