Description

The present invention relates to a seat storage box.

The sheet storage box has a structure in which a sheet such as tissue paper is stored in a box (also referred to as a carton) made of thick paper or the like and is pulled out from an outlet opening on the top surface of the carton. In the conventional sheet storage box, a resin film (so-called window-pasting film) is provided at the take-out port, and the sheet is pulled out through a slit formed in the film (for example, Patent No. 4142238). See publication).

In addition, from the viewpoint of reducing the use of fossil fuels and suppressing marine pollution such as microplastics as a measure against global warming due to CO ₂ emissions in recent years, a sheet storage box that does not use a resin film (so-called filmless carton). ) Is increasing (see, for example, Japanese Patent No. 6554284).

Japanese Patent No. 4142238 Japanese Patent No. 6554284

An object of the present invention is to provide a seat storage box in which an outlet can be easily formed.

The sheet storage box according to the first aspect is formed on a box body for accommodating a plurality of laminated sheets and a top surface of the box body, and when cleaved, an outlet for the sheet is formed on the top surface. It has a cleavage line and the cut of the cleavage line is a waveform.

In the present specification, the box body is a container in which a sheet is housed. The top surface of the box constitutes a surface from which the contained sheet is taken out of the box. The cut line for cleavage is a cut line such as a perforation in which cuts and ties (uncut portions between two cuts) are alternately arranged, and when the ties are broken, the cuts on both sides become continuous cuts. Cuts indicate the individual cuts that make up the cleavage line. The waveform shows a wavy line shape in which peaks and valleys forming a curved convex portion are repeatedly continuous.

In the conventional sheet storage box, when a window pasting film is provided, an elongated recess (guide groove) is provided in the top surface corresponding to the peripheral edge of the outlet, and a cut line for cleavage is formed in the recess. The cleavage line is cleaved along the depression, facilitating the formation of an outlet. On the other hand, in the case of a filmless carton, since there is no window-pasting film, if such a guide groove is provided, the base papers of the box bodies may overlap with each other when the sheet storage box is manufactured, and the base paper may be poorly fed.

Therefore, in the case of a filmless carton, such a guide groove cannot be provided, and there is a problem that the cleavage line is cleaved in an unexpected direction when the outlet is formed, and the periphery of the outlet is torn. On the other hand, in the first aspect, by making the cut of the cleavage cut line formed on the top surface of the box into a corrugated shape, the cleavage cut line is formed between the cuts of the cleavage cut line at the time of forming the outlet. Even if it is cleaved in an unexpected direction, the cleaved line is likely to be connected to the convex part of the waveform.

Thereby, in the first aspect, the cleavage line can be opened in the planned (regular) direction without providing a guiding recess or groove, so that the periphery of the outlet is less likely to be torn. Therefore, according to the first aspect, it is easy to form an outlet.

Further, in the first aspect, since the waveform of the cut of the cleavage line is left on the peripheral edge of the outlet after the cleavage line is cleaved, only the convex portion of the waveform is touched by the fingers on the peripheral edge of the outlet. Therefore, the burden on the fingers when taking out the sheet is small. Further, since the portion where the sheet is rubbed on the peripheral edge of the take-out port is only the corrugated convex portion, the sheet is less likely to be damaged when the sheet is taken out. Further, the sheet is supported by the corrugated convex portion formed on the peripheral edge of the take-out port, and the sheet is suppressed from falling.

In the sheet storage box according to the second aspect, the corrugated peaks or valleys are located at both ends of the cut. Here, the peak of the waveform indicates a portion of the waveform that curves so as to be convex to the outside of the outlet. Further, the valley of the waveform indicates a portion of the waveform that curves so as to be convex inward of the outlet. Positioned at the edge of the cut means that the top of the convex portion forming the peak or valley is located at the edge of the cut or near the edge of the cut.

In the second aspect, the corrugated peaks or valleys are located at both ends of the cut, even if the cleavage line is cleaved in an unexpected direction between the cuts of the cleavage cut line during the formation of the outlet. The convex portion of the waveform can be arranged at a position close to the cleaved line. This makes it easier for the cleavage line to tear in the planned direction and makes it more difficult to tear around the outlet. Therefore, according to the second aspect, the formation of the outlet becomes easier.

