Description

[Technical field]

[0001] The present invention relates to a box for displaying products, and more particularly to a box in which part of the side can be used for POP advertising. [Background technology]

[0002] The applicant has filed an application for a packaging box in Patent Document 1, which is used for packaging a collection of multiple products and displaying them at stores, etc. That is, Patent Document 1 discloses a packaging box having a substantially rectangular bottom surface portion 50, an inner sleeve-like portion erected from each side of the bottom surface portion and forming a substantially right angle with the bottom surface portion, a sleeve-like portion 5 consisting of a front surface portion 10, a pair of opposing side surfaces 20, 30, and a back surface portion 40, an inner box portion with an open top, in which parts of the side surfaces 20, 30 are formed as separation portions 24, 34 in the pair of opposing side surfaces so as to be separable from the main body portions 22, 32, which are the parts of the side surfaces other than the separation portions, via a cut line having perforations, and an inner box portion A1 formed from a single blank, and an outer box portion covering the inner box portion, which corresponds to each of the front surface portion 110, the pair of side surfaces 120, 130, and the back surface portion 140 constituting the sleeve-like portion of the inner box portion, and the sleeve-shaped portion 105 having a front portion 110 formed along the outer surface of the front portion 10, side portions 120, 130 formed along the outer surfaces of each of the side portions of a pair of side portions 20, 30, respectively, and a back portion 140 formed along the outer surface of the back portion 40; and an outer box portion A2 formed from a single blank, the outer box portion having a lid portion connected to the upper end of the sleeve-shaped portion 105 via a fold line, the inner box portion having a separation portion bonded to the side portion corresponding to the side portion on which the separation portion is provided, and the areas of the side portions 120, 130 to which the separation portions 24, 34 are bonded are formed so as to be breakable from other portions of the side portions 120, 130.

[0003] Furthermore, the front part 10 of the inner box part A1 has a protruding display part 14. The protruding display part 14 has a connecting part 14a connected to the side part 20, display part main bodies 14b, 14c, and a locking part 14d, and can be protruded to the front side in a state where the display part main bodies 14b, 14c overlap by locking the locking part 14d to the right end part of the main body part 12 when viewed from the front. In this way, by making the protruding display part 14 a shape related to the product or by displaying an advertisement for the product, it is possible to strongly inform visitors of the product stored in the packaging box.

[0004] In particular, by having the display main bodies 14b, 14c protrude vertically toward the front side relative to the front surface 10, the display main bodies 14b, 14c can be easily noticed by those viewing them from either side (the right or left direction) of the display main bodies 14b, 14c, thereby enhancing the effectiveness of the POP advertising.

[0005] Furthermore, Patent Document 2 discloses a packaging box with a display function, which can achieve a POP advertising function by having a display section protrude vertically toward the front side relative to the front section.

[0006] In the packaging box of the second embodiment (Figures 4 to 6) of Patent Document 2, the display section 10 is a flap-like portion connected via the upper part of one side of the front wall 1, and a cut 9 runs from the upper part of the front wall 1, across one side, across the lower part, and connects to a cut 12 in the other side wall 2. A diagonal line 21 is made in the base of display unit 10 extending from the front edge to the side edge, and an insertion hole 22 is formed in the front of one of the side walls 2. When the product is to be displayed in a storefront, lid 7 is opened and cut along cut line 23, then cut lines 9 and 12 are cut to remove the front wall 1 and the upper part of the other side wall 2. After that, the triangular area having diagonal line 21 as one side is folded back against side wall 2, and display unit 10 is twisted and folded along diagonal line 21. The base of display unit 10 is inserted into insertion hole 22 in side wall 2, and extension piece 24 at the lower base end of display unit 10 is inserted into cut 25 at the front of side wall 2, thereby causing display unit 10 to protrude vertically toward the front side of front wall 1. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Utility Model Registration No. 3147086 [Patent Document 2] Patent No. 4125070 Summary of the Invention [Problem to be solved by the invention]

[0008] However, with the packaging boxes of Patent Documents 1 and 2, it was not possible to display products without using the display portion (protruding display portion 14 or display portion 10), and there was a problem in that it was not possible to choose whether or not to use the display portion.

[0009] For example, in the packaging box of Patent Document 1, when the protruding display portion 14 is not used, the protruding display portion 14 occupies the upper area of ​​the front portion 10, and therefore there is a problem that the protruding display portion 14 gets in the way and makes it difficult to see the displayed products.

[0010] Furthermore, in the display-equipped packaging box of Patent Document 2, products cannot be displayed unless the display unit 10 is assembled and protrudes from the front side.

[0011] Furthermore, the packaging box with a display function of Patent Document 2 has a problem that the operation of assembling the display unit 10 is troublesome. That is, after cutting along the cuts 9 and 12 and removing the upper parts of the front wall 1 and the other side wall 2, a triangular region having the diagonal line 21 as one side must be folded back against the side wall 2, and the display unit 10 must be bent in a twisted manner along the diagonal line 21, and its base must be inserted into the insertion hole 22 in the side wall 2. After removing the upper parts of the front wall 1 and the other side wall 2, at least a step of folding back the triangular region against the side wall 2 and a step of bending the display unit 10 in a twisted manner along the diagonal line 21 are required, and further, an operation of inserting the base of the triangular region into the insertion hole 22 and inserting the extension piece 24 into the cut 25 is required.

[0012] Therefore, the present invention aims to provide a box body in which a display unit having POP advertising functions can be protruded vertically from the front side of the box body, allowing the user to choose whether or not to use the display unit as POP advertising, and even when the display unit is not used as POP advertising, the display unit does not get in the way of product display, and when the display unit is used as POP advertising, the operation of assembling the display unit is easy.

[0032] The present invention provides a packaging box in which a display unit having a POP advertising function can be protruded vertically from the front side of the packaging box, allowing a choice between using the display unit as POP advertising or not, and even when the display unit is not used as POP advertising, the display unit does not get in the way of product display, and when the display unit is used as POP advertising, the display unit can be easily assembled. This object is achieved in the following manner.

[0033] The packaging box P based on the present invention is configured as shown in Figures 1 to 9, etc., and has an inner box part A and an outer box part B, with the inner box part A and the outer box part B each being formed from a single sheet-like blank (specifically, cardboard (particularly double-sided cardboard), but it may also be thick paper, etc.).

[0034] The inner box part (box body) A is generally container-shaped with an open top, and as shown in Figures 4 to 6, etc., has a sleeve-shaped part (inner sleeve-shaped part) 1 and a bottom part 50. In the assembled state, the sleeve-shaped part 1 is formed standing from the periphery of the bottom part 50, and has a front part (inner front part) 10, side parts (inner side part, right side part, inner left side part) 20, side parts (inner side part, specific inner side part, specific side part, left side part, inner left side part) 30, a back part (inner back part) 40, and a glue tab part 49, and is formed in an unfolded state as shown in Figures 6 to 8.

