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.
