Abstract
A container (1) for dispensing a pressurised product and a method for manufacturing the container. The container (1) includes a body (2), a collar (3) and a dispensing valve (4). The body (2) is moulded from PET or like plastics, and has a shaped neck (7) surrounding an opening. The collar (3) is also moulded of plastics material, and is shaped to be snap-fitted to the shaped neck (7) of the body (2). Alternatively, the collar (3) is shaped to straddle the internal and external walls of the neck (7) of the body (2) to form a shaped lip therearound. The dispensing valve (4) is attached to the neck/collar (7,3), and has an outer flange (11) which is formed of malleable material and is shaped to fit about and be retained by the collar (3).

A container for dispensing a pressurised product, comprising:
- a blow-moulded body of integrally formed PET plastics material including a base and shaped neck defining an opening having external and internal walls;
- a collar having:
- a groove which straddles the external and internal walls of said opening and which forms a shaped lip therearound,
- a skirt snap fitted to said body and depending from an external portion of said shaped lip, and
- an arm depending from an internal portion of said shaped lip and guiding said collar into position about said opening;
- and
- a dispensing valve attached to said collar, said dispensing valve including an outer flange of malleable material which straddles around and compresses said lip and which pushes against said arm to thereby pinch said collar to said container, said flange sealingly engaging said body, collar, and valve together.
