The invention relates to a menstrual swab consisting of at least one strip of liquid-absorbent material, which strip is wrapped essentially around itself into a tampon blank and then radially compressed into the final shape of the tampon, in which the tampon is fitted with a thread for removing the tampon.

When using such tampons, they usually need to be provided with an removal wire to remove the tampon from the body orifice after use. Such tampons are characterized by a high swelling capacity and, as a result, a high suction power, so they have won the field well in practice. A nonwoven mat consisting of natural fibers, preferably cotton and sometimes staple fiber, is generally used as the liquid-absorbent material, as well as an additional blend of man-made fibers when the opportunity arises. Although the collapsed state of the fibers gives such a nonwoven mat a certain strength, the individual fibers nevertheless run mainly in the longitudinal direction of the web strip. As a result, the fibers run approximately parallel to the longitudinal sides and the outer surface of the web strip relative to them, while the ends of the fibers form the ends of the web strip. Such web strips have hitherto been wound on a roll either from one end to the other end, as described, for example, in German Patent Publication No. 2,547,835, or by the winding fork gripping the strip from outside the longitudinal center across it so that the distance between the ends of the carpet strip dimensioned for separation and only one of the ends of the strip has to be finished on the outer surface of the roll (German Patent Publication No. 915,382). In this case, the aim is in each case that the discharge thread is placed in the tampon as close to the longitudinal center as possible so that the forces in it are applied to the tampon material.

The object of the invention is to improve the type of tampon already mentioned in the sense that by maintaining good swelling and suction power, increased safety is guaranteed as well as strong cohesiveness of the tampon.

This object is solved by a tampon according to the invention, which is characterized mainly by the fact that the blank is formed by wrapping a strip on the roll at least at both ends towards its longitudinal center, and that both strip ends are alternatively wrapped in the same direction or in opposite directions.

A second embodiment can be derived from this by providing a second roll by wrapping the middle length of the strip on the roll. This can improve the balance of the tampon, because in each case when the tampon is removed from the body opening when it is unilaterally loaded, the interconnected rollers of the carpet strips can support each other.

The direction of rotation of the winding direction of the ends of both strips may optionally be opposite or parallel.

For the reason that radial compression provides a cylindrical shape, it is recommended to dimension the diameters of the billet rolls to be approximately equal. However, when the situation arises, the diameters of the rollers may also be dimensioned to different sizes.

According to another embodiment, the axes of the rollers may be in the same plane. This is advantageous in that it makes it possible to adapt the construction of the tampon, regardless of the quality of the compression, to the cross-sectional shape of the opening of the female body.

In another embodiment, the tampon may be provided with a simple ejection yarn so that portions of the simple ejection yarn pass through rollers having the ends of the yarn joined together at the pull-out end of the tampon, for example by a knot or loop. The discharge wire may be a double pan discharge wire, 3,5208 with a loop located at the discharge end of the tampon and extending approximately through the longitudinal axis of one roll, the free ends being led back from the insert of the tampon back through the discharge end to at least the other roll.

If a double-folded discharge yarn is used in connection with a tampon consisting of three rolls, a second embodiment can be derived therefrom so that the double-folded discharge yarn passes through the middle roll and each free end of the discharge yarn from the insertion ends is passed back to the discharge end of each other roll. The free ends are preferably returned to the outlet end by means of a loop. Thus, a particularly high production speed can be achieved. In addition, there is also the possibility of tying the ends of the discharge wire to each other at the discharge end. Each of the above-mentioned methods of attaching the discharge yarn offers the advantage that the rollers are not only bonded to each other by means of a mat strip, but also by the release thread itself, so that the tampon is held together without compromising the expansion and suction power.

In the drawings, exemplary embodiments of the invention are shown by way of example and schematic diagrams. They present:

Figures 1-8 show the blanks of different embodiments in a perspective view and Figure 9 shows one of the blanks made according to Figures 1-8 in a radially compressed tampon, as well as a perspective view.

Figure 9 shows a women's tampon 1 consisting of at least one strip of liquid-absorbent material, which is mainly wrapped around a roll into a blank and radially tightly compressed into one final tampon shape. When the opportunity arises, it is also possible to use insignificant axial compression, where, by way of example, the tampon insertion head rotates.

Figures 1-8 illustrate blanks for such a tampon. According to the invention, these blanks are formed by wrapping on a roll a strip of liquid-absorbent material, e.g. a wadding mat, consisting of pulsed natural and / or man-made fibers and formed at least at both ends in the direction of their longitudinal center.

In the embodiment according to Figure 1, such a carpet strip is denoted by the number 2, both ends of which are wound on a roll on one side of the longitudinal center of the carpet strip in an opposite position 4 57208 relative to each other. The direction of rotation of the winding direction of the two rollers 2a, 2b is directed in the opposite direction, so that the middle mat part 2c connects the two rollers to each other in a tangential plane superimposed thereon. The axes of each roll are parallel to each other and are located in a plane parallel to the distance from the outermost central carpet strip 2c.

