Description

The present invention relates to a foldable packaging box for packaging an article.

Since this type of packaging box is generally used for business purposes, in particular, it is required to be easy to use, and in addition to packaging, for example, individual packaging boxes containing bags are contained in the packaging box. Many packaging boxes are stacked and transported or stored in the vertical direction, and there is a demand for suppression of paralysis and prevention of damage to packaging boxes and packages due to collapse of cargo. there were.
Recently, there has been a demand for a structure that can be easily dismantled for disposal and recycling after use.

Therefore, an invention described in Japanese Patent Laid-Open No. 9-207940 (Patent Document 1) has been known for the purpose of solving the above problems.
In the invention of Patent Document 1, an inverted trapezoidal side plate is provided on both sides of a single bottom plate via a fold, and the trapezoid is substantially symmetrical with the side plate on the outside of the side plate on both sides. And the 1st side surface board provided with the latching protrusion on both sides is provided.

  A pair of locking holes is provided on the crease line between the bottom plate and the side plate, and the pair of inverted U-shaped locking projections is formed by cutting into the folds of the side plate and the first side inner plate. It is provided corresponding to the hole.

  On the other hand, it can be folded in two at the four corners of the front and rear side plates and the inverted trapezoidal side plate, and there are four pieces of box-like box-shaped pieces with two auxiliary locking projections and locking holes on the front and rear side plates. It will be.

Further, a second side inner plate is provided on the outside of the front and rear side plates via a crease, and the locking projection of the first side inner plate on the crease line between the second side inner plate and the box-making piece. A packaging board having a notch corresponding to the above is provided.
The height of the inverted trapezoidal side plate and the front and rear side plates are the same, and the height of the first side inner plate and the second side inner plate is lower than the height of the side plate.

  Then, the packaging board box piece is folded in two through a fold, and the box making piece is folded to the side plate side at the inclined fold of the inverted trapezoid side plate, The first side inner plate is bent inward through a fold at the boundary with the inverted trapezoidal side plate, and a pair of inverted U-shaped locking projections are ejected from the cut, and the box is made. The auxiliary locking projection provided on the piece is inserted into the notch provided with the inverted U-shaped locking projection, and the triple U-shaped locking projection and the two auxiliary locking projections The locking projections on both sides provided on both sides of the first side surface inner plate are cut by cutting the second side surface inner plate by being locked by the projection and further bending the second side surface inner plate inward. A packaging box in which the first side inner plate, the box-making piece, and the second side inner plate are bent inwardly, inserted in the notch. It was.

  Therefore, when this packaging box is stacked in the vertical direction, the triple locking protrusion of the packaging paper device located below can be inserted into the locking hole between the bottom piece located above and the inverted trapezoidal side plate, It is possible to prevent wrapping paper containers stacked in the up-and-down direction from being reluctant, and to be evaluated in terms of being less likely to be bent or torn due to the triple locking protrusions.

  However, the background art has a simple structure, such as providing a first side inner plate, a box piece, and a second side inner plate, and providing two pieces of auxiliary locking protrusions on the outer periphery of the box piece. In this type of product that is required to be made, the structure is complicated, and in addition, it is essential to bend the first side inner plate, the box-making piece, and the second side inner plate inward. In addition to production, there was a problem in assembly during use.

  By inserting the triple protrusion into the locking hole, the packaging paper device stacked in the vertical direction is designed not to move around, but it simply stops when the locking protrusion is inserted into the locking hole. Since the regulation of the face plate is left unattended, there is a risk that the triple projections may come out of the locking holes due to a relatively slight impact during truck transportation or store display, and the stacked packaging boxes may fall down.

In addition to the background art described above, Patent Document 1 describes a configuration in which double locking projections are inserted into the locking holes as another embodiment, but the configuration is not changed, and the above-described problem Is not a solution.
JP-A-9-207940

  The problem to be solved is the lack of usability, complicated assembly and disassembly, and the fact that the side plate is not regulated, so that the protrusion is locked by a relatively slight impact. For example, the stacked packaging boxes may fall out of the hole.