In the seat storage box according to the third aspect, the mountain is located at both ends of the cut. When an outlet is formed in a box by cleaving the cleavage line, the periphery of the outlet is often torn when the cleavage line is cleaved toward the outside of the peripheral edge of the outlet.

Therefore, in the third aspect, since the corrugated peaks are located at both ends of the cut of the cut line for cleavage, both ends of the cut are convex to the outside of the outlet, so that the peripheral edge of the outlet is formed from one end of the cut. The cleavage line of the cleavage cut line that has been torn to the outside of the cut is likely to be connected to the other end of the adjacent cut. This makes it easier for the cleavage line to tear in the planned direction, making it even more difficult to tear around the outlet. Therefore, according to the third aspect, the formation of the outlet becomes easier.

In the seat storage box according to the fourth aspect, both ends of the cut extend inside the outlet. Here, extending inward of the outlet means that both ends of each cut constituting the cleavage line extend toward the inside of the outlet. When an outlet is formed in the box body by cleaving the cleavage line, the periphery of the outlet is difficult to tear as long as the cleavage line is cleaved toward the inside of the peripheral edge of the outlet.

Therefore, in the fourth aspect, both ends of each cut constituting the cleavage cut line extend inward of the outlet, so that the cleavage cut line is easily cleaved inside the peripheral edge of the outlet, and the outlet can be opened. It becomes difficult to cleave on the outside of the periphery. Therefore, in the fourth aspect, the periphery of the outlet is more difficult to tear, and the formation of the outlet becomes easier.

In the sheet storage box according to the fifth aspect, the ratio of the period of the waveform to the tie spacing of the tear line is 0.3 or more and 4 or less. Here, the tie spacing corresponds to the shortest distance between adjacent cuts of the cleavage cut line. The period of the waveform indicates the distance between two adjacent peaks or valleys of the waveform. The ratio of the period of the waveform to the interval of the ties indicates the ratio of the period of the period of the waveform when the length of the interval of the ties is 1.

In the fifth aspect, the ratio of the period of the waveform to the tie spacing of the cleavage line is 0.3 or more and 4 or less, so that the cleavage line is formed between the cuts of the cleavage line at the time of forming the outlet. Even if the cleavage is in an unexpected direction, the cleavage line is likely to connect to the corrugated recess. As a result, in the fifth aspect, the cleavage line is easily cleaved in the planned direction, and the periphery of the outlet is further less likely to be torn.

In the seat storage box according to the sixth aspect, the cycle is longer than the interval of the ties. Here, the fact that the period of the waveform is longer than the interval of ties means that the ratio of the period of the waveform to the interval of ties is larger than 1. In the sixth aspect, by making the period of the waveform longer than the interval of the ties, the inclination of the concave portion of the waveform constituting the cut becomes gentle. Therefore, when the cleavage line between the cuts of the cleavage line is connected to the concave portion of the corrugation, the force for tearing the tie can be smoothly transmitted.

The seat storage box according to the seventh aspect has a period of 0.1 mm or more and 6 mm or less. Here, the fact that the period of the waveform is 0.1 mm or more and 6 mm or less indicates that the scale of the waveform is minute. In the seventh aspect, by setting the period of the waveform to 0.1 mm or more and 6 mm or less, the distance between peaks and peaks or the distance between valleys of the waveform becomes smaller. As a result, the discomfort of the fingers touching the peripheral edge of the outlet formed on the top surface is reduced, and the burden on the fingers is reduced.

Further, in the seventh aspect, since the scale of the waveform becomes minute, the waveform of the cut of the cut line for cleavage is left on the peripheral edge of the outlet (the peripheral edge of the outlet becomes a waveform), so that the sheet storage box It is possible to suppress deterioration of the appearance (or appearance).

In the seat storage box according to the eighth aspect, the period is twice or more the wave height of the waveform. Here, the wave height of the waveform indicates the vertical distance from the top BM of the peak B of the waveform to the top DM of the valley D.

