Abstract
A tampon, particularly for feminine hygiene, includes an absorbent body and a variably perforated or apertured cover. The absorbent body has an introduction end, a withdrawal end, and a longitudinal main portion therebetween. The cover includes a fluid-impervious plastic material in the form of a resilient three-dimensional web having a multiplicity of perforations. The perforations are varied over the length of the tampon so that a differentiated expansion of the tampon while absorbing fluid is achievable. Preferably, the degree of perforations of the cover increases towards the withdrawal end of the tampon at least over a portion of its length.
