Abstract

A throw-away sanitary towel has an absorbent element (3) of rayon fluff, a layer (1) of non-woven polyester fibres, permeable to body fluid, on the side towards the body, and an impermeable layer (2) on the rear, made of PE foil. Elastic elements (6,6') are incorporated in the edges (4,5). At least one compression line (10, 11,12a-d,13a+b) of 2-8 cm length and 1.5-5 mm width is arranged parallel to the rim (9.9') of the element (3). ADVANTAGE - This ensures that the pressure exerted by the thighs of the user produces an upturn of the centre, creating additional space for the absorption of body fluid; the edges (4,5) form a good seal of the perineal area and prevent any side leakage.

Description

The invention relates to disposable sanitary napkins or -Inlays that have a higher guarantee of tightness and in particular more effective contact with the Have outer surfaces of the perineal area of a user, increasing the risk of leakage on the sides of the pro product is reduced.

For the purposes of the invention, sanitary napkins are in particular absorbent agent outside the female body to be used, generally during the men structuring time to the monthly flow and other vaginal absorb and retain liquids.

Disposable sanitary napkins are designed to the absorption of fluids from the female body, thrown away without being used again.

Sanitary napkins are articles of general consumption in modern society and can be divided into three categories, for example:
Tampons,
Sanitary napkins, and
Hybrid bandages that have the properties of others
have both types.

Tampons are deposits that flow within the month Vagina can take without the clothes of the user  be soiled. They are considered to be the best in protection viewed tel. In practice, malfunctions can occur their application occur regarding their property themselves when absorbing liquid, expand radially so that due to the expansion of the tampon the vaginal canal seals and closes. There are also women who no tampons for physical or psychological reasons can be used as effective female protective measures nen. Finally, tampons can be introductory and Cause withdrawal problems; occasionally they are sticky and difficult to use, and for health reasons their use is in some cases subject to medical Limitations.

The so-called hybrid bandages have properties of Tam pons and external sanitary napkins. Ge occasionally they become insoles or labial pillows, atrial Called deposits, being a partial or complete Introduced into the vaginal atrium.

In many cases described in the literature, this will be anatomical interaction of the insert with the body of the User not considered in that the sens skin tissue often due to the obstructive geometry certain structural elements are expanded, i.e. the so-called called labial pillows rub on very sensitive urogeni valley areas, such as the vaginal opening, the urethral opening and / or the clitoris. In other cases, it is necessary that a bandage with an area within the Schei denvorhofs is firmly attached to the intimate clothing of the user is attached, and in most cases this leads to a friction effect within this sensitive area.

Thus, according to US-A 20 92 342 and 39 05 372, an element physically to an external one within the vaginal opening Part bound so that the relative movements between the Body of the user and the underlying structure the insert causes discomfort, irritation and even pain  stuff. Similarly, US-A 39 83 873 Side parts or rags described that are against the Lay the walls of the labial space around the holding forces of the bandage to increase. There are other atrial deposits like that are designed that the stimulus factors by the relative Movements of the body and the product and clothes of the Eliminate user (e.g. as described in US-A 47 42 245 ben); however, this product is extremely demanding full and expensive to manufacture.

Bandages have also been used outside the body near the vulva area to record the monthly river other vaginal fluids and possibly urine developed in incontinent women.

In their simplest and most common form, these indicate a lay or bind an absorbent core between one liquid permeable layer or film on the front the side (sometimes referred to as the "upper class") and a liquid impervious backing.

The absorbent core, sometimes called "absorb of the element "is designed so that it the Monthly flow and other vaginal fluids and absorbed. The absorbent core can be shredded cells synthetic fibers, polymer foams, plant pulp, natural Liche or synthetic fibers or another material contain that the monthly rivers or other body fluid can absorb. Generally, pulp as the main component of the absorbent core of bandages to be used outside.

