    P/00/011 28/5/91 AUSTRALIA Patents Act 1990 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Name of Applicant: MACCHIAVELLI S.r.L. Actual Inventor: Raffaele Rondelli Address for service is: Goija Haines & Friend PO Box 1417 West Leederville Western Australia 6901 Attorney Code: IJ Invention Title: Interchangeable Capsule for the Preparation of an Infusion of a Powdered Product, and Relative Method for Obtaining such an Infusion The following statement is a full description of this invention, including the best method of performing it known to me:- 2 "INTERCHANGEABLE CAPSULE FOR THE PREPARATION OF AN INFUSION OF A POWDERED PRODUCT, AND RELATIVE METHOD FOR OBTAINING SUCH AN INFUSION" 5 The present invention concerns an interchangeable capsule for the preparation of an infusion of a powdered product, e.g. coffee or the like. The present invention further concerns a method for obtaining an infusion of said powdered product. 10 In particular, the present invention concerns the preparation of the so called "American coffee". Incidentally, although the present invention finds an advantageous but not exclusive application to interchangeable capsules for the preparation of an infusion 15 of "American coffee" (to which the following description will explicitly refer, without ever losing its general character), the teaching of the present invention can be applied to any kind of interchangeable capsule, e.g. to interchangeable capsules for espresso, tea, chamomile tea, 20 etc. As already known, the so called "American coffee" is an infusion made by means of a particular machine wherein the hot water passes through a filter containing ground unpressed coffee and settles by gravity in an underlying 25 pot. The coffee used for the preparation of such a drink is 3 different from the one used by mocha machines or machines for Italian espresso because it is more roughly ground and it is not subjected to any pre-compression when it is in the capsule. 5 Some machines, which are presently commercially available, have been expressly designed for the preparation of American coffee and are characterized by a very simple operation. In fact, these machines have a water tank, a pump 10 sending heated water inside a small container provided with a paper filter containing coffee. The hot water submerges the coffee and, passing through the paper filter, falls by gravity into the dedicated underlying pot which is suited to keep the drink hot for a long time because it is heated 15 by a special electrical resistance. Besides traditional American coffee machines, wherein the cone-shaped filter is manually filled by the user, capsules having an outer casing containing a paper filter partially filled with unpressed coffee have recently 20 appeared on the market. By means of suitable percolator machines, the plastic lid and the plastic bottom are pierced in order to create a hot water flow infusing the coffee powder. However, the capsules which are presently commercially 25 available are not completely reliable. In fact, since they usually have only one filter in the bottom, the incoming 4 hot water is induced to flow along substantially vertical preferential fluid threads which, therefore, do not involve the whole mass of powdered product contained in the capsule. 5 Therefore, the main object of the present invention is to provide an interchangeable capsule for infusions wherein the path of the infusing water inside said capsule is as long and as winding as possible in order to delay the infusion times and in order to involve the largest possible 10 amount of product. A further object of the present invention is to provide an innovative method for obtaining such an infusion. According to the present invention, therefore, an 15 interchangeable capsule is produced according to the content of claim 1 or of any of the claims directly or indirectly dependent on claim 1. Always according to the principles of the present invention, it is provided an innovative method for 20 obtaining an infusion of a powdered product according to the content of claim 10 or of any of the claims directly or indirectly dependent on claim 10. For a better understanding of the present invention it is described hereinafter an embodiment given for mere 25 illustrative and not limitative purposes, with a reference to the annexed figures, wherein: 5 - figure 1 shows a 3D view of an interchangeable capsule for a powdered product according to the present invention; - figure 2 shows a first longitudinal section of the 5 capsule of figure 1; - figure 3 shows a 3D view from above of a container for the powdered product belonging to the capsule according to figures 1 and 2; - figure 4 shows a 3D view from below of the container 10 of figure 3; - figure 5 shows a side view of the container shown in figures 3 and 4; - figure 6 shows a back view of the container shown in figures 3, 4, 5; 15 figure 7 shows a front view of the container shown in figures 3, 4, 5, 6; - figure 8 shows a 3D view from below of a lid belonging to the capsule according to figures 1 and 2; this lid, in use, is coupled to the container in order to form 20 the capsule shown in figures 1, 2; - figure 9 shows a side view of the lid of figure 8; and - figure 10 shows a plan view of the lid of figure 8. The enclosed figures show a preferred embodiment of an 25 interchangeable capsule 100 produced according to the principles of the present invention.
