Patent number: 11903515Abstract: A drinks machine has an output nozzle for delivering hot water or steam, Steam is used by a milk frothing unit whereas hot water is delivered by the output nozzle directly to the exterior of the drinks machine for collection in a drinks vessel. A single nozzle is thus provided for steam or hot water delivery and there is no need for any accessory when delivering hot water. This means that there is reduced cost, fewer components to lose, and simplified cleaning, in that only per-use cleaning of the milk frothing unit is required, not the fixed parts of the appliance associated with the milk frothing unit.Type: GrantFiled: December 21, 2018Date of Patent: February 20, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bart-Jan Zwart, Peter Aljosja Kot, Ede Szabo, Oliver Fecko, Tim Gerard Tibbe, Mérijn Stam, Vittorio Perazzolo

Patent number: 9750664Abstract: To provide an infant drinking device with a more reliable aerator, the infant drinking device comprises a teat, a reservoir for holding a liquid, a connector for detachably connecting the reservoir to the teat, and an aerator. The aerator (e.g., a duckbill valve) includes a deformable opening (e.g., a slit) whereby internal/external pressure differential during use of the device is reduced in an open position of the opening by allowing air to enter through the opening into the reservoir and such that leakage of fluid from an inside of the drinking device to an outside of the drinking device is hindered in a closed position of the opening. During assembly of the teat, connector and reservoir, a minimally defined deformation of the opening of the aerator is enforced by at least one of a geometrical property and a material property of the teat or the connector.Type: GrantFiled: March 14, 2013Date of Patent: September 5, 2017Assignee: KONINKLIJE PHILIPS N.V.Inventors: Jason Palmer, Bart-Jan Zwart, Christopher John Huff