The liquid-permeable top layer lies on the body the user when the bandage is used and leaves the monthly flow or other vaginal fluids, so that they are from the underlying absorbent core can be absorbed. This upper class is in general mean a liquid-permeable, non-woven fabric  or a perforated plastic film. Although the waiter layer can be hydrophilic, it is preferably hydro phob. In this case the monthly flow or others go Liquids through the liquid-permeable upper shifts through, but the upper class feels that they are Is hydrophobic, dry to the product when used makes it more pleasant. The perforated plastic films are generally hydrophobic per se. Non-woven fabrics can, if they are not made of hydrophobic fibers, by Treatment with, for example, a water-repellent Finishing, such as fluorine-containing chemicals or waxes emulsions can be made hydrophobic.

The liquid impermeable backing layer prevents the liquid accumulated by the absorbent core the hygienic bandage flows out and the clothes of the User dirty. The backing is general a thin plastic film, like polyethylene, even though it is in may also consist of other material in some cases, for example a non-woven fabric that treats like this that it is impermeable to liquids. Give Otherwise the back can be permeable to water vapor be, i.e. it can let water vapor through and at the same time be impermeable to liquids.

Expiration, and the most common is the expiration of monthly blood on the sides, is very uncomfortable and embarrassing for the user even in very small amounts. Therefore, when developing such products, it was the aim of the person skilled in the art to maximize the liquid flow in the direction Z (taking into account that in a three-dimensional representation the axes X and Y represent the horizontal plane and the axis Z is directed perpendicular to this plane) . In addition to the technical reasons that justify this goal, there are psychological reasons for the goal that a rapid drain in the Z direction minimizes discoloration on the bandage and, together with a relatively dry top layer, increases the feeling of security and that on failure the bandage, for example embarrassment caused by leaks, is reduced.

The conventional bandage is a very ordinary, elongated ches rectangular product that without regard to the Ana tomie the user has been created. That is, at the Application can deform this product, causing the Absorbance significantly decreased and occurrence be favored by leakage.

There have been many improvements starting from this product made that directly or indirectly to a higher Tightness led:

• - The absorbent layers are more anatomical than one Rectangle, for example in the form of an hourglass poses;
• - The bandage as a whole was given a shell shape in order a better fit between the user's legs to get closer to their perineal area;
• - Upper layers were used, the flow optimize the liquid to the absorbent element and their backflow in the opposite direction prevent;
• - more complicated structures have been developed at for example, an absorbent element, which in its Middle area is thicker around the drainage point and the Bandage to bring each other closer, side tabs that Form drainage barriers, or overlapping structures, as described for example in US-A 44 25 130;
• - The absorbency has been increased, for example by using either absorbent fibers or superabsorbent polymers, by changing the density within and along the conventional, absorbent layer or by using Layers of different materials, etc.

From this list of improvements it can be seen that optimizing the product of this increasingly complicated, more demanding and expensive in relation to the groove achieved zen does what in turn the price for the end user elevated.

When examining the reasons for the appearance of Leakage in sanitary napkins was found to be the way of the vaginal drainage to the point where it meets the Pro product that absorbs and retains such liquids, meets, must be kept as short as possible. The is also shown by the fact that every distance is liquid speed allows more or less about the drain make neighboring skin flow, which in turn, for example of the viscosity and surface tension of a depends on such liquid. In some cases, the Absorb liquid even out of reach drain the layer and so discomfort, embarrassment and the feeling of insecurity for the user. This leads to the conclusion that a structure with one recorded performance, what absorption and liquid sustainability concerns only from the moment can be achieved in which the liquid with a sol structure comes into contact and not before.

The object of the invention is therefore to overcome the disadvantages of To overcome the state of the art and a disposable To provide sanitary napkin, which is the danger from leakage on the sides effectively reduced without new materials and complicated and sophisticated structure doors that are difficult to manufacture, as well as simple and effective and an inexpensive Has cost-benefit ratio.

