Description

The present invention relates to an enclosure and a tissue paper product.

Conventionally, paper is widely known as an accommodating body for accommodating thin paper such as tissue paper. However, in recent years, the use of flexible film containers has been increasing due to environmental considerations, low price, and easy portability without being bulky.

The flexible film enclosure is disclosed, for example, in Patent Document 1. In the housing (bag body) disclosed in Patent Document 1, a slit scheduled portion having a length of 30 to 70% with respect to the width of a predetermined thin paper is formed on the surface by perforations. By dehiscence of the eyes, the planned slit 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 in the slit portion, the next thin paper can be easily pulled out.

Japanese Unexamined Patent Publication No. 2008-183034

However, since the accommodation body made of a flexible film is lightweight, in the configuration disclosed in Patent Document 1, when the amount of thin paper contained is reduced and the overall weight is reduced, the thin paper is used. When pulled out, the container is pulled together with the tissue paper, making it easier to lift. In that case, it may not be possible to pull out the thin paper unless the container is pressed, which is inconvenient.

On the other hand, if the length of the outlet is adjusted to be longer in consideration of the floating of the container, the effect that the next thin paper is easily pulled out is reduced, and the next thin paper is easily dropped into the inside of the container.

As described above, in the conventional flexible film accommodating body, it is difficult to reduce both the floating of the accommodating body and the drop of the next thin paper at the same time.

In view of the above points, one embodiment of the present invention provides an accommodating body capable of reducing both the floating of the container when the thin paper is pulled out and the next thin paper being pulled out in a pop-up manner falling into the inside of the container. The challenge is to provide.

The first aspect of the present invention is an accommodating body made of a flexible film capable of accommodating a laminated body of thin paper and pulling out the thin paper from the laminated body in a pop-up manner through a slit-shaped outlet. The upper surface has a notch line forming the outlet or a dehiscence line capable of forming the outlet by dehiscence, and at least one end of the outlet is in the length direction of the outlet. It has a flap that opens outward.

According to the first aspect, the enclosure is provided with a flap at at least one end of the outlet that opens outward in the length direction of the outlet. Since the flap is made of a flexible film, when the tissue paper is pulled out, it receives a force from the tissue paper and is flexibly curved and lifted upward. The flap can move flexibly according to the movement of the tissue paper. As a result, the tissue paper is smoothly pulled out without being caught by the edge of the outlet at the end portion, so that it is possible to reduce the inclusion from being pulled by the tissue paper and floating upward. In addition, when the tissue paper is pulled out and the next tissue paper pops up, the flap can support the tissue paper, so that the tissue paper is less likely to fall downward due to gravity. As described above, according to this embodiment, it is possible to suppress the floating of the container when the thin paper is pulled out and to reduce the drop of the next thin paper to be pulled out.

In the second aspect of the present invention, the maximum length of the flap in the length 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 the thin paper is pulled out, the flap is surely lifted upward, and the effect of supporting the pop-up tissue paper can be improved.

In the third embodiment, 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 tissue paper can be secured to improve the effect of supporting the popped tissue paper, while the contact area between the flap and the tissue paper becomes excessively large to prevent the tissue paper from being pulled out. Can be prevented.

In a fourth aspect of the invention, the flap is formed by the cut line or is formed by dehiscence of the dehiscence line, and the cut line or dehiscence line for forming the flap. Is connected to the cut line or the dehiscence line for forming the outlet, and the flap is opened so that the length of the outlet is extended.

According to the fourth aspect, the flap is formed by dehiscence of the cut line or dehiscence line connected to the cut line or dehiscence line for forming the outlet, and the length of the outlet is extended. As it opens so as to, the width of the outlet is widened at the end. As a result, when the thin paper is pulled out, it is possible to prevent the thin paper from being folded and pinched at the end portion, so that the effect of reducing the floating of the container is further enhanced. Further, since the next thin paper following the drawn thin paper is less likely to be peeled off from the drawn thin paper at the end of the outlet, the effect of reducing the drop of the thin paper into the container can be enhanced.

