The present invention provides a nozzle (10) for a pressurized container comprising a discharging tube (11), an actuator (12) and blocking means (20). The discharging tube (11) is coupled to a valve of a pressurized container when the nozzle (10) is applied on a pressurized container. The valve in its open position allows the discharge of a product contained in the pressurized container through the discharging tube (11) when the actuator (12) is pressed. The blocking means (20) prevent the opening of the valve when the discharging tube (12) is an undesired inclination. The blocking means (20) comprises a movable, non-compressible barrier (21) and a recess (22). The recess (22) is such that the recess (22) contains at least partially the barrier (21). The recess (22) further has a 360~ access symmetry for the barrier (21) so that the access of the barrier (21) into the recess (22) is obtained at a desired inclination of the discharging tube (11) independently of the orientation of the nozzle (10) when the nozzle is handled by a user. The blocking means (20) prevent any substantial movement of the actuator (12) when the actuator (12) is pressed, and consequently the opening of the valve when the nozzle (10) is applied on a pressurized container, when the barrier (21) is located at least partially outside the recess (22).

Cette buse (10) pour récipient sous pression comporte un tube d'évacuation (11), un actionneur (12) et un organe de blocage (20). Le tube d'évacuation (11) est relié au clapet du récipient sous pression lorsque la buse (10) est appliquée sur ledit récipient. En position d'ouverture, le clapet autorise la sortie du produit contenu par le récipient et ce, par le biais du tube d'évacuation (11) lorsque l'on appuie sur l'actionneur (12). L'organe de blocage (20) empêche l'ouverture du clapet lorsque le tube d'évacuation (12) est incliné de façon incongrue. Cet organe de blocage (20) comporte une barrière (21) mobile, non compressible et une alvéole (22) structurée de manière à loger, au moins partiellement, la barrière (21). Cette alvéole a une symétrie d'accès de 360· relativement à la barrière de sorte que la venue de la barrière (21) dans l'alvéole (22) se fait à une inclinaison souhaitée du tube et ce, indépendamment de l'orientation de la buse (10) lorsque celle-ci est manipulée par un utilisateur. Cet organe de blocage (20) empêche tout mouvement de grande ampleur de l'actionneur (12) lorsque l'on appuie dessus et, partant, empêche l'ouverture du clapet lorsque la buse (10) est appliquée sur le récipient sous pression quand la barrière (21) se trouve, au moins partiellement, sortie de l'alvéole (22).
