Description

  The present invention relates to a method for facilitating opening of a box and a box that can be easily opened in a box having a pair of outer flaps on an opening surface that is sealed using an adhesive tape.

A box having a pair of outer flaps on the unsealing surface is provided with an outer flap (continuously provided on the upper edge of the pair of end face plates provided on the upper edge of the pair of end face plates) at the time of sealing. Edges on the opposite sides of the ones arranged on the upper side form a seam. When using an adhesive tape for sealing the box, the adhesive tape is applied to the seam and its periphery and the end face plate.
When the box thus sealed is opened, generally, the adhesive tape is cut and opened with a cutter or the like, or the adhesive tape is peeled off and opened. In contrast to such an opening method, the following three methods have been conventionally proposed as a device for easily opening a box sealed with an adhesive tape.

The first method is a method in which the adhesive tape is easily peeled from the box and opened. Patent Document 1 shows an example of the first method, and a box is cut to make it easy to peel off the adhesive tape.
The second method is to seal the box using an adhesive tape having a notch or perforation, and to easily open the box so that the adhesive tape can be easily cut from the notch or perforation when opened. It is. Examples thereof include those in which cuts and holes are uniformly made in advance in the adhesive tape as in Patent Document 2, and those in which a perforation is provided in the center of the adhesive tape in advance as in Patent Document 3.
In the third method, after the box is sealed with an adhesive tape, a perforation is formed along the seam formed by the outer flap as in Patent Document 4, and the perforation is opened at the time of opening. is there.

The conventional method of cutting and opening adhesive tape with a cutter, etc., in general, requires a cutter at all times, and injuries the contents or injuries when using the cutter. There was a fear of doing. Also, with the conventional method of peeling and opening the adhesive tape, it is not easy to peel off the adhesive tape that is strongly adhered to the box, and it takes time and effort. There was a problem that it could hurt, and it could not be removed cleanly.
In order to solve the above-mentioned problem that is difficult to peel off, the method of Patent Document 1 makes a cut in the end face plate of the box or the center of the lid near the adhesive tape, makes it easy to break the cut and hold the adhesive tape, and make it easy to peel off. Is the method. However, when using this method, the position of the cuts made on the box is fixed, so it is necessary to apply the adhesive tape accurately, which requires attention to the work, and the opening method is difficult to understand intuitively. In order to break the cut, a force to push from the side is necessary, and there is a problem that it is difficult to stably peel off the adhesive tape.

In the method of Patent Document 2, since there are uniform cuts, holes, or perforations in the pressure-sensitive adhesive tape, there is a problem that the pressure-sensitive adhesive tape is broken when an unintended force is applied during the sealing operation. In the method of Patent Document 3, it is difficult to place the adhesive tape with the perforation located at the joint, and there is a problem that the adhesive tape may break during the sealing operation.
In Patent Document 4, since the perforation is made in the adhesive tape facing the joint after sealing, there is no problem that the adhesive tape breaks during sealing or the problem that the perforation of the adhesive tape and the joint of the box do not match. In particular, when the perforation is formed in all the joint portions between the outer flaps, there is a possibility that the adhesive tape containing the perforation may be cut when a force is applied from above during transportation.
Further, in the conventional technology, since the box can be opened only on the top surface, there is a problem that it is difficult to take out the contents when the contents are accommodated in the box without any gaps. In addition, since only the top surface could be opened in the past, as long as the product is not taken out from the box (with the product as a content in the box), the display and display of the product as a content is possible. There was a problem that could not.

  The present invention has been made paying attention to such problems of the prior art, and does not require any special attention or device during sealing work, is simple and easy to understand, and uses no equipment or strong force. It is an object of the present invention to provide a method for facilitating the opening of a box and a box that can be easily opened, which can be stably opened and is difficult to open easily even if an unintended force is applied from above during transportation. To do. The present invention also provides a method for facilitating the opening of a box and a box that can be easily opened so that the contents can be easily taken out from the box and the contents can be displayed and displayed only by opening the box. For the purpose.

