Carbonation machine and a gas canister for a carbonation machine
A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.
1. A method of filling a gas canister with pressurized or liquified gas from a canister filling machine, the method comprising:
inserting a valve of a gas canister into an interior space of an adapter, through an opening of the adapter that is shaped to enable insertion of the valve, the adapter enabling a fluidic connection of the gas canister valve to a filling port of the filling machine, and comprising at least one channel that is configured, when the valve is inserted into the opening, to conduct pressurized or liquified gas from the filling port to the valve, the valve comprising: a canister port facing an interior of the gas canister and at least one exterior port that opens laterally to a longitudinal axis of the valve for facilitating inflow of the gas into and outflow of the gas out of the canister when the valve is in an open position, and to prevent the inflow or the outflow when the valve is in a closed position; and
filling the gas canister with the pressurized or liquified gas while maintaining the valve in the open position.
2. The method of claim 1 , further comprising maintaining said at least one exterior port stationary with respect to the gas canister, at all times when the valve is inserted in the adapter.
3. The method of claim 1 , further comprising connecting the adapter to a filling head of the canister filling machine.
4. The method of claim 1 , wherein the adapter is mounted on the canister filling machine.
5. The method of claim 1 further comprising operating a poppet that is slidable along the longitudinal axis and which, when in the open position, allows fluidic communication between the at least one exterior port and the canister port to enable inflow to the canister via said at least one exterior port or outflow from the canister via said at least one exterior port, and which, when in the closed position prevents fluid communication between the at least one exterior port and the canister port.
6. The method of claim 5 , comprising providing a resilient restoring structure configured to apply a restoring force to the poppet to maintain the poppet at the closed position.
7. The method of claim 6 , further comprising using a plunger with an exterior surface to provide an inward pushing force to overcome the restoring force and to slide the poppet from the closed position to the open position.
8. The method of claim 1 , wherein said at least one exterior port comprises a plurality of exterior ports.
9. An adapter comprising:
a body having an opening that is shaped to enable insertion of a valve of a gas canister that is configured to hold a pressurized or liquefied gas for carbonating a liquid, the valve comprising a canister port to a confined space within the gas canister, the valve also comprising at least one exterior port that opens laterally to the longitudinal axis of the valve; and
at least one channel that is configured to conduct pressurized gas from a filling port of a canister filling machine to one or more channels that are in fluidic communication with said at least one exterior port of a valve that is inserted into the opening,
wherein the adapter is configured to facilitate filling of the gas canister with the pressurized or liquified gas, while said at least one lateral exterior port is maintained stationary with respect to the gas canister at all times when the valve is inserted within the adapter.
10. The adapter of claim 9 , wherein the at least one channel comprises at least one laterally oriented channel that is configured to be in fluidic communication with the filling port when the adapter is attached to the filling machine.
11. The adapter of claim 9 , wherein the adapter comprises structure to enable attachment of the adapter to the valve, a distal end of the adapter configured to connect to a filling head of the filling machine.
12. The adapter of claim 11 , where the at least one channel comprises a longitudinally oriented channel at the distal end that is configured to be in fluidic communication with the filling port when the distal end is connected to the filling head.