[0035] Here, the front portion 10 has a shape that is roughly horizontally elongated and rectangular with a portion of it protruding upward, and has a front portion main body 12 and a protruding display portion reinforcement portion 110 that protrudes upward from the front portion main body 12 via a cut line 110K.

[0036] The front body 12 has a horizontally elongated, generally rectangular shape, with a protruding end region on the left side surface side. That is, the upper side of the front body 12 has a straight side portion 12a connected to the side portion 30a of the side surface portion 30, a straight side portion 12b connected to the side portion 12a via a rounded portion, and a straight side portion 12c connected to the side portion 12b via a rounded portion, the side portions 12a and 12c being parallel to the lower side of the front body 12, and the side portion 12b being perpendicular to the lower side of the front body 12. The rounded portion is generally arc-shaped (the same applies to the rounded portions described below).

[0037] In addition, the protruding display reinforcement portion 110 has an overall hook-like shape and has a narrow portion 112 connected to the front main body 12 via a cut line 110K, and a wide portion 114 connected to the tip of the narrow portion 112.

[0038] Narrow width portion 112 has a vertically long, generally rectangular shape, and has protrusion 116 protruding on the right side surface side. Protrusion 116 is provided at a position that is linearly symmetrical with protrusion 136 in protruding display portion 130 across an imaginary line along fold line C1 when inner box part A is in an unfolded state. Note that protrusion 136 is formed smaller than protrusion 136 so that protrusion 116 does not protrude from the outline of protrusion 136 (described later) when protrusion display portion reinforcement part 110 is adhered to protruding display portion 130.

[0039] The protruding display portion reinforcement portion 110 has a shape surrounded by a straight side portion 110a, a straight side portion 110b connected to the upper end of side portion 110a via a rounded portion, a straight side portion 110c connected to the right end of side portion 110b via a rounded portion, a straight side portion 110d connected to the lower end of side portion 110c via a rounded portion, a straight side portion 110e connected to the left end of side portion 110d via a rounded portion, a curved side portion 110f connected to the lower end of side portion 110e, a straight side portion 110g connected to the lower end of side portion 110f, and a straight side portion 110h connected to the lower end of side portion 110g via a rounded portion and connected to the lower end of side portion 110a via a rounded portion. Here, side portion 110a, side portion 110c, side portion 110e, and side portion 110g are formed in the vertical direction (perpendicular to the lower side of front portion main body 12), and side portion 110b, side portion 110d, and side portion 110h are formed parallel to the lower side of front portion main body 12. In addition, protrusion portion 116 is formed by curved side portion 110f.

[0040] Further, a fold line (inclined fold line) C110 is formed in the narrow width portion 112, and a folding ruled line (inclined ruled line) is formed along the fold line C110. The fold line C110 is formed so as to cross the narrow width portion 112 from the side portion 110a to the side portion 110g, and is formed in a straight line inclined downward from the left side surface side to the right side surface side. The fold line C110 is provided at a position that is line-symmetrical with the fold line (inclined fold line, inclined ruled line) C130 in the protruding display portion 130 with respect to a virtual line along the fold line C1 when the inner box part A is in an unfolded state. Note that the folding ruled line does not have to be formed from the side portion 110a to the side portion 110g, and may be formed in a part of the section from one end to the other end of the fold line C110. The protruding display reinforcement portion 110 is divided by a folding line C110 into a reinforcement main body 110-1, which is a region on the tip side, and a base end portion 110-2, which is a region on the base side.

[0041] The cut line 110K is substantially L-shaped and is composed of a cut line 110K-1 along the side 12b, a cut line 110K-2 along a part of the side 12c, and a cut line along the rounded portion between the side 12b and the side 12c, and for the protruding display part reinforcement part 110, the cut line 110K is formed along the lower end part of the side 110a, the side 110h, and the rounded portion between them. In this way, the protruding display part reinforcement part 110 is in contact with both the side 12b and the side 12c of the front part main body 12 via the cut line 110K, so that the wobble of the protruding display part reinforcement part 110 relative to the front part main body 12 can be reduced, and the protruding display part 130 and the protruding display part reinforcement part 110 can be correctly bonded when manufacturing the packaging box P.

[0042] 11 is bonded to the side surface portion 30, a reinforcement portion main body 110-1 (region on the tip side of the fold line C110) of the protruding display portion reinforcement portion 110 is bonded to the protruding display portion 130, and a base end portion 110-2 (region on the base side of the fold line C110) is bonded to the protruding portion 142 (described later). When the protruding display portion reinforcement portion 110 is bonded to the protruding display portion 130 and the protruding portion 142, the fold line C110 is aligned with the fold line C130, and for example, in the state of FIGS. 4 and 5, the fold line C110 and the fold line C130 coincide with each other in a side perspective view.

[0043] Furthermore, when the sleeve-shaped part 1 is spread out and the inner box part A is assembled into a box shape, the score line 110K is broken and the protruding display part reinforcing part 110 is in a state of being adhered to the protruding display part 130 and the protruding part 142. This will be described in more detail later.

[0044] Further, the wide portion 114 has a substantially rectangular shape, is formed to be wider in the lateral direction than the narrow portion 112, and has a shape that protrudes toward the right side surface.

[0045] The vertical length of the front portion 10, that is, the length from the bottom edge of the front portion main body 12 to the side 110b of the protruding display portion reinforcement portion 110, is approximately the same as the length L40 from the bottom edge to the top edge of the rear portion 40.

[0046] Next, the side surface portion 20 is connected to the end portion on the right side surface side of the front surface portion main body 12 via a fold line C2, and has an approximately rectangular shape overall, with a part of the upper front side of the square shape cut out. That is, the side surface portion 20 has a vertically elongated cutout portion 20K on the front side, and the side surface portion 20 has a straight side portion 20a connected to the side portion 12c of the front surface portion main body 12, and a straight side portion 20b connected to the side portion 20a via a rounded portion and connected to the side portion 20c, which is the upper side of the side surface portion 20, via a rounded portion, and the cutout portion 20K is formed by the side portion 20a, the rounded portion between the side portion 20a and the side portion 20b, and the side portion 20b. The side portion 20a and the side portion 20c are formed parallel to the lower side of the side surface portion 20, and the side portion 20b is formed at a right angle to the lower side of the side surface portion 20. The side surface portion 20 has a main body portion 22 and a separation portion 24. The main body portion 22 is the area of ​​the side surface portion 20 other than the separation portion 24.

[0047] Separation section 24 is an area defined by score lines 24a formed on side section 20, and score lines 24a include arcuate score lines 24a-1 and 24a-3 spaced apart in the horizontal direction (score lines 24a-1 and 24a-3 are formed symmetrically with respect to each other) and horizontal linear score line 24a-2 connecting the upper end of score line 24a-1 with the upper end of score line 24a-3. Also, at the lower end of separation section 24, there is provided cutout portion 25 having a substantially horizontal rectangular shape connected to cutout portion 72K of second piece 70 of bottom surface portion 50, and cutout portion 25 makes it easy to hook a finger on the lower end of separation section 24 when rotating pivot piece 224 of outer box part B.

