The characterizing features serve to solve this problem of the main claim. According to the invention, an elastic part is thus provided in the hip area of the diaper, as a result of which a waist seal is formed.

A preferred embodiment of the invention comprises a substantially hourglass-shaped diaper having an outer layer, an absorbent body lying on the outer layer and one covering the absorbent body Inner layer. Opposite rare plastic parts are attached to the outer layer to form crotch seals. An elastic part that forms a hip seal, is provided according to the invention and extensions of the elastic part form elastic diaper fasteners for attachment the diaper on a toddler.

The invention is explained in more detail below with reference to figures explained; show it:

FIG. 1 is a plan view of a disposable diaper according to the invention;

FIG. 2 shows a detail section in the plane of the line 2-2 of FIG. 1;

FIG. 3 shows a detailed section similar to FIG. 2 through another exemplary embodiment; and

Figure 4 is a view similar to Figure 2 of another and preferred embodiment of the invention .

In the figures, like parts are provided with the same reference numeral "A resilient and cut to form the diaper 10 has hour glass shape and forms a crotch region 12 as well as four sections of larger rer width which projections 14 and 16, etc. form. The diaper 10 includes an outer layer 22 of impermeable polyethylene or the like. An inner layer 24, preferably of non-woven polyethylene or polypropylene fibers, is attached to the outer layer 22 along the peripheral edge of the diaper 10, preferably by an adhesive which is either a hot melt adhesive or a adhesive is adhesive due to pressure. An absorbent body 26 is introduced between the inner layer 24 and the outer layer 22 and consists, for example, of rayon or the like. If necessary, wadding strips can be provided.

A pair of elastic strips is optional in the crotch area provided in a known manner and therefore not shown to form crotch seals. Form the latter however not the gist of the invention.

An elastic part 40 is attached to the outer layer by glue lines or glue dots or by other suitable devices 22 anchored. According to FIGS. 1 to 3, the elastic part 40 is attached to the outside of the outer layer 22. In another embodiment according to FIG. 4, the elastic part 40 is attached to the inside of the outer layer 22.

The elastic part 40 is stretched with the outer layer 22 State connected and thus pulls the hip area together to form a hip seal.
