Dropper comprising a container and a head actionable in several directions

Abstract

The present invention concerns a dropper comprising a container and a head, the container extending between an open proximal end and a distal end along a longitudinal axis. The container delimiting a product storage inner volume. The head is tightly mounted at the proximal end to tightly close the proximal end. The head comprises an actuator and a deformable bulb mounted between the actuator and the proximal end. The deformable bulb defines an inner chamber with a variable volume. The actuator is mobile with regards to the container along an inclined direction, between a rest configuration, and a dispensing configuration in which the actuator deforms the bulb to decrease the volume of the inner chamber. The inclined direction comprises a non-null component along the longitudinal axis and a non-null component along a transverse axis perpendicular to the longitudinal axis.