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

According to the fifth aspect, since the length of the outlet when the flap is opened is shorter than the length of the tissue paper to be taken out, the tissue paper is pulled out while being reduced in width. At this time, the tissue paper is curved at the end portion, and the curved surface can come into contact with the inner surface of the flap. Therefore, the thin paper is smoothly pulled out without being caught on the edge of the take-out port, and the effect of preventing the housing from rising is enhanced.

In the sixth aspect of the present invention, the top view shape of the flap is polygonal, partially circular, or partially elliptical.

According to the sixth aspect, since the shape of the flap in the top view is polygonal, partially circular, or partially elliptical, the flap can have a predetermined spread. Thereby, the effect of the flap described above can be improved.

A seventh aspect of the present invention is a tissue paper product comprising any of the inclusions of any of the first to sixth embodiments and a laminate of tissue paper.

According to the seventh embodiment, it is possible to provide a thin paper product having the same action and effect as any of the first to sixth embodiments.

According to one embodiment of the present invention, it is possible to provide an accommodation body capable of reducing both the floating of the housing when the thin paper is pulled out and the next thin paper being pulled out in a pop-up manner falling into the inside of the housing. ..

It is a figure after dehiscence of the dehiscence line of FIG. It is a schematic diagram of the II line cross section of FIG. It is a schematic diagram which shows the state which the thin paper is pulled out from the upper surface of the containment body. It is a figure which shows the deformation example of the shape of a flap. It is a perspective view of the conventional containment body. It is a perspective view of the containment body of Comparative Examples 2 and 5. FIG. 8 is an enlarged top view of the dehiscence line of the enclosure of FIG. 8A.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding configurations may be designated by the same reference numerals and description thereof may be omitted.

FIG. 1 shows a perspective view of an accommodating body 1 (a thin leaf paper product 100 including an accommodating body 1 and a laminated body of thin paper) according to one embodiment of the present invention. FIG. 2 shows an enlarged view of the dehiscence line 20 as viewed from above.

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

The flexible film used for the housing 1 includes polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), and ethylene-vinyl acetate copolymer (EVA). ), Polyethylene (PA) and the like, a general-purpose resin film generally used as an accommodating body for thin leaf paper can be used. As the material of the flexible film, polyethylene, polypropylene, polyethylene terephthalate, etc. are preferable, odorless, and water resistant because they are flexible and have excellent handleability, have high sealing properties when heat-sealed, and are inexpensive. Polyethylene is preferable because it has excellent properties and chemical resistance and can be mass-produced at low cost. As the polyethylene, high-density polyethylene, low-density polyethylene and the like can be used. In addition, polypropylene is preferable because it is robust, easy to mold, has good color development during printing, and can impart gloss. The flexible film may be a laminated 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, more preferably 25 to 60 μm. By setting the thickness of the flexible film to 20 μm or more, sufficient strength as an accommodating body can be ensured. Further, by setting the thickness of the flexible film to 70 μm or less, the flexibility and lightness of the housing can be ensured, and the cost can be suppressed.

A laminated thin paper can be accommodated inside the accommodating body 1, and the accommodating body 1 and the laminated thin paper can be combined to form a thin paper product 100. The thin paper laminate is configured so that the tissue is pulled out in a pop-up manner. For example, tissue paper is folded in half so that the folding directions are staggered, and the edges of the folded surface are inserted into the folded inner surfaces of the adjacent thin paper, that is, they are inserted alternately. It is laminated in a rolled state. Then, when one or a plurality of stacked thin paper sheets are taken out, the subsequent thin paper sheets are partially ejected to the outside. The tissue paper may be folded in three or four as long as it can be pulled out in a pop-up manner.

The tissue paper to be accommodated may be sanitary tissue paper such as tissue paper, toilet paper, kitchen paper, paper hand towel, paper cloth, and wiper. The basis weight of the thin paper with one ply is preferably 10 to 25 g / m ² , and the thickness of the thin paper with two plies is preferably 130 to 250 μm. The basis weight is based on the basis weight measuring method of JIS P 8124 (1998).

