Description

Technical Field

[0005]

[0001] The present invention relates to a packaging box, and more particularly to a packaging box having an inner box portion and an outer box portion.

Background Art

[0002] Conventionally, as a packaging box having an inner box portion having a bottom surface portion and an inner sleeve-like portion, and an outer box portion covering the inner box portion, and having an outer sleeve-like portion provided with outer side surface portions corresponding to the respective inner side surface portions constituting the inner sleeve-like portion, there are the packaging boxes described in Patent Document 1 and the packaging boxes described in Patent Document 2.

[0003] Here, the packaging box A described in Patent Document 1 has an inner box portion A1 and an outer box portion A2. The inner box portion A1 has a bottom surface portion 50 and a sleeve-like portion 5. In the side surface portions 20 and 30 of the sleeve-like portion 5, a part thereof is formed as a separation portion 24 and 34 so as to be separable from other portions via perforations K2, K6, etc. The outer box portion A2 has a sleeve-like portion 105 and upper surface portions 160 to 190. In the side surface portion 120 of the sleeve-like portion 105, a piece portion 126 is provided by a cut 122, and in the side surface portion 130, a piece portion 136 is provided by a cut 132. The separation portion 24 and the piece portion 126 are adhered, and the separation portion 34 and the piece portion 136 are adhered.

[0004] When using the packaging box A of Patent Document 1, with the product stored in the packaging box A, the upper surface portions 160 to 190 are in a closed state. When taking out the stored product, by rotating the piece portions 126 and 136 outward, the perforations K2 and K6 are broken, and the separation portions 24 and 34 are separated from the inner box portion A1. Thus, by pulling up the outer box portion A2 upward, the inner box portion A1 in the state of storing the product remains, and the product can be taken out from the inner box portion A1.

[0005] Furthermore, the packaging box A described in Patent Document 2, like the packaging box A in Patent Document 1, has an inner box portion A1 and an outer box portion A2. In particular, the inner box portion A1 has a front portion 10 which includes a lower component portion 12, an upper component portion 14, and a shelf portion 16. By inserting the protruding portion 16b-2 of the contact piece portion 16b of the shelf portion 16 into the opening 42a of the back portion 40, the shelf portion body portion 16a is positioned laterally, so that products can be stored in the lower and upper sections via the shelf portion body portion 16a.

[0006] In the packaging box A of Patent Document 2, after rotating the piece 122 to separate the separation piece 24 from the inner box A1, the piece 122 is pulled towards the front 110 to break the perforations 129a and 129b, then the perforation 112 on the front side is broken, and then the perforation 132 on the left side is broken, thereby separating the separation piece 34 from the inner box A1. By pulling the outer box A2 upward, the inner box A1 with the products stored in the lower and upper sections remains. Products stored in the upper section can be removed from above, and products stored in the lower section can be removed from the side. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Utility Model Registration No. 3139948 Gazette [Patent Document 2] Utility Model Registration No. 3147083 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0008] However, in the packaging boxes described in Patent Documents 1 and 2, in order to remove the product stored in the inner box, it is necessary to pull up and remove the outer box, which is a troublesome process, and also has the problem that the removed outer box must be discarded.

[0009] Therefore, the present invention aims to provide a packaging box in which the product stored in the inner box can be removed without removing the outer box, in a packaging box having an inner box portion having a bottom portion and an inner sleeve-shaped portion, and an outer box portion covering the inner box portion, with an outer sleeve-shaped portion having an outer side portion corresponding to each inner side portion that constitutes the inner sleeve-shaped portion. [Means for solving the problem]

[0010] This invention was created to solve the above problems, and firstly, it is a packaging box having an inner box portion (A) and an outer box portion (B), the inner box portion and the outer box portion each being formed from a sheet-like blank, the inner box portion having a bottom portion (50) and an inner sleeve-shaped portion (1) that is erected from each side of the bottom portion and perpendicular to the bottom portion, the inner sleeve-shaped portion having an inner front portion (10), an inner right side portion (20), an inner left side portion (30), and an inner back portion (40), and the outer box portion having an outer sleeve-shaped portion (10) provided along the outer surface of the inner box portion 1) An outer sleeve-shaped portion having an outer front portion (110) formed along the outer surface of the inner front portion, an outer right side portion (120) formed along the outer surface of the inner right side portion, an outer left side portion (130) formed along the outer surface of the inner left side portion, and an outer rear portion (140) formed along the outer surface of the inner rear portion, and a lid portion (160) connected to the upper end of the outer sleeve-shaped portion via a folded line, wherein at least one of the four surfaces of the outer sleeve-shaped portion, the outer front portion, the outer right side portion, the outer left side portion, and the outer rear portion The outer specific surface portion (110, 140), which is the surface portion, has an outer main body portion (111) connected to an adjacent surface portion of the outer sleeve-shaped portion, and a rotating piece portion (112) provided in the inner region of the outer main body portion and connected to the outer main body portion via a first fold line (C30) and a first cut line (K10) formed from both ends of the first fold line, and the inner specific surface portions (10, 40), which are surface portions along the inner surfaces of the outer specific surface portion of the four surface portions of the inner sleeve-shaped portion, the inner front portion, the inner right side portion, the inner left side portion, and the inner back portion, are located in the inner sleeve-shaped portion The outer body has an inner body portion (11) connected to adjacent surface portions and bottom portions, and an outlet forming portion (12) having an outlet body portion (13) connected to the inner body portion via a second fold line (C20) parallel to the first fold line and bonded to a rotating piece portion, and an outlet forming portion having a pair of outlet side portions (14-1, 14-2) connected to both sides of the outlet body portion via a third fold line (C21) and connected to the inner body portion via a second cut line (K2), wherein the region of the outlet side portion opposite to the outlet body portion is located along the inner surface of the outer body portion.A protruding portion (17) is provided on the side of the outlet opposite to the outlet body on the side opposite to the second cut line. The first cut line has a shape in which a locking portion (111K) is formed on the outer body when the first cut line is broken, and by breaking the first cut line and rotating the rotating piece portion to the outside of the outer specific surface portion via the first fold line, the outlet side portion is pulled toward the outlet body portion, causing the second cut line to break. After the second cut line is broken, further rotation of the rotating piece portion causes the protruding portion of the outlet side portion to lock into the locking portion, and the outlet, consisting of the rotating piece portion and the outlet forming portion, becomes open.

