Tanpon applicator

The invention relates more preferably to Tanipon applicators Made of a material that is dispersible for V7asser, for example cardboard or cardboard, to hold Menstrual tampons.

Tampon applicators are well known, with a outer tubular portion and an inner tubular portion while maintaining a sliding or sliding fit Are composed telescopically. The tampon is received within the outer tubular section, and the inner tubular portion serves as a pusher for pushing out the tampon.

In previously known designs, the sliding fit is between the two sections with the help of wart-shaped deformations maintained in the outer section, which are not

are strong enough to maintain the correct mutual position of the two parts, or with the help of circumferential provided webs which are difficult to manufacture and which lead to restrictions in terms of removal drive, since in the telescopically pushed together position the webs on the start side have the tendency to have a To form a seal against the fluid passage to the inner surface of the applicator.

The invention provides a tanpon applicator, preferably made of a water-dispersible material, with an outer tubular section and an inner one tubular section, while maintaining a sliding or sliding fit within the outer section is inserted telescopically, the outer section having inwardly or outwardly directed longitudinal ribs, the finger grip sections form between adjacent ribs and the inner longitudinal channels with respect to the inner section to facilitate the lengthways Form passage of fluid during disposal.

In this design, the two sections can be telescopically assembled very closely, i.e. with one elastic contact fit over a significant area of the two parts, trapping air between them Telescopically assembled sections and prevents the flow of fluid between the two parts permitted during disposal. Thus, when removing or throwing away in a water closet, the Applicator assumes the telescopically collapsed position, liquid quickly all parts of the applicator to support the elimination.

The longitudinal ribs also have the advantage of to form appropriate finger grip areas and the object to give an extra strength.

Preferably, the outer section has ribs only at one end region, and the inner section is tubular Section designed block-shaped on the outside at its inner end along a zone that inwardly of the ribs, whereby the two tubular sections can be held together.

The most angular material for this item is As indicated above, cardboard or cardboard, but can also with regard to water-dispersible plastic materials can be used, such as polyvinyl alcohol and polyethylene oxide. Other plastic materials can be used when the removal or elimination of the telescoped parts is not a essential requirement is.

The section with longitudinal ribs is produced simply and easily, for example by folding or Compression if cardboard or /. Cardboard is used, or by molding, injection molding or the like if a plastic mater! al is used.

The following is an embodiment of the invention described by way of example and with reference to the drawing. In this shows:

FIG. 6 shows a partial longitudinal section through a second composite applicator and

FIG. 7 shows a section along the line VII-VII in FIG. 6.

Figures 1, 2 and 3 each show a perspective view of an outer tubular section which is made to do so is to form an applicator with an inner section with which it telescopically mates.

Figure 4 shows an outer section 1 as well as that Figures 1, 2 and 3, fitted closely onto an inner section 2 in a telescopically extended position is. A tampon 3 and a retraction tape 4 are arranged within the two parts of this applicator. Of the outer section 1 has longitudinal ribs 5 (in Figure 1 three ribs, in Figure 2 four ribs and in Figure 3 are the Ribs diverging at their ends).

According to FIG. 5, these longitudinal ribs 5 together with the wall of the inner section 2 has a longitudinal gap 6. Each such gap 6 allows the fluid to flow through between the telescopically assembled parts into the inner areas of the applicator while its disposal or destruction in a Viasserklosett or a chemical toilet, whereby the entire cardboard or cardboard material are quickly moistened with a view to favoring its destruction can. The lack of air within the parts reduces their buoyancy or buoyancy and supports this Flush away in a water closet.

The outer section 1 is equipped at its end with longitudinal webs 5, which by folding, dipping or im lie of injection molding are made. Thus three or four radially arranged jaws push inwards to the areas between the longitudinal ribs 5 against a corresponding

809824/0898

Speaking designed inner core to press temporarily inserted within section 1.

The special design of the ends just mentioned leads not only to longitudinal channels 6, but also to suitable finger grip sections 7. In addition, there is a close touching fit on the interior of these finger grip sections 7 with the exterior of the inner portion 2 over a substantial area. This leads to a larger contact area than with most previously known applicators and consequently a stiffer training. The longitudinal ribs contribute to ensuring an exact, cushioned, firm or tight fit, since every small change in dimensions due to twisting or bending is relative to the longitudinal ribs 5 aufger.cu.Tien is.

It can be seen from FIG. 4 that the inner end of the inner section 2 is designed in the shape of a bell towards the outside ends inside the outer section 1 so as to ensure that it comes out of the outer section 1 before the Use cannot fall out. The opposite end of the outer section 1 is also drawn slightly inwards designed to ensure that the tampon is properly held in place and to be comfortable Improve introduction (compared to traditional tampons with sharp edges).

An additional feature may possibly be with the inner section 2 are provided. This consists in having the inner end of this section 2 facing inward to make something bell-shaped or to equip it with an inwardly directed indentation or depression. This avoids any risk of jamming between the tampon 3 and the insertion part.

A second embodiment is shown in FIGS. 6 and 7 shown. In this case, the outer section 1 has an upset end basically similar to that of Figure 3, but with a slightly deeper

8 03 §2.4 / 0898

measured the inward compression, being the end of the outer section 1 is widened outward in a bell-shaped manner in a zone 8. Thus, the finger grip sections have 7 has a more concave shape, i.e. one that more closely conforms to the shape of the fingers. There is another feature of this embodiment in that the inner section 2 is also slightly upset inward, so as to be somewhat square Provide shape (Figure 7), leading to a more orderly arrangement of the unit in the telescopically expanded Position leads. This also makes the manufacture of the tampon applicator with the help of automatic ll machines are supported, as the upsetting is carried out after the two parts have been joined can, in a single operation. This measure also reduces the risk of trapping.

In the examples described above, the ribs 5 extend on the outside of the outer section 1 alternate embodiment extend the ribs inside, in which case they form the bearing surface for the inner section and those between them Zones form the channels for the flow of liquid.
