Problems solved by technology

However, when printing a pattern by attaching ink to the outer surface of the surface-modified absorbent article, and then applying an adhesive to form an adhesive portion, if the ink adhered portion constituting the pattern is coated with If the cloth adhesive is used, since the formed adhesive part has weak adhesive force to the ink adhesion part, when the absorbent article fixed on the underwear such as shorts is peeled off through the adhesive part after use, it may cause constitutional damage. Disadvantage that the adhesive of the adhesive part remains on the underwear side
As a solution to this problem, a method of performing surface modification treatment only on the ink-adhered portion has been considered, but such partial surface modification treatment is difficult to implement on the production line, and may lead to an increase in manufacturing costs.
[0008] In addition, in order to avoid such disadvantages when forming an adhesive portion on the outer surface (non-skin-contacting surface of the back sheet) of an absorbent article printed with a pattern, if the surface of the absorbent article that is not exposed to the outside For example, as described in Patent Document 1, if a pattern is printed on the skin-contacting surface (opposite surface of the absorber) of the back sheet, when the outer surface (non-skin-contacting surface) of the absorbent article is visually observed, the pattern becomes It is not clear and may not be able to fully achieve the effect of printing patterns on absorbent articles (improvement of visual impression, etc.)

Embodiment 1

[0053] made with figure 1 and figure 2 A sanitary napkin having the same configuration as the shown sanitary napkin was used as a sample of Example 1. However, the arrangement form of the adhesive part and the pattern on the non-skin contact surface side of the sanitary napkin of Example 1 is set as Figure 5 (a) The form shown. Figure 5 The pattern arrangement form in the form shown in (a) and figure 1 The morphology shown is different. The weight per unit area is 25g / m 2 The air-through non-woven fabric is used as the front sheet 2, and the weight per unit area is 37g / m 2 The moisture-permeable sheet was used as the back sheet 3. As the absorber 4, use 50g / m 2 Super absorbent resin (SAP) with a weight per unit area of ​​160g / m 2 sheet-like absorber. The printing of the pattern is performed by a gravure printing method. In Example 1, the above-mentioned S1 / S [ratio of the total area (S1) of the adhesive portion in the underwear fixing region to the area (S) of the...

Embodiment 2

[0055] In addition to setting the arrangement form of the adhesive part and the pattern on the non-skin contact surface side of the sanitary napkin as Figure 5 Except the form shown in (b), the sanitary napkin was produced similarly to Example 1, and this was made the sample of Example 2. In Example 2, such as Figure 5 As shown in (b), in the underwear fixing region P, five rectangular main body adhesive parts 15a extending in the main body length direction X are arranged at predetermined intervals in the main body width direction Y, and in the main body width direction Y The non-adhesive-applied portion 18 is formed between the adjacent main body adhesive portions 15a, 15a. The common point of the five main body adhesive portions 15a is that they are all in the entire length of the excretory portion opposing portion A in the main body length direction X. However, the adhesive portion 15a located at the center in the main body width direction Y among the five adhesive porti...

Abstract

The invention provides an absorptive article, wherein an underwear fixing zone (P) has the smallest area among all adhesion parts (15) formed on a main absorptive body (5) and with a quadrilateral shape when overlooked, and the total area of all the adhesion parts (15) is 35-80% of the area of the underwear fixing zone (P). Moreover, in the underwear fixing zone (P), the size proportion of a pattern and the adhesion parts (15) is that: when any ink attaching part is selected from ink attaching parts (10) (patterns) covered by the adhesion parts (15) and a straight line (Q) passing through the selected ink attaching part (10) and crossing the underwear fixing zone (P) along the width direction Y of the main body is drawn, the total length of the overlapping part of the straight line (Q) and the ink attaching part (10) is less than 50% of the length of the overlapping part of the straight line (Q) and the adhesion part (15) covering the ink attaching part (10).

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins, panty liners (sanitary pads), and incontinence pads, which are fixed to underwear such as shorts and used. Background technique [0002] As an absorbent article such as a sanitary napkin, a substantially elongated absorbent article comprising a front sheet, a back sheet, and a liquid-retentive absorbent disposed between the two sheets is known. . In addition, in the absorbent article of the above-mentioned constitution, in order to fix the absorbent article to underwear such as shorts and prevent it from being displaced during use, etc., the non-skin-contacting surface (the non-skin-contacting surface of the back sheet) A technique of forming an adhesive portion by applying an adhesive to the surface is known (for example, refer to Patent Document 1). [0003] In addition, there is known a technique of providing a pattern recognizable from the outside by printing or the lik...
