Double cartridges for two-component compounds manufactured in one piece by injection molding have separate reservoir cylinders. Discharge channels starting from each cylinder space are separated in a common orifice by two wall sections which start from separate cylinder walls and are brought in duplicate up to the channel end; in addition, the channels receive a separate closure inserted axially from the outside. The one-piece connection at the orifice occurs either by an end-face web between the wall sections or through circumferential sections of an orifice ring embracing the channels. As a result, the diffusion paths in the plastic material of the cartridge are extremely long. Yet the advantages of the one-piece double cartridge with respect to manufacture and handling are preserved. A variant with longitudinally bored closure remaining in the orifice is described, which forms together with a rotatable slide element a seal intended for opening and closing.

A double discharge cartridge molded in one piece for two-component compounds, said cartridge comprising two reservoir cylinders arranged with parallel axes die by side, said cartridges having an orifice with an end face which is common to both cylinders and which connects them in one piece, said orifice containing two axial discharge channels, each discharge channel starting from a respective cylinder, the two discharge channels being separated by two wall sections, said wall sections extending continuously from separated cylinder walls, said extending wall sections being separated up to the end face, forming a diffusion barrier between said channels.
