The invention is based on the object of an improved To propose diaper closure of the above type, which is easier to handle and which looks better when packaged.

To solve this problem, a diaper fastener of the type mentioned is proposed, which is characterized in that that it consists of two strips coated with adhesive on one side, of which the first strip has a first area attached to the outer skin of the diaper near the side edge and the second strip on one adjacent to the first area second region of the first strip is adhered to the adhesive layer, wherein the second strip is the adhesive layer having releasing incision and an adhesive-poorly binding outer side, and that a third area of the first Strip overlaps the outside of the second strip with an opening aligned with its incision, wherein the area of the adhesive layer released by the opening and the incision is glued to the plastic strip of the diaper is.

In a preferred embodiment, the incision of the second strip is adjacent to the third area of the first Strip arranged in its longitudinal axis.

In the following the invention is explained in more detail with reference to the figures; show it:

Figure 1 is a perspective view of the invention Diaper fastener in packaged condition;

Figure 1A is a section along the line 1A-1A of Figure 1;

FIG. 2 shows a perspective illustration of the diaper fastener according to FIG. 1 in a partially opened state; and

FIG. 3 shows a perspective illustration of the fully unfolded and ready-to-wear diaper fastener from FIG. 1,

The figures show a disposable diaper 10 with a water-impermeable one Outer skin 14 made of plastic, a water-permeable inner skin 16 and an absorbent base body in between, The outer skin 14 overlaps the side edge 18 and is attached to the inner skin 16. It forms in the edge area of the diaper a plastic strip 20 on the inside thereof.

The diaper fastener 22 according to the invention consists of a first strip 24 and a second strip 26. The first strip 24 is about three times as long as the second strip 26 and completely coated on one side with an adhesive layer 28. In the In the embodiment shown in FIG. 3, the adhesive layer 28 lies on the upper side of the first strip 24. A first region 30 of the first strip 24 is in the vicinity of the side edge 18 on the outer skin 14 of the diaper, which consists of a plastic film glued on. The first area 30 closes in the vicinity of the

509832/0334

Side edge 18, a second area 32. about this second Area 32 is the second strip 26. A third area extends from the edge of the facing away from the side edge 18 second strip 26 to the end of the first strip 24, as FIG. 3 shows.

The second strip 26 can be a paper the outside 36 of which has been treated in the manner of glue badly adheres to it. A comparison of FIGS. 2 and 3 shows that provided in the area 34 of the first strip 24 and with The opening 38 in the second strip 26 when the first strip is folded over the second strip

FIG. 2 clearly shows that when the third area 34 is folded over onto the outside 36, due to the orientation of the opening 42 and a region 40 of the adhesive layer 28 is exposed from the incision 38. The first strip 24 is now around the side edge 18 When the diaper is folded, the area 40 of the adhesive layer comes into contact with the plastic strip 20 according to FIG. 1A. the In this way, the adhesive layer exposed in the area 40 holds the diaper closure in the packaged state before it is placed on a toddler Condition on the inside of the diaper and thus gives the diaper a good appearance. They can also be used in the way arranged diaper fasteners easier to automatically pack because exposed and protruding diaper fasteners are otherwise often torn off.

If the diaper is to be put on a child, then the part of the diaper fastener lying over the inside of the diaper and folded over is the part of the diaper easily removable from the plastic strip 20 to the arrangement shown in FIG. Although the adhesive layer used enters into a very strong bond with the outer skin 14, this bond is easy to break and holds the diaper closure despite being in the position shown in FIG. 1 during diaper production and packaging. Finally, the third area 34 is the first strip 24 can be peeled off from the outside 36 of the second strip to form the arrangement shown in FIG.

In the arrangement shown in Figure 3, the adhesive layer of the third area 34 are used for fastening to another part of the diaper, while the outer surface 36 is adhesive-free Area at the junction of the back and abdomen of a well-known Provides a diaper. As a result, the adhesive layer of the diaper fastener 22 does not come into contact with the skin of the diaper, even if the diaper is poorly fitted Child in touch.
