A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage. A gas cylinder can include a cap with a flange and catch below the flange. The catch can be engaged by a cylinder support to move the cylinder into contact with a piercing element to pierce the gas outlet of the cylinder and form a seal between the cylinder and gas receiver. A pressure indicator can have a single pressure sensor to indicate a capacity of a gas cylinder to deliver pressurized gas and a pressure in a beverage container.

The invention relates to an ultrasonic infusion device comprising an ultrasonic wave generator, a basin physically connected to the ultrasonic wave generator to form a rigid assembly and wherein said basin is arranged to comprise an ultrasound-conducting liquid, and an infusion container comprising a base, wherein vibration absorbing means are mounted between the rigid assembly and a container carrier, and wherein the base of the infusion container is dimensioned to be supported by the container carrier and is shaped to ensure continuous contact with the ultrasound-conducting liquid.

An integrated infuser/mixer pump system features a liquid inlet configured to receive a liquid drawn from a liquid source, a gas inlet configured to receive an inlet gas from a gas source, a pump and motor combination configured to received the liquid and provide pumped liquid, a gas/liquid mixture chamber configured to receive the pumped liquid and the inlet gas, and mix the liquid and the inlet gas into a gas-infused mixture, and a gas-infused mixture outlet configured to provide the gas-infused mixture; the gas inlet having a gas liquid mixing valve with a mixing orifice that has a mixing orifice size dimensioned to provide the inlet gas to the gas/liquid mixture chamber with an inlet gas volumetric flow rate in order to mix the pumped liquid and the inlet gas with a predetermined mixture ratio that depends on the mixing orifice size.