[0011] In the first configuration of the packaging box, the second cut line is broken by breaking the first cut line and rotating the rotating piece portion to the outside of the outer specific surface portion via the first fold line. After the second cut line is broken, further rotation of the rotating piece portion causes the protruding portion on the side of the dispensing opening to engage with the locking portion, and the dispensing opening, which consists of the rotating piece portion and the dispensing opening forming portion, opens up. As a result, the product stored in the inner box portion can be removed without removing the outer box portion.

[0012] Secondly, in the first configuration described above, when the protruding portion of the outlet side engages with the notch and the outlet is opened, the outlet body and the outlet side form an obtuse angle, and the pair of outlet sides form an inverted V shape when viewed from the outside of the outlet.

[0013] Therefore, the main body of the dispensing opening and the side of the dispensing opening form an obtuse angle, and the pair of side parts of the dispensing opening form an inverted V shape when viewed from the outside of the dispensing opening, so that the dispensing opening is wide open and products can be easily taken out.

[0014] Thirdly, in the first configuration described above, the outlet side portion has an intermediate region (15) connected to the outlet body portion via a third bend line, and an end region (16) connected to the intermediate region via a fourth bend line (C22) formed from the base end of the third bend line, and the protruding portion is provided at the end portion of the end region opposite to the intermediate region, and when the outlet is in the open state, the outlet body portion and the intermediate region form an obtuse angle, and the intermediate region and the end region form an obtuse angle.

[0015] Therefore, when the dispensing opening is in the open position, the main body of the dispensing opening and the intermediate region form an obtuse angle, and the intermediate region and the end region also form an obtuse angle, so the dispensing opening opens wider, making it easier to take out the products.

[0016] Furthermore, fourthly, in any of the configurations described in the first to third above, the outer specific surface portion is characterized in that it is at least two of the four surface portions: the outer front portion, the outer right side portion, the outer left side portion, and the outer rear portion, and the inner specific surface portion is characterized in that it is a surface portion along the outer specific surface portion among the four surface portions: the inner front portion, the inner right side portion, the inner left side portion, and the inner rear portion.

[0017] Furthermore, in the fifth configuration, the bottom portion is formed by a one-touch bottom and has a first bottom portion (60) connected from the lower edge of the inner right side portion, a second bottom portion (70) connected from the lower edge of the inner front portion, a third bottom portion (80) connected from the lower edge of the inner back portion, and a fourth bottom portion (90) connected from the lower edge of the inner left side portion, and the first bottom portion consists of the first bottom portion and the second bottom portion. One of the pair, the first specific bottom portion (70), has a first main body (72) connected to the inner sleeve-shaped portion and a first sub-body (74), which is the other side portion of the pair of first bottom portion pieces, and the first sub-body is bendable relative to the first main body via a fold line, and the first sub-body is bonded to the other side of the pair of first bottom portion pieces, and the second specific bottom portion (80), which is one of the pair of second bottom portion pieces consisting of a third bottom portion and a fourth bottom portion, is attached to the inner sleeve-shaped portion. It has a second main body portion (82) connected to the bulge-shaped portion, and a second sub-body portion (84) which is the other side portion of the second bottom portion pair, the second sub-body portion is bendable relative to the second main body portion via a fold line, the second sub-body portion is bonded to the other side of the second bottom portion pair, a first partition portion (95) is connected to the side of the first main body portion opposite to the inner sleeve-shaped portion, and a second partition portion (97) is connected to the side of the second main body portion opposite to the inner sleeve-shaped portion. The inner specific surface portion is one of four surface portions: the inner front portion, the inner right side portion, the inner left side portion, and the inner back portion, specifically the surface portion (10) connected to the first main body portion and the surface portion (40) connected to the second main body portion. By expanding the inner sleeve-shaped portion and the outer sleeve-shaped portion to assemble the bottom portion, the surfaces on both sides of the first partition portion and the surfaces on both sides of the second partition portion face the two inner specific surface portions, thereby dividing the space between the two inner specific surface portions.

[0018] Therefore, since the space inside the inner box portion can be partitioned by the first partition portion and the second partition portion, the products in the space on the side of the surface portion closer to the surface portion than the first partition portion and the second partition portion can be taken out from the surface portion continuously provided from the first main body portion and the outlet provided on the outer surface portion of the outer box portion, and the products in the space on the side of the surface portion closer to the surface portion than the first partition portion and the second partition portion can be taken out from the surface portion continuously provided from the second main body portion and the outlet provided on the outer surface portion of the outer box portion.

Effect of the Invention

[0019] According to the packaging box based on the present invention, by breaking the first cut line and rotating the rotating piece portion to the outside of the outer specific surface portion via the first fold line, the second cut line is broken, and after the second cut line is broken, by further rotating the rotating piece portion, the protruding portion on the outlet side portion is locked to the locking portion, and the outlet formed by the rotating piece portion and the outlet forming portion is in an open state, so that the products stored in the inner box portion can be taken out without removing the outer box portion.

[0021] In this invention, the objective of providing a packaging box in which the goods stored in the inner box can be removed without removing the outer box is achieved as follows: the packaging box comprises a bottom portion, an inner box portion having an inner sleeve-like portion, and an outer box portion covering the inner box portion, the outer box portion having an outer sleeve-like portion with outer side portions corresponding to each inner side portion that constitutes the inner sleeve-like portion.

[0022] The packaging box P according to the present invention is configured as shown in Figures 1 to 9, and has an inner box A and an outer box B, each of which is formed from a single sheet-like blank (specifically corrugated cardboard (especially double-sided corrugated cardboard), but cardboard or the like may also be used).

[0023] The inner box section A has a container shape with the top open overall, and as shown in Figures 5 and 6, it has a sleeve-shaped section (inner sleeve-shaped section) 1, a bottom section 50, and partition sections 95 and 97.

[0024] In its assembled state, the sleeve-shaped portion 1 is formed by standing upright around the bottom portion 50 and has a front portion (inner front portion) 10, a side portion (inner right side portion) 20, a side portion (inner left side portion) 30, a back portion (inner back portion) 40, and an adhesive portion 49. Its unfolded state is formed as shown in Figure 5.

