Obtaining fluid comestibles from substances contained in cartridges
First Claim
1. A process for preparation of fluid comestible products comprising:
- placing a sealed cartridge, which comprises opposing surfaces and a body portion disposed between the surfaces and which contains roast and ground coffee particles, within a holder means which comprises (i) a base which comprises a grille and relief surface element members and (ii) a rim which circumscribes the base and which is positioned and configured so that the rim supports a peripheral surface portion of a first of the two cartridge opposing surfaces so that the cartridge is supported within the holder means and so that a remainder portion of the first surface, which extends from the peripheral surface portion, is positioned at a position adjacent the relief surface element members and so that upon subsequent introduction of water under a pressure greater than atmospheric pressure, the first surface remainder portion deforms initially and contacts the relief surface element members and subsequently is torn at a plurality of locations by the relief surface element members;
placing the holder means supporting the cartridge in a fixed position and piercing the cartridge surface which opposes the first surface to provide for introducing water under pressure into the cartridge; and
maintaining the holder means in the fixed position and injecting water within the cartridge via the pierced cartridge surface under a pressure of greater than atmospheric pressure sufficient so that, initially, the first surface remainder portion is deformed and pressed against the relief surface element members and the coffee particles are wetted and compacted and so that, subsequently, portions of the first surface remainder portion which are pressed against the relief surface element members reach their breaking stress so that the portions are torn to open the remainder portion so that coffee extract made by contact of water and coffee particles flows from the cartridge and through the flow grille in a plurality of streams.

Abstract
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.
