Supply cartridge, system of supply cartridges and process of operation of a machine using said system of supply cartridges

Supply cartridge (1) adapted for supplying a support (2) of single portions, that presents a plurality of single dose portions (21) adapted so as to contain an edible substance, such as for example roast and ground coffee, to a machine (10) for preparing edible products, such as for example aromatic beverages, a comprising:

• a package casing (11) provided in a general parallelepiped-like form, or similar, presenting a width (W), a depth (D) and a height (H), and
• a support (2) of single portions provided in a strip-like form, or similar, and comprising a plurality of single dose portions (21) that present a length (C) and a width (L) and are disposed successively in adjacent manner along a support extension (E),
• whereby said support (2) of single portions is provided inside of said package casing (11) with a downstream edge (22) in the proximity of a package corner (12),
• whereby the region of said package corner (12) presents at least one weakening line (13) of said package casing (11) adapted so that can be manually ruptured and thereby provided an exit opening of said support (2) of single portions out of said package casing (11), characterized
• in that said weakening line (13) is provided with a semicircular or semi-trapezoidal configuration, for example in a U-like form, or similar, upwards oriented, so that provides a pivoting-like connection of the respective package corner (12) upon said exit opening, thereby exerting a weight upon said support (2) of single portions with a force component opposite to the traction force exerted upon said support (2) of single portions as the latter is pulled out of said package casing (11).
