Disposable wearable article

Abstract

To reduce the difference in design appearance between a stretch region and a non-stretch region in a worn state. The problem is solved by a disposable wearable article characterized by having an elastic sheet stretch structure (20X) where a first sheet layer (20A) and a second sheet layer (20B) are bonded through bonding holes (31) extending through an elastic sheet (30) at a large number of bonding parts arranged at intervals, and in that: a first design (51) is printed on a portion in a stretch region (80) of an elastic sheet (30); a second design (52) is printed on a portion in a non-stretch region (70) of the elastic sheet (30); the first design (51) and the second design (52) look the same when the stretch region (80) and the non-stretch region (70) are stretched to an elastic limit;and the dimension of a design element of the first design (51) in the stretch direction measured when the elongation of the stretch region (80) is 130% or more is 80% or more of the dimension of the design element of the first design (51) in the stretch direction measured when the stretch region (80) is stretched to the elastic limit.

Description

technical field [0001] The present invention relates to a disposable wearing article provided with an elastic region having a design printing part. Background technique [0002] In disposable wearing articles such as disposable diapers, in order to improve the fit to the body surface, stretchability is generally imparted to appropriate parts such as the leg circumference and the waist circumference. As a method for imparting elasticity, the method of attaching a long and thin elastic member such as a rubber thread in a state of being stretched along its longitudinal direction has been widely used in the past. However, when it is desired to impart elasticity with a certain width In the case of this, a method is adopted in which the rubber threads are fixed in a state of being arranged side by side at intervals in width. In addition, as a means of further improving the fit of the surface, a method of attaching the elastic sheet in a state of being stretched in the stretchabil...

Problems solved by technology

[0007] However, when a non-stretchable region is provided in a stretchable structure including an elastic sheet, if the same printing is performed on the portion of the elastic sheet that becomes the stretchable region and the portion that becomes the non-stretchable region, there is a problem that the In the non-elastic area, the elastic sheet hardly shrinks, but in the elastic area, there is a certain degree of shrinkage. Therefore, the difference in the appearance of the design between the elastic area and the non-elastic area becomes large, especially in the two areas. Distortion on either side becomes apparent without becoming equal

However, since it is generally difficult to stably position the non-printed portion in the non-stretchable area during manufacture, it is desirable to print the same design on the elastic sheet
