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 box. 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, as a measure against global warming associated with CO ₂ emissions in recent years, there is a movement to curb the use of plastics from the viewpoint of reducing the use of fossil fuels and curbing marine pollution such as microplastics. On the other hand, a sheet storage box (so-called filmless carton) that does not use a resin film is known (see, for example, Japanese Patent No. 6554284).

An object of the present invention is to provide a seat storage box that places less burden on fingers during use.

The sheet storage box according to the first aspect has a box body for accommodating a plurality of stacked sheets and a first opening formed on the top surface of the box body for taking out the sheets. The first opening has a given length in the first direction and a given width in the second direction intersecting the first direction, and at least a portion of the periphery of the first opening is corrugated. ..

In the present specification, the box body is a container in which a sheet is housed. The top surface of the box indicates the surface on which the contained sheet is taken out of the box. The first direction indicates a direction along a predetermined direction on the top surface of the box body. The second direction intersecting with the first direction indicates a direction orthogonal to a direction along a predetermined one direction on the top surface of the box or a direction along a direction intersecting the brace.

Further, the first opening for taking out the sheet constitutes an outlet for the sheet formed on the top surface of the box body. The peripheral edge of the first opening corresponds to the inner edge of the top surface forming the first opening on the top surface. The waveform means a shape in which concave portions and convex portions of a curve are repeatedly continuous. The fact that at least a part of the peripheral edge of the first opening is corrugated means that all or part of the peripheral edge of the first opening is composed of a waveform.

In the first aspect, by making at least a part of the peripheral edge of the first opening formed on the top surface of the box corrugated, the portion of the peripheral edge of the first opening touched by the fingers becomes only the convex portion of the corrugated portion. There is less strain on the fingers when using the seat storage box. Further, the portion where the sheet on the peripheral edge of the first opening rubs is only the corrugated convex portion, and the sheet is less likely to be damaged when the sheet is taken out. Further, the sheet to be taken out is easily supported by the convex portion of the wavy line formed on the peripheral edge of the first opening, and the sheet is suppressed from falling.

In the seat storage box according to the second aspect, the period of the waveform at both ends of the first opening in the first direction is longer than the period of the waveform at the center of the first opening in the first direction. .. The period of the waveform indicates the distance between two adjacent convex portions or the distance between the concave portions of the waveform. The fact that the period of the waveform at both ends of the first opening in the first direction is longer than the period of the waveform at the center of the first direction of the first opening means that the period of the waveform at the peripheral edge of the first opening is that of the first direction of the first opening. It is shown that the period of the waveform in the central portion is shorter than the period of the waveforms at both ends in the first direction.

The sheet taken out from the first opening is more likely to be rubbed at both ends in the first direction than the central portion in the first direction in the peripheral edge of the first opening. Therefore, in the second aspect, by making the period of the waveform at both ends of the first opening in the first direction longer than the period of the waveform at the center of the first opening in the first direction, both ends of the first direction are formed. In, the convex portion of the waveform can be reduced. As a result, the rubbing of the sheet at the peripheral edge of the first opening is alleviated, and the breakage of the sheet is suppressed.

Further, when taking out the sheet housed in the box body, the fingers are easily inserted in the vicinity of the central portion in the first direction of the first opening. On the other hand, in the second aspect, the period of the waveform in the central portion in the first direction at the peripheral edge of the first opening is shorter than the period of the waveform in both ends in the first direction of the first opening. Thereby, in the second aspect, when the finger is inserted into the central portion of the first opening, the burden on the finger can be reduced while reducing the discomfort when the finger touches the peripheral edge of the first opening. can.

In the seat storage box according to the third aspect, the width of the first opening widens from the central portion side of the first opening in the first direction toward both end portions in the first direction. Here, widening from the central portion side in the first direction of the first opening toward both end portions in the first direction means that the width of the first opening in the second direction is the width of the first opening along the first direction. It is shown that it expands in the second direction as it progresses from the central portion side of the first direction to both end portions sides of the first direction.

