Abstract
Systems for preparing comestibles, particularly beverages, from substances contained in sealed cartridges have a water injector, a support for a cartridge holder and a cartridge holder which includes a flow grille and relief surface element so that upon introducing water under pressure into the cartridge to prepare a beverage, a face of the cartridge adjacent the relief surface element and flow grille is deformed and then torn to enable a fluid comestible to be removed from the cartridge and pass through the relief surface element and grille.
Claims27
A device for use with apparatus for preparing fluid comestible extracts comprising a holding means having a peripheral rim portion for encompassing an area about a face of a sealed cartridge containing a substance for preparation of a fluid comestible and a rim surface configured for supporting the cartridge and suitable for forming a fluid-tight seal with the cartridge and having a flow grille which extends in a plane from the rim portion across the area encompassed by the rim portion and having a relief surface element which comprises a plurality of spaced-apart members which are positioned adjacent the flow grille in the area encompassed by the rim portion and configured to project in a direction away from the flow grille for, upon extraction, piercing a cartridge face and upon piercing a cartridge face, allowing fluid comestible from the pierced cartridge to flow about the projecting members to and through the flow grille orifices.
In an apparatus for extracting a substance contained in a cartridge for the preparation of a beverage having a water injector means, a means for holding a cartridge, a cartridge holder support means for supporting the holding means, and fixing means for fixing the support means and holding means so that upon extraction, a face of a cartridge positioned in the holder means is pierced by the injector means and the cartridge is maintained in the holder means, the improvements comprising:
- a holding means having a peripheral rim portion for encompassing an area about a face of a cartridge containing a substance for preparation of a fluid comestible and a rim surface configured for supporting the cartridge and suitable for forming a fluid-tight seal with the cartridge and having a flow grille which extends in a plane from the rim portion across the area encompassed by the rim portion and having a relief surface element which comprises a plurality of spacedapart members which are positioned adjacent the flow grille and in the area encompassed by the rim portion and configured to project in a direction away from the flow grille for, upon extraction, piercing a cartridge face and upon piercing a cartridge face, allowing fluid comestible from the pierced cartridge to flow about the projecting members to and through the flow grill orifices.