[0048] Separation part 24 is formed in an area on the back side of rotating piece 224 of outer box part B, and is adhered to the back side of rotating piece 224, and is formed so that by rotating the lower end of rotating piece 224 outward and upward, separation part 24 is cut along cut line 24a while still adhered to the back side of rotating piece 224, and separation part 24 is separated from main body part 22. Separation part 24 is formed smaller than rotating piece 224, and the outer shape of separation part 24 does not protrude beyond the outer shape of rotating piece 224 in a side see-through view.

[0049] As described above, a part of the side surface portion 20 serves as the separation portion 24 and can be separated from the main body portion 22, which is the area of ​​the side surface portion 20 other than the separation portion 24, via the cut line 24a.

[0050] Next, the side surface portion (specific inner side surface portion) 30 is connected to the end portion on the left side surface side of the front surface portion main body 12 via a fold line C1, has a shape that is approximately rectangular overall, and has a shape in which a part of the upper front side of the square shape is cut out. That is, the side surface portion 30 has a vertically elongated notch portion 30K on the front surface side, and the side surface portion 30 has a straight side portion 30a connected to the side portion 12a of the front surface portion main body 12, and a straight side portion 30b connected to the side portion 30a via a round portion and connected to the side portion 30c-1 constituting the upper side of the side surface portion 30 via a round portion, and the notch portion 30K is formed by the side portion 30a, the round portion between the side portion 30a and the side portion 30b, and the side portion 30b. The side portion 30a and the side portion 30c-1 are formed parallel to the lower side of the side surface portion 20, and the side portion 30b is formed at a right angle to the lower side of the side surface portion 30. The side surface portion 30 has a main body portion 32 and a separation portion 34. The main body portion 32 is the area of ​​the side surface portion 30 other than the separation portion 34.

[0051] Separation section 34 is an area defined by score lines 34a formed on side surface section 30, and score lines 34a include arcuate score lines 34a-1 and 34a-3 spaced apart in the horizontal direction (score lines 34a-1 and 34a-3 are formed symmetrically with respect to each other) and horizontal linear score line 34a-2 connecting the upper end of score line 34a-1 with the upper end of score line 34a-3. Also, at the lower end of separation section 34, substantially horizontally rectangular cutout portion 35 is provided which is connected to cutout portion 82K of third piece 80 of bottom surface section 50, and cutout portion 35 makes it easy to hook a finger onto the lower end of separation section 34 when rotating pivot piece 234 of outer box part B.

[0052] Separation portion 34 is formed in an area on the back side of rotating piece 234 of outer box part B, and is adhered to the back side of rotating piece 234, and is formed so that by rotating the lower end of rotating piece 234 outward and upward, separation portion 34 is cut along cut line 34a while still adhered to the back side of rotating piece 234, and separation portion 34 is separated from main body part 32. Separation portion 34 is formed smaller than rotating piece 234, and the outer shape of separation portion 34 does not protrude beyond the outer shape of rotating piece 234 in a side see-through view.

[0053] Furthermore, separation section 34 is provided in a position that is symmetrical to separation section 24 when inner box part A is in an assembled state.

[0054] As described above, a part of the side surface portion 30 serves as the separation portion 34 and can be separated from the main body portion 32, which is the area of ​​the side surface portion 30 other than the separation portion 34, via the cut line 34a.

[0055] In addition, in the main body 32, a fold line C130 and a cut line 130K are formed, which are connected to the end of the fold line C130 on the rear side, and the fold line C130 and the cut line 130K divide the main body 32 into the protruding display portion 130 and the main body main constituent portion 140. The cut line 130K is formed between the end of the fold line C130 on the rear side and the side portion 30c, which is the upper side of the side surface portion 30, and the region above the fold line C130 becomes the protruding display portion 130. If the region consisting of the main body main constituent portion 140 and the separation portion 34 is the main body 33 (see FIG. 6), the main body 33 is the region of the side surface portion 30 other than the protruding display portion 130, and the side surface portion 30 is divided into the protruding display portion 130 and the main body 33 by the fold line C130 and the cut line 130K, and the region above the fold line C130 becomes the protruding display portion 130.

[0056] Here, the fold line C130 is formed as a straight line that slopes downward from an end s, which is a midway point from the bottom end to the top end of the side portion 30b, toward the back side, and the angle α of the fold line C130 with respect to the direction of the bottom side of the side portion 30 is 45 degrees (or may be approximately 45 degrees). A folding line (slanted line) is formed along this fold line C130.

[0057] The cut line 130K includes a straight cut line 130K-1 formed from the upper end of the main body 32 (strictly speaking, the lower end of the notch between the side 30c-1 and the side 30c-2), a straight cut line 130K-2 formed from the lower end of the cut line 130K-1 via a rounded portion, a straight cut line 130K-3 connected from the end of the cut line 130K-2 on the front side via a rounded portion, a curved cut line 130K-4 connected from the lower end of the cut line 130K-3, and a cut line 130K-5 formed from the lower end of the cut line 130K-4 to the end t on the back side of the folded line C130. In other words, it can be said that the cut line 130K is connected from the end on the back side of the folded line C130. Although the folding lines are formed from end s to end t, they do not necessarily have to be formed from end s to end t, and may be formed in a part of the section from end s to end t.

[0058] The cut lines 130K-1, 130K-3, and 130K-5 are formed in the vertical direction (perpendicular to the lower side of the side portion 30), and the cut line 130K-2 is formed in the horizontal direction (parallel to the lower side of the side portion 30).

[0059] The curved cut line 130K-4 is formed in a shape corresponding to the side portion 110f of the protruding display portion reinforcing portion 110, and a protruding portion 136 is formed in the protruding display portion 130 by this cut line 130K-4.

[0060] Furthermore, a hook-shaped cut line 131K is connected to the lower end of the cut line 130K-5, which extends downward and then bends toward the rear side. This cut line 131K is formed to prevent the cut line 130K-5 from accidentally breaking at the lower end when breaking the cut line 130K.

[0061] As a result, the protruding display portion 130 includes a side portion 130a which is an upper portion of the end portion s of the side portion 30b, a side portion 30c-1 connected to the side portion 130b via a rounded portion, a straight side portion 130b connected to the side portion 30c-1 via a rounded portion, a straight side portion 130c connected to the side portion 130b via a rounded portion, a straight side portion 130d connected to the side portion 130c via a rounded portion, and a curved side portion connected from the lower end of the side portion 130d. The side portion 130b is formed along the cutting line 130K-1, the side portion 130c is formed along the cutting line 130K-2, the side portion 130d is formed along the cutting line 130K-3, the side portion 130e is formed along the cutting line 130K-4, and the side portion 130f is formed along the cutting line 130K-5. The side portions 130b, 130d, and 130f are formed in the vertical direction (perpendicular to the lower side of the side portion 30), and the side portion 130c is formed in the horizontal direction (parallel to the lower side of the side portion 30).