The invention solves this problem with a disposable Sanitary napkin, which is characterized by at least one line obtainable by compression along or in the Near each longitudinal edge of the bandage. These lines are enough  far enough away from each other, so that by the Thigh of the user exerted pressure on the product forms a protuberance towards the body of the user, in which can drain the liquids.

The function of the bandage according to the invention is based on the Fact that when using the product its middle range is compressed by the thigh of the user. By this densification becomes the material between the two Lines pressed towards the user's body, creating more Drainage absorption material available supply, i.e. where the absorption requirement is greatest is. In this way, the liquid flows freely with the ability to escape through the skin prevents and thus reduces the risk of leakage.

As in the prior art, the two lines are not present, the absorbent material can be under the user's thigh pressure away from the body or assume a random configuration that has no particular brings its contact at the drainage point.

That is, unlike conventional sanitary napkins that are gone throwable sanitary napkin according to the invention a protuberance of the absorbent material allows for contact with optimize the body of the user without additional ches absorbent material used for this purpose must become.

The expression "compaction line" or "Line obtained by compression" means that the Kör such a pressure along the hygiene bandage Line is subjected to that in an inelastic way higher density than the surrounding material is obtained. Such lines - there must be at least two of them that can be straight or not straight as well as to each other and be parallel to the longitudinal edges, they can also be any Have depth. The lines preferably run to the  Longitudinal edges parallel, their width is less than 5 mm because this way they form the protuberance favor if the product is used.

A line obtained by high compression is opposite a line by low compression is preferred, because it has the ability of the absorber layer to form the protuberance to the body begin under the pressure of the thigh increases. However, a compression above a certain value has the disadvantage that a line of hard material is created, which in turn can be uncomfortable for the user. A is the only line of compaction along each longitudinal edge prefers. However, two or more neighboring are also suitable beard lines along each longitudinal edge or others Configurations that do not adversely affect the training extension of the protuberance while using the product impact.

The term "longitudinal edge" refers to the edges ent long of the absorbent material of the invention Bandage. This expression does not refer to the longitudinal ranks along the product, which also have side tabs can protrude beyond the absorbent element.

The expression "along or near each longitudinal edge" means the distance from one by compression line obtained to the nearest longitudinal edge is less than the distance between this one line and the other line obtained by compression on the opposite the longitudinal edge. Because the compression lines because of their size are dense areas of preferred liquid conduction, they are not so close to the longitudinal edges that there is a leak danger occurs, but not so close together that prevents the formation of the protuberance given above becomes. The distance between one compression is preferably line to the nearest longitudinal edge about 5 to 30%, esp  especially about 5 to 20% of the width of the absorbent ele mentions.

The distance between the compaction lines also depends on the material or materials that make up the absorbent material form and, for example, different elasticity, Can have density or fiber length. A specific one The property of the compaction lines is that they are preferred Represent drainage paths for liquids, and therefore the Guide leaked liquid to areas or wicks suck in, which are further away from the drainage point, i.e. they distribute the liquid more homogeneously and faster over the whole absorbent element so that the liquid less time is available with the skin of the User come into contact, and a leak is avoided the one that would occur if there was a lot of menstrual flow liquid in a single place without compression lines drains for easier distribution.

More conventional in some practical embodiments Sanitary napkins become elastic means in combination with Side tabs along the product and a layer of cotton wool Pulp fibers used as an absorbent element. It should be noted that a certain compression of the absorbent element during storage of the product occurs. These elastic means give the product anato mix curvatures and folds, and the elasticity of the Pulp fibers allow this to prefer to get close embed the anatomical curvatures and folds so that they undesirable areas of higher density and consequently lower absorption rate, usually at the Give way of the menstrual drain. The Verdich lines give the cellulose wadding cohesion and therefore Resistance to elastic movements of your Fibers in places favorable to the product, e.g. along of the longitudinal edges where they contain the leaked liquid lead more distant areas of the absorbent member  and the above protuberance when using the bandage can bring about.

