no. 2 Embodiment

[0157]

[0158] Figure 7 It is a perspective view showing the second embodiment of the pull-on diaper 1. The basic structure of the illustrated pull-on diaper 100 is the same as that of the above-mentioned pull-on diaper 1, but at the waist circumference 9 and the middle waist 7, thinner rubber threads are used as elastic members for forming gathers to form Thin mid-rise gathers 108. for Figure 7 Among the components and regions shown, the components and regions other than the center waist gather 108 are assigned the same reference numerals as those used in FIG. 1 , and their descriptions are omitted.

[0159] Specifically, the mid-waist gathers 108 are formed in the following manner: on the mid-waist 7, a plurality of elastic members (middle waist elastics) respectively extending in the circumferential direction for gather formation are provided at an average interval of less than 3 mm. part). In addition, the load for extending the entire middle waist opening 5 by 80...

no. 4 Embodiment ～ no. 6 Embodiment

[0258] According to the above-mentioned examples of the manufacturing method of the underpants-type absorbent article of the present invention, the following three kinds of underpants-type diapers are produced, which have other aspects except that the elastic properties of the waist elastic members or the elastic properties of the waist circumference are different. It has the same structure, the width of the middle waist part is 40mm, and the width of the crotch direction of the waist circumference part is 80mm.

[0259] At this time, the layer weight of the first sheet material is 20g / m 2 Spun-bonded non-woven fabrics, the second sheet material uses a layer weight of 25g / m 2 The air-permeable non-woven fabric is made of a hot-melt adhesive as the adhesive, and a silicon surfactant is used as the surfactant coated on the longer-sized elastic body that forms the waist elastic. In addition, the pitch between adjacent waist elastic members was 4 mm.

Abstract

The present invention provides a briefs-type diaper and a briefs-type absorbent article for improving over a problem of a conventional briefs-type diaper and a briefs-type absorbent article which have the same outlook and difficult in improving wearability and comfort in wearing. A plurality of waist peripheral members with a specific elasticity are disposed on the laterial side of the waist periphery at a fine clearance in order to set the elasticity of the waist peripheral part of the briefs-type diaper or the briefs-type absorbent article with a specified range, and furthermore set the rigidity of the absorbent article below a specified value according to the need, or enable the amount of coating of the adhesive on the outer layer with a specific distribution.

Description

field of invention [0001] The present invention relates to a pull-type diaper, a pull-type absorbent article used as a pull-type diaper and a pull-type sanitary product, and a manufacturing method thereof. Background technique [0002] Various pant-type diapers are marketed for older infants or adults. Since the pant-type diapers for infants are used as a type of transition from diapers to ordinary underwear, and the pant-type diapers for adults are used as a type of transition from ordinary underwear, it is preferable that these pant-type diapers can Wear it with the same feeling as normal underwear.

Similarly, for the absorbent body main body which is important in a pant-type diaper, in recent years, there has been a preference for a soft type that is close to the wearer's skin and has high durability. In addition, similarly to the appea...
