Abstract

L'invention concerne un contenant (2) à utiliser avec un instrument à main (6), en particulier à usage dentaire, et destiné à distribuer une pâte d'obturation dont la viscosité peut être réduite par apport d'énergie vibratoire, le contenant (2) étant conçu pour contenir la pâte d'obturation et comportant, à son extrémité avant, un orifice de sortie (8) pour la distribution de la pâte d'obturation. L'orifice de sortie (8) est ménagé à travers une canule (4), par exemple en acier. Il est possible d'influer de manière positive sur la viscosité de la pâte d'obturation à travers ladite canule (4). En particulier, le degré de fluidification de la pâte d'obturation peut ainsi être augmenté de manière significative.
