Description

  The present invention relates to a container and a paper product.

  Conventionally, paper containers are widely known as containers for containing tissue paper such as tissue paper. However, in recent years, the use of a container made of a flexible film has been increasing for reasons such as environmental considerations, low cost, and ease of carrying without being bulky.

  A flexible film container is disclosed, for example, in Patent Document 1. In the container (bag body) disclosed in Patent Document 1, a slit planned portion having a length of 30 to 70% with respect to the width of a predetermined thin paper sheet is formed on the surface by a perforation, and this sewing machine By splitting the eyes, the slit planned portion is opened and becomes a slit portion. Patent Document 1 describes that since the thin paper is pulled out while the width of the thin paper is reduced at the slit portion, the next thin paper can be easily pulled out.

JP 2008-183034 A

  However, since the container made of a flexible film is lightweight, in the configuration disclosed in Patent Document 1, when there is a small amount of thin paper to be stored and the overall weight becomes small, the thin paper is used. When the container is pulled out, the container is pulled along with the tissue paper and is easily lifted. In that case, it is inconvenient because the tissue can not be pulled out unless the container is held down.

  On the other hand, if the length of the outlet is adjusted in consideration of the floating of the container, the effect that the next thin paper sheet is likely to be pulled out is reduced, and the next thin paper tends to fall into the inside of the housing.

  As described above, in the conventional flexible film container, it is difficult to simultaneously reduce both the lifting of the container and the falling of the next thin paper.

  In view of the above points, an aspect of the present invention is a container that can reduce both the lifting of the container when pulling out the thin paper and the falling of the next thin paper pulled out in a pop-up manner into the inside of the housing. The task is to provide.

  According to a first aspect of the present invention, there is provided a flexible film container which accommodates a laminate of thin paper sheets and can pull out the thin paper sheet from the laminated body through a slit-like outlet. The upper surface has a score line forming the outlet, or a split line capable of forming the outlet by splitting, and at least one end of the outlet has a longitudinal direction of the outlet It has a flap that opens to the outside.

  According to the first aspect, the housing body is provided with a flap that opens at the lengthwise end of the outlet at at least one end of the outlet. Since the flap is made of a flexible film, when the thin paper is pulled out, it receives force from the thin paper, and is flexibly curved and lifted upward. The flaps can then move flexibly in accordance with the movement of the tissue. As a result, the thin paper is pulled out smoothly without being caught on the edge of the outlet at the end, so that the container can be prevented from being pulled up by the thin paper and floating upward. In addition, in a state where the thin paper is pulled out and the next thin paper pops up, the thin paper can not fall down by gravity because the flap can support the thin paper. As described above, according to this embodiment, it is possible to suppress the lifting of the container when pulling out the thin paper, and to reduce the falling of the next drawn thin paper.

  In a second aspect of the present invention, the maximum length of the flap in the longitudinal direction of the outlet is 1 to 15 mm.

  According to the second aspect, since the flap has a predetermined maximum length in the length direction of the outlet, the flap can have appropriate flexibility and appropriate rigidity. As a result, when pulling out the thin paper, the flap can be reliably lifted upward, and the effect of supporting the popped-up thin paper can be improved.

  In the third aspect, the maximum length of the flap in the direction orthogonal to the length direction of the outlet is 1 to 20 mm.

  According to the third aspect of the present invention, since the flap has a predetermined maximum length in the direction orthogonal to the length direction of the outlet, the flap has appropriate flexibility and appropriate rigidity. be able to. In addition, the contact area between the inner surface of the flap and the thin paper can be secured, and the effect of supporting the pop-up thin paper can be improved, while the contact area between the flap and the thin paper becomes excessively large to prevent the drawing of the thin paper. Can be prevented.

  In a fourth aspect of the invention, the flap is formed by the score line or is formed by cleaving a tear line, the score line or tear line for forming the flap Is connected to the score line or the tear line for forming the outlet, and the flap opens so that the length of the outlet extends.

  According to the fourth aspect, the flap is formed by the tearing of the score line or tear line connecting to the score line or tear line for forming the outlet, and the length of the outlet is elongated So that the width of the outlet is broadened at the end. Thereby, when pulling out the thin paper, the thin paper can be prevented from being folded and pinched at the end, so that the effect of reducing the floating of the container can be further enhanced. In addition, since it is difficult to peel off the next thin paper following the thin paper to be pulled out from the thin paper to be pulled out at the end of the outlet, the effect of reducing the falling of the thin paper into the container can be enhanced.

