Description

The present invention relates to a packaging box.

2. Description of the Related Art There is known an A-type packaging box that contains and seals contents such as beverage cans and PET bottles.

For example, the setup case (packing box) described in Patent Document 1 is formed in a rectangular parallelepiped shape by closing the upper and lower edges of a quadrangular tubular body formed of a wide side panel and a narrow side panel with large and small flaps. ing. An unsealing tape for taking out the beverage container (contents) is attached around the quadrangular tubular body. Opening guide cuts are intermittently formed on the ridges of the adjacent side panels. The narrow side panel is provided with a substantially V-shaped cut for cutting the opening tape, and a pair of cut portions are symmetrically provided with the opening tape sandwiched therebetween. The pair of cutting portions are formed in a substantially C-shape with the distance between them widening toward the ridge, and are connected to the opening guide cut.

JP 2002-166927 A

The above-mentioned set-up case (hereinafter, also simply referred to as “case”) is placed in a standing posture like a well-known wrap round type case, and the narrow side panel can be opened. In detail, the operator turns the toe surface of the case upward, grasps the substantially D-shaped notch, and draws the unsealing tape to the ridgeline. Then, the worker cuts the divided side panel along the notch for the opening guide. In this way, by opening the toe surface of the case, it becomes possible to quickly put the horizontally stacked beverage containers in a vending machine or a refrigerator.

By the way, when all of the beverage containers in the case cannot be put into the vending machine or the like, the operator carries the case in a standing posture on a trolley in a laid posture. The reason for this is that the case in the standing posture is unstable, and it prevents falling during transportation. However, when the case with the toe surface opened is laid sideways, there is a problem that the beverage container falls over in the case or jumps out of the case.

In order to solve the above problems, the present invention provides a packaging box that suppresses the movement of contents in a state where a side plate or an end plate is opened and placed horizontally.

In order to achieve the above-mentioned object, the present invention provides a pair of side plates and a pair of end plates alternately connected through a first ridge line, and a flap is provided for each side plate and each end plate. A packing box continuously provided via a second ridge line orthogonal to the first ridge line, which is for unsealing extending in a direction along the second ridge line by the pair of side surface plates and the pair of end face plates. A tear portion, a pair of dividing lines formed in the pair of side plates or the pair of end face plates so as to cut the tear portion in the vicinity of the first ridge, each dividing line, and each first ridge. A pair of first ruled lines obliquely formed between one end of the first ridge line and a pair of second ruled lines obliquely formed between each of the dividing lines and the other end of each first ridge line, With the space between the pair of dividing lines opened, one of the side surface plate and the end surface plate is provided so as to be able to contact the contents by being folded inward at the second ridge line, and the side surface plate and the end surface plate. The other of the end face plates is provided so that either the side face plate or the end face plate can be fixed by being folded inward along the first ruled line and the second ruled line.

In this case, it is preferable to further include a pair of cutting edge lines formed so as to be able to cut the side surface plate and the end surface plate on one side or the other side of each of the first ridge lines with the tear portion interposed therebetween.

In this case, each of the side plate, the end plate and the flap is made of corrugated cardboard in which a front liner and a back liner are attached to both sides of the middle shin, and the tearing portion cuts the back liner in parallel. Each of the dividing lines is formed by cutting the cardboard in the thickness direction, and each of the first ruled lines and each of the second ruled lines is 45 degrees with respect to the first ridgeline. It is preferable that the cutting edge lines are formed by linearly crushing in the thickness direction from the back liner side at an inclination angle of, and the cutting edge lines are formed by intermittently cutting the corrugated board in the thickness direction.

ADVANTAGE OF THE INVENTION According to this invention, movement of the content in a packing box can be suppressed in the state where the packing box which opened the side plate or the end plate was set horizontally.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The packing box 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a packing box 1. FIG. 2 is a plan view showing the blank 2 of the packaging box 1.

As shown in FIG. 1, the packaging box 1 is an A-type box that is closed by closing the upper surface and the lower surface of a rectangular cylindrical peripheral wall 3. Inside the packing box 1, for example, a plastic bottle P (contents) for beverage is stored (see FIG. 3 ). Note that, for convenience of description, terms indicating directions and positions (for example, terms including top (top), bottom (bottom), vertical, horizontal, side, and end) will be used below, but these terms are used in the present invention. Does not limit the technical scope of the.