The "body" of the bandage means here that this comprises at least the absorbent element and against can also consist of other layers, e.g. the top layer and the back layer that are on, under or in the body are arranged. The compaction lines can thus possibly only in the absorbent element or into any other structural element that the body of the bandage contains, to be pressed. For example, the Density lines both in the upper layer and in the absorbent element are produced.

The preferred method of making the compaction lines is that on the absorbent body Relief pattern from a corresponding material and the desired shape is applied and pressed, so that Material of the absorbent element is sufficiently embossed, if necessary by hot pressing to create compaction lines to call. The one brought into contact with the relief pattern The surface of the absorbent element is that of the body the side facing the user; in the other case, the pressure exerted by the user's thighs unfavorable formation of the protuberance on that side of the absorbent element facing away from the body.

An example of large-scale production of the inventions The bandage according to the invention consists in the extent of a To apply a number of identical relief patterns to the rotary cylinder and the wadding constituting the absorbent member between this cylinder and a conveyor belt under sufficient Apply pressure to the compaction lines on the wat to manufacture.

The disposable sanitary napkin according to the invention is not limited to a special type of structure and can do the following Features:  

• - Liquid-permeable cover layers from a not woven fabric or perforated plastic film, with or without embossing, alone or in combination with other materials, with either hydrophobic or hydrophilic or other properties,
• - a single-layer or multi-layer layer of wood or other plant pulp, polymer or natural chem foam, hydrophobic fibers, either alone or mixed together, the superabsorbent Polymers with areas of different density point,
• - If necessary, means for attaching the bandage to the Clothing of the user,
• - an outer backing of either whole or part wise hydrophobic material or materials, breathable active or not, as a single or multiple shift,
• - if necessary, elastic means,
• - in a rectangular shape, in the form of an hourglass or any other appropriate form.

The compaction lines must be close to the longitudinal edges of the Range, which should take up the monthly flow, and should be a length of preferably about 1 to 12 cm and in particular have about 2 to 8 cm.

In a preferred embodiment of the invention that the compaction lines not only run along the Longitudinal edges, but extend complementarily into the Areas that do not directly record the monthly flow, son rather, it has a direction leading to each other sen until they meet and continue in both directions to be led. This will make it faster and more homogeneous Distribution of the rivers collected in the absorbent element optimized.

However, the invention also relates to embodiments in where the compression lines do not meet or radial  are divided, or also embodiments that the ge collected liquid to distribute without the ability to Protuberance between the compaction lines under the top to form thigh pressure of the user influence.

In the drawing, an externally applicable hygiene bandage 30 elongated shape with rounded upper and lower ends 16 and 17 is shown. It consists of a liquid-permeable top layer 1 , an absorbent element or core 3 and a liquid-impermeable backing layer 2 . The bandage 30 also includes a pair of elastic elements 6 , 6 ', which are located on the longitudinally extending side edges 18 and 19 of the bandage. The bandage 30 has compression lines (compression lines) 10 , 11 , 12 a , 12 b , 12 c , 12 d , 13 a and 13 b , which are explained in more detail below. From Fig. 1b z. B. can be seen that the top layer 1 and the back layer 2 extend over the same width. Layers 1 and 2 are also the same length. In contrast, the length of the absorbent element 3 is less than the length of the top and back layers and its width is less than the width of the top and back layers. The absorbent member 3 has a pair of longitudinally extending side edges 9 , 9 ', a rounded upper edge 21 and a rounded lower edge 22 , which together form the periphery of the absorbent member. The absorbent element is located between the top layer 1 and the back layer 2 , as can best be seen from FIG. 1b. The top layer 1 and the backing layer 2 are fastened to one another at the edge parts, for example by heat sealing, that is to say to those parts which lie between the circumference of the absorbent element 3 and the circumference of the bandage 30 , through the mentioned upper edge 16 , the lower edge 17 and the layers 1 and 2 , which are fastened to one another in the manner indicated, are formed by longitudinally extending sides tabs 4 , 5 in the bandage 30 .

