Description

The present invention relates to a sanitary napkin which is provided with a large absorption capacity.

There are already a large number of models of sanitary napkins. However, the majority of these models have a limited one Absorbency, and / or they are not sufficiently liquid-tight, which for example on their shape or on the nature of the materials that make them up.

That these qualities prove to be inadequate is made even clearer by the fact that the sanitary napkins are intended for women who have a strong rule and / or are lying down, such as during the night or during a Illness.

So it is especially for a woman when she is a horizontal one Finds it much more difficult to monitor a heavy discharge, especially when she is asleep.

This leads to the questions about the absorption and after fluid resistance is of all importance.

The sanitary napkin according to the invention lends itself to solving these problems in a satisfactory manner.

The sanitary napkin according to the invention is characterized in that it is formed from an absorbent core and an outer, impermeable protective layer, the two Elements are connected to one another and the protective layer is provided on its outer surface with a means which prevents the arrangement from slipping in relation to the underwear.

According to preferred embodiments, the inventive Sanitary napkin characterized by the following features:

The absorbent core is formed from at least two layers of absorbent material which are sandwiched between two tie layers are arranged from tear-resistant material, and it further includes a layer of a material as "not woven or knitted" or as "random fiber fleece" is referred to, which at least partially surrounds it;

the surface of the middle connecting layer is in alternative Training hydrophilic and hydrophobic;

the middle connecting layer of the absorbent core is formed from a cellulose wadding layer, the surface of which Wears stains made of a hydrophobic material such as paraffin;

the absorbent core is attached to the protective layer along its circumference over the middle of the layer of the "non-woven or knitted "material connected;

309881/0502

two symmetrical arched cutouts are made in its central area, which correspond to the inner leg length.

The measure, which should prevent the sanitary napkin from slipping in relation to the underwear, can be implemented by at least one adhesive acting tape are formed, which is attached to the outer surface of the protective layer, or from a layer of a Material that has a high coefficient of friction, such as a cellular material.

According to a further embodiment of the invention · ' The sanitary napkin is narrowed at one end. This end of the sanitary napkin is selected to be between the Legs of the wearer to be placed.

According to a further embodiment of the invention Sanitary napkin is one of the layers of absorbent material that makes up the core, shortened at both ends. Man selects the layer which is shortened at its two ends in such a way that it is adjacent to the outer protective layer comes to rest.

According to a further embodiment of the sanitary napkin according to the invention, of the connecting layers between which the layers of absorbent material are arranged, those which are on the outside, single or multiple be formed, and envelop said layers of absorbent material in the longitudinal direction.

In this embodiment, the connecting layer covers or cover the tie layers which are adjacent to the outer protective layer and which are substantially the same length as that absorbent layers have the ends of the enveloping tie layer or tie layers which are on the opposite side Side are arranged according to their axis.

309881/0502

The opposing connecting layers can be connected to one another, which can be achieved by conventional means, such as, for example, by a. Gluing can be done.

These embodiments of the sanitary napkin enable a further improved attachment of the same to the body, whereby at the same time they lead to a smaller risk that the edges are not visible.

They also ensure better retention of the absorbent core and its larger fit when it is once got wet.

The sanitary napkin according to the invention can according to the following example be constructed:

The outer protective layer consists of an impermeable material, such as a sheet of plastic with a thickness of 0.03 to 0.05 mm. Their dimensions can be between 210 χ 55 mm and 280 χ 110 mm. Preferably it has a size of 230 χ 67 mm and from 260 χ 100 mm.

The absorbent core consists of two layers of absorbent Material such as cellulose, the dimensions of which are between 190 55 mm and 240 χ 110 mm. Preferably amount they are 200 χ β5 mm and 220 χ 100 mm. -

The lengths of the absorbent layers, in the event that one of them is shortened, are between 150 and 170 mm for the shorter and I90 to 210 mm for the longer, being preferred l60 and 200 mm.