As shown in FIG. 2, the packaging box 1 is formed by assembling a blank 2 obtained by punching out a piece of paper corrugated board with a paper machine punching device. The corrugated board is a well-known corrugated board in which a front liner 2b and a back liner 2c (see FIG. 3) are attached to both front and back surfaces of a corrugated center lining 2a. 2 shows the front liner 2b side (outer surface side of the packaging box 1). In the following description, a direction parallel to the corrugated paper core 2a will be referred to as a "step direction", and a direction orthogonal to the step direction will be referred to as a "flow direction".

The blank 2 is formed by alternately connecting a pair of side plates 10 and a pair of end plates 11 in the flow direction. The face plates 10 and 11 are each formed in a rectangular plate shape having the same width in the step direction. Each end face plate 11 is formed to have a smaller dimension (length) in the flow direction than each side face plate 10. A passage piece 12 is continuously provided at the end of the side plate 10 in the flow direction, which is one end of the blank 2.

An outer flap 13 is continuously provided at both ends of each side plate 10 in the step direction, and an inner flap 14 is continuously provided at both ends of each end plate 11 in the step direction. Each outer flap 13 and each inner flap 14 are formed in a rectangular plate shape having the same length in the step direction. The dimension of each outer flap 13 in the flow direction is formed to be substantially the same as the dimension of the side plate 10 in the flow direction. The dimension of each inner flap 14 in the flow direction is formed to be substantially the same as the dimension of the end plate 11 in the flow direction.

A fold line 15 crushed linearly in the thickness direction from the back liner 2c side is formed at a boundary portion between each face plate 10, 11, the passage piece 12, and each flap 13, 14 (one-dot chain line in FIG. 2). reference). Each folding line 15 is formed to bend each face plate 10, 11, the passage piece 12, and each flap 13, 14.

A tear strip 16 for opening that extends over the entire area in the flow direction is formed on the passage piece 12, the pair of side surface plates 10, and the pair of end surface plates 11. A tear band 16 as an example of a tear portion is formed substantially at the center in the step direction of the passage piece 12, each side plate 10, and each end plate 11. The tear band 16 is composed of two liner cuts 16a obtained by cutting the back liner 2c in parallel. Corresponding to the center of the pair of end plates 11 in the flow direction, corrugated cardboard is cut in the thickness direction to form knobs 17A and 17B, respectively.

Next, the assembly process of the packaging box 1 will be described with reference to FIGS. 1 and 2.

First, the face plates 10 and 11 and the passage piece 12 are bent along a folding curve 15 and the passage piece 12 is attached to the end face plate 11 located at the other end of the blank 2. Then, the pair of side surface plates 10 and the pair of end surface plates 11 are alternately arranged through the vertical ridge lines 20 (first ridge lines) to form the rectangular cylindrical peripheral wall 3 (see FIG. 1 ). The position of each vertical ridge line 20 corresponds to the position of the folding curve 15 extending in the step direction.

Then, each inner flap 14 located at the lower part of the peripheral wall 3 is bent at a folding line 15, and then each outer flap 13 is bent at a folding line 15 and bonded to each inner flap 14. Each outer flap 13 is continuously provided to the side plate 10 via a horizontal ridge line 21 (second ridge line) orthogonal to the vertical ridge line 20. Each inner flap 14 is continuously provided to the end face plate 11 via a lateral ridge line 21. Thus, the lower portion of the peripheral wall 3 is closed, and the bottom surface of the packaging box 1 is formed. The position of each lateral ridge 21 corresponds to the position of the folding curve 15 extending in the flow direction.

Next, for example, a plurality (for example, 6 in the long side direction×4 in the short side direction=24 bottles) of PET bottles P (see FIG. 3 and the like) are placed on the bottom surface of the packaging box 1 (each flap 13, 14). Place on. Subsequently, the inner flaps 14 and the outer flaps 13 located on the upper portion of the peripheral wall 3 are bent along a folding line 15, and the outer flaps 13 are attached to the inner flaps 14. In this way, the upper portion of the peripheral wall 3 is closed and the top surface of the packaging box 1 is formed (see FIG. 1). By the above, the packing box 1 is sealed. The front ends of the pair of inner flaps 14 facing each other are separated from each other, and the front ends of the pair of outer flaps 13 facing each other are butted at substantially the center (see FIG. 1 ).