[0062] Since the protruding display portion 130 is formed as described above, the protruding display portion 130 has a narrow portion 132 formed above the folded line C130 and a wide portion 134 connected to the tip of the narrow portion 132.

[0063] The narrow width portion 132 has a generally vertically long rectangular shape, and has a protruding portion (locking portion) 136 that protrudes from the left side surface.

[0064] Further, the wide portion 134 has a substantially rectangular shape, is formed to be wider than the narrow portion 132, and has a shape that protrudes toward the left side surface.

[0065] In addition, the length L1 from the end t on the rear side of the fold line C130 to the edge portion 30c-1 that constitutes the upper edge of the side portion 30 is formed longer than the length L2 in the front-to-rear direction between the end t and the fold line C1 (see Figure 8), thereby allowing the protruding display portion 130 to protrude from the front portion main body 12 to the front side when the protruding display portion 130 is folded back via the fold line C130.

[0066] Also, in order to allow the protruding portion 136 to engage with the side portion 30a (the upward-facing side portion) when the protruding display portion 130 is folded back at the fold line C130, the length L3 from the end portion t to the lower end of the side portion 130e is longer than the length L4 from the end portion t to the side portion 30b (see FIG. 8), and the length L5 from the end portion t to the upper end of the side portion 130e is shorter than the length L2. However, if it is sufficient that the tip of the protruding portion 136 is engaged with at least the side portion 30a, it is sufficient that the length L6 from the end portion t to the intermediate position between the upper end and the lower end of the side portion 130e (a position equidistant from the upper end and the lower end in the vertical direction) is longer than the length L4 and shorter than the length L2.

[0067] Furthermore, in order to prevent side portion 130b, which is the lower edge of wide portion 134, from contacting the placement surface of inner box portion A when protruding display portion 130 is folded back along fold line C130, the front-to-rear length L7 between side portion 130b and sides 130d, 130f is formed shorter than the length L8 from end portion t to the lower edge of side portion 30 (see Figure 8).

[0068] The main body component 140 is an area of ​​the main body 32 other than the protruding display portion 130, and the main body component 140 has a right-angled triangular protruding portion 142 at a position between the lower end of the cut line 130K and the side portion 30a, and the folded line C130 is formed along the upper side of the protruding portion 142. In other words, the protruding portion 142 has a side portion along the folded line C130, and the side portion 30a (upward side portion) is provided adjacent to the protruding portion 142 on the front side of the protruding portion 142. The side portion 30c-2 which is the upper side of the main body component 140 and the side portion 30c-1 of the protruding display portion 130 are formed on the same straight line, and both are formed parallel to the lower side of the side portion 30. The side portion 30c which is the upper side of the side portion 30 is formed by the side portion 30c-1 and the side portion 30c-2.

[0069] In addition, the horizontal length of side portion 30 (the length between fold lines C0 and C1) is formed to be the same (or may be approximately the same) as the horizontal length of side portion 20 (the length between fold lines C2 and C3).

[0070] The protruding display portion 130 is bonded to the protruding display portion reinforcement portion 110, and the protruding display portion 130 and the protruding display portion reinforcement portion 110 together form the protruding display unit 105 (see Figs. 5, 20 to 22). In the protruding display unit 105, the protruding portion 136 and the protruding portion 116 are in an overlapping state, and the protruding portion 136 and the protruding portion 116 form the locking portion 106. Note that the protruding display portion 130 is bonded to an area on the tip side of the folding line C110 of the protruding display portion reinforcement portion 110, as shown in Fig. 11.

[0071] The side portion 30 is formed as described above, and the overall shape of the side portion 30 is formed symmetrically with the side portion 20, except for the presence of the fold line C130, the cut lines 130K, 131K, and the difference in height between the side portions 30a and 20a, making the presence of the protruding display unit 105 less noticeable when the protruding display unit 105 is not in use.

[0072] The rear portion 40 is connected to the rear end of the side portion 20 via a fold line C3, and has an overall rectangular shape. The lateral length of the rear portion 40 (i.e., the length between the fold line C3 and the side of the rear portion 40 opposite to the fold line C3) is formed to be the same (or may be approximately the same) as the lateral length of the front portion 10 (i.e., the length between the fold lines C1 and C2).

[0073] The vertical length of the back surface portion 40, the vertical length (maximum length) of the front surface portion 10, and the vertical lengths (maximum lengths) of the side surface portions 20, 30 are formed to be the same.

[0074] The adhesive portion 49 is connected to the end of the side surface portion 30 on the rear side via a folding line C0, and has a vertically elongated belt-like trapezoid shape. The outer surface of the adhesive portion 49 is bonded to the inner surface of the end region on the rear side of the side surface portion 30.

[0075] The bottom surface portion 50 is a so-called one-touch bottom, and has a first piece (first piece of the bottom surface portion) 60, a second piece (second piece of the bottom surface portion) 70, a third piece (third piece of the bottom surface portion) 80, and a fourth piece (fourth piece of the bottom surface portion) 90. In the assembled state of the packaging box P, as shown in FIG. , and has a roughly rectangular outer shape.

[0076] Here, the first piece 60 is connected to the lower end of the front part 10 via a fold line, and is formed in a generally trapezoidal shape that narrows toward the tip, and a part of its upper surface forms a part of the inner bottom surface of the inner box part A. In the assembled state of the bottom part 50, this first piece 60 is formed generally point symmetrically with respect to the center position of the fourth piece 90 and the bottom part 50 (the intersection of two straight lines connecting the diagonal corners of the bottom part 50), but the first piece 60 is provided with a cutout 60K so as not to interfere with the protruding display part reinforcement part 110 when the folded sleeve-shaped part 1 is unfolded to assemble the inner box part A. This cutout 60K is formed so that the two sides constituting the cutout 60K are aligned with the sides 110g and 110h of the protruding display part reinforcement part 110 in the state of FIG. 15 (when the inner box part A is folded), and the two sides are at right angles to each other.

[0077] The second piece 70 is connected to the lower end of the side surface 20 via a fold line and is formed in a generally rectangular shape, with a part of the upper surface of the second piece 70 forming a part of the inner bottom surface of the inner box part A. A fold line 70-1 (the fold line 70-1 has a mountain fold on the upper surface side) is formed from a corner of the second piece 70 (the lower end of the boundary position between the side surface 20 and the back surface 40) obliquely to the side that forms the boundary between the second piece 70 and the front surface 10, so that the inner box part A can be easily folded. The second piece 70 is divided into a main body part 72 and a tip part 74 via the fold line 70-1. A notch 72a is formed on the tip side of the tip of the main body part 72 on the tip part 74 side so as to engage with the other main body part 82. The upper surface of the tip part 74 is bonded to the lower surface of the fourth piece 90.

[0078] Main body portion 72 has a band-shaped cutout 72K along the boundary with side surface portion 20, and when inner box part A is in an unfolded state, cutout 72K and cutout 25 form a convex opening. This cutout 72K makes it easy to hook a finger on the lower end of rotating piece 224 or the lower end of separation part 24.

