Title:
互いに同心的に配置された2つの室を備えたカートリッジのための押出装置
Document Type and Number:
Japanese Patent JP2004532123
Kind Code:
A
Abstract:
The invention relates to a discharge device for a cartridge (1) having two chambers (2, 3) that are arranged concentrically to one another and are closed by pistons (9, 10), the discharge device having a discharge ram (11) having a thread (12), which is axially displaceable by being screwed into an end piece which is arranged at the rear end of the cartridge (1) and has an internal thread (14). In order to allow simple manufacture of the discharge device and to facilitate its handling, the discharge ram (11) has an inner plunger (16) which exerts pressure on the piston (9) of the inner chamber (2) and, arranged concentrically with the inner plunger (16), an outer plunger (17) which exerts pressure on the ring-shaped piston (10) of the outer chamber (3), the outer surface of the outer plunger (17) being provided with the thread (12) which extends over its entire length. Furthermore, the end piece having the internal thread (14) is in the form of a threaded ring (13). As a result of this configuration of the discharge ram (11), it can be produced in the form of a one-piece component from plastics in an injection-moulding process.
