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.