At the outlet of the sheet storage box, when the sheet is taken out, the sheet is easily clogged and broken at both ends in the longitudinal direction of the outlet. On the other hand, in the third aspect, the width of the first opening constituting the outlet is widened from the central portion side in the first direction of the first opening toward both end portions in the first direction. It becomes wider on both ends than on the center side in one direction. Therefore, when the sheet is taken out, the sheet is easily clogged and easily broken at both ends in the longitudinal direction of the outlet, so that the sheet is less likely to be clogged and breakage can be suppressed.

Further, in the third aspect, as described above, at the peripheral edge of the first opening, the period of the waveform at both ends of the first opening in the first direction is the period of the waveform at the center of the first opening in the first direction. Longer than. Therefore, in the third aspect, when the sheet is taken out, the portion where the sheet is rubbed at both ends of the peripheral edge of the first opening in the first direction is only the corrugated convex portion, and the damage of the sheet is further suppressed.

In the seat storage box according to the fourth aspect, at least a part of the peripheral edge of the first opening is curved at both ends. Here, bending at both ends means that the peripheral edge of the first opening is bent so as to be convex to the outside of the first opening at both ends of the first opening.

In the fourth aspect, at least a part of the peripheral edge of the first opening is curved at both ends of the first opening in the first direction, so that the sheet is pulled out at both ends of the outlet where the sheet is easily rubbed and broken. Can alleviate resistance to. Therefore, in the fourth aspect, the sheet is less likely to be clogged at the outlet, and the sheet can be prevented from breaking.

In the seat storage box according to the fifth aspect, the width of the first opening expands in the second direction at the central portion of the first opening in the first direction. Here, the fact that the width of the first opening in the second direction expands in the second direction at the central portion of the first opening in the first direction means that the width of the first opening in the central portion of the first direction in the second direction is the second. It shows that it is widened along two directions.

In the fifth aspect, by expanding in the second direction at the central portion of the first opening in the first direction, it becomes easier to insert a finger or the like into the central portion of the opened outlet. As a result, the upper sheet (for example, the first sheet or the first set of sheets) that is easily clogged in the take-out port can be easily pulled out. In addition, the sheet that has fallen into the box during use can be easily taken out by putting a finger in the box. Further, when the finger is inserted into the first opening, the burden on the finger can be reduced while further reducing the discomfort when the finger touches the peripheral edge of the first opening.

In the seat storage box according to the sixth aspect, at least a part of the peripheral edge of the first opening is curved in the second direction at the central portion. Here, bending in the second direction at the central portion means that the peripheral edge of the first opening bends so as to be convex outward in the second direction at the central portion in the first direction.

In the sixth aspect, when at least a part of the peripheral edge of the first opening is curved in the second direction at the central portion of the first opening in the first direction, the finger is inserted into the central portion of the first opening. , The fingers can smoothly touch the peripheral edge of the first opening. Therefore, it is possible to further reduce the burden on the fingers while further reducing the discomfort of the fingers touching the peripheral edge of the first opening.

In the sheet storage box according to the seventh aspect, the first opening is formed on the top surface of the sheet storage box when the first opening is formed, and the cut of the first opening is the waveform.

In the present specification, the cut line for cleavage indicates a cut line 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. The waveform constituting the cut of the first cleavage line corresponds to the waveform constituting at least a part of the peripheral edge of the first opening formed on the top surface after the first cleavage line is cleaved.

In the seventh aspect, the cut of the first cleavage line formed on the top surface is a waveform, and the waveform constituting the cut of the first cleavage line constitutes at least a part of the peripheral edge of the first opening. Corresponds to the waveform to be used. Therefore, in the seventh aspect, the outlet of the sheet can be formed on the top surface of the box body by cleaving the first cleavage line formed on the top surface.

