Description
- The present invention relates to an interchangeable capsule to prepare an infusion of a powdered product, for example coffee or similar products.
- The present invention also relates to a method for obtaining an infusion of said powdered product.
- In particular, the present invention is directed to prepare the so-called “American coffee”.
- Incidentally, although the present invention has advantageous but not exclusive application to the interchangeable capsules to prepare an infusion of “American coffee” (to which the following description will make explicit reference without loss of generality), the teachings of the present invention may be applied to any type of interchangeable capsule for example to the interchangeable capsules for espresso coffee, tea, chamomile etc.
- As known, being defined as “American coffee” is an infusion obtained by the use of a particular machine wherein the hot water passes through a filter containing the grounded, un-pressed coffee and is deposited by gravity into an underlying carafe.
- The coffee that is used to prepare said beverage differs from that used in “moka” machines or Italian espresso by the fact of being coarsely ground and not being subjected to any pre-compression when arranged inside the capsule.
- Coffee maker machines specially made to prepare American coffee and characterized by a very simple operation are commercially available.
- In fact, these machines comprise a water tank, a pump that sends the heated water inside a small container provided with a paper filter containing the coffee. The hot water submerges the coffee and, passing through the paper filter, falls by gravity into the underlying carafe suited to keep the drink hot for a long time as it is heated by a suitable electrical resistance element.
- In addition to the traditional American coffee makers wherein the cup-shaped filter is filled manually by the user, capsules which have an outer casing wherein a paper filter partly filled with un-pressed coffee is inserted have recently appeared on the market.
- By means of specialized percolator machines the lid and the bottom in plastic material are perforated so as to create a flow of hot water allowing an infusion of the coffee powder.
- However, the capsules currently on the market do not work reliably. In fact normally only providing a filter on the bottom, the incoming hot water is induced to flow along substantially vertical preferential fluid threads and therefore does not affect the entire mass of the powdered product contained inside the capsule.
- Therefore, the main purpose of the present invention is to provide an interchangeable infusion capsule wherein the infusion water path within the capsule itself is as extended and tortuous as possible to delay the infusion time and to affect a greater quantity of product as possible.
- Further object of the present invention is to provide an innovative method for obtaining said infusion.
- According to the present invention, therefore, a interchangeable capsule is obtained, as claimed in claim 1 or in any of the claims depending directly or indirectly on claim 1.
- Always in accordance to the principles of the present invention, is provided an innovative method for obtaining an infusion of a powdered product, as claimed in claim 11 or in any of the claims depending directly or indirectly on claim 11.
- For a better understanding of the invention in the following is described a purely illustrative and not limitative embodiment, with the aid of the accompanying drawings, wherein:
-
FIG. 1 illustrates an exploded view of a capsule according to the present invention; -
FIG. 2 is a longitudinal section of the capsule, in use, according to the present invention; -
FIG. 3 is a plan view of a variant in a first detail; and, -
FIG. 4 illustrates the section IV-IV ofFIG. 3 . - In the attached figures a preferred embodiment of an
interchangeable capsule 90 according to the teachings of the present invention has been shown. - The
interchangeable capsule 90 is suited to contain inside, as will be better explained later, a certain quantity of a powdered product (for example coffee) for obtaining an infusion, in particular of “American coffee” according to the definition given above. - The
interchangeable capsule 90 comprises a cup-shaped body 101, which has a longitudinal axis (Y), aninner cavity 91, anupper opening 92 and alower opening 93 opposite to each other. Thecapsule 90 also comprises alid 102, which closes saidupper opening 92, and abasket 94, which is arranged inside the cup-shaped body 101 and is suited to house the powdered product. - The
basket 94 is made substantially of water-permeable material and acts as a filtering means for the infusion created by the water and by the powdered product, as will be further and better explained. Preferably, thebasket 94 is made of non-woven fabric; alternatively, thebasket 94 is made of plastic material for food use and has a plurality of micro slits for filtering the infusion. Preferably, thebasket 94 is made of a deformable material. - The
basket 94 is fixed inside thecapsule 90 by means of the interaction between the cup-shaped body 101 and thelid 102 and rests on thebottom 101A of the cup-shaped body 101, as will be better explained later. Thecapsule 90 comprises, finally, abase 100 defined by a disc of rigid material with a circular profile. Preferably, thebottom cover 100 is made of plastic material suitable for food use. Thebottom cover 100 is inserted in thebasket 92 so as to extend transversely to the longitudinal axis (Y) and is interposed between theupper opening 92 and thelower opening 93. - The cup-
shaped body 101 comprises, in turn, abottom 101A obtained advantageously, but not necessarily, in one piece with alateral wall 101B. - Note that through the
bottom 101A an axis (X) passes, that lies substantially on a plane (n) which defines a substantially horizontal direction. - Furthermore, in the present context any “substantially horizontal” body element or device is a body element or device that lies substantially on the plane (n). It must obviously be considered as “substantially horizontal” also body elements or devices which lie substantially on any plane parallel to the plane (n).