In the event that one of the ends of the absorbent core is constricted, this constriction extends progressively over a length of 75 to 105 mm, whereby it can be of the order of magnitude of up to 55 ¹ P of the width at the end.

The layer of a material marked with "not woven or knitted "or referred to as" V / Irrfaservlies ", soft at least partially envelops the absorbent material, is

formed from cellulose fibers, from textile fibers ^ or from compounds the same.

The tie layers are formed from a cotton swab.

The bond between the layer of "non-woven or knitted" material and the outer protective layer is through conventional measures, such as gluing or welding, formed.

The adhesive tapes that ensure that the sanitary napkin is held in place can be tapes be with a double-sided adhesive effect, which are provided with a protective sheet on their outer surface.

The layer of cellular material that serves to hold the assembly in place can be made from a foam plastic, such as a polyurethane foam, exist.

The accompanying drawings serve to further explain the invention without, however, being viewed as a restriction thereof shall be.

In the drawings, the reference numeral 1 denotes the absorbent core. The reference number 2 denotes the outer protective layer made of an impermeable material. The reference number 3 represents the layer made of a hydrophilic “non-woven or knitted” or “random-fiber fleece-like” material which partially envelops the absorbent core 1. The reference numeral 4 indicates the path along which the layer made of a “non-woven or knitted” or “random-fiber fleece-like” material 3 is connected to the outer protective layer 2. The reference number 5 shows the tapes with adhesive action and the reference number 6 a protective paper layer for the tapes with adhesive action 5 " The reference number 7 denotes the lines along which the connecting layers are connected to one another. The reference numbers 1 'and 1" are the absorbent layers which consist of cellulose pulp, while with the reference numerals 1 "', 1"' ^a , I ¹ "" and I ¹ "" ^a the connecting layers of a cotton fabric are identified, which are arranged on the outside of the layers of absorbent material are. Finally, the reference symbol 1 ″ ″ denotes the middle connecting layer made of cotton wool, which can be hydrophilic and hydrophobic in an alternative manner. The layers up to 1 '''' ^f contribute to the formation of the absorbent core.

The plurality of layers of absorbent material and the tie layers that make up the absorbent core prevents the core from breaking once it has become damp.

The middle tie layer l '' ^! 'has the advantage that a uniform distribution of the layers I ¹ and I ¹¹¹

309881/0502

as well as possibly ι ^{Μ | 8-} absorbed liquids which have reached its surface. The paraffin stains attached to the surface ensure that it is alternatively hydrophobic or hydrophilic. They force the liquids, which cannot get into the second absorbent layer 1 ″ in the most direct way, to reach the points of the middle connecting layer ¹¹¹¹ which remain hydrophilic.

In this way, the liquids wet the whole of the absorbent core evenly.

The layer of the "non-woven or knitted" or "random fiber fleece-like" material reduces the risk of a Skin irritation.

The expansion of the sanitary napkin according to the invention plays a role in the same way, since a large sanitary napkin is a has greater capacity for the absorption of liquids on the one hand and because they are the conditions for on the other hand fluid resistance of the assembly improves because it covers a greater part of the body. One therefore finds a reduced risk of absorbed liquids leaking to the linen or to the bed.

The large sanitary napkin is advantageously used during the night. During the day and in the event of a low menstrual period For aesthetic reasons or for practical reasons, one can use a model of the sanitary napkin that has a tapered end having.

In a preferred embodiment of the invention Sanitary napkin is provided with arched cutouts in its central area, which are symmetrical and which inner leg length run accordingly, whereby the fluid resistance of the arrangement is improved, since the Arch-shaped cutouts can better fit the body shape.

When finally the sanitary napkin according to the invention is in place attached, it does not move because it is provided with two adhesive bands which, if the paper protective layer is removed, stick in the underwear, for example in the pants, from the time when the sanitary napkin is attached.

This ensures that no matter what position the wearer assumes, whether she is lying or standing or what movements it also carries out the sanitary napkin cannot slip.

It goes without saying that the invention is not limited to the illustrated embodiment described, rather, it embraces all arrangements based on the same principle.
