Valve for discharge fluids kept under pressure in a container

A valve assembly (14) for discharging fluids (15) from a container (10) having a long axis and under pressure, said valve assembly including a valve body (16) fixed to a container lid (13), said lid having a circumferential edge (28) and a discharge tube connected to said valve body (16) and further connected to an ascending pipe (21) configured to extend into the container for fluid communication and discharge from the container, and an atomizer cap (23) having an integral body and having an atomizer nozzle (22) secured within said cap (23) and configured for connection to the discharge tube (18) and oriented approximately perpendicular to the long axis of the container, a discharge opening in said cap (23) aligned with said nozzle (22) for discharging of fluid from said container, said cap (23) having an inner integral circumferential surface, configured to fit over said lid, the improvement in a catch mechanism connecting said cap (23) to said circumferential edge (28) of the container lid (13), comprising at least one offset portion on said circumferential edge (28) of the container lid (13), a complementary offset portion on said inner circumferential surface of said atomizer cap (23), said cap being attached to said circumferential edge of said container lid with said offset portion of said cap engaging said offset portion of the circumferential edge of said lid and thereby connecting the cap to the container lid and establishing a rotationally stable fixation of said cap (23) to the container lid (13) to hold said atomizer nozzle (22) in predetermined orientation with respect to said container (10).
