Claims11
A device for preparing a drink from a cartridge, wherein the device comprises:
- a cartridge housing configured to hold a cartridge, the cartridge having a side wall and an upper face and containing a dose of a drink,
- a water inlet orifice, and
- a circular blade as a perforation element contained inside the cartridge housing, the circular blade being further connected to the water inlet orifice, wherein
- the circular blade is positioned so as to perforate only protrusions protruding from the upper face of the cartridge when the cartridge is placed in the cartridge housing, and wherein
- the device allows translation of the circular blade in a vertical direction in order to perforate the protrusions when the circular blade is lowered.
A device for preparing a drink comprising:
- a cartridge which comprises a hollow element designed to contain a dose, wherein said hollow element comprises a side wall, an upper face, and a lower face comprising an extraction membrane, wherein said cartridge further comprises several distinct protrusions protruding from said upper face, wherein each protrusion comprises at least one perforation zone having a sharp curvature thereby creating a zone of high pressure when a perforation element is applied to the at least one perforation zone,
- a cartridge housing configured to hold the cartridge,
- a water inlet orifice, and
- a circular blade as a perforation element contained inside the cartridge housing, the circular blade being further connected to the water inlet orifice, wherein
- the circular blade is positioned so as to perforate only the several distinct protrusions protruding from the upper face of the cartridge when the cartridge is placed in the cartridge housing, and wherein
- the device allows translation of the circular blade in a vertical direction in order to perforate the several distinct protrusions when the circular blade is lowered.
