Through the last steps in it, the folded diaper area in its the central area of the diaper is slightly bent, to hold the folded position at least until the adhesive blobs 37 form the folded structure the diaper was put on the child. After that, the 5 is maintained in this area. The diaper will Effect of use, but to maintain it attached to the child by having the Structure not essential. In carrying out the- corners of the hip part that covers the abdomen so far This function could use other means to pull the child's waist as it is possible (e.g. staples, seams, etc.), with the and the corners of the underlying part with the Blobs 37 are preferred. An adhesive that is used for io first mentioned corners in an overlapping position The purpose is suitable is to attach a polyethylene adhesive so that the diaper fits the child's hips substance with a plasticizer, as it already surrounds with soft. The overlapping corners are in train on the gluing of the pad 21 with this position by means of safety pins or Sub-layer 22 has been described. of the tape fastener 32 held. In the latter

After such folding, the edges of the diaper) The torso of the child are the different areas of this embodiment than would be possible if the diaper is to be folded flat in a straight form, the diaper being put on in a rectangular form. This tightness by the glue blobs 37 held in place is extremely important, since it is not only important. Those lying to the side of the lines 33 and 36, the appearance, but also the effectiveness of the folds, are essentially parallel and the product is favorably influenced. Although they are adjacent to the longitudinal axis of the diaper and can be inwardly curved, waterproof strips, such as.

In use, the diaper is placed on the surface on which the baby is placed and the natural movements of the child causing the folded construction of the diaper, and one end is pulled apart. The turned-up area of the diaper in the middle one of the outer areas ^ and E (which is bent at the edge part as shown in Fig. 6. In this state the diaper extends and the fasteners 32 open become the side edges the fold in the way), which come to lie under the hips, are touched slightly downwards in the folded area and bent sideways in the opposite direction, so that the corresponding side flaps are pulled outwards so that the diaper is at the edge in this In the area, assume a position in which it is pulled apart, the position thereon on the inner, rear and front cups, side flaps31, as shown in FIG attach to areas / 1 and E. In this position, the tabs are held against one another. The child will then act on the part of the win-soaking diaper or place the diaper under the hips, lowering it to a minimum and giving the absorbent the thighs. to the side in the middle and with the material inside the diaper a sufficient slight distance from the longitudinal center line in the direction of the curved end and thus the absorption capacity of the diaper. In this position, the other shows as much as possible to exploit and prevent the same-end of the diaper downwards and lies behind the early soiling of the clothing that covers the baby's legs. Then the lower end of the baby comes in contact. Since the diaper shape of the diaper is initially rectangular upward between the child's legs 65, a maximum of the dim is brought to a position in which it comes close to the sorbent area and the absorbent material in the front waist part of the child, and most economically in the if this end is turned up, it is then kept spread out in the same area, which is the case with diapers for one-time use.

As mentioned above, it is exerted by uncreped folds of the diaper and Another advantage is that the cellulose wadding layers 25 are larger in the transverse direction to the diaper length oriented so that the machine direction is the same as the lengthwise direction of the diaper. As a result of that Crepe lines running across the length of the diaper. the machine direction of the wrinkles to the largest this position runs the grooves of the crepe 30 aligns with the larger tensions, makes the larger Feim substantially parallel with the length of the diaper. the strength of the wrinkles in the machine direction plus It is a fact that moisture lost from yielding to that achieved by creping Sheet of non-creped paper is absorbed, after padding 21 more tear-resistant and therefore leads to fewer cracks Directions on the sheet with essentially. So by tearing the pad 21 at the same speed is absorbed, e.g. 35 prevented, surprisingly the tat-wetted an applied drop of water improve a neuter absorbency. The improvement essential circular area of the paper. Apparently in the degradation of the clumping Yet a drop of water lying on the surface of the cotton wool causes an effect caused by the tearing of a creped paper is applied, does not cause the crepe creases to tear or tear. As a moist area with a substantially circular 40 has already been carried out above, the agglomerates continue Form when viewed from above, but rather to an effect of the cellulose wadding's absorbency moist area, which essentially reduces the shape of the diaper and significantly reduces the has an ellipse. The main thing of the ellipse runs the surface area of the wadding, making the parallel to the grooves of the crepe or at a different speed with which further absorption takes place Words perpendicular to the machine direction of the 45 can find is substantially limited. Consequently Sheet. If the creped paper fails to one, the new diaper assembly retains its absorbency in the creped state, is determined naturally and the rate of absorption of the cellulose, that the damp area of this crepe wadding is more effective than other diaper arrangements Sheet is also substantially circular.

It follows that if any benefit is ordered from the 50).