    6 The interchangeable capsule 100 is suited to contain inside it a certain amount of a powdered product (e.g. coffee) for preparing an infusion, in particular, an "American coffee" according to the above definition. 5 The interchangeable capsule 100 comprises a container 101 closed by a lid 102 by means of known methods. The container 101 comprises, in turn, a bottom 101A advantageously but not necessarily produced in one piece with the side wall 101B. 10 It must be noticed that an axis (X) passes through the bottom 101A, said axis substantially lying on a plane (n), which defines a substantially horizontal direction. Moreover, in the present description, any "substantially horizontal" element, body or device is an 15 element, body or device substantially lying on the plane (n) . Obviously, also elements bodies or devices substantially lying on any plane parallel to plane (r) must be considered "substantially horizontal". As shown in figure 2, the side wall 101B shows a 20 central vertical axis of symmetry (Y) which is perpendicular to the aforesaid axis (X). Therefore, in the present description, any "substantially horizontal" element, body or device is an element, body or device substantially extending according 25 to the direction defined by axis (Y). The side wall 101B has the usual substantially 7 truncated-cone shape, flared upwards. An annulus-shaped support edge 104 protrudes from the upper end 103 of the container 101 so that the whole interchangeable capsule 100 can be received in a special 5 housing created in a percolator machine (not shown). Preferably, but not necessarily, the bottom 101A, the side wall 101B and the support edge 104 are made in one piece of a suitable plastic material for foods of a known type. The outer surface of the side wall 101B could also be 10 provided with some ribs 105 (figure 1) to strengthen the structure of said side wall 101B. As shown in particular in figure 2, a feeding well 110 protrudes from the lid 102 towards the inside of the container 101. 15 As shown in greater detail in figure 8, the bottom 111 of the feeding well 110 is provided with three spokes 112 whereon, in use, a filter 113 (figure 2) is fastened, said filter allowing the passage of hot water from the feeding well 110 to the inside of the container 101, but not the 20 other way. In other words, the filter 113 acts as separating element between the hot water coming from the feeding well 110 and the infusion inside the container 101. In fact, a possible accidental reflux of the infusion towards the feeding well 110 is prevented by the fact that 25 the hot water pressure inside the feeding well 110 is obviously always higher than the infusion pressure in the 8 container 101, a depression being present outgoing from the capsule 100. As shown in particular in figure 2, below the feeding well 110 there is a small tank 120 (also having an axis 5 (Y)) supported by the bottom 101A of the container 101 by means of a cup-shaped support device 130 coaxial to the small tank 120. The support device 130, having a transverse size larger than that of the small tank 120, is arranged outside 10 said small tank 120. In particular, the small tank 120 has a circular shaped bottom which is transverse to the incoming water jet whose direction and orientation are defined by an arrow (Fl). In other words, the bottom 121 represents a 15 deflecting device (transverse to axis (X)), substantially horizontal, of the infusion jet, substantially vertical, whose direction and orientation are defined by the arrow (Fl). Besides bottom 121, the small tank 120 comprises a truncated-cone-shaped side wall 122. 20 After the impact with the bottom 121, the infusion liquid jet (therefore already comprising a certain amount of the product infused in hot water) is horizontally and radially deflected according to directions and orientations defined by the arrows (F2). 25 In the embodiment shown in the enclosed figures, the small tank 120 is raised with respect to the plane (n) in 9 order to form an underlying chamber 140, which will be useful for reasons better explained hereinafter. More precisely, the chamber 140 is defined from above by the bottom 121 and laterally by a lower truncated-cone 5 shaped portion 131 of the support device 130. As shown in figure 2, a toroidal space 150 is defined between the inner wall of an upper portion 132 of the support device 130 and the outer wall of the small tank 120, said space being in hydraulic communication with the 10 chamber 140 by means of an annulus-shaped passage 151. Advantageously, but not necessarily, the upper portion 132, substantially cylindrical, of the support device 130 is provided with a plurality of indentations 133. 15 Between each pair of indentations 133 it is therefore defined a related through opening 134 allowing the outflow of the infusion. Obviously, the width of each through opening 134, advantageously shaped like an indentation, has been 20 calculated in order to prevent, as far as possible, the passage of granules of ground product dragged by the hot infusion. The indentations 133 and the openings 134 form together first vertical filtering means (FT1) suited to 25 filter the infusion (see hereinafter). Also the wall 122 of the small tank 120 comprises a 10 full lower portion 123 and an upper portion 124 possibly provided with a plurality of indentations 125. Between each pair of indentations it is defined a related through opening 126 allowing the passage of the hot water/powdered 5 product infusion. The indentations 125 and the openings 126 form together second vertical filtering means (FT2) suited to filter the infusion of powdered product outgoing from the small tank 120 (see hereinafter). 10 Obviously, also in this case the width of each through opening 126, advantageously shaped like an indentation, has been calculated in order to prevent, as far as possible, the passage of granules of ground product dragged by the hot infusion. 