There is a bush between the separator and the upper barrier fitted with the holes at the base allowing the liquid to flow out for the purpose of mixing the substance in the direction from the separator to the upper barrier. The bush may or may not be detachable from the separator. Inside the separator area determined by a ring fastened to the separator from below, there is mixing unit guide seated in a recess made in the mixing unit, whose arms have outflow holes at the ends placed in the walls of the recess, and connected to the central hole of the punch that punctures the barrier which has at least one notch in the centre of the casing, and is part of the casing where the punch, in its working position, after puncturing the lower barrier, seals the resulting hole with its outer surface during the outflow of the prepared mix, and the generating line of the punch is longer than half the length cut on the inside of the barrier, and the height of the punch is shorter than the height of the casing outflow duct. The method of beverage preparation from a substance contained in a hermetically sealed capsule in an appliance for preparing beverages, where the said capsule has inside its casing a separator separating the upper part of the capsule interior between that separator and the upper barrier of the casing, where the said substance is contained in the upper part and below the separator there is a mixing unit and an outflow duct sealed by the lower barrier, and the method comprises inserting the capsule in the appliance for preparing beverages and opening it from the base, and then puncturing the upper barrier and injecting liquid under pressure, according to the invention is characterised by that the liquid under pressure is injected by at least one pressure nozzle into the central hole of the bush which is typically free of the substance used for beverage preparation, and in the lower part of the side wall of the bush there is at least one opening located in the immediate vicinity of the capsule separator surface, through which the liquid under pressure is fed continuously from the base towards the upper part of the casing containing the said substance for the purpose of its preliminary dilution until at least one pressure control valve, through which the diluted substance flows into the mixing unit, opens and, when it is finally mixed, the substance is discharged from the capsule through the central hole in the mixing unit punch located in the outflow duct.

casing 1, made of a homogeneous material, as are all capsule components, which is sealed with theupper barrier 2 at the top and with thelower barrier 3 at the base, which act as tight closures of the separated capsule zones (Fig. 2 ). There is theseparator 4 inside thecasing 1 fitted with the rim 5 , which is connected tightly by welds to the ring-shaped surface 7 of the part of the casing 1 (Fig. 3 ). Theseparator 4 connected to thebush 35 and which may not be detached has at least one funnel-shaped passage 12 inside thearea 8 surrounded by thecentric ring 9 consisting ofsegments 10 with thegaps 11 between them, and theguide 13 placed in the geometric centre of thearea 8, which is inserted in the cruciform hole 14 - which can have other geometric shapes - of themixing unit 15, thus the rotation of themixing unit 15 inside thecasing 1 is prevented (Fig. 3 - 4 ,Fig. 12 ,Fig. 14 ). Thebush 35 has thecentral hole 28 for injecting liquid under pressure during capsule extraction, and the saidcentral hole 28 is generally free of the substances contained in theupper part 39 of the capsule, which means that the substance is not placed in the central hole but can enter it as a result of the migration from theupper part 39 of the capsule through theopenings 36 in thebush 35 walls, and the saidbush 35 supports theupper barrier 2, which is significant for the process of pasteurization of the content in the upper part 39 (Fig. 2 ,Fig. 3 ,Fig. 10 ). - The option of the
separator 4 connected to thebush 35, and which may be detached, is also fitted with thepassage openings 36 located near thesurface 37. The application of theopenings 36 improves the quality of mixing or diluting the concentrated liquids in the capsule (Fig. 3 ,Fig. 10 ). - In the area between the
separator 4 and themixing unit 15, there is at least onepressure control valve 43 in the form of thediaphragm 44 closing thehole 12, located in theseparator 4 above thediaphragm 44 placed in themixing unit 15. Thepressure control valve 43 opens when the pressure set in theupper part 39 of thecasing 1 for extracting, dissolving and diluting processes is exceeded (Fig. 3 - 4 ,Fig. 12 ). - The
cruciform hole 14 is made on the side ofsurface 16 fitted with a row ofspacing protrusions 17 and thering 29 comprising theprotrusions 18 and theindentations 19 between them and it hasarms 20 withoutflow holes 21 at the ends placed in thewalls 40 of thepunch 23base 46, while theconcentric rings 25 made ofshaped segments 26 andholes 27 are seated on the side of thebase 24 and connected to it and cannot be detached. (Fig. 12- 14 ). - The
outflow holes 21 are connected with thecentral hole 22 of thepunch 23 that punctures thebarrier 3 along at least onenotch 45, which on splitting into parts additionally seals theoutflow duct 41 in its upper part with the outer surface of thepunch 23base 46, thus forcing the outflow of the prepared mix through thecentral hole 22 and preventing the uncontrolled outflow of the prepared mix along theinner surface 42 of the outflow duct 41 (Fig. 3 ,Fig. 12 ,Fig. 15 ). The generating line a of thepunch 23 is longer than half the length d cut on the inside of thebarrier 3 , and the height h of the punch is shorter than the height H, of thecasing 1 outflow duct 41 (Fig. 2 - 3 ,Fig. 12 ,Fig. 15 ). - To empty the capsule of beverage ingredients it is placed in the
removable tray 31, which is then locked inside theappliance 32 for prepare hot or cold beverages and as thetray 31 is raised the capsule is additionally sealed around its entire perimeter and thus, therounding 33 moves towards thepunch 23 which punches through thebarrier 3 along at least onenotch 45, and on splitting into parts it additionally seals theoutflow duct 41 in its upper part with the outer surface of thepunch 23base 46, thus forcing the outflow of the prepared mix through thecentral hole 22 and preventing the uncontrolled outflow of the prepared mix along theinner surface 42 of the outflow duct 41 (Fig. 12 ,Fig. 15-17 ). At the same time, thebarrier 2 is also punched through by thenozzle 34 and after cold or hot water is fed under pressure into the capsule through thehole 38 the content in theupper part 39 of the capsule is dissolved/diluted and the prepared mixed content flows out through theholes 12,outflow holes 21, mixingunit labyrinth 15,central hole 22 and theoutflow duct 41 outside to a receiving vessel, namely a cup, a glass or another container (Fig. 12 ,Fig. 17 ,Fig. 18 - 19 ).

The method of beverage preparation from a substance contained in the hermetically-sealedcapsule 1 in theappliance 32 for preparing beverages consists in injecting water under pressure through at least onepressure nozzle 34 into theupper part 39 of thecasing 1 for the purpose of its preliminary dilution until thepressure control valve 43 through which the diluted substance flows into themixing unit 15 opens and, when the beverage is finally mixed it is discharged from thecapsule 1 through thecentral hole 22 in themixing unit 15punch 23 located in theoutflow duct 41 . (Fig. 3 ,Fig. 16 - 17 ).