[0079] The third piece 80 is connected to the lower end of the side surface portion 30 via a fold line, and is formed in point symmetry with respect to the center position of the second piece 70 and the bottom surface portion 50 when the bottom surface portion 50 is assembled. That is, the third piece 80 is connected to the lower end of the side surface portion 30 via a fold line, and is formed in a substantially rectangular shape, and a part of the upper surface of the third piece 80 forms a part of the inner bottom surface of the inner box part A. In addition, a fold line 80-1 (the fold line 80-1 has a mountain fold on the upper surface side) is formed from a corner of the third piece 80 (the lower end of the boundary position between the front surface portion 10 and the side surface portion 30) obliquely with respect to the side portion that forms the boundary between the third piece 80 and the side surface portion 30, so that the inner box part A can be easily folded. The third piece 80 is divided into a main body portion 82 and a tip portion 84 via the fold line 80-1. A notch 82a is formed on the tip end 84 side of the tip of the main body 82 so as to engage with the other main body 72. The upper surface of the tip end 84 is bonded to the lower surface of the first piece 60.

[0080] A band-shaped cutout 82K is provided in main body portion 82 along the boundary with side surface portion 30, and when inner box part A is in an unfolded state, cutout 82K and cutout 35 form a convex opening. This cutout 82K makes it easy to hook a finger on the lower end of rotating piece 234 or the lower end of separation part 34.

[0081] In addition, the fourth arm 90 is connected to the lower end of the back portion 40 via a fold line and is formed into an approximately trapezoidal shape that narrows toward the tip, and part of its upper surface forms part of the inner bottom surface of the inner box portion A.

[0082] As described above, in the bottom portion 50, the tip portion (first end region) 84, which is the other side portion of one of the bottom portion first piece pair, which are two adjacent pieces (first piece 60 and third piece 80), can be bent via a fold line, and the tip portion 84 is adhered to the first piece 60, and the tip portion (second end region) 74, which is the other side portion of one of the bottom portion second piece pair, which are the other two adjacent pieces (second piece 70 and fourth piece 90), can be bent via a fold line, and the tip portion 74 is adhered to the fourth piece 90.

[0083] In addition, when the inner box part A is in an unfolded state, the lower edge of the front part 10 (the lower edge of the front part main body 12), the lower edge of the side part 20, the lower edge of the side part 30, and the lower edge of the back part 40 are formed on the same straight line, and these lower edges constitute the lower edge of the sleeve-shaped part 1.

[0084] Moreover, the fold lines C0 to C3 in the inner box part A are formed parallel to one another and perpendicular to the lower side of the sleeve-shaped part 1.

[0085] When the inner box part A is assembled into a box shape, the front part 10 and the back part 40 are parallel to each other, the side part 20 and the side part 30 are parallel to each other, and each member constituting the bottom part 50 is at a substantially right angle (may be a right angle) to the front part 10, the side parts 20, 30, and the back part 40. In other words, the sleeve-shaped part 1 is at a substantially right angle (may be a right angle) to the bottom part 50. In addition, adjacent members among the members constituting the sleeve-shaped part 1 (the front part 10, the side parts 20, 30, and the back part 40) are at a right angle (may be at a substantially right angle) to each other.

[0086] Moreover, inner box part A can be folded into a flat plate (see Figures 13 to 15), and by making the angle between front part 10 and side part 30 in inner box part A small (i.e. smaller than a right angle) and making the angle between back part 40 and side part 20 small (i.e. smaller than a right angle), the square tubular sleeve-shaped part 1 becomes flattened and the parts that make up bottom part 50 rotate into sleeve-shaped part 1, allowing inner box part A to be folded into a flat plate as a whole. When inner box part A is in a folded state, the parts that make up bottom part 50 are approximately parallel to front part 10, side parts 20, 30 and back part 40 that make up sleeve-shaped part 1 within sleeve-shaped part 1.

[0087] Next, the outer box part B is a box body which covers the inner box part A, and as shown in Figures 1 to 3, 9, etc., it has a sleeve-shaped part (outer sleeve-shaped part) 201, flap parts 260, 290, and lid parts 270, 280, and its unfolded state is formed as shown in Figure 9.

[0088] Here, when assembled, the sleeve-shaped portion 201 has a rectangular tubular shape and has a front portion (outer front portion) 210, a side portion (outer side portion, right side portion, outer right side portion) 220, a side portion (outer side portion, left side portion, outer left side portion) 230, a back portion (outer back portion) 240, and a glue tab portion 249.

[0089] Here, the front part 210 has a square (rectangular) plate shape. The lateral length of this front part 210 (the length between the fold lines C11 and C12) is formed slightly larger than the lateral length of the front part 10 so that the inner box part A can be stored therein.

[0090] The side surface portion 220 is connected to the end portion on the right side surface side of the front surface portion 210 via a fold line C12 and has a rectangular shape. The lateral length of the side surface portion 220 (the length between the fold lines C12 and C13) is slightly larger than the lateral length of the side surface portion 20.

[0091] Arc-shaped cut lines 224a, 224b are formed on the side surface portion 220 at intervals in the horizontal direction. The cut lines 224a, 224b are formed upward from the lower edge of the side surface portion 220, and are formed by perforated cuts (planned cutting lines). The cut lines 224a and 224b are formed symmetrically with respect to each other.

[0092] Furthermore, a fold line C224 parallel to the lower side of the side surface portion 220 is provided between the upper end of the cut line 224a and the upper end of the cut line 224b, and the area surrounded by the cut lines 224a, 224b and the fold line C224 becomes the rotating piece portion 224. The area of ​​the side surface portion 220 other than the rotating piece portion 224 becomes the main body portion (outer side surface portion main body portion) 222.

[0093] In other words, the rotating piece 224, which is a piece including the area of ​​the side surface portion 220 to which the separation portion 24 is bonded, is rotatable relative to the main body portion 222, which is the area of ​​the side surface portion 220 other than the rotating piece 224.

[0094] The side surface portion 230 is connected to the end portion on the left side surface side of the front surface portion 210 via a fold line C11 and has a rectangular shape. The lateral length of the side surface portion 230 (the length between the fold line C11 and the side portion on the opposite side of the fold line C11) is formed to be approximately the same as the lateral length of the side surface portion 30.

[0095] Arc-shaped cut lines 234a, 234b are formed on the side surface portion 230 at intervals in the horizontal direction. The cut lines 234a, 234b are formed upward from the lower edge of the side surface portion 230, and are formed by perforated cuts (planned cutting lines). The cut lines 234a and 234b are formed symmetrically with respect to each other.

[0096] Furthermore, a fold line C234 parallel to the lower side of the side surface portion 230 is provided between the upper ends of the cut lines 234a and 234b.

[0097] In other words, the rotating piece 234, which is a piece including the area of ​​the side surface portion 230 to which the separation portion 34 is bonded, is rotatable relative to the main body portion 232, which is the area of ​​the side surface portion 230 other than the rotating piece 234.