Between the top layer 1 and the back layer 2 there are elastic elements 6 , 6 'in the longitudinal tabs 4 , 5 of the bandage 30 . These elastic elements are in a stretched but elastically contractible state when the bandage 30 is spread out flat, as in FIG. 1a. When the elastic elements contract from their stretched state, the bandage assumes a "boat-like" shape according to FIG. 2a. The elastic elements can be one or more rubber monofilaments which are fastened, for example, by means of a hot-melt adhesive between the top layer and the back layer according to FIG. 1b. Preferably, however, a strip of a thermoplastic film that contracts and becomes elastic after heat treatment is used as the elastic member. Various heat-shrinkable thermoplastic films which have elastic properties after heat shrinking are known. Strips of a heat-shrinkable ethylene and vinyl acetate copolymer having a basis weight of about 35 g / cm ² , a length of about 13 cm, a width of about 1 cm and a thickness of about 30 μm are preferably used according to the invention.

The elastic members are preferably about 60% of the length of the bandage 30 and are centered from one end to the other of the bandage. The indicated strips of heat-shrinkable copolymer are attached in their relaxed state between the top and back layers using an arrangement for heat sealing, whereby a series of spaced, transversely oriented attachment lines 7 is formed ( Fig. 1a). The fastening lines 7 are separated from one another by areas 8 in which there is no seal. If the heat-shrinkable elastic elements 6 are fastened between the top layer and the back layer by the above-mentioned heat sealing, the elements 6 , 6 'contract under the action of the applied heat and thereby obtain their elastic properties. If the heat-shrinkable elastic elements 6 , 6 'are fastened, for example, with an adhesive, the elements must then be treated with heat, for example hot air, so that they contract and maintain their elastic properties. Are the elastic elements 6 , 6 'in the contracted state, the bandage 30 assumes the anatomical, shell-shaped configuration according to FIGS. 2a and 2b. The side tabs 4 , 5 and their adjacent areas of the napkin are raised upwards, as shown in FIG. 2b, so that the tabs form an angle of approximately 30 ° with the horizontal plane 36 of the napkin 30 in the expanded state according to FIG. 1b.

Preferably, the liquid-permeable top layer 1 consists of a non-woven fabric made of heat-sealable polyester fibers with a basis weight of 22 g / m with 144 perforations per 6.45 cm ² (square inch). The liquid impermeable layer 2 preferably consists of a polyethylene film with a basis weight of 19 g / cm ² and a thickness of about 0.020 mm. If the top layer 1 consists of heat-sealable polyester fibers and the back layer 2 of polyethylene, the top layer and the back layer can be sealed at their edge parts by heat. In a preferred embodiment, the absorbent element 3 consists of a layer of 100% fleece wool with a weight of about 7 g. In a typical hygiene sanitary napkin 3 is about 20 cm long and about 6 cm wide. The absorbent element 3 is located in a known manner between the liquid-permeable top layer 1 and the liquid-impermeable back layer 2 .

In one embodiment of the invention, the hygiene bandage 30 has a first pair of compression lines 10 , 11 which run parallel to the longitudinally extending side edges 9 , 9 'of the absorbent element 3 . For a sanitary napkin 30 with a length of 22 cm, compaction lines 10 , 11 are about 6 cm long (between points A and B and A 'and B ' in Fig. 1a) and somewhat inward at a distance (about 0.8 cm ) arranged from the longitudinal side edges 9 , 9 'of the absorbent element 3 . The Verdichtungli lines 10 , 11 are arranged substantially in the middle between the upper and lower edges of the napkin.

In a second and more preferred embodiment of the invention, the sanitary napkin 30 has four further sealing lines. As shown in Fig. 1a, a pair of compaction lines extends at an angle from the ends of each compaction line 10 , 11 to points ( C and C ' in Fig. 1a), which lie on the longitudinal center line 33 of the sanitary napkin 30 . So at the upper end of the bandage 30 runs a third line of compression 12 a from the upper end A 'of the first line of compaction 10 to a first point C on the center line 33 between the end A and the upper edge 16 of the bandage.