In the eighth aspect, by making the period of the waveform more than twice the wave height of the waveform, the inclination of the convex portion of the waveform formed on the peripheral edge of the outlet after the cleavage line is cleaved becomes gentle. As a result, the peripheral edge of the outlet formed after the cleavage line is cleaved becomes smooth, and the sheet is less likely to be torn when the sheet is taken out from the outlet. In addition, the discomfort of the fingers touching the peripheral edge of the take-out port is further reduced, and the burden on the fingers is further reduced.

Further, in the eighth aspect, the slope of the convex portion of the corrugated portion formed on the peripheral edge of the outlet becomes gentle, so that the peripheral edge of the outlet becomes corrugated and the appearance (or appearance) of the sheet storage box deteriorates. Can be further suppressed.

According to one aspect of the present invention, it is possible to provide a seat storage box in which an outlet can be easily formed.

The fact that the period P of the waveform U is 0.1 mm or more and 6 mm or less indicates that the scale of the waveform U is minute.

In the seat storage box 100 according to the present embodiment, the period P of the waveform U is twice or more the wave height H of the waveform U. Here, the wave height H of the waveform U indicates a vertical distance H from the top BM of the peak B of the waveform U to the top DM of the valley D.

A part 11A of the top surface 11 occupies a part less than half of the top surface 11, and is a part where a first opening 20 is formed on the top surface 11 when the cleavage line M1 is cleaved (FIGS. 2, FIG. 2). 10). The second openings 30 and 40 constitute a trigger for the second openings 30 and 40 to cleave the cleavage line M1.

A part (a portion composed of a waveform) of the peripheral edges E3 of the second openings 30 and 40 is a portion 22 at both ends in the longitudinal direction (X direction) from the central portion 21 side in the longitudinal direction (X direction) of the first opening 20. It curves to the 23 side. Here, the peripheral edges E3 of the second openings 30 and 40 are curved from the central portion 21 side in the longitudinal direction (X direction) to the both end portions 22 and 23 in the longitudinal direction (X direction) of the first opening 20. It is shown that the first opening 20 bends convexly toward the outside in the longitudinal direction (X direction) (FIGS. 1 and 2).

In the present embodiment, a cleavage line M2 is formed in a part 11A of the top surface 11 so that the second openings 30 and 40 are formed when the opening is performed. Cut C2 and tie T2 (the uncut portion between the two cuts C2 and C2) are alternately arranged on the cleavage line M2, and when the tie T2 breaks, the adjacent cuts C2 and C2 become continuous cuts. ..

In the cleavage line M2, the length of each cut C2 can be 0.3 mm or more and 40 mm or less, preferably 0.5 mm or more and 35 mm or less, and more preferably 1 mm or more and 30 mm or less. The length of each tie T2 can be 0.3 mm or more and 2.5 mm or less, preferably 0.5 mm or more and 1.5 mm or less, and more preferably 0.8 mm or more and 1.2 mm or less. ..

In the present embodiment, the cut C2 of the cleavage line M2 is composed of a waveform (FIG. 2). The waveform constituting the cut C2 of the cleavage line M2 is not particularly limited, and for example, the same waveform as the above-mentioned waveform U can be adopted. In this embodiment, by making the cut C2 of the cleavage line M2 a waveform, the waveform of the cut C2 is left on the peripheral edges E3 of the second openings 30 and 40 when the cleavage line M2 is cleaved (the waveform of the cut C2 is left on the peripheral edges E3 of the second openings 30 and 40. FIG. 10).

In the conventional sheet storage box, when a window pasting film is provided, an elongated recess (guide groove) is provided in the top surface corresponding to the peripheral edge of the outlet, and a perforation or the like is cut in the recess. By forming the cleavage line, the cleavage line is cleaved along the recess, facilitating the formation of the outlet. On the other hand, in the case of a filmless carton, since there is no window-pasting film, if such a guide groove is provided, the base papers of the box bodies may overlap with each other when the sheet storage box is manufactured, and the base paper may be poorly fed. Therefore, in the case of a filmless carton, such a guide groove cannot be provided, and there is a problem that the cleavage line is cleaved in an unexpected direction UD when the outlet is formed, and the periphery of the outlet is torn. (Fig. 9).