  In a fifth aspect of the present invention, the length of the outlet when the flap is opened is shorter than the length of the stack of thin paper sheets in the longitudinal direction of the outlet.

  According to the fifth aspect, since the length of the take-out port when the flap is opened is shorter than the length of the taken-out paper sheet, the paper sheet is drawn while being narrowed. In this case, at the end, the tissue can be curved and the curved surface can be in contact with the inner surface of the flap. Therefore, the thin paper is pulled out smoothly without being caught on the edge of the outlet, and the effect of preventing the floating of the container is enhanced.

  In the sixth aspect of the present invention, the shape of the top view of the flap is a polygon, a partial circle, or a partial ellipse.

  According to the sixth aspect, since the shape of the top view of the flap is a polygon, a partial circle, or a partial oval, the flap can have a predetermined spread. Thereby, the effect of the flap mentioned above can be improved.

  A seventh aspect of the present invention is a thin paper product comprising a container of any of the first to sixth aspects and a stack of thin paper.

  According to the seventh aspect, it is possible to provide a thin paper product having the same function and effect as any of the first to sixth aspects.

  According to one aspect of the present invention, it is possible to provide a container capable of reducing both the lifting of the container when pulling out the thin paper and the falling of the next thin paper that is popped out into the inside of the container. .

It is a figure after tearing off the tearing line of FIG. It is a schematic diagram of the II line | wire cross section of FIG. It is a schematic diagram which shows the state from which the thin paper was pulled out from the upper surface of the container. It is a figure which shows the modification of the shape of a flap. It is a perspective view of the conventional container. It is a perspective view of the container of comparative examples 2 and 5. It is an enlarged top view of the tear line of the container of FIG. 8A.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, unless otherwise specified, the same or corresponding components may be denoted by the same reference symbols and description thereof may be omitted.

  FIG. 1 shows a perspective view of a container 1 according to an embodiment of the present invention (a thin paper product 100 including the container 1 and a laminate of thin paper). The figure which expanded the tearing line 20 and was seen from the upper surface in FIG. 2 is shown.

  The container 1 according to the present embodiment is made of a flexible film, and in the illustrated embodiment is manufactured by so-called caramel packaging. However, the packaging format of the embodiment of the present invention is not limited to the caramel packaging, and the container 1 of this embodiment may be manufactured by pillow packaging or the like.

  As a flexible film used for the container 1, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA) General-purpose resin film generally used as a container of thin paper, such as polyamide (PA), can be used. As the material of the flexible film, polyethylene, polypropylene, polyethylene terephthalate and the like are preferable because they are flexible and excellent in handleability, high in sealability when heat sealed, low in price, etc., odorless, water resistant Polyethylene is preferable in that it is excellent in resistance and chemical resistance and can be mass-produced at low cost. As polyethylene, high density polyethylene, low density polyethylene, etc. can be used. In addition, polypropylene is preferable because it is robust, easy to be molded, has a good color upon printing, and can impart gloss. The flexible film may be a laminate film in which a plurality of films are laminated, or may be a film composed of a mixture of two or more of the above resins.

  The thickness of the flexible film is preferably 20 to 70 μm, and more preferably 25 to 60 μm. By setting the thickness of the flexible film to 20 μm or more, sufficient strength as a container can be secured. Further, by setting the thickness of the flexible film to 70 μm or less, the flexibility and lightness of the container can be secured, and the cost can be suppressed.

  A stack of thin paper sheets can be accommodated inside the container 1, and the stack 1 of thin paper sheets can be combined with the stack of thin paper sheets to form a thin paper product 100. The stack of paper sheets is configured such that the paper sheets are pulled out in a pop-up manner. For example, a thin paper sheet is folded in two so that the folding direction is alternated, and the edges of the folded surface are respectively inserted into the folded inner surface of the adjacent thin paper sheet, that is, inserted alternately It is stacked in a broken state. Then, when one set or a set of stacked sheets is taken out, the subsequent sheets will be partially ejected to the outside. The tissue sheet may be folded in three or four as long as it can be pulled out in a pop-up manner.

The contained tissue paper may be a hygienic tissue paper such as tissue paper, toilet paper, kitchen paper, paper hand towel, paper cloth towel, wiper and the like. The basis weight of one ply of thin paper is preferably 10 to 25 g / m ² , and the thickness of two plies of thin paper is preferably 130 to 250 μm. The basis weight is determined by the basis weight measurement method of JIS P 8124 (1998).