  A method for facilitating opening of a box according to the present invention is a box including a pair of side plates, a pair of end surface plates, and a pair of outer flaps that are respectively continuous with an opening portion of each side plate. The adhesive tape is cut in the short direction of the adhesive tape into the seam formed by the edges on the opposite sides of the outer flaps on the opening side when sealed and the vicinity thereof and the vicinity of the seam in each end face plate A method of facilitating opening of a sealed box by applying an adhesive tape that is easy to perform, wherein (a) one outer flap of the pair of outer flaps, (b) one of the pair of outer flaps A portion of the outer flap attached to the outer flap and a side plate continuous with the outer flap, or (c) a side plate continuous with one outer flap of the pair of outer flaps. Including and beyond A first step of forming a breaking portion for separating the first portion and the other outer flap of the pair of outer flaps and forming a fold line (fold) substantially parallel to the seam; A second step of separating the portion including the portion where the adhesive tape in the outer flap is attached and the other portion from each other by the breaking portion, and the adhesive tape in the one outer flap is attached. The part including the bent part is lifted from the cut edge side with the joint as a rotation axis and rotated to cut the part of the adhesive tape facing the gap between the outer flap and the end plate. 3 steps, with the other outer flap facing the raised portion through the seam as a rotation axis with a fold line (fold) formed in the other outer flap as the rotation axis Is rotated to lift from the fourth step of cutting the portion of the adhesive tape that faces the gap of the other outer flap and the end face plates, it is intended to include.

  The seam formed by the opposite edges of the outer flap at the time of sealing according to the present invention is only the edges of the pair of outer flaps, such as a box that seals each edge of the pair of outer flaps. It includes not only the seam formed, but also a seam composed of an edge of one outer flap and a portion of the other outer flap opposite to the edge, like a box in which the outer flaps are overlapped and sealed.

  In the present invention, the adhesive tape that is easy to cut in the short direction is a kraft adhesive tape based on paper, a thin adhesive tape, and a special film that is easy to tear in the short direction of the adhesive tape. It is an adhesive tape, an adhesive tape with a small scratch or notch on the periphery of the edge in the short direction of the adhesive tape. These are pressure-sensitive adhesive tapes that can cut the pressure-sensitive adhesive tape in the short direction only by applying a force that tears it with a finger without using a blade. In addition, when such an adhesive tape is used to seal a box, the adhesive tape is attached to the box and it is difficult to apply a force that tears the adhesive tape to the extent that it is cut. The adhesive tape is not easily cut by an unintended force applied to the tape.

In the present invention, the breaking portion (breaking mechanism) is a portion having a breaking mechanism capable of breaking a cardboard or paper, which is a material of the box, and is used, for example, for opening a box. Band-like zippers, linear zippers, perforations with cuts and slits arranged at regular intervals, liner cuts, half cuts, cut tapes, etc. are used alone or in combination.
(A) of the present invention includes a portion including a portion where the breaking portion (breaking mechanism) is formed on the outer flap on the opening surface side, and the adhesive tape in the outer flap is pasted by breaking. It is formed so that it can be separated from the part.
It is possible to lift the part of the outer flap by inserting a finger from the part cut off using the part for breaking (mechanism for breaking). Even if the outer flap portion is cut off from the box, the portion of the outer flap to which the adhesive tape is attached is connected to the opposite outer flap by the adhesive tape.

  In the method for facilitating the opening of the box according to the present invention, the outer flap is first utilized by utilizing the mechanism for breaking the breaking portion for the box sealed with the adhesive tape that is easy to cut in the short direction. The part including the part where the said adhesive tape was stuck inside is cut off from the other part of the box. Next, when the joint between the outer flaps is used as a rotation axis and the part including the part where the adhesive tape is affixed in the outer flap is lifted from the side separated and rotated, the joint is used as a fulcrum in the process. In addition to the lever principle, a tearing force is intensively applied to the lifting side portion of the adhesive tape facing the gap between the outer flap and the end plate, and as a result, the outer flap and the end plate The adhesive tape (the portion of the adhesive tape that fixes the outer flap and the end face plate) facing the gap is cut. After that, the other outer flap other than the first raised outer flap on the opening side is lifted and rotated from the joint portion of the outer flap around the fold line (fold) formed on the other outer flap. If it does, since force will concentrate on the part by the side of the raising in the said adhesive tape which opposes the clearance gap between the outer flap to lift and an end surface board, an adhesive tape can be cut | disconnected easily.

