Double delivery cartridge for two masses

A double discharge cartridge molded in one piece for two-component compounds, said cartridge comprising two reservoir cylinders arranged with parallel axes side by side, said cartridge having an orifice with an end face which is common to both cylinders and which connects them in one piece, said orifice contains two axial discharge channels, each discharge channel starting from a respective cylinder space, the two discharge channels being separated by two wall sections, said wall sections extending continuously from separated cylinder walls, said extending walls being separated up to the end face forming a diffusion barrier between said channels, said discharge channels being adapted to receive a closure inserted axially from outside the cartridge, closure having two projections each adapted to the respective crosssection of one said discharge channel and connected by a flange;

• said closure when inserted forming a seal to be removed prior to discharging the two-component compounds from the discharge channels;
• said projections extending into said discharge channels substantially past the end face to prevent diffusion of the component compounds particularly during long-term storage.
