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 the assembled state (see FIG. 2). One end in the step direction of the outer plate portion 11A is inclined in one step direction (upward) from the front wall 12 toward one side (rear) in the flow direction. The inclination angle of one end of the outer plate portion 11A in the step direction is set to, for example, about 18 to 20 degrees with respect to the horizon parallel to the flow direction. An inner flap 17 is provided at one end of the outer plate portion 11A in the step direction 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) of the outer plate portion 11A in the step direction via two folding lines L2. A lower plate edge portion 11B is formed between the two folding lines L2. The folding line L2 is a general-purpose ruled line similar to the ruled line L1 described above.

The support convex portion 20 projects from the other end of the inner plate portion 11C in the step direction to the other. Therefore, a defect portion 22 recessed in one side in the step direction is formed on the other side (substantially the front half) of the inner plate portion 11C from the substantially center in the flow direction. The fitting protrusion 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 of the support convex portion 20 in the step direction to the other.

The front wall 12 is arranged 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 of the front wall 12 in the step direction is shorter than the dimension of the outer plate portion 11A in the step direction, and the dimension of the front wall 12 in the flow direction is set longer than the dimension of the outer plate portion 11A in the flow direction. One end portion (upper end portion) of the front wall 12 in the step direction is aligned with the inner corner portion of one of the pair of outer plate portions 11A in the step direction. Therefore, the other end portion (lower end portion) of the front wall 12 in the step direction is provided at a position deviated from the other end portion (folding line L2) of each outer plate portion 11A in the step direction in the step direction. There is.

The take-out hole 23 is cut out from the other end (lower end) in the step direction toward one side (upper side) in the central portion of the front wall 12 in the flow direction (left-right direction). The take-out 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 of the front wall 12 in the step direction, a pair of hypotenuses 23C that are inclined in one step direction (upward) from both sides in the flow direction toward the center are formed by the triangular opening 23A. The pair of contact end portions 24 are the other end portions of the front wall 12 in the step direction, and are formed on both sides of the take-out hole 23 in the flow direction. The pair of contact end portions 24 extend substantially horizontally from the lower end portions of the pair of hypotenuse portions 23C toward the outside in the left-right direction.

The top wall 15 is provided in a state of being connected to one end (upper end) of the front wall 12 in the step direction via a ruled line L1. The top wall 15 is formed in a substantially rectangular shape. The dimensions of the top wall 15 in the flow direction are substantially the same as the dimensions of the front wall 12 in the flow direction, and the dimensions of the top wall 15 in the step direction are substantially the same as the length of the ruled line L1 at one end of the side wall 11 in the step direction. One end of the top wall 15 in the step direction is provided with engaging pieces 15A connected to each other via a ruled line L1. The dimension (protruding dimension) of the engaging piece 15A in the step direction is set shorter than the dimension of the top wall 15 in the step direction. A cut line L3 is formed in the central portion of the engaging piece 15A in the flow direction substantially parallel to the ruled line L1. The cut line L3 is formed by penetrating the cutting tool in the thickness direction of the corrugated cardboard sheet.

The rear wall 13 is provided in a state of being connected to the outer plate portion 11A on the left side 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 of the rear wall 13 in the step direction is shorter than the dimension of the outer plate portion 11A in the step direction, and the dimension of the rear wall 13 in the flow direction is set longer than the dimension of the outer plate portion 11A in the flow direction. One end (upper end) of the rear wall 13 in the step direction is aligned with one corner of the outer plate portion 11A in the step direction. Therefore, the other end portion (lower end portion) of the rear wall 13 in the step direction is provided at a position shifted to one side in the step direction from the other end portion (folding line L2) of the outer plate portion 11A in the step direction. Further, the rear wall 13 is provided at a position further deviated from the front wall 12 in one step direction.

The rear wall 13 is formed with an opening 13A cut out in a substantially semicircular shape from one end in the step direction toward 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 of the rear wall 13 in the flow direction, a joint piece 14 is provided in a state of being connected to each other via a ruled line L1.

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

Four abutting protrusions 25 protruding outward are formed at both ends of the bottom wall 16 in the flow direction (left-right direction). The four contact protrusions 25 are formed on the rear wall 13 side of the bottom wall 16 in the step direction. Specifically, a pair of left and right contact protrusions 25 are formed at positions adjacent to the rear wall 13, and the remaining pair of left and right contact protrusions 25 are formed at positions separated from them in the step 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.

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

[Assembly of packaging box]
In the blank 2 described above, the right side wall 11 and the rear wall 13 are bent at the ruled line L1, and the joint piece 14 is adhered to the inner surface of the right side wall 11. As a result, the flatly folded packaging box 1 is formed. The packaging box 1 is delivered in a folded state to a manufacturer of the content M, a store of the content M, or the like.

Next, the assembly process of the folded packaging box 1 will be described with reference to FIGS. 1, 2, 4 to 6. FIG. 4 is a sectional view taken along line IV-IV of FIG. FIG. 5 is a sectional view taken along line VV of FIG. FIG. 6 is a perspective view showing a packaging box 1 containing the contents M.

