And the left-right direction (width direction intersecting (orthogonal) in the extending direction) and similar concepts.

<Blank>
As shown in FIG. 3, the blank 2 includes a pair of side walls 11, a front wall 12, a rear wall 13, a passage piece 14, a top wall 15, and a bottom wall 16. The right side wall 11, the front wall 12, the left side wall 11, the rear wall 13, and the passage piece 14 are provided in this order in a state of being connected from one to the other in the flow direction.

  The pair of side walls 11 are formed in a symmetrical shape with the front wall 12 in between. Each of the pair of side walls 11 is formed in a substantially trapezoidal shape that becomes wider in the step direction toward the direction away from the front wall 12 in the flow direction (backward). Hereinafter, the right side wall 11 will be mainly described, and the description of the left side wall 11 will be omitted.

  The side wall 11 includes an outer plate portion 11A, a lower plate edge portion 11B, and an inner plate portion 11C. The outer plate portion 11A, the lower plate edge portion 11B, and the inner plate portion 11C are provided in this order in a state of being connected from one to the other in the step direction.

  The outer plate portion 11A is formed in a substantially trapezoidal shape in which one end portion (upper end portion) in the step direction is inclined. The outer plate portion 11A occupies most of the side wall 11, and constitutes the outer surface of the packaging box 1 in an assembled state (see FIG. 2). One end portion in the step direction of the outer plate portion 11A is inclined in one step (upward) in the step direction from the front wall 12 toward one side (rear) in the flow direction. The inclination angle of one end in the step direction of the outer plate portion 11A is set to about 18 to 20 degrees with respect to a horizontal line parallel to the flow direction, for example. At one end in the step direction of the outer plate portion 11A, an inner flap 17 is provided in a state of being connected via a ruled line L1. The ruled line L1 is a general-purpose ruled line formed by crushing a corrugated cardboard sheet linearly in the thickness direction from the back liner 2C side.

  The inner plate portion 11C is provided in a state of being connected to the other end portion (lower end portion) in the step direction of the outer plate portion 11A via two return lines L2. A lower plate edge portion 11B is formed between the two folding lines L2. Note that the folding line L2 is a general-purpose ruled line similar to the ruled line L1 described above.

  The lower plate edge portion 11B is formed in a substantially rectangular shape elongated in the flow direction, and the outer plate portion 11A and the inner plate portion 11C are made continuous. The dimension in the step direction of the lower plate edge portion 11B is set slightly longer than the thickness of the cardboard sheet. The inner plate portion 11C is formed in a substantially trapezoidal shape with the other end in the step direction inclined. The longest dimension in the step direction of the inner plate portion 11C is shorter than the longest dimension in the step direction of the outer plate portion 11A (for example, about 1/4).

  The other end portion in the step direction of the inner plate portion 11C is inclined from the front wall 12 toward one side (rear) in the flow direction and the other in the step direction. The inclination angle of the other end in the step direction of the inner plate portion 11C is set to about 18 to 20 degrees with respect to a horizontal line parallel to the flow direction, for example. A support convex portion 20 and a fitting projection 21 are formed at the other end in the step direction of the inner plate portion 11C. The support convex part 20 is formed on one side (substantially the rear half) from the approximate center in the flow direction of the inner plate part 11C. The support convex part 20 protrudes from the other end part in the step direction of the inner plate part 11C to the other. For this reason, the defect | deletion part 22 dented in the step direction one side relatively is formed in the other (substantially front half) rather than the flow direction approximate center of the inner plate part 11C. The fitting projection 21 is formed at a substantially central portion in the flow direction of the support convex portion 20. The fitting protrusion 21 slightly protrudes from the other end in the step direction of the support protrusion 20 to the other.

  The front wall 12 is disposed so as to be sandwiched between the pair of outer plate portions 11A. The front wall 12 is provided in a state of being connected to a pair of outer plate portions 11A via a ruled line L1. The front wall 12 is formed in a substantially rectangular shape. The dimension in the step direction of the front wall 12 is shorter than the dimension in the step direction of the outer plate part 11A, and the dimension in the flow direction of the front wall 12 is set longer than the dimension in the flow direction of the outer plate part 11A. One end portion (upper end portion) in the step direction of the front wall 12 is aligned with one inner corner portion in the step direction of the pair of outer plate portions 11A. For this reason, the step direction other end part (lower end part) of the front wall 12 is provided in the position which shifted | deviated to the step direction one side (upward) rather than the step direction other end part (folding line L2) of each outer-plate part 11A. Yes.