In order to achieve the above object, the problem solving means of the first invention of the present invention is:

Since the problem-solving means of the first invention of the present invention has the above-described configuration, it is excellent in usability and less complicated in assembly and disassembly.
When stacking, the upper packaging box follows the height of the insertion piece by inserting the insertion hole of the upper packaging box into the insertion piece of the lower packaging box. Since it descends to the opening side of the packaging box, it is possible to suppress the back and forth and lateral movement of the upper and lower packaging boxes.
Since the height of the second side plate and the fourth side plate is higher than the height of the first side plate and the third side plate, the insertion hole of the upper packaging box is inserted into the insertion piece of the lower packaging box. Thus, the outer side surfaces of the second side plate and the fourth side plate on the bottom side of the packaging box located above are held by the inner side surfaces of the second side plate and the fourth side plate located below. In combination with the control of the insertion hole and the insertion piece, there is no reluctance in the direction between the second side plate and the fourth side plate of the packaging box located above.
In addition, since the first side plate and the third side plate are inverted trapezoidal, the interval between the second side plate and the fourth side plate on the opening side of the packaging box is the first side plate and the third side plate. Therefore, it is easy to insert the packaging box between the second side plate and the fourth side plate during stacking.
Further, since the second side plate and the fourth side plate are trapezoidal, the length of the bottom side of the packaging box is formed longer than the length of the opening side, so that the upper side when the packaging boxes are stacked. It is easy to place the box on the lower box, and there is no risk of shifting in the front-rear direction in combination with the control of the insertion hole and the insertion piece (see FIGS. 4, 5, 10, and 11). ).

  Since the problem-solving means of the second invention of the present invention has the above-described configuration, in addition to the effects exhibited by the problem-solving means of the first invention, the first side plate and the fourth side plate are locked. There is an advantage that the first side plate and the fourth side plate can be easily combined without being glued or taped by bending the pieces toward each other and fitting the respective notches to each other.

Since the problem-solving means of the third invention of the present invention has the above-described configuration, in addition to the effects exhibited by the problem-solving means of the first or second invention, the bottom of the packaging box body is the first bottom plate. And the set of the third bottom plate and the set of the second and fourth bottom plates,
Since the inner and outer double bottoms can be provided, the bottom can be strengthened.
In addition, the first and third partition plates and the second and fourth partition plates are folded inward to accommodate the cross-shaped individual packaging box 4. Individual cells can be easily obtained.
Further, by folding the second partition plate and the fourth partition plate on the first bottom plate 24 and the third bottom plate 28, the four cells are reduced to two, but the cells in the case of four are used. Since it is easy to obtain a cell having a size twice as large as that of the above, the packaging box can be used twice (see FIGS. 8 and 9).

  A pair of inverted trapezoidal first side plates and third side plates are arranged to face each other for the purpose of preventing a plurality of packaging boxes from falling over when stacked, and a pair of trapezoidal second side plates and fourth side plates Are arranged opposite to each other, and the second side plate and the fourth side plate are made higher in height than the first side plate and the third side plate.

Embodiment 1 of the present invention will be described below with reference to FIG.
The basic configuration of the present invention is referred to as an A-type cardboard box in the industry. In the unfolded state, the first side plate 12 and the second side plate are arranged on one side with a common lateral fold line 32 as a boundary. 14, four side plates of a third side plate 16 and a fourth side plate 18 are provided (see FIG. 1).
In Example 1, together with Example 2 to be described later, the material used is corrugated cardboard, but this does not preclude the selection of other materials such as kraft paper.

  These four side plates 12, 14, 16, and 18 will be described in detail later, but their outlines are characteristic, and each of the four side plates is a series of adjacent vertical folds 20a, 20b, and 20c. Inseparably connected (see FIG. 1).

  An inverted trapezoidal first side plate 12, a trapezoidal second side plate 14, an inverted trapezoidal third side plate 16 common to the first side plate 12, and a first side plate 12, with a common lateral fold line 32 as a boundary. A trapezoidal fourth side plate 18 common to the two side plates 14 is provided in an inseparable manner via a first fold line 20a, a second fold line 20b, and a third fold line 20c that are adjacent to each other and are inclined in the vertical direction. (See FIG. 1).

As described above, the contours of the first side plate 12 and the third side plate 16 are inverted trapezoids, while the contours of the second side plate 14 and the fourth side plate 18 are trapezoidal. The first fold line 20a, the second fold line 20b, and the third fold line 20c are governed by the outline of each side plate.
As shown in FIG. 1, when viewed from the second side plate 14, the first fold 20 a at the boundary between the first side plate 12 and the second side plate 14 extends laterally from the outer edge of the second side plate 14. It is provided so as to be inclined outward at a certain angle over the crease 32 (see FIG. 1).
On the other hand, when viewed from the first side plate 12, the first side plate 12 is provided so as to be inclined at a constant angle.

