Abstract
Abstract A dispensing cartridge having a retaining flange connected to an end thereof, the retaining flange including at least two flat portions disposed in parallel planes, and a plurality of webs connecting the flat portions. The retaining flange is designed as a box construction with outwardly open hollow spaces having constant or increasing rectangular cross-sections in a direction perpendicular to the dispensing flow direction. The webs connecting the flat portions may be in two sets, with the webs in one set extending perpendicular to the webs in the other set. The retaining flange may be manufactured by injection molding. The box construction design of the flange requires only slightly more material than a single retaining flange, yet provides a gain in stability that allows simpler and more economical adapters of the dispensing appliances to be used.