The user (operator) bends the pair of side walls 11, the front wall 12, and the rear wall 13 along the ruled line L1 extending in the step direction to form the peripheral wall 10. The peripheral wall 10 is formed in a square tubular 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 face each other with the bottom wall 16 interposed therebetween from the left-right direction (see FIGS. 1 and 2). The pair of outer plate portions 11A are provided in a state of extending downward from the bottom wall 16. The rear wall 13 is provided in a state of being connected to the rear end portion (one end portion in the extension direction) of the pair of side walls 11 (see FIG. 2). The front wall 12 is provided in a state of facing the rear wall 13 and being connected to the front end portion (the other end portion 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 to the front. The inclination angle of the bottom wall 16 is about 18 to 20 degrees with respect to the horizon, 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 projection 21 into contact with the lower surface (front liner 2B) of the bottom wall 16. When the fitting protrusion 21 is fitted into the fitting recess 26, the support convex portion 20 of the inner plate portion 11C is in contact with the contact protrusion 25 (see FIG. 3) of the bottom wall 16.

In this state, the inner plate portion 11C is provided in a state of being 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 leaning posture by bringing its upper end portion into contact with the lower surface (front liner 2B) of the bottom wall 16. Specifically, the inner plate portion 11C (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 the side wall 11 substantially in the front-rear direction (approximately the rear half of the side wall 11) when viewed from the side (see FIG. 5). .. The lower portion of the outer plate portion 11A (below the bottom wall 13) and the inner plate portion 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 of the rear wall 13 (one lower end portion of the peripheral wall 10) toward the front (the other) so as to close the lower surface opening 10D of the peripheral wall 10. Provided in the state. Further, the bottom wall 16 is provided in a state of 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 the shape of a cantilever with the rear end fixed to the rear wall 13 and the front end 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 inserts a plurality of contents M into the peripheral wall 10 from the upper surface opening 10U. The plurality of contents M are housed in the peripheral wall 10 in a state of being stacked vertically. A part of the contents M housed in the peripheral wall 10 is exposed from the take-out hole 23. After accommodating the contents M, the user bends the pair of inner flaps 17 inward along the ruled line L1 and the top wall 15 and the engaging piece 15A inward along the ruled line L1. Then, the user inserts the engaging piece 15A into the peripheral wall 10 and closes the upper surface opening 10U with the top wall 15 (see FIG. 2). Like 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 horizon.

As described above, the assembly work of the packaging box 1 is completed. The packaging box 1 can be easily assembled without using an adhesive, an adhesive tape, or the like. The packaging box 1 is arranged in an upright posture on the installation surface GL with a pair of lower plate edge portions 11B in contact with the installation surface GL. Further, the bottom wall 16 is provided in a state of being in contact with or close to a 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 (narrower) than the thickness of the content M is formed between the bottom wall 16 and the contact end portion 24. .. That is, it refers to a state in which the bottom wall 16 faces the contact end portion 24 with a slight gap that restricts the passage of the content M.

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

As described above, the bottom wall 16 before bending downward is in the shape of a flat plate in a forward leaning 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 to form a gap 30 between the bottom wall 16 and the pair of contact end portions 24 (the lower end portion of the front surface of the peripheral wall 10) for taking out the contents M. Is designed to form.

For example, the user inserts the index finger into the bottom hole 27 from above, and picks the lowermost content M arranged inside the take-out hole 23 with the index finger and the thumb. Further, the user pushes down the front side of the bottom wall 16 with a finger (hand) that picks up the content 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, it can be smoothly bent without interfering with each side wall 11. Further, since a defective portion 22 that is one step lower than the support convex portion 20 is formed on the front side of each inner plate portion 11C (see FIG. 9), a bottom wall 16 that is bent downward is formed on each inner plate portion 11C. Interference can be suppressed.

Subsequently, as shown in FIGS. 8 and 9, the user pulls the picked contents M toward the front along the upper surface of the bottom wall 16. Then, the content M is pulled out from the inside to the outside of the peripheral wall 10 through the gap 30. At this time, the content M is pulled out so as to slide down on the bottom wall 16 which takes a forward leaning posture.

When the content M is completely pulled out from the peripheral wall 10 and the user's finger (hand) separates from the bottom wall 16, the bottom wall 16 is lifted (returned) by its own elastic force (restoring force). As a result, the bottom wall 16 comes into contact with or close to the pair of contact ends 24, and the gap 30 is closed (narrowed) (see FIGS. 5 and 6). By the above procedure, the contents M housed in the peripheral wall 10 are taken out. When the user releases the content M from the bottom wall 16 in a state where the content M is pulled out halfway, the content M is held in a state of being sandwiched between the bottom wall 16 and each contact end portion 24. Further, in the above description, the contents M are taken out one by one, but 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. You may.