The dimensions of the thin leaf paper laminate 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) orthogonal to the length direction of the outlet when viewed from above. The height can be about 80 to 150 mm and the height (z direction) can be about 30 to 100 mm. Such a laminate of tissue paper can be produced, for example, by a rotary type or a multi-stand type interfolder.

As shown in FIG. 1, the housing 1 has a dehiscence line 20 on the upper surface 10. As shown in FIGS. 1 and 2, the dehiscence line 20 includes a linear center line 21 and end lines 22 and 22 formed at both ends of the center line 21, and includes the center line 21 and each end. It is formed in connection with the portions 22 and 22. The center line 21 extends in the x direction in FIG. 1 and is located at the center of the housing 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 form, the both end lines 22 and 22 have a line-symmetrical shape, but the both end lines 22 and 22 are not line-symmetrical and may have different shapes and sizes.

The x direction in the figure corresponds to the width direction of the thin paper laminated body housed in the housing body 1. The x direction is orthogonal to the drawing direction when the thin paper is pulled out from the laminated paper of the thin paper, and corresponds to the extending direction of the end portion of the thin paper that is pinched when the thin paper is pulled out. Further, the y direction corresponds to the depth direction of the laminated body of tissue paper housed in the container 1. Further, in this embodiment, the direction perpendicular to the xy plane is the z direction. The z direction corresponds to the height direction of the laminated thin paper. In the illustrated housing 1, a laminated body whose length in the width direction is longer than the length in the depth direction is housed.

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

The dehiscence line 20 shown in FIGS. 1 and 2 is a line capable of forming an outlet by dehiscence by the user at the start of use. In the illustrated form, the dehiscence line 20 is formed by perforations, but may be other linear fragile portions or markers as long as the user can dehiscence at the start of use. Further, in the illustrated form, the center line 21 is a single line, but the center line 21 may be two lines extending substantially in parallel at predetermined intervals, and in that case, the two lines. Can be dehiscenced to remove the part between the dehiscence lines.

Instead of the dehiscence line 20, a cut line may be formed on the upper surface 10. That is, an outlet may be formed in advance on the upper surface 10 by a cut. In that case, in order to prevent dust and the like from entering the inside of the housing and contaminating the thin paper before the start of use, the entire thin paper product 100 including the laminated thin paper and the housing 1 containing the laminated paper is used. , 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 quadrangle, specifically a part of a rectangle in a top view, but is not limited to this shape. For example, it may be a part of a quadrangle 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 a state after the dehiscence line 20 shown in FIG. 2 is dehiscenced. As shown in FIG. 3, a slit-shaped outlet 25 is formed by dehiscence of the dehiscence line 20. By dehiscence of the end line 22 of the dehiscence line 20, an end slit 22A is formed, whereby a flap (end flap) 32 can be formed at at least one end of the outlet 25. can. The flap is a planar member having a predetermined area, which is partially integrated with the upper surface 10 and can move so that the portion separated from the upper surface 10 can be opened and closed. The flap is sometimes called a hinge.

The flap 32 has a maximum length L _fx in the length direction (x direction) of the outlet 25, and has a maximum length L _fy in the direction orthogonal to the x direction (y direction). Further, in the illustrated embodiment, the central flaps 31 and 31 can be formed also in the center of the outlet 25 by dehiscence of the center line 21 and the end lines 22 and 22 formed at both ends thereof. Since the central flap 31 can be flexibly curved and lifted like the flap 32, it can support the pop-up tissue paper, prevent the tissue paper from falling, and hold the tissue paper vertically (sheet holding). Contributes to improving performance). Let L _c be the length of the central slit 21A formed by the dehiscence of the central line 21. In the present specification, the slit includes a slit having a predetermined width, and also includes a linear one having a width of 0 mm and the edges of the slits contacting each other.

