Problems solved by technology

The drawback of this improvement is that after a large number of capsules are used, the fixed seal wears out, so that the quality of the resulting drink deteriorates due to the passage of water through a seal that is no longer fully effective

Embodiment Construction

[0066] now refer to figure 2 The first embodiment will be described in detail.

[0067] It should be noted that the invention will be described below with reference to a particular design of a capsule, ie a capsule comprising a cup-shaped base and a closure foil member. However, it will be appreciated that other designs of the capsule are possible, for example a capsule in the form of a lenticular lens in which two substantially matching and opposing walls (eg foils) are sealed at eg an annular edge. A capsule according to the invention generally comprises at least two opposing wall parts (surfaces) connected to each other at their respective edges to form a sealed flange-like rim region enclosing a sealed interior.

[0068] This embodiment shows a capsule holder 13 with a relief element 12 designed to tear and pierce the foil part 5 closing the cup-shaped base 4 of the capsule 1 . It may eg be that the foil member 5 is torn as soon as the pressure inside the capsule exceed...

Abstract

The invention proposes a method for producing a beverage from an ingredient-containing capsule. The method comprising the following steps: inserting a sealed capsule into a capsule enclosure space of a beverage production device; enclosing the capsule by a relative displacement of at least two enclosing members which define the capsule enclosure space; opening an inlet face of the capsule and injecting a fluid under pressure into the capsule in order to open an outlet face of the capsule, the opening being assisted by the fluid pressure inside the capsule, wherein the capsule is provided at its outer surface with sealing material which is exposed to the fluid pressure in the capsule enclosure space; and after enclosing the capsule, having the fluid pressure reigning in the capsule enclosure space at least partially act on the sealing material, such that in turn the sealing material is pressed against one of the enclosing members thus constituting a flow resistance, the flow resistance being sufficient to guarantee a pressure build-up inside the capsule sufficient for the pressure-assisted opening of the outlet face of the capsule.

Description

technical field [0001] The present invention generally relates to capsules containing beverage ingredients, beverage production systems comprising such capsules and methods for producing beverages based on ingredients contained in such capsules. Background technique [0002] Within the scope of this description and the appended claims, the term "beverage" also includes edible liquids. [0003] The background of the invention is the field of capsules containing beverage ingredients or other edible ingredients such as soups. By interacting these ingredients with a liquid, beverages or other foods, such as soups, can be produced. The interaction may be a process such as extraction, brewing, dissolution, mixing, etc. Such a capsule is for example adapted to contain ground coffee for the production of a coffee beverage by entering hot water under pressure into the capsule and expelling the coffee beverage from the capsule. [0004] A system and method for obtaining edible liqu...