Therefore, the sheet storage box 100 of the present embodiment is configured such that the peaks B or valleys D of the waveform U are located at both ends (ends CE) of the cut C1. When the outlet 20 is formed in the box body 10 by cleaving the cleavage line M1, the periphery of the outlet 20 when the cleavage line M1 is cleaved toward the outside of the peripheral edge E2 of the outlet 20. 11B often tears. Therefore, it is preferable that the mountain B is located at both ends (end CE) of the cut C1.

Here, the mountain B of the waveform U indicates a portion of the waveform U that is curved so as to be convex to the outside (outer region OA) of the outlet 20. Further, the valley D of the waveform U indicates a portion of the waveform U that is curved so as to be convex inward (inner region IA) of the outlet 20. To be located at the end CE of the cut C1 means that the top BM or the top DM of the convex portion constituting the peak B or the valley D is located at the end edge V1, V2 or the end edge V1, V2 of the cut C1. show.

When the outlet 20 is formed in the box body 10 by cleaving the cleavage line M1, the periphery of the outlet 20 as long as the cleavage line M1 is cleaved toward the inside of the peripheral edge E2 of the outlet 20. 11B is hard to tear.

Therefore, in the sheet storage box 100 according to the present embodiment, both ends (end CEs) of the cut C1 are configured to extend inside the outlet 20 (inner region IA). Here, extending to the inside of the outlet 20 (inner region IA) means that both ends (end CE) of each cut C1 constituting the cleavage line M1 are directed toward the inside of the outlet 20 (inner region IA). (Fig. 6).

In the sheet storage box 100 according to the embodiment, the ratio of the period P of the waveform U to the interval Q of the tie T1 of the cleavage line M1 is 0.3 or more and 4 or less. Here, the interval Q of the tie T1 corresponds to the shortest distance Q between adjacent cuts C1 of the cleavage line M1 (FIG. 6). The ratio of the period P of the waveform U to the interval Q of the tie T1 indicates the ratio of the length of the period P of the waveform U when the length of the interval Q of the tie T1 is 1.

In the seat storage box 100 according to the present embodiment, the period P is longer than the interval Q of the tie T1. The fact that the period P of the waveform U is longer than the interval Q of the ties T1 indicates that the ratio of the period P of the waveform U to the interval Q of the ties T1 is larger than 1.

Hereinafter, the effects of this embodiment will be described. In the conventional sheet storage box, as shown in FIG. 9, when the cleavage line M1 is cleaved in an unexpected direction UD between the cuts C1 of the cleavage line M1 at the time of forming the take-out port 20, the cleave line is cleaved. The CB is continuous with one end V2 of one cut C1 at one end V3, but a gap G is generated between the CB and the other cut C1 at the other end V4. Therefore, in the conventional sheet storage box, the cleavage line M1 cannot be torn in the planned (regular) direction RD, and the peripheral 11B of the outlet 20 is easily torn.

On the other hand, in the present embodiment, as described above, the cut C1 of the cleavage line M1 formed on the top surface 11 of the box body 10 is formed into a waveform U, so that the cut C1 can be used for cleavage when the outlet 20 is formed. Even when the cleavage line M1 is cleaved in an unexpected direction UD between the cuts C1 of the cut line M1, the cleaved cleavage line CA is likely to be connected to the convex portion (peak B or valley D) of the waveform U.

As a result, in the present embodiment, the cleavage cut line M1 can be cleaved in the planned (regular) direction RD without providing a guiding recess or groove, so that the peripheral 11B of the outlet 20 is less likely to be torn. (Figs. 6 to 8). Therefore, according to the present embodiment, it is easy to form the outlet 20.

Further, in the present embodiment, as described above, the waveform U of the cut C1 of the cleavage line M1 is left on the peripheral edge E2 of the outlet 20 after the cleavage line M1 is cleaved. Therefore, the portion of the peripheral edge E2 of the take-out port 20 that the finger touches is only the convex portion (valley D) of the waveform U, and the burden on the finger when the sheet S is taken out (for example, the finger or the like is hurt or hurt). There are few (Fig. 11).