- As shown in the figures, the longitudinal axis (Y) is a central vertical axis of symmetry perpendicular to said axis (X).
- So, in the present context any body element or device “substantially vertical” is a body element or device that substantially extends according to the direction defined by the axis (Y).
- The
lateral wall 101B has the usual substantially frusto-conical countersunk shape along the axis (Y). - The cup-
shaped body 101 has anupper end 103 and comprises acontact edge 104 in the shape of a circular crown which protrudes radially outside thelateral wall 101B to ensure that the entireinterchangeable capsule 90 can be housed in an appropriate receptacle obtained in a percolator machine (not shown). The supportingedge 104 also has acircular recess 104A obtained along the entire inner circular perimeter of thecontact edge 104 itself. Therecess 104A is facing inside thecavity 91. - The cup-
shaped body 101 comprises, furthermore, aring 111 coaxial with the axis (Y) and which axially protrudes from thebottom 101A outside of the cup-shaped body 101 itself. Thering 111 is suited to form a watertight sealing area in contact with a contact base of thecapsule 90. - Preferably, but not necessarily, the
bottom 101A, thelateral wall 101B, thecontact edge 104 and thering 111 are made in one piece with a suitable, known type plastic material for food use. - The cup-
shaped body 101 also comprises a plurality ofribs 105 that protrude longitudinally to thelateral wall 101B and within thecavity 91. Theribs 105 are evenly distributed around the axis (Y). Twoadjacent ribs 105 of the cup-shaped body 101 define arespective infusion channel 106. Eachrib 105 extends from thebottom 101A up to about 80% of the overall longitudinal extension of thecavity 91. - The cup-
shaped body 101 comprises, furthermore, a plurality ofsupport elements 107, which protrude from thebottom 101A inside thecavity 91. As shown in the figures, thelower opening 93 is concentric with the axis (Y) and thesupport elements 107 are evenly distributed around saidlower opening 93. - The
support elements 107 form a labyrinth path. In particular, thesupport elements 107 are divided into radial walls 107A and curved walls 107B. The radial walls 107A are interposed between the curved walls 107B and the opening 93. As shown inFIG. 2 , the curved walls 107B are evenly distributed around the longitudinal axis (Y) and are formed as portions of a cylindrical body. Preferably the walls 107B are four and each curved wall 107B has a central angle of about 80°. The radial walls 107A are evenly distributed around the longitudinal axis (Y).

-
- the
capsule 90 of the invention has preferably, but not necessarily, ahole 108 from which the first entry of the hot water from a jet of the machine takes place; the hot water is thus evenly distributed in the mass of powdered product contained inside thebasket 94; this feature allows to control in a uniform and constant way the distribution of water in thecapsule 90 itself; - the bottom of the
basket 94 is closed to prevent preferential vertical outflows of water in the infusion step, as instead happens for the other known capsules on the market having a filter on the bottom or a single opening created due to a puncture of the bottom itself; - the filtering area of the infusion is substantially vertical through the
lateral walls 95 of thebasket 94 so as to have a larger filtration area with respect to the capsules providing a coffee filter arranged only on the bottom; furthermore, this vertical filtering creates a turbulence effect improving the exploitation of the product to be infused; - with the
capsule 90 it is possible, in the industrialization step, to perform central dosing thus simplifying the implementation of the machinery responsible for the packaging of the same; - the
ribs 105 maintain thelateral wall 95 of thebasket 94 spaced from thelateral wall 101B of the cup-shapedbody - the
ribs 105 together with thelateral wall 95 of the basket delimit a plurality ofpreferential channels 106 which allow the outflow of the infusion liquid and allow particularly advantageous timing and constant dispensing; in particular, it is to be noted that the shape and the size of eachpreferential channel 106 is definable by the suitable dimensioning of theribs 105, so as to obtain the best possible quality of fluid infusion given by obtaining both the optimal pressure and speed of the outflow; - the
protrusions 110 increase the filtration area being equal the total radial dimensions of thecapsule 90; and - the particular distribution of the
support elements 107 on the bottom 101A allows to create a tortuous path of the filtrated infusion liquid thus improving the quality, in particular, allowing a greater extractive capacity of the infusion; moreover, the path of thesupport elements 107 affects the outflow of the filtrated infusion liquid along saidpreferential channels 106; - the possibility to easily disassemble the
lid 102 and thebasket 94 from the cup-shapedbody capsule 90 being able to differentiate the components, one with respect to the other, according to the type of waste (plastic-organic); moreover, in this way it is also possible to reuse multiple times the cup-shapedbody lid 102 only substituting the basket 94 (reduction of waste).
