CA 2269619

Novel tampon and methods for their production is provided herein. One form of such tampon configures an absorbent tampon comprising: a) an absorbent; b) a liquid-permeable cover at least partially surrounding said absorbent, said absorbent and said cover forming a softwind having a first end and a second end, said softwind being folded upon itself at three spaced-apart locations to form an M- shaped profile, said folded softwind having first, second and third portions consecutively and integrally joined together, said second portion containing a cleft; c) withdrawal means for removing said tampon from a body cavity, said withdrawal means being attached to said second portion cleft; d) a cylindrically-shaped pledget formed by compressing said folded softwind, said pledget having an insertion end and a trailing end, with said insertion end located adjacent to said second portion, said pledget being capable of being comfortably removed from a body cavity by pulling on said withdrawal means which causes said insertion end to collapse upon itself; and e) means for securing said first end and said second end together.

On décrit un tampon et son procédé de fabrication. Le procédé consiste à couper un élément absorbant séparé dans une longueur d'absorbant. Chaque élément absorbant est ensuite façonné pour former un absorbant allongé comportant un pourtour externe. Une enveloppe perméable aux liquides est fixée sur le pourtour externe de l'absorbant allongé pour former un enroulement souple. Ce dernier comporte des première et deuxième extrémités et est replié sur lui-même de sorte que les première et deuxième extrémités sont alignées adjacentes l'une à l'autre. L'enroulement souple comprend deux plis intercalés qui le divisent en une première, une deuxième et une troisième partie. Un cordon de retrait est fixé à la deuxième partie de l'enroulement, lequel est ensuite comprimé en un tampon de forme cylindrique. Le tampon comprimé comprend une extrémité d'introduction et une extrémité arrière, l'extrémité d'introduction étant située juste à côté de la deuxième partie. Le tampon comprimé et le cordon de retrait associé constituent un tampon dont l'extrémité d'introduction peut se replier sur elle-même lorsqu'une pression s'exerce sur le cordon de retrait pour assurer un retrait sans gêne à partir de la cavité corporelle.