[0025] Here, as shown in Figure 6, the front section 10 has a main body section (inner main body section) 11 and an outlet forming section 12 connected to the upper side of the main body section 11 via a folded line (second folded line) C20 and a pair of cut lines K1 and K2.

[0026] The main body portion 11 forms the base of the front portion 10 and is connected via fold lines from the second piece portion 70 of the side portions 20, 30 and the bottom portion 50. The main body portion 11 has a horizontally elongated shape, with the left and right sides and the bottom edge of the main body portion 11 formed in a straight line, and the top edge of the main body portion 11 formed in an uneven shape for connection via fold lines C20 and cut lines K1, K2. This main body portion 11 is connected from the side portions 20 and 30, which are adjacent surfaces of the sleeve-shaped portion 1.

[0027] The outlet forming section 12 is connected to the upper edge of the main body section 11 via a fold line C20 and cut lines K1 and K2. The outlet forming section 12 has an outlet main body section 13 connected via a fold line C20 in the horizontal direction (i.e., parallel to the lower edge of the main body section 11), and outlet side sections 14-1 and 14-2 connected to the left and right sides of the outlet main body section 13 via a fold line (third fold line) C21. Specifically, outlet side section 14-1 is connected to the right side of the outlet main body section 13 (right side in front view) via fold line C21, and outlet side section 14-2 is connected to the left side of the outlet main body section 13 (left side in front view) via fold line C21.

[0028] The outlet body portion 13 has a shape enclosed by a bent line C20, a straight cut line K1 formed diagonally upward in a tapered shape from both ends of the bent line C20, a bent line C21 formed upward from the upper end of the cut line K1, and an upper edge 13a formed between the upper ends of a pair of bent lines C21. The pair of cut lines K1 are tapered such that the length between the pair of cut lines K1 increases as they go upward. The bent line C21 has a straight bent line C21a formed from the upper end of the cut line K1, and a straight bent line C21b formed from the upper end of the bent line C21a to the upper edge 13a of the outlet body portion 13. The pair of bent lines C21a are tapered such that the length between the pair of bent lines C21a decreases as they go upward, and the pair of bent lines C21b are formed parallel to each other and perpendicular to the lower edge of the body portion 11. This outlet body portion 13 is glued to the rotating piece portion 112 of the outer box portion B.

[0029] Next, since the outlet side portion 14-1 and the outlet side portion 14-2 are formed symmetrically, let us take the outlet side portion 14-1 as an example. The outlet side portion 14-1 has an intermediate region 15 connected to the right side of the outlet main body portion 13 via a broken line C21, and an end region 16 connected to the right side of the intermediate region 15 via a broken line (fourth broken line) C22.

[0030] The intermediate region 15 is an intermediate region between the outlet body portion 13 and the end region 16, and has a shape enclosed by a broken line C21, a straight broken line C22 formed diagonally upward from the upper end of the cut line K1, and a side portion between the upper end of broken line C21 and the upper end of broken line C22. This side portion consists of a substantially arc-shaped side portion 15a connected from the end of the upper side 13a, a straight side portion 15b formed downward from side portion 15a, and a horizontal straight side portion 15c.

[0031] The pair of bent lines C22, consisting of bent line C22 at outlet side 14-1 and bent line C22 at outlet side 14-2, are tapered such that the length between the pair of bent lines C22 increases as you go upwards. Furthermore, bent line C22 is formed from the base end of bent line C21, and bent line C22 and bent line C21a form an acute angle, so the intermediate region 15 is generally formed in a roughly elongated fan shape.

[0032] The end region 16 has a shape enclosed by a straight edge 16a formed on the extension of edge 15c, an edge 16b formed diagonally downward from edge 16a, an edge 16c formed in a roughly mountain shape from edge 16b, a straight edge 16d formed diagonally downward from edge 16c, a straight edge 16e formed diagonally downward from edge 16d, an edge 16f formed in a roughly arc shape from edge 16e, and a broken line C22 formed between edge 16a and edge 16f, wherein the angle of edge 16e with respect to the horizontal is smaller than the angle of edge 16d with respect to the horizontal.

[0033] A cut line (second cut line) K2 is provided between the end region 16 and the main body 11 (that is, the end region 16 is connected to the main body 11 via the cut line K2), and the cut line K2 is provided along the edges 16d, 16e, and 16f. When the outlet main body 13 is rotated via the bend line C20, the outlet side portion 14-1 is pulled in the direction of rotation, but because the main body portion 111 of the front portion 110 of the outer box B is located outside the end region 16 (see Figure 4), the outlet side portion 14-1 is pulled towards the outlet main body 13 (more precisely, the end region 16 is pulled towards the outlet main body 13), causing the cut line K2 to break. When the cut line K2 breaks, it breaks from the end on the edge portion 16f side.

[0034] Furthermore, a protruding portion 17 is provided in the end region 16 by the edge portion 16c. In other words, the protruding portion 17 is provided at the end position opposite to the outlet body portion 13 on the upper edge (the edge opposite to the cut line K2 side) of the outlet side portion 14-1 (that is, the protruding portion 17 is provided at the end portion of the end region 16 opposite to the intermediate region 15), and the protruding portion 17 is in a roughly triangular shape that protrudes diagonally upward.

[0035] The outlet side portion 14-2 has a left-right symmetrical configuration with the outlet side portion 14-1, and the outlet side portion 14-2 has an intermediate region 15 connected to the left side of the outlet main body portion 13 via a broken line C21, and an end region 16 connected to the left side of the intermediate region 15 via a broken line C22.

[0036] The configuration of the intermediate region 15 and the end region 16 in the outlet side portion 14-2 is the same as that of the intermediate region 15 and the end region 16 in the outlet side portion 14-1, except that it is symmetrical, so a detailed explanation is omitted.

[0037] Furthermore, the side portion 20 is connected to the right side edge of the front portion 10 via a broken line C3, and has a shape in which a trapezoidal shape is superimposed on the upper part of a rectangular shape.

[0038] Furthermore, the side portion 30 is connected to the left side edge of the front portion 10 via a broken line C2, and has a shape in which a trapezoidal shape is superimposed on the upper part of a rectangular shape.