When opening the packing box 1, the operator pulls the pair of gripped gripping portions 17A (17B) so as to separate them from each other. Since the tear strips 16 are provided on the entire circumference of the peripheral wall 3, the side plates 10 and the end plates 11 are cut along the liner cuts 16a. Thereby, the packaging box 1 can be divided (opened) into upper and lower parts.

In addition, as an example, when the PET bottle P is put into the vending machine, the packaging box 1 in which a part of the one end plate 11 is opened is displaced to the upright position (the end plate 11 is directed upward). Then, the PET bottle P may be taken out from the opening. In this way, by opening the end face plate 11, the worker can quickly insert the plastic bottle P into the vending machine. When the PET bottle P remains in the packing box 1, the worker carries the packing box 1 on a trolley in a posture in which the packing box 1 is laid sideways. At this time, there is a risk that the plastic bottle P may fall inside the packaging box 1 or may jump out of the packaging box 1 through the opening. Therefore, the packaging box 1 according to the present embodiment is provided with a configuration that suppresses the movement of the plastic bottle P even when the end face plate 11 is opened and placed horizontally.

Hereinafter, a configuration (folding structure) for suppressing the movement of the PET bottle P in the packaging box 1 will be described.

As shown in FIGS. 1 and 2, the folding structure of the packaging box 1 is configured to be capable of holding a state in which the vertically divided end face plates 11 are folded inside (inside the packaging box 1). The folding structure of the packaging box 1 includes a pair of dividing lines 30, a pair of first ruled lines 31, a pair of second ruled lines 32, and a pair of cutting edge lines 33.

The pair of dividing lines 30 are formed at positions facing each other on the pair of side surface plates 10. Each of the pair of dividing lines 30 is formed on the side plate 10 so as to cut the tear band 16 in the vicinity of the vertical ridge line 20 on one side in the long side direction of the packaging box 1. Each of the dividing lines 30 is formed by cutting the corrugated board in the thickness direction and extending in the vertical direction. Each dividing line 30 is extended so as to intersect the two liner cuts 16a at a right angle.

The pair of first ruled lines 31 and the pair of second ruled lines 32 are formed at positions facing each other on the pair of side surface plates 10. The pair of first ruled lines 31 are formed obliquely between each dividing line 30 and the upper end (one end) of each vertical ridge line 20 (see FIG. 1 ). The pair of second ruled lines 32 are formed obliquely between each dividing line 30 and the lower end (other end) of each vertical ridge line 20 (see FIG. 1 ). The first ruled lines 31 and the second ruled lines 32 are formed so as to spread in the vertical direction from the dividing line 30 toward the vertical ridge line 20. Each first ruled line 31 and each second ruled line 32 is formed at an inclination angle of 45 degrees with respect to the vertical ridge line 20. The first ruled lines 31 and the second ruled lines 32 are formed by linearly crushing in the thickness direction from the back liner 2c side. Both ends of each first ruled line 31 and both ends of each second ruled line 32 are not connected to the dividing line 30 or the vertical ridge line 20, respectively.

The pair of cutting edge lines 33 are formed along the vertical ridge lines 20 on both sides of the end plate 11. The pair of cutting edge lines 33 are formed so as to be able to cut the side surface plate 10 and the end surface plate 11 on the upper side (one side) of each vertical ridge line 20 with the tear band 16 interposed therebetween. Each cutting edge line 33 is formed by intermittently cutting a corrugated board in the thickness direction. In detail, each cutting edge line 33 is formed by cutting a partial cutting line 33a at two locations separated in the vertical direction. The strength of the packaging box 1 can be ensured by cutting the two partial cutting lines 33a at intervals.

Next, the operation of the folding structure of the packaging box 1 will be described with reference to FIG. FIG. 3 is a perspective view showing the end plate 11 of the packaging box 1.

The operator opens a part of the end face plate 11 sandwiched between the pair of cutting edge lines 33. Specifically, the worker pulls the gripped pair of grip portions 17A (see FIG. 1) to both outer sides in the short side direction, and cuts (removes) the tear band 16 between the pair of dividing lines 30. Then, the end plate 11 and a part of each side plate 10 are vertically divided. For convenience of description, the upper end face plate 11 will be referred to as an upper end face plate 11U, and the lower end face plate 11 will be referred to as a lower end face plate 11D with the tear band 16 as a center.

