Detailed description of the invention

By the way, the quality of the absorbent article contained in the package may differ between the quality of the diaper imagined from the information displayed on the package and the quality of the absorbent article actually felt when the package is opened. is there. For the absorbent article contained in the package, the impression of the absorbent article that is first touched at the time of opening is important, and when the package is opened, the package and the absorbent article are often touched at the same time. For this reason, the relative feel of the package and the absorbent article is important. The feel is influenced not only by the tactile sensation but also by the sound produced by touching the object. Further, if the sound generated when the contained absorbent article is touched is louder than the sound generated when the package is touched, the quality of the material of the absorbent article may be inferior.

INDUSTRIAL APPLICABILITY The present invention can improve the impression of the quality of the material of the absorbent article, such as the feeling of touch, by making the sound generated when the absorbent article is touched smaller than the sound generated when the package is touched. Concerning packaging and packaging of absorbent articles.

Hereinafter, the present invention will be described based on the preferred embodiment thereof.
The package 10 and the package 1 of the absorbent article according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3. Hereinafter, the packaging body of the absorbent article is also simply referred to as a packaging body. FIG. 1 is a perspective view of the package 10 and the package 1 according to the embodiment. FIG. 2 is a perspective view of a part of the package 10 and the package 1. FIG. 3 is a cross-sectional view of the front portion of the package 10 and the package 1.

The package 1 includes a package 10 and an absorbent article 100 housed in the package 10. More specifically, as shown in FIG. 1, a plurality of diapers 100 (absorbent articles) are packaged in the package 10. The absorbent article to be packaged in the package 10 is assumed to be a diaper 100, but may be another absorbent article such as a napkin.
The package 10 is a packaging material which is a flexible sheet material formed into a shape capable of accommodating the absorbent article 100 inside.
A packaging material having a preferable configuration includes a base layer 11, a coating layer 12, and a display layer 13. Hereinafter, the base layer 11, the coating layer 12, and the display layer 13 will be described.

The packaging material constituting the package 10 includes a base layer 11 made of a resin sheet. The base layer 11 is formed in a bag shape and stores a plurality of diapers 100. The base layer 11 forming the front surface 11a of the package 10 is provided with a cutting portion 11K which has relatively low rigidity and is cut and opened by the user. Here, when the user pinches and pulls the portion surrounded by the cut portion 11K with the hand 500, the cut piece 11P is formed with the cut portion 11K as a boundary.
By forming the cut piece 11P, an opening is formed in the package 10. The base layer 11 is made of, for example, a flexible and strong resin sheet. The resin sheet is made of, for example, polyolefin, polyamide, polyester, polybutylene terephthalate, polyethylene terephthalate, or the like. The resin sheet may have a single-layer structure or a multi-layer structure. Further, an aluminum vapor deposition layer that enhances light-shielding property and moisture-proof property may be provided between the layers.

The coating layer 12 is a layer provided on the outer surface side of the base layer 11 and having irregularities for scattering light by matte printing. Specifically, the coating layer 12 is composed of a resin 12 m containing a granular matting agent 12n. The resin 12m is made of, for example, an acrylic resin, an epoxy resin, a urethane resin, a polyolefin resin, a fluorine resin, a phenoxy resin, or the like. The matting agent 12n is made of, for example, silica, alumina, calcium oxide, calcium carbonate, calcium sulfate, calcium silicate, carbon black or the like.
The coating layer 12 in the package 10 and the package 1 shown in FIG. 1 is provided at a portion overlapping the cut portion 11K of the base layer 11. When the coating layer 12 is present at a portion overlapping the cutting portion 11K, it is preferable to generate a cutting piece 11P having the base layer 11 and the coating layer 12 as shown in FIG. The cut portion 12K of the coating layer 12 may be formed by breaking the coating layer when the base layer 11 is cut along the cut portion 11K, or may be formed in advance along the cut portion 11K.

The friction noise on the outer surface or inner surface of the packaging material 2 constituting the package 10 is, for example, provided as a coating layer 12 on the outer surface or inner surface of the base layer 11 by matte printing, and the matte density and the matte density in the matte printing layer. It can be adjusted by appropriately changing either or both of the number of printed lines and adjusting the density of the unevenness formed on the surface. Here, the outer surface and the outer surface are the surfaces facing the outside of the package, and the inner surface and the inner surface are the surfaces facing the inside of the package, that is, the surfaces facing the absorbent article side.
The mat density is the concentration of the matting agent 12n in the resin 12m of the mat printing layer. By increasing this concentration, the fricative noise can be increased. The number of print lines is the density at which a matte print layer is printed on the print layer. The fricative can also be increased by increasing the number of printed lines. The coating layer 12 preferably has a matte printing layer and a printing layer. The matte printing layer is a layer formed by matte printing. The printing layer is formed by applying, for example, an ink composition containing carbon black, diamine, polyol, a curing agent, an organic solvent, or the like to the surface of the base layer 11 by a gravure printing method or the like. The organic solvent consists of, for example, toluene and the like, and volatilizes after printing. The curing agent consists of, for example, isocyanate.

In order to bring the frictional noise between the packaging material and the pseudo-skin closer to the frictional noise between the diaper exterior and the pseudo-skin, the appropriate amount should be increased or decreased depending on the shape and particle size of the matting agent 12n. For example, the matting agent is preferably contained in the resin layer containing the matting agent and the resin in an amount of 1% by mass or more and 20% by mass or less based on the total mass of the matting agent and the resin. It is more preferably contained in an amount of% by mass or less.
From the same viewpoint, the particle size of the matting agent is preferably 0.1 μm or more and 50 μm or less.
