A tampon applicator is disclosed which has a semi-spherically shaped insertion tip for facilitating insertion of a catamenial tampon into a woman's vagina. The tampon applicator includes a first member capable of housing an absorbent tampon. The first member has a central longitudinal axis and first and second ends. An insertion tip is integrally formed on the first end of the first member and extends outwardly therefrom. The insertion tip contains an aperture which extends therethrough and has a side wall which is aligned essentially parallel to the central longitudinal axis. The insertion tip contains a plurality of pleats arranged to form a semi-spherical configuration. The pleats are capable of expanding radially outwardly as the tampon is expelled from the first member. The applicator further includes a second member telescopically mounted in the second end of the first member. The second member is adapted to expel the tampon through the insertion tip as it is pushed into the first member. The tampon applicator is also disclosed in combination with a catamenial tampon. An apparatus and method are also disclosed for crimping, pleating and forming a tip on a hollow tube.

La présente invention concerne un applicateur de tampon présentant un bout d'introduction hémisphérique facilitant l'introduction d'un tampon cataménial dans le vagin d'une femme. L'applicateur de tampon comporte un premier élément pouvant contenir un tampon absorbant. Ce premier élément est caractérisé par un axe central longitudinal, par une première et une seconde extrémités. Le bout d'introduction, formé d'une seule pièce sur la première extrémité du premier élément, est orienté vers l'extérieur. Le bout d'introduction contient une ouverture transversante présentant une paroi latérale sensiblement parallèle à l'axe central longitudinal. Le bout d'introduction comporte une pluralité de plis disposés de façon à former une hémisphère. Ces plis peuvent se déployer radialement vers l'extérieur lorsque le tampon sort du premier élément. L'applicateur comporte en outre un second élément télescopique monté dans la seconde extrémité du premier élément. Le second élément est conçu pour faire sortir le tampon par le bout d'introduction à mesure qu'il est poussé dans le premier élément. L'invention concerne également un applicateur de tampon adapté à un tampon cataménial. L'invention concerne enfin un procédé et un dispositif de sertissage, de plissage et de formage d'un bout sur un tube creux.
