Abstract

A cartridge for preparing a flavoured drink comprises an infusion chamber for containing flavouring materials and infusing a liquid with flavouring substances. A passage in the chamber wall allows liquid exchange between the infusion chamber and its exterior. A flow drive system drives a liquid flow between the infusion chamber and its exterior through the passage in a flow direction which projects from the chamber wall. The cartridge may have an outer wall which is movable to cover and close the passage. A manual control may be used to open or close the passage. The manual control may have a cover covering a top-side of the chamber wall and interlocking with the chamber wall. The cover may include a cup-shaped grip partitioned in first and second upwards open parts, for admitting respective finger(s) of the user. A partitioning wall may separate the parts and allow exertion of a rotational force.

Abstract

A cartridge for preparing a flavoured drink comprises an infusion chamber (2) for containing flavouring materials and infusing a liquid with flavouring substances. A passage (31) in the chamber wall allows to exchange liquid between the infusion chamber and the exterior of the chamber. A flow drive system drives in the infusion chamber a liquid flow between the infusion chamber and the exterior of the chamber through the passage, which has a flow direction which projects from the chamber wall. The cartridge can further have an outer wall (40) covering a part of the outer surface chamber wall and movable to cover and close the passage, such that upon moving the outer wall, the outer surface is pressed onto the outer wall to seal off the passage. A manual control can be used to exert a manual force by the user to open or close the opening. The manual control has a cover (6) covering a top-side of the chamber wall and interlocking with the chamber wall. The cover comprises a cup-shaped grip (60) partitioned in a first upwards open part and a second upwards open part, for admitting respective finger(s) of the user. A partitioning wall (62) separates the parts and allows to exert with the fingers a rotational force. The partitioning wall extends radially from a peripheral edge of the grip inwards. By squeezing with fingers on the partitioning wall, the edge can be deformed to release the interlocking.

Abstract

A cartridge (1) for controlled brewing of loose-leaf tea in a cup, comprising an infusion chamber (2) for containing loose tea leaves (3) and infusing a liquid with substances from the tea leaves to brew tea. A chamber wall (20) impervious to the liquid defines the infusion chamber. In the chamber wall is a passage (21) between the infusion chamber and an exterior (5) thereof. The passage has an open state in which the infusion chamber is in liquid communication with the exterior, to transport the substances from the infusion chamber into liquid in the exterior during brewing tea. In a close state the infusion chamber inside is closed off from liquid in the exterior to stop a concentration of the substances in the liquid in the exterior from increasing. A manual control manually controllable by a human-being allows to bring the passage from the open state into the closed state.
