Abstract
A device for dispensing liquids, in particular drugs, comprises a reservoir (11) provided with a neck (30) of reduced cross-section being engaged by a stopper element (16). The reservoir is completely covered by a cap (25) which has at one end a movable push button (28) which abuts against the bottom portion of the reservoir (10). In order to transfer the device from its storage position to its activated position, the operator must press on the push button (28) in such a way that the stopper element (16) penetrates into the interior of the reservoir beyond the neck of reduced crosssection (30). This device can be used as an injection syringe, a spray dispenser, or an applicator for the skin or eyes.