  An extraction hole 23 and a pair of contact end portions 24 are formed at the other end portion (lower end portion) in the step direction of the front wall 12. The take-out hole 23 is cut out from the other end (lower end) in the step direction toward one (upward) in the center of the front wall 12 in the flow direction (left-right direction). The extraction hole 23 is formed by connecting a substantially semicircular circular opening 23B to the top of a substantially triangular triangular opening 23A. At the other end in the step direction of the front wall 12, a pair of oblique sides 23 </ b> C are formed by the triangular openings 23 </ b> A that incline in the step direction one side (upward) from both sides in the flow direction. The pair of contact end portions 24 is the other end in the step direction of the front wall 12 and is formed on both sides in the flow direction of the extraction hole 23. The pair of contact end portions 24 extend substantially horizontally from the lower ends of the pair of oblique sides 23C toward the outer side in the left-right direction.

  The top wall 15 is provided in a state of being connected to one end (upper end) in the step direction of the front wall 12 via a ruled line L1. The top wall 15 is formed in a substantially rectangular shape. The dimension in the flow direction of the top wall 15 is substantially the same as the dimension in the flow direction of the front wall 12, and the dimension in the step direction of the top wall 15 is substantially the same as the length of the ruled line L 1 at one end in the step direction of the side wall 11. At one end in the step direction of the top wall 15, an engagement piece 15 </ b> A is provided in a state of being connected via a ruled line L <b> 1. The dimension (protrusion dimension) in the step direction of the engagement piece 15 </ b> A is set to be shorter than the dimension in the step direction of the top wall 15. A cut line L3 is formed substantially in parallel with the ruled line L1 at the center of the engagement piece 15A in the flow direction. The cut line L3 is formed by penetrating the blade in the thickness direction of the cardboard sheet.

  The rear wall 13 is provided in a state of being connected to the left outer plate portion 11A via a ruled line L1. The rear wall 13 is formed in a substantially rectangular shape having substantially the same size as the front wall 12. That is, the dimension in the step direction of the rear wall 13 is shorter than the dimension in the step direction of the outer plate part 11A, and the dimension in the flow direction of the rear wall 13 is set longer than the dimension in the flow direction of the outer plate part 11A. One end (upper end) in the step direction of the rear wall 13 is aligned with one corner in the step direction of the outer plate portion 11A. For this reason, the other end in the step direction (lower end) of the rear wall 13 is provided at a position shifted in one step in the step direction from the other end in the step direction (folding line L2) of the outer plate portion 11A. Further, the rear wall 13 is provided at a position further shifted in one step direction than the front wall 12.

  The rear wall 13 is formed with an opening 13A that is cut out in a substantially semicircular shape from one end in the step direction to the other. The opening 13A is formed at the center of the rear wall 13 in the flow direction (left-right direction). At the other end in the flow direction of the rear wall 13, a passage piece 14 is provided in a state of being connected via a ruled line L <b> 1.

  The bottom wall 16 is provided in a state of being connected to the other end (lower end) in the step direction of the rear wall 13 via a ruled line L1. The bottom wall 16 is formed in a substantially rectangular shape. The dimension in the step direction of the bottom wall 16 is shorter than the dimension in the step direction of the rear wall 13, and the dimension in the flow direction of the bottom wall 16 is set slightly shorter than the dimension in the flow direction of the rear wall 13. The other end portion in the step direction of the bottom wall 16 is aligned with the other corner portion in the step direction of the inner plate portion 11C. For this reason, the length in the step direction of the rear wall 13 and the bottom wall 16 is set to be substantially the same as the length (longest dimension) of the side wall 11 in the step direction.

