PURPOSE: To standardize a connector as a disposable part by connecting a connector positioned in the front side of a storage cylinder of a double delivery cartridge to a discharge port of the storage cylinder through a permanent, axial push-fit coupling. CONSTITUTION: Two storage cylinders 2 are formed integrally with each other by injection molding of a synthetic resin and are separable each other in a double wall configuration. A discharge port 4 at each cylinder end face 3 is formed by a round hole and a central axis line 13 of this hole has an equal distance C from an inner wall 12 of the both cylinders. Two substantially tubular sleeves 27 are formed in a connection section 21 of a connector 20 formed as an injection molding of a synthetic resin and fitted to two connecting tubes 5. Accordingly, even when a volume mixing ratio is not 1:1, an opening 4 and a longitudinal part 25 connected thereto can be formed equally, so that all cartridges in series can be operated by the same delivery apparatus. |