When viewed from the second side plate 14, the second fold 20b at the boundary between the second side plate 14 and the third side plate 16 is governed by its outline, and the second side plate is symmetrical to the inclination direction of the first fold 20a. 14 is provided so as to be inclined outward at a constant angle from the outer edge 14 to the lateral crease 32 (see FIG. 1).
On the other hand, when viewed from the third side plate 16, the third side plate 16 is provided so as to be inclined at a constant angle.

The third fold 20c at the boundary between the third side plate 16 and the fourth side plate 18 is transverse to the outer edge of the fourth side plate 18 when viewed from the fourth side plate 18, similarly to the first fold 20a. The fold line 32 is provided so as to be inclined outward at a certain angle (see FIG. 1).
On the other hand, when viewed from the third side plate 16, the third side plate 16 is provided so as to be inclined at a constant angle.

This inclination angle differs depending on the thickness of the second side plate 14 and the fourth side plate 18 that are to be erected on both sides in preparation for the case where the packaging box mount 10a is assembled as a packaging box 10A and stacked vertically. However, it is also governed by the height of the packaging box 10A.
Regarding this inclination angle, practical examples of mathematical expressions will be shown below.

(Equation 1)
(A−b) ÷ l = X

Referring to FIG. 5, the height of the first side plate 12 and the third side plate 16 is “l”, the width on the opening side is “a” (the distance between the vertical line and the contour line), and the width on the bottom side Is “b” (equal to the thickness of the first side plate 12 or the third side plate 16), the inclination angle can be calculated as (ab) / l = X as described above.
Incidentally, if “l” is 100 mm, “a” is 6 mm, and “b” is 3 mm, the tilt angle X can be calculated as 3/100.

Of the four side plates, the height α from the lateral fold line 32 of the second side plate 14 and the fourth side plate 18 facing each other during assembly to the outer edge on the side parallel to the lateral fold line 32 is the first. The first side plate 12 and the third side plate 16 are provided with a height higher than the height β extending from the lateral fold line 32 to the lateral fold line 32 and the outer edge on the parallel side.
The height described above sets the height of the box 10A when used as the packaging box 10A (see FIGS. 2 to 5).

The lateral folds 32 and the parallel outer edges of the first side plate 12 and the third side plate 16 do not refer to the outer edges of the insertion piece 36 to be described later, but exist on both sides thereof. It is an edge.
It has been explained that the above-described height α of the second side plate 14 and the fourth side plate 18 is higher than the above-described height β of the first side plate 12 and the third side plate 16, but it protrudes high. For convenience of explanation, these portions are referred to as projecting portions 14a and 18a.

  Intended for stability when the packaging box 10A is stacked, elongated insertion pieces 36, 36 are respectively provided on the outer edges of the first side plate 12 and the third side plate 16 parallel to the lateral fold line 32, Insertion holes 38 and 38 corresponding to the long and narrow insertion pieces 36 and 36 are provided at the boundary between the first side plate 12 and the third side plate 16 and the respective bottom plates 24 and 28.

A semicircular cutout 40 is provided at the center of these insertion holes 38 on the first side plate 12 side and the third side plate 16 side.
This notch 40 is intended for the case where a plurality of packaging boxes 10A are stacked one above the other and for the dismantling of the packaging box 10A, and is intended to allow a fingertip to be inserted for ease of operation of the packaging box 10A. is there.

On the other hand, a first bottom plate 24, a second bottom plate 26, a third bottom plate 28, and a fourth bottom plate 30 are provided on the other side with the fold line 32 as a boundary.
The four bottom plates 24, 26, 28, 30 are separated from each other by a fold line 32 in the lateral direction, and the first side plate 12 has the first bottom plate 24 and the second side plate 14 has the second bottom plate. 26, a third bottom plate 28 is connected to the third side plate 16, and a fourth bottom plate 30 is connected to the fourth side plate 18 so as to be foldable.

