CAPSULE FOR PREPARATION AND SUPPLY OF BEVERAGE BY INJECTING THE LIQUID UNDER PRESSURE INTO CAPSULE Russian patent published in 2010 - IPC B65D85/804 

FIELD: food industry.

SUBSTANCE: capsule contains a hollow case, injection wall attached to the case and a chamber containing a layer of the substance subject to extraction. The capsule has a means of retarding the internal pressure in the chamber and a means of dispersing the liquid jet, reducing the liquid jet velocity injected into the capsule and distributing the liquid along the layer of the substance at a slow velocity. Space for injection is formed in the capsule between the wall and the chamber that enables to insert the means for injection of the liquid jet through the wall. The liquid jet dispersion means contains a wall separating the space for injection from the chamber containing a layer of the substance. The perforated wall is installed with a possibility of holding a layer of the substance in a compressed and unhydrated state. There is also a method of making the capsule.

EFFECT: improved flow of a liquid extract through a means of retarding the internal pressure as well as improved extraction conditions.
