Abstract

A disposable diaper (10) is provided with: an absorber; a backsheet which is disposed at a non-skin contact surface side than the absorber; an exterior sheet which is disposed at a non-skin contact surface side than the backsheet; and an indicator (65) which is disposed at a skin contact surface side than the backsheet. On the exterior sheet, there are provided: a first region (R1) in which the indicator can be visually recognized from the non-skin contact surface side of the exterior sheet; and a second region (R2) which has a higher visual recognition property of the indicator than that of the first region (R1). At least a part of the first region and at least a part of the second region are disposed so as to overlap with the indicator.

Description

— \ — Disposable diaper Full Description BACKGROUND The present invention relates to a disposable diaper. (Lali) A well-known disposable dle nappy has an anterior midline region; a posterior median region; a bifurcated region between the anterior midline region and the posterior medial region; a pair of leg opening opening units formed between them; the nappy which Disposable after use having an absorbent material extending across the crotch area and extending towards the anterior midline and posterior midline regions In patent reference #3 a technique for a disposable nappy is disclosed ¢ to notify the wearer's assistant of the time to replace the nappy being discarded of it after use by providing 0 ramification area with a hydrophobic agent as a reagent; the hydrophobic agent causes an optical change if the reagent comes into contact with moisture. The diaper that is discarded after use in Patent Reference No. 1 has a translucent area of penetrability light FE 7 or greater; a reagent is provided at an organ located within the wafer of the translucent zone Patent References Yo Reference 1 Japanese Patent Application Pending No. 0 YYAAL—Y General Description of the Invention However, a nappy that is discarded after a To use as already mentioned suffers from the following problem. EAE

b As far as attention is focused on the diaper that is disposed of after use, as previously mentioned; A wafer with a translucent region is placed on the surface of the side not in contact with the skin as with the reagent. So; The reagent is clearly displayed on the outer surface of the disposable nappy and the disposable nappy is prepared so that the reagent is clearly visible. like that; The revealing substance is not found on the underwear; It is a unique formulation of a nappy that is discarded after use. The reagent is made clearly visible; Thus the presence of a disposable nappy after use is clearly aly; And the functional feature of the disposable diaper after use is confirmed. in the past few years; There was a tendency to cal when choosing a disposable dle diaper after 0 use; More users are asking for a nappy that feels as soft as underwear and has the functionality of a disposable nappy. These users tend to demand a disposable nappy that has underwear-like softness while performing the function of a disposable nappy. The reagent in a disposable nappy is too obvious; This makes VO some users feel that the function of the disposable diaper has been emphasized too much; and that there may be a case in which the overall texture of a disposable nappy is not well assessed after use. Consequently; The invention, Jad, was made in the light of the previously explained problem, and one of the objectives of the present invention is to provide a disposable diaper that is Hol to improve the feel of the diaper that is completely disposed after use while preserving the functions of the reagent. The current disclosure can be summarized in Disposable Diaper (Disposable Diaper 01) which has: front midline area; a posterior midline area; a bifurcated area between the anterior midline region and the posterior midline region; Disposable nappy has: Longitudinal direction of product going from the anterior midline area to the posterior Yo midline area; the transverse direction of the product perpendicular to the longitudinal direction of the product; The disposable nappy tATE

_ _ of it after use comprising: an absorbent material extending through the bifurcated region and extending through at least one of the anterior midline regions and the posterior midline regions; An impermeable backing sheet that sits on the non-contact side of the skin more than the absorbent material; outer sheet made of non-woven fabric; Apply on the non-contact side to the skin as with the backing foil; © A reagent applied to the skin contact side more than the backing and prepared to produce an optical change if the reagent comes into contact with moisture; (Cua) on the outer wafer; provided: a first area in which the reagent can be visually distinguished from the non-skin-contact side of the outer wafer; a second area with a higher optical recognition property of the reagent than that of the first area” and where at least part of the The first zone and at least part of the second zone 0 so that they overlap with the reagent Brief explanation of the drawings Figure 1 is an enlarged toric of a disposable diaper according to the model Figure 1 is a sectional view of the discarded diaper of it after use”; taken along line 1-1 shown in Fig. 1.
