Embodiment Construction

[0030] The pantiliner 1 will be described as an example of the body fluid treatment article of the present invention. figure 1 is a top view of the sanitary pad 1; figure 2 (a) is to figure 1 The area shown in II is enlarged to show the figure of its outline; figure 2 (b) is figure 2 The II B-II B line section of (a) is a diagram showing its outline; figure 2 (c) is to figure 2 The outline of the area shown in II C in (b) is enlarged and shown. The sanitary pad 1 has a vertical Y and a horizontal X, a virtual longitudinal centerline P-P that bisects the length dimension of the horizontal X, and a virtual transverse centerline Q-Q that bisects the length dimension of the longitudinal Y. The sanitary pad 1 is relatively The imaginary longitudinal centerline P-P and the imaginary transverse centerline Q-Q are formed approximately symmetrically.

[0031] The sanitary pad 1 comprises: an inner face sheet 2 positioned at the wearer's body side; an outer face sheet 3 posit...

Abstract

The present invention provides a body fluid treatment article wherein twisting while being worn can be inhibited, and a method for manufacturing the same. A panty liner (1) comprises: inner and outer surface sheets (2, 3); a fluid-absorption interlining (4) located between the inner and outer surface sheets (2, 3); and a leakproof sheet (5) with which the outer surface sheet (3) is covered. A fiber nonwoven fabric containing thermoplastic synthetic resin is used as the inner and outer surface sheets (2, 3), and fluff pulp is used as the interlining (4). On the inner surface sheet (2) are formed a plurality of compressed grooves (7) toward the outer surface sheet (3) in a manner that the compressed grooves (7) form a grid pattern by extending so as to cross one another respectively in the lengthwise direction (Y) and the crosswise direction (X). The compressed grooves (7) comprise a first portion formed from the inner surface sheet (2) toward the interlining (4) and second portions each provided with a bottom and formed from the lower part of the first portion toward the outer surface sheet (3) in such a manner that the interval between both of the lateral sides is reduced gradually. At the bottoms of the second portions, at least parts of the fibers forming the inner surface sheet (2) and the fibers forming the outer surface sheet (3) are in contact with each other and welded.

Description

technical field [0001] The present invention relates to body fluid treatment products such as sanitary napkins, urine-absorbing pads, and panty liners, and more particularly to a body fluid treatment product having a plurality of grooves formed on its surface along the thickness direction and a manufacturing method thereof. Background technique [0002] Conventionally, the technique of forming a plurality of grooves in body fluid treatment products such as sanitary napkins is known. For example, according to Patent Document 1, the body fluid treatment article has a top sheet, a back sheet, an absorber sandwiched between these top sheet and back sheets, and a plurality of grooves formed by compressing the top sheet toward the absorber. A hot-melt adhesive is applied between the surface sheet and the absorber. [0003] In the body fluid treatment article as described above, grooves are formed by embossing rolls. That is, a plurality of grooves are formed by passing the bodil...