[0039] Furthermore, the rear section 40 is connected to the rear edge of the side section 30 via a folded line C1. The rear section 40 has the same configuration as the front section 10, and as shown in Figure 6, the rear section 40 has a main body section 11 and an outlet forming section 12 connected to the upper side of the main body section 11 via a folded line C20 and a pair of cut lines K1 and K2.

[0040] The main body portion 11 forms the base of the back portion 40 and is connected to the side portion 30, the adhesive portion 49, and the third piece 80 of the bottom portion 50 via a fold line. The configuration of the main body portion 11 is the same as that of the main body portion 11 in the front portion 10, so a detailed explanation is omitted.

[0041] The outlet forming section 12 has the same configuration as the outlet forming section 12 in the front section 10, and as shown in Figure 6, it is connected to the upper edge of the main body section 11 via a fold line C20 and cut lines K1 and K2. The outlet forming section 12 has an outlet main body section 13 connected via a fold line C20 in the horizontal direction (i.e., parallel to the lower edge of the main body section 11), and outlet side sections 14-1 and 14-2 connected to the left and right sides of the outlet main body section 13 via fold lines C21. Specifically, outlet side section 14-1 is connected to the right side of the outlet main body section 13 (right side in rear view) via fold line C21, and outlet side section 14-2 is connected to the left side of the outlet main body section 13 (left side in rear view) via fold line C21.

[0042] Furthermore, the outlet side portion 14-1 has an intermediate region 15 connected to the right side of the outlet main portion 13 via a broken line C21, and an end region 16 connected to the right side of the intermediate region 15 via a broken line C22. The outlet side portion 14-2 has an intermediate region 15 connected to the left side of the outlet main portion 13 via a broken line C21, and an end region 16 connected to the left side of the intermediate region 15 via a broken line C22.

[0043] The configuration of the outlet body 13 and outlet side portions 14-1 and 14-2 is the same as that of the outlet body 13 and outlet side portions 14-1 and 14-2 in the front section 10. Furthermore, the intermediate region 15 and end region 16 in the outlet side portions 14-1 and 14-2 are the same as those of the intermediate region 15 and end region 16 in the outlet side portions 14-1 and 14-2 in the front section 10, so a detailed explanation is omitted.

[0044] Furthermore, the adhesive margin 49 is connected to the left end of the back portion 40 in a rear view via a fold line C0, and has a long, narrow, trapezoidal shape in the vertical direction. The outer surface of this adhesive margin 49 is adhered to the inner surface of the rear end region of the side portion 20.

[0045] In the sleeve-shaped portion 1, of the four surfaces—the front surface 10, the side surfaces 20, the side surfaces 30, and the back surface 40—the front surface 10 and the back surface 40, which are the surfaces on which the main body portion 11 and the outlet forming portion 12 are provided, become the inner specific surfaces. Furthermore, the front surface 10 and the back surface 40, which are the inner specific surfaces, are surfaces connected to the main body portions 72 and 82, on which the partition portions 95 and 97 are connected. Thus, by unfolding the sleeve-shaped portion 1 and the sleeve-shaped portion 101 to assemble the bottom surface portion 50, the partition portions 95 and 97 are erected in the left-right direction, and the surfaces on both sides of the partition portion 95 and the surfaces on both sides of the partition portion 97 face the front surface 10 and the back surface 40, thereby dividing the space between the front surface 10 and the back surface 40.

[0046] Furthermore, the bottom portion 50 is a so-called one-touch bottom, and has a first piece (first bottom portion) 60, a second piece (second bottom portion) 70, a third piece (third bottom portion) 80, and a fourth piece (fourth bottom portion) 90, and in the assembled state of the packaging box P, it has a roughly rectangular shape (see Figure 3).

[0047] Here, the first piece 60 is connected to the lower end of the side portion 20 via a fold line and is formed in a roughly trapezoidal shape that narrows towards the tip, with a part of its upper surface forming a part of the inner bottom surface of the inner box portion A. In the assembled state of the bottom portion 50, the first piece 60 is formed in a roughly point-symmetric manner with respect to the center position of the fourth piece 90 and the bottom portion 50 (the intersection of two straight lines connecting the diagonal corners of the bottom portion 50). However, in the first piece 60, a notch 60K is provided at the tip so as not to interfere with the protruding portion 83 of the third piece 80 when the bottom portion 50 is assembled.

[0048] Furthermore, the second section 70 is connected to the lower end of the front section 10 via a fold line and is formed in a roughly rectangular shape, with a part of the upper surface of the second section 70 forming a part of the inner bottom surface of the inner box section A. Also, a fold line 70-1 (this fold line 70-1 is a mountain fold on the upper side) is formed diagonally from the corner of the second section 70 (the lower end of the boundary between the front section 10 and the side section 20) relative to the edge that forms the boundary between the second section 70 and the front section 10, so that the inner box section A can be easily folded. The second section 70 is divided into a main body section (first main body section) 72 and a sub-body section (first sub-body section) 74 via the fold line 70-1. The tip of the main body portion 72 has a side portion parallel to the lower edge of the front portion 10, and the tip of the main body portion 72 on the side of the sub-body portion 74 has a notch portion 72a formed so as to lock with the other main body portion 82. In addition, the tip edge of the main body portion 72 has a roughly mountain-shaped projection portion 73 adjacent to the notch portion 72a (adjacent to the side opposite to the sub-body portion 74), making it easier to maintain the locked state when the main body portion 72 locks with the main body portion 82. In particular, since the partition portion 95 is connected to the main body portion 72, the projection portion 73 is provided to strengthen the locked state between the main body portion 72 and the main body portion 82. The upper surface of the sub-body portion 74 is bonded to the lower surface of the first piece portion 60.