In order to easily cut the adhesive tape as described above, it is important to make a rotation shaft so that the lifted outer flap rotates. When there is no rotating shaft, even if the outer flap is lifted, a force is applied to the entire adhesive tape facing the gap between the outer flap and the end face plate. Therefore, a strong force is required for cutting the adhesive tape.
The outer flap separated by the breaking portion can use the joint as a rotation axis. However, if the length of the outer flap left last is long in the vertical direction at the joint of the outer flap, it becomes difficult to stably use the edge of the last left outer flap on the side plate side as the rotation axis. . Therefore, the adhesive tape can be easily and stably cut by forming a fold line (fold) as a rotation axis in a portion not far from the joint.
The formation position of the fold line (fold) is preferably within 15 cm from the joint in the general cardboard thickness, but it varies depending on the thickness and material of the plate constituting the box.

In this way, in the method for facilitating the opening of the box of the present invention, the breaking portion (breaking mechanism) is used without cutting the joint portion in the adhesive tape that fixes the outer flaps. Further, by lifting and rotating a part of the outer flap about the joint as a rotation axis, in addition to the principle of leverage, a force that tears a part of the adhesive tape is intensively applied, whereby the outer flap and the end plate Easily cut the adhesive tape facing the gap between them, and lift and rotate the last remaining outer flap from the joint part with the fold line (fold) formed on the other remaining outer flap as the rotation axis It is characterized by intensively applying a tearing force to a part of the adhesive tape, cutting the adhesive tape facing the gap between the last outer flap and the end face plate, and opening it. That.
In addition, by forming the breaking portion (breaking mechanism) near the side plate in the outer flap, even if an unintended force is applied from above, the force is distributed to the side plate and the outer flap is not easily broken. You can also
Therefore, the easy-opening box of the present invention does not require special care or equipment during the sealing operation, and when opening, it simply breaks and lifts the outer flap. It is an opening method that is unnecessary, can be opened stably and easily, and is not easily opened even when an unintended force is applied from above during transportation.

  In addition, (b) and (c) of the method for facilitating the opening of the box of the present invention are such that the breaking portion (breaking mechanism) is attached to the outer flap and the adhesive tape in the side plate. The part including the part and the other part are formed so as to be separable from each other, and (b) is one of the pair of outer flaps and the side plate continuous with the outer flap is provided with a breaking part. Form. (C) forms a breaking portion on a side plate that is continuous with one outer flap of the pair of outer flaps.

By forming the breaking portion (breaking mechanism) as described above, according to the present invention, part or all of the outer flap and the side plate can be removed together. Can be taken out from the opening on the side plate side, making it easier to take out the contents of the box (in the prior art, fixing the joint between the outer flaps by cutting or removing the adhesive tape) Because it was the opening method of canceling, only the top side (outside flap side) could be opened).
Therefore, even if a general and inexpensive A-type box is used according to the present invention, part or all of the side plate is removed together with the outer flap by the opening operation, so that an opening is also formed in the side plate. It becomes like this. Therefore, according to the present invention, the contents can be exposed from the opening of the side plate even when the contents are housed in the box. Therefore, the contents can be displayed and displayed on the box. It can also be used as a box that can be used.
Furthermore, in the present invention, when the breaking portion (breaking mechanism) is formed only on the side plate, compared to the case where the breaking portion (breaking mechanism) is formed on the outer flap. Even if an unintended force is applied to the outer flap from above, the outer flap can be hardly broken.

