Abstract

A dispensing device comprises a hollow syringe body (100) and a plunger (200). A lateral inlet port (120) is provided for transferring a flowable product into a reservoir inside the syringe body. A check valve (600) in the port permits transfer of the product into the reservoir while preventing the product from leaking from the reservoir. The plunger has a portion configured as a toothed rack (211). An advancement mechanism (140) for the plunger comprises a spring element (141) having an outwardly bent arcuate shape, which engages the toothed rack. Deformation of the spring element into a flattened configuration causes the spring element to advance the plunger in the distal direction. An actuator element (144) converts axial pressure into lateral pressure onto the spring element to advance the plunger.