[0049] Furthermore, the third section 80 is connected to the lower end of the back section 40 via a fold line and is formed in a roughly rectangular shape, with a part of the upper surface of the third section 80 forming a part of the inner bottom surface of the inner box section A. Also, a fold line 80-1 is formed diagonally from the corner of the third section 80 (the lower end of the boundary between the back section 40 and the side section 30) relative to the edge that forms the boundary between the third section 80 and the back section 40 (this fold line 80-1 is a mountain fold on the upper side), so that the inner box section A can be easily folded. The third section 80 is divided into a main body section (second main body section) 82 and a sub-body section (second sub-body section) 84 via the fold line 80-1. The tip of the main body portion 82 has a side parallel to the lower edge of the back portion 40, and the tip of the main body portion 82 on the side of the sub-body portion 84 has a notch 82a formed so as to engage with the other main body portion 72. In addition, the tip edge of the main body portion 82 has a roughly mountain-shaped projection 83 adjacent to the notch 82a (adjacent to the side opposite to the sub-body portion 84), making it easier to maintain the engaged state when the main body portion 82 engages with the main body portion 72. In particular, the projection 83 is provided in the same way as the projection 73 of the second piece portion 70 because the partition portion 97 is connected to the main body portion 82. The upper surface of the sub-body portion 84 is bonded to the lower surface of the fourth piece portion 90.

[0050] Furthermore, the fourth piece 90 is connected to the lower end of the side portion 30 via a fold line and is formed in a roughly trapezoidal shape that narrows towards the tip, with a part of its upper surface forming a part of the inner bottom surface of the inner box portion A. The fourth piece 90 has the same configuration as the first piece 60, and in the fourth piece 90, a notch 90K is provided at the tip so as not to interfere with the protruding portion 73 of the second piece 70 when the bottom portion 50 is assembled.

[0051] Furthermore, the partition section (first partition section) 95 is connected to the front edge of the main body section 72 (the edge parallel to the lower edge of the front section 10) via a broken line, and has a roughly rectangular shape.

[0052] Furthermore, the partition section (second partition section) 97 is connected to the front edge of the main body section 82 (the edge parallel to the lower edge of the back section 40) via a fold line and has a roughly rectangular shape.

[0053] The partitions 95 and 97 are erected in the left-right direction relative to the bottom surface 50 by assembling the bottom surface 50.

[0054] Furthermore, the partition portion 95 is formed to protrude in the left-right direction beyond the end of the notch portion 72a (the end opposite to the sub-body portion 74) toward the sub-body portion 74, and the partition portion 97 is formed to protrude in the left-right direction beyond the end of the notch portion 82a (the end opposite to the sub-body portion 84) toward the sub-body portion 84. As a result, when the bottom portion 50 is assembled and the partition portions 95 and 97 are erected, the partition portions 95 and 97 overlap. That is, when the ends of the notch portion 72a and the notch portion 82a are located at the center position in the left-right direction of the bottom portion 50 when the bottom portion 50 is assembled, the partition portions 95 and 97 protrude beyond the ends of the notches 72a and 82a, causing the partition portions 95 and 97 to overlap (see Figure 9). As a result, no gap is formed between the partition 95 and the partition 97, and the product does not move between the spaces partitioned by the partition 95 and the partition 97.

[0055] As described above, in the bottom portion 50, the second portion (first specific portion of the bottom portion) 70, which is one of the first pair of bottom portion portions consisting of the first portion 60 and the second portion 70, has a main body portion (first main body portion) 72 connected from the sleeve-shaped portion 1 and a sub-body portion (first sub-body portion) 74, which is the other side of the first pair of bottom portion portions, and the sub-body portion 74 is bendable relative to the main body portion 72 via a fold line, and the sub-body portion 74 is the other portion of the first pair of bottom portion portions 6 The third piece (second specific piece of the bottom surface) 80, which is one of the bottom surface second piece pair consisting of a third piece 80 and a fourth piece 90, is bonded to 0 and has a main body (second main body) 82 connected to the sleeve-shaped part 1 and a sub-body (second sub-body) 84 which is the other side of the bottom surface second piece pair, and the sub-body 84 is bendable relative to the main body 82 via a fold line and is bonded to the fourth piece 90, which is the other side of the bottom surface second piece pair.

[0056] In the unfolded state of the inner box section A, the lower edge of the front section 10 (the lower edge of the main body section 11), the lower edge of the side section 20, the lower edge of the side section 30, and the lower edge of the back section 40 are formed on the same straight line, and these lower edges constitute the lower edge of the sleeve-shaped section 1.

[0057] Furthermore, the folded lines C0 to C3 in the inner box portion A are formed parallel to each other and perpendicular to the lower edge of the sleeve-shaped portion 1.

[0058] When the inner box section A is assembled into a box shape, the front section 10 and the back section 40 are parallel to each other, the side sections 20 and 30 are parallel to each other, and each component constituting the bottom section 50 is approximately perpendicular (or may be perpendicular) to the front section 10, side sections 20 and 30, and back section 40. In other words, the sleeve-shaped section 1 is perpendicular (or may be approximately perpendicular) to the bottom section 50. Also, adjacent components of each component constituting the sleeve-shaped section 1 (front section 10, side sections 20 and 30, and back section 40) are perpendicular (or may be approximately perpendicular) to each other.

[0059] Furthermore, the inner box section A can be folded into a flat shape. In the inner box section A, by reducing the angle between the front section 10 and the side section 20 (i.e., making it smaller than a right angle), and by reducing the angle between the back section 40 and the side section 30 (i.e., making it smaller than a right angle), the rectangular cylindrical sleeve section 1 becomes flattened, and each part constituting the bottom section 50 rotates within the sleeve section 1, allowing the inner box section A to be folded into a flat shape as a whole. When the inner box section A is folded, each part constituting the bottom section 50 is approximately parallel to the front section 10, side sections 20, 30, and back section 40 that constitute the sleeve section 1 within the sleeve section 1. The partition section 95 extends upward from the tip of the main body section 72 of the second piece section 70, and the partition section 97 extends upward from the tip of the main body section 82 of the third piece section 80.

[0060] Next, the outer box B is a box that covers the inner box A, and as shown in Figures 1, 2, 7, and 8, it has a sleeve-shaped part (outer sleeve-shaped part) 101, a lid part 160, and flap parts 170, 180, and 190, and its unfolded state is formed as shown in Figure 7.

[0061] Here, the sleeve-shaped portion 101, when assembled, has a rectangular cylindrical shape and includes a front portion (outer front portion) 110, a side portion (outer right side portion) 120, a side portion (outer left side portion) 130, a back portion (outer back portion) 140, and an adhesive portion 149.

