Patent ID: 8365961

Claim:
A device for delivering a substance, the device comprising a stationary portion and a movable portion that is movable relative to the stationary portion between a rest position and an activated position, the device further comprising abutments for putting the movable portion into abutment relative to the stationary portion, wherein the abutments need to be forced past in order to enable the movable portion to go from the rest position to the activated position, the abutments comprising a first abutment carried by the movable portion and a second abutment carried by the stationary portion, at least one of the first and second abutments being mounted on a resilient portion of the stationary portion and/or of the movable portion, the resilient portion being deformable between an abutment configuration and a retraction configuration and having a reinforcing part that bears against a zone of the resilient portion, wherein the reinforcing part reinforces the resilient portion and increases resistance of the resilient portion during deformation between the abutment configuration and the retraction configuration.
