<p>An injection container of the dual-chamber cartridge type is formed from two separate coaxial tubular containers, comprising a front container for a first product and a second container for a second product. The front container is closed at its rear end by a fluid-sealing wall, and the rear container is arranged in this wall, and is itself closed at its front end by a fluid-sealing movable wall. In this movable wall are arranged connections, which may be opened by the displacement of said wall, to allow the second product to be transferred into the front container, to be mixed with the first product. Preferably the first product is solid and may be dissolved or dispersed by the second product, which is liquid. Also preferably, the fluid-sealing wall closing the rear end of the front container is also movable, and may be urged forwards to expel the mixture formed in the front container from said container to injection.</p> |
