摘要:
The invention relates to a filter holder comprising a filter housing having a bottom and a dispensing duct or aperture through said bottom. A valve with a valve stopper is arranged for selectively opening and closing the dispensing duct or aperture, the valve stopper being supported by a pivoting arm and resiliently biased towards a closed position. The valve stopper is closed when the filter holder is attached to a hot-water dispensing unit of a beverage producing machine, so that hot pressurized water will soak a beverage ingredient, for instance coffee powder, loaded in the filter cup. The valve is calibrated so that it will open once a certain pressure in the filter cup has been achieved. Once opened, the valve stopper will remain open irrespective of the pressure inside the filter cup, by means of the arrangement described here below. The filter holder further comprises a cam located between the bottom of the filter housing and the pivoting arm which supports the valve stopper. The cam has a cam profile co-acting with the pivoting arm. The cam is movable, preferably around a pivoting or hinge axis to selectively take different positions. More particularly, the cam has at least a first position wherein the cam profile prevents closing movement of the valve stopper and a second position wherein the cam profile allows closing movement of the valve stopper. The cam is resiliently biased towards the first position by a suitable resilient member, for example a spring, such as a torsion spring. Furthermore, the filter holder comprises a slider which co-acts with the cam to move the cam from the first position towards the second position against the resilient action applied on the cam. The slider is advantageously resiliently biased in an inactive position and is forced to move towards an active position by direct or indirect co-action with an element of a water dispensing unit whereto the filter holder is attached. The slider is con figured and arranged so that during said movement from the inactive position to the active position, the slide pushes the cam towards the second position, i.e. the cam position which allows closing of the valve stopper. The resilient force applied on the slider is overcome by the co-action of the slider with the above mentioned stationary element. Once the co-action with the stationary element ceases, the slider is resiliently returned to the inactive position.

A brewing apparatus including a housing having a movable lid; a water heater connected to the housing; a pod carrier removably connected to the housing; a seal connected to the lid for movement towards and away from a top side of the pod carrier as the lid is moved between an open position and a closed position; and a hot water discharge head connected to the lid for delivering hot water from the water heater in a direction towards the top side of the pod carrier when the lid is in its closed position. When the lid is in its closed position, the movable lid closes over the top side of the pod carrier and, the seal is adapted to be located against a perimeter side of the pod carrier for sealing along the perimeter side.

A filter-holder includes a cylindrical cup (1), a filtering chamber (4) defined by the inner side wall (5) of the cup and a perforated base (6) provided with a grille (7), a vessel (9) collecting the infusion placed underneath the grille (7) and provided with elements for evacuating the infusion (11), and at least two infusion, outlet pipes (15, 16). The filter-holder includes an infusion dispensing trough (10) placed beneath the vessel (9) which includes elements channelling (13, 35) the infusion flow towards the filter-holder outlet pipes. A selecting member (S1, S2) generates a relative rotational motion between the vessel (9) and the trough (10) to obtain an infusion flow either through one outlet pipes only (15), or through both outlet pipes (15, 16).

A ladle holder (20) comprises either a releasable spray packing member for ground coffee or a spray recess for pre-packaged coffee blocks, and a filter ladle (10) may be provided as required with either a ground coffee filter or a filter adaptor (70) for coffee blocks. In the latter case, the filter ladle (10) fits into a holder with an upper ejector pin (83) for ejecting used coffee blocks. The holder is hinged to one bearing pin (30) and, when fully inserted, engages an abutment under the other bearing pin (40) by means of a tab. The two bearing pins (30, 40) engage helical projections (11, 12) on the filter ladle (10) to form a bayonet-like attachment and position the filter ladle (10) in engagement with a ladle seal.
摘要:
A substance for preparation of a beverage contained in a sealed flexible sachet is extracted with a device which has two members which are configured to each form a cavity which is substantially one-half of a chamber so that upon being tightened together for holding the sachet for extraction of the substance, the sachet is provided with a desired shape and is perforated to enable injection of water for extraction of the substance. Upon perforation, water is injected which deforms a surface against raised portions of one of the members and then tears the sachet to allow flow of beverage from the sachet through holes of the member containing the raised portions.

The brewing device is composed of a housing part including a piston, vertically slidable in the housing part. On the housing part, a filter basket holder is mounted which is pivoted horizontally about the tilting axis and is provided with a filter basket to be filled with ground coffee. When the piston is lowered and reaches into the filter basket (i.e., its working position), the filter basket forms with it a pressure chamber, in which the ground coffee is enclosed, into which, on the piston side, hot water under pressure is urged through a conduit, and from which, on the filter basket holder side, the prepared espresso coffee beverage is discharged through at least one outlet opening. When the piston is lifted, the filter basket holder with the filter basket can be swung about a vertically extending tilting axis out of the range of effect of the piston. The tilting range of the filter basket holder reaches from its working position to its feed position, in which the filter basket is accessible from the outside. Only in its working position is the filter basket holder secured in respect of the housing part against movement in a vertical direction by supporting elements provided on both the filter basket holder and the housing part.
