Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging box which is packaged in a substantially rectangular parallelepiped shape and accommodates an object to be packaged, and is packaged in an outer box.

[0002]

[Prior art]

 For example, as shown in FIG. 11, a maker of various recording media wraps a plurality of recording media (not shown) wrapped for each retail unit, and wraps them in a packaging box 51. Further, as shown in FIG. , 51... (10 as an example) are housed in the outer box 11 and shipped. In this case, the outer box 11 is a transport box for transporting the packaging boxes 51, 51,..., And is made of thick cardboard to protect the recording medium in the packaging box 51. On the other hand, at a retail store, first, the lids 11a, 11a,... Of the outer box 11 are opened to take out the packaging boxes 51, 51,..., And then the packaging box 51 is opened to display the recording medium. In this case, in order to prevent the packaging boxes 51, 51,... From rattling in the box during transportation, the packaging boxes 51, 51,. It is formed in such a size that no gap is formed between the box 51 and the outer box 11. For this reason, in a state where the packaging boxes 51, 51,... Are housed in the exterior box 11 in an orderly manner, a hand may be inserted between the packaging boxes 51, 51 or between the packaging box 51 and the exterior box 11. Therefore, it is very difficult to take out one packaging box 51 from the outer box 11 first. Therefore, in a retail store, for example, by holding the lids 11a, 11a of the outer box 11 in a hand and pulling them in opposite directions to break the space between the side plates 11b, 11c, etc., the outer box 11 is closed.・ I am taking out.

[0003]

[Problems to be solved by the invention]

 However, the conventional packaging method for accommodating a plurality of packaging boxes 51, 51,... In the outer box 11 has the following problems. That is, in the conventional packaging method, it is possible to take out the stored packaging boxes 51, 51,. However, the outer box 11 is formed of a durable material such as corrugated paper in order to protect the packaging box 51 (recording medium). Therefore, it is difficult for an elderly person or a weak person such as a woman to tear the outer box 11 by hand, so that the outer boxes 11 cannot be easily removed from the outer box 11. There is a point. In this case, a method of severing the outer box 11 using a blade is also conceivable. However, in this method, it is very difficult to tear only the outer box 11 without damaging the packaging box 51 and the recording medium therein, and in the worst case, an injury due to a mishandling of the blade may be caused. There is a problem.

[0004] On the other hand, Japanese Patent No. 3115541 discloses a perforated box (1, an outer box) provided with perforations (8a, 9a). According to this box, the contents can be taken out by breaking the perforated portion by hand without using a blade. However, no matter how perforated, it is still difficult for a weak person to tear the corrugated paper by hand. Conversely, if a weak person has perforations that are easily broken, the perforated parts may break during transport and be disassembled. As described above, it is actually difficult to solve the contradictory problem that the contents can be easily taken out while avoiding breakage during transportation with the box box disclosed in the publication.

[0005] Further, Japanese Utility Model Registration No. 25656599 discloses a packaging box provided with a hanging portion (14) that can protrude above the upper lid (12). According to this packaging box, even if a plurality of packaging boxes are neatly accommodated in the outer box and there is no gap for inserting a hand, one packaging box can be pulled up by grasping the hanging hand portion and pulling it up. It seems that it can be easily removed. However, since the hanging portion is used to hang the packaging box during display, it is folded so as to be flush with the rear plate (2) at the time of shipment. For this reason, there is a problem that it is very difficult to cause the hanging portion to protrude above the upper lid in a state where the hanging portion is properly housed in the outer box. In addition, when the hanging portion is raised, a hole having the same shape as the hanging portion is formed in the back plate, so that the strength of the back plate is reduced and the aesthetic appearance of the entire packaging box is impaired.

The present invention has been made in view of such a problem, and has as its main object to provide a packaging box which can be easily taken out of a state where it is housed in an outer box without lowering its strength. I do.

[0016]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the packaging box according to the present invention will be described with reference to the accompanying drawings.

A packaging box 1 shown in FIG. 1 is a box body for packaging a video tape cassette, an optical recording medium or the like (an example of a packaging object in the present invention), and includes a bottom plate 2 and side plates 3a to 3a. d, a top plate 4 and a grip flap 5 are provided to form a rectangular parallelepiped box. As shown in FIG. 2, the packaging box 1 is housed in an exterior box 11 together with a plurality of packaging boxes 1a, 1b, 1 (the packaging boxes 1a and 1b are the same as the packaging box 1). Is shipped to a retail store or the like, and is taken out of the outer box 11 at the retail store or the like, and is also used as a display case for an object to be packed. The outer box 11 that houses the packaging boxes 1, 1,... Is not particularly limited. For example, as an example, ten outer packaging boxes 1, 1,... With the side plate 3b facing upward are housed. It is made of corrugated paper as possible.