[0062] Here, the front section 110 has a rectangular shape, and its lateral length (the length between the folded line C12 and the folded line C13) is formed to be slightly larger than the lateral length of the front section 10 so that the inner box section A can be accommodated.

[0063] Furthermore, the front portion 110 has a main body portion (outer main body portion) 111 connected to the side portions 120, 130 and the lid portion 160 via a folded line, and a rotating piece portion 112 and a pressing piece portion 114 formed on the inside of the main body portion 111 (see Figure 8).

[0064] Here, the main body portion 111 has a rectangular outer shape, and exhibits a frame shape obtained by removing the areas of the rotating piece portion 112 and the pressing piece portion 114 from the rectangular shape. In other words, the shape of the main body portion 111 itself is such that it has an opening consisting of the areas of the rotating piece portion 112 and the pressing piece portion 114. This main body portion 111 is connected to the adjacent surfaces of the sleeve-shaped portion 101, namely the side portions 120 and 130.

[0065] Furthermore, as shown in Figure 8, the rotating piece 112 is provided in the inner region of the main body 111 and is connected to the main body 111 via a bent line C30 provided along the lower edge of the inner side of the main body 111 (the lower edge of the opening) and cut lines (first cut lines) K10 connected from both ends of the bent line C30, and has a shape enclosed by the bent line C30 and the cut lines K10. In other words, it is formed circumferentially by the bent line C30 and the cut lines K10.

[0066] The broken line C30 is formed in a straight line parallel to the lower edge of the front portion 110 and is also formed parallel to the broken line C20. The cut line K10 has a pair of cut lines K11 formed diagonally upward from the left and right ends of the broken line C30, a cut line K12 formed diagonally downward inward from the upper end of the cut line K11, a cut line K13 formed upward (more precisely, diagonally upward) from the inner end of the cut line K12, and a cut line K14 formed horizontally between the upper ends of the pair of cut lines K13. The broken line C30 is parallel to the broken line C20 on the front portion 10.

[0067] The pair of cutting lines K11 are formed in a tapered shape, with the length between the pair of cutting lines K11 increasing as you go upwards, and each cutting line K11 is formed along a straight line (virtual straight line) that is angled upwards.

[0068] Furthermore, the pair of cut lines K12 are tapered, with the length between the pair of cut lines K12 decreasing as you go downwards, and each cut line K12 is formed in a nearly straight shape.

[0069] Furthermore, the pair of cut lines K13 are formed in a tapered shape, with the length between the pair of cut lines K13 decreasing as you go upwards, and each cut line K13 is formed along a straight line (virtual straight line) that is angled upwards. In addition, the cut line K14 is formed in a roughly straight shape that curves upwards.

[0070] Furthermore, as shown in Figure 8, the pressing piece 114 is connected to the upper inner edge of the main body 111 (the upper edge in the opening) via a folded line C31, and has a roughly rectangular shape enclosed by the folded line C31, a pair of cut lines K15 formed downward from both ends of the folded line C31, and a part of the cut line K14.

[0071] The positional relationship between the rotating piece portion 112 and the pressing piece portion 114 in the outer box portion B and the outlet forming portion 12 in the inner box portion A is as shown in Figure 4. In a front view, the outlet main body portion 13 and the intermediate region 15 are within the area of ​​the rotating piece portion 112, and the end region 16 (i.e., the region on the opposite side of the outlet main body portion 13 in the outlet side portion 14-1) is located along the inner surface of the main body portion 111 (i.e., on the back side of the main body portion 111), except for the region along the broken line C22 between it and the intermediate region 15. This is also true when the back portion 140 and the back portion 40 are viewed from the back.

[0072] In the rotating piece portion 112 and the pressing piece portion 114, by pressing the pressing piece portion 114 with a finger to rotate it via the fold line C31, and then hooking a finger onto the upper end of the rotating piece portion 112 and pulling it towards the user, the cut line K10 breaks, causing the rotating piece portion 112 to rotate towards the user via the fold line C30.

[0073] Furthermore, since the cutting lines K11 and K12 form an acute angle, the cutting lines K11 and K12 form a notch 111K (see Figure 8). When the rotating piece 112 is rotated forward and the outlet forming part 12 forms an outlet, the protruding part 17 of the end region 16 engages with this notch 111K. In other words, the cutting line K10 has a shape (i.e., a notch shape) that, when the cutting line K10 is broken, forms a notch (locking part) 111K in the main body 111 that engages with the protruding part 17.

[0074] Note that the cutting line K10 is formed entirely by the planned cutting line, each of the cutting lines K11, K13, and K14 is formed by the planned cutting line, and cutting lines K12 and K15 are formed by continuous cuts.

[0075] Furthermore, the side portion 120 is connected to the right side edge of the front portion 110 via a broken line C13, and has a rectangular shape. The lateral length of the side portion 120 (the length between broken lines C13 and C14) is slightly longer than the lateral length of the side portion 20.

[0076] Furthermore, the side portion 130 is connected to the left side edge of the front portion 110 via a broken line C12, and has a rectangular shape. The lateral length of the side portion 130 (the length between broken lines C11 and C12) is slightly longer than the lateral length of the side portion 30.

[0077] Furthermore, the rear portion 140 is connected to the rear side of the side portion 130 via a broken line C11, and the lateral length of the rear portion 140 is formed to be slightly larger than the lateral length of the rear portion 40.

[0078] The rear portion 140 has a main body portion 111 connected to the side portion 130 and the flap portion 190 via a folded line, and a rotating piece portion 112 and a pressing piece portion 114 formed in the inner region of the main body portion 111.

[0079] Here, the main body portion 111 has a roughly rectangular outer shape, and exhibits a frame shape obtained by removing the areas of the rotating piece portion 112 and the pressing piece portion 114 from the rectangular shape, and a protruding portion and a notch are formed in the upper end region to form the insertion portion 192. In other words, the main body portion 111 on the back portion 140 has a shape that has an opening consisting of the areas of the rotating piece portion 112 and the pressing piece portion 114, similar to the main body portion 111 on the front portion 110 (see Figure 8).

