Description
TECHNICAL FIELD
[0001] The present invention relates to an interchangeable capsule
to prepare an infusion of a powdered product, for example coffee or
similar products.
[0002] The present invention also relates to a method for obtaining
an infusion of said powdered product.
[0003] In particular, the present invention is directed to prepare
the so-called "American coffee".
[0004] 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.
BACKGROUND ART
[0005] 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.
[0006] 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.
[0007] Coffee maker machines specially made to prepare American
coffee and characterized by a very simple operation are
commercially available.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
DISCLOSURE OF INVENTION
[0012] 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.
[0013] Further object of the present invention is to provide an
innovative method for obtaining said infusion.
[0014] 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.
[0015] 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.

BEST MODE FOR CARRYING OUT THE INVENTION
[0021] In the attached figures a preferred embodiment of an
interchangeable capsule 90 according to the teachings of the
present invention has been shown.
[0022] 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.
[0023] The interchangeable capsule 90 comprises a cup-shaped body
101, which has a longitudinal axis (Y), an inner cavity 91, an
upper opening 92 and a lower opening 93 opposite to each other. The
capsule 90 also comprises a lid 102, which closes said upper
opening 92, and a basket 94, which is arranged inside the
cup-shaped body 101 and is suited to house the powdered
product.
[0024] 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, the basket 94 is made of non-woven
fabric; alternatively, the basket 94 is made of plastic material
for food use and has a plurality of micro slits for filtering the
infusion. Preferably, the basket 94 is made of a deformable
material.
[0025] The basket 94 is fixed inside the capsule 90 by means of the
interaction between the cup-shaped body 101 and the lid 102 and
rests on the bottom 101A of the cup-shaped body 101, as will be
better explained later. The capsule 90 comprises, finally, a base
100 defined by a disc of rigid material with a circular profile.
Preferably, the bottom cover 100 is made of plastic material
suitable for food use. The bottom cover 100 is inserted in the
basket 92 so as to extend transversely to the longitudinal axis (Y)
and is interposed between the upper opening 92 and the lower
opening 93.
[0026] The cup-shaped body 101 comprises, in turn, a bottom 101A
obtained advantageously, but not necessarily, in one piece with a
lateral wall 101B.
[0027] Note that through the bottom 101A an axis (X) passes, that
lies substantially on a plane (n) which defines a substantially
horizontal direction.
[0028] 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).
[0029] As shown in the figures, the longitudinal axis (Y) is a
central vertical axis of symmetry perpendicular to said axis
(X).
[0030] 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).
[0031] The lateral wall 101B has the usual substantially
frusto-conical countersunk shape along the axis (Y).
[0032] The cup-shaped body 101 has an upper end 103 and comprises a
contact edge 104 in the shape of a circular crown which protrudes
radially outside the lateral wall 101B to ensure that the entire
interchangeable capsule 90 can be housed in an appropriate
receptacle obtained in a percolator machine (not shown). The
supporting edge 104 also has a circular recess 104A obtained along
the entire inner circular perimeter of the contact edge 104 itself.
The recess 104A is facing inside the cavity 91.
[0033] The cup-shaped body 101 comprises, furthermore, a ring 111
coaxial with the axis (Y) and which axially protrudes from the
bottom 101A outside of the cup-shaped body 101 itself. The ring 111
is suited to form a watertight sealing area in contact with a
contact base of the capsule 90.
[0034] Preferably, but not necessarily, the bottom 101A, the
lateral wall 101B, the contact edge 104 and the ring 111 are made
in one piece with a suitable, known type plastic material for food
use.
[0035] The cup-shaped body 101 also comprises a plurality of ribs
105 that protrude longitudinally to the lateral wall 101B and
within the cavity 91. The ribs 105 are evenly distributed around
the axis (Y). Two adjacent ribs 105 of the cup-shaped body 101
define a respective infusion channel 106. Each rib 105 extends from
the bottom 101A up to about 80% of the overall longitudinal
extension of the cavity 91.
[0036] The cup-shaped body 101 comprises, furthermore, a plurality
of support elements 107, which protrude from the bottom 101A inside
the cavity 91. As shown in the figures, the lower opening 93 is
concentric with the axis (Y) and the support elements 107 are
evenly distributed around said lower opening 93.
[0037] The support elements 107 form a labyrinth path. In
particular, the support 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 in FIG.
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.degree.. The radial walls 107A are
evenly distributed around the longitudinal axis (Y). Preferably the
radial walls 107A are fourteen.