The double-applied removal thread 3 protrudes in a loop 3a from one end of the roll 2a to form part of the tampon removal thread. The double discharge thread 3 is returned through the longitudinal center of the roll 2a, forming a U-shaped loop 3b at the front sides of each roll 2a, 2b on the opposite side formed by the tampon insert end of the tampon. Each of the wire ends 3c, 3d hanging from the roll 2b is passed through the loop 3a so that the discharge wire itself is fixedly anchored and, in addition, keeps each roll 2a, 2b side by side in their mutually contacting state.

The embodiment of the blank according to Fig. 2 differs from the blank of the embodiment according to Fig. 1 only in that only one yarn of the discharge yarn 4 binds both rolls 2a, 2b in the same way as in the embodiment according to Fig. 1, although the yarn ends 4a, 4b are knotted together in 4c. The knot is formed in such a way that the loop 4d connecting the rollers 2a, 2b leaves sufficient play space for the tampon, after wetting the liquid V) i, to expand into the preform shape shown in Fig. 2.

Figure 3 shows a blank formed by two parallel rollers 5a, 5b formed by wrapping on each roll each end of one mat strip in the same direction of rotation. The carpet part 5c connecting each roll 5a, 5b thus spreads in an S-shape between each roll. Here, too, as in Fig. 1, both rolls are tied together with a double-paned discharge wire, so that the reference markings and description according to Fig. 1 can be used here.

In Fig. 4, the embodiment of the blank corresponds to the embodiment of the blank according to Fig. 3, so that the same reference numerals are used here. However, the two rollers are connected to each other in the manner of the discharge wire 4 shown in Fig. 2, so that the description has been used according to Fig. 2 and the reference numerals used therein according to Fig. 4.

Figure 5 shows a blank formed of three rollers 6a, 6b and 6c. In all three rollers, the direction of rotation is in the opposite direction of the clock pointer, so that the parts 6d and 6e connecting the rollers to each other, again in cross section, run in an S-shape. The rollers are located in the same parallel plane so that when used, the tampon compressed from this blank can expand into the shape of the blank shown in Figure 5 and can thus advantageously adapt to the cross-section of a woman's body orifice. The middle roll 6b is formed by wrapping on the roll the middle longitudinal part of the carpet strip, e.g. with a rotatable winding fork which grips the strip in the middle. As a result, the inner end 6f of the carpet strip in this roll cross-section illustrates a U-shaped loop.

The other end of the removal wire 7 forms a loop 7a which hangs outwards from the front end of the middle roller 6b for removing the tampon. The doubly inserted discharge yarn 7 is passed through the roll 6b to the insertion end of the roll 6b, whereby connecting both ends 7b, 7c of the discharge wire to form U-shaped loops 7d and 7e is passed through the roll 6a or 6c in the blank discharge direction and through the loop 7. In this way, the free but secure adhesion of all three rolls of the blank is also guaranteed by the discharge thread and by the securing of the discharge thread itself.

There is an embodiment of the blank according to Fig. 6 if the roll 6c according to Fig. 5 is placed on both rollers 6a and 6b so that each of the three rollers contacts the other two rollers, and the rollers 8a, 8b and 8c are arranged in a triangular cross section. This arrangement of rolls may be advantageous for the safety of the compressed tampon. Passing the discharge thread through the spool corresponds to the method shown in Fig. 5, so that the parts concerning the discharge wire are marked with the same reference numerals as in Fig. 5 ·

The embodiment of the blank according to Fig. 7 differs from the embodiment according to Fig. 5 in that the two rollers 9a, 9b are wound in the opposite direction of rotation of the roll, while the roller 9c corresponding to the roller 9a is formed by wrapping on the roll in the opposite direction of rotation. Here, the middle roll 9b, like the middle roll 6b in Fig. 5 and 8b in Fig. 6, is formed by wrapping on the roll the middle longitudinal portion of the carpet strip so that the inner end 9d of the middle roll 9b is cross-sectional to show a loop. The discharge wire 7 connects the rollers 9a, 9b and 9c as in Fig. 5, so that the same reference numerals have been used in this respect. The blank according to Fig. 8 is formed such that the roller 9a in Fig. 7 is placed on each of the rollers 9e and 9c so that, as in Fig. 8, the rollers 10a and 10c are arranged in a triangular cross-section.

The discharge wire 7 is passed in duplicate through the roller 10b, while both ends 7b and 7c thereof are in each case passed back through the roller 10a or 10c and through the loop 7a. This arrangement of the discharge wire again corresponds to the arrangement of the discharge wire according to Figures 5 »6 and 7.

All the blanks of Figures 1-8 can be radially compressed into the final cylindrical shape of the tampon of Figure 9. When the tampon 1 according to Fig. 9 is put into use, this moistened with liquid expands substantially cylindrically. It is obvious that in none of the embodiments shown, the end of the primarily carded webs is located on the outer surface of the blank or tampon, thus preventing the fiber dolls from getting trapped when the tampon is removed from the body orifice. Furthermore, there can be no question of tearing each other when removing tampons made according to the blanks shown in Figures 1-8, because all the rolls are connected to each other using a certain removal yarn without impeding the expansion capacity of the fibrous material.