  In addition, the dimensions of the stack of thin paper are such that the length in the length direction (x direction) of the outlet is about 180 to 250 mm, and the length in the direction (y direction) perpendicular to the length direction of the outlet in top view The height (z direction) can be about 30 to 100 mm. Such stacks of tissue paper can be produced, for example, by means of a rotary or multistand interfolder.

  As shown in FIG. 1, the container 1 has a tear line 20 on the top surface 10. The split line 20 includes a straight central line 21 and end lines 22 formed at both ends of the central line 21 as shown in FIGS. The part lines 22 are formed in connection with each other. The center line 21 extends in the x direction in FIG. 1 in a top view, and is located at the center of the container when viewed in the y direction orthogonal to the x direction. In the illustrated form, the shape drawn by the end line 22 is part of a rectangle. In the illustrated embodiment, the end lines 22 are formed at both ends of the center line 21, but may be formed at one end of the center line 21. Further, in the illustrated embodiment, both end wires 22, 22 have a line-symmetrical shape, but both end wires 22, 22 may not be line-symmetrical and may have different shapes and sizes.

  The x-direction in the drawing corresponds to the width direction of the stack of thin paper sheets contained in the container 1. The x-direction is orthogonal to the direction of withdrawal of the paper from the laminate of paper and corresponds to the direction of extension of the end of the paper that is picked up when withdrawn. The y-direction corresponds to the depth direction of the stack of thin paper sheets contained in the container 1. In the present embodiment, the direction perpendicular to the xy plane is taken as the z direction. The z direction corresponds to the height direction of the stack of tissue paper. In the illustrated container 1, a laminate whose length in the width direction is longer than the length in the depth direction is accommodated.

  The container 1 as a whole has a substantially rectangular solid shape, and the length in the x direction is longer than the length in the y direction. However, the container 1 may have another three-dimensional shape depending on the shape of the stored paper and the laminated body of the paper. For example, the length in the x direction of the container 1 may be equal to the length in the y direction, or may be shorter than the length in the y direction.

  The tearing line 20 shown in FIGS. 1 and 2 is a line by which the user can form an outlet by tearing at the start of use. In the illustrated embodiment, the tear line 20 is formed by perforations, but it may be another linear weak portion or mark as long as the user can tear at the start of use. Further, in the illustrated embodiment, the center line 21 is a single line, but the center line 21 may be two lines extending substantially in parallel at a predetermined interval, in which case two lines are formed. Can be split to remove the part between the split lines.

  Instead of the tear line 20, a cut line may be formed on the upper surface 10. That is, the outlet may be formed in advance on the upper surface 10 by a cut. In that case, in order to prevent dirt etc. from getting into the interior of the container before the start of use or the tissue is stained, the entire paper product 100 comprising the laminate of the paper and the container 1 containing it is , Can be packaged in a package or the like.

  In the form of FIG. 2, the shape drawn by the end line 22 is a part of a quadrangle, specifically a rectangle, in a top view, but is not limited to this shape. For example, it may be a part of a square other than a rectangle such as a square or a trapezoid, a part of a polygon such as a triangle or a pentagon, or a part of a circle or an ellipse.

  FIG. 3 shows the state after the split line 20 shown in FIG. 2 has been split. As shown in FIG. 3, the slit-like outlet 25 is formed by cleaving the tear line 20. By tearing off the end line 22 of the tear line 20, an end slit 22A is formed, whereby a flap (end flap) 32 is formed at at least one end of the outlet 25. it can. The flap is a flat member having a predetermined area, which is partially integrated with the upper surface 10 and is movable so as to open and close a portion separated from the upper surface 10. The flaps are sometimes referred to as hinges.

The flap 32 has the maximum length L _fx in the length direction (x direction) of the outlet 25 and has the maximum length L _fy in the direction (y direction) orthogonal to the x direction. Further, in the illustrated embodiment, the central flaps 31 can be formed at the center of the outlet 25 by breaking the central line 21 and the end lines 22 formed at both ends thereof. The central flap 31 can also be curved and lifted in the same manner as the flap 32. Therefore, the central flap 31 can support popped-up tissue, prevent falling of the tissue, and hold the tissue vertically (sheet holding Contribute to improving performance). The length of the central slit 21A formed by cleavage of the central line 21 and L _c. In the present specification, the term "slit" includes one having a predetermined width, and also includes one having a width of 0 mm and in which the edges of the slit are in contact with each other.