[0080] Furthermore, the rotating piece portion 112 has the same configuration as the rotating piece portion 112 in the front portion 110, and as shown in Figure 8, it is provided in the inner region of the main body portion 111 and is connected to the main body portion 111 via a bent line C30 provided along the lower edge portion of the inner side of the main body portion 111 (the lower edge portion of the opening) and a cut line (first cut line) K10 connected from both ends of the bent line C30, and has a shape enclosed by the bent line C30 and the cut line K10. In other words, it is formed circumferentially by the bent line C30 and the cut line K10. The configuration of the rotating piece portion 112 in the rear portion 140 is the same as the rotating piece portion 112 in the front portion 110, so a detailed explanation is omitted.

[0081] Furthermore, the pressing piece portion 114 has the same configuration as the pressing piece portion 114 in the front portion 110, and as shown in Figure 8, it is connected via a folded line C31 from the upper inner edge portion (the upper edge portion in the opening) of the main body portion 111, and has a roughly rectangular shape enclosed by the folded line C31, a pair of notches K15 formed downward from both ends of the folded line C31, and a part of the cut line K14. The configuration of the pressing piece portion 114 in the back portion 140 is the same as the pressing piece portion 114 in the front portion 110, so a detailed explanation is omitted.

[0082] Furthermore, the adhesive margin 149 is connected to the back end of the side portion 120 via a fold line C14 and has a long, narrow, trapezoidal shape in the vertical direction. As shown in Figure 2, the inner surface of this adhesive margin 149 is adhered to the outer surface of the back portion 140.

[0083] In the sleeve-shaped portion 101, of the four surfaces—the front portion 110, the side portion 120, the side portion 130, and the back portion 140—the front portion 110 and the back portion 140, which are the surfaces on which the main body portion 111 and the rotating piece portion 112 are provided, are designated outer surfaces. The front portion 10, which is designated as an inner surface, is the surface that lies along the inner surface of the front portion 110, which is designated as an outer surface, and the back portion 40, which is designated as an inner surface, is the surface that lies along the back portion 140, which is designated as an outer surface.

[0084] Furthermore, the vertical lengths of the front section 110, the side sections 120 and 130, and the back section 140 are formed to be approximately the same, and are formed to be slightly larger than the vertical length of the inner box section A. In other words, the vertical length of the sleeve-shaped section 101 of the outer box section B is formed to be larger than the vertical length (maximum length) of the sleeve-shaped section 1 of the inner box section A. When the outer box section B is unfolded, the lower edge of the front section 110, the lower edge of the side section 120, the lower edge of the side section 130, and the lower edge of the back section 140 are formed on the same straight line.

[0085] Furthermore, the lid portion 160 is connected to the upper end of the front portion 110 via a folded line and has a lid body 162 connected to the front portion 110 and an insertion piece 164 formed to protrude from the tip of the lid body 162.

[0086] The lid body 162 is roughly rectangular in shape and is sized to cover the sleeve-shaped portion 101 when it is open in a cylindrical shape. The insertion piece 164 is connected to the front edge of the lid body 162 via a fold line, and the insertion piece 164 is inserted into the insertion portion 192 provided between the back portion 140 and the flap portion 190.

[0087] Furthermore, the flap portion 170 is connected to the upper end of the side portion 120 via a fold line and has a roughly rectangular shape.

[0088] Furthermore, the flap portion 180 is connected to the upper end of the side portion 130 via a fold line and has a roughly rectangular shape.

[0089] Furthermore, the flap portion 190 is connected to the upper end of the back portion 140 via a fold line and has a shape in which a trapezoidal shape is superimposed on the upper part of a rectangular shape.

[0090] These lid portions 160 and flaps 170-190 open and close the top surface of the outer box portion B. The lid portion 160 and flaps 170-190 can be closed by folding flaps 170 and 180 inward, folding flap portion 190 inward, and further folding the lid body 162 inward and inserting the insertion piece 164 into the insertion part 192. As shown in Figures 1 and 2, the lid portion 160 and flaps 170-190 are initially erected upwards, leaving the top of the outer box portion B open.

[0091] In the packaging box P, the dispensing opening 200 is formed by the rotating piece 112 of the outer box B and the dispensing opening forming part 12 of the inner box A. In other words, dispensing openings 200 are provided on the front and back sides of the packaging box P (see Figures 10 and 11). Note that the dispensing opening 200 is in a closed state before the rotating piece 112 is rotated forward.

[0092] When the outer box section B is assembled into a box shape, the front section 110 and the back section 140 are parallel to each other, and the side sections 120 and 130 are parallel to each other. In addition, adjacent members of each component constituting the sleeve-shaped section 101 (front section 110, side sections 120 and 130, and back section 140) are at right angles (or nearly right angles) to each other.

[0093] Furthermore, the inner box A and the outer box B are bonded together at the front section 10 and the outlet main section 13 of the back section 40. In other words, the outer surface of the outlet main section 13 of the front section 10 and the inner surface of the rotating piece 112 of the front section 110 are bonded together, and the outer surface of the outlet main section 13 of the back section 40 and the inner surface of the rotating piece 112 of the back section 140 are bonded together.

[0094] Furthermore, when the inner box A and the outer box B are glued together, the lower end of the inner box A and the lower end of the outer box B are formed to be at the same height. Note that the inner box A and the outer box B are not glued together except at the locations of the pair of outlet main bodies 13.

[0095] As described above, the inner box A is housed inside the outer box B, and all parts of the inner box A except for the bottom surface 50 are covered by the outer box B. In other words, the height of the lower end of the outer box B is approximately the same as the height of the lower end of the inner box A, and when the lid 160 is sealed, only the bottom surface 50 of the inner box A is exposed.

[0096] Furthermore, the packaging box P with the above configuration can be folded into a flat shape by aligning the front portion 110 to be approximately parallel to the side portion 120 and the side portion 130 to be approximately parallel to the back portion 140.

[0097] When using the packaging box P, the packaging box P is assembled. Specifically, the sleeve-shaped part 101 is expanded into a cylindrical shape so that the front part 110 and the back part 140 of the outer box part B are parallel to each other, and the side parts 120 and 130 are parallel to each other. The bottom part 50 is assembled by expanding the sleeve-shaped part 1 into a cylindrical shape so that the front part 10 and the back part 40 of the inner box part A are parallel to each other, and the side parts 20 and 30 are parallel to each other. The bottom part 50 is then assembled so that it is perpendicular to the sleeve-shaped parts 1 and 101, thereby assembling the packaging box P into a three-dimensional shape.

