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