Abstract
A closure device for the neck of a pressurized container comprises a dispensing nozzle provided with a skirt adapted to be secured to the neck of the container. A closing member within the nozzle comprises an actuating rod extending lengthwise towards the tip of the nozzle and an obturator having an annular wall normally sealingly engageable with a cylindrical internal wall portion of the nozzle. The cylindrical wall portion is connected to the portion of the nozzle containing the actuating rod by an elastically deformable portion whereby the nozzle can be tilted to tilt said rod and release the seal between the obturator and the cylindrical internal wall portion of the nozzle.
Claims16
A dispensing closure device for mounting on the neck of a container containing a pressurized liquid product to be dispensed, said device comprising:
- (a) a dispensing cap of an elastically deformable material comprising a dispensing nozzle portion having an axial channel therethrough, and a skirt portion comprising means for securing the cap onto the neck of a container,
- (b) a closure member mounted within the dispensing cap and comprising an actuating rod housed inside the axial channel in the nozzle, and an obturator connected to said rod and operable by tilting of the nozzle portion relative to said skirt,
- (c) said obturator comprising an annular side wall,
- (d) said cap comprising a wall portion surrounding and normally sealing engaging said annular side wall of the obturator, and
- (e) an elastically deformable peripheral wall zone connecting the said skirt and nozzle portion of the cap whereby upon deformation of the said deformable wall zone in response to the nozzle portion of the cap containing the rod being tilted relative to the part of the cap which contains the obturator, the seal between the obturator and the said side wall is broken.
