Problems solved by technology
In particular, it was found that such articles generally come in one size to deal with a range of body sizes, but even within the compatible range, as the upper limit of the thigh is approached, when the wearer flexes the thigh, the upper part of the thigh The surface is also prone to close contact with the lower edge of the wing portion of the ventral portion
[0006] In the course of developing a technique for providing a wavy portion at the lower edge of the wing portion as a technique for solving such a problem, the present inventors have noticed the following problem: due to the movement of the legs, the bulge outward in the wavy portion The protruding part is folded between the front of the diaper and the skin, which not only damages the appearance, but also causes leakage and deterioration of wearing comfort.

Embodiment Construction
[0048] Figure 1 to Figure 6 An example of a belt-type disposable diaper is shown. The symbol X in the figure represents the full width of the diaper except the connecting belt, and the symbol L represents the full length of the diaper. A hot-melt adhesive used as a bonding means for bonding components on the back side. The hot melt adhesive can be applied by slit coating, continuous line or dotted line coating, spiral, Z-shape, etc. spray coating, or pattern coating (hot melt bonding by letterpress method) Coating is carried out by a known method such as transfer of agent). At the fixing portion of the elastic member, it is possible to apply a hot-melt adhesive to the outer peripheral surface of the elastic member instead of these methods or together with these methods, and to fix the elastic member to an adjacent member. As the hot-melt adhesive, there are, for example, EVA-based, adhesive rubber-based (elastic), olefin-based, and polyester-polyamide-based adhesives, which...

To prevent a projection section which expands to the outside in a wave-shaped portion from becoming folded between the surface of a diaper and the skin. A lower edge (70, 75) of a wing part (WP) has awave-shaped portion (80) having a plurality of crest sections that expand outwardly. To a portion of a side flat part (SF) more toward the center in the width direction than the wing part (WP), a side elastic member (64) and a planar gather that is contracted in the front-back direction (LD) by the side elastic member (64) are provided. The side flat part has an overlapping range (77) in which afront-back direction range where the contraction force of the side elastic member (64) acts overlaps with at least a part of a front-back direction range of the wave-shaped portion (80). The maximum extension of the planar gather is 150 to 350%, and a width direction (WD) interval of the side elastic member (64) and the wave-shaped portion (80) in the overlapping range (77) is a maximum of 15 to 50 mm and a minimum of 5 to 20 mm.
Description
technical field [0001] The present invention relates to a tape-type disposable diaper with improved fit around the legs. Background technique [0002] There are three main types of disposable diapers: belt type, shorts type, and pad type. Among them, the belt-type disposable diaper is worn by connecting the connecting parts provided on the left and right sides of the back part to the outer surface of the abdomen part after being fitted to the body in an unfolded state. [0003] A general belt-type disposable diaper has: a crotch portion including the center in the front-rear direction; an abdomen portion extending forward from the center in the front-rear direction; and a back portion extending from the center in the front-rear direction to the rear side, at least the back portion has Wing parts protruding to the left and right sides of the width direction than the crotch part, the abdominal part and the back part have an intermediate part between the left and right wing pa...