As described above, when the cut line is formed instead of the dehiscence line 20, the flap 32 is already formed by the cut line before the start of use. In that case, the center line 21 may remain a dehiscence line such as a perforation, and at least one of the end lines 22 may be a notch line instead of a dehiscence line. When the end line 22 is a dehiscence line, a force is applied to the end when the dehiscence line of the center line 21 is dehiscenced, and the dehiscence cannot be performed along the end line 22, so that the flap is appropriate. However, if the end line 22 is configured as a cut line and the flap is formed in advance, the flap can be reliably secured.

FIG. 4 shows a part of the cross-sectional view taken along the line II of FIG. 3 in a state where the flap 32 is lifted upward. As described above, the housing 1 is made of a flexible film, and the flap 32 is also made of a flexible film. Therefore, when the flap 32 receives a force from the thin paper when pulling out the thin paper, the flap 32 can be deformed while flexibly bending. As shown by an arrow U in FIG. 4, the flap 32 is configured to open outward in the length direction (x direction in the figure) of the elongated outlet 25.

Further, the flap 32 is opened so that the length of the outlet 25 is extended. The length L _t of the outlet 25 extended by opening the flap 32 can be the sum of the length L _c of the central slit 21A and the maximum length L _fx in the x direction of the flap 32 at the maximum. In the illustrated embodiment, flaps 32 having the same size and shape are 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 a maximum length L _fx , the length L _t of the outlet 25 extended by opening the flap 32 is specifically the length L _c of the central slit 21A and the x of both flaps 32, 32. It is the sum of the maximum length L _fx in the direction (L _fx + Lc + L _fx ). When one of the flaps 32 in the illustrated form is absent (one flap 32 is provided at one end of the outlet 25), the length _Lt of the outlet 25 extended by opening the flap 32. Is the sum of the length L _c of the central slit 21A and the maximum length L _fx of the flap 32 in the x direction (L _c + L _fx ).

Further, after the dehiscence of the dehiscence line, the central flaps 31 and 31 are also formed in the center of the outlet 25 as described above. Therefore, the range of the outlet 25 formed by dehiscence of the dehiscence line 20 can be, for example, the region shown 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 in the center of the upper surface. Further, FIG. 8A shows an accommodating body 1'' in which short perforations are formed at both ends of a linear perforation in the center of the upper surface in a direction orthogonal to the central perforation. In these enclosures, the tissue paper is pulled out in contact with the edge of the outlet, so it is easy to get caught in the edge of the outlet, especially at the end of the outlet, and movement is restricted. Therefore, the container tends to float together with the tissue paper, especially when the amount of tissue paper contained in the container is reduced. When the container is lifted, it is necessary to hold the container with the hand opposite to the hand for pulling out the tissue paper, which is inconvenient.

On the other hand, by forming a flap 32 that opens outward in the length direction of the outlet 25 at at least one end of the outlet 25, it is possible to prevent such floating of the housing. FIG. 5 shows a state in which the housing 1 (thin paper product 100) according to this embodiment is used. FIG. 5 shows a state in which the thin paper P is pulled out upward. As shown in FIG. 5, when the thin paper P is pulled out, the flap 32 receives a force from the thin paper 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 P. Then, when the thin paper P is continuously pulled out, the flap 32 flexibly moves according to the movement of the thin paper P and does not hinder the movement of the thin paper P.

Further, FIG. 5 shows a state in which the first tissue paper is pulled out and the next tissue paper P'pops up. At this time, at least a part of the inner surface of the flap 32 is in contact with the thin paper P', and a frictional force is generated at the portion in contact with the thin paper P'. The thin paper P is pulled downward by gravity, but the flap 32 acts on the end face and contact surface of the flap 32 in contact with the thin paper P'because a compressive force (a force that pulls it downward (arrow D)) acts on the flap 32. It will have the function of a kind of stick, and the flap 32 can support the tissue paper P'. Therefore, the thin paper P'is less likely to fall inside the container. Further, since the flap 32 can support the thin paper P'at least a part of its inner surface, it can also contribute to maintaining the state in which the thin paper P'is vertically pulled out.

As described above, by being provided on the flap 32, the container is prevented from rising when the thin paper is pulled out, and the thin paper that is popped up after the thin paper is pulled out is prevented from falling. be able to. Further, it is possible to hold the thin paper P in a vertically pulled out state.