The box that can be easily opened according to the present invention includes a pair of side plates, a pair of end plates connected to the side plates, and a pair of outer flaps that are continuous with the opening side edges of the side plates, respectively. And a seam formed by edges facing each other in the pair of outer flaps on the unsealing side at the time of sealing and the vicinity thereof and the vicinity of the seam in each end face plate It is a box sealed by sticking an adhesive tape that is easy to cut in the short direction,
(A) One outer flap of the pair of outer flaps, (b) One outer flap of the pair of outer flaps and a side plate continuous with the outer flap, or (c) One of the pair of outer flaps The side plate that is continuous with the outer flap is formed with a breaking portion for separating the portion including the portion to which the adhesive tape is attached in the outer flap from the other portion, and the other side of the opening surface In the outer flap, a fold line (fold) that is substantially parallel to the joint serving as a rotation axis for rotating a part of the other outer flap is formed between the joint and the side plate. is there.

  The operation and effect of the easily openable box invention are the same as the invention of the method for facilitating the opening of the box.

In a box having only one outer flap on the opening surface represented by a corrugated cardboard box called B-type, opening the zipper on the outer flap makes it easy and easy to open.
However, the box with a pair of outer flaps represented by the corrugated cardboard box called A-type, the outer flap and the end plate are fixed with adhesive tape. Since the box cannot be opened, the box and the opening method as in the present invention have not been used. For this reason, various unsealing methods as described in the prior art have been proposed, all of which have advantages and disadvantages.
According to the present invention, a pair of outer flaps and an end face plate are fixed to each other with an adhesive tape, but a breaking portion (breaking mechanism) such as a zipper formed on the outer flap, a fold line (fold), and a short side By using the adhesive tape that is easy to cut in the direction, it is possible to concentrate the tearing force in addition to the lever principle on the part of the adhesive tape that faces the gap between the outer flap and the end face plate. Therefore, the adhesive tape can be broken and opened very easily.

In this way, using the present invention, even in an inexpensive A-type box, it is possible to open very easily by forming a breaking part (breaking mechanism) such as a zipper and a broken line (fold), thereby reducing the cost. It is possible to improve the workability at the time of opening.
Furthermore, in the prior art, since it was an opening method of releasing the fixation of the outer flaps by cutting or removing the adhesive tape, only the top surface side could be opened. On the other hand, in the opening method of the present invention, the one outer flap and / or the side plate that is continuous with the outer flap and / or the portion including the portion where the adhesive tape in the side plate is pasted. By forming a breaking part (breaking mechanism) that can be separated from each other, the outer flap and the side plate can be removed together. Since the contents can be taken out from the openings on the top surface side and the side plate side with the outer flap, it is easier to take out the contents from the box. Further, even in the A-type box, only the opening operation of removing the outer flap and a part of the side plate together can be performed, and a part of the side plate on the outer flap side can be used as an opening. The contents can be exposed from the opening of the side plate even when the contents are stored in the box, and the box can be used as a box for displaying and displaying the contents (products). become.

It is a perspective view which shows the cardboard box sealed with the adhesive tape in Example 1 of this invention. It is an expanded view of the box of FIG. It is a perspective view for demonstrating the opening method of the box in Example 1. FIG. FIG. 6 is a perspective view for explaining a first modification and a second modification of the first embodiment. FIG. 6 is a development view of a box of Example 2. It is a perspective view for demonstrating the opening method of the box in Example 2. FIG.

  For example, as shown in FIG. 1, the box used in the embodiment of the present invention includes outer flaps 1 and 2 provided to be continuous with at least the edges of the pair of side plates 4 on the side of the opening surface, 4 and a pair of end face plates 3 that are continuous to each other. The outer flaps 1 and 2 are positioned above the inner flaps provided so as to be continuous with the edge of the pair of end face plates 3 on the opening surface side. When the box is sealed, the edges of the outer flaps 1 and 2 facing each other form a seam 7, and the edges of the outer flaps 1 and 2 facing each other and the vicinity thereof and the end plate 3 are aligned. The vicinity of the eyes 7 is sealed by fixing with the adhesive tape 6.