[0038] As a result from what has just been described, each support
element 107 is spaced from another support element 107, so that on
the bottom of the cup-shaped body 101 a labyrinth path arranged
radially around the lower opening 93 is formed.
[0039] As illustrated in FIGS. 1 and 2, the basket 94 has the shape
of a cup-shaped body and comprises a lateral wall 95 and a bottom
96, which delimit an inner cavity 97 and an upper opening 98. The
basket 94 also comprises an edge 99 which projects radially
outwards from the lateral wall 95.
[0040] Finally, the lid 102 has a substantially circular shape in
plan and has a circular shaped central hole 108 for the passage of
water. Preferably, the lid 102 is made of known type plastic
material for food products. The lid 102 also comprises a filter 109
suited to close the hole 108. Preferably, the filter 109 is made of
non-woven fabric or, alternatively, is made of plastic material for
food use and is suited to be torn at the time of use. According to
a variant, not illustrated, the lid is made of a peelable film
material fixed in a known manner, for example welded, on the edge
104 of the cup-shaped body 101. According to a variant, not
illustrated, the lid is continuous and has no holes or filters.
[0041] As shown in the figures, the basket 94 is arranged within
the cup-shaped body 101 so that its bottom 96 is in contact with
the support elements 107 of the cup-shaped body 101 itself.
Preferably, the bottom 96 of the basket 94 is fixed in a known
manner, for example welded, on the support elements 107. The edge
99 of the basket 94 is supported on the recess 104A of the
cup-shaped body 101. Preferably, the edge 99 is welded in a known
way on the recess 104A.
[0042] The bottom cover 100 is inserted inside the cavity 97 of the
basket 94 and is arranged so as to be coaxial with the axis (Y).
Preferably, the bottom cover 100 is resting on the bottom 96 of the
basket 94. The bottom cover 100 is fixed to the bottom 96 of the
basket 94 by way of known methods (hence the bottom cover 100 is
fixed by means of the basket 94 also to the support elements 107);
for example, the bottom cover 100 is welded or glued to the bottom
of the basket 94.
[0043] According to a variant not illustrated, the bottom cover 100
is fixed to the bottom 96 of the basket 94 and to the outside of
the cavity 97. According to a further variant, not illustrated, the
basket 94 has a tubular shape and the bottom cover 100 is arranged
to close said tubular shape acting substantially as a bottom for
the basket 94. According to a further variant, not illustrated, the
bottom cover 100 is fixed, for example welded or glued, onto the
support elements 107.
[0044] The lid 102 is arranged within the upper opening 92 and is
coaxial with the longitudinal axis (Y). The lid 102 is supported
within the recess 104A and on the edge 99. Preferably, the lid 102
is welded to the edge 104 of the cup shaped body 101 at the recess
104A. Preferably, the lid 102 is mounted with interference inside
the edge 104 of the cup-shaped body 101 so as to hold the edge 99
of the basket 94 against the cup-shaped body 101 itself.
[0045] In FIGS. 3 and 4 an alternative 101' of the cup-shaped body
101 is illustrated, it is noted that in FIGS. 3 and 4 the elements
in common with the cup-shaped body 101 maintain the same numbering.
The cup-shaped body 101' comprises a plurality of support elements
107', which protrude from the bottom 96 inside the cup-shaped body
101 itself. The support elements 107' are arranged radially around
the axis (Y). The support elements 107' form a labyrinth path. The
support elements 107' are divided into bars of larger dimensions
107'A and into bars of smaller dimensions 107'B. Two adjacent bars
of smaller dimensions 107'B are interspersed with a bar of larger
dimensions 107'A.
[0046] The different arrangements of the support elements 107 or
107' on the bottom 96 of the cup-shaped body 101 or 101' are suited
to maximize the outflow and the quality of the infusion.
[0047] Preferably, the cup-shaped body 101, 101' and/or the basket
94 and/or the lid 102 are made of biodegradable material.
