摘要:
A substance for preparation of a beverage contained in a sealed flexible sachet is extracted with a device which provides a chamber formed by two members configured so that they each form a cavity which is substantially one-half of the chamber and so that when brought and fastened together, they form the chamber containing the sachet and provide for penetrating the sachet for subsequent injection of water for extraction of the substance. One member has a base which has a surface from which raised portions project and holes for flow of extract therethrough, and this member and the sachet are configured so that upon placing the sachet on the member, one sachet sheet is supported by the raised portions and a sealed peripheral sachet edge extends onto a rim of the member. Upon bringing and fastening the two members together, the members grip the sachet edge for fluid-tight sealing and shape the sachet uniformly and confine the substance within the sachet within the cavities, and the sachet is penetrated. After sealing, water is injected into the sachet under pressure to force the sachet sheet in contact with the raised portions against the portions so that this sheet first is deformed at multiple locations by the raised portions before being torn so that the substance is wetted and then, the sheet is deformed further and torn at multiple locations by the raised portions for flow of extract from the sachet to and through the base holes.

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.

An apparatus for extracting a substance contained in a sachet for preparation of a beverage has a first member having raised and hollow portions for forming a flow zone and a second member for cooperating with the first member to form a chamber to contain the sachet for extraction of the substance and to grip the edge of the sachet to ensure fluid-tightness upon being tightened, each member being configured for forming substantially half of the chamber for containing and ensuring a specific sachet shape. In one embodiment, the second member has provision for perforating an upper surface of a sachet for introducing water into the sachet. In another embodiment, the first member has an injector member which projects beyond the raised portions for perforating and introducing water into the sachet. The first and second members may be mounted on a chassis so that the members are mounted about an axis so that upon movement about the axis, the members are brought together so that they form the chamber, and a rim of the first member and an edge of the second member cooperate for gripping an edge of a sachet.

Fluid comestibles are prepared from substances, particularly roast and ground coffee, contained in cartridges by supporting a peripheral portion of a first surface of a sealed cartridge with a holder which has a base which includes a grille and relief surface element so that the remainder portion of the first surface is positioned adjacent the relief surface element. An opposing cartridge surface is pierced for injection of water into the cartridge while maintaining the base in the position adjacent the first surface, and while maintaining the base in a fixed position, water is injected under a pressure of greater than atmospheric pressure into the cartridge to deform the first surface remainder portion against the relief surface element first to press the first surface against the relief surface element and to wet and compact the substance and then to tear and open the remainder portion of the first surface for flow of fluid comestible from the cartridge and through the grille in a plurality of streams.
摘要:
A powdered substance, which is suitable for preparation of a beverage with an extraction fluid, is extracted for preparation of a beverage. The substance which is compacted in a form of a cake, is contained within a sachet between two sachet sheets which, prior to extraction of the substance, protect the substance against oxygen and water vapor and which extend to sealed edges for containing the substance within the sheets prior to and during extraction. In effecting extraction, one sheet is perforated to provide at least one opening for injection of extraction fluid, and extraction fluid is injected under pressure into the sachet for contacting and deforming the compacted substance cake and for extracting the substance in the sachet, and the other sheet is deformed against a surface having portions forming, upon deformation of the second sheet, local breakages in that sheet for opening that sheet for flow of extracted beverage substance. The cake and sheets advantageously are configured so that there is free space between at least one of the cake surfaces and one sheet for allowing the substance to expand between the sheets, and a cake surface may have a concave shape or may have channel impressions therein and be positioned adjacent the at least one opening for injection of extraction fluid.

Devices for use in a water injection coffee extraction machine are in a form of a hollowed ring which may be fixed about the base of the extraction head of the coffee machine, and a grill or other member, which allows passage of extraction water therethrough, is positioned transversely within the interior of the ring so that upon fitting the ring about the extraction head base, the grill or other member is positioned adjacent the base of the extraction head. The grill may have projections which extend in a direction away from the extraction head, and the member may have a centrally disposed portion which has a form of a needle which also contains at least one hole.

摘要:
Devices for being fitted to a beverage making machine extraction head have a ring member which has a wall which extends to define a hollowed interior portion suitable for being fitted about a periphery of a coffee machine water injection system extraction head which surrounds a water injection passage. The hollowed interior is defined further by a base connected to and disposed transversely with respect to the wall. The base may be a ring wall portion which provides a grill and which has projections extending therefrom, or may be a ring wall portion which has a hole therethrough and which has projections extending therefrom, or may be a ring wall portion which has a centrally disposed needle portion which contains at least one opening so that upon the ring member being fitted about the extraction head, the base is positioned adjacent a base of the extraction head, and so that the projections or needle are positioned to extend away from the extraction head base. The devices also include a cartridge holder, which may be an element integral with the ring member or separate therefrom, and a cartridge holder support.

The invention pertains to the field of the beverage preparation machines having an ingredient processing module for preparing a beverage with at least one ingredient supplied with a capsule. The machine comprises a positioner arranged to hold at least one capsule out of the ingredient processing module. It further comprises a sensing arrangement adapted to detect an event related to the insertion by a user of a capsule and/or the presence of the capsule on or into the positioner. The machine is configured, upon detection of the event, to transfer the capsule to the ingredient processing module by using transfer means, and then to start the preparation of the beverage. More particularly, the invention relates to a machine providing a convenient and safe solution to fully automate the preparation of a beverage.
