Description

The present invention relates to a sheet package.

Sanitary thin paper such as tissue paper is widely used in cartons (cardboard boxes). However, carton-type sanitary thin paper is bulky when carrying and storing, and from the viewpoint of disposal after use, environmental load, cost, etc., in recent years, sheets such as sanitary thin paper are packed in flexible film packaging bags. There is a growing demand for sheet packaging that has been processed. Some of such sheet packages have slits (perforations or the like) formed on the top surface of the film packaging bag for taking out the sanitary paper (for example, see Patent Documents 1 and 2).

However, in a sheet package having an outlet formed by a slit, it is difficult to take out the first one (or one set) of a plurality of stored sheets when taking out the sheets from the sheet package. In addition, in the outlet formed by the slit, the holding force of the sheet is lowered during use, and the sheet may drop into the packaging bag. Furthermore, since the film packaging bag is lighter than a carton, if the remaining sheets become less during use, the film packaging bag may be lifted up when the sheet is taken out, making it impossible to pull out the sheet. As described above, the conventional sheet packaging body has various problems in sheet take-out.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet package from which sheets can be easily taken out.

A first aspect of the present invention includes a packaging bag that accommodates a plurality of stacked sheets, an outlet formed in the center of the top surface of the packaging bag from which the sheets are pulled out, and a top surface of the top surface. The sheet package includes a pair of bands formed at both ends in the longitudinal direction and extending from the top surface, and an adhesive portion formed at the tip of the band.

In this specification, the central portion of the top surface of the packaging bag is a peripheral region including the approximate center (approximate center of gravity or centroid) of the top surface of the packaging bag, excluding both ends in the longitudinal direction of the top surface of the packaging bag. indicate the area. The outlet indicates the opening of the packaging bag from which the sheet is pulled out.

In this specification, a band indicates a band-shaped grip margin extending from the top surface of the packaging bag. The front end of the band refers to the end of the band on the side opposite to the end on the top surface side of the packaging bag among both longitudinal ends of the band. The sticking part indicates a part where the tip of the band can be attached to the bottom surface of the packaging bag and the tip of each band can be peeled off from the bottom surface of the packaging bag.

In the first mode, while the pair of bands are pulled from the top surface of the packaging bag along the bottom surface, the tip portions of the bands provided with the sticking portions can be attached to the bottom surface of the packaging bag. As a result, the top surface of the packaging bag bends and the opening width of the take-out port widens, so that the sheets can be taken out smoothly from the take-out port. Therefore, according to the first aspect, the first sheet (or one set) to the last sheet (or one set) are less likely to clog the outlet of the plurality of sheets contained in the packaging bag.

In addition, as described above, the top surface of the packaging bag is flexed to widen the width of the outlet opening, so that even if the number of sheets remaining during use is reduced (that is, the weight of the sheet package is reduced), Sheets are less likely to clog the outlet. Therefore, according to the first aspect, it is possible to prevent the entire packaging bag from being lifted when taking out the sheet (hereinafter referred to as lifting or lifting of the packaging bag).

Further, by attaching the tip of each band provided with the adhesive portion as described above to the bottom surface of the packaging bag, the packaging bag is crushed and the distance between the top surface and the bottom surface of the packaging bag can be shortened. As a result, the gap in the packaging bag is reduced, and the distance between the sheets accommodated in the packaging bag and the outlet can be shortened. Therefore, according to the first aspect, it is possible to prevent the sheet from falling into the packaging bag during use (hereinafter referred to as falling or sheet falling).

A second aspect of the present invention is the sheet packaging body according to claim 1, wherein the outlet is formed of a slit extending in the longitudinal direction, and the pair of bands are connected to both ends of the outlet. is. In this specification, a slit is a continuous cut, an elongated opening, or the like, and a continuous cut may be formed by breaking perforations. Also, connecting to both ends of the outlet means that each band extends from a portion of the top surface of the packaging bag adjacent to both ends of the outlet in the longitudinal direction of the top surface.

In the second aspect, since the pair of bands is arranged near the outlet, the tip of each band provided with the sticking portion as described above is attached to the bottom surface of the packaging bag, so that the outlet is secured to the outlet. The opening width of is easy to widen. As a result, in the second aspect, the sheet is less likely to clog the outlet, and lifting of the packaging bag can be further prevented.

A third aspect of the present invention is a sheet packaging body in which the slit and the pair of bands are formed by partially tearing the top surface. In this specification, the top surface is partially torn and formed means that the top surface is partially torn to form a slit, and the torn part of the top surface forms a band. In this case, the pair of bands may be configured as at least a part of the outlet that constitutes the slit.