  As described above, in the case where a cutting line is formed instead of the tear line 20, the flap 32 is already formed by the cutting line before the start of use. In that case, at least one of the end lines 22 may be a cut line instead of a tear line, with the center line 21 being a tear line such as a perforation. If the end line 22 is a tear line, force is applied to the end when tearing the tear line of the center line 21 so that it can not tear along the end line 22 and the flap is properly Although the end line 22 may be configured as a score line and the flaps may be formed in advance, the flaps can be reliably secured.

  FIG. 4 is a part of a cross-sectional view taken along the line I-I of FIG. 3, in which the flap 32 is lifted upward. As mentioned above, the container 1 is made of a flexible film, and the flap 32 is also made of a flexible film. Therefore, the flap 32 can be bent and deformed flexibly when it receives a force from the thin paper when pulling out the thin paper. As indicated by arrow U in FIG. 4, the flap 32 is configured to open outward in the longitudinal direction (x direction in the figure) of the elongated outlet 25.

Also, the flaps 32 open so that the length of the outlet 25 is extended. The length L _t of the outlet 25 extended by the opening of the flap 32 can be at most the sum of the length L _c of the central slit 21 A and the maximum length L _fx in the x direction of the flap 32. In the illustrated embodiment, flaps 32 having the same size and shape are respectively provided at both ends of the outlet 25, and each flap 32 is in the x direction at a position where the central slit 21A extends from the end slit 22A. Since it has the maximum length L _fx , the length L _t of the outlet 25 extended by opening the flap 32 is, in particular, the length L _c of the central slit 21 A and the x of both flaps 32, 32 It is the sum (L _fx + Lc + L _fx ) with the maximum length L _fx in the direction. If one of the flaps 32 in the form shown is absent (if one flap 32 is provided at one end of the outlet 25), the length L _{t of the} outlet 25 extended by opening the flap 32 Is the sum (L _c + L _fx ) of the length L _c of the central slit 21A and the maximum length L _fx of the flap 32 in the x direction.

  Moreover, after the cleavage of the cleavage line, as described above, the central flaps 31, 31 are also formed at the center of the outlet 25. Therefore, the range of the outlet 25 formed by breaking the split line 20 can be, for example, the area indicated by the dotted line 25a shown in FIG.

  Hereinafter, the function of the flap 32 will be described.

  FIG. 7 shows a conventional container 1 'in which a linear perforation is formed at the center of the upper surface. Further, FIG. 8A shows a container 1 ′ ′ in which short perforations are formed at both ends of a linear perforation at the center of the upper surface in a direction orthogonal to the perforations at the center. In these containers, the thin paper is pulled out in contact with the edge of the outlet, so that it is easy to catch on the edge of the outlet, especially at the end of the outlet, and the movement is restricted. Therefore, particularly when the number of thin paper sheets stored in the storage body is small, the storage body is easily lifted up with the thin paper sheets. When the container is lifted, it is necessary to hold the container with the hand opposite to the hand for pulling out the thin paper, which is disadvantageous.

  On the other hand, since the flap 32 which opens to the longitudinal direction outer side of the extraction port 25 is formed in the at least one edge part of the extraction port 25, such floating | lifting of a container can be prevented. FIG. 5 shows a state in which the container 1 (thin paper product 100) according to the present embodiment is used. FIG. 5 shows a state in which the thin paper sheet P is pulled upward. As shown in FIG. 5, when the thin paper sheet P is pulled out, the flap 32 receives a force from the thin paper sheet P and opens upward (arrow U), and at least a part of the inner surface of the flap 32 comes into contact with the thin paper sheet P. Then, when pulling out the thin paper P, the flaps 32 move flexibly according to the movement of the thin paper P, and the movement of the thin paper P is not impeded.

  Also, FIG. 5 shows a state in which the first tissue sheet is pulled out and the next tissue sheet P 'is popped up. At this time, at least a part of the inner surface of the flap 32 comes into contact with the thin paper P ′, and a frictional force is generated at a portion in contact with the thin paper P ′. The thin paper sheet P is pulled downward by gravity, but the flap 32 is applied to the end face and the contact surface of the flap 32 in contact with the thin paper sheet P ′ because a compressive force (force to pull downward (arrow D)) acts. It will have the function of a kind of stick, and the flap 32 can support the thin paper P '. For this reason, thin paper P 'becomes difficult to fall inside a container. In addition, since the flap 32 can support the thin paper P ′ with at least a part of its inner surface, it can also contribute to maintaining the state in which the thin paper P ′ is drawn vertically.