Course of the insert with reference to the crepe lines The arrangement of the pad 21 in a way at is achieved at all, this is at most slightly less than the machine direction of the folds of the cotton ball seems to be. If all the other factors are left to run perpendicular to the length, it equates for a given cellulose wadding it is an aid to reducing fiberization Area in an absorbent diaper generally represents 55 of the folds that are associated with conventional diapers regardless of the machine direction that tend to adhere to the child's skin. A soldie Wadding stretches because the absorbency capacity of the defibrating occurs especially where the sides are remains the same. It therefore seems a controversial one of the pad 21 not pushed through underneath Question to be whether the folded area of the parts of an overhead area, as with the pre-diaper the grooves of the creping in the longitudinal or vertical described embodiment transverse direction according to the invention to the diaper according to the invention has, approximately shape, are surrounded.

It has already been said above that the bin side strips with the preferred width of approximately 2.5 cm between the padding 21 and the lower layer provide a simple protection in an economical 22 relatively resistant to shear forces against this form of leakage, (to ensure that the shear force involved does not result in separation without the convenience or appearance 5) and yet suffer easily as a result of separation. should be cash (in order to make it easier to throw away the deposit for the same reasons, ie the relatively easy). It is therefore advantageous if the under-high absorption capacity and the further saturation range of the invention resulting therefrom can be pulled off the cushion 21. If the adhesive areas 27 and 28 came outside the diaper according to the invention, a larger part of the io of the adhesive areas 23 and 24 would lie, the skin of the child with the wetted diaper areas would come into contact with the folded side edges of the blanket. From the standpoint of the absorbency layer 26, which is essentially parallel to the subsurface, while such a development will be seen to be correct layer 22, it will open outward during separation, but it is one of the causal factors in opening up, so that a transverse tearing of the bond in the If the development of bed sores in the child area 23 and 24 would result, more strength would be favorable, and for this reason it would be necessary when applying the diaper and taking into account a trouble-free separation of the diaper. Which would take place much less reliably. Who function of the porous hydrophobic cover layer 27 but the adhesive areas in the preferred is to keep the moisture quickly in the positions, then the inwardly creped cellulose wadding layers 25 to let through, 20 the side edges of the cover layer 26 in contact but the backflow of the same the darun- held with the positions of the W layers 25, so - terliegenden absorbent material to wiederste- that the pad 21 and the backsheet hen by X 22, so that in the same way, a one way valve arbei- tearing when loosening be easily separated köntet. This way the child's skin will look so neat.

Insulates moisture as much as possible from the moisture absorbed by the diaper, and is therefore less likely to cause soreness. Connection with the embodiment of FIG. 1 The cover layer 26 can consist of any material up to 6 described parts are identical, with entrial, which is not easily wetted and denotes preliminary reference numerals and not always has the porosity of a fabric, which 30 ter explained. As shown, this execution! has the deniers described above. The form in the middle part across the pad 21, a word used in the description, hydrophobically absorbent intermediate layer 38 made of creped cellulose is generally intended to refer to materials, sewing mats. The intermediate layer 38 can be placed between the ladie, if a drop of water is placed on an exposed part of the wadding 15 and hits the machine surface of the same, to allow the drop to seep away ("wet 35 direction of its creping runs across the length of the out") of the drop at least 5 Seconds needed- diaper. The purpose of the intermediate layer is to provide additional absorbent material. • The lapping corners at the child's waist are 4 ° apart if the diaper is used for a long period of time. Then the diaper is supposed to be vertically or if the child's urine output is held outside the basin of a toilet so that it is comfortably large. The solids contained in the intermediate layer 38 fall into the basin, while the additional material standing up strengthens the while the fingers of one hand grip the upper end of the diaper's absorbency, but the pad 21 surface remains and those of the other hand grip the 45 for absorbing the liquid essentially the same, upper side strip 30. Then the backsheet and the above-mentioned advantage of the elevation 22 is suddenly pulled down and away from the cushion 21 - the absorbency through the folds and side position, so that the two layers along the See and measure the fold and insert orientation of areas 23 and 24 joined by adhesive of the present invention will be peeled off from one another with the interleaving and the backsheet 50 insert 38 even more fully utilized.
22 is thrown in a trash. After the modification according to FIG. 7 to 10 looks the same, the pad 21 is dipped several times into the water that secures the sides of the inwardly folded toilet bowl until a larger part of the edges of the side flaps 31 is in one position Pre-folding the creped cellulose wadding layers over the surface of the pad 21. This becomes 25 is dissolved and floats loosely in the water. Then shown by the blobs 39 of adhesive that flush the toilet through (while holding the remaining end of the outermost areas A and E at places on the insert) until the largest part is provided, which is covered by the Tabs 31 covered the dissolved material was washed away. will. It is important that the flaps 31 in Then the remaining part for the same purpose in the turned-up area may not be fastened, so the water will be thrown. 60 that they their above-described actual The way in which the layers of the wadding layers 25 can fulfill the function. The blobs of adhesive 39 and the cover layer 26 of the pad 21 along the can be of the same type as the areas 23 and 24 for fastening the pad 21 in the longitudinal areas 27 and 28 and use the relative position on the bottom layer 22 ; it has been found, however, with reference to 65 for each of these areas 27 and 28 that an adhesive wax is completely satisfactory 23 and 24 on which the pad 21 is attached. Such a product is attached by the company lower layer 22, are indicative of Glyco Chemicals, a subsidiary of the Chardas company, easy separation of the insert from the back. les L. Huisking & Co. Inc. under the designation

Flexo wax C-Light is sold and is only heated to 43 to 49 ° C and applied. This glue solidifies and sets in about half a second if small amounts are used without pressure a bond. By attaching the tabs 31 by this method, the possibility Reduced the risk of the tabs coming off when the diaper is put on.