In the third aspect, since the slit and the band are formed by tearing a part of the top surface, it is not necessary to provide the pair of bands as separate members from the packaging bag. Therefore, according to the third aspect, the sheet package can have a simple structure, and the product cost of the sheet package can be suppressed.

Further, in the third aspect, a slit is formed by tearing a portion of the top surface, and a pair of bands can be configured in which the torn portion of the top surface is connected to both ends of the outlet. This makes it possible to obtain the above-described second aspect (a configuration in which a pair of bands are connected to both ends of the outlet).

Further, in the third aspect, when a pair of bands constitutes at least part of the outlet, the pair of bands can be formed at the same time by forming a slit. Therefore, in the third aspect, the sheet package can have a simpler structure, and the product cost of the sheet package can be further reduced.

Further, in the third aspect, when the pair of bands constitutes at least part of the outlet, the portion of the outlet where the slit is formed can serve as the pair of bands as it is. Therefore, in the third aspect, it is possible to prevent generation of dust such as fragments when the slit is formed in the outlet.

A fourth aspect of the present invention is a sheet packaging body in which a part of the outlet is composed of a linear slit, and the tip portion is connected to both ends of the linear slit. In this specification, a linear slit indicates a slit linearly extending in the longitudinal direction. In addition, the fact that the tip is connected to both ends of the linear slit means that the pair of bands constitutes a part of the top surface, and the tip of each band is connected to the linear slit in a state before part of the top surface is broken. indicates that it is adjacent to both ends of the .

In the fourth aspect, after part of the top surface is torn, linear slits can be formed in the top surface of the packaging bag in addition to the slits formed in the top surface corresponding to the pair of bands. . Therefore, the outlet can be configured so that the opening width of the entire outlet is not excessively large. As a result, in the fourth aspect, it becomes difficult for dirt and dust to enter the packaging bag through the outlet during use, so that a hygienic sheet package can be obtained.

A fifth aspect of the present invention is a sheet package, wherein the band extends in a direction inclined with respect to the longitudinal direction. In this specification, the direction of inclination indicates a direction that obliquely intersects with the longitudinal direction of the top surface.

In the fifth aspect, by arranging a pair of bands extending in such an inclined direction, the longitudinal dimension of each band can be increased. As a result, the length of the band can be ensured so that the tip of the band can be attached to the bottom surface of the packaging bag.

A sixth aspect of the present invention is a sheet package, wherein the band is made of an elastic member. As used herein, a stretchable member is a member that can be stretched and contracted. In the sixth aspect, by constructing the pair of bands with such a stretchable member, each band stretches, so even if each band is short in the longitudinal direction, the tip of the band can be attached to the bottom surface of the packaging bag. can be attached.

In addition, in the sixth aspect, the longitudinal dimension of each band can be shortened as described above, so that the formation area of the outlet on the top surface can be increased. Accordingly, in the sixth aspect, the opening width of the take-out port can be increased, so that the take-out port is less likely to be clogged with sheets, and the lifting of the packaging bag can be further prevented.

Moreover, each band made up of an elastic member can be contracted while the tip of the band is attached to the bottom surface of the packaging bag. As a result, in the sixth aspect, the top surface of the packaging bag is more flexed, and the width of the opening of the take-out port is more likely to widen, so that the take-out port is less likely to be clogged with sheets. In addition, since each band shrinks as described above, the packaging bag is more likely to be crushed, and the distance between the top surface and the bottom surface of the packaging bag can be further shortened. Therefore, according to the sixth aspect, it is possible to further prevent the sheet from falling.

A seventh aspect of the present invention is a sheet package, wherein the tip portion is arcuate. In this specification, the term "arcuate" means that the tip of each band is curved in a convex shape. In the seventh aspect, by forming the tip of each band into an arc shape, it is possible to construct a band that is easy to pinch (no pain or injury when pinched). Therefore, in the seventh aspect, it becomes easy to attach the tip of the band to the bottom surface of the packaging bag.

Further, in the seventh aspect, by making the tip of the band arc-shaped as described above, a part of the top surface is broken to form a slit and a pair of bands (in the case of the third aspect) , making it easier to tear a part of the top surface, facilitating the work of forming slits and bands.

According to one aspect of the present invention, it is possible to provide a sheet package from which sheets can be easily taken out.

A sheet package 100 is an example of a sheet package according to the present invention. Moreover, the packaging bag 10, the outlet 40, the band 50, and the sticking portion 60 are examples of the packaging bag, the outlet, the band, and the sticking portion, respectively, which constitute the sheet packaging body according to the present invention.