Further, in the present embodiment, as described above, since the portion where the sheet S of the peripheral edge E2 of the outlet 20 rubs is only the convex portion (valley D) of the waveform U, the sheet S is less likely to be damaged when the sheet S is taken out. .. Further, the sheet S (sheet S1) is supported by the convex portion (valley D) of the corrugation formed on the peripheral edge E2 of the take-out port 20, and the depression of the sheet S is suppressed (FIG. 12).

In the present embodiment, as described above, the peaks B or valleys D of the waveform U are located at both ends (ends CE) of the cut C1, so that between the cuts C1 of the cut line M1 for cleavage when the outlet 20 is formed. Even when the cleavage line M1 is cleaved in an unexpected direction UD, the concave portion (mountain B) of the waveform U can be arranged at a position close to the cleaved tear line CA. As a result, the cleavage line M1 is more likely to be cleaved in the planned direction RD, and the periphery 11B of the outlet 20 is less likely to be torn (FIGS. 6 to 8).

In the present embodiment, as described above, the peak B of the waveform U is located at both ends (end CE) of the cut C1 of the cut line M1 for cleavage, so that both ends (end CE) of the cut C1 are taken. Since it is convex to the outside of the outlet 20 (outer region OA), the cleavage line CA of the cleavage line M1 that is cleavaged from one end of the cut C1 to the outside of the peripheral edge E2 of the outlet 20 is connected to the other end of the adjacent cut C1. Cheap. As a result, the cleavage line M1 is easily cleaved in the planned direction RD, and the peripheral 11B of the outlet 20 is more difficult to tear (FIGS. 2, FIGS. 6 to 8, 11).

In the present embodiment, as described above, both ends (end CEs) of the cuts C1 constituting the cleavage line M1 extend inside the outlet 20 (inner region IA), whereby the cleavage line M1 Is likely to be cleaved inside the peripheral edge E2 of the outlet 20, and is less likely to be cleaved outside the peripheral edge E2 of the outlet 20. Therefore, in the present embodiment, the periphery 11B of the outlet 20 is more difficult to tear (FIGS. 2, FIGS. 6 to 8, 11).

In the present embodiment, as described above, the ratio of the period P of the waveform U to the interval Q of the tie T1 of the cleavage line M1 is set to 0.3 or more and 4 or less, so that the cleavage cut is formed when the outlet 20 is formed. Even when the cleavage line M1 is cleaved in an unexpected direction UD between the cuts C1 of the line of sight M1, the cleavage line CA is likely to be connected to the concave portion (mountain B) of the waveform U (FIGS. 6 to 8). As a result, in the present embodiment, the cleavage line M1 is easily cleaved in the planned direction RD, and the peripheral 11B of the outlet 20 is further less likely to be cleaved.

In the present embodiment, as described above, by making the period P of the waveform U longer than the interval Q of the ties T1, the inclination of the concave portion (mountain B) of the waveform U constituting the cut C1 becomes gentle (FIGS. 3 to 3). FIG. 5). Therefore, when the cleavage line CA between the cuts C1 of the cleavage line M1 is connected to the concave portion (mountain B) of the waveform U, the force for cleaving the tie T1 can be smoothly transmitted (FIGS. 6 to 8).

In the present embodiment, as described above, by setting the period P of the waveform U to 0.1 mm or more and 6 mm or less, the interval Q between the peaks B1 and B2 of the waveform U or the interval Q between the valleys D1 and D2 becomes smaller. (FIGS. 3 to 5). As a result, the discomfort of the fingers touching the peripheral edge E2 of the outlet 20 formed on the top surface 11 is reduced, and the burden on the fingers is reduced (FIG. 11).

Further, in the present embodiment, since the scale of the waveform U becomes minute, the waveform U of the cut C1 of the cleavage line M1 is left on the peripheral edge E2 of the outlet 20 (the peripheral edge E2 of the outlet 20 becomes the waveform U). It is possible to suppress the deterioration of the appearance (or appearance) of the sheet storage box 100 due to (FIGS. 3 to 5 and 11).

