Attachment for a tea kettle

An attachment (2a; 2b) for a solvent container (3) for the time-controlled preparation of an extraction beverage comprises a base plate (500) for being mounted largely horizontally on the solvent container (3). The base plate (500) has an aperture (511) for an extraction product container (200) to pass through, and also a lifting apparatus which comprises a sleeve (400) on which the extraction product container (200) is held in such a way that it projects beyond the sleeve (400) at a lower end and can be filled with an extraction product through an upper opening in the sleeve (400). The lifting apparatus has a guide apparatus which is fixed to the base plate and on which the sleeve (400) is guided such that it can move in a direction largely perpendicular to the base plate in the sense of a linear guide (405, 515) between a lower and an upper position. In this case, the lower position defines a brewing position of the sleeve (400), in which position the extraction product container (200) is lowered, and the upper position defines an inoperative position in which the extraction product container (200) is raised in relation to the brewing position. The lifting apparatus also has a locking apparatus for locking the sleeve (400) in the brewing position. A timer (300) is also provided, said timer being designed for operating the locking apparatus in such a way that after a predefinable time period has elapsed, the sleeve (400) is unlocked when it is locked in the brewing position. The sleeve (400) is acted on by a restoring force along the linear guide (405, 515) in the brewing position, said restoring force restoring said sleeve from the brewing position to the inoperative position when the sleeve (400) is unlocked.
