    • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to the number references of the above mentioned figures, the delivery head according to the present invention, which has been generally indicated by the reference number 1, can be applied to an espresso coffee machine, generally indicated by the reference number 2, including a base or bottom 3 and an upright 4.
  • Said upright comprises, in the inside thereof, driving devices designed for driving said espresso coffee machine, said driving devices including, in a per se known manner, a pressurized hot water source, supplying the delivery head.
  • According to the present invention, the delivery head 1 comprises a top supporting element 6, pivoted, through a pivot pin 30, to bottom supporting elements 5, in turn made rigid with the upright 4 of the coffee machine.
  • As shown, the top supporting element 6 comprises a top cover 8, and the bottom supporting element 5 likewise comprises a bottom cover 7.
  • The bottom supporting element 5 comprises moreover a recess 9 provided for housing, during the coffee delivery, and as it will become more apparent hereinafter, a ground coffee holding capsule 10.
  • An operating or driving lever 11 is pivoted, through a pivot pin 31, to the top supporting element 6 for driving it, so as to define at least two operating positions: a first position closed on the bottom supporting element for delivery coffee, and a second open position for loading and ejecting the coffee capsule 10.
  • The closed delivery position can be clearly seen in FIGS. 1, 3, 5 and 6, whereas the capsule loading and ejecting open position can be clearly seen in FIGS. 2 and 7.
  • More specifically, the delivery closed position is stably held so as to resist against the delivery pressure, by locking means including a locking lever 12 pivoted to the top supporting element 6 at a locking lever pin 13 and having a hook shaped portion 14, affecting a locking peg 15, rigid with said bottom supporting element 5.
  • According to the present invention, the delivery head 1 comprises delivery means, including perforating means for progressively perforating the coffee capsule 10.
  • In particular, said delivery means comprise a delivery nozzle 16, formed in the bottom supporting element 5, at an outlet hole formed in the bottom of the coffee capsule 10 housing recess 9.
  • In this position, according to the invention, is arranged a bottom perforating assembly 17, preferably of circular cross-section tapering configuration, adapted to perforate the bottom of the coffee capsule 10.
  • Such a perforation is obtained as the coffee capsule 10 is pressed against the bottom perforating assembly 17, under the pressure provided by an overheated water flow, introduced into said coffee capsule 10, and providing a downward directed pushing of the bottom wall of said coffee capsule 10 against the bottom perforating assembling or element 17.
  • The perforating means comprise moreover a top perforating assembly or element 18, having a quadrangular tapering cross-section, and being coupled to a support 19 for the top perforating element 18, in turn coupled to the top supporting element 6.
  • The support 19 for the top perforating element 18 comprises at least a delivery duct 20, adjoining the top perforating element 18, designed for delivery pressurized water coming from the pressurized water generating members of the coffee machine.
  • More specifically, the top perforating element or assembly 18 affects the top surface of the coffee capsule 10 to perforate it, as the head is closed, to allow pressurized water supplied by the delivery duct 20 to enter the capsule 10.
  • Said capsule 10 comprises an outer film element, which can be perforated by the top 18 and bottom 17 perforating elements or assemblies, and being provided with an inner rigid filtering construction holding the ground coffee powder.
  • At the top thereof, the filtering rigid construction of the coffee capsule or cartridge 10 comprises a plurality of channels allowing top water entering the hole formed by the top perforating element 18 to be distributed at the top.
  • Further, according to the present invention, the delivery head 1 comprises moreover coffee capsule 10 ejecting means, including a capsule ejecting fork element 21 pivoted to the pivot pin 30 applied to the bottom supporting element 5 and including an annular portion 22 designed for encompassing the top of the coffee capsule 10, which is suitably provided with a perimetrical bearing edge portion 23.
  • The delivery head 1 according to the present invention operates as follows.
  • At the start, the delivery head 10 is arranged in an open position, shown for example in FIG. 2, in a ready condition for receiving a coffee capsule or cartridge 10, which is partially engaged in the capsule recess 9, to locate the powder capsule near the bottom perforating assembly or element 17, without causing said perforating element 17 to perforate, at the start, the bottom surface of the coffee cartridge or capsule 10.
  • Then, the head 1 is closed by actuating the lever 11 under a downward pressure, to cause the top supporting element 6 to be closed on the bottom supporting element 5.
  • As the top supporting element 6 is closed on the bottom supporting element 5, said top supporting element 18 will perforate the top surface of the coffee capsule or cartridge 10.
  • Then pressurized water is delivered which, through the delivery duct 20 and the hole formed by the top perforating element 18 can enter the coffee capsule and diffuse therethrough owing to the provision of suitable channels formed inside said capsule 10.
  • Thus, the overheated water pressure will cause a further perforation of the bottom surface of the capsule by the bottom perforating element 17, thereby said bottom surface is pressed downward against the bottom perforating element 17 in a subsequent operating step, with respect to the perforation of the top surface of the coffee capsule 10.
  • In particular, water passes through the capsule 10 and exits the delivery nozzle 16 thereby providing the coffee beverage, which is collected in a cup or the like, not specifically shown.
  • At the end of the delivery operation, the top supporting element 6 is raised by operating the lever 11 pivoted to the pivot pin 31.
  • In particular, as the top supporting element 6 is raised, also the fork element 21 is raised owing to the provision of tooth elements formed on the fork element 21 and cooperating with respective slanted planes or surfaces of said top supporting element 6, which operate as linear cams 40.
  • Thus, the fork element 21 will rise said capsule 10, by its annular portion 22, which engages at the bottom thereof the bearing perimetrical edge portion 23 of the capsule 10.
  • Upon achieving a set inclination, as is clearly shown in FIG. 2, the capsule 10 will slide on the fork element 21 and, after having passed the annular portion 22, will fall inside the fork element 21 and, through a specifically designed passage, will be collected in a collecting vessel formed in the upright 2.
  • Then, as the mentioned inclination is exceeded, the tooth element of the fork 21 will be disengaged from the slanted surfaces of the top supporting element 6.
  • Accordingly, the fork element 21 can return to its starting position in which it abuts against the bottom supporting element 5.
  • The annular portion 22 thereof, in particular, will be arranged at the top edge portion of the capsule 10 recess 9.
  • Thus, the coffee machine will be ready for delivery a new coffee cup.
  • It has been found that the invention fully achieves the intended aim and objects.
  • In fact, the invention provides a delivery head for espresso coffee machines which is adapted to provide a perfect infusion of the coffee beverage, and, moreover, being of very easy and safe operation.
  • In practicing the invention, the used materials, and the contingent size and shapes can be any, according to requirements and the status of the art.