  Four contact protrusions 25 protruding outward are formed at both ends in the flow direction (left-right direction) of the bottom wall 16. The four contact protrusions 25 are formed on the rear wall 13 side from the center of the bottom wall 16 in the step direction. Specifically, a pair of left and right contact protrusions 25 is formed at a position adjacent to the rear wall 13, and the remaining pair of left and right contact protrusions 25 is formed at a position spaced apart from the other in the stepwise direction. Therefore, a fitting recess 26 that is relatively recessed in the flow direction is formed between the two contact protrusions 25 that are separated in the step direction.

  In addition, a substantially rectangular bottom hole 27 is opened at the center in the flow direction of the bottom wall 16 and on the other side (front end side) of the center in the step direction of the bottom wall 16. One side of the bottom hole 27 on the tip side is curved so as to protrude toward the tip.

[Assembly of packaging box]
In the blank 2 described above, the right side wall 11 and the rear wall 13 are bent along the ruled line L1, and the passage piece 14 is bonded to the inner surface of the right side wall 11. Thereby, the packaging box 1 folded flat is formed. The packaging box 1 is delivered in a folded state to a manufacturer of the contents M, a store where the contents M are sold, and the like.

  Next, the assembly process of the folded packaging box 1 is demonstrated with reference to FIG.1, FIG.2, FIG.4 thru | or FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. 5 is a cross-sectional view taken along the line VV in FIG. FIG. 6 is a perspective view showing the packaging box 1 containing the contents M. FIG.

  A user (operator) forms the peripheral wall 10 by bending the pair of side walls 11, the front wall 12, and the rear wall 13 along a ruled line L1 extending in the step direction. The peripheral wall 10 is formed in a rectangular tube shape having an upper surface opening 10U on the upper surface and a lower surface opening 10D on the lower surface (see FIGS. 1 and 2). Subsequently, the user bends the bottom wall 16 forward along the ruled line L1. Then, the upper surface (back liner 2C) of the bottom wall 16 comes into contact with the pair of contact end portions 24 of the front wall 12 (see FIG. 1).

  In this state, the pair of side walls 11 are opposed to each other across the bottom wall 16 from the left-right direction (see FIGS. 1 and 2). The pair of outer plate portions 11 </ b> A are provided in a state extending below the bottom wall 16. The rear wall 13 is provided in a state of being connected to the rear end portions (one end portion in the extending direction) of the pair of side walls 11 (see FIG. 2). The front wall 12 faces the rear wall 13 and is provided in a state of being connected to the front ends (the other ends in the extending direction) of the pair of side walls 11 (see FIG. 1). Further, since the rear wall 13 is offset upward with respect to the front wall 12, the bottom wall 16 is inclined downward from the rear toward the front. The inclination angle of the bottom wall 16 is about 18 to 20 degrees with respect to the horizontal line, similarly to the inclination angle of the upper end portion of the outer plate portion 11A.

  Next, as shown in FIGS. 4 and 5, the user bends the pair of lower plate edge portions 11B and the pair of inner plate portions 11C inward along the two folding lines L2. The lower plate edge portion 11B is bent at a substantially right angle with respect to the outer plate portion 11A, and the inner plate portion 11C is bent at a substantially right angle with respect to the lower plate edge portion 11B. The inner plate portion 11C moves so as to overlap the inner surface of the outer plate portion 11A while bringing the fitting protrusion 21 into contact with the lower surface of the bottom wall 16 (the front liner 2B). When the fitting projection 21 is fitted into the fitting recess 26, the support projection 20 of the inner plate portion 11C comes into contact with the contact projection 25 (see FIG. 3) of the bottom wall 16.

  In this state, the inner plate portion 11C is provided in a state where it is folded inward at the lower end portion of the outer plate portion 11A. Further, the inner plate portion 11C supports the bottom wall 16 in a forward inclined posture by bringing the upper end portion thereof into contact with the lower surface of the bottom wall 16 (the front liner 2B). Specifically, the inner plate portion 11 </ b> C (supporting convex portion 20) supports the rear side of the bottom wall 16. More specifically, the support convex portion 20 supports the bottom wall 16 behind (substantially the rear half of the side wall 11) behind the substantially center of the side wall 11 when viewed from the side (see FIG. 5). . The lower part of the outer plate part 11A (below the bottom wall 13) and the inner plate part 11C serve as legs of the peripheral wall 10 and separate the bottom wall 13 upward from the installation surface GL.