The pressure-sensitive adhesive tape 6 used for sealing is a pressure-sensitive adhesive tape that can be cut or easily cut with a finger or the like in the short direction. As such an adhesive tape, in the following examples, a kraft adhesive tape that is often used for sealing a box is used, but is not limited to this. For example, a thin OPP adhesive tape or a special film is used. It may be an OPP adhesive tape that can be cut by hand using a base material, or an adhesive tape that has scratched the periphery of the edge. In addition, in the figure of an Example, in order to show the joint 7 of the outer flaps 1 and 2 in an easy-to-understand manner, the opaque craft adhesive tape 6 is shown transparently.
In the following examples, the zipper 5 often used for breaking the cardboard box is used as the breaking mechanism for the breaking portion (breaking mechanism), but the invention is not limited to this. A perforation lined with slits, a liner cut, a half cut, a cut tape, or the like may be used alone or in combination.
In the following embodiments, unless otherwise specified, “a seam formed by edges of at least one outer flap (edges on opposite sides of a pair of outer flaps) at the time of sealing” is simply referred to as “joint”. There is a case.

Example 1
A method for facilitating opening of the first embodiment of the present invention and a box that can be easily opened will be described with reference to FIGS.
In the box of the first embodiment, as shown in FIG. 1, the opposing edges of the outer flaps 1 and 2 and the vicinity thereof and the vicinity of the joint 7 of the end face plate 3 are fixed by the craft adhesive tape 6. ing. One outer flap 1 on the opening surface side is provided with a belt-like zipper 5 that linearly connects the edges of the left and right end face plates 3 of the outer flap 1 to each other. Further, a fold line (fold) 10 is formed in the outer flap 2 substantially parallel to the joint 7.
FIG. 2 is an exploded view of the box of FIG. As shown in FIG. 2, the outer flap 1 has an outer flap 1 so that when the zipper 5 is cut off, the portion surrounded by the zipper 5 and the left and right slots 9 of the outer flap 1 is separated from the other portions. A belt-like zipper 5 connecting the left and right slots 9 is formed. Further, a fold line (fold) 10 is formed in the outer flap 2 substantially parallel to the seam 7 formed by the outer flap during sealing.

  FIG. 3 is a diagram for explaining the method of opening the box. In the first embodiment, the outer flap 1 on which the zipper 5 is formed by cutting out the zipper 5 includes a portion including the portion where the craft adhesive tape 6 is pasted in the outer flap 1 and other portions. And separated. FIG. 3 (1) shows a portion including a portion where the craft adhesive tape 6 is pasted in the outer flap 1 after the zipper 5 is cut from the edge on the side where the zipper 5 is cut off. Is a state in which the pressure-sensitive adhesive tape 6 that is lifted and turned upward and is opposed to the gap between the outer flap 1 and the end face plate 3 is cut. 3 (2) shows that the outer flap 2 in which the zipper 5 is not formed is moved upward from the edge portion forming the seam 7 of the outer flap 2 with the fold line (fold) formed in the outer flap 2 as a rotation axis. The state is shown in which the adhesive tape 6 that has been lifted and rotated and opposed to the gap between the outer flap 2 and the end face plate 3 is cut. When the outer flap 2 is further lifted, it can be opened as shown in FIG. Even after opening, the two outer flaps 1 and 2 remain connected by the craft adhesive tape 6 at the joint 7.

Next, operations and effects in the first embodiment will be described with reference to FIGS. 1, 2, and 3. FIG. When the zipper 5 shown in FIG. 1 is excised, the outer flap 1 on which the zipper 5 has been formed is a portion fixed with the craft adhesive tape 6 in the outer flap 1 (such as a joint 7) with the portion where the zipper is present as a boundary. ) And a portion continuous with the side plate 4 in the outer flap 1. As shown in FIG. 3 (1), after cutting out the zipper 5, the part including the part fixed with the craft adhesive tape 6 in the outer flap 1 is separated from the edge on the side where the zipper 5 is cut off. In addition to the lever principle with the seam 7 as a fulcrum, the lifting side of the craft adhesive tape 6 facing the gap between the outer flap 1 and the end face plate 3 is applied to the lifting side of the craft adhesive tape 6. Since a tearing force is intensively applied, a portion between the outer flap 1 and the end face plate 3 in the craft adhesive tape 6 is cut with a relatively light force.
Further, as shown in FIG. 3 (2), the outer flap 2 in which the zipper 5 is not formed is taken as the outer flap with a fold line (fold) substantially parallel to the joint 7 formed in the outer flap 2 as a rotation axis. When lifting up and rotating from the edge of the seam 7 side of 2, the force concentrated on the part of the seam side in the craft adhesive tape 6 facing the gap between the outer flap 2 and the end face plate 3 Can be cut even with a weak force, and the box can be opened easily.

