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.

Tampon, especially for feminine hygiene, and a process and apparatus for producing this

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 longitudinal ribs (,) are separated one from another by outwardly open longitudinal grooves (,). A process for preparing the tampon and an apparatus useful in the process are also disclosed.

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 When the inner sleeve is withdrawn out of the outer sleeve, the tampon is held in place by the retention element and transferred into the outer sleeve.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. The transfer of the tampon out of the inner sleeve into the outer sleeve is thereby ensured when the tampon applicator is utilized, and at the same time a simple, economic mass production of the tampon regulator is ensured.

Tampon applicator

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.

Feminine hygiene tampon and method and apparatus for making same

Tampon pack

Apparatus for transmitting a tampon blank to a tampon press

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.

Apparatus for attaching a withdrawal cord to a tampon

Apparatus for pressing workpieces of absorbent material, particularly

Tampon blister pack

A tampon pack is provided for containing a tampon of the type having a coated insertion end and an uncoated rear end. In accordance with the invention, a constriction is provided in that portion of the pack adapted to contain the rear end of the tampon and by virtue of this constriction, the insertion end of the tampon is held out of substantial contact with the container walls.

Tampon pack especially for a coated tampon containing medicaments

A catamenial tampon is provided in the form of absorbent material enveloped by a liquid permeable cover which is then folded and compressed into a cylindrical shape. The enveloped absorbent material is in the form of a flat cushion and is first folded into front, central and rear sections with the front and rear sections overlying the central section. A withdrawal cord is looped around the first folded cushion which is then folded around the withdrawal cord and compressed into the final tampon shape. The resulting tampon expands when wet into a cup-shaped configuration.

Method of making tampon with a non-woven wrap

A combination tampon and packaging therefor is provided for which a lubrication may be applied to the tampon only immediately before use. The combination provides a separating sleeve slideably surrounding the periphery of the forward portion of the tampon and being spaced away from the forward portion of the tampon. A lubricant is deposited on that portion of the sleeve spaced away from the forward end of the tampon and a wrapper is provided enclosing both tampon and the sleeve. On removing the wrapper, the tampon may be slid forward relative to the sleeve and the lubricant automatically transferred to the tampon immediately prior to use.