  Further, as shown in FIG. 5, the bottom wall 16 extends from the lower end portion (one lower end portion of the peripheral wall 10) toward the front side (the other end) of the rear wall 13 so as to block the lower surface opening 10 </ b> D of the peripheral wall 10. Provided in the state. Further, the bottom wall 16 is provided in a state extending forward from the front wall 12 (the other outer surface of the peripheral wall 10). That is, the bottom wall 16 is provided in a cantilever shape in which the rear end is fixed to the rear wall 13 and the front end is free. The length from the front wall 12 to the front end (free end) of the bottom wall 16 is set to about 1/3 to 1/2 of the length in the front-rear direction of the peripheral wall 10 (side wall 11). The rear half of the bottom hole 27 is located inside the peripheral wall 10, and the front half of the bottom hole 27 is exposed to the outside (front) of the peripheral wall 10 (see FIG. 1).

  Next, as shown in FIGS. 5 and 6, the user puts a plurality of contents M into the peripheral wall 10 from the upper surface opening 10 </ b> U. The plurality of contents M are accommodated in the peripheral wall 10 in a state of being stacked one above the other. A part of the contents M accommodated in the peripheral wall 10 is exposed from the extraction hole 23. After the contents M are accommodated, the user bends the pair of inner flaps 17 along the ruled line L1, and bends the top wall 15 and the engagement piece 15A inward along the ruled line L1. Then, the user closes the upper surface opening 10U with the top wall 15 while inserting the engagement piece 15A into the peripheral wall 10 (see FIG. 2). As with the bottom wall 16, the top wall 15 is also inclined downward from the rear to the front, and the inclination angle is about 18 to 20 degrees with respect to the horizontal line.

  Thus, the assembly work of the packaging box 1 is completed. The packaging box 1 can be easily assembled without using an adhesive or an adhesive tape. The packaging box 1 is arranged in a standing posture on the installation surface GL with the pair of lower plate edge portions 11B in contact with the installation surface GL. Further, the bottom wall 16 is provided in a state in contact with or close to the pair of contact end portions 24 (the other lower end portion of the peripheral wall 10). The state in which the bottom wall 16 is close to the contact end portion 24 refers to a state in which a gap (smaller) than the thickness of the content M is formed between the bottom wall 16 and the contact end portion 24. . That is, the bottom wall 16 is in a state of facing the contact end portion 24 with a slight gap that restricts the passage of the contents M.

[Action of packaging box]
Next, the operation of the packaging box 1 will be described with reference to FIGS. FIG. 7 is a perspective view showing the packaging box 1 with a gap 30 opened. FIG. 8 is a perspective view showing the process of pulling out the contents M of the packaging box 1. 9 is a cross-sectional view taken along the line IX-IX in FIG.

  As described above, the bottom wall 16 before being bent downward is a flat plate having a forward inclined posture, and is in contact with or close to the pair of contact end portions 24 (see FIG. 5). As shown in FIG. 7, the bottom wall 16 of the packaging box 1 is bent downward so that the content 30 is taken out between the pair of contact end portions 24 (the lower end portion of the front surface of the peripheral wall 10). Is supposed to form.

  For example, the user inserts his / her index finger into the bottom hole 27 from above, and grips the lowermost content M arranged inside the take-out hole 23 with the index finger and thumb. In addition, the user pushes down the front side of the bottom wall 16 with a finger (hand) holding the contents M. Then, the front side of the bottom wall 16 bends downward with the front end portions of the pair of support convex portions 20 as fulcrums F (see FIG. 9). As a result, the bottom wall 16 is separated downward from the pair of contact end portions 24, and a gap 30 is formed between the bottom wall 16 and the pair of contact end portions 24. Since the bottom wall 16 is formed to be slightly narrower in the left-right direction than the front wall 12 and the like, the bottom wall 16 can be bent smoothly without interfering with the side walls 11. Moreover, since the defect | deletion part 22 lowered | lowered one step rather than the support convex part 20 is formed in the front side of each inner-plate part 11C (refer FIG. 9), the bottom wall 16 bent downward is each inner-plate part 11C. Interference can be suppressed.

