Problems solved by technology

[0004] However, in the case of the absorbent pad described in the above-mentioned Patent Document 1, it is formed by affixing a separate non-woven fabric (hydrophobic or water-repellent treated non-woven fabric) or the like that is difficult to permeate the liquid on the upper surface of the top sheet. Three-dimensional pleats, so even if the three-dimensional pleats are in contact with the human body, it will not bring a tingling feeling of use and will not damage the feeling of use, but there is a problem that it cannot completely prevent sticking from the top sheet. Leakage or seepage of body fluids at the part of the device, giving the user a sense of insecurity, or discomfort when leaking or seeping out

[0136] Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

[0137] In this embodiment, for example, an absorbent article that can be used directly in underwear such as a sanitary napkin, or an internal absorbent that can be used as an absorbent article that is attached to a diaper or a diaper package such as a urine-absorbing pad. Absorbent pads used for sex articles are given as examples.

[0138] figure 1 It is a perspective view of the absorbent pad to which the first embodiment of the absorbent article or the inner absorbent article of the present invention is applied. figure 2 yes figure 1Sectional view of line II-II'.

[0139] Such as figure 1 , 2 As shown in , the absorbent pad 1 is composed of a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, an absorber 4, etc., and the liquid-permeable top sheet 2 is in contact with the human body. Surface configuration, the liquid-impermeable b...

[0169] Next, an absorbent pad 100 according to a second embodiment will be described with reference to FIG. 3 .

[0170] Fig. 3 is a cross-sectional view of an absorbent pad according to a second embodiment of the present invention.

[0171] The absorbent pad 100 shown in Fig. 3 is different from the absorbent pad 1 of the first embodiment in that the gathers 105 are different. Therefore, when describing the second embodiment, the same configurations as those of the above-mentioned first embodiment will be denoted by the same reference numerals and description will be omitted.

[0172] As shown in Figure 3, the gather sheet 105 that forms the three-dimensional gathers 106, 106 of the absorbent pad 100 completely covers the folded portion 32 of the back sheet 3, covers the side surface of the absorber 4, and bonds the starting point 151. It is bonded to the back sheet 3 so as to be located on the bottom surface side of the absorber 4 . That is, the inside of the width directi...

[0175] Next, use Figure 4 The absorbent pad 200 of the third embodiment will be described.

[0176] Figure 4 It is a cross-sectional view of an absorbent pad according to a third embodiment of the present invention.

[0177] Figure 4 In the absorbent pad 200 shown in , the top sheet 202 is different from the absorbent pad 1 of the first embodiment. Therefore, when describing the third embodiment, the same components as those in the above-mentioned first embodiment will be denoted by the same reference numerals and their description will be omitted.

[0178] Such as Figure 4 As shown in , the three-dimensional gathers 206, 206 of the absorbent pad 200 are made of the top sheet 202 and the back sheet 3. The back sheet 3 covers the bottom surface of the absorber 4 and covers the side surfaces of the absorber 4, and the upper longitudinal edge portions of the absorber 4 are folded back toward the top sheet 202 from the fold-back starting point 31 to form a fold-back portion...

Abstract

In an absorbent article (1) including a liquid-permeable topsheet (2) positioned at a surface that contacts with a human body; a non liquid-permeable backsheet (3) positioned at a surface opposite to the topsheet (2); and an absorbent body 4 provided between the topsheet (2) and the backsheet (3), a three-dimensional gather (6) is formed by a folding portion (32) at which the backsheet (3) is folded up to the topsheet (2) side along both side portions in a longitudinal direction of the absorbent body (4), and a nonwoven fabric at least partially adhered to this folding portion (32). The three-dimensional gather (6) has a free end (62) structured with the nonwoven fabric.

Description

technical field [0001] The present invention relates to an absorbent article and an inner absorbent article. Background technique [0002] It is known in the prior art that, in an absorbent pad provided as a diaper attached to a diaper or a diaper package, etc., in order to prevent leakage and seepage of body fluids absorbed by the absorbent body, a Sculpted pleats. Known as the method for forming three-dimensional pleats, for example, on the top sheet, as a pleat sheet, a non-woven fabric (hydrophobic or water-repellent treated non-woven fabric) that is difficult to permeate liquid is attached. and so on and so on (for example, refer to Patent Document 1) and the like. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-265521 [0004] However, in the case of the absorbent pad described in the above-mentioned Patent Document 1, it is formed by affixing a separate non-woven fabric (hydrophobic or water-repellent treated non-woven fabric) or the like that is dif...