  As described above, the cardboard box according to the first embodiment lifts the portion including the portion to which the craft adhesive tape 6 is attached in the outer flap 1 as described above after cutting the zipper 5 in the outer flap 1. Furthermore, it can be easily opened simply by lifting the outer flap 2 as described above. Therefore, according to the first embodiment, the person who opens the box can intuitively open the box without hesitation. In addition to the lever principle with seam 7 as a fulcrum, the force concentrates on a part of the craft adhesive tape that secures the outer flap 2, so the craft adhesive tape can be cut with a relatively light force. And can be opened stably.

Next, a first modification of the first embodiment of the present invention will be described with reference to FIG.
In contrast to the linear zipper 5 of the first embodiment, in the first modification of the first embodiment, as shown in FIG. 4 (1), the left and right sides of the outer flap 1a on the opening surface side (the direction in which the joint 7a extends) ) Are formed across the outer flap 1a and the side plate 4a connected to the outer flap 1a. The zipper 5a is provided with an opening start portion 11a (a portion to put a finger or the like when the opening person performs an opening operation) in an intermediate portion near the side plate 4a in the zipper 5a.

In the first modification, the unsealing person puts his / her finger from the unsealing start portion 11a of the zipper 5a, causes the portion surrounded by the zipper 5a and the outer flap 1a in the side plate 4a, and separates it from the side plate 4a. The part of the side plate 4a that is cut off is connected to a part of the outer flap 1a.
Furthermore, when this connected portion (the portion surrounded by the zipper 5a in the outer flap 1a, the edge on each end plate 3a side and the joint 7a) is lifted from the side plate side, the zipper 5a portion breaks. The craft adhesive tape 6a facing the gap portion between the outer flap 1a and the end face plate 3a is continuously cut by the turning operation with the eyes 7a as the rotation axis.
Thereafter, as in the first embodiment, the outer flap 2a is lifted and rotated upward from the edge side forming the joint 7a of the outer flap 2a, with a fold line (fold) 10a formed on the outer flap 2a as a rotation axis. When the craft adhesive tape 6a facing the gap between the outer flap 2a and the end face plate 3a is cut, it is opened.

As described above, according to the first modification, the craft adhesive tape in which the opener faces the breakage of the zipper 5a portion in the side plate 4a and the outer flap 1a and the gap portion between the outer flap 1a and the end plate 3a. Since the cutting of 6a is performed continuously, the opening method can be opened more easily.
Further, the effects of the first modification are as follows. In the prior art, when the adhesive tape is cut with a knife or peeled off and opened, only the opening surface with the outer flap is opened, so when the contents are packed without gaps, There was a problem that it was difficult to take out the contents. On the other hand, in the first modification, part of the side plate 4a is also removed at the same time, so that the contents of the box can be taken out from the opening on the side plate 4a side, and the contents can be easily taken out. In addition, since a part of the side plate 4a and the outer flaps 1a and 2a can be opened together, this box can be used as a display box for contents and a display box.

Next, a second modification of the present invention will be described with reference to FIG.
In the first embodiment, the zipper 5 is formed on the outer flap 1. On the other hand, in the second modification, as shown in FIG. 4 (2), a zipper 5b connected to the left and right slots 9 of the outer flap 1b is formed on the side plate 4b.
Next, the operation and effect of the second modification will be described with reference to FIG.
As for the unsealing method, when the zipper 5b is caused by putting a finger from the unsealing start portion 11b in the middle of the zipper 5b formed on the side plate 4b, the left and right slots 9 of the outer flap 1b are connected, and the outer flap 1b in the side plate 4b A portion connected to the other portion is separated from other portions. Next, when the portion of the side plate 4b connected to the outer flap 1b and the outer flap 1b connected thereto are lifted and rotated from the side plate 4b with the joint 7b as a rotation axis, the outer flap 1b and the end plate 3b are rotated. The craft adhesive tape 6b facing the gap portion between them is easily cut. Thereafter, as with the first embodiment, the last remaining outer flap 2b is lifted to be opened.