[0098] In the assembled state of outer box part B, cut lines 224a, 224b and cut lines 234a, 234b are formed symmetrically with respect to a plane, and pivot pieces 224 and 234 are also formed symmetrically with respect to a plane.

[0099] The rear portion 240 is connected to the rear end of the side portion 220 via a folding line C13 and has a rectangular shape. The width of the rear portion 240 is formed to be approximately the same as the horizontal length of the front portion 210 and is formed to be slightly larger than the horizontal length of the rear portion 40.

[0100] The adhesive portion 249 is connected to the end of the left side surface of the back surface portion 240 via a fold line C14, and has a vertically elongated belt-like trapezoid shape. As shown in FIG. 1, the adhesive portion 249 has an inner surface bonded to the outer surface of the side surface portion 230.

[0101] Furthermore, the vertical lengths of front portion 210, side portions 220, 230 and back portion 240 are all formed to be the same and slightly longer than the vertical length of inner box part A. That is to say, the vertical length of sleeve-shaped portion 201 of outer box part B is longer than the vertical length (maximum length) of sleeve-shaped portion 1 of inner box part A. When outer box part B is in an unfolded state, the bottom edge of front portion 210, the bottom edge of side portion 220, the bottom edge of side portion 230 and the bottom edge of back portion 240 are formed on the same straight line, and the top edge of front portion 210, the top edge of side portion 220, the top edge of side portion 230 and the top edge of back portion 240 are also formed on the same straight line.

[0102] In addition, the flap portion (first lid piece) 260 is connected to the upper end of the front portion 210 via a fold line, and has an approximately square shape (approximately rectangular shape) with chamfered corners on both tip sides of the rectangle.

[0103] The cover (second cover piece) 270 is connected to the upper end of the side surface portion 220 via a folding line. It has a substantially square shape (substantially rectangular shape) with the corners on both tip sides of the rectangle being chamfered.

[0104] Lid portion (third lid piece) 280 is connected to the upper end of side portion 230 via a folding line, and has a substantially square shape (substantially rectangular shape) with chamfered corners on both ends of the rectangle. Lid portion 280 is formed to have the same size and shape as lid portion 270.

[0105] The flap portion (fourth cover piece) 290 is connected to the upper end of the back surface portion 240 via a folding line and has a substantially square shape (substantially rectangular shape) with chamfered corners on both ends of the rectangle. The flap portion 290 is formed to have the same size and shape as the flap portion 260.

[0106] These lids 270, 280 and flap parts 260, 290 open and close the top surface of the outer box part B, and in particular, the top surface of the outer box part B is closed by closing the lids 270, 280. That is, the length from the base end to the tip of the lids 270, 280 is half the lateral length of the front part 210 and the back part 240, and when the lids 270, 280 are closed, the tip of the lid part 270 and the tip of the lid part 280 come into contact with each other. The lids 270, 280 and the flap parts 260, 290 are what is called an A-type. The lids 270, 280 and the flap parts 260, 290 are in advance set upright, and the top of the outer box part B is open.

[0107] In addition, a vertically long, strip-shaped opening K220 is formed below the boundary between the front portion 210 and the side portion 220, and a vertically long, strip-shaped cutout portion K230 is formed below the boundary between the front portion 210 and the side portion 230.When the inner box portion A and the outer box portion B are bonded together, the upper end of the opening K220 approximately coincides with the upper end of the boundary between the front portion 10 and the side portion 20, the upper end of the cutout portion K230 approximately coincides with the upper end of the boundary between the front portion 10 and the side portion 30, and in particular, the upper end of the cutout portion K230 engages with the upper end of the boundary between the front portion 10 and the side portion 30.

[0108] When outer box part B is assembled into a box shape, front part 210 and back part 240 are parallel to each other, and side part 220 and side part 230 are parallel to each other. Adjacent members of each member constituting sleeve-shaped part 201 (front part 210, side parts 220, 230, back part 240) form a right angle (or may form an approximately right angle) with each other.

[0109] Next, the inner box part A and the outer box part B are adhered to each other at the separation parts 24, 34. That is, the outer surface of separation part 24 is adhered to the inner surface of side part 220 (particularly, pivot piece 224) by adhesive or other adhesive means, and the outer surface of separation part 34 is adhered to the inner surface of side part 230 (particularly, pivot piece 234) by adhesive or other adhesive means, thereby forming the packaging box P as a whole as a single unit. That is, an adhesive layer (not shown) is provided between the whole or a part of the area of ​​the outer surface of separation part 24 and the inner surface of side part 220, and similarly, an adhesive layer (not shown) is provided between the whole or a part of the area of ​​the outer surface of separation part 34 and the inner surface of side part 230. As a result, the sleeve-shaped portion 201 of the outer box part B is arranged along the outer surface of the sleeve-shaped portion 1 in the inner box part A, for example, a front portion 210 is arranged along the outer surface of the front portion 10, a side portion 220 is arranged along the outer surface of the side portion 20, a side portion 230 is arranged along the outer surface of the side portion 30, and a back portion 240 is arranged along the outer surface of the back portion 40. The adhesive strength of the adhesive layer is set so that when pivot piece 224 of outer box part B is pivoted outwardly about fold line C224 as the pivot axis (i.e., pivoted upwards), the cut line 24a around separation part 24 simultaneously breaks, causing separation part 24 to separate from inner box part A and to follow pivot piece 224 while remaining adhered to the rotated pivot piece 224; and similarly, when pivot piece 234 of outer box part B is pivoted outwardly about fold line C234 as the pivot axis (i.e., pivoted upwards), the cut line 34a around separation part 34 simultaneously breaks, causing separation part 34 to separate from inner box part A and to follow pivot piece 234 while remaining adhered to the rotated pivot piece 234.

[0110] In the above example, the rotating piece is rotated upward, but the lower ends of the score lines 224a, 224b may be provided above the lower edge of the side surface portion 220, and the lower ends of the score lines 234a, 234b may be provided above the lower edge of the side surface portion 230, and fold lines serving as rotation axes may be provided at the lower ends of the score lines 224a, 224b or at the lower ends of the score lines 234a, 234b, to rotate downward. Also, the fold lines C224, C234 serving as rotation axes are formed in the horizontal direction, but this is not limited thereto, and the rotation axis may be formed in the vertical direction, and the rotating piece may be rotated in the horizontal direction.

[0111] Furthermore, when the inner packet part A and the outer packet part B are glued together, the bottom end of the inner packet part A and the bottom end of the outer packet part B are at the same height. The inner packet part A and the outer packet part B are not glued to each other except at separators 24, 34.

[0112] As described above, inner box part A is stored inside outer box part B, and all of inner box part A except for bottom part 50 is covered by outer box part B. In other words, the position in the height direction of the bottom end of outer box part B is approximately the same as the position in the height direction of the bottom end of inner box part A, and when lid parts 270, 280 are sealed, only bottom part 50 is exposed in inner box part A.

[0113] The packaging box P having the above-described configuration can be folded into a flat shape as shown in Figures 13 to 15 by aligning the front portion 210 to be approximately parallel to the side portion 230 and the side portion 220 to be approximately parallel to the back portion 240.

