ABSTRACT:
A package (10) for dispensing a fluid (26) in the package under gas pressure has a biaxially oriented polyethelene terepthalate bottle (12) with a neck (14). A dispensing head (22) is attached to the neck (14). A normally closed valve (16) is mounted in the neck and has a housing (50) sealed to the inside surface of the neck (14). The housing (50) has a syphon flange (54). An integral structure (56) having a spring (58) at one end and a poppet (60) at a second end rests on the syphon flange (54). The housing has an opening (48) above the syphon flange 54). The integral structure (56) extends between the syphon flange (54) and the opening (48). The integral structure (56) is dimensioned so that the spring (58) is compressed to bias the poppet end of the integral structure (56) into sealing engagment around the opening (48). The dispensing head (22) has an integral diaphragm (42) and rods (52) and (46) extending above and below the diaphragm (42). Lever (24) applies downward force on the rods (52) and (46) to move the poppet end of the integral structure (56) out of sealing engagement around opening (48) to create a flow path (92) for the fluid (26) in the package (10) through the valve housing (50), the opening (48) and spout (28) of the head (22). A resilient grommet (148) forms a second seal around the opening between the housing and the poppet end of the integral structure.
