Disposable diaper

The invention relates to a disposable diaper for babies and toddlers and people with incontinence, with which they can be kept clean and dry, avoiding extensive contamination and irritation of the skin and cleaning operations on the child and diaper pants are no longer necessary.

The disposable diaper according to the invention is characterized by a reinforcement or support equipment, a first tight layer with two central openings or recesses arranged one behind the other accordingly adjacent to the primary urine and stool delivery sites an absorbent layer and a second impermeable layer which together with the first form the absorbent Layer includes.

The support equipment or reinforcement has ins-56- (Doss. 4U5) -NöE. (7)

special on both rare recesses that have a tight Allow the diaper to rest on the thighs.

Other features and advantages of the invention will appear from the following description, which proceeds refers to the attached drawings; show it:

1 shows an applied diaper according to the invention;

Pig. 2 a longitudinal section through the V / indel transversely to Layer arrangement;

Pig. 3 is a plan view of a second embodiment

the v / indel, from which parts have broken out to make individual layers visible and

Pig »4 a plan view of the mounting equipment of the diaper according to Fig« 3 ·

The diaper shown in Figures 1 and 2 has a generally planar, elongated rectangular shape and is through a reinforcement or support equipment or "mask" 1 is formed, the ends 2 and 3 of which over the layer package of the V / indel protrude, but the width of which is less than that of the other layers. This maintenance equipment 1 is provided with at least one hole or an opening (4, 4a in the example shown, of aenen in particular the hole 4 should be present in all upper layers of the diaper).

This holding equipment is made on the one hand by a first layer 5 of soft-to-the-touch, permeable Material like paper tissue and covered on the other side by a first impermeable layer 6, which

109834/0249

for example made of plastic or cellulose (or cellulose derivatives) consists. The two layers 5 and 6 also have openings which correspond to the openings 4 and 4a of the "mask" 1 correspond.

Further has the diaper between the first impermeable layer 6 and a second impermeable layer 7, a second absorbent layer comprising a sub-layer 9 is formed of wadding of cellulose or absorbent cotton in the embodiment shown by a layer of paper web 8 and '%. This second absorbent or absorbent layer also has openings which correspond to the openings 4 and 4a of the "mask" 1.

The cohesion of these layers can be achieved by lightly gluing the layers on top of one another or simply by pressing them together can be achieved. However, the second impermeable layer is longitudinal with the first impermeable layer 6 of the outer circumference welded or glued in such a way that under the layer 6 a relatively tight pocket arises. . J

It should be noted here in particular that the outer layer 7, when the diaper is put on, is wider or larger Can be expanded, as the layer 6, in such a way that a kind of pocket is formed and the absorbent layer 8, 9 is not compressed when putting on the diaper and despite the diaper being securely attached, there is enough space for Excrement is created.

In the embodiment shown, the second impermeable protrudes Layer 7 beyond the rest of the diaper and

10983A / 0249

has self-adhesive flaps or tabs 10, which according to Place the diaper around the child's thighs and stomach, overlapping each other, so that the diaper can be attached in the manner of a pair of pants.

Ends 2 and J5 of the "mask" are at the one shown Embodiment assembled with a carrier 11, which goes over the shoulders and neck of the child and serves to to hold the diaper in place. For this purpose the ends 2 and 3 can be provided with means for hooking or adjusting which allow a good adjustment of the diaper.

The diaper is put on in such a way that the urine escaping from the child is absorbed through the opening 4a to the second Layer 8, 9 arrives, in an area where it has a considerable thickness of absorbent Has material 9, while the child's stool through the opening 4, which is in particular always to be provided, into a The area of the absorbent layer 8, 9 reaches where the second impermeable layer 7 forms a kind of pocket or receptacle is formed.

In this way, the child's urine and stool are stored in the second absorbent layer 8,9 captured and collected, which is arranged between the two dense layers 6 and 7, which is an effective Offers protection for the child from getting considerably wet and dirty.

In the second embodiment shown in Figures 2 and 4, the diaper is similar to that already described, i.

109834/0249

it has a first dense or impermeable layer 6 and a second impermeable layer 7, the latter forming a pocket and made of, for example, plastic consists. The impermeable layers β and 7 are welded or welded to one another along their circumference. connected to form a cover for the holding equipment 1 and the second absorbent layer, the latter here by a single layer 12 of cellulose or wad of cellulose or hydrophilic cotton or the like, approximately ( constant thickness is formed. The first absorbent layer 5 is on top of the first impermeable layer 6 arranged outside the shell formed by the layers 6 and 7.

In this embodiment ends 2 and 3 are the Retaining equipment 1 arranged within the envelope formed by the impermeable layers 6 and 7, but the entire stack forming the diaper is provided with holes 13 which allow hooking of a carrier 14 for fastening the diaper.

there are openings or holes 4, 4a (except in the layer 6) in the absorbent top layer 5 * in the support equipment 1 and provided in the second absorbent layer 12.

Finally, the support equipment 1 has arcuate cutouts 15 which allow the diaper to fit snugly against the Allow thighs, so that it is avoided that urine or stool can escape between the skin and the diaper.

10983A / 02A9

The mounting equipment 1 also has an opening 16 and slots IJ, which allow the reinforcement or mounting equipment and thus the diaper to be adapted in shape so that the latter follows the shape of the child as closely as possible and, in particular, rests well on the buttocks.

Numerous modifications of the diaper according to the invention are possible without thereby departing from the scope of the invention is left. In particular, the “mask” 1 and the layers 5 * 6, 8 and 9 can have a different number have openings 4. The thick absorbent layer 9 can extend over the entire length of the diaper and the shift can be 1, 2 or none at all (un, deux ou point) have openings.

The impermeable layer 7 can have the same dimensions as the other layers, in which case the diaper is held in place only by the ends 2 and J5 of the "mask" 1 attached to the wearer. In in this case, and if the two impermeable layers 6 and 7 are made of plastic, it is possible to use them to be welded along its entire circumference, with the complete inclusion of the second absorbent layer 8 and 9 in a (apart from the openings 4, 4a) airtight casing.

The layer 6 can be wider than the rest and serve to fasten the diaper to the wearer.

109834 / 02A9

Finally, the "mask" 1 can in certain cases be replaced by or with the first dense layer be united. So you can provide a dense film using plastics ^ which the impermeable ge layer 6 forms, the central part of which is reinforced and extended in the direction of the longitudinal axis of the diaper, under Formation of the reinforcement or the support equipment I.

An important peculiarity of the diaper is that it fits easily against the body and its Shapes closely follows and that the diaper closes tightly.

According to a variant, the diaper can be treated beforehand with talc, i.e. the free surface the first absorbent layer 5 with a thin Layer of talc can be covered.

The opening made in the support equipment 4a can be larger than the corresponding openings of the first dense layer and first absorbent layer, so that the edges of this opening 4a, which could possibly lead to injuries, are protected by soft layers are.