[0114] In the inner packet part A and the outer packet part B, folding lines are formed in advance at the locations of each fold line.

[0115] A manufacturing process for the packaging box P having the above-mentioned configuration will be described below. First, the inner box part A and the outer box part B in an unfolded state are manufactured.

[0116] Next, the outer surface of inner box part A is bonded to the inner surface of outer box part B (first bonding step). That is, with the inner surface of outer box part B in an unfolded state facing up, adhesive is applied to the bonding area of ​​pivot piece 224 with separation part 24 and the bonding area of ​​pivot piece 234 with separation part 34, and inner box part A in an unfolded state is laid over as shown in Figure 10. This bonds separation part 24 to pivot piece 224, and bonds separation part 34 to pivot piece 234. At this time, the bottom edge of sleeve-shaped part 201 of outer box part B and the bottom edge of sleeve-shaped part 1 of inner box part A are made to approximately match (or may match), and fold line C2 and fold line C12 are made to match in outer box part B and inner box part A. Incidentally, the horizontal lengths of corresponding members of sleeve-shaped portion 1 and sleeve-shaped portion 201 are longer in outer box part B, and so fold line C13 is slightly offset outward from fold line C3, and fold line C11 is slightly offset outward from fold line C1. Furthermore, because the bottom edge of sleeve-shaped portion 201 of outer box part B and the bottom edge of sleeve-shaped portion 1 of inner box part A are made to roughly coincide, when packaging box P is in an assembled state, the inner box part is not visible from the side of the outer box part, which would detract from its appearance.

[0117] Next, the various parts constituting bottom portion 50 of inner box part A are folded inwardly relative to sleeve-shaped portion 1, and further, tip portion 74 of second piece 70 is folded outwardly relative to main body portion 72, and tip portion 84 of third piece 80 is folded outwardly relative to main body portion 82, to obtain the state shown in Fig. 11 (folding step). That is, first piece 60 is folded back toward front portion 10 via the fold line at the boundary with front portion 10, second piece 70 is folded back toward side portion 20 via the fold line at the boundary with side portion 20, third piece 80 is folded back toward side portion 30 via the fold line at the boundary with side portion 30, and fourth piece 90 is folded back toward back portion 40 via the fold line at the boundary with back portion 40, and further, tip portion 74 is folded back toward main body portion 72, and tip portion 84 is folded back toward main body portion 82.

[0118] Next, adhesive is applied to the region of the first piece 60 (region shown by hatching), and adhesive is applied to the region of the protruding display part reinforcement part 110 (region shown by hatching) (adhesive application process), and the side part 230 is folded back inward toward the front part 210 side via the fold line C11 (folding back process), so that the side part 30 is folded back toward the front part 10 side via the fold line C1 to the state shown in FIG. 12. Then, the tip part 84 and the first piece 60 are bonded, and the protruding display part 130 and the protruding part 142 and the protruding display part reinforcement part 110 are bonded. Note that when applying the adhesive, it may be applied to the tip part 84 instead of the first piece 60, or it may be applied to the protruding display part 130 and the protruding part 142 instead of the protruding display part reinforcement part 110.

[0119] Next, adhesive is applied to the region of the fourth piece 90 (region shown by hatching), the region of the glue tab 49 (region shown by hatching), and the region of the glue tab 249 (region shown by hatching) (adhesive application process), and the back portion 240 is folded inwardly toward the side portion 220 via the fold line C13, and the back portion 40 is folded back toward the side portion 20 via the fold line C3, resulting in the state shown in Fig. 13. Then, the fourth piece 90 and the tip portion 74 are bonded, the glue tab 49 is bonded to the back portion 40, and the glue tab 249 is bonded to the side portion 230 (bonding process).

[0120] The adhesive may be applied to the fourth piece 90 and the overlap portions 49, 249 in the state shown in Fig. 11 before the side surface portions 230, 30 are folded back. In other words, the adhesive application process does not need to be divided into two steps, but may be performed in one step.

[0121] In addition, instead of the adhesive portion 49, adhesive may be applied to the adhesion area of ​​the back portion 40 with the adhesive portion 49, and instead of the adhesive portion 249, adhesive may be applied to the adhesion area of ​​the side portion 230 with the adhesive portion 249, and adhesive may be applied to the tip portion 74 instead of the fourth piece portion 90.

[0122] In this manner, the packaging box P is manufactured. The above-described manufacturing process is performed automatically by an assembly device.

[0123] The use state of the packaging box P having the above configuration will be described. When the packaging box P is not in use, the packaging box P can be folded into a flat plate shape, and is folded and stored. That is, since the outer box part B has the sleeve-shaped part 201 and the inner box part A has the sleeve-shaped part 1, the packaging box P can be folded into a flat plate shape, and by increasing the angle between the front part 210 and the side part 220 and the angle between the side part 230 and the back part 240, the packaging box P can be folded into a flat plate shape as shown in Figs. 13 and 14. Note that, when the packaging box P is folded and has never been unfolded and assembled, the protruding display part reinforcement part 110 is bonded to the protruding display part 130 in a state where it is connected to the front part main body 12 via the cut line 110K (see Fig. 15). Fig. 15 shows the state of the inner box part A in the packaging box P in the state of Fig. 14.

[0124] Next, when using the packaging box P, the packaging box P is assembled. That is, the packaging box P is assembled three-dimensionally by making the front portion 210 and the back portion 240 of the outer box part B parallel to each other and the side portions 220 and 230 parallel to each other, while making the front portion 10 and the back portion 40 of the inner box part A parallel to each other and the side portions 20 and 30 parallel to each other, and by expanding the sleeve-shaped portions 1, 201 so that the bottom portion 50 is at a right angle to the sleeve-shaped portions 1, 201.

[0125] Here, by spreading out the sleeve-shaped parts 1, 201 and assembling the packaging box P into a three-dimensional shape, the cut line 110K breaks and the protruding display part reinforcing part 110 is positioned on the inner surface of the protruding display part .

[0126] Then, as shown in Fig. 16, a plurality of stored items (products) G are stored in the inner box part A from above the packaging box P. Fig. 16 shows an example of bag-shaped products, but other stored items may be used. The lid parts 270, 280 and the flap parts 260, 290 are in a state of standing upright in advance, and the upper part of the outer box part B is in a state of being open, so that the stored items G can be stored as they are from above the packaging box P. Thereafter, the flap parts 260, 290 are closed, and then the lid parts 270, 280 are closed. As shown in Fig. 17, the adhesive tape T is adhered from the front part 210 of the outer box part B through the upper surface to the rear part 240 side, thereby sealing the lid parts 270, 280.

[0127] After the stored objects G are packaged in the packaging box P in the above manner, the packaging box P containing the stored objects G is transported to a location where the stored objects G are to be displayed.