The method of removing the diaper of FIG. 7-10 is essentially the same as above The method described is identical, since the tabs of this embodiment are based on the one made by adhesive the points 39 attached cover layer 26 can be easily detached.

As shown in FIGS. 12 and 13, the diaper according to the invention can also be folded in other ways in order to benefit from the advantages discussed above. In the embodiment according to FIG. 12, for example, additional absorption areas F and G are formed which lie above areas A ' and E'. Such an arrangement corresponds essentially to the diapers described above with the fundamental difference that special folds are provided in the insert and an additional glue blob 37 α is applied at a point corresponding to point 37 with respect to the innermost folds, so that each of areas F and G is attached to the underlying areas A ' and E' , respectively. The flaps 31a of the waterproof lower layer 22a are folded inwardly over the areas F and G in the same way as the flaps 31 of the embodiment described above and fulfill the same function. Other structural details can be arranged approximately in the same way as explained in FIGS. For example, the absorbent pad 21 can be attached to the backsheet

ίο 22 α can be attached by means of an adhesive strip which is firmly applied in the longitudinal direction to the fold 43 on the rear side of the area A ' , while part of the same comes to lie on the other side (not shown here) of the diaper according to FIG.

This construction shows that diapers with modified

- decorative folding can be made from diapers, whose absorbent pads are wider than

the backside.

The structure of the diaper embodiment of FIG. 13 shows twice as many folds as that of FIG. 1 and 7 and results in another folding form which forms part of the present invention. In addition to the increased number of folded areas and the additional blobs of adhesive 37b which are provided when the areas F 'and G' are attached to the areas A " and E" , the structure of this embodiment can also essentially be that of FIGS . 1 and 7 correspond.

However, the reduction is not great Underlayer and from one arranged on top of it large, since the waterproof layer has the same Abmessaugbaren Cushion made of cellulose wadding layers, such as the cushion layer and thereby the or another absorbent material, liquid can escape at the side edges, stands, characterized in that what by the gauze envelope, which in this case the unio, made of waterproof material, even serves as a kind of liquid conductor, nor is it a top layer (22) and the pad (21) along which is strengthened. Divide the diaper into sections (A, B, C, D, E) - And finally, a diaper is known which consists of of the lines (33, 34, 35, 36) at least in the crotch - a waterproof base, an absorbent area initially from the outside towards the interior, upholstery and a liquid-permeable upper nen against each other and then from the inside to the 15 layer, the waterproof pad Outer sides are folded back, with the one protruding from the side and around the rest of the material layer terschicht (22) opposite to each other when turned over and firmly connected to the same. Side flaps (31) formed on edge strips, although the absorbent layer in this diaper has, which laterally enclosed the outer area of the uppermost part by waterproof material overlap the diaper. 20, it does not compare with any significant improvement. 2. Diaper according to claim 1, characterized in that the above-mentioned known diapers shows that the cellulose wadding layers (25), because of the poor fit in the crotch area, of the pad (21) are creped, the crepe, as already stated above, at right lines run in the longitudinal direction of the folds. angular, unfolded diapers are present, 3. Diaper according to claim 1 and 2, characterized in that these waterproof strips are not firmly attached to the legs, that the upholstery (21) on the body of the child are not in contact and thus still the on the surface and on all side edges moisture can run out on the sides. with a porous hydrophobic cover layer (26). The diaper tailored to the body shape has the is provided. Shape of an hourglass, which makes it easy to put on 4. Diaper according to claim 3, characterized thereby, and is practical to use. This form sets the draws that the cover layer (26) on the lower possibility of the legs, the diaper away from the torso side of the pad (21) is turned over. come down to a minimum. On the other hand is the manufacture of this type of diaper because of the waste ■ and others usually in the making of a 35 object with irregular lines occurring problems relatively expensive. Since furthermore The invention relates to a rectangular, in a part of the absorbent material in the training Longitudinally folded disposable diaper, which consists of a manure of the body shape adapted envelope part Waterproof thin flexible sheet of material and being cut away are both the absorptive an absorbent pad placed on top of it, as well as the absorption capacity of the diaper an absorbent material. substantially reduced. Another common disadvantage of the above a thin, flexible gauze pad as an under-described diaper consists in the fact that the layer and made of a sorptive material arranged on it tends to crumple up. (" smooth, unfolded absorbent pad made of ZeI- 45 This is undesirable for two reasons: If there are layers of loose cotton wool, the bottom layer is 1. It compares the absorbency Task to hold the cushion together and to reduce it to its initial capacity considerably envelop. For this purpose, the underlayer is wider and
