- the supports 90 are arranged inside the collecting depression 330 between the labyrinth 30 and the edge 360.
- the base 33 also comprises, inside of the collecting depression 330, a plurality of supports 350, defined by further reliefs, arranged between the labyrinth 30 and the edge 360.
- the supports 350 substantially in the form of a circumferential arc, define a plurality of recesses 351 or compartments.
- a recess 351 is defined between a pair of adjacent supports 350.
- the recess 351 defines a preferential space for the deformation of the disc 5.
- the capsule 1 according to the present invention is provided with an anti-drip system which, exploiting the principle of capillarity, prevents the fluids remaining inside the cup 2 from leaking out.
- the base 33 comprises in effect the labyrinth 30.
- the labyrinth 30 comprises a plurality of labyrinth portions 320 which define a plurality of capillary channels 321.
- Each labyrinth portion 320 develops radially with respect to the base 33, between the collecting depression 330 and the conveying depression 340.
- Each capillary channel 321 connects the collecting depression 330 with the conveying depression 340 and defines an outflow path for the infused beverage towards the outlet opening 31.
- the capillary channel 321 is defined between two adjacent labyrinth portions 30 and is closed at the top by the disc 5, as shown in figures 2a and 2b.
- the capillary channel 321 is defined between an inlet 326 and an outlet 327.
