Embodiment Construction

[0055] figure 1 One half-shell 1 is clearly shown, a second half-shell (not shown) is welded along a weld line 2 to close the container 4 . The container has a cavity 3 containing the substance to be extracted, for example roast and ground coffee powder. A rod 5 is located between the two symmetrical half-shells. The rod as figure 2 As shown, its upper part has a plurality of holes 6 through which hot water reaches to prepare coffee. The lower part of the rod also includes a tip 7 for piercing the weld seam of the two half-shells. The tip portion also includes a plurality of openings 8 which allow the free passage of coffee but prevent the passage of coffee grounds. When the container is introduced into the extraction system, the rod is pushed down so that the tip 7 pierces the weld seam of the two half-shells.

Abstract

The present invention relates to a closed capsule designed to be extracted under pressure in an extraction device, containing a substance 43 for the preparation of a beverage, comprising a closed system 44, 45 containing the said substance and a means 46, 48 inside the said system allowing the said capsule to be opened at the time of its use and allowing the said beverage to flow out without contact with its extraction system.

Description

technical field [0001] The present invention relates to a container / capsule for extraction under pressure containing substances for the preparation of food products such as beverages. Background technique [0002] Cartridges for extraction under pressure and containing substances for preparing beverages are already available on the market. The patent EP0512468 of applicant company just relates to such a kind of cartridge case. The cartridge can be inserted into an extraction system. Thus, under the effect of the pressure of the fluid entering the cartridge, the cartridge opens on the support part of the system containing the raised elements. The problem with the cartridge is that the beverage extracted from the cartridge overflows the support member and flows through the piping system, which means that it is difficult, if not impossible, to The system can be used to extract substances other than roast and ground coffee, since beverage residues will remain on said support ...
