Abstract: A tampon having a relatively high density, compressed core and a plurality of lower density longitudinal ribs and a soft outer surface.

Abstract: A process for forming a tampon having a relatively high density, compressed core and a plurality of lower density longitudinal ribs is disclosed. The longitudinal ribs have a softer fiber structure and a coarser capillary structure and extend radially from the core. The process includes forming a fibrous tampon blank, radially pressing a circumferential surface of the blank over spaced apart longitudinally extending portions to form spaced apart ribs, exposing the longitudinal ribs to a radially applied second pressure to form a tampon having a relatively high density, compressed core and a plurality of lower density longitudinal ribs, extending therefrom. The longitudinal ribs are separated one from another by outwardly open longitudinal grooves, at least where they extend from the core, and they form a soft, essentially smoothly cylindrical outer surface of the tampon.

Abstract: The invention relates to a tampon applicator having a cylindrical outer sleeve and an inner sleeve, which is displaceable therein, is provided with an axial longitudinal slit and encloses a tampon. A tongue-shaped retention element is integrally connected to the outer sleeve so as to be bendable and projects through the longitudinal slit of the inner sleeve into the latter, and lies against the rear end of the tampon. When the inner sleeve is withdrawn out of the outer sleeve, the tampon is held in place by the retention element and transferred into the outer sleeve. The retention element is provided with one part of a locking mechanism (detent plate), the other part of which is formed by one of the two sleeves (longitudinal edges of the longitudinal slit of the inner sleeve. The aforesaid locking parts interact in such a way that the retention element is locked in its engaged position bent into the inner sleeve.

Abstract: The invention relates to a tampon (10), to the essentially cylindrical circumferential surface of which a liquid-permeable, thermoplastic material is fastened, with the application of pressure and heat. The dome-like constriction (10b) at the introduction end (10a) and the withdrawal end (10c) of the tampon (10) remain free of the liquid-permeable, thermoplastic material. The fastening of the liquid-permeable material to the outer surface of the absorbent material of the tampon (10), which consists of a nonwoven ribbon section rolled up on itself and pressed radially to give the final form of the tampon (10), guarantees that the high absorbency of the nonwoven fibre material, based on capillary action, continues through the liquid-permeable, thermoplastic material onto its outside. In addition, the liquid-permeable material offers protection against fibres becoming detached and makes it easier to introduce the tampon into and remove it from the body cavity.

Abstract: A tampon pack, in particular for female hygiene, as indicated, which consists of a tampon applicator (1) having an applicator shell (2) and a plunger (3) telescopically mounted therein to be axially movable, and of a tampon (4) which is located in the applicator shell (2), has a withdrawal cord (5) and can be pushed out of the applicator shell (2) by means of the plunger (3), a flexible packaging film (6) being provided in the region of the introduction end (7) of the tampon (4) and being held on the applicator shell (2). The special point of the tampon pack is that the packaging film (6) surrounds substantially the entire surface of the tampon (4), is made to be substantially impermeable to water vapor and is provided, on the inside facing the tampon (4), with a coating having a high coefficient of sliding friction.

Abstract: An apparatus for compressing a blank into a compressed tampon is provided. In the direction of its central axis, the apparatus comprises in succession a push rod, a transmitting device, a tampon press and an ejector mandrel. The carrier jaws of the transmitting device are concentrically movable with respect to the axis and have a closed passage channel whose cross-section is suitable for the blank or the pressed tampon. The cross-section of the push rod is notably smaller than the passage opening provided in the open portion of the carrier jaws for the tampon blank. The carrier jaws have in the direction of the axis, a width corresponding to at least the length of the blank. The tampon press has pressing jaws which are radially movable with respect to the axis between a receiving position of the tampon blank and a pressed position. The ejector mandrel serves to eject the tampon out of the tampon press back into the transmitting device and against the push rod.

Abstract: An apparatus is provided for attaching a withdrawal tape to a catamenial tampon. The apparatus is designed so that the withdrawal cord is frictionally wound up upon a centering mandrel in a controlled manner and then pressed against the withdrawal end of a tampon to provide a spiral of withdrawal cord in the same uniform shape and quality while manufacturing such tampons at high speed. The withdrawal cord is picked up by a driver and wound up in an annular chamber between a centering mandrel and the driver. The driver comprises two cylindrical driver shelves arranged concentrically to one another at a radial distance and each having a driver tooth. The cooperation between the driver teeth and the two driver shelves makes it possible to perfectly guide the withdrawal cord during the course of winding the same.

Abstract: Between a pre-shaping device and a pressing device for tampons there is interposed a delivery device. The longer parallel legs of the L-shaped pressing jaws are set at a distance which corresponds to the diameter of the tampon. The shorter legs of the pressing jaws are oriented towards the longer leg of the other pressing jaw. The width of the pressing jaws corresponds at least to the length of the tampon and of the withdrawal cord. The delivery device is arranged for reciprocating movement transversely of the pressing jaws and has a transmitting channel which corresponds to the opened pressing device as well as a receiving channel which corresponds to the closed pressing device. Also interposed along with the delivery device, and in alignment with the transmitting channel, there is a transmitting device, and there is also a transmitting device in alignment with the receiving channel and the ejecting channel.

Abstract: A blister package, particularly for sanitary tampons (3) for women hygiene, is comprised of a pressed foil (1) forming a deep hollow and of a cover foil, and comprises a deposit (6) for an additive, preferably a lubricant. The deposit (6) is arranged in a main trough (19) intended to receive the sanitary tampon (3). The deposit (6) may be shaped as a cup (5) of the pressed foil (1) and opened in the hollow of the pressed foil (1) or be covered or separated from the main trough (19). The deposit (6) may be relieved through the opening of the blister package and brought in contact with the end (3a) and the pad (3), but the deposit may also be pressed by means of the finger applied pressure in the direction of the end (3a) of the pad (3) to coat it before the opening of the blister package and the use of the pad (3). The additive will therefore be applied immediately before using the sanitary tampon, so that all of the amount of additive available achieve its purpose.
