DESCRIPTION:
BRIEF SUMMARY
The invention is concerned with a method for preparing a liquid product and also with a device for carrying out such a method. More specifically, the invention is aimed at a method for preparing a liquid product, in which a liquid and/or steam are introduced under pressure into a cartridge containing a certain amount of at least one substance capable of forming said product by the effect of said liquid and/or steam and this product is collected outside the cartridge, as well as at a device comprising an apparatus and a cartridge for preparing a liquid product by the introduction under pressure, of a liquid and/or of steam into a cartridge containing a certain amount of at least one substance capable of forming said product by the effect of said liquid and/or of steam, this apparatus comprising means for supplying liquid and/or steam to the cartridge, as well as means for collecting the liquid product outside the cartridge. The invention is aimed more particularly at a cartridge containing a certain amount of at least one substance for the preparation of a liquid product by the effect of a liquid and/or of steam introduced under pressure into the cartridge, this cartridge comprising a watertight casing including a side wall and further two walls, one of which provides the bottom of the cartridge and the other closes the opposite end of the cartridge.
The invention relates in particular to a cartridge such as indicated above, this cartridge being intended for use in preparing a hot or a cold drink, such as coffee or chocolate, or a liquid food such as soup, by means of an apparatus of a conventional type such as a coffee machine, which comprises a device for injecting a liquid such as hot water or hot milk or again steam under pressure into a certain mass of a powdered substance, specially of ground coffee beans, in order to extract the soluble substances contained in the powdered substance.
Cartridges of this type are already known, which in particular offer the advantage that the original substance can be protected from ambient air or optionally kept under vacuum, in order to retain its freshness for a prolonged period of time.
The invention aims in particular at providing a cartridge of the above-described type, constructed so that it can be mass-produced at low cost, while ensuring a perfect conservation of the substance contained therein and optimal conditions for the preparation of the liquid product, specially with respect to the contact time of the powdered substance with the liquid supplied from the above-mentioned conventional type apparatus.
To this end, the cartridge according to the invention is characterized in that at least one part of the cartridge bottom is designed so that it can undergo a deformation of a predetermined magnitude without breaking, while moving away from the cartridge end opposite its bottom, under the effect of the introduction of said liquid and/or steam inside the cartridge.
The invention also relates to a collector member of liquid product for the above-mentioned cartridge. This collector member is characterized in that it comprises at least one inner space defined between an opening for the introduction of the cartridge and a wall having at least one aperture therethrough for the outflow of the liquid product, and in that it is provided with means for perforating the bottom of the cartridge when the latter has reached a certain degree of deformation from its original shape, thereby allowing the liquid product to flow out through said aperture.
Finally, the invention relates to a perforator and liquid injector member for the above-mentioned cartridge, this member forming an integral part of an apparatus or of a device for supplying a liquid, or being designed so that it can be fitted on the part of such an apparatus or device supplying the liquid, and this member being characterized in that it is provided with a wall formed to abut against the upper wall of the cartridge and with means for forming at least one aperture in the latter as said walls are applied one against
