  • the first and second crown 115c, 116c thus comprise each one a plurality of column-like elements which detect recesses of depth lower than the height of the respective crown; this means that the recesses thus detected do not extend until the bottom of the crown, but leave a portion of the latter completely full, and this portion is precisely the one which acts as a barrier.

  • the column-like elements of the crowns lie on the same radial line, i.e. the straight line which starts off orthogonally with respect to the tangent to the circumference detected by the respective crown.
  • the Applicant has found that in particular with beverages such as tea or coffee, the presence of a double crown 115c, 116c of column-like elements in combination with flow-guiding walls 111, 112, 113 oriented on a radial straight line connecting them with at least one column of crowns 115c, 116c, allows a further and optimal mixing of the beverage, together with a reduction of the local transit speed and local pressure increase that allows the beverage to be mixed with the fluid and to acquire the maximum of the aroma without losing creaminess when such creaminess becomes a particular characteristic. This applies especially to coffee.
  • the substantially rectilinear path of the flow of the beverage along the direction detected by the axis X is therefore prevented because of the head portion 114t of the interdiction means 114.
  • the capsule for distributing beverages 100 object of the present invention there is a drop-splitting element 119 within the cavity of the outlet opening 106, which is designed in such a way as to avoid a whirling flow inside it, in particular at least locally in rotation with respect to the longitudinal axis X of the capsule, which can bring spurts out of the glass or cup or anyway out of the container within which said beverage is delivered after it has exited from the capsule 100.
  • the drop-splitting element comprises a plurality of side openings, which in the attached figures are shown in a number equal to eight.
  • the outlet opening 106 of the beverage is closed by a removable laminar peelable element, adapted to complement the barrier properties of the capsule, already described above for the rest of the product 100.
  • said removable laminar peelable element 191 can be realized in the same way as the retaining sheet 121, in particular by means of a sandwich of plastic materials as previously described.
  • said removable laminar peelable element it allows to repair the duct adjacent to the outlet opening 106 from dust and microbes, keeping the capsule as most hygienic as possible and never letting the flow of the beverage enter in contact with external plastic parts.
  • Figure 6 shows an alternative form of embodiment for the flow distributor element 110, which has similar characteristics with respect to the latter; for this reason, except for the differentiation parts, the reader is referred to the previous portion of the description.
  • the means of deviation and distribution of liquid have a single series of walls 111 b joining the annular border of the fluid conveying element with the outer crown of column-like elements 115.
  • the single series of walls 111 b may also be absent, and this case is the one represented in Figure 8 , wherein the flow distribution and deviation means comprise the column-like elements and the funnel created is devoid of reinforcing elements.
  • the walls 111 b extend along a plane which comprises the longitudinal axis X and a secondary axis which extends radially from the center of the capsule towards the perimeter of the capsule.
  • the single series of walls 111 b consists of 4 walls, which are more preferably mutually orthogonal between them, which divide the funnel formed by the bottom wall 103 into four circular sectors. These 4 walls are supporting ribs for the lid lying above.
  • Figure 7 shows a further form of embodiment for the capsule object of the invention, which is characterized in that the fluid conveying element 110 has an annular border 141 provided with perforator elements 190, preferably but non exclusively triangular, which can be arranged evenly spaced along the circumference detected by the annular border 141 itself. These elements are designed to assist the perforation of the lid for the delivery of the beverage.
