Ejector (1) for liquid or paste product, consists of a moulded body (2), part of which contains a product to be ejected through an outlet, made with a through bore (23) containing a sliding thrust cylinder (3). The cylinder has toothed section (10) and is actuated by a lever (4) with a pivoted pawl (16) and a non-return pawl (18). One end (22) of the cylinder is shaped to engage with the non-return pawl to prevent it being inserted the wrong way round; its teeth go right round its surface and are formed by two straight surfaces (11, 13) joined by a curve (12). |