In the packaging box 1 according to the present embodiment described above, the front side of the bottom wall 16 is bent so as to be separated downward from the lower end portion of the peripheral wall 10 (front wall 12). According to this configuration, for example, a 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. As a result, the contents M housed in the peripheral wall 10 can be easily taken out (pulled out) through the gap 30. Further, when the user releases the finger from the bottom wall 16 (releases the push-down), the bottom wall 16 is automatically lifted by its own elastic force (restoring force). As a result, the gap 30 is automatically closed (narrowed), so that the content M housed in the peripheral wall 10 can be prevented from popping out. That is, the content M can be appropriately held inside the peripheral wall 10.

Further, according to the packaging box 1 according to the present embodiment, since the bottom wall 16 protrudes forward (the other side) from the peripheral wall 10 (front wall 12), the user can easily push down the protruding portion of the bottom wall 16. You can perform operations. Further, the bottom wall 16 had a bottom hole 27 opened from the inside to the outside of the peripheral wall 10. According to this configuration, since the user can insert a finger into the bottom hole 27, the user can easily pick the contents M of the lowermost layer in contact with the bottom wall 16. Thereby, for example, only the contents M of the lowermost layer can be easily taken out.

Further, according to the packaging box 1 according to the present embodiment, since the bottom wall 16 is formed with a downward slope from the rear to the front, the contents M drawn out from the gap 30 are formed along the slope of the bottom wall 16. Can be slipped off. As a result, the content M can be smoothly taken out from the peripheral wall 10.

Further, in the packaging box 1 according to the present embodiment, since the pair of side walls 11 (outer plate portion 11A) extends downward from the bottom wall 16 and is in contact with the installation surface GL, the bottom wall 16 is in contact with the installation surface GL. Was also placed above. According to this configuration, it is possible to prevent the pushed-down bottom wall 16 from interfering with the installation surface GL. As a result, the bottom wall 16 can be appropriately pushed down, so that the gap 30 required for taking out the contents M can be secured. Further, since it is located above the installation surface GL, it is possible to prevent the hand of the user who pulled out the content M from colliding with the installation surface GL. As a result, the work of taking out the content M can be efficiently performed.

Further, in the packaging box 1 according to the present embodiment, the inner plate portion 11C serving as the fulcrum F of the deflection supports the rear side of the bottom wall 16. According to this configuration, the distance from the fulcrum F to the front side of the bottom wall 16 which is the point of action 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. Further, by increasing the distance between the fulcrum F and the point of action, it is possible to sufficiently secure the bending width (moving distance by pushing down) on the front side of the bottom wall 16. As a result, a large gap 30 is formed, so that the content M can be easily taken out.

Further, according to the packaging box 1 according to the present embodiment, the user can firmly pick up the content M by inserting a finger into the take-out hole 23 while pushing down the bottom wall 16, and can easily pick up the content M through the gap 30. Can be taken out.

In the packaging box 1 according to the present embodiment, the peripheral wall 10 is formed in a square tubular shape, but the present invention is not limited to this. For example, the peripheral wall may be formed in a tubular shape having a polygonal cross section other than a quadrangle, or may be formed in a tubular shape having a circular or elliptical cross section.

Further, in the packaging box 1 according to the present 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 (side wall 11). Although set to a degree, the present invention is not limited to this. For example, the bottom wall 16 may slightly protrude forward (about several millimeters) from the front wall 12, or may extend by 1/2 or more of the length of the peripheral wall 10 in the front-rear direction. Further, although not shown, the bottom wall may not extend forward from the front wall 12. For example, even if the bottom wall is formed to have substantially the same shape and size as the lower surface opening 10D, and the front end portion of the bottom wall is provided at substantially the same position (on the same surface) as the front wall 12 (front surface). Good. In this case, the bottom hole 27 may be omitted.

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

Further, in the packaging box 1 according to the present embodiment, the pair of side walls 11 extend below the bottom wall 16 and the bottom wall 16 is arranged above the installation surface GL, but the present invention is limited to this. Not done. For example, although not shown, the inner plate portion 11C and the like are omitted when the user uses the packaging box by hand, and the bottom wall 16 is fixed to the lower end portion of the pair of side walls (outer plate portion 11A). May be good. Even in this case, the bottom wall 16 bends downward to form a gap 30 with the lower end portion of the front wall 12.

Further, in the packaging box 1 according to the present embodiment, the pair of inner plate portions 11C (pair of supporting convex portions 20) support the rear side of the bottom wall 16, and the fulcrum F of the deflection of the bottom wall 16 is the side wall 11. Although it was set substantially in the center in the front-rear direction, the present invention is not limited to this. For example, the position where the pair of support convex portions 20 support the bottom wall 16 may be changed so that the fulcrum F of the deflection of the bottom wall 16 is set forward or backward of the center of the side wall 11 in the front-rear direction.

Further, the packaging box 1 (peripheral wall 10) according to the present embodiment contains a thin substantially rectangular plate-shaped content M, but the present invention is not limited to this. For example, contents having various shapes such as a substantially rectangular parallelepiped shape (box shape), a substantially cylindrical shape, and a substantially spherical shape may be housed in the packaging box 1 (peripheral wall 10).

Further, the packaging box 1 according to the present embodiment is formed of corrugated cardboard made of paper, but is not limited to this, and may be formed of, for example, thick paper or a plate made of resin.