This packaging box 1 is made into a rectangular parallelepiped box by bending a blank B1 shown in FIG. 3 along a fold line. In addition, the blank B1 shown in the figure illustrates a surface that is inside the packaging box 1 in a box making state. In this case, the blank B1 is formed by cutting a single piece of ball paper into a predetermined shape and applying a fold line or a perforated line BL at a predetermined position to form the bottom plate 2, the side plates 3a to 3d, the top plate 4, and the holding plate. A flap 5 and the like are formed. The bottom plate 2 employs a so-called lock type structure, and is composed of four flaps of bottom plate flaps 2a to 2d as shown in FIG. The bottom plate flaps 2a to 2d constitute one plate surface (bottom plate 2) by being combined in a predetermined order at the time of box making. The side plates 3a to 3d constitute four side surfaces of the packaging box 1, and are connected in order in the order of the side plates 3b, 3a, 3c, and 3d via fold lines. In this case, the side plates 3a and 3d are formed in the same shape and are opposed to each other in a box making state, and the side plates 3b and 3c are formed in the same shape and are opposed to each other in a box making state. Further, closing flaps 7 for closing the gaps between the top plate 4 and the side plates 3b, 3c in a box-making state are respectively connected to the side plates 3b, 3c via fold lines. Further, a joining flap 6 for joining the side plate 3d to the side plate 3b and a top plate 4 are connected to the side plate 3d via fold lines, respectively.

The top plate 4 is formed in the same shape as the bottom plate 2 integrally formed by the bottom plate flaps 2a to 2d, and is arranged to face the bottom plate 2 in a box-making state. On the top plate 4, a flap for insertion 8 is provided on one side opposite to one side connected to the side plate 3d via a fold line, and is orthogonal to one side on which the flap 8 for insertion is formed. On one of the two sides, a gripping flap 5 is continuously provided via a perforation processing line BL. In this case, one side of the base end side (the bottom side in the present invention where the perforation processing line BL is formed and connected to the top plate 4) of the gripping flap 5 is connected to the front end side (the present invention). Is formed in a trapezoidal shape longer than (upper side in FIG. 3). The holding flap 5 has a flap length (the distance L1 shown in the figure) which is less than half the height of the side plates 3a to 3d (the distance L2 shown in the figure), and a joining flap. 6 is formed so as to be shorter than the flap length (distance L3). In this case, as an example, the flap length (distance L1) of the holding flap 5 is equal to the flap length (distance L3) of the joining flap 6, and is about １ ／ of the height (distance L2) of the side plates 3a to 3d. It is stipulated that

In this case, the joining flap 6 has its flap length specified to be a length necessary and sufficient for joining the side plates 3b and 3d. On the other hand, the grip flap 5 needs to have a flap length that can be gripped when the packaging box 1 is taken out of the outer box 11 as described later. In this case, the gripping flap 5 becomes easier to grip as the flap length is longer. However, when cutting the blank B1 from the cardboard, if the flap length of the gripping flap 5 is equal to or shorter than the flap length of the joining flap 6, the blank B1 is cut regardless of the presence or absence of the gripping flap 5. When the flap length of the gripping flap 5 is defined to be longer than the flap length of the joining flap 6, the cardboard becomes larger and the number of cut ends increases by the length. Therefore, by setting the flap lengths of the holding flap 5 and the joining flap 6 to be the same, it is possible to avoid a rise in the cost of the cardboard.

At the time of producing the packaging box 1, first, the side plates 3 a to 3 d and the joining flap 6 are folded along the fold line, so that the joining flap 6 is attached to the inside of the side plate 3 b with an adhesive, an adhesive tape or Join with a stapler. Next, after the bottom plate flap 2a is bent with respect to the side plate 3a, the bottom plate flaps 2b and 2c are bent with respect to the side plates 3b and 3c, and the bottom plate flap 2b is provided at both ends of the bottom plate flap 2a. , 2c. Next, the bottom plate flap 2d is bent with respect to the side plate 3d, and its tip is inserted toward the back surface (inner surface) of the bottom plate flap 2a. Thereby, as shown in FIG. 4, the bottom plate flaps 2a to 2d are locked, and one bottom plate 2 is completed. Subsequently, after the packaging object is accommodated in the packaging box 1 in this state, the closing flaps 7, 7 are bent with respect to the side plates 3b, 3c. Next, after the insertion flap 8 is bent with respect to the top plate 4, the top flap 8 is inserted between the side plate 3a and the packaging object by bending the top plate 4 with respect to the side plate 3d. Thereafter, if necessary, the top plate 4 and the side plate 3a are sealed with an adhesive tape, so that the packaging of the object to be packaged (accommodation in the packaging box 1) is completed as shown in FIG. The box 1 is made into a rectangular parallelepiped box. In this state, the gripping flap 5 protrudes in a direction orthogonal to the side plate 3b.