Subsequently, the operator flips the upper end plate 11U upward along the lateral ridgeline 21. At this time, the upper end plate 11U is cut from the pair of side plates 10 along each cutting edge line 33, and is bent outward along the lateral ridge line 21. Thus, by cutting the upper end face plate 11U along the vertical ridge line 20, the upper end face plate 11U can be easily opened. Then, the worker displaces the packaging box 1 to the upright posture and sets the opening 34 as the upper surface. As a result, the PET bottle P can be quickly taken out from the packing box 1.

Next, with reference to FIGS. 4 and 5, a case will be described in which the packing box 1 is transported in a state where, for example, the first row (four) of PET bottles P lined up on the end face plate 11 side is taken out. FIG. 4 is a perspective view showing a state in which the ends of the end plate 11 and the side plate 10 of the packing box 1 are folded. FIG. 5 is a sectional view taken along line VV of FIG.

First, the worker bends the lower end face plate 11D inward along the lateral ridgeline 21. Then, the end portions of the pair of side surface plates 10 connected to the lower end face plate 11D are folded inward along the second ruled lines 32, respectively. At this time, the lower end face plate 11D and the pair of side face plates 10 are folded inward while switching the folding direction of the pair of vertical ridges 20. That is, the pair of vertical ridges 20 are respectively changed from the mountain fold state to the valley fold state and overlap the inside of the horizontal ridge line 21. In this state, the end portions of the pair of side surface plates 10 are each folded into a substantially right-angled isosceles triangle having the second ruled line 32 as the hypotenuse and press the lower end face plate 11D. This can prevent the end of each side plate 10 and the lower end plate 11D from returning to the outside. The tip of the folded lower end face plate 11D is arranged at a position where it is pressed against the lower portion of the second-row PET bottle P (see FIG. 5 ).

Subsequently, the worker folds the upper end face plate 11U inward along the lateral ridge line 21. After that, the worker folds the end portions of the pair of side surface plates 10 connected to the upper end surface plate 11U inward along the first ruled line 31. In this state, the end portions of the pair of side surface plates 10 are each folded into a substantially right-angled isosceles triangle shape having the first ruled line 31 as the hypotenuse, and the upper end surface plate 11U is pressed. Further, the restoring force that the upper end plate 11U tries to return to the outside acts on each folded side plate 10, so that each side plate 10 is held in a substantially triangular shape. That is, the end of each side plate 10 and the upper end plate 11U exert a force on each other to hold the folded state. This can prevent the end of each side plate 10 and the upper end plate 11U from returning to the outside.

The pair of dividing lines 30, the pair of first ruled lines 31, and the pair of second ruled lines 32 are geometrically set so that the ends of the folded side plate 10 are substantially isosceles right triangles. There is. In the above description, the upper end face plate 11U is folded inward after the lower end face plate 11D is folded inward, but the invention is not limited to this. The lower end face plate 11D is folded after the upper end face plate 11U is folded. You may fold it in.

When the PET bottle P is taken out again, the side plates 10 on the upper side, which are folded into a substantially triangular shape, are returned to the original state, and the upper end face plate 11U is folded back on the outside. Thereby, the operator can take out the PET bottle P remaining in the packaging box 1.

According to the packaging box 1 according to the present embodiment described above, the end face plate 11 is folded inward along the lateral ridgeline 21 in a state where the tear band 16 between the pair of dividing lines 30 is cut (opened). The side plate 10 is provided so as to be able to come into contact with the PET bottle P, and the end face plate 11 can be fixed by being folded inward at the first ruled line 31 and the second ruled line 32. For example, the packaging box 1 with the PET bottle P left inside is displaced to a posture in which the opening 34 is oriented horizontally during transportation. The lower part of the plastic bottle P is pressed against the tip of the folded lower end face plate 11D. Even if the PET bottle P falls down toward the opening 34, the upper portion (cap portion) of the PET bottle P contacts the tip of the folded upper end face plate 11U. Therefore, the plastic bottle P is restricted from moving toward the opening 34 in the packaging box 1. As a result, it is possible to prevent the PET bottle P from falling down inside the packaging box 1 or jumping out of the packaging box 1.

