<p>A package (10) for dispensing a fluid (26) in the package under gas pressure has a biaxially oriented polyethelene terepthalate (PET) bottle (12) with a 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). An integral structure (56) having a spring (58) at one end and a poppet (60) at a second end rests on syphon flange (54). 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 engagement around opening (48). 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) from the package (10). A PET insert (218) makes a substantially line contact (232) with inside surface (230) of necked opening (214) of PET container (212).</p> |