The packaging bag 10 accommodates a plurality of sheets ST. As shown in FIG. 1, the sheet ST is accommodated in the packaging bag 10 as a laminate SL in which a plurality of sheets ST are laminated. The stack SL of the sheets ST is accommodated in the packaging bag 10 such that the stacking direction (SD direction) of the sheets ST is aligned with the height direction (Z direction). The sheet stack SL is designed so that the sheets ST can be pulled out one by one through the outlet 40 (opening OP) formed in the packaging bag 10 .

From the viewpoint of pulling out the sheets ST one by one, the stacked body SL of the sheets ST is preferably a stack of the sheets ST alternately folded (so-called pop-up type sheet stacked body SL). Further, the form of the laminated body SL of the sheets ST is not limited to one that can be pulled out in a pop-up manner, and may be one in which a plurality of sheets ST are simply laminated or one in which each sheet ST is folded and laminated.

In addition, the dimensions of the laminate SL of the sheets ST are such that the length in the longitudinal direction (X direction) of the sheet package 100 is about 80 to 250 mm, and the depth direction (Y direction) can be about 50 to 130 mm, and the height in the height direction (Z direction) can be about 10 to 90 mm. Such tissue stacks can be produced, for example, by rotary or multi-stand interfolders.

The use of the sheet ST is not particularly limited, and for example, it can be applied to sanitary thin paper such as tissue paper, toilet paper, kitchen paper, and paper towels. These sanitary thin papers also include sanitary thin papers containing moisturizing ingredients (for example, lotion tissues, etc.). In addition, the use of the sanitary thin paper constituting the sheet ST is not particularly limited, and can be applied to industrial use, household use, and portable use. Among these, household tissue paper is preferably used as the sheet in the present embodiment.

The number of plies of the sheet ST is not particularly limited, but may be one ply or more, preferably two plies (two plies stacked). Further, the shape of the sheet ST is not particularly limited, but for example, it is preferable that the sheet ST has a rectangular contour shape when the two-ply sheet is folded.

Although the material of the sheet ST is not particularly limited, for example, a sheet such as paper, nonwoven fabric or cloth can be used, preferably a paper sheet. When the sheet ST is a paper sheet, a base paper made mainly of pulp is used. The pulp composition can be a known composition for paper sheets. For example, the pulp content can be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

Moreover, the pulp composition in the sheet ST (paper sheet) is not particularly limited. For example, softwood pulp such as NBKP (softwood kraft pulp) and NUKP (softwood unbleached pulp) and hardwood pulp such as LBKP (hardwood kraft pulp) and LUKP (hardwood unbleached pulp) can be used at any ratio. can. Among these, it is preferable that the pulp composition has a higher ratio of softwood pulp to hardwood pulp. The ratio of softwood pulp to hardwood pulp is not limited, but is preferably 10:90 to 80:20. Waste paper pulp may be used as the pulp contained in the pulp composition of the sheet ST (paper sheet).

The basis weight of the sheet ST is not particularly limited, but is preferably 10 to 80 g/m ² for paper and 20 to 100 g/m ² for nonwoven fabric, depending on the number of plies. The basis weight is measured according to JIS P 8124.

Moreover, the thickness of the sheet ST (paper sheet) is not particularly limited, and a paper thickness measured under the environment of JIS P 8111 (1998) can be adopted. For example, the paper thickness of the paper sheets forming the sheet ST is preferably 50 μm or more and 500 μm or less, more preferably 60 μm or more and 330 μm or less per two plies.

In addition, the method of measuring the paper thickness is, after the test piece is sufficiently conditioned under the conditions of JIS P 8111 (1998), under the same conditions, a dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) ) to measure in a 2-ply state. Specifically, after confirming that there is no dust or dust between the plunger and the measuring table, the plunger is lowered onto the measuring table, and the memory of the dial thickness gauge is moved to adjust the zero point. The plunger is then raised to place the sample on the test bench and the gauge is read as the plunger is slowly lowered. At this time, the plunger is only put on. The terminal of the plunger is made of metal, and a circular flat surface with a diameter of 10 mm is placed perpendicularly to the plane of the paper. In addition, let paper thickness be the average value obtained by performing a measurement 10 times.

Also, the paper sheet forming the sheet ST may be embossed. Such embossing may be performed by laminating a plurality of paper sheets by pressing embossments (not shown) against both ends of a paper sheet by a known contact embossing method, edge embossing method, or the like, or by a known pin embossing method (not shown). A paper sheet in which a pin is pierced into a paper sheet to form pin embossing on one side of the paper sheet, and a paper sheet laminated by heating and melting a water-soluble adhesive (such as starch) by a known embossing method (not shown) to form an emboss.

Although the form of the packaging bag 10 is not particularly limited, it may be formed of, for example, a flexible film from the viewpoint of providing ease of taking out the sheet ST. Moreover, the packaging bag 10 is manufactured by caramel packaging.
