Sealed cartridge for making a beverage
First Claim
1. A cartridge for preparing a fluid food product, comprising:
- a container comprising a cover configured for rupturing against protruding hollowed-out elements of an extraction cage upon injection of a fluid into the cartridge at at least a rupturing pressure within the cartridge;
a food component contained within the container and configured for producing the food product upon contact with the fluid; and
a barrier mounted to the container adjacent to the food component and being substantially impervious to the food component for retaining the food component within the container;
wherein the container and barrier are configured for puncturing by an injection needle for injecting the fluid into the container to produce the rupturing pressure, the barrier being configured for resealing itself against leakage of the food component from within the container upon withdrawal of the needle therefrom.

Abstract
The invention relates to a sealed cartridge, provided to be extracted under pressure, containing a substance (15) for preparing a beverage, comprising a dish (9) with a bottom (10) and a side wall (11), having substantially the shape of a frustum of a cone, and a circular edge with a diameter greater than the bottom, and a cover (12) welded to the periphery of the edge of the dish, in which the cover (12) consists of a flexible material which is impermeable to oxygen, chosen from the group consisting of aluminum, an aluminum/plastic composite, an aluminum/plastic/paper composite, pure or multi-layer plastic, the said cartridge not comprising a filter or a weakening zone and the cover being intended to be torn only through the effect of the force of the extraction fluid when extraction starts, the said cartridge comprising, in the dish at the level of the bottom, a barrier (13) that is automatically resealable against leakage of the substance upon withdrawal of the fluid injection needle.

12. A cartridge for preparing a food product, comprising:
-
a container comprising a cover configured for rupturing against protruding hollowed-out elements of an extraction cage upon injection of a fluid into the cartridge at at least a rupturing pressure within the cartridge;
a food component contained within the container and configured for producing the food product upon contact with the fluid; and
a barrier mounted to the container adjacent to the food component and being substantially impervious to the food component for retaining the food component within the container;
wherein the container and barrier are configured for puncturing by an injection needle for injecting the fluid into the container to produce the rupturing pressure, wherein the barrier is sufficiently resilient for perforating with the needle and resiliently resealing itself against leakage of the food component.
