"Bandage for feminine hygiene or incontinence"

The invention relates to a bandage for Frauenhygier.e or Incontinence with an absorbent pad covered on a surface with an impermeable back layer.

Q) 5 sanitary napkins and templates for menstrual hygiene are described in DE-PS 19 29 267. The sanitary napkins essentially consist of an absorbent pad covered on one side with a tissue or fleece and an envelope fleece, which is otherwise coated with a laundry protection film, for example made of polyethylene. Before use, adhesive strips or adhesive surfaces covered with, for example, silicone paper can be provided on the film surface opposite the permeable nonwoven cover side.

The well-known bandages are made through the thigh pressure exerted with each movement folded in the transverse direction so that the absorbent pad surface ^ is only partially applied and menstrual fluid can run past the side. Another disadvantage conventional Tying consists in keeping one squeezed Bandage applies under tight clothing and is uncomfortable to wear.

The invention is based on the object of creating a sanitary napkin that is flexible to any body or leg movement adapts without constantly deforming or crumpling. The solution according to the invention is for the initially Said bandage characterized by integrated, the bandage shape elastically stabilizing or restoring

Air cushions and bars. The air cushions, in particular as part of a flat insert, are preferably between Absorbent pad and impermeable back layer arranged. The term "web" also includes segments and grids.

By formed by the air cushion elastic insert is inventively achieved in that the surface and, to Reset of absorbent material, in particular fluff existing s _λ de absorbent core of the napkin to each applied pressure elastically and discharge elastically restored to its original shape. The bandage can therefore not crumple and ensures optimal safety, increased comfort and little application, even with tight clothing.

According to a further invention, the air cushions have predetermined breaking points acting in the manner of a pressure relief valve, so that A bursting of the air cushions is excluded even in areas with particularly high loads. Particularly beneficial In this context, it is when the originally inflated active areas of the air cushions 20 initially not inflated reserve areas border over the predetermined breaking points. This will possibly achieves that the compressed air located in particularly polluted air cushions at overpressure in an adjacent, Cross the air hose that is not yet under compressed air or that has only been subjected to low pressure can. In this way, the air cushions are prevented from bursting and parts of the is exposed to particularly high loads The bandage is automatically equipped with a restoring force adapted to the load.

The air cushions integrated into the napkin according to the invention can be selected from a multitude of non-interconnected

Here, two foils can only be used with a specially designed tool are welded together with the inclusion of air cushions. The air cushion structure can also before the material connection in one or both of the foils involved, e.g. by thermal preforming or by vacuum deformation. With this one Manufacturing process, the thickness or height of the air cushion according to the desired restoring force and / or the place of the pillow in the finished sanitary napkin, e.g. between three and five millimeters can be specified. The length and width of the individual air cushions can be the

Purpose of use varies accordingly, e.g. for Nor-Q Male pads, night pads or incontinence pads can be selected. Finally, the one containing the air cushions should be elastic insert at the front and rear longitudinal ends of the bandage have rounded shapes. It is too

favorable, the air cushion structure on the front and / or rear To make the longitudinal end of the bandage flatter than in the central area in the sense of improved wearing comfort.

The elastic according to the invention containing the air cushions Inlay can be used in parallel to the ongoing production of the

Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. It demonstrate:

a cross section through a sanitary napkin with an elastic insert containing an air cushion; a plan view of an elastic insert with a plurality of ^ οη individual air cushions; and elastic inserts, the air cushions of which are made up of a large number of air channels forming a framework exist.

The embodiment of the bandage according to the invention or The incontinence insert consists of the cross section according to FIG. 1 consisting of an absorbent pad 1 with a permeable tissue 2 and a nonwoven cover 3 located on one surface and with a protective film against the laundry 4 on the remaining outer surfaces. On the surface of the absorbent pad 1 opposite the tissue 2 there is an elastic insert 5 containing the air cushions between two foils.

Preferably, one of the two films from which the elastic insert 5 is made should also be the laundry protection film 4 form. For example, this film can be made wider on the long sides and thus also as Lateral laundry protection film serve. The laundry protection film on the side 4 is not pressurized or will not inflate.

The elastic insert 5, which is preferably made of polyethylene or polypropylene, is expediently inserted between the absorbent pad 1 and the laundry protection film 4. On the outer surface of the elastic insert 5, elastic adhesive strips 6 (or adhesive surfaces) can be used to fix the bandage

After Pig. 2, the elastic insert consists of a single one Base film 9 containing air cushion 8 and a material fit thereon, e.g. by gluing or

Welding, cover film 10 to be applied. The individual air cushions 8 according to Pig. 2 can be circular and evenly distributed on μ of the area. In particular, it is possible to manufacture the base film 9 from an endlessly manufactured film web already containing the depressions provided for the air cushion 8. In order to achieve a different elasticity of the air cushion 8 corresponding to the needs, it can be advantageous to use the individual cushions with a predetermined! To provide overpressure permeable, so acting in the manner of a pressure relief valve perforation. In general, it will be convenient in this case, only to arrange the perforation in the sense of a predetermined breaking point, that the pressure inwardly into the B _e can escape between rich non-pressurized foil parts. ()

In the pig. 3 to 5 show elastic inserts, the air cushions of which are made up of a large number of a framework Air channels 12 is composed. The main part of the air ducts 12 should preferably be contiguous Form a canal system. The shape of the air ducts is adapted to the respective needs. Along the air ducts 12 additional weld seams 13 can be provided. The welds have the function that is preferred to compress air cages or channels produced by vacuum and thermoforming. It will be in the respective Air present in the room is compressed by subsequent welding.