15 In short, it can be stated that the present invention comprises all possible combinations between first vertical filtering means (FT1) and second vertical filtering means (FT2). At least one of two vertical filtering means (FT1), (FT2) is present. Therefore, only first vertical filtering 20 means (FT1), or only second vertical filtering means (FT2), or both vertical filtering means (FTl), (FT2) can be present. The choice of kind of filtering means, their allocation and their structure, in terms of indentations 25 and through openings, is made by the manufacturer of the interchangeable capsule 100 before starting the production 11 of the same according to the chemical and physical properties of the powdered product which will be the base of the infusion. Advantageously, but not necessarily, the annulus 5 shaped passage 151 is provided with a further filter 152 (made of paper, felt, etc.) in order to filter further the percolating liquid before it enters the chamber 140. The mass of powdered product (MC) is present both in the space defined between the inner wall of the container 10 101 and the outer wall of the support device 130 and inside the small tank 120. Furthermore, advantageously but not necessarily, the chamber 130 is at least partially filled by a waffle containing at least one more essence, such as cardamom, 15 cinnamon or ginseng. The present capsule 100 works as follows: a) the pressurized hot water enters the container 101 from the feeding well 110, after having passed through filter 113, according to the direction and orientation 20 indicated by the arrow (Fl); b) immediately after having passed through filter 113, the hot water meets the powdered product (MC) arranged between the feeding well 110 and the small tank 120; the product/hot water infusion liquid starts to be formed; 25 c) this infusion liquid hits the bottom 121 of the small tank 120 and is horizontally and radially deflected 12 according to the directions and orientations of the arrows (F2); d) in case second vertical filtering means (FT2) are provided, a first portion of the infusion liquid passes 5 immediately through the openings 126 of second vertical filtering means (FT2) for flowing towards the toroidal space 150 (arrows (F3)); from this toroidal space 150 the infusion flows towards the chamber 140 after having possibly been filtrated by the filter 152; passing through 10 the waffle, in case present in the chamber 140, the infusion takes the taste of the substance contained by the waffle; e) a second portion of the infusion liquid is deflected according to directions and orientations given by 15 the arrows (F4) in order to involve also the mass of powdered product (MC) arranged in the space defined between the container 101 and the support device 130; f) in case also first vertical filtering means (FT1) are present, the infusion will be deflected according to 20 the directions and the orientations given by the arrows (FS) to pass through the openings 134 and to converge to the toroidal space 150 together with the infusion whose origin is indicated by the arrows (F3); g) the infusion according to the arrow (F3) and the 25 infusion according to the arrow (F5), joined together in the toroidal space 150, undergo a further filtering 13 operation by means of the filter 152; the final infusion (arrow (F6)) is therefore enriched with an essence possibly present in the chamber 140 and is sent to the final user. In another embodiment, not shown, the pressurized hot 5 water enters the container, not through the well 110 but through a hole pierced in the lid 102 by known means. The present invention also refers to a method for obtaining an infusion, in particular an American coffee; the method is characterized by the following steps: 10 (fl) centrally and vertically injecting a given amount of hot water into a container of the powdered product; (f2) causing at least part of the hot water to be deflected in a substantially horizontal direction by a front element which the hot water hits head-on along its 15 path; (f3) filtering the infusion in said substantially horizontal direction by causing it to pass through substantially vertical filtering means; (f4) causing the filtered infusion to converge towards 20 a collection chamber; (f5) causing the filtered infusion to flow towards a receptacle. The method can further comprise a further filtering step of the outgoing infusion. 25 Moreover, the method can comprise a further step wherein the infusion passes through means containing at 14 least an essence, such as cardamom, cinnamon or ginseng. The advantages of the disposable capsule object of the present invention are as follows: - the capsule object of the invention has, preferably 5 but not necessarily, a central well through which the hot water outgoing from a single jet of the machine flows; therefore, the hot water is evenly distributed in the mass of ground product; this feature allows an even and constant control of the water distribution in the capsule; 10 - the bottom of the capsule, or better to say, the bottom of the space containing the powdered product, is closed, thus avoiding preferential vertical water outflows during the infusing step, as is the case with the other known capsules having a filter in the bottom or a single 15 opening produced by piercing the bottom itself; - the infusion filtering area is substantially vertical in order to obtain a larger filtering area if compared to the capsules having only a coffee filter arranged in the bottom; moreover, this vertical filtering 20 creates a turbulence effect, thus improving the exploitation of the product to be infused; - the capsule object of the present invention allows the production of several different products by calibrating the water inlet and the product outlet according to the 25 product itself; - the capsule objet of the present invention allows to 15 contain larger volumes of product though maintaining equal filtering capacity; - the capsule is advantageously produced in one piece with several sections, thus allowing the use of a simpler 5 packaging machine for the industrialization of the capsule; - in the industrialization step, the capsule object of the present invention allows to carry out a central dosing, thus simplifying the related packaging machines; and - the structure of the capsule object of the present 10 invention creates inside it a winding liquid path, thus allowing the maximum exploitation of the contained infusion.