Accordingly, a fourth compression line 12 b extends from the upper end A of the second compression line 11 to the first point C. A second pair of angularly arranged compression lines 12 c and 12 d is located near the lower part of the sanitary napkin. A fifth line of compaction line 12 c extends from the lower end B 'of the first sealing line 10 to a second point C' on the center line 33 between the end B 'and the lower edge 17 of the bandage 30 . A sixth compression line 12 d runs from the lower end B of the second compression line 11 to the second point C ' on the center line 33 .

If the compression lines 10 , 11 , 12 a , 12 b , 12 c and 12 d are arranged in the manner just described, they form an elongated hexagonal configuration, as shown in FIG. 1a.

From Fig. La it can also be seen that the first compression line 10 and the second compression line 11 parallel to each other and to the side edges 9 , 9 'of the absorb the element 3 . In a typical sanitary napkin 30 with a length of approximately 22 cm and a width of approximately 8 cm, which has an absorbent element 3 with a length of approximately 20 cm and a width of approximately 6 cm, the compression lines 10 and 11 have a length of about 6 cm and a width of about 0.15 cm. The compression lines 10 and 11 are expediently at a distance of approximately 4 cm.

In another embodiment of the invention, the sanitary napkin has a further pair of compaction lines along the longitudinal center line 33 . From Fig. 1a it can be seen that a seventh compression line 13 a runs from point C to point D on the longitudinal center line 33 in the direction of the upper end of the sanitary napkin. Correspondingly, an eighth compression line 13 d runs from point C ' to point D' on the longitudinal center line 33 in the direction of the lower end of the sanitary napkin. If the bandage 30 and the compression lines 10 , 11 , 12 a , 12 b , 12 c and 12 d have the typical lengths indicated, the compression lines 13 a and 13 b are expediently 1.5 cm long. It will be apparent to a person skilled in the art that the various dimensions given here for the bandage 30 , the absorbent element 3 and the various compression lines are only examples and that these dimensions can be changed.

A steel plate can be used to form the compaction lines with ribs that match the desired compaction line pattern correspond to be used. For example, that absorbent element on a fixed surface pla adorned and then covered with the steel plate, so that their ribs with the top of the absorbent element come into contact. The steel plate is then against that absorbent element pressed, being a hydraulic Press (Norgren) with a pressure of 630 mbar (9 psi) Formation of compaction lines is used.

Fig. 3 shows the bandage of Fig. 2 in use, brought into the perineal area 40 of the user. Under the pressure of the user's thighs 12 and 13 , the protuberance 14 forms between the compression lines 10 and 11 . The flaps 4 and 5 lie against the thighs of the user and thus effectively prevent lateral leakage.

Fig. 4 shows three examples of th compaction lines arranged according to the invention. In Fig. 4a, the sealing lines do not meet; in Fig. 4b the compaction lines meet and diverge radially to the outermost regions of the napkin; in Fig. 4c, two lines of compaction are arranged along each longitudinal edge.

The sanitary napkin according to the invention shown in FIG. 2 was investigated in a group of 17 women.

Each woman received 7 sanitary napkins according to the invention, i. H. with ver sealing lines (hereinafter referred to as group A bandages  net) as well as 7 other bandages corresponding to these bandages, however without the compression lines (in the following with group B-bandages).

Each woman wore the bandages during menstruation, using the group A and B bandages alternately. Each bandage was used for an average of four hours.

After use, each bandage was on the formation of the Aus in the middle and the occurrence of leakage examined the pages. The following results were obtained receive:

• - 40% more bandages from group A than group B showed the formation of the protuberance in the middle, whereby it is proven that the use of compaction lines leads to the formation of this protuberance.
• 5% less bandages from group A than group B showed signs of leakage on the sides, from which it can be seen that the protuberance according to the invention near the outflow point helps to prevent leakage.