In the present embodiment, as described above, by setting the period P of the waveform U to be twice or more the wave height H of the waveform U, the cleavage line M1 is formed on the peripheral edge E2 of the outlet 20 after cleavage. The inclination of the concave portion or the convex portion (peak B or valley D) of the waveform U becomes gentle (FIGS. 3 to 5). As a result, the peripheral edge E2 of the outlet 20 formed after the cleavage line M1 is cleaved becomes smooth, and the sheet S (sheet S1) is less likely to be torn when the sheet S (sheet S1) is taken out from the outlet 20. (Fig. 12). Further, the discomfort of the fingers touching the peripheral edge E2 of the take-out port 20 is further reduced, and the burden on the fingers is further reduced.

Further, in the present embodiment, the peripheral edge E2 of the outlet 20 becomes corrugated by making the slope of the concave or convex portion (mountain B or valley D) of the waveform formed on the peripheral edge E2 of the outlet 20 gentle. It is possible to further suppress the deterioration of the appearance (or appearance) of the sheet storage box 100 due to the above (FIGS. 3 to 5 and 11).

At the outlet of the sheet storage box, as described above, when the sheet S is taken out, the sheets are easily clogged and broken at both ends in the longitudinal direction (X direction) of the outlet. On the other hand, in the present embodiment, the outlet is widened from the central portion 21 side in the longitudinal direction (X direction) of the first opening 20 toward both end portions 22 and 23 in the longitudinal direction (X direction). The width W2 of the (first opening) 20 is wider on both end portions 22 and 23 than on the central portion 21 side in the longitudinal direction (X direction). Therefore, when the sheet S is taken out, the sheet S is less likely to be clogged at both ends in the longitudinal direction of the outlet 20 which is easily clogged and easily broken, and the sheet S can be suppressed from being broken (FIGS. 1, FIG. 2, and FIG. 11). , FIG. 12).

In the present embodiment, as described above, the peripheral edge E2 of the first opening 20 is curved at both ends 22 and 23 in the longitudinal direction (X direction) of the first opening 20, so that the sheet S is easily rubbed and easily broken. At both ends 22, 23 of the outlet (first opening) 20, the resistance to the drawn sheet S can be relieved. Therefore, in the present embodiment, the sheet S is less likely to be clogged at the outlet (first opening) 20, and breakage of the sheet S can be suppressed.

In the present embodiment, as described above, the central portion 21 of the first opening 20 in the longitudinal direction (X direction) expands in the lateral direction (Y direction), so that the center of the opened outlet (first opening) 20 is formed. It becomes easier to put fingers and the like in the portion 21. As a result, the upper sheet S (for example, the first sheet or the first set of sheets S1) that is easily clogged in the take-out port (first opening) 20 can be easily pulled out. In addition, the sheet S that has fallen into the box body 10 during use can be easily taken out by inserting a finger into the box body 10. Further, when the finger is inserted into the first opening 20, the discomfort when the finger touches the peripheral edge E2 of the first opening 20 can be further reduced, and the burden on the finger can be further reduced (FIGS. 1 and 1). 2, FIG. 11, FIG. 12).

In the present embodiment, as described above, the peripheral edge E2 of the first opening 20 is curved in the lateral direction (Y direction) at the central portion 21 of the longitudinal direction (X direction) of the first opening 20 to hold the fingers. When inserting into the central portion 21 of the first opening 20, the fingers can smoothly touch the peripheral edge E2 of the first opening 20. Therefore, it is possible to further reduce the discomfort of the fingers touching the peripheral edge E2 of the first opening 20, and further reduce the burden on the fingers.

In the present embodiment, as described above, the cut C1 of the cleavage line M1 formed on the top surface 11 is the waveform U, and when the cleavage line M1 is cleaved, the waveform U of the cut C1 is the outlet 20. It is left on the peripheral edge E2 of. Therefore, in the present embodiment, by cleaving the cleavage line M1 formed on the top surface 11, the outlet (first opening) of the sheet S whose peripheral edge E2 becomes a waveform U on the top surface 11 of the box body 10). 20 can be formed (FIGS. 1-12).