Further, in the seventh aspect, as described above, the width of the first opening in the second direction narrows in the second direction as it progresses from both ends to the center of the first opening along the first direction. If so, when the first cleavage line is cleaved to form the first opening, the first cleavage line is formed from both ends of the first opening having a wide width in the second direction toward the central portion having a narrow width. By cleaving the first cleavage line, the first cleavage line can be smoothly cleaved.

In the sheet storage box according to the eighth aspect, a second opening for opening the first cleavage line is formed in a part of the top surface surrounded by the first cleavage line. .. Here, a part of the top surface surrounded by the first cleavage line occupies a part less than half of the top surface, and when the first cleavage line is cleaved, a first opening is formed on the top surface. Indicates the part. The second opening for cleaving the first cleavage line constitutes a trigger for the second opening to cleave the first cleavage line.

In the eighth aspect, a fingertip is inserted into the second opening by forming a second opening for cleaving the first cleaving cut line in a part of the top surface surrounded by the first cleaving cut line. The inserted fingertip can be hung on a part of the top surface and pulled upward. As a result, the second opening acts as a trigger when the first cleavage line is cleaved, and the formation of the first opening by cleaving the first cleavage line formed on the top surface becomes easy.

In the seat storage box according to the ninth aspect, at least a part of the peripheral edge of the second opening is corrugated. The fact that at least a part of the peripheral edge of the second opening is corrugated means that all or part of the peripheral edge of the second opening is composed of a corrugated form.

In the ninth aspect, by making at least a part of the peripheral edge of the second opening corrugated, the portion of the peripheral edge of the second opening that the fingertip touches becomes only the convex portion of the waveform. Therefore, when the first opening is formed by cleaving the first cleavage line and the first opening is formed on the top surface, the fingertip may be inserted into the second opening, or the inserted fingertip may be hung on a part of the top surface and pulled upward. In some cases, the burden on the fingertips can be reduced.

In the seat storage box according to the tenth aspect, the period of the waveform in the second opening is shorter than the period of the waveform in the first opening. Here, the period of the waveform in the first opening includes both the period of the waveform in the central portion of the first opening in the first direction and the period of the waveform in both ends of the first opening in the first direction.

In the tenth aspect, the period of the waveform at the second opening is made shorter than the period of the waveform at the first opening, so that the first opening is formed on the top surface by cleaving the first cleavage line. When inserting the fingertip into the second opening, or when the inserted fingertip is hung on a part of the top surface and pulled upward, the feeling of discomfort when the fingertip touches the peripheral edge of the second opening is reduced, and the fingertip is applied to the fingertip. The burden can be reduced.

In the seat storage box according to the eleventh aspect, at least a part of the peripheral edge of the second opening is curved from the central portion side of the first opening in the first direction to both end portions in the first direction. Here, bending from the central portion side in the first direction of the first opening to both end portions in the first direction means that the peripheral edge of the second opening becomes convex toward the outside in the first direction of the first opening. Indicates that it will turn to.

In the eleventh aspect, at least a part of the peripheral edge of the second opening is curved from the central portion side in the first direction of the first opening to both end portions in the first direction, thereby inserting the fingertip into the second opening. In doing so, the fingertip can smoothly touch the peripheral edge of the second opening. Therefore, it is possible to further reduce the burden on the fingertip while further reducing the discomfort of the fingertip touching the peripheral edge of the second opening.

In the sheet storage box according to the twelfth aspect, the second opening cut line is formed in a part of the top surface when the second opening is formed, and the cut of the second opening cut line is the waveform. Is. Here, the waveform constituting the cut of the second cleavage line is a waveform constituting at least a part of the peripheral edge of the second opening formed on a part of the top surface after the second cleavage line is cleaved. handle.

In the twelfth aspect, the cut of the second cleavage line formed on a part of the top surface is a waveform, and the waveform constituting the cut of the second cleavage line is at least one of the peripheral edges of the second opening. Corresponds to the waveforms that make up the part. Therefore, in the twelfth aspect, the sheet take-out port can be formed on a part of the top surface of the box body by cleaving the second cleavage line formed on the top surface.