Next, the packaging boxes 1, 1. At this time, as shown in FIG. 2, the packaging boxes 1, 1,... Are accommodated in the outer box 11 so that the side plate 3b faces upward. Then, the lids 11a, 11a,... Of the outer box 11 are folded to close the opening. In this case, since the holding flaps 5, 5,... Of the packaging boxes 1, 1,... Are connected to the top plate 4 via the perforated lines BL, the lids 11a, 11a are folded. Then, the portion of the perforation processing line BL is bent by the force, and the gripping flap 5 is brought into surface contact with the side plate 3b. At this time, for example, it is assumed that the gripping flap 5 of the packaging box 1a is tilted down in a direction of contacting the side plate 3b of the packaging box 1b, and the gripping flap 5 of the packaging box 1b is tilted down in a direction of contacting its own side plate 3b. I do. In this case, in this packaging box 1, since the length of each flap of both gripping flaps 5, 5 is defined to be about １ ／ of the height of the side plate 3b (distance L2 shown in FIG. 3), Contact (interference) between the gripping flaps 5 and 5 in 1a and 1b is avoided, and damage to the gripping flaps 5 is prevented. Thereafter, the lids 11a and 11a are sealed with an adhesive tape, whereby the housing of the packaging boxes 1, 1... Is completed.

On the other hand, in a retail store or the like that has received the outer box 11, first, the adhesive tape is peeled off from the outer box 11, and then the lids 11a are opened. Next, the gripping flap 5 that is in contact with the side plate 3b is raised and gripped, and the gripping flap 5 in this state is pulled upward to lift the packaging box 1 from the outer box 11. At this time, only the force in the direction of extension of the top plate 4 and perpendicular to the perforation line BL is applied to the gripping flap 5, and the gripping flap 5 is moved along the perforation line BL. There is no force to break the force. Accordingly, unintended tearing of the grip flap 5 is avoided. In addition, since the base end side of the gripping flap 5 (the portion where the perforation processing line BL is formed) is formed longer than the front end side, the force when pulling up the front end side is dispersed. Unintended tearing at the perforation line BL is avoided. Thus, the packaging box 1 can be safely and easily taken out of the outer box 11 without breaking the space between the side plates 11b and 11c of the outer box 11 or tearing the outer box 11 with a blade. Further, when one packaging box 1 is taken out of the outer box 11, a space is formed where a hand can be inserted into a portion where the taken out packaging box 1 was stored. Therefore, the gripping flap 5 may be gripped and pulled up, or the packaging box 1 itself may be gripped and easily taken out. Thereafter, when displaying the packaging box 1 taken out of the outer box 11 in that state, the gripping flap 5 is cut off along the perforation processing line BL. Thereby, the packaging box 1 is formed in a rectangular parallelepiped shape like the conventional packaging box 51.

As described above, according to the packaging box 1, since the holding flap 5 is formed on one side of the top plate 4 via the perforated line BL, when the packaging flap 5 is stored in the exterior box 11, The packaging box 1 can be taken out by pulling the gripping flap 5 without tearing the box 11. Therefore, even a weak person can safely and easily take out the packaging boxes 1, 1... From the outer box 11. Further, since it is not necessary to perform perforation processing on the outer box 11, unintentional dismantling of the outer box 11 during transportation is avoided, and the contents (in this case, the packing boxes 1, 1,. Scratches can be prevented. Further, since the holding flaps 5 are connected to the top plate 4 via the perforation lines BL, the holding flaps 5 can be easily removed from the top plate 4 after the removal from the outer box 11 is completed. In that case, it can be formed in a rectangular parallelepiped shape similar to the conventional packaging box 51. Thus, when the gripping flap 5 is unnecessary, it can be easily removed without using a blade or the like. Furthermore, since the holding flap is provided without providing a hole or the like in the outer casing of the packaging box 1, a reduction in the strength of the packaging box can be avoided.

