Description

  The present invention relates to a packaging structure for absorbent articles, and more particularly to a packaging structure for absorbent articles such as sanitary napkins and urine pick-up pads that are used while attached to underwear (such as shorts).

A commonly used absorbent article such as a sanitary napkin is packed with a packaging sheet in a folded state with the back sheet facing outside, and when used, the sanitary napkin is taken out of the packaging sheet and the napkin is fixed to the shorts. To prevent misalignment during use.
For this reason, sanitary napkins generally have an adhesive layer for fixation, and packaging sheets generally have a release layer formed on the inner surface so that the sanitary napkin is not bonded to the adhesive layer when packaging with a packaging material. in use.

  As packaging materials for sanitary napkins, for example, polypropylene, polyester, polyvinyl alcohol, non-woven fabric, paper, and composite materials thereof are used. Usually, these materials are colored or patterned, and the contents are individual. It is invisible from the surface of the clothing.

  For example, the packaging material of the absorbent article described in Patent Document 1 has a coating material mainly composed of a predetermined resin on at least one surface thereof, and this coating material has a repeating pattern such as a turtle shell pattern and a lattice pattern, Characters and figures are formed.

Moreover, in the packaging structure of the absorbent article described in Patent Document 2, the absorbent article is provided with an adhesive layer, and the peeling layer provided on the packaging material is colored so as to correspond to the adhesive layer to conceal the contents. Is going.
In addition to giving design effects to products, these sanitary napkins require an appearance that is camouflaged to the extent that they are not known to be sanitary napkins before use. In this state, it has been proposed to make the absorbed menstrual blood or the like as inconspicuous as possible.

In addition, some packaging sheets are transparent or semi-transparent so that the contents can be seen from the outer surface of the individual packaging, but in this case, a sanitary napkin is given a colored pattern to inform that it is a sanitary napkin. I am trying not to.
For example, in the sanitary napkin described in Patent Document 3, in order to camouflage the menstrual blood spots absorbed by the contents and the absorber, a colored pattern is applied to the lower surface of the back sheet of the absorber, or a transparent or semi-skin A design sheet is sandwiched between the transparent back sheet and the absorbent body so that the design can be seen from the outside of the individual package through a transparent or translucent packaging sheet.

  In addition, in the sanitary napkin described in Patent Document 4, a print pattern is given to the peripheral edge of the absorbent core of the napkin and the outer wing portion to eliminate the impression that the sanitary napkin becomes inorganic, and the feeling of depression of the wearer Is trying to reduce.

By the way, there are a plurality of types of absorbent articles such as sanitary napkins packaged with packaging materials due to the difference in size due to the absorption capacity of body fluid such as menstrual blood. Conventionally, packaging materials for individual sanitary napkins, etc. There are no such descriptions, and although it is particularly possible to identify those that can be distinguished by size, for example, sanitary napkins may or may not have wings for attachment to shorts. However, even if it is attached to a packaging pack containing a plurality of individual packages, it is not given to each individual package.
Although the above-mentioned conventional sanitary napkins are also printed with a pattern, it is for camouflage purposes or for decoration purposes. It is difficult to solve this problem.

It is characterized in that it is applied at a position that is not visible from the outside of the underwear.
The invention according to claim 3 is the absorbent article packaging structure according to claim 2, wherein the joining means is an adhesive layer applied to an underwear attachment surface of the absorbent article, and the release sheet is joined to the adhesive layer. Is fixed to the packaging sheet, and character information about the absorbent article is formed on the release sheet.
According to a fourth aspect of the present invention, there is provided the absorbent article packaging structure according to the second aspect, wherein the joining means is an adhesive layer applied to an underwear attachment surface of the absorbent article, and the packaging sheet is the adhesive layer. The character sheet information is formed on the packaging sheet, and is subjected to a peeling process.
The invention of claim 5 is the absorbent article packaging structure according to claim 2, wherein the joining means is a colored adhesive applied to an underwear attachment surface of the absorbent article, and the character information is the adhesive. It is formed by.
The invention of claim 6 is the packaging structure of an absorbent article according to any one of claims 1 to 5, wherein the character information is formed on a curved surface portion that is integrally folded. It is the packaging structure of an absorbent article.

According to the present invention, when carrying an absorbent article such as a sanitary napkin, information on the contents can be acquired simply by looking at the individual packaging, so there is no possibility of mixing up the products. Also, by applying character information and design information to the absorbent article and the transparent or translucent packaging sheet, respectively, it is possible to make the difference in color tone or make the characters easier to see by adding light and shade. Can be prevented.
