Definitions

  • the present invention regards a capsule for preparing beverages, for example coffee, tea, infusions or other.
  • These capsules usually comprise a container body, substantially shaped like a drinking-glass, which contains a dose of a food substance, for example powder coffee, suitable to produce the beverage by interaction with the hot water, for example through an infusion process, percolation and/or solubilisation.
  • a food substance for example powder coffee
  • the food substance is sealed inside the capsule by means of a sealing film, which is fixed on an annular flange which surrounds the entrance of the drinking-glass-like body.
  • the capsule is coupled to an extraction unit installed in the machine.
  • the extraction unit usually comprises a seat for receiving the capsule, an abutment body suitable to block the capsule in said reception seat, means for drilling the sealing film and/or the bottom of the drinking-glass-like body and means for dispensing hot water.
  • the reception seat is generally delimited by a substantially tubular-shaped jacket having an axial end facing and juxtaposed with respect to the abutment body.
  • the jacket and the abutment body are mutually moveable along the direction of the axis of the jacket, so as to allow the insertion of the capsule and its release after use.
  • the drinking-glass-like body When the capsule is in the reception seat, the drinking-glass-like body is coaxially inserted into the jacket with the annular flange which remains clamp-squeezed between the abutment body and the axial end of the jacket.
  • the annular flange In order to guarantee the airtightness of the reception seat, the annular flange often has sealing elements, for example one or more annular lips, which are pressed against the axial end of the jacket following the sealing of the abutment body.
  • An object of the present invention is to overcome the aforementioned drawbacks of the prior art through a solution that is simple, rational and inexpensive.
  • an embodiment of the present invention provides a capsule for preparing beverages by inserting the capsule into the reception seat of a machine suitable to dispense a process liquid, typically water (e.g. hot water), into the capsule, wherein said capsule comprises:
  • the function for centring the capsule in the reception seat is obtained by exploiting the lateral wall of the capsule and thus using only one centring rib.
  • the annular centring rib is interrupted by at least one radial opening suitable to place the annular interspace in communication with the external.
  • the annular centring rib does not provide any type of sealing for the reception seat, whose airtightness remains solely provided by the annular sealing lip.
  • the presence of at least one radial opening has the further advantage of slightly increasing the flexibility of the centring rib in the radial direction, thus facilitating the coupling thereof with the axial end of the jacket which delimits the reception seat.
  • the aforementioned radial opening can be defined by an empty space which extends axially from a vacant edge of the annular centring rib to the annular flange.
  • This aspect of the invention provides for a solution that is particularly simple for obtaining the radial opening.
  • the annular centring rib comprises only one radial opening, substantially taking a C-like shape.
  • the annular centring rib is sufficiently robust to guarantee an efficient centring of the capsule and to reduce the risk of being damaged during the manufacturing, the transportation and the use of the capsule.
  • the annular centring rib can have a substantially rectangular-shaped cross-section.
  • cross-section is generally used to indicate a section carried out with a section plane containing the axis of the centring rib, or the longitudinal axis of the lateral wall of the capsule.
  • This form of cross-section has the effect of conferring to the centring rib a high rigidity in the axial direction, increasing the robustness thereof as well as the capacity of an effective centring.
  • the annular sealing lip can have a vacant axial edge suitable to be compression-deformed by said axial end of the jacket of the reception seat.
  • annular sealing lip can have a tapered-shaped cross-section which narrows moving away from the annular flange.
  • the cross-section of the annular sealing lip can have a side which extends orthogonally with respect to the annular flange and which is faced towards the annular centring rib.
  • the annular sealing lip tends to be deformed always bending in the same direction, in particular towards the annular centring rib, thus improving the airtightness of the reception seat.
  • the lateral wall of the container body of the capsule can be tapered-shaped narrowing moving away from the annular flange, for example but not necessarily a substantially frusto-conical shaped.
  • the container body of the capsule can be made of plastic, for example but not exclusively made of polylactic acid (PLA). Thanks to this solution, the capsule is very economic and it can advantageously be obtained in large quantities.