  Thus, by providing the flap 32, the container is prevented from rising when pulling out the thin paper, and after the thin paper is pulled out, the falling of the thin paper is prevented for the pop-up thin paper. be able to. Furthermore, it also enables holding the thin paper sheet P in a vertically drawn state.

  Also, in the conventional flexible film container 1 '(FIG. 7) etc., the outlet 25 is straight, and when pulling out the thin paper, the thin paper is often folded and pinched at the end. . Therefore, the container is likely to come up with the withdrawal of the thin paper.

  On the other hand, in the present embodiment, the opening 25 is expanded in the x direction and the y direction by opening the flap 32 (FIG. 3). As a result, the thin paper sheet is hardly pinched at the end and is pulled out smoothly, so that the floating of the container can be further reduced.

  Also, because the width of the end of the outlet 25 is widened by the flap 32, the subsequent tissue can easily follow the extracted tissue, so that the subsequent tissue does not fall off at the end of the outlet, You can surely pop up the paper. Thereby, the effect of reducing the falling of the thin paper into the container can also be enhanced.

  Furthermore, in the conventional container 1 '(FIG. 7) or the like in which the flaps are not formed, stress is easily applied to the end of the outlet, so that the film may be taken out one after another at the end of the outlet. It is stretched and deformed easily. Therefore, there is a tendency for the next paper sheet drop to occur more gradually. On the other hand, according to this embodiment having the outlet 25 having the flap 32 at the end, deformation of the end of the outlet is small. This can also contribute to the reduction of the subsequent paper drop.

The maximum length L _{fx of the} flap 32 in the length direction (x direction) of the outlet 25 (FIG. 3, the x direction length of the shape formed by the end slits 22A) is preferably 1 to 15 mm, It is more preferable that it is 2-10 mm. By setting it as the said range, the flap 32 can have moderate flexibility and moderate rigidity which can reduce both the raising of a container and the falling of a thin paper. For example, by setting the maximum value of the length L _{fx in} the x direction to 1 mm or more, the flap can be reliably lifted upward when pulling out the thin paper, and by setting it to 15 mm or less, the pop-up thin paper is supported Can improve the effect.

The maximum length L _fy (FIG. 3, the y-direction length of the shape formed by the end slit 22A) of the flap 32 in the direction (y-direction) orthogonal to the length direction (x-direction) of the outlet 25 is And 1 to 20 mm, and more preferably 2 to 15 mm. By setting it as the said range, the flap 32 can have moderate flexibility and moderate rigidity which can reduce both the raising of a container and the falling of a thin paper. Further, by setting the maximum value of the length L _{fy in} the y direction to 1 mm or more, the contact area between the inner surface of the flap 32 and the thin paper can be secured, and the effect of supporting the popped-up thin paper can be improved. Moreover, by setting it as 20 mm or less, it can prevent that a contact area with tissue paper becomes large too much, and obstructing extraction of paper tissue. In addition, it is possible to prevent that the width of the outlet 25 becomes excessively large and the falling of the thin paper is easily generated.

In addition, the value (L _fx / L _fy ) of the ratio of the maximum length L _fx in the x direction of the flap 32 to the maximum length L _fy in the y direction is preferably 0.3 to 3, and 0.7 to More preferably, it is 1.5. By setting it as the said range, the flap 32 can have moderate flexibility and moderate rigidity which can reduce both the raising of a container and the falling of a thin paper.

In addition, the length L _{t of} the outlet 25 when the flap 32 is opened, that is, the sum of the length L _c of the central slit and the maximum length L _fx in the x direction of the flap 32 (in the form of FIG. 3) L _fx + L _c + L _fx ) is preferably shorter than the length in the x direction of the laminate of thin paper.

In the illustrated embodiment, the shape of the flap 32 is rectangular, specifically rectangular in a top view, but the shape of the flap 32 is appropriately selected according to the material of the film to be used and the type of thin paper . The shape of the flap 32 is preferably such that the flap 32 has a maximum length L _fx in the x direction at the position where the slit 21A is connected to the end slit 22A, as shown in FIG.

