CA 2264768

A dispensing cartridge (10) is provided for viscous liquids, such as sealants. The cartridge (10) includes an elongated tubular cylindrical housing (12) defining an elongated interior chamber (16) having a cylindrical interior wall (14). A dispensing nozzle (18) is formed at one end (20) of the housing (12) and this dispensing nozzle (18) has an opening (22) open to the housing chamber (16) which is less in cross-sectional size than the cross-sectional size of the housing chamber (16). A substantially semi-spherical wall portion (26) extends between the cylindrical wall (14) of the housing (12) and the nozzle opening (22) while at least one reinforcing rib (28) extends outwardly from an outer surface of the semi-spherical wall portion (26). This reinforcing rib (28) not only reinforces the semi-spherical wall portion (26) of the housing (12) but also enables the cartridge (10) to be used in a standard caulking gun.

L'invention concerne une cartouche de distribution (10) destinée à des liquides visqueux tels que des produits d'étanchéité. La cartouche (10) comprend un logement cylindrique tubulaire allongé (12) définissant une chambre intérieure oblongue (16) présentant une paroi intérieure cylindrique (14). Une buse de distribution (18) est formée à une extrémité (20) du logement (12) et cette buse de distribution (18) présente un orifice (22) ouvrant sur la chambre (16) du logement, laquelle présente une taille de section inférieure à celle de la chambre (16) du logement. Une partie de paroi sensiblement semi-sphérique (26) s'étend entre la paroi cylindrique (14) du logement (12) et l'orifice (22) de la buse, tandis qu'au moins une nervure de renforcement (28) s'étend à l'extérieur d'une surface extérieure de ladite partie de paroi semi-sphérique (26). Cette nervure de renforcement (28) non seulement renforce la partie de paroi semi-sphérique (26) du logement (12) mais permet également d'utiliser la cartouche (10) dans un pistolet standard d'application de joint d'étanchéité.