Note that, in the above description, as an example, the folding structure of the packaging box 1 in the state in which the first row (four bottles) of PET bottles P are taken out has the operation and effect, but the present invention is not limited to this. This folding structure works effectively even when two or more rows (eight) of PET bottles P are taken out. Although illustration is omitted, for example, a space in which the remaining PET bottles P can be moved is formed inside the packing box 1 in which two rows (8 bottles) of PET bottles P are taken out. For this reason, the remaining plastic bottle P may slide or fall when the packaging box 1 is transported. Even in this case, since the upper end face plate 11U, the lower end face plate 11D, and the end parts of the respective side face plates 10 are folded inward to narrow the opening 34, they come into contact with the sliding or falling PET bottle P. .. This prevents the PET bottle P from sliding and falling, and can prevent the PET bottle P from jumping out of the packaging box 1.

Further, according to the packaging box 1 according to the present embodiment, the upper end face plate 11U, the lower end face plate 11D, and the end portions of the respective side face plates 10 are folded inward to form the opening 34, and thus the opening is formed. Corrugated cardboard is overlapped around the portion 34. As a result, the strength around the opening 34 can be improved.

In addition, in the packaging box 1 according to the present embodiment, the dividing line 30, the first ruled line 31, the second ruled line 32, and the cutting edge line 33 are formed on one side in the long side direction of the packaging box 1 (FIG. 1 and FIG. 2), the present invention is not limited to this. Although not shown, these lines 30 to 33 may be formed on one side of the packaging box 1 in the short side direction. That is, even if a pair of dividing lines 30, a pair of first ruled lines 31 and a pair of second ruled lines 32 are formed on the end face plate 11 and a pair of cutting edge lines 33 are formed on the vertical ridge lines 20 on both sides of the side face plate 10. Good. In this case, in a state where the tear strip 16 between the pair of dividing lines 30 is cut out (opened), the side surface plate 10 is folded inward along the lateral ridge line 21 and provided so as to be able to contact the PET bottle P, and the end face plate. 11 is provided so that the side plate 10 can be fixed by being folded inward at the first ruled line 31 and the second ruled line 32. In addition, although not shown, two sets of a pair of dividing lines 30, a pair of first ruled lines 31, a pair of second ruled lines 32, and a pair of cutting edge lines 33 are provided, and these two sets of lines 30 to 33 are provided. May be formed on both sides in the long side direction (or both sides in the short side direction) of the packaging box 1.

In addition, in the packaging box 1 which concerns on this embodiment, although a pair of cutting edge line 33 was formed in the upper side of the vertical ridge line 20, this invention is not limited to this. It may be formed on the lower side (other side) of each vertical ridge 20 with the tear band 16 interposed therebetween. Besides, the pair of cutting edge lines 33 may be omitted. In this case, the upper end plate 11U (or the lower end plate 11D) can be cut from the side plate 10 along the vertical ridge line 20.

In addition, in the packaging box 1 according to the present embodiment, the tear strip 16 is composed of two liner cuts 16a, but the present invention is not limited to this. For example, instead of the two liner cuts 16a, a resin cut tape (for example, width 5 mm, thickness 50 μm) may be attached to the back liner 2c (not shown). It is preferable that the cut tape is provided on the entire circumference of the peripheral wall 3 so as to pass through substantially the vertical center of each of the knobs 17A and 17B. The cut tape is cut by the grip portions 17A, 17B and the dividing lines 30. Alternatively, instead of the two liner cuts 16a, one zipper (one-side zipper) or two zippers (both zippers) may be provided on the entire circumference of the peripheral wall 3 (both not shown). Each zipper is a well-known one formed by arranging a plurality of bent cutting lines in a line. Further, instead of the two liner cuts 16a, one or two sewing blade lines in which cutting lines are linearly arranged at predetermined intervals may be provided on the entire circumference of the peripheral wall 3 (not shown). No).

Note that the packaging box 1 according to the present embodiment is formed of paper corrugated cardboard as an example, but the present invention is not limited to this. For example, a cardboard made of resin may be used instead of the cardboard made of paper, or a single cardboard or resin sheet may be used. Further, the packaging box 1 according to the present embodiment stores the PET bottle P as the content, but the present invention is not limited to this, and for example, a can, a bottle, or the like may be stored.

In addition, the description of the above embodiment shows one mode of the packaging box according to the present invention, and the technical scope of the present invention is not limited to the above embodiment. The constituent elements in the above embodiment can be replaced or combined with existing constituent elements as appropriate, and the description of the above embodiment does not limit the contents of the invention described in the claims. ..