[0128] Thereafter, when the stored items are to be displayed, outer box part B is separated from inner box part A. That is, pivot piece 224 of side part 220 of outer box part B is pivoted outward. That is, fold line C224 serves as a pivot axis and pivots pivot in the vertical direction. Similarly, pivot piece 234 is pivoted outward to the state shown in FIG. 18. That is, fold line C234 serves as a pivot axis and pivots in the vertical direction. Note that even if lines are not formed at the locations of fold lines C224, C234 that serve as the pivot axis when pivot pieces 224, 234 pivot, fold lines are naturally formed by pivoting pivot pieces 224, 234, but lines may be formed at the locations of the fold lines in advance.

[0129] Then, when pivoting piece 224 of outer box part B is pivoted outward, cut line 24a around separation part 24 simultaneously breaks, and separation part 24 separates from inner box part A (specifically, main body part 22) and follows pivoting piece 224 while remaining adhered to the pivoted pivoting piece 224. Similarly, when pivoting piece 234 of outer box part B is pivoted outward, cut line 34a around separation part 34 simultaneously breaks, and separation part 34 separates from inner box part A (specifically, main body part 32) and follows pivoting piece 234 while remaining adhered to the rotated pivoting piece 234.

[0130] Then, as shown in Figure 19, by pulling the outer box part B upward, the inner box part A remains with the stored item, i.e., the stored item G, stored therein and with the separation parts 24, 34 separated, so that the inner box part A is displayed with the product G stored therein.

[0131] Here, when the protruding display unit 105 is not used, the inner box part A may be used in the state shown in Figure 19 without breaking the cut line 130K, and even in this case, the protruding display unit 105 only constitutes the left side surface of the inner box part A and does not hinder the display of products. In other words, the protruding display unit 105 does not get in the way when viewing the displayed products.

[0132] Next, when the protruding display unit 105 is used by protruding it to the front side, the following procedure is followed.

[0133] That is, the protruding display unit 105 is rotated outward via the fold lines C130 and C110. That is, if the protruding display unit 105 is grabbed by hand and pulled outward, the cut line 130K will break, so the protruding display unit 105 is rotated outward (toward the left side surface) using the fold lines C130 and C110 as the rotation axis. That is, the protruding display portion 130 is folded outward relative to the main body main constituent portion 140 via the fold line C130, and the reinforcing portion main body 110-1 in the protruding display portion reinforcing portion 110 is folded outward relative to the base end portion 110-2 via the fold line C110.

[0134] Then, as shown in Figure 20, the protruding display unit 105 goes through a state inclined with respect to the horizontal and vertical planes, and the narrow portion 132 of the protruding display portion 130 and the narrow portion 112 of the protruding display portion reinforcement portion 110 (the area of ​​the reinforcement portion main body 110-1) extend laterally, and the locking portion 106 contacts the area along the side portion 30a of the main body main component 140, so that by pushing the locking portion 106 into the area along the side portion 30a, the locking portion 106 is locked in the area along the side portion 30a. In other words, when the engagement portion 106 is engaged in the area along the side portion 30a, as shown in Figures 21 and 22, the protruding display portion 130 is folded back onto the main body portion 140 via the fold line C130, and the reinforcement portion main body 110-1 in the protruding display portion reinforcement portion 110 is folded back onto the base end portion 110-2 via the fold line C110, and in the left-right direction, the protruding display unit 105 extends toward the front side at the position of the main body portion 32 that forms the wall surface on the left side side.

[0135] As a result, protruding display unit 105 protrudes vertically toward the front side relative to front body 12, and by displaying a POP advertisement on protruding display portion 130 or protruding display portion reinforcement portion 110 (particularly wide portions 114, 134), the POP advertisement can be easily noticed by those viewing from both sides (the right and left directions) of protruding display unit 105, thereby enhancing the effectiveness of the POP advertisement. In particular, when the inner box portion containing the stored items is placed on a shelf, protruding display unit 105 can protrude beyond the position of a price rail on which a price tag is to be placed and prevents items placed on the shelf from falling off, thereby making protruding display unit 105 easier to notice and enhancing the advertising effect.

[0136] Furthermore, since the protruding display unit 105 is constructed by bonding the protruding display portion 130 and the protruding display portion reinforcement portion 110 together, a POP advertisement can be printed on one side of the sheet-like blank (the outer side in the unfolded state shown in Figure 6) and the other side can be used as an adhesive surface, thereby allowing the POP advertisement to be displayed on both sides of the protruding display unit 105.

[0137] Furthermore, since the protruding display unit 105 is configured by bonding the protruding display portion 130 and the protruding display portion reinforcing portion 110 together, the protruding display unit 105 can be made strong and the protruding display unit 105 can be prevented from bending or being damaged.

[0138] Furthermore, as described above, the protruding display unit 105 can be brought into a state in which it protrudes to the front side simply by breaking the cut line 130K and rotating the protruding display unit 105, so that the operation of assembling the protruding display unit 105 becomes easy.

[0139] In addition, in the front portion 10 of the inner box part A, the protruding display part reinforcement part 110 is connected to the front portion main body 12 via the cut line 110K, and when manufacturing the packaging box P, the protruding display part reinforcement part 110 is adhered to the protruding display part 130 and the sleeve-shaped part 1 is expanded, thereby breaking the cut line 110K and allowing the protruding display part 130 and the protruding display part reinforcement part 110 to be bonded together. Therefore, when manufacturing the packaging box P, the protruding display part 130 and the protruding display part reinforcement part 110 can be easily bonded together, and by printing a POP advertisement on one side of the blank that constitutes the inner box part A, the POP advertisement can be displayed on both sides of the protruding display unit 105.

[0140] In the above description, the protruding display unit 105 is provided on the side surface part 30 on the left side surface side, but the protruding display unit may be provided on the side surface part 20 as a left-right symmetrical configuration. That is, the inner box part A in the unfolded state shown in FIG. 6 is left-right symmetrical (the outer box part B is also left-right symmetrical), the protruding display part 130 is provided on the side surface part on the right side surface side, and the protruding display part reinforcement part 110 is provided on the right side surface side of the front part 10. When using the protruding display unit provided on the side surface part 20, the protruding display unit is rotated outward (to the right side surface side) and the locking part of the protruding display unit is locked to the upward edge part of the side surface part 20. As a result, the protruding display unit is in a state of protruding to the front side at the position of the main body part 22 constituting the wall surface on the right side surface side in the left-right direction.

[0141] In the above description, the protruding display unit 105 is configured by the protruding display portion 130 and the protruding display portion reinforcement portion 110, but the configuration of the protruding display portion reinforcement portion 110 may be omitted and the configuration may be the protruding display portion 130 alone. Even in this case, the cut line 130K may be broken, and the protruding display portion 130 may be rotated via the fold line C130 to engage the protruding portion 136 with the side portion 30a. Note that when the protruding display portion reinforcement portion 110 is omitted, if a POP advertisement is printed on one side of a sheet-like blank, the POP advertisement is displayed on only one side of the protruding display portion 130, so that if a POP advertisement is displayed on both sides of the protruding display portion 130, it is necessary to display the POP advertisement on both sides of the protruding display portion 130.