Further, in the conventional flexible film accommodating body 1'(FIG. 7) or the like, the outlet 25 is linear, and when the thin paper is pulled out, the thin paper is often folded and pinched at the end. .. Therefore, the container tends to rise as the thin paper is pulled out.

On the other hand, in the present embodiment, the outlet 25 is widened in the x-direction and the y-direction by opening the flap 32 (FIG. 3). As a result, the thin paper is less likely to be pinched at the edges and is pulled out smoothly, so that the floating of the container can be further reduced.

Further, since the width of the end portion of the outlet 25 is widened by the flap 32, the subsequent thin paper can easily follow the drawn thin paper, so that the subsequent thin paper does not come off at the end of the outlet. You can definitely pop up tissue paper. This also enhances the effect of reducing the drop of tissue paper into the containment body.

Further, in the conventional housing 1'(FIG. 7) in which the flap is not formed, stress is likely to be applied to the end of the outlet. Therefore, when the thin paper is pulled out one after another at the end of the outlet, the film is released. It is easily stretched and deformed. Therefore, the next drop of tissue paper tends to be more likely to occur. On the other hand, according to the present embodiment having the outlet 25 provided with the flap 32 at the end, the deformation of the end of the outlet is small. This can also contribute to the reduction of the next drop of tissue paper.

The maximum length _Lfx of the flap 32 in the length direction (x direction) of the outlet 25 (FIG. 3, the length in the x direction of the shape formed by the end slit 22A) is preferably 1 to 15 mm. It is more preferably 2 to 10 mm. Within the above range, the flap 32 can have appropriate flexibility and appropriate rigidity that can reduce both the lifting of the housing and the dropping of the tissue paper. For example, by setting the maximum value of the length _Lfx in the x direction to 1 mm or more, it is possible to reliably lift the flap upward when pulling out the thin paper, and by setting it to 15 mm or less, the pop-up thin paper is supported. It is possible to improve the effect of

The maximum length _Lfy of the flap 32 in the direction (y direction) orthogonal to the length direction (x direction) of the outlet 25 (FIG. 3, the length in the y direction of the shape formed by the end slit 22A) is It is preferably 1 to 20 mm, more preferably 2 to 15 mm. Within the above range, the flap 32 can have appropriate flexibility and appropriate rigidity that can reduce both the lifting of the housing and the dropping of the tissue paper. Further, by setting the maximum value of the length _Lfy 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 pop-up thin paper can be improved. Further, when the thickness is 20 mm or less, it is possible to prevent the contact area with the thin paper from becoming excessively large and hinder the drawing of the thin paper. In addition, it is possible to prevent the width of the outlet 25 from becoming excessively large and the thin paper from being easily dropped.

The ratio value (L _fx / L _fy ) 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, preferably 0.7 to 3. It is more preferably 1.5. Within the above range, the flap 32 can have appropriate flexibility and appropriate rigidity that can reduce both the lifting of the housing and the dropping of the tissue paper.

Further, the total length L _t of the outlet 25 when the flap 32 is opened, that is, 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 of the thin paper laminate in the x direction.

In the illustrated form, the shape of the flap 32 is a quadrangle, specifically a rectangle when viewed from above, but the shape of the flap 32 is appropriately selected according to the material of the film used and the type of tissue paper. .. As shown in FIG. 3, the shape of the flap 32 is preferably a shape in which the flap 32 has a maximum length _Lfx in the x direction at a position where the slit 21A is connected to the end slit 22A.

FIG. 6 specifically shows a modified example of the shape of the flap 32. As shown in FIGS. 6A to 6E, the flap 32 can be a semicircle, a triangle, a partial ellipse, a trapezoid, or an inverted trapezoid. As shown in FIGS. 6A to 6E, each flap 32 has a maximum length _Lfx in the length direction (x direction) of the outlet 25, and has a direction (y direction) orthogonal to the x direction. Has a maximum length L _fy of. As described above, the flap 32 can be a quadrangle 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 semicircle), and the like. With the above shape, the flap 32 can have a predetermined spread, so that the above-mentioned function as a flap can be satisfactorily exhibited. Of the above shapes, it is preferable that the flap 32 is a semicircle, a triangle, or a quadrangle.

