Description

The present invention relates to a sheet package.

Most sanitary tissue paper such as tissue paper is housed in a carton (cardboard box). However, carton-type sanitary tissue paper has problems such as bulkiness during transportation and storage, disposal after use, environmental load, and cost. Therefore, in recent years, there has been an increasing demand for a sheet package in which a sheet such as sanitary tissue paper is housed in a flexible film packaging bag. For example, Patent Document 1 discloses a film package in which an opening (perforation) for taking out sanitary paper is formed in a flexible film packaging bag containing sanitary paper.

Japanese Unexamined Patent Publication No. 2016-188092

However, in the conventional sheet package, the outlet formed by slits such as perforations is narrow, and it is difficult to open the outlet when the thin paper (sheet) is taken out from the packaging bag. Further, the outlet formed by the slit in the film packaging bag may reduce the holding power of the sheet during use, and the sheet may fall into the packaging bag. Furthermore, since the film wrapping bag is lighter than the carton, if the remaining sheets are low during use, the film wrapping bag may be lifted up when the sheets are taken out. As described above, the conventional sheet package has a problem in the ease of taking out the sheet.

An object of the present invention is to provide a sheet package having excellent sheet take-out property.

A first aspect of the present invention is a plurality of laminated sheets, a packaging bag containing the sheets, a first slit formed on the upper surface of the packaging bag and extending in the first direction, and the upper surface.

With such a configuration, in the first aspect, the first slit is opened in the first direction and the second slit is opened in the second direction intersecting the first direction on the upper surface of the packaging bag. The first slit opened in the first direction constitutes a sheet take-out portion, and the second slit opened in the second direction constitutes a cushioning portion for the take-out portion composed of the first slit. Thereby, in the first aspect, even if stress is applied to the opened first slit (outlet) and its surroundings, the stress can be released (or dispersed) to the second slit (buffer portion).

With such a configuration, in the first aspect, the stress applied to the first slit (outlet) when the opened first slit is opened with a fingertip is released (or dispersed) to the second slit (buffer portion). Can be done. As a result, in the first aspect, the opened first slit can be easily opened with a fingertip, and the sheet can be taken out from the inside of the packaging bag (such as taking out the first sheet of the sheet contained in the packaging bag). It will be easier.

Further, in the first aspect, the presence of the second slit (buffer portion) extending in the second direction intersecting with the first direction in which the first slit extends is held in the first slit (outlet) at the time of use. The periphery of the first slit can be bent (or the first slit is deformed following the weight of the seat) with respect to the weight of the seat. Thereby, in the first aspect, the holding power of the sheet is maintained, and it is possible to prevent the sheet from falling into the packaging bag during use (hereinafter referred to as the sheet from falling).

Further, in the first aspect, the frictional force (or resistance force) applied to the first slit when the sheet is taken out (or pulled out) from the first slit (outlet) during use is released to the second slit (buffer portion). Can (or scatter). As a result, in the first aspect, even if the remaining sheet is reduced during use (that is, the weight of the sheet package is reduced), the film packaging bag is lifted up when the sheet is taken out (hereinafter, packaging). It is possible to prevent the bag from being lifted.

In addition, the first slit can be reliably bent with respect to the weight of the sheet held in the first slit during use. Further, since the second slit intersecting with the first slit is opened continuously with the first slit, the sheet in the packaging bag can be grasped by inserting the fingertip into the second slit, and the grasped sheet can be grasped. It can be taken out from the first slit (outlet).

With such a configuration, in the second aspect, the opened first slit (outlet) becomes easier to open with a fingertip, and the sheet can be taken out from the inside of the packaging bag more easily. In addition, the holding force of the sheet by the first slit (outlet) during use is further maintained, and it is possible to further prevent the sheet from falling during use. Further, even if the remaining sheets are reduced during use, it is possible to further prevent the packaging bag from being lifted when the sheets are taken out.

With such a configuration, in the fifth aspect, the first slit is opened in the first direction on the upper surface of the packaging bag, and the second slit and the third slit arranged in the first direction intersect the first direction. It is opened in each direction. As a result, the stress applied to the opened first slit (outlet) and its surroundings can be released (or dispersed) to the second slit and the third slit (two cushioning portions), respectively. In addition, the first slit (outlet) can be reliably bent with respect to the weight of the sheet held in the first slit (outlet) during use.

Thereby, in the fifth aspect, the opened first slit (outlet) becomes easier to open with a fingertip, and the sheet can be taken out from the inside of the packaging bag more easily. Further, in the fifth aspect, the holding force of the sheet by the first slit (outlet) at the time of use is further maintained, and the sheet can be further prevented from falling during use. Further, in the fifth aspect, even if the remaining sheets are reduced during use, it is possible to further prevent the packaging bag from being lifted when the sheets are taken out.

In the sheet laminated body SL, the sheets ST can be pulled out one by one through the first slit 20 (outlet OP) formed in the packaging bag 10.

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

Further, the dimensions of the laminated body SL of the sheet ST are such that the length of the sheet package 100 in the longitudinal direction (X direction) is about 80 to 250 mm, and the depth is orthogonal to the longitudinal direction (X direction) of the sheet package 100 when viewed from above.

For example, the blending ratio of the pulp can be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

The pulp composition in the sheet ST (paper sheet) includes, for example, softwood pulp such as NBKP (conifer kraft pulp) and NUKP (conifer unbleached pulp), and LBKP (softwood kraft pulp) and LUKP (hardwood unbleached pulp). Can be used in any ratio with the hardwood pulp. In particular, it is preferable that the pulp composition has a larger ratio of softwood pulp to hardwood pulp. The ratio of softwood pulp to hardwood pulp is preferably 50:50 to 80:20. Recycled 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 non-woven fabric, depending on the number of plies. The basis weight is measured in accordance with the provisions of JIS P 8124.

The thickness of the sheet ST (paper sheet) is not particularly limited, but for example, a paper thickness measured under the environment of JIS P 8111 (1998) can be adopted. For example, the paper thickness of the paper sheet constituting the sheet ST is preferably 50 to 500 μm, and more preferably 60 to 330 μm per ply.

The paper thickness is measured by sufficiently adjusting the humidity of the test piece under the conditions of JIS P 8111 (1998), and then dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) under the same conditions. ) Is used to measure in a 1-ply state. Specifically, after confirming that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table and move the memory of the dial thickness gauge to set the zero point. Then, raise the plunger, place the sample on the test table, and read the gauge when the plunger is slowly lowered. At this time, the plunger is only placed. The terminal of the plunger is made of metal so that a circular plane having a diameter of 10 mm hits the paper plane perpendicularly, and the load at the time of measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing the measurement 10 times.

Further, the paper sheet constituting the sheet ST may be embossed. Such embossing is not shown by a known contact embossing method, an edge embossing method, or the like, in which embossing (not shown) is pressed against both ends of a paper sheet and a plurality of paper sheets are laminated, or by a known pin embossing method. A paper sheet in which a pin is pierced into a paper sheet to form pin embossing on one surface of the paper sheet, and a water-soluble adhesive (such as starch) is heated and melted by a known embossing method to form a laminated paper sheet. There are some that form embossing by adhering (not shown).

The packaging bag 10 constituting the sheet packaging body 100 is made of a flexible film. Further, the packaging bag 10 is manufactured by caramel packaging. Specifically, both ends of the tubular flexible film are formed by folded and bonded (sealed) sealing portions 30 and 40.