These four bottom plates 24, 26, 28, and 30 are laid out in the following because they have characteristics in their respective forms in order to eliminate the need for gluing and tape fastening to constitute the bottom portion.
The first bottom plate 24 has a generally half-cut shape, and an outer edge on one locking piece 22a side described below is inclined inward from the locking piece 22a side to the second bottom plate 26 side. Thus, an inclined portion 24a is formed.
On the other hand, the second bottom plate 26 side of the first bottom plate 24 is formed vertically, and an elongated protrusion 24b is formed on the outer edge parallel to the lateral fold line 32.

  The second bottom plate 26 has an inverted triangular shape as a whole, and an elongated interference portion 26 a is formed on the outer edge on the side parallel to the lateral fold line 32.

  The third bottom plate 28 is provided symmetrically with the first bottom plate 24 described above, is formed with an inclined portion 28a and an elongated protruding portion 28b, and the second bottom plate 26 side is formed vertically.

The fourth bottom plate 30 has a rectangular shape as a whole, and a cutout 30a is provided on the third bottom plate 28 side and the other locking piece 22b side on the outer side.
The interference part 26a of the second bottom plate 26 is formed on the outer edge parallel to the lateral fold line 32.
An elongated notch 30b is formed as an interfered part corresponding to the above.
Elongated protrusions 30c are formed on both sides of the elongated notch 30b in parallel with the lateral fold line 32, respectively.

The notch 30a described above is provided on the side of the elongated notch 30b provided as the interfered portion. However, when the insertion piece 36 is inserted into the insertion hole 38, the insertion hole 38 is formed. It is designed so as not to be blocked, and is formed so as to surround both sides of the fourth bottom plate 30.

  When the four side plates are assembled in a square shape, the first side plate 12 and the fourth side plate 18 adjacent to each other can be easily combined without being glued or taped. The outer side of the fourth side plate 18 is preferably provided with locking pieces 22a and 22b, respectively.

A pair of locking pieces 22a and 22b are provided symmetrically on the outer sides of the first side plate 12 and the fourth side plate 18, respectively.
At the boundary between one locking piece 22a and the first side plate 12, along the contour of one locking piece 22a side of the first side plate 12, from the outside of the first side plate 12 to the lateral fold 32 A locking piece fold 20d inclined inward toward the middle of the locking piece 22a is provided, and at the extension end of the locking piece fold 20d, a slope common to the inclination of the locking piece fold 20d is provided. A cut 34a is provided.
The boundary between the fourth side plate 18 and the other locking piece 22b is symmetrical with the locking piece fold 20d and the notch 34a provided at the boundary between the one locking piece 22a and the first side plate 12. Stop piece folds 20e and cuts 34b are provided.

Therefore, a process of assembling the packaging box 10A by combining the packaging box mount 10a according to the first embodiment will be described.
(1) The first side plate 12, the second side plate 2, the second side plate 12, 20 b, 20 c formed between the four side plates 12, 14, 16, 18 of the packaging box mount 10 a. The side plate 14, the third side plate 16, and the fourth side plate 18 are folded in a rectangular shape facing inward.

(2) By folding the packaging box mount 10a into a square shape, the locking pieces 22a provided on the first side plate 12 and the locking pieces 22b provided on the fourth side plate 18 are kept symmetrical with each other, The two locking pieces 22a and 22b are bent so that the cross-section is in an L shape inward with the respective folds 20d and 20e as boundaries, while the folds 20d and 20e are The respective notches 34a and 34b formed on the extension are inserted into each other, and both the locking pieces 34a and 34b are attached.
Thus, the packaging box mount 10a is configured as a rectangular shape with its top and bottom open.

  Next, as apparent with reference to FIG. 2, the bottom plate made of four pieces is bent inward, and by incorporating these four bottom plates, tape is not attached to the bottom plate or glued. The bottom of the packaging box 10A can be formed.

Since the process of incorporating these four bottom plates is as known, the details will be omitted, but (3) the fourth bottom plate 30 is directed inward at right angles through the lateral folds 32. Bend it.
Thus, the cutout 30b of the fourth bottom plate 30 faces the central portion of the packaging box 10A.

(4) Next, the first bottom plate 24 and the third bottom plate 28 located on both sides are directed inward through the lateral fold lines 32 and outside the fourth bottom plate 30 bent first. Bend at a right angle.
Thus, the protruding portion 24b of the first bottom plate 24 and the protruding portion 28b of the third bottom plate 28 face each other, and the inclined portions 24a and 28a of both cover the protruding portion 30c side of the fourth bottom plate 30. Become.