[0098] When the bottom section 50 is assembled, the partition sections 95 and 97 are erected relative to the bottom section 50. That is, as shown in Figure 9, both the partition section 95 and the partition section 97 are erected in the left-right direction, with partition section 95 located on the side section 30 side and partition section 97 located on the side section 20 side, and the area of ​​partition section 95 opposite to the side section 30 and the area of ​​partition section 97 opposite to the side section 20 overlap. These partition sections 95 and 97 are provided between the front section 10 and the back section 40, and are provided to partition the space between the front section 10 and the back section 40.

[0099] Once the packaging box P is assembled, multiple products (items to be stored) are placed inside the inner box A from the top of the packaging box P. To store the products inside the inner box A, the products are placed in the spaces on the front and back sides of the partitions 95 and 97. After storing the products, the lid 160 and flaps 170-190 are closed to close the outer box B.

[0100] Next, we will explain how to open the dispensing opening 200 and remove the product stored in the inner box A from the dispensing opening 200. The method for opening the dispensing opening 200 on the front side and the dispensing opening 200 on the back side of the packaging box P is the same, so we will explain how to open the dispensing opening 200 on the front side.

[0101] First, by pressing the pressing piece 114 with a finger and rotating it via the fold line C31, and then hooking a finger onto the upper end of the rotating piece 112 and pulling it towards you, the cut line K10 breaks, and the rotating piece 112 rotates towards you via the fold line C30.

[0102] As a result, the outlet body portion 13, which is bonded to the rotating piece portion 112, rotates forward via the fold line C20, and the outlet side portions 14-1 and 14-2 are pulled in the direction of rotation. However, since the main body portion 111 of the front portion 110 of the outer box portion B is located outside the end region 16, the end region 16 is pulled towards the intermediate region 15, and the pair of cut lines K2 break.

[0103] Furthermore, by rotating the pivot piece 112 forward, the upper edge of the end region 16 comes into contact with the notch 111K of the main body 111, and the end region 16 is pulled out along the edge of the main body 111 that follows the cut line K11. The protruding portion 17 of the end region 16 then engages with the notch 111K, causing the front-side dispensing opening 200 to open, as shown in Figures 10, 12, and 13. The pair of dispensing side portions 14-1 and 14-2 form an inverted V shape when viewed from the outside of the dispensing opening 200, as shown in Figure 12. Because the dispensing side portions 14-1 and 14-2 form an inverted V shape, the dispensing opening 200 opens wide, making it easier to take out products.

[0104] Furthermore, when the dispensing opening 200 is in the open position, as shown in Figure 12, the dispensing opening body 13 and the intermediate region 15 form an obtuse angle, and the intermediate region 15 and the end region 16 also form an obtuse angle, so the dispensing opening 200 opens wider, making it easier to take out products.

[0105] When the front-side dispensing opening 200 is opened, the product can be removed from the inner box A through the dispensing opening 200. In other words, the product stored in the space in front of the partitions 95 and 97 can be removed through the dispensing opening 200 located on the front side of the packaging box P.

[0106] Furthermore, the method for opening the rear outlet 200 of the packaging box P is the same as the method for opening the front outlet 200 described above, so a detailed explanation will be omitted. Note that opening the rear outlet 200 results in the configuration shown in Figures 11, 12, and 13.

[0107] When the rear opening 200 is opened, products stored in the space behind the partitions 95 and 97 can be removed.

[0108] In other words, the sides of the partitions 95 and 97 face the front section 10 and the back section 40, dividing the space between the front section 10 and the back section 40. Therefore, the partitions 95 and 97 divide the space inside the inner box A into a front section and a back section, allowing products from the front section to be taken out from the front opening 200 and products from the back section to be taken out from the back opening 200.

[0109] As described above, with packaging box P, the goods stored in inner box A can be removed without removing outer box B. In other words, in packaging box P having a bottom portion 50, an inner box A having a sleeve-shaped portion 1, an outer box B covering inner box A, an outer box B having a sleeve-shaped portion 101 with outer side portions (front portion 110, side portions 120, 130, and back portion 140) corresponding to each inner side portion (front portion 10, side portions 20, 30, and back portion 40) that constitute the sleeve-shaped portion 1, and a lid portion 160, the work of removing outer box B is unnecessary, and the goods stored in inner box A can be removed without removing outer box B.

[0110] In the above description, the inner box A is provided with an outlet forming section 12 on the front section 10 and the back section 40, and the second section 70 and the third section 80 are configured to have a main body section 72, 82 and a sub-body section 74, 84, and the second section 70 and the third section 80 are provided with partition sections 95, 97, and the outer box B is provided with a rotating section 112 and a pushing section 114 on the front section 110 and the back section 140. Although this configuration is described, the inner box A shown in Figure 5 and the outer box B shown in Figure 7 may be configured symmetrically, with outlet forming sections on the side sections 20 and 30, and the first piece 60 and the fourth piece 90 having a main body and a sub-body, with partition sections on the first piece 60 and the fourth piece 90, and in the outer box B, a rotating piece and a pushing piece may be provided on the side sections 120 and 130.

[0111] In the sleeve-shaped section 1, the four surfaces—the front section 10, the side sections 20, the side sections 30, and the back section 40—are divided into two surfaces: the front section 10 and the back section 40, where the main body section 11 and the outlet forming section 12 are provided. Similarly, in the sleeve-shaped section 101, the four surfaces—the front section 110, the side sections 120, the side sections 130, and the back section 140—are divided into two surfaces: the front section 110 and the back section 140, where the main body section 111 and the rotating piece section 112 are provided. However, in the inner box section A and the outer box section B, there may be one surface or three or more surfaces. In other words, in the four surfaces—the front, the right side, the left side, and the back—an outlet may be provided on one surface, or outlets may be provided on three surfaces. In that case, partitioning the space inside the inner box section A is unnecessary, so partition sections 95 and 97 are not provided.

[0112] Furthermore, when dispensing openings are provided on two sides, the openings may be provided on adjacent sides. For example, the front and right sides may have dispensing openings. In this case as well, the partitions 95 and 97 shall not be provided. [Explanation of Symbols]