The dehiscence line of the accommodating body 1 can be a perforation formed by, for example, a perforation blade on the film portion to be the upper surface 10. Further, it is also possible to use a blade having a straight blade at the portion corresponding to the end portion so that the cut line is formed at the end portion. As described above, the housing 1 according to the present embodiment can be manufactured only by changing the shape and dimensions of the conventionally used blades.

Hereinafter, embodiments of the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples.

In this example, an accommodating body accommodating a laminated body of thin paper was prepared and evaluated. The evaluation items and the evaluation method of each evaluation item are as follows.

[Sheet drop]
Tissue paper was used as the thin paper product (the thin paper products of Examples 1 to 4 and Comparative Examples 1 to 3 were prepared using "Hello Soft Pack Tish" of Universal Paper Co., Ltd., and Examples 5 to 6 and Comparative Examples were used. 4 to 6 tissue paper products were prepared using "Tissue Paper without outer box" by Aeon Co., Ltd.). Further, the tissue paper is 150 sets (300 sheets) consisting of one set of two sheets, and each set is folded in two and folded into a laminated body that is taken out in a pop-up manner. The tissue paper product containing the tissue paper laminate contained in the containment body was placed on a flat mounting surface. About half of the first set of tissue paper was pulled out from the outlet, and the central part of the tip in the x direction was sandwiched between eyeball clips ("Kuri-17" manufactured by KOKUYO Co., Ltd.). Pass the hook of the push-pull gauge (manufactured by Imada Co., Ltd., model number: Z2-20) through one hole of the handle of the eyeball clip, and take 0.4 to 0.6 seconds at a constant speed to accommodate the container. The tissue paper was pulled out perpendicular to the top surface of the paper. This operation was performed on all the contained tissue paper sets. At that time, the number of sets in which the pop-up did not continue and the subsequent tissue paper did not come out from the take-out port and fell into the inside of the container was recorded as the number of sets dropped in the sheet. The smaller the number of seat drop sets, the better the container is, the less likely it is to drop.

[Inclusion float]
Each time the above-mentioned tissue paper was pulled out, it was confirmed whether or not the container was pulled by the tissue paper and the container was lifted from the mounting surface. The number of sets of tissue paper remaining in the containment body when the containment float occurred was recorded as the number of remaining sets when the containment float occurred. The smaller the number of remaining sets, the less likely it is that the container will float.

[Sheet holding performance]
When the above-mentioned tissue paper was pulled out, when one set of tissue paper was taken out, it was observed whether the next set of tissue paper was held in the direction perpendicular to the upper surface of the container. The 11th to 20th sets of tissue paper were observed and recorded. The sheet holding performance was evaluated as follows.
⊚: The number of vertically held sets is 8 or more 〇: The number of vertically held sets is 5 to 7 sets Δ: The number of vertically held sets is 3 to 4 sets ×: The number of vertically held sets Is 2 pairs or less

(Example 1)
As shown in FIGS. 1 and 2, a tissue paper product including a container having a dehiscence line on the upper surface including a center line and end lines at both ends thereof and a laminated body of tissue paper housed in the container was prepared. .. As shown in FIG. 1, the center line of the dehiscence line extends in the x direction at the center of the upper surface of the container in the y direction. The container was made of polypropylene (PP) film (film thickness: 40 μm), and the laminate was packaged in a caramel packaging format. The depth (length in the y direction) of the container was about 205 mm, the width (length in the x direction) was about 100 mm, and the height (length in the z direction) was about 50 mm. The laminated tissue paper contained is a pop-up stack of 150 sets (300 sheets) of double-layered tissue paper, with a width (x-direction length) of 205 mm and a depth (depth) (as a whole). The length in the y direction was 100 mm, and the height (length in the z direction) was 50 mm.

The dehiscence line on the upper surface was dehiscenced to form an outlet as shown in FIG.
