Description

The present invention relates to individual packaging for absorbent articles.

Normally, absorbent products such as sanitary napkins, panty liners, and disposable diapers are individually wrapped in a packaging sheet, folded into three together with the packaging sheet, and the edges of the packaging sheets are sealed by heat sealing, etc. It is provided in individual packaging.

The packaging sheet is made of a nonwoven fabric made from polyolefin-based thermoplastic synthetic resin fibers and a release paper, which is a base material such as paper coated with a release agent, and covers the adhesive layer of the absorbent article. Often. Therefore, in recent years, when there is a need to contribute to the Sustainable Development Goals (SDGs), packaging sheets made of multiple materials are difficult to recycle and are bulky when made into multiple pieces. Since combustion energy is required to incinerate resin fibers (nonwoven fabrics), improvements have been strongly desired.

To address these problems, for example, Patent Document 1 discloses a body fluid absorbent material having a release member (packaging sheet) in which a release layer, a thermoplastic resin layer, and a nonwoven fabric layer are laminated in this order. Although this release member has the functions of a nonwoven fabric and release paper integrated, it still uses synthetic resin fibers.

By the way, when using other base materials instead of synthetic resin fibers as the material for the packaging sheet, another problem arises. For example, there is the problem of wanting to satisfy the characteristics of nonwoven fabrics made of synthetic resin fibers, such as texture, feel, and flexibility, and the problem of wanting to suppress the sound of packaging sheets peeling off each other when opening the package, while still being easy to open. However, it was extremely difficult to actually use other base materials.

As shown in FIG. 3, the packaging sheet 14 has a release layer 24 on a surface facing the adhesive layer 23 provided on the backsheet 13. By not forming a release paper on the packaging sheet 14 and providing the packaging sheet 14 with release performance, it is possible to reduce the amount of waste when individually wrapped. The release layer 24 has a function of being easily peeled off even if it comes into contact with the adhesive layer 23 provided on the backsheet 13. The shape of the release layer 24 is not particularly limited, but it is preferably the same shape as the adhesive layer 23. The peeling process for forming the release layer 24 is not particularly limited, and for example, a release agent such as a thermosetting or UV (ultraviolet) curable silicone resin, a fluorine resin, an isocyanate resin, etc. is applied to the adhesive layer 23. The peeling layer 24 can be formed by applying the peeling layer 24 to the opposing surface facing the . Moreover, the coating amount of the release agent can be similarly set appropriately.

Furthermore, it is preferable that the packaging sheet 14 is provided with a knob 22 at the end in the longitudinal direction. By providing the knob 22, the absorbent article 10 can be easily peeled off from the packaging sheet 14 when the individual package 1 is opened. The knob portions 22 may be formed at both ends of the packaging sheet 14, respectively, since the opening operation becomes easier. The shape of the knob 22 is not particularly limited, and can be appropriately set to a semicircular shape, a rectangular shape, a trapezoidal shape, or the like. The knob portion 22 can be formed by cutting the original fabric of the packaging sheet 14 into the shape of the packaging sheet 14, including the knob portion 22.

On the other hand, since the knob portion 22 is made of a paper base material separate from the packaging sheet 14, the knob portion 22 can be formed without a special cutting die. FIG. 4 is a plan view schematically showing the configuration of an individual package 1 for an absorbent article before folding according to another embodiment of the present invention. As shown in FIG. 4, the knob portion 22 is adhered to the longitudinal end portion of the packaging sheet 14. As shown in FIG. As the base material of the knob portion 22, it is preferable to use the same paper material as the packaging sheet 14 described above. In the knob part 22 of this embodiment, the proximal end side of the paper base material is adhered to the packaging sheet 14, a releasable adhesive layer (not shown) is provided on the opposite protruding part, and the distalmost part is attached to the packaging sheet 14. , is preferably non-adhesive. With this configuration, the packaging sheet 14 from which the absorbent article 10 has been taken out can be wound in the longitudinal direction X so as to wrap around the outside of the used absorbent article 10 rolled up in the longitudinal direction X. Then, the end part is fixed with the knob part 22, so that it can be disposed of without getting your hands dirty as much as possible.

(Packaging structure of individual packaging for absorbent articles)

When folding in two, the absorbent article 10 and the packaging sheet 14 are folded together along one folding line F1 extending along the width direction Y, and then the seal portions 21 are formed at both edges in the width direction Y. I can do it. In that case, it is preferable to form the seal portion 21 also at the longitudinal end of the packaging sheet 14 (the end opposite to the folding line F1). By folding the absorbent article 10 in half, the process of attaching the absorbent article 10 becomes two steps: opening the package by holding the knob 22 of the packaging sheet 14, and taking out the absorbent article 10, which reduces the time and effort required to attach the absorbent article 10. can be reduced, and the number of times the product makes noise when opening the package is minimized.

Since both edges of the individual absorbent article package 1 are closed by the seal portion 21, the absorbent article 10 can be stored hygienically. Although it can be formed by fusion by heat sealing or adhesion with an adhesive, from the viewpoint of ease of opening, it is preferable to form by adding edge embossing. Edge embossing refers to a pair of edge embossing rolls that are made up of a metal roll and a rubber roll that are narrower than the continuous sheet, to give linear edge embossing to the side edges of the packaging sheet 14 to create laminated packaging. This is a technique for integrating the sheets 14 together. Emboss patterns for edge embossing can be used as appropriate other than those shown in FIG.