  • PLA polylactic acid
  • the container body of the capsule can be obtained by means of thermoforming.
  • This embodiment has the advantage of allowing high production with relatively low costs.
  • annular centring rib and the annular sealing lip can be made of a single body with the annular flange, which is in turn preferably made of a single body with the lateral wall of the container body.
  • the container body of the capsule can be advantageously obtained as an entirety, in a relatively simple and economic manner.
  • a capsule 100 typically a disposable capsule, for preparing beverages, for example hot beverages such as coffee, tea, infusions or the like.
  • the capsule 100 is suitable to contain a dose of a food substance, for example but not necessarily powder coffee, which is suitable to obtain the aforementioned beverage by interacting with the process liquid, typically water.
  • a food substance for example but not necessarily powder coffee
  • the process liquid is a hot liquid, i.e. heated at a temperature above the room temperature.
  • the interaction between the food substance and the process liquid can for example be an infusion, a percolation or a solubilisation.
  • the capsule 100 is intended to be inserted into a special machine (not fully illustrated in the attached figures).
  • This machine comprises an extraction unit 300 (see fig. 5 ), which is generally configured for injecting the process liquid, typically at a pressure above the atmospheric pressure, in the capsule 100 and allow the outflow of the beverage thus obtained.
  • the extraction unit 300 may comprise a seat 305 for receiving the capsule 100 and an abutment body 310 suitable to block the capsule 100 in said reception seat 305.
  • the reception seat 305 can be delimited by a substantially tubular-shaped jacket 315, for example cylindrical or frusto-conical, which extends, for example with axially symmetric geometry, around a pre-set longitudinal axis A.
  • a substantially tubular-shaped jacket 315 for example cylindrical or frusto-conical, which extends, for example with axially symmetric geometry, around a pre-set longitudinal axis A.
  • An axial end 320 of the jacket 315 can be vacant, leaving the reception seat 305 open, while the opposite axial end can be closed by a bottom wall 325.
  • the bottom wall 325 can be obtained as a single body with the jacket 315, basically obtaining a substantially drinking-glass-shaped single body.
  • the abutment body 310 is positioned along the longitudinal axis A and it is faced to the vacant axial end 320 of the jacket 315, so as to be able to close the reception seat 305.
  • the abutment body 310 and the jacket 315 are mutually moveable in the direction parallel to the longitudinal axis A, between a closing position, in which the abutment body 310 is arranged at the vacant axial end 320 of the jacket 315, and an opening position, in which the abutment body 310 is spaced with respect to the vacant axial end 320 of the jacket 315, to allow the insertion and the removal of the capsule 100.
  • the relative displacement between the closing and opening position can be obtained by means of special displacement members which are actuated manually.
  • the capsule 100 comprises a container body 105, which can for example be drinking-glass-like shaped and it is suitable to contain a dose of the food substance.
  • the container body 105 can be made of plastic, for example but not necessarily polylactic acid (PLA).
  • PLA polylactic acid
  • the container body 105 is obtained by means of thermoforming, but it cannot be rules out that it can be obtained through other plastic material forming and/or moulding processes.
  • the container body 105 may comprise a substantially tubular-shaped lateral wall 110, for example cylindrical or frusto-conical, which extends, for example with axially symmetric geometry, around a pre-set longitudinal axis X.
  • the lateral wall 110 delimits an inner cavity 115, which can be opened at a vacant axial end 120 of the lateral wall 110, while, at the opposite axial end, it can be closed by a bottom wall 125.
  • the bottom wall 110 has a shape at least slightly tapered along the longitudinal axis X, for example frusto-conical, which narrows progressively starting from the vacant axial end 120 towards the bottom wall 125.
  • the bottom wall 125 can be obtained as a single body with the lateral wall 110.
  • the bottom wall 125 is illustrated - by way of example - as a continuous and solid wall.
  • the bottom wall 125 could be drilled, for example at a central portion thereof, and these holes could be sealed by means of a removable or drillable sealing film, for example aluminium, which would be fixed by means of gluing or sealing on the outer side of the bottom wall 125.