Further, in the present embodiment, as described above, the width W2 of the first opening 20 in the lateral direction (Y direction) is from both ends 22 and 23 of the first opening 20 along the longitudinal direction (X direction). It narrows in the lateral direction (Y direction) toward the central portion 21 side. Therefore, when the cleavage line M1 is cleaved to form the first opening 20, the width W2 in the lateral direction (Y direction) is wide, and the width W2 is narrow from both ends 22 and 23 of the first opening 20. By cleaving the cleavage line M1 toward 21, the cleavage line M1 can be smoothly cleaved (FIGS. 1, FIG. 2, FIGS. 10 to 12).

In the present embodiment, as described above, the second openings 30 and 40 for cleaving the cleaving cut line M1 are formed on a part 11A of the top surface 11 surrounded by the cleaving cut line M1. A fingertip can be inserted into the second openings 30 and 40, and the inserted fingertip can be hung on a part 11A of the top surface 11 and pulled upward. As a result, the second openings 30 and 40 act as a trigger when the cleaving cut line M1 is cleaved, and the formation of the first opening 20 by cleaving the cleaving cut line M1 formed on the top surface 11 becomes easy. (FIG. 1, FIG. 2, FIG. 10, FIG. 11).

In the present embodiment, as described above, by making the cut C2 of the cleavage line M2 constituting the second openings 30 and 40 corrugated, the portion touched by the fingertips of the peripheral edges E3 of the second openings 30 and 40 is corrugated. Only the convex part of U2. Therefore, when the cleft cut line M1 is cleaved to form the first opening 20 on the top surface 11, the fingertip is inserted into the second openings 30 and 40, or the inserted fingertip is partially 11A on the top surface 11. It is possible to reduce the burden on the fingers when the finger is hung and pulled upward (FIGS. 1 to 5 and 10).

In the present embodiment, as described above, a part of the peripheral edge E3 (the portion composed of the waveform) of the second openings 30 and 40 is longitudinal from the central portion 21 side in the longitudinal direction (X direction) of the first opening 20. By curving toward both ends 22 and 23 in the direction (X direction), the fingertip smoothly touches the peripheral edge E3 of the second openings 30 and 40 when the fingertip is inserted into the second openings 30 and 40. Can be done. Therefore, the discomfort of the fingertip touching the peripheral edge E3 of the second openings 30 and 40 can be further reduced, and the burden on the fingertip can be further reduced (FIGS. 1 to 5 and 10).

In the present embodiment, as described above, the cut C2 of the cleavage line M2 formed on the part 11A of the top surface 11 is a waveform, and the waveform of the cut C2 is the first when the cleavage line M2 is cleaved. 2 It is left on the peripheral edge E3 of the openings 30 and 40. Therefore, in the present embodiment, by cleaving the cleavage line M2 formed in the part 11A of the top surface 11, the peripheral edge E3 has a corrugated second opening 30 in the part 11A of the top surface 11 of the box body 10. , 40 can be formed (FIGS. 1-5, 10).

The second openings 30 and 40 thus formed in the part 11A of the top surface 11 can form a trigger for cleaving the cleavage line M1 as described above. Specifically, by cleaving the cleavage line M2, a fragment F connected to a part 11A of the top surface 11 via the base end R is formed, and the fragment F is tilted inward or outward of the box body 10. As a result, the second openings 30 and 40 are formed. Then, by inserting the fingertip into the second openings 30 and 40, the fingertip can be hung on a part 11A of the top surface 11. Further, since the fingertips inserted into the second openings 30 and 40 are hung on the base end R of the fragment F to be a crease, the burden on the fingertips is further reduced (FIG. 10).

In the present embodiment, as described above, the fingertips are inserted into the second openings 30 and 40 formed on both ends 22 and 23 in the longitudinal direction (X direction) of the first opening 20 of a part 11A of the top surface 11. Then, the inserted fingertip can be hung on a part 11A of the top surface 11 and pulled upward. As a result, the cleavage cut line M1 can be cleaved from both end portions 22 and 23 in the longitudinal direction (X direction) of the first opening 20 toward the central portion 21, so that the first opening 20 to the top surface 11 can be cleaved. It is easy to form (FIG. 1, FIG. 2, FIG. 10, FIG. 11).