In the seat storage box according to the thirteenth aspect, the second opening is formed on both ends of a part of the top surface in the first direction. Here, both ends of a part of the top surface in the first direction are both ends of the first opening formed on the top surface when the first cleavage line is cleaved in a part of the top surface. Corresponds to.

In the thirteenth aspect, a fingertip is inserted into a second opening formed on both ends of the first opening of a part of the top surface in the first direction, and the inserted fingertip is hung on a part of the top surface to be upward. Can be raised to. As a result, the first cleavage line can be cleaved from both ends of the first opening in the first direction toward the center, so that the first opening can be easily formed on the top surface.

Further, in the thirteenth aspect, as described above, the width of the first opening in the second direction narrows in the second direction as it progresses from both ends of the first opening toward the center along the first direction. If so, when the first cleavage line is cleaved to form the first opening, the first cleavage line is formed from both ends of the first opening having a wide width in the second direction toward the central portion having a narrow width. By cleaving the first cleavage line, the first cleavage line can be smoothly cleaved.

In the seat storage box according to the fourteenth aspect, the period of the waveform is 0.1 mm or more and 6 mm or less. Here, the period of the waveform includes both the period of the waveform at the peripheral edge of the first opening and the period of the waveform at the peripheral edge of the second opening. When the period of the waveform is 0.1 mm or more and 6 mm or less, it indicates that the scale of the waveform is minute.

In the fourteenth aspect, by setting the period of the waveform to 0.1 mm or more and 6 mm or less, the distance between the convex portions or the concave portions of the waveform is reduced. This makes it possible to further reduce the discomfort of the finger touching the peripheral edge of the first opening or the finger touching the second opening, and further reduce the burden on the finger or fingertip.

Further, in the fourteenth aspect, the peripheral edge of the first opening or the peripheral edge of the second opening is made corrugated by reducing the distance between the convex portions or the concave portions of the waveform at the peripheral edge of the first opening or the peripheral edge of the second opening. It is possible to suppress the deterioration of the appearance (or appearance) of the sheet storage box due to the above.

In the seat storage box according to the fifteenth aspect, the period of the waveform is twice or more the wave height of the waveform. Here, the wave height of the waveform indicates the vertical distance from the top of the convex portion of the waveform to the bottom of the concave portion.

In the fifteenth 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 first opening or the peripheral edge of the second opening becomes gentle. As a result, the peripheral edge of the first opening or the peripheral edge of the second opening becomes smooth, and the discomfort of the finger touching the peripheral edge of the first opening or the fingertip touching the peripheral edge of the second opening is further reduced, and the fingertip or the fingertip is touched. The burden can be further reduced.

Further, in the fifteenth aspect, the slope of the convex portion of the waveform formed on the peripheral edge of the first opening or the peripheral edge of the second opening becomes gentle, so that the peripheral edge of the first opening or the peripheral edge of the second opening becomes a waveform. It is possible to suppress the deterioration of the appearance (or appearance) of the sheet storage box due to this.

Both ends 40 and 50 were configured with a waveform U12 (period of about 2 mm, wave height of about 1 mm) (FIGS. 2, FIG. 3, and FIG. 4). Of the peripheral edge E2 of the first opening 20, the portion formed by the waveform U11 in the central portion 30 of the first opening 20 is curved in the second direction (Y direction), and is composed of the waveform U12 at both ends 40 and 50. The part was curved. The peripheral edges E3 of the second openings 60 and 70 are composed of a waveform U2 (period of about 1 mm, wave height of about 1 mm) (FIGS. 2 and 5). The peripheral edges E3 (portion formed by the waveform U2) of the second openings 60 and 70 are both end portions 40 in the first direction (X direction) from the central portion 30 side in the first direction (X direction) of the first opening 20. It was curved to the 50 side. The obtained test specimens were evaluated for openability, take-out property, take-out resistance value, and drop-in property. The results are shown in Table 1.