  Subsequently, as shown in FIGS. 8 and 9, the user pulls the picked contents M forward along the upper surface of the bottom wall 16. Then, the content M is pulled out from the inner side of the peripheral wall 10 through the gap 30. At this time, the contents M are pulled out so as to slide down on the bottom wall 16 taking the forward tilting posture.

  When the contents M are completely pulled out of the peripheral wall 10 and the user's finger (hand) is separated from the bottom wall 16, the bottom wall 16 is lifted (returned to its original) by its own elastic force (restoring force). As a result, the bottom wall 16 contacts or approaches the pair of contact end portions 24, and the gap 30 is closed (narrowed) (see FIGS. 5 and 6). The contents M accommodated in the peripheral wall 10 are taken out by the above procedure. When the user releases his / her hand from the bottom wall 16 with the contents M pulled out halfway, the contents M are held in a state of being sandwiched between the bottom wall 16 and the contact end portions 24. In the above description, the contents M are taken out one by one. However, the present invention is not limited to this, and two or more contents M are taken out at the same time depending on the thickness of the contents M and the size of the gap 30. May be.

  In the packaging box 1 which concerns on this embodiment demonstrated above, it was set as the structure bent so that the front side of the bottom wall 16 may leave | separate below from the lower end part of the surrounding wall 10 (front wall 12). According to this configuration, for example, the gap 30 can be formed between the peripheral wall 10 and the bottom wall 16 by a simple operation in which the user pushes down the front side of the bottom wall 16 with a finger. Thereby, the content M accommodated in the peripheral wall 10 can be easily taken out (drawn out) through the gap 30. Further, when the user releases his / her finger from the bottom wall 16 (releases pressing down), the bottom wall 16 is automatically lifted by its own elastic force (restoring force). Thereby, since the clearance gap 30 is closed automatically (it becomes narrow), the jumping-out of the content M accommodated in the surrounding wall 10 can be suppressed. That is, the content M can be appropriately held inside the peripheral wall 10.

  Moreover, according to the packaging box 1 which concerns on this embodiment, since the bottom wall 16 protrudes ahead (the other side) rather than the surrounding wall 10 (front wall 12), a user pushes down the part which the bottom wall 16 protruded easily. The operation can be performed. Further, a bottom hole 27 was opened in the bottom wall 16 from the inner side to the outer side of the peripheral wall 10. According to this configuration, since the user can put his / her finger into the bottom hole 27, the user can easily pick the content M of the lowest layer in contact with the bottom wall 16. Thereby, for example, only the content M of the lowest layer can be easily taken out.

  Moreover, according to the packaging box 1 which concerns on this embodiment, since the bottom wall 16 is formed in the downward slope toward the front from back, the content M pulled out from the clearance gap 30 follows the inclination of the bottom wall 16. Can be slid down. Thereby, the contents M can be smoothly taken out from the peripheral wall 10.

  Moreover, in the packaging box 1 which concerns on this embodiment, since a pair of side wall 11 (outer plate part 11A) is extended below the bottom wall 16, and is earth | grounding to the installation surface GL, the bottom wall 16 is from the installation surface GL. Was also located above. According to this configuration, it is possible to prevent the depressed bottom wall 16 from interfering with the installation surface GL. Thereby, since the bottom wall 16 can be pushed down appropriately, the clearance gap 30 required for taking out the content M can be ensured. Moreover, since it is located above installation surface GL, it can suppress that the user's hand which pulled out the content M collides with installation surface GL. Thereby, the content M can be taken out efficiently.

  Moreover, in the packaging box 1 which concerns on this embodiment, it was set as the structure which 11 C of inner-plate parts used as the fulcrum F of bending support the rear side of the bottom wall 16. As shown in FIG. According to this configuration, the distance from the fulcrum F to the front side of the bottom wall 16 serving as the action point can be increased as compared with the case where the inner plate portion 11C supports the front side of the bottom wall 16. As a result, the user can easily bend the bottom wall 16 downward with a small force. In addition, by increasing the distance between the fulcrum F and the action point, it is possible to sufficiently ensure the bending width (movement distance due to pressing down) on the front side of the bottom wall 16. Thereby, since the big clearance gap 30 is formed, the content M can be taken out easily.

  Further, according to the packaging box 1 according to the present embodiment, the user can put the finger into the take-out hole 23 while pushing down the bottom wall 16 and can firmly grasp the content M, and easily remove the content M through the gap 30. It can be taken out.