In the second modification, since the zipper 5b is formed on the side surface plate 4b, the zipper 5b is not easily broken even when a force from above is applied, so that it can have almost the same sealing force as a normal box.
In addition, the effect that the contents of the box can be easily taken out and can be used as a display or display box is the same as that of the first modification.
When the zipper 5b is formed on the side plate 4b, any shape can be used as long as the zipper 5b is connected to the left and right slots 9 (see FIG. 2) of the outer flap 1b on the unsealing surface side connected to the side plate 4b. Even this zipper has the same operation and effect as the second modification.

(Example 2)
A method for facilitating opening of the second embodiment of the present invention and a box that can be easily opened will be described with reference to FIG.
The box of the second embodiment is called the A-2 type in the old JIS format, and as shown in FIG. 5, the direction perpendicular to the joint of one of the outer flaps on the unsealed surface side of the box This is a box having a long outer flap 2c, having a breaking portion (breaking mechanism) on the short outer flap 1c side, and having a fold line (fold) on the long outer flap 2c.
When the box shown in the plan view of FIG. 5 is assembled, the outer flap 1c is overlapped on the outer flap 2c at the time of sealing, and a seam 7c is formed by the edge of the outer flap 1c and the portion in the outer flap 2c facing it. The In the second embodiment, the vicinity of the edge (joint 7c) in the outer flap 1c, the vicinity of the edge (joint 7c) of the outer flap 1c in the outer flap 2c, and the outer flap in the end face plate 3c. The vicinity of the edge 1c (joint 7c) is fixed to each other by the craft adhesive tape 6c. The appearance after sealing is the same as in FIG. 1, and the outer flap 1c on the unsealing surface side is a belt-like shape that linearly connects the left and right edges of the outer flap 1c (the direction in which the joint 7c extends) on the end face plate 3c side. Zipper 5c is provided, and a fold line (fold) is formed substantially parallel to the seam between the seam 7c and the side plate 4c in the outer flap 2c.

  FIG. 6 is a diagram for explaining the method of opening the box. In the second embodiment, by cutting out the zipper 5c, the outer flap 1c on which the zipper 5c is formed includes a portion including the portion where the craft adhesive tape 6c is affixed in the outer flap 1c and other portions. And separated. FIG. 6 shows that the outer flap 1c after the zipper 5c is cut off is lifted upward with the seam 7c as a rotation axis, and includes the outer flap 1c. It shows that the craft adhesive tape 6c facing the gap between the end face plate 3c is cut and that there is a part of the outer flap 2c under the raised outer flap 1c.

Next, operations and effects in the second embodiment will be described with reference to FIGS. The zipper 5c of the developed box shown in FIG. 5 is cut out, and the craft adhesive tape 6c facing the gap between the outer flap 1c and the end face plate 3c is cut in the same manner as in the first embodiment. Next, in the process of lifting and rotating the remaining outer flap 2c from the edge on the side of the joint 7c with the fold line (fold) formed in the outer flap 2c as the rotation axis, the fold line (fold) of the outer flap 2c is turned. In addition to the lever principle as a fulcrum, the tearing force concentrates on the lifting side in the adhesive tape 6c, so that the portion between the outer flap 2c and the end face plate 3c remaining in the craft adhesive tape 6c with a light force can be removed. Can be cut and opened the box.
As described above, the cardboard box according to the second embodiment is opened using the lever principle not only for the outer flap 1c but also for the adhesive tape facing the gap between the outer flap 2c and the end face plate 3c. Therefore, the box can be easily opened with a weaker force than in the first embodiment.