Further, the blank B1 is formed by forming the flap length of the gripping flap 5 to be less than or equal to the flap length of the joining flap 6 (in the embodiment of the present invention, both flap lengths are the same). In this case, it is possible to avoid an increase in the size of the cardboard for performing the operation, so that it is possible to avoid an increase in the manufacturing cost of the blank B1 (packaging box 1). Furthermore, since the flap length of the gripping flap 5 is formed to be 以下 or less (in this case, ４) of the height of each of the side plates 3a to 3d, the packaging boxes 1 adjacent to each other in the outer box 11 are formed. , 1 can be prevented from coming into contact with each other even if the gripping flaps 5, 5 are tilted in a direction approaching each other, thereby preventing the gripping flaps 5 from being damaged. . In this case, by forming the gripping flap 5 such that one side of the base end side is longer than one side of the front end side, the base flap side where the fold line or the perforated line is formed is formed. As a result, unintended tearing of the grip flap 5 can be prevented. Further, since the front end portion is formed to be narrow, the grip flap 5 is gripped near the center when the grip flap 5 is gripped when the packaging box 1 is pulled up. Therefore, since the packaging box 1 is lifted directly above, the packaging box 1 can be pulled up smoothly while preventing the gripping flap 5 from being unintentionally torn.

The present invention is not limited to the above-described embodiment of the present invention, and can be appropriately changed. For example, in the embodiment of the present invention, the packaging box 1 in which the holding flaps 5 are continuously provided on one side of the top plate 4 has been described, but the holding flaps in the present invention are configured to be continuously provided on the top plate. The present invention is not limited to this, and a gripping flap 25 may be continuously provided on the upper side of the side plate 3a via a perforation line BL as in a packaging box 21 shown in FIGS. As shown in FIG. 6, the packaging box 21 is housed in the exterior box 11 with the top plate 4 facing upward together with the other packaging boxes 21, 21,. Similarly, it is made into a rectangular parallelepiped shape that can package video tape cassettes and optical recording media. This packaging box 21 is manufactured by bending a blank B21 shown in FIG. 7 along a fold line. In this case, as shown in the figure, in the blank B21, the flap length of the gripping flap 25 (the distance L1a shown in the figure) is １ ／ of the width of the top plate 4 (the distance L2a shown in the figure). It is formed so as to be as follows (in this example, for example, about 1/5 to 1/6). Therefore, similarly to the packaging box 1, in a state where the packaging flaps 25 and 25 of the adjacent packaging boxes 21 and 21 are housed in the outer box 11, contact with each other is avoided. According to the packaging box 21, the packaging flap 25 can be gripped and the packaging box 21 can be lifted from the outer box 11. The box 21 can be taken out of the outer box 11.

In the embodiment of the present invention, the grip flap 5 in which one side on the base end side is formed in a trapezoid longer than one side on the distal end side is described as an example. However, the present invention is not limited to this. For example, at least the bases at both ends of the packaging box 21a shown in FIG. 9 (the drawing shows a blank B21a for the packaging box 21a) are shown. The end on the end side may be formed in an arc shape concave toward one side (the perforated line BLa in this example) on the base end side. According to this configuration, the force at the time of pulling up the distal end side of the gripping flap 25a is more reliably dispersed at the base end side (the portion where the perforation processing line BLa is formed). Can be prevented from being unintentionally broken. Further, in this packaging box 21a, the perforated line BLa provided on the base end side of the gripping flap 25a is different from the above-described perforated line BL, and the perforated line forming pitch on both end sides thereof is different. However, it is coarser than the perforation forming pitch at the center. For this reason, since both ends of the perforated line BLa are unlikely to be broken, unintended breakage of the perforated line BLa when the gripping flap 25a is gripped and pulled up can be avoided. The configuration of the grip flap 25a and the perforation line BLa can be applied to the grip flap 5 of the packaging box 1.

Also, in the embodiment of the present invention, the packaging box 1 having the lock type bottom plate 2 has been described, but the structure of the bottom plate is not limited to this, and the sack type structure and the one-touch type are provided. In addition to the structure, a wrap round structure can be adopted when performing box making by an automatic machine. Further, the configuration of one plate surface by the lock type structure, the sack type structure, the one-touch type structure, the wrap round structure, and the like is not limited to the bottom plate 2, and the packaging box 31 shown in FIG. , A blank B31 for the packaging box 31 is shown), and the bottom plate 32 is formed as a single sheet, and side plates corresponding to the side plates 3b and 3c in the packaging box 1 are constituted by the side plate flaps 33a to 33h. Is also good. Further, in the embodiment of the present invention, an example in which the grip flap 5 is formed in a trapezoidal shape has been described. However, the present invention is not limited to this, and the grip flap 5 may be formed like a grip flap 35 of the packaging box 31 shown in FIG. By making the corners on both ends thereof round, the base end side may be formed longer than the tip end side. Similarly, the flap for insertion in the present invention can have a shape with rounded corners, like the flap for insertion 38 shown in FIG.

