Definitions

  • the present invention relates to a dispensing assembly for machines for making infusions in general, particularly espresso coffee.
  • dispensing assemblies In machines for making infusions in general and in particular for making espresso coffee, several types of dispensing assemblies are used which, according to the type, can use rigid capsules, pellets or pods.
  • the pod which is made of a material that is permeable to water, is placed in an infusion chamber which is crossed by a stream of water, which by filtering through the pod extracts its aromas, thus obtaining the desired infusion.
  • adapted extraction means are not provided, for example if the expulsion of the pod occurs by gravity, as a consequence of the sticking of the pod to the walls of the infusion chamber the pod cannot be expelled and thus replaced with a new capsule.
  • the aim of the present invention is to provide a dispensing assembly that does not suffer the above mentioned drawbacks, overcoming the limitations of the background art.
  • an object of the present invention is to provide a dispensing assembly that is structurally simple and that can be actuated easily.
  • Another object of the present invention is to provide a dispensing assembly that can be obtained easily starting from commonly commercially available elements and materials and is also competitive from a purely economic standpoint.
  • a dispensing assembly for machines for making infusions in general, particularly espresso coffee, comprising a supporting body which defines a channel for inserting a pod for making an infusion or the like, said insertion channel leading into an infusion assembly, which defines a first infusion chamber part and is connected to translation means for moving said infusion assembly against an abutment element, which defines a second infusion chamber part, and for retaining said pod in an infusion chamber defined by the joining of said first infusion chamber part with said second infusion chamber part, said infusion chamber being connected to at least one dispensing nozzle, characterized in that it comprises automatic means for the expulsion of said pod which are provided on each one of said infusion chamber parts for the separation and expulsion of said pod from said infusion chamber parts following the mutual spacing of said infusion chamber parts by way of said translation means.
  • Figure 1 is a sectional view of the dispensing assembly according to the invention, taken along a longitudinal plane thereof, during the insertion of a pod;
  • Figure 2 is a sectional view of the dispensing assembly according to the invention, taken along a longitudinal plane thereof, with the pod inserted therein;
  • Figure 3 is a sectional view of the dispensing assembly according to the invention, taken along a longitudinal plane thereof, during infusion;
  • Figure 4 is a sectional view of the dispensing assembly according to the invention, taken along a longitudinal plane thereof, during the expulsion of the previously infused pod;
  • Figure 5 is a sectional view of the dispensing assembly according to the invention, taken along a longitudinal plane thereof, ready to receive a new pod with which a new infusion is to be obtained.
  • the dispensing assembly for machines for making infusions in general, particularly espresso coffee comprises a supporting body 2 which is usually made of plastic material and defines a channel 3 for inserting a pod 4 which contains the powder and/or the substances for providing the desired infusion.
  • the pod 4 in a per se known manner, has a disk-like shape and is provided by a water-permeable enclosure.
  • An infusion assembly leads into the insertion channel 3 and in a per se known manner has an infusion piston 6, which is connected to a duct 7 for delivering water to provide the infusion.
  • the infusion assembly 5, which defines a first infusion chamber part 8 is connected to translation means 9 for the movement of the infusion assembly 5 against an abutment element 10, which defines a second infusion chamber part 11.
  • the first infusion chamber part 8 by moving toward the second infusion chamber part 11 traps, together with the latter, the pod 4 in an infusion chamber 12 that is defined by the joining of the two infusion chamber parts 8 and 1 1.
  • the water that arrives from the delivery duct 7 invades the infusion chamber 12, filtering into the pod 4 and exiting through a delivery channel 13, which is defined in the abutment element 10 and connects the infusion chamber 12 to at least one dispensing nozzle, not shown.
  • the dispensing assembly 1 shown in the figures belongs to the type of dispensing assemblies with insertion of the pod 4 from above by gravity.
  • the insertion channel 3 and the discharge channel 15 of the pod 4, which is consecutive to the insertion channel 3, are in fact substantially vertical so as to allow the insertion and discharge of the pod 4 to occur by gravity.
  • the translation means 9 the function of which, as already mentioned, consists in moving the two infusion chamber parts 8 and 11 closer in order to transfer the pod 4 from the insertion channel 3 into the infusion chamber 12, act directly on the infusion piston 6, which can slide with respect to a bush-shaped portion 16 which is defined by the supporting body 2.
