Patent number: 12035684Abstract: There is disclosed herein a frothing assembly (21) to froth milk in a container (11). The assembly (21) includes: a body (25); a motor (33) fixed to the body and having an output shaft (34) that is rotatably driven about a longitudinal axis (35) of the shaft (34); a frothing device (36) rotatably driven by the shaft (34) and to be submerged in the milk in the container (11); and a perforated member (43) at least partly surrounding the frothing device (36) and spaced from the frothing device (36) by a clearance (44), wherein rotation of the frothing device (36) causes movement of milk in the clearance (44) and movement of milk through the perforated member (43) to be circulated back through the container (11) and the clearance (44) to cause frothing of the milk.Type: GrantFiled: May 8, 2023Date of Patent: July 16, 2024Assignee: Breville Pty LimitedInventors: Duncan Bruce Hellmers, Giovanni Baez, Norman Oliveria, Gerard White

Patent number: 11980319Abstract: A coffee puck removal device (10) to remove a coffee puck (24) from a portafilter (20) is disclosed herein. The coffee puck removal device (10) has an open compartment (22) containing the coffee puck (24), the coffee puck (24) having an exposed major outer face (26) and a major inner face (28) when the coffee puck (24) is located in the open compartment (22). The device (10) includes: a body (12) having a rim (14) surrounding an aperture (16), with the rim (14) being configured to engage the portafilter (20), with the open compartment (22) facing the body (12) to inhibit air passing between the portafilter (20) and the rim (14); and a vacuum source (30) to remove air from the aperture (16) so that air pressure applied to the major inner face (28) is greater than air pressure applied to the exposed major outer face (26) so that the coffee puck (24) is removed from the portafilter (20).Type: GrantFiled: June 27, 2019Date of Patent: May 14, 2024Assignee: BREVILLE PTY LIMITEDInventors: Duncan Bruce Hellmers, Stephen John Mcclean, Pierce Barnard, Caroline Valentina Vasta, Andrew Robert Morgan, Andrew Domenic Gregorace, Robert Grassia