  In addition, in the packaging box 1 which concerns on this embodiment, although the surrounding wall 10 was formed in square tube shape, this invention is not limited to this. For example, the peripheral wall may be formed in a cylindrical shape having a polygonal cross section other than a quadrangle, or may be formed in a cylindrical shape having a circular or elliptical cross section. Further, the shape of the bottom wall 16 may be formed in a polygonal shape other than a quadrangle in accordance with the cross-sectional shape of the peripheral wall 10, or may be formed in a circular shape or an elliptical shape.

Further, in the packaging box 1 according to the present embodiment, the front wall 12 has a substantially triangular (substantially mountain-shaped) extraction hole 23 and the bottom wall 16 has a substantially rectangular bottom hole 27. The present invention is not limited to this. The shape and size of the extraction hole 23 and the bottom hole 27 can be changed as appropriate.
Further, the extraction hole 23 and the bottom hole 27 may be omitted.

  In the packaging box 1 according to this embodiment, the length from the front wall 12 to the front end (free end) of the bottom wall 16 is 1/3 to 1/2 of the length in the front-rear direction of the peripheral wall 10 (sidewall 11). However, the present invention is not limited to this. For example, the bottom wall 16 may protrude slightly forward (about several millimeters) from the front wall 12 or may extend more than ½ of the length in the front-rear direction of the peripheral wall 10. Although illustration is omitted, the bottom wall may not extend forward from the front wall 12. For example, even if the bottom wall is formed in the same shape and size as the lower surface opening 10D, and the front end of the bottom wall is provided at substantially the same position (on the same surface) as the front wall 12 (the front surface thereof). Good. In this case, the bottom hole 27 may be omitted.

  In the packaging box 1 according to the present embodiment, in the assembled state, the inclination angle of the top wall 15 (the upper end portion of the outer plate portion 11A) and the inclination angle of the bottom wall 16 (the upper end portion of the inner plate portion 11C) are respectively However, the present invention is not limited to this. For example, the angle can be set in the range of 0 to 50 degrees with respect to the horizontal line. Therefore, the bottom wall 16 may be provided substantially parallel (substantially horizontal) to the installation surface GL. In addition, the bottom wall 16 extends from the rear to the front, but is not limited thereto, and may be provided to extend from the front to the rear, or may be provided to extend toward the side. Good.

  Moreover, in the packaging box 1 which concerns on this embodiment, although a pair of side wall 11 was extended below the bottom wall 16, and the bottom wall 16 was arrange | positioned above the installation surface GL, this invention is limited to this. Not. For example, although illustration is omitted, when the user uses the packaging box by hand, the inner plate portion 11C and the like are omitted, and the bottom wall 16 is fixed to the lower ends of the pair of side walls (outer plate portion 11A). Also good. Even in this case, the bottom wall 16 bends downward to form a gap 30 between the bottom wall 16 and the lower end of the front wall 12.

  Further, in the packaging box 1 according to the present embodiment, the pair of inner plate portions 11C (the pair of support convex portions 20) support the rear side of the bottom wall 16, and the bending support point F of the bottom wall 16 is the side wall 11. Although it is set at approximately the center in the front-back direction, the present invention is not limited to this. For example, the position at which the pair of support protrusions 20 support the bottom wall 16 may be changed, and the fulcrum F of the deflection of the bottom wall 16 may be set forward or rearward of the center of the side wall 11 in the front-rear direction.

  Moreover, although the thin substantially rectangular plate-shaped content M was accommodated in the packaging box 1 (circumferential wall 10) which concerns on this embodiment, this invention is not limited to this. For example, the content of various shapes, such as a substantially rectangular parallelepiped shape (box shape), a substantially cylindrical shape, or a substantially spherical shape, may be accommodated in the packaging box 1 (the peripheral wall 10).

  Moreover, although the packaging box 1 which concerns on this embodiment was formed with the cardboard made from paper, it is not restricted to this, For example, you may form with the board made from a cardboard, resin, etc.

  In addition, description of the said embodiment shows the one aspect | mode in the packaging box which concerns on this invention, Comprising: The technical scope of this invention is not limited to the said embodiment.
