Description

The invention relates to a sanitary napkin with a cover and an absorbent insert, which is made of consists of two insert parts, between which a moisture-permeable material is arranged, the Deposits are surrounded by a layer that holds them together.

According to DT-PS 11 64 020 such a structure is and trained sanitary napkin known. However, there are disadvantages with this known sanitary napkin regarding the resistance of the absorbent insert, the tightness of this absorbent insert and in particular with regard to the perfect fit to the body shape of the wearer on the freedom of movement and the resulting ailments. Furthermore, the rulership is one Such known sanitary napkins are very expensive and time-consuming despite the disadvantages to be accepted. Further there is the disadvantage of the known sanitary napkin that there is a risk of skin inflammation due to abraded particles and the sanitary napkin wrinkles on the wearer.

The present invention is based on the object to train a sanitary napkin of the type mentioned in such a way that its absorption capacity, tightness and the wearing properties in terms of fit and comfort are improved. Furthermore, the The sanitary napkin according to the invention can be constructed as simply as possible and at the same time be very absorbent.

According to the invention the object is achieved in that the cohesive layer (3) is the absorbent Deposits (1,1 ', 2) on the underside only includes at the end and that the resulting gap under the Insert (1, Γ, 2) is closed by an impermeable protective layer or layer (4), which on the one hand at the ends of the cohesive layer and, on the other hand, at the double layer below it Holding layer (5) is attached, the latter also sealing with the ends of the holding layer (3) connected is.

The surface of the intermediate layer between the insert parts of the absorbent insert consists of a hydrophilic material and contains stains made from a hydrophobic material such as paraffin.

The sanitary napkin according to the invention does not deform even if it is removed from the body fluids is saturated and its absorbent pad does not break, and the tightness of the absorbent pad is optimal peripheral frameL on the other hand, hinders the Due to their design, do not restrict the wearer's freedom of movement and consequently do not cause any discomfort. This is due to the narrowing of one end and the difference in length of the corresponding insert parts made of absorbent material of the entire absorbent insert thus achieved the sanitary napkin according to the invention adapts well to the body shape and none are formed on the body of the wearer protruding edges or sections. Due to the trough-like, liquid-impermeable design of the bottom lying part of the bandage with the help of the liquid-tight layer it is possible to use the lighter and more pliable To use fleece-like material as a cover or shell, since there is no risk that this is soaked through. This material offers the advantage of reducing the risk of skin inflammation abrasion is prevented and it is softer, avoids wrinkling and thus allows

medium ensures that the liquid-tight tub-like part is always in the area when the bandage is put on selected position remains. Due to the very simple structure of the bandage, the manufacturing costs be lowered.

The invention is explained in more detail below with reference to the drawings and training examples.

F i g. 1 shows a longitudinal section of the sanitary napkin according to the invention;

F i g. Fig. 2 is a cross-sectional view taken along line XX of the sanitary napkin;

F i g. 3 shows a schematic view of a section of the sanitary napkin with a narrowing end;

F i g. 4 shows a further schematic view of a partial section of the sanitary napkin according to the invention and

F i g. 5 shows a further preferred embodiment of the sanitary napkin according to the invention in schematic form View, with symmetrically arranged constrictions adapted according to the legs are.

The cover, made of the so-called "non-woven material", which completely covers the absorbent pad encased, has a continuous surface or a cellular structure, the edges of which are glued or sewing are connected so that the shell is continuous in itself and completely encloses the insert.

The absorbent pad becomes narrower at one or both ends. On the intermediate piece, the corresponds to the part of the body on the thigh, preferably two symmetrical arc-shaped Be arranged recesses.

The absorbent insert parts that form the absorbent insert are at their ends near the shortened impermeable protective layer.

To prevent the bandage from slipping in relation to the underwear, there is at least one adhesive strip made of plastic, which is covered with a protective layer, provided. This tape or the adhesive layer is located directly on the cover of the sanitary napkin and is covered with a protective layer.

Preferred forms of training and their dimensions are as follows:

The absorbent pad contains two absorbent pad parts made of absorbent material, such as. B.

