Definitions

  • the present invention relates to a device for making infusions.
  • 'Moka' coffee maker having a boiler, an element in which ground coffee is inserted, and a filter- equipped container, located above the boiler, into which the fluid, once heated up, is automatically decanted, transiting through the filter and thereby releasing the aroma of the coffee powder into the fluid.
  • the specific support used in the 'Moka' coffee maker allows to house the coffee powder thereinside. During the heating of the water an entailed pressure increase takes place inside the boiler, allowing water to rise and flow through the section of the container in which the coffee is housed, until reaching the top container.
  • the making of tea or of any other herbal infusion should use suitable boilers, and anyhow cannot take place inside such a 'Moka' coffee maker.
  • the technical problem underlying the present invention is to provide a device for making different kinds of hot beverages, allowing to overcome the drawbacks mentioned hereto with reference to the known art.
  • the present invention provides several relevant advantages.
  • the main advantage lies in that a plurality of beverages may be made with the use of a single device, regardless of the nature of the infusion material, be it in powder or in leaves.
  • Figure 1 is an exploded perspective view of a device for making infusions according to the present invention
  • Figures 2 A and 2B are a perspective view and a side section view, respectively, of a filter and of a cup-shaped body used in the device for making infusions according to the present invention, details of Figure 1;

  • a device for making infusions comprises a boiler 1, a container 3 in which the beverage, once made, is housed, a filter 4, and a cup-shaped body 2. Moreover, according to a preferred embodiment there is a gasket 5, apt to be interposed between the container 3 and the boiler 1.
  • the boiler 1 is cup-shaped, preferably substantially cylinder-shaped, and it has a bottom wall 12 that may be widened to ensure an improved resting onto the heat source with which it will be in contact for heating and making the beverage with the modes that will be described hereinafter.
  • the boiler 1 further comprises a safety valve 13, illustrated in Figure 3, in order to avoid a dangerous excess of pressure therein.
  • the two threads 11, 31 form a threaded coupling that allows, by using the gasket 5 at the filter 4, interposed between the boiler 1 and the container 3, to hold the seal inside the device according to the present invention.
  • the threaded coupling 11, 31 may be replaced by any other connection means, e.g. a bayonet system.
  • the container 3 further comprises a handle 33, a spout 34 for pouring the made beverage and a lid 35.
  • the container 3 has a base 32 at the center of which there is an elongate portion 36.
  • a port that, referring to Figure 4, faces onto the boiler 1 and, at the opposite end thereof, a further port from which the fluid may exit toward the inner portion of the container 3.
  • the cup-shaped body 2 which in the present embodiment is substantially cylinder-shaped and has an elastic bottom 21 at a first end thereof, whereas at the opposite end thereof it has an open end 22.
  • the cup-shaped body 2 is apt to be inserted upturned, i.e. the open end 22 thereof being placed at the bottom wall 12 of the boiler 1, whereas the elastic bottom 21 faces the thread 11.
  • the cup-shaped body has a plane section of smaller dimensions with respect to the boiler 1, in a manner such as to be capable of being inserted inside the latter, as well as of defining an interspace 14 apt to the transit of the beverage.
  • the interspace 14 is comprised between the external side surface of the cup-shaped body 2 and the internal wall of the boiler 1.
  • the filter 4 having dimensions ranging from those of the diameter of the male thread 11 and of the female thread 31 , so that, by placing the gasket 5 about the filter 4, the latter is blocked between the boiler 1 and the container 3 by means of the closing of the threaded fit.
  • the filter 4 has a foraminated surface 42, in which the foramina preferably have a size such as to prevent the transit of the infusion material, which thus may not reach the container 3 from the boiler 1.