  • the translation means 9 are advantageously provided by means of a cam element 17, which is associated with a rotation pivot 18 which engages slots which are arranged mutually opposite on the supporting body 2.
  • the cam element 17 has a resting surface 17a for positioning the infusion piston 6 outside the insertion chamber 3 in order to allow the insertion of the pod 4 and a second actuation surface 17b for pushing the first infusion chamber part 8 toward the second infusion chamber part 1 1 , so as to trap the pod 4 in the infusion chamber 12.
  • the cam element 17 can be actuated by means of an external lever 20, which protrudes in the upper part of the dispensing assembly 1 so that it can be gripped by a user for the movement of the first infusion chamber part 8 toward and away from the second infusion chamber part 11.
  • adjustment means are provided which produce the translation of the rotation pivot 18 along the translation direction of the infusion piston 6, which will not be described in detail.
  • automatic means 23 for expelling the pod 4 are comprised and are provided on each one of the infusion chamber parts 8 and 11 for the separation and expulsion of the pod 4 from the infusion chamber parts 8 and 11 following their mutual spacing by way of the translation means 9 described earlier.
  • the automatic expulsion means 23 comprise, for each infusion chamber part 8 or 11 , a cap-like element 24, which is made of a nonstick elastically deformable material which is hygienically adapted for making contact with food.
  • each cap-like element 24 is fitted on a respective infusion chamber part 8 or 11 so as to define an elastic membrane 25 which is directed toward the other infusion chamber part 8 or 11 and delimits the internal volume of each infusion chamber part 8 or 11.
  • the elastic membranes 25, by deforming elastically due to the approach of the infusion assembly 5 to the abutment element 10, with the pod 4 interposed, adhere to the inner surfaces 22 of the two infusion chamber parts 8 and 11, and once the spacing of the infusion assembly 5 from the abutment element 10 has occurred, by recovering their initial geometry they expel the pod 4 from the infusion chamber 12, leaving it free to fall into the discharge channel 15.
  • the two cap-like elements 24 also act as gaskets for the two infusion chamber parts 8 and 1 1, ensuring a correct seal of the entire dispensing assembly 1.
  • the elastic membranes 25 of the two cap-like elements 24 have a plurality of holes 26.
  • the cap-like elements 24 described above are made of materials that are selected from the group constituted by silicone rubbers, natural rubbers, polyisoprene-based rubbers, nitrile-based rubbers, butadiene-acrylonitrile-based rubbers, ethylene-propylene-diene monomer- based rubbers, chloroprene-based rubbers and rubbers based on tetrafluoroethene-perfluoropropene-vinylidene fluoride.
  • the pod 4 is introduced and discharged respectively in and from the dispensing assembly 1 by gravity.
  • a lower partition 27 is provided, which is defined at the inlet of the discharge channel 15 in the direction of the fall of the pod 4 in order to close the discharge channel 15 and support the pod 4 at the two infusion chamber parts 8 and 11.
  • the lower partition 27 can be associated kinematically with the translation means 9 at least for the opening of the discharge channel 15, so as to allow the discharge of the pod 4 once the infusion has been obtained.
  • the lower partition 27 is associated slidingly with the supporting body 2 transversely to the discharge channel 15 and comprises a first substantially flat portion 27a, which is adapted to affect the pod 4 at the inlet of the discharge channel 15, and a second portion 27b, which has a first engagement tooth 28, which can engage by snap action a second engagement tooth 29 which is integral in translation with respect to the infusion piston 6.
  • the lower partition 27 can move between an inactive position, in which the pod 4 is affected by the first portion 27a, and a retracted position, in which the pod 4 is free to fall along the discharge channel 15.
  • elastic return means 30 which consist for example of a helical spring 31 which is interposed between the lower partition 27 and the infusion piston 6, and are adapted for the return of the lower partition 27 to its inactive position.
  • means are provided for disengagement on command which are associated with the infusion piston 6 and can be actuated manually by the user to disengage the first engagement tooth 28 from the second engagement tooth 29.
  • the materials used may be any according to requirements.
