LONG-LASTING CARTRIDGE PIERCER |
摘要 |
A device (1) for extracting an ingredient in a cartridge (9) by supplying an extraction liquid such as heated water into such cartridge, comprises: upstream and downstream cartridge enclosing parts (7,8) relatively movable between an open position for inserting and/or removing such cartridge and a closed position for forming an extraction chamber (11) enclosing such cartridge during extraction; and at least one piercer selected from an upstream piercer (34) borne by the upstream part (7) for opening an upstream portion of such cartridge and a downstream piercer (30) borne by the downstream part (8) for opening a downstream portion of such cartridge. The at least one piercer (30,34) has a generally tapered shape, in particular a tapered shape that has a truncation surface (35) delimiting a piercing edge (34′). At least one tapered piercer (34) has a base with a reinforcing foot extending transversally away from the tapered shape, in particular a foot having a body (34″) extending around an entire periphery of the base and/or a body (34′″) extending radially or diameterally or diagonally from the base. |
