Description

DISPENSING ASSEMBLY FOR MACHINES FOR MAKING INFUSIONS IN GENERAL, PARTICULARLY ESPRESSO COFFEE
The present invention relates to a dispensing assembly for machines for making infusions in general, particularly espresso coffee.
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.
Usually, in pod-using dispensing assemblies, 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.
Once the infusion has been obtained, particular extraction means, if provided, expel the pod from the infusion chamber, which is usually defined by two distinct half-shells which can be moved mutually closer with the pod interposed between them.
These dispensing assemblies of the known type are not devoid of drawbacks, which include the fact that as a consequence of the pressure applied by the two half-shells on the pod, following the impregnation of the pod with water, and due to the material of which the pod is made, the pod sticks to the inner walls of the infusion chamber to the point that under the action of the extraction means it can suffer tears of different types, which lead to the scattering of the substances contained therein within the dispensing assembly.
Another drawback of known types of dispensing assemblies, linked to the one described above, resides in that as a consequence of the tearing of the pod because it has stuck to the walls of the infusion chamber, parts of the pod remain stuck to the walls, blocking the nozzles through which the hot water is generally injected, consequently altering the correct operation of the dispensing assembly.
If 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.
This inevitably leads to an extraordinary maintenance operation on the dispensing assembly on the part of assigned personnel.
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.
Within this aim, 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.
This aim, as well as these and other objects which will become better apparent hereinafter are achieved by 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.
Further characteristics and advantages will become better apparent from the description of a preferred but not exclusive embodiment of a dispensing assembly for machines for making infusions in general, particularly espresso coffee, illustrated by way of non-limiting example in the accompanying drawings, wherein:
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.
With reference to the figures, the dispensing assembly for machines for making infusions in general, particularly espresso coffee, according to the invention, generally designated by the reference numeral 1 , 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, generally designated by the reference numeral 5, 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.
More precisely, 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.
In this manner, as will become better apparent hereinafter, 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.
In this manner, 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.
More specifically, 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.
As regards 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.
In order to be able to adapt to the different dimensions of the pod 4 in terms of axial length, while always ensuring the seal with respect to the first infusion chamber part 8 and with respect to 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.
According to the invention, 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.
Advantageously, 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.
More specifically, 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.
In this manner, 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.
Moreover, 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.
Conveniently, in order to allow the flow of water through the pod 4, the elastic membranes 25 of the two cap-like elements 24 have a plurality of holes 26.
Preferably, 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.
As already mentioned, in the dispensing assembly 1 according to the invention the pod 4 is introduced and discharged respectively in and from the dispensing assembly 1 by gravity.
In order to affect the pod 4 during its fall, so as to keep it in the correct position during the approach of the two infusion chamber parts 8 and 11 , 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.
Moreover, 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.
More precisely, 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.
In this manner, 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.
This mobility occurs in contrast with, and due to the action of, 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.
More precisely, in order to allow such return, 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.
From what has been described above it is thus evident that the invention achieves the intended aim and objects, and in particular the fact is stressed that a dispensing assembly for machines for providing infusions in general, particularly espresso coffee, is provided in which non-stick membranes operate which lead to the assured separation of the pod from the walls of the infusion chamber in a simple, safe and efficient manner.
The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
All the details may further be replaced with other technically equivalent elements.
In practice, the materials used, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to requirements.

Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
