Embodiment Construction

[0100] Figures 1 to 4 show a first example of a capsule according to the principles of the invention. The capsule 1 comprises a body 2 in the form of a cup and an injection wall 3 closing the open part of the cup. The body can be made, for example, of thermoformed plastic. The body comprises an upper edge 20 against which the injection wall 3 rests and is welded and / or bonded thereto. The injection wall 3 is advantageously a pierceable and liquid- and gas-tight plastic or aluminum septum or a composite multilayer.

[0101] The body 2 comprises a chamber 4 in which the food substance to be extracted is contained. The food substance occupies a position in the chamber in the form of a bed of substance whose surface transverse to the fluid passage through the bed is defined on the one hand by the opening means 5 and on the other hand by the weakening of the injection fluid. And means 6 for distributing the fluid across the chamber 4 are defined. The chamber is also delimited b...

Abstract

The invention relates to a capsule for delivering a drink by injecting a pressurized fluid comprising a body (2), an injection wall (3), a chamber (4) containing a bed of food substance to be extracted, means for retaining the internal pressure (5) in the said chamber. The improvement consists in the provision of an injection space (7) allowing a means of injecting fluid in the form of at least one jet of fluid to be introduced through the injection wall and in providing a means (6) for breaking the jet of fluid and distributing the distribution of fluid at a reduced speed across the surface of the bed of substance. These means may adopt various forms such as that of a rigid or flexible perforated wall, or a layer of discrete elements or a spongy layer. Such a capsule improves the flow of liquid extract through the pressure retaining means (5) and improves the extraction conditions.

Description

technical field [0001] The present invention relates to a capsule for preparing and dispensing a beverage in which the beverage is extracted and / or dissolved from a food substance contained in the capsule by injecting a pressurized fluid into the capsule. Background technique [0002] Many examples of capsules are known which contain a food substance to be extracted under the pressure of a fluid, usually water, in order to form a beverage. An example of a capsule is described in patent EP 0512468 . The capsule is designed to be inserted into an extraction machine. The closed end of the capsule comprises a tearable septum which opens under the action of fluid pressure upon contact with a septum support equipped with relief for tearing the septum and ducts allowing the passage of liquid extracts . [0003] Another example of a capsule is described in application WO 03 / 059778 A2. The capsule comprises a closed chamber containing the substance to be extracted or dissolved, a...