  • the open end 22 of the cup-shaped body 2 is held in contact with the bottom wall 12. Therefore, the water and the infusion material 6, once inserted, cannot get out of the region 23.
  • the dimensions of the cup-shaped body 2 are such that when it is inserted in the boiler 1 the former extends to a position proximal to the thread 11, compatibly to the presence of the filter 4 and of the contact element 41. It is advisable that the contact element 41 has the smallest viable longitudinal extension, so as to leave more space to the cup-shaped body 2 and accordingly leaving defined a region 23, apt to contain the water and the infusion material 6, of larger dimensions.
  • the contact element 41 is apt to let easily remove the filter 4, held by the gasket 5, once said filter is inserted onto the thread 31 of the container 3. Usually, it is absolutely necessary to use a knife, or another pointed tool, onto the traditional coffee-maker filter in order to prize it out and remove it, whereas the presence of the contact element 41 allows to avoid such a hazardous operation.
  • the elastic bottom 21 centrally has a seat 24, apt to house the contact element 41 in order to foster the contact of the latter and position the cup-shaped body precisely at the center of the filter 4 and of the boiler 1.
  • the bottom wall 12 is round-shaped, in a manner such as to be capable of centering the cup-shaped body 2 also at the open end 22 thereof.
  • the seat 24 and the round shape of the bottom wall 12 act as means for centering the cup-shaped body 2 with regard to boiler 1.
  • the beverage should flow through the interspace 14, then transit through the filter 4, and flow into the container 3 to get to the elongate portion 36, and lastly to outpour onto the base 32 inside the container 3.
  • the water and the infusion material 6 are inserted inside the region 23. As in this first stage the water and the infusion material 6 should not be present inside the interspace 14, first of all the cup-shaped body 2 has to be filled.
  • the cup-shaped body 2 should be upturned with respect to the working configuration; hence, it shall have the open end 22 upward and the elastic bottom 21 downward. Thus, it may be filled with water and infusion material 6.
  • the cup-shaped body 2 further comprises means for metering, which in the present embodiment is a groove 25 obtained about the sidewall of the cup-shaped body.
  • the cup-shaped body could be filled up to the mark indicated by the groove 25, and ensure a precise amount of water.
  • the groove 25 improves the structural stiffness of the cup-shaped body, limiting the deformability thereof.
  • the boiler 1 is upturned and inserted, in this configuration, onto the cup-shaped body 2, after having filled the latter with water and infusion material 6, holding it also upturned.
  • the boiler 1, with the cup-shaped body 2 therein, is returned to a standing position, taking care that the open end 22 remains in contact with the bottom wall 12, to prevent water spilling.
  • the boiler 1 it suffices to exert a light pressure with a finger onto the elastic bottom 21.
  • the filter 4 is positioned, with the contact element 41 housed in the suitable seat 24, the gasket 5, and lastly the device is closed, by screwing on the container 3.
  • the pressure acts onto the internal surface of the cup-shaped body 2, and in particular against the elastic bottom 21 , pressing upward the cup-shaped body 2.
  • the contact element 41 prevents the cup-shaped body 2 from lifting.
  • the elastic bottom 21 is constrained exclusively in the central zone thereof, basically that corresponding to the seat 24. Upon attaining a sufficient pressure, the elastic bottom 21 will flex against the contact element 41.
  • the elastic bottom 21 exhibits mechanical features, linked to its thickness and to the kind of material used therefor, giving it sufficient elasticity to be capable of being indexed owing to the action of the pressure internal to the region 23.
  • the elastic bottom undergoes a strain that may be schematized as that undergone by a centrally constrained disc onto which an uniform pressure acts, thereby exhibiting a strain in the direction along which the pressure acts, nil at the center and increasing until the external periphery of the disc.
  • a strain that may be schematized as that undergone by a centrally constrained disc onto which an uniform pressure acts, thereby exhibiting a strain in the direction along which the pressure acts, nil at the center and increasing until the external periphery of the disc.
  • the strain of the elastic bottom 21 be such that the lifting of the open end 22 suffices to let transit therethrough the fluid, but not the infusion material 6.
  • a filtering action occurs that anyhow could be carried through, should a fraction of the material 6 escape, by means of the filter 4.
  • the action of the filter 4 is not essential, as the filtering of the cup- shaped body 2 already suffices to the complete separation of the beverage from the infusion material 6.
  • the filter 4 may alternatively be replaced by a non-filtering component capable of supporting the contact element 41.
  • a non-filtering component capable of supporting the contact element 41.
  • the filter 4 contains a ' -peripheral portion, and spokes centrally uniting to support the contact element 41.
  • the strain and therefore the lifting of the open end 22 is a function of the pressure internal to the region 23, which in turn is linked to the temperature of the water therein, and to the infusion time.
  • the internal pressure begins to rise, at constant temperature, until having attained the pressure required to sufficiently strain the elastic bottom 21.
  • the fluid Upon reaching the interspace 14, the fluid rises toward the filter 4 and the container 3, pushed both by capillarity and by the action of the pressure, until getting to the elongate portion 36, where it is poured onto the container 3.
  • the infusion time By means of a correct sizing of the elastic bottom 21 and a correct selection of the materials, there may be accurately set the infusion time, considering a predetermined heat source.
  • the strain of the elastic bottom 21 is a function of the infusion time; i.e., an elastic bottom 21 with an elevated structural rigidity, requires a longer time period for the strain to take place, and such a time period corresponding to the infusion time of the material.
  • the exact size, as a function of the selected material, may be assessed from empirical tests, or optionally by exploiting the scheme described above for the elastic bottom 21, according to which the latter may be schematized as a disc rested onto the center, onto which an uniform pressure acts.
  • the boiler 1 and the container 3 may be those of a traditional 'Moka' coffee maker.
  • the shape of the boiler 1 in this case is not cylindrical anymore but frustopyramidal, with a generally hexagonal base. Since the cup-shaped body 2 should be capable of being inserted inside the boiler 1 and be free to lift therein, the former should anyhow be cylinder-shaped.
  • the boiler 1 having the shape of a pyramid and the cup-shaped body that of a cylinder, it is evident that the interspace 14 has a greater size at the bottom zone, nearer to the bottom wall 12. Therefore, in this case, though the operation of the device is anyhow ensured, there cannot be used all the fluid contained inside the region 23, as, unavoidably, some of the beverage will remain in the bottom region of the boiler 1.