[Effect of the invention]

 As described above, according to the packaging box of the present invention, the holding flap is formed via a fold line or a perforated line on at least one side of at least one of the top plate and the bottom plate on which the insertion flap is formed. When stored in an outer box, the packaging box can be taken out by pulling the gripping flap without tearing the outer box. Therefore, even a weak person can safely and easily take out the packaging box from the outer box. Also, since there is no need to perforate the outer box, unintentional dismantling of the outer box during transportation is avoided, and the contents (in this case, the packing box) are prevented from being damaged. be able to. Furthermore, by connecting the gripping flap to the top plate or the bottom plate via the perforation line, the gripping flap can be easily removed from the top plate or the bottom plate after the removal from the outer box is completed. Wear. Therefore, when the gripping flap is unnecessary, it can be easily removed without using a blade or the like. Further, by providing the holding flap without providing a hole or the like in the outer casing of the packaging box, it is possible to avoid a reduction in the strength of the packaging box.

Further, according to the packaging box of the present invention, the flap length of the holding flap is set to be equal to or less than the flap length of the joining flap, so that the cardboard for forming the packaging blank is formed. Since an increase in size can be avoided, it is possible to avoid an increase in blank (packaging box) manufacturing costs.

Further, according to the packaging box of the present invention, the flap length of the gripping flap is formed to be not more than の of the height of each side plate, so that each of the adjacent packaging boxes in the outer packaging box is formed. Even if the holding flaps are tilted in the direction of approaching each other, contact between the two gripping flaps is avoided, thereby preventing the gripping flaps from being damaged.

[0032] According to the packaging box of the present invention, the gripping flap is formed on one side of the side plate that is in contact with the insertion flap in the box-making state via a fold line or a perforated line, so that the exterior box is formed. When the packaging box is stored, the packaging box can be taken out by pulling the gripping flap without tearing the outer box. Therefore, even a weak person can safely and easily take out the packaging box from the outer box. Also, since there is no need to perforate the outer box, unintentional dismantling of the outer box during transportation is avoided, and the contents (in this case, the packaging box) are prevented from being damaged. be able to. Further, by connecting the holding flap to the top plate or the bottom plate via the perforation line, the gripping flap can be easily removed from the top plate or the bottom plate after the take-out from the outer box is completed. Therefore, when the gripping flap is unnecessary, it can be easily removed without using a blade or the like. Further, by providing the holding flap without providing a hole or the like in the outer casing of the packaging box, it is possible to avoid a reduction in the strength of the packaging box.

Further, according to the packaging box of the present invention, the flap length of the gripping flap is set to one of two sides orthogonal to one side of the at least one of the top plate and the bottom plate where the insertion flap is formed. / 2 or less, so that even if the gripping flaps of the adjacent packaging boxes in the outer box are tilted in the direction approaching each other, contact between the gripping flaps is avoided, thereby In addition, it is possible to prevent the grip flap from being damaged.

[0034] Further, according to the packaging box of the present invention, one side of the base end side is preferably longer than the one side of the front end side, and preferably, one side of the base end side is set as a bottom side, By forming the gripping flap in a trapezoidal shape with one side at the tip end side as the upper side, the force can be dispersed at the base end side where the fold line or perforation line is formed. Unintended tearing of the grip flap can be prevented. Also, by forming the tip portion narrower, when gripping the gripping flap when pulling up the packaging box, the gripping flap is gripped near the center thereof, and as a result, the packaging box is pulled straight up. The packaging box can be lifted smoothly while preventing unintended tearing of the gripping flap. In this case, since the end of the grip flap on the side of the base end side is formed in an arc shape recessed toward one side of the base end side, the force for pulling up the packaging box is ensured on the base end side. Therefore, unintended tearing of the gripping flap can be more reliably prevented. Furthermore, by making the perforation forming pitch on the both ends side coarser than the central perforation forming pitch, both ends of the perforated processing line are less likely to be torn, so that unintended tearing can be more reliably prevented. it can.