The modification of the shape of the flap 32 is concretely shown in FIG. As shown in FIGS. 6 (a) to 6 (e) respectively, the flaps 32 can be semicircular, triangular, partially elliptical, trapezoidal, or inverted trapezoidal. As shown in FIGS. _6A to _6E , each flap 32 has a maximum length L _fx in the length direction (x direction) of the outlet 25, and is orthogonal to the x direction (y direction) Of maximum length L _fy . Thus, the flap 32 can be a square other than a rectangle such as a square, a polygon such as a triangle or a pentagon, a partial circle (including a semicircle), a partial ellipse (including a semielliptic), or the like. By setting it as the said shape, since the flap 32 can have predetermined | prescribed expansion, the above-mentioned function as a flap can be exhibited favorably. In addition, it is preferable in the said shape that the flap 32 is a semicircle, a triangle, and a quadrangle.

  The tear line of the container 1 can be, for example, a perforation formed by a sewing blade on the film portion to be the upper surface 10. Moreover, it is also possible to use a blade in which a portion corresponding to the end is a straight blade so that a cut line is formed at the end. Thus, the container 1 according to the present embodiment can be manufactured only by changing the shape and size of the blade conventionally used.

  Hereinafter, the embodiments of the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

  In the present Example, the container which accommodated the laminated body of thin paper was produced and evaluated. The evaluation items and the evaluation method of each evaluation item are as follows.

[Sheet down]
Tissue paper was used as a tissue product (The tissue products of Examples 1 to 4 and Comparative Examples 1 to 3 were prepared using Universal Paper Co., Ltd. "Hello Soft Pack Tissue", Examples 5 to 6 and Comparative Example Four to six thin paper products are prepared using Aeon Co., Ltd. "tissue paper without outer box". In addition, the tissue paper is 150 pairs (300 sheets) of one pair of two sheets, and each pair is folded in two and folded to form a stacked body taken out in a pop-up manner. A thin paper product containing a stack of thin paper in a container was placed on a flat mounting surface. The first set of tissue paper was pulled out about half from the outlet, and the center portion of the tip in the x direction was pinched with a bead clip ("Kuri 17" manufactured by KOKUYO CO., LTD.). Insert the hook of a push pull gauge (made by Imada Co., Ltd., model number: Z2-20) into one hole of the handle part of the eyeball clip, and hold the container at a constant speed for 0.4 to 0.6 seconds. The tissue paper was pulled out vertically to the top surface of the. This operation was performed for the entire set of housed tissue papers. At that time, the number of sets in which the pop-up did not continue and the subsequent tissue paper did not come out of the outlet but fell into the interior of the container was recorded as the number of sheet drop-in sets. The smaller the number of sheet dropouts, the less the drop is likely to occur.

[Capital float occurrence]
Each time when the above-mentioned tissue paper was pulled out, it was checked whether the container was pulled by the tissue paper and the container was lifted from the mounting surface. The number of tissue paper sets remaining in the container when the container was lifted was recorded as the number of remaining sets when the container floats. The smaller the number of remaining units, the less the occurrence of floating of the container.

[Sheet holding performance]
When taking out the above-mentioned tissue paper, when taking out one set of tissue paper, it was observed whether the next set of tissue paper was held vertically to the upper surface of the container. The 11th to 20th tissue papers were observed and recorded. The sheet holding performance was evaluated as follows.
A: The number of sets held vertically is 8 or more: The number of sets held vertically is 5 to 7 sets Δ: The number of sets held vertically is 3 to 4 sets x: The number of sets held vertically Less than 2 pairs

Example 1
As shown in FIGS. 1 and 2, a paper product comprising a container having on its upper surface a split line including a center line and end lines at both ends thereof and a laminate of paper sheets housed in the container was prepared. . The center line of the cleavage line extends in the x direction at the center in the y direction of the upper surface of the container as shown in FIG. The container was made of a polypropylene (PP) film (film thickness: 40 μm), and used was one in which the laminate was packaged in a caramel packaging format. The depth (length in y direction) of the container was about 205 mm, the width (length in x direction) was about 100 mm, and the height (length in z direction) was about 50 mm. The stack of thin paper sheets contained is a 150-sheet (300-sheet) stack of two-ply tissue paper in a pop-up type, and as a whole, the width (length in the x direction) is 205 mm, the depth The y-direction length was 100 mm, and the height (z-direction length) was 50 mm.

The cleavage line on the top surface was cleaved to form an outlet as shown in FIG. The central line was cleaved to form a central slit and the end line to form a flap.
