Abstract
A home carbonation system includes a mechanical lock to lock a bottle within the carbonation system during carbonation. The system also includes a gradual releaser to controllably release pressure after the carbonation and to delay the unlocking of the bottle from the mechanical lock after the carbonation has ended.
Claims4
A home carbonation system, the home carbonation system comprising:
- a carbonating arm connected to a housing of said home carbonation system such that lowering the arm causes carbonation, said carbonating arm having a cam surface;
- a normally open valve having a plunger pressable by said cam surface during carbonation to seal said normally open valve;
- a mechanical lock that is configured to lock a bottle in an upright position within said home carbonation system when the carbonating arm is lowered from a non-carbonation state;
- and
- a gradual releaser comprising a damper and active after said carbonation has ended, the gradual releaser configured to cause the carbonating arm to be raised, opening said normally open valve, at a rate that is sufficiently gradual such that the carbonating arm is raised to the non-carbonation state to unlock said mechanical lock only after all pressure is released from said bottle.
