Claim:
1. A disposable package having a reservoir filled with a portion of an ingredient to be combined with a base liquid for the preparation of a liquid product, said package having an injection moulded monolithic plastic body with a bottom having an outer periphery and a circumferential wall joining said bottom at said outer periphery thereof, an upper edge of said circumferential wall bounding an aperture which is hermetically sealed by a top sealing film fixed on a circumference thereof to said upper edge, the plastic body furthermore having a central column which is at its lower end integral with a centre of the bottom, said column projecting upwards from said bottom to an upper end of said column, wherein said reservoir of the package surrounds said column and is bounded by said bottom, said circumferential wall, and said top sealing film, wherein said ingredient is in direct contact with said bottom without interposition of a filtering web, wherein a channel extends in said column from an inlet at said upper end of the column to a blind end, wherein the top sealing film above said inlet is pierceable by a base liquid feed lance allowing said feed lance to dispense base liquid into said channel, wherein said column at said upper end thereof, is provided with indentations between raised protruding bosses, wherein said indentations are in. communication with said channel in said column and with said reservoir, so as to allow said base liquid that is dispensed from said feed lance to flow to and through the indentations and then into the reservoir to be combined with the ingredient therein, wherein the bottom is embodied as a closed bottom with a multitude of filter holes, so that said liquid introduced via said indentations into said reservoir interacts with the ingredient and the liquid product thus obtained flows out of said reservoir through said filter holes in said bottom, wherein said bottom has an annular flexible portion around said column such that said column is movable downwards relative to said circumferential wall of said plastic body from an initial position to a lower operative position through engagement with said feed lance and relative displacement of said feed lance and said package, wherein said multitude of filter holes is provided in said annular flexible portion of said bottom, wherein said multitude of filter holes have been formed as said plastic body is injection moulded, wherein said bottom has a rigid annular region around said annular flexible portion, and wherein said package is provided with a bottom sealing film fixed at a circumference thereof to said rigid annular portion of said plastic body and extending underneath said flexible portion of said bottom, which said bottom sealing film is adapted to break upon relative motion of said column and of said flexible portion of said bottom relative to said circumferential wall from said initial position to said lower operative position, said breakage creating one or more outflow openings in said bottom sealing film allowing for outflow of said liquid product from the package.