Cellulose pulp and its dimension is between 140 χ 55 mm and 240 χ 110 mm, preferably between 160 χ 67 mm and 220 χ 10 mm.

The length of the absorbent pad parts are in the Faiie that one of A ^agete:! E is short. between 120 and 140 mm for the shorter insert part and 150 to 170 mm for the longer insert part, and can preferably also be 130 or 160 mm long.

In the event that one of the ends of the absorbent pad becomes narrower, the rounding takes place in the tub-like shape over a length of 75 to 105 mm and is at the end up to 55% of the width of the absorbent Inlay. The cohesive layer that at least partially encloses the absorbent pad, consists of a so-called non-woven material, which consists of cellulose fibers ^ textile fibers or whose mixtures are made.

The impermeable protective layer consists of a plastic film with a thickness of 0.01 to 0.03 mm, the dimensions of which are between UO 500 mm and 240 χ UO mm, preferably between 160 χ 67 mm and 220 χ 100 mm.

The connecting layer in between consists of cellulose wadding.

The shell made of the so-called "non-woven material", which completely envelops the insert, consists of Cellulose fibers, textile fibers or their mixtures.

As a connection of the cohesive layer of the impermeable protective layer with the shell Adhesive or stitching may be provided.

The adhesive strip, which ensures that the sanitary napkin remains in its position once put on, can be a be double-sided adhesive tape, which is covered on its outer surface with a protective film, or a liquid adhesive can be applied to the shell with an extruder, with the outer layer the adhesive is protected with a paper film.

In the figures, 1 and Γ denote absorbent insert parts, which represent the absorbent pad, 2 means the intermediate tie layer, the Has paraffin stains, 3 means the double folded cohesive layer that makes up the absorbent Insert wrapped in the longitudinal direction, 4 means the impermeable protective layer, 5 means double Holding layer, which is connected to the layer 3 and the layer 4, 6 means the shell made of the so-called "Non-woven" material, which completely envelops the insert, 7 means the adhesive strip and 8 means the Lines along which layers 3 and 5 are connected.

The arrangement of the absorbent pad, which consists of two pad parts made of an absorbent material and an intermediate tie layer allows the liner to retain its shape and prevents it from breaking once it is soggy

The intermediate connecting layer 2 has the advantage that it allows the uniform distribution of the by the insert part ί absorbed liquids in the insert part 1 'ensures. The paraffin stains on its surface force the liquids that are not absorbed by the direct route into the second Einlageteii 1 'can penetrate, in the direction of the areas of the intermediate connecting layer that have remained hydrophilic to go. In this way, the liquids saturate the entirety of the absorbent ones Deposit evenly.

The layer made of the so-called "non-woven" material that completely envelops the absorbent pad, Its texture reduces the risk of skin inflammation.

The dimensioning of the sanitary napkin according to the invention can also have a meaning, since a Bandage of large dimensions on the one hand ensures a greater absorption capacity of the Fiubsigkciieii and on the other hand the conditions of tightness of the whole are improved. The dangers that they absorbed Liquids leaking into underwear, clothes or the bed are therefore reduced.

The large-sized sanitary towels as shown schematically in FIGS. 4 and 5 are reproduced, can advantageously during the night or in the case of very heavy menstrual bleeding be used. During the day and in the event that the outflows are not very strong, one can get out of aesthetic and for convenience, use an embodiment which is smaller in size and a has a narrowing end; as shown schematically in FIG. 3 reproduced.

According to the embodiment of the sanitary napkin according to the invention shown in FIG. 5 is reproduced, the symmetrical incisions that correspond to the space between the legs improve the tightness of the Sanitary napkin, as the sanitary napkin adapts more closely to the shape of the body thanks to these incisions.

The adhesive strip with which the sanitary napkin is provided, once the protective paper film has been removed the sticking of the sanitary napkin to the undergarment, e.g. B. the panties, secure when putting on the bandage, at the same time it remains in this assumed position and cannot slip.

The impermeable protective layer (4) serves as a barrier that prevents the absorbent pad from getting through to pass absorbed liquids and e.g. B. penetrate into the underwear.