(5) Next, the second bottom plate 26 is directed inward through the lateral fold line 32, bent at a right angle, and positioned outside the first bottom plate 24 and the third bottom plate 28. At this time, The first bottom plate 24 and the third bottom plate 28 are pressed inward, and the fourth bottom plate 30 is also pressed.
By further pressing the second bottom plate 26, the fourth bottom plate 30 is forcibly controlled by the pressing force of 26a of the second bottom plate 26 and tilted inward.
Therefore, by further pressing the second bottom plate 26, the interference part 26a of the second bottom plate 26 enters the inner side of the notch 30b of the fourth bottom plate 30 and enters the inner side thereof, and the second inclined side is inclined inward. The four bottom plates 30 are restored in the horizontal direction.
Thus, when these four bottom plates interfere with each other, the bottom of the packaging box 10 can be easily formed without gluing or tape fastening.

  This can be easily carried out in case of dismantling after use, restoring to a flat mount 10a, and transporting.

Next, the case where the packaging boxes 10A described above are stacked in three stages will be described with reference to FIG. 3, FIG. 4, and FIG.
(6) Stack the second-stage packaging box 10n-2 and the third-stage packaging box 10n-3 in the same direction on the first-stage packaging box 10n-1. Is the case.
Second-stage packaging box in which the insertion pieces 36, 36 provided on the first side plate 12 and the third side plate 16 of the first-stage packaging box 10 n-1 located at the lower position are located at the upper position. 10n-2 insertion holes 38, 38 are inserted.

(7) At this time, since the first side plate 12 and the third side plate 16 are provided in an inverted trapezoidal shape as described above, in other words, with respect to the length of the bottom plate side of the packaging box 10A. The length of the opening side of the packaging box 10A is large.
Therefore, although the second side plate 14 and the fourth side plate 18 connected to the first side plate 12 and the third side plate 16 are trapezoidal, respectively, the inverted side trapezoidal first side plate 12 and third side plate are provided. 16, the distance between the two on the bottom plate side 14 and 18 coincides with the length on the bottom plate side of each of the first side plate 12 and the third side plate 16 and is short on the opening side of the packaging box 10. The length is large.

  4 and 5, the second-stage packaging box 10n-2 is placed on the first-stage packaging box 10n-1, and the third-stage packaging box 10n. -3 are stacked, the second side plate 14 and the fourth side plate 18 of the packaging box positioned at the upper level are the same as the second side plate 14 and the fourth side plate 18 of the packaging box positioned at the lower level. It is supported between the protrusions 14a.

  In this case, since the “a” (see FIG. 5) corresponds to the thickness of the second side plate 14 and the fourth side plate 18, the second stage located at the upper level. The second side plate 14 and the second side plate 18 of the eye packaging box 10n-2 have the second side plate and the second side plate 14n-1 of the first stage packaging box 10n-1 positioned on the lower side of the bottom plate side. The upper second packaging box 10n-2 has a lower first stage without any gap between the side plate 14 and the fourth side plate 18 and the inner side surface of the packaging box on the opening side. It will be supported by the eye packaging box 10n-1, and there is no risk of bothering when both boxes are stacked.

  When the third-stage packaging box 10n-3 is stacked on the second-stage packaging box 10n-2, the second-stage packaging box 10n-1 is placed on the first-stage packaging box 10n-1. Since it is common with the case where the packaging boxes 10n-2 for eyes are stacked, the above description is used.

Although this Example 2 has the difference in the presence or absence of a partition plate compared with Example 1, other structures are not fundamentally different.
Therefore, about the common structure, description of the said Example 1 is used and a different structure is mentioned.
In the drawings, common parts are represented in common unless otherwise noted for convenience of explanation.

The packaging board 50a of the second embodiment is similar to the mounting board 10a of the first embodiment described above, on the one side of the fold 32 in the lateral direction of the packaging board 50a. The side plate 14, the third side plate 16, and the fourth side plate 18 are continuously connected in series through the first fold line 20a, the second fold line 20b, and the third fold line 20c in the vertical direction.

Of these four side plates, in the second side plate 14 and the fourth side plate 18, a part of the lateral fold 32 and a part of the outer edge on the parallel side are notched toward the lateral fold 32 side. A pair of notches 14b and 18b are formed, respectively.
These notches 14b and 18b are intended to allow a finger to be inserted to take out, for example, the individual packaging box of the bag when using the packaging box 50A.
