Abstract
The present disclosure is directed towards a needleless injection device that includes a body, a gas generator, an injection system that extends axially along an injection axis and includes at least one plunger, an active ingredient reservoir, an injection nozzle that delimits at least one injection channel, a cover that houses the body of the device, a removable cap that protects a lower downstream end of the injection nozzle, a stopper that houses the cap, and a blocking element. The stopper is pivotally mounted about the injection axis between a closed position in which the stopper is locked on the injection device and an open position in which the stopper is unlocked from the injection device. The blocking element is radially interposed between the cap and the stopper, and is configured to block, by friction, the relative pivoting of the cap and of the stopper, about the injection axis.
