  • Publication number: 20030077359
    Abstract: A sachet for preparation of a beverage. The sachet has a compact roast and ground coffee cake having first and second cake opposed surfaces extending between to a peripheral cake edge. The first opposed surface is substantially convex and configured for ensuring leaktightness in an extraction chamber that is configured for injecting water and extracting the coffee. The peripheral edge has a peripheral surface that is generally normal to the opposed surfaces. An outer sheet of a flexible material is impermeable to oxygen and water vapor and contains and impermeably seals the cake therein.

  • Patent number: 6068871
    Abstract: 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 compacted substance 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 first to provide at least one opening for injection of extraction fluid, and extraction fluid is injected under pressure into the sachet for contacting the substance and for extracting the substance in the sachet, and the other sheet advantageously 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.

  • Patent number: 5948455
    Abstract: A cartridge which contains a substance for preparation of a beverage and for use for preparation of the beverage. The cartridge has a base, a wall, a rim and a cover. The wall extends from the base to form a cup shape which is substantially a frustum shape, the rim extends from the wall and has a diameter greater than the base and the cover is welded to the rim to contain the substance in the cartridge. The base further has sheared areas thinned, with respect to a base remainder, which extend to define arrangements which are spiral, substantially sinusoidal portions, radial segments and concentric arcs of a circle and which, along a line of each sheared area to define thickness, have a thickness which varies along the line, the sheared areas providing, upon extraction of the substance in the cartridge under pressure, openings through the base for filtering and obtaining the beverage.

  • Patent number: 5826492
    Abstract: 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.

  • Patent number: 5762987
    Abstract: 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.

  • Patent number: 5649472
    Abstract: 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.