[0048] The operation of the present capsule 90 is the
following:
a) Pressurized or percolated hot water in the cup-shaped body 101,
101' is introduced through the hole 108 (possibly by breaking the
filter 109 if made of plastic material) according to the direction
and the way identified by the arrow (F1); b) the hot water after
passing the filter 109 immediately meets the powdered product
arranged in the cavity 97 of the basket 94 and the produced
infusion liquid/hot water begins to form; c) said infusion liquid
impacts the bottom 100 and is deflected horizontally and radially
according to the directions and the ways of the arrows (F2); d) the
infusion liquid is pushed through the lateral walls 95 and outside
the basket 94; e) the lateral wall 95 of the basket 94 is deformed
under the action of water pressure and against the ribs 105 of the
cup-shaped body 101 so to have a substantially curvilinear trend
with an alternation of longitudinal protrusions 110 protruding
inside the cavity 97, as will be better explained in the following;
f) the infusion liquid colliding with the lateral walls 101B of the
cup-shaped body 101, 101' is channeled within the channels 106
between the ribs 105; g) the infusion liquid flows along the
channels 106 towards the bottom 101A of the cup-shaped body 101,
101' in the direction (F3); and h) the infusion liquid flows
radially in the direction (F4) on the bottom 101A towards the
opening 93 and then is distributed to the outside of the capsule
90; flowing on the bottom 101A the infusion fluid passes through
the labyrinth path created by the support elements 107, 107'.
[0049] In particular, each protrusion 110 is made so as to be
arranged at least partially around a respective rib 105.
[0050] Preferably, each protrusion 110 is tapered in the vicinity
of both ends. In particular, each protrusion 110 has a
substantially trapezoidal cross-section the size of which varies
along the axis (Y). Preferably each protrusion has a radial
extension along the lateral wall 95 in correspondence of the lower
longitudinal ends and increased in correspondence to a central
area. Preferably the trapezoidal profiles of two adjacent
protrusions 110 are in contact with each other in the vicinity of a
substantially central area. Each protrusion 110 is suited to wrap,
at least partially, a respective rib 105, as will be better
explained in the following.
[0051] After the delivery of the infusion the cup-shaped body 101,
101' can be tightened below the edge 104 so as to cause a plastic
deformation in the cup-shaped body 101, 101' itself, and to allow
to extract the lid 102. In this way it is possible to clean up (for
example by emptying and rinsing) the basket 94 and separate the
plastic material from the organic material so as to facilitate the
recycling and separate collection of all the components of the
capsule 90.
[0052] From the above description, the bottom cover 100 is
transverse to the direction F1 of the liquid inserted in the basket
94 so as to divert the direction horizontally. The basket 94
basically acts as a filtering means wherein the lateral wall 95 is
suited to filter the infusion created by the mixing of water and
powdered product.
[0053] The present invention also relates to a method for the
production of a beverage infusion in particular of American coffee;
the method is characterized by the following steps:
(f1) centrally and vertically injecting a given amount of hot water
into the basket 94; (f2) causing at least part of the hot water to
be deflected in a substantially horizontal direction by the
deflector device 100; (f3) deforming the lateral wall 95 of the
basket 94 by means of the interaction of the hot water and of the
spacer elements, such as the ribs 105; (f4) filtering the infusion
in said substantially horizontal direction causing it to pass
through substantially vertical filtering means 95; 110 of the
basket 94 so as to convey said filtered infusion in preferential
channels 106 created between the cup-shaped body 90 and the basket
94; (f5) converging the filtered infusion along said preferential
channels 106 towards the bottom 101A of the cup shaped body 101;
101'; and (f6) mixing the filtered infusion by means of the support
elements 107; 107' before the outflow of the filtered infusion
itself from the capsule 90 through the opening 93 on the bottom
101A of said cup-shaped body 101; 101'.
[0054] The advantages of the capsule object of the present
invention are the following: [0055] the capsule 90 of the invention
has preferably, but not necessarily, a hole 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 the basket 94; this feature allows to
control in a uniform and constant way the distribution of water in
the capsule 90 itself; [0056] 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; [0057] the filtering area of the
infusion is substantially vertical through the lateral walls 95 of
the basket 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;
[0058] 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; [0059]
the ribs 105 maintain the lateral wall 95 of the basket 94 spaced
from the lateral wall 101B of the cup-shaped body 101, 101'
preventing the two to adhere (in this case the infusion liquid
would not be able to flow out in the direction (F3) outside the
basket 94); [0060] the ribs 105 together with the lateral wall 95
of the basket delimit a plurality of preferential 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 each
preferential channel 106 is definable by the suitable dimensioning
of the ribs 105, so as to obtain the best possible quality of fluid
infusion given by obtaining both the optimal pressure and speed of
the outflow; [0061] the protrusions 110 increase the filtration
area being equal the total radial dimensions of the capsule 90; and
[0062] 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 the support elements 107 affects the outflow of the filtrated
infusion liquid along said preferential channels 106; [0063] the
possibility to easily disassemble the lid 102 and the basket 94
from the cup-shaped body 101, 101' enables the total recyclability
of all the components of the 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-shaped body 101, 101' and
the lid 102 only substituting the basket 94 (reduction of
waste).
