Heating and dispensing fluids

摘要

A heat transfer cap assembly for use with a dispensing canister containing a pressurized product, such as shaving gel. The cap assembly defines a volume for retaining hot tap water to heat gel in a thermal conductor forming a conduit between a nozzle adaptor and an outlet in the side of the cap assembly. When the nozzle is released, the conduit moves out of alignment with the outlet so as to block any "drool' of the gel remaining in the conduit during later expansion. The outer cap is rotatable to a lock position to disallow activation of the nozzle and to further block the outlet.
