Object of the invention
[0001] The present invention relates to a capsule for infusing a beverage which is configured
for being able to be inserted in a machine prepared for injecting water into the capsule,
flooding an inner space of said capsule, in order to finally obtain the beverage formed
by at least two different mixtures: a first mixture comprising water with a food product
and a second mixture comprising water with a preferably liquid food product.
Background of the invention
[0002] At present, beverage preparation capsules are known in which, after mixing a liquid
with a food product such as teas and coffee, said liquid mixture is filtered inside
the capsule through a filtering surface.
[0003] Capsules for producing beverages are also known which comprise a filter with a filtering
surface in the interior space thereof, through which the liquid mixture passes before
being extracted out through a lower opening of the capsule.
[0004] In all cases, the capsules normally comprise a hollow body in the shape of a cup
with a mouth hermetically closed by means of a sheet-like cover, which is attached
to a perimeter edge demarcating the mouth of the hollow body.
[0005] The food product and the filter are located inside the hollow body, such that in
order to extract the beverage, water is injected into the hollow body with a cannula
for being mixed with the food product, whereby the liquid mixture generated inside
the capsule increases in pressure, passing through the filter and finally through
an outlet opening in order to finally obtain the required beverage.
[0006] In some capsules, the outlet opening to allow the exit of the beverage is generated
as a result of the controlled tearing of the sheet-like cover due to the increased
pressure of the liquid mixture inside the hollow body, such that in these cases, said
cover includes a weakening line to facilitate the controlled tearing thereof and therefore
the outlet of the beverage.
[0007] In all cases, between the inner surface of the hollow body and the cover there is
a single inner chamber in which at least the filter and the food product are housed.
Description of the invention
[0008] In order to achieve the objectives and avoid the drawbacks mentioned in the preceding
sections, the invention proposes a capsule for infusing a beverage comprising a hollow
body having a base and a side wall with a perimeter flange demarcating a mouth closed
by means of a sheet-like cover attached hermetically by means of sealing to the perimeter
flange of the hollow body.
[0009] The hollow body comprises at least a first chamber and a second chamber isolated
from one another, which are separated by a partitioning wall structure attached to
the inner surface of the hollow body; wherein the first chamber is configured for
housing a first food product and the second chamber is configured for housing a second
food product.
[0010] The partitioning wall structure includes an edge to which the sheet-like cover is
hermetically attached by means of sealing.
[0011] In one embodiment of the invention, the capsule further comprises a sheet-like filter
which is arranged inside the hollow body and in proximity to the sheet-like cover,
while at the same time said sheet-like filter is hermetically attached by means of
sealing to the perimeter flange of the hollow body. The sheet-like filter is also
hermetically attached by means of sealing to the edge of the partitioning wall structure.
[0012] In one embodiment of the invention, the partitioning wall structure is attached to
the base and to the side wall of the hollow body.
[0013] The edge of the partitioning wall structure is flush with the perimeter flange of
the hollow body, while at the same time the partitioning wall structure comprises
at least two dividers converging in a central region of the hollow body.
[0014] The first chamber of the hollow body is configured for housing the first food product
in the form of powder or particles such as, for example, coffee, whereas the second
chamber is configured for housing the second food product in liquid state; wherein
both products are housed inside their respective chambers without being in contact
with one another and obviously without mixing inside the capsule.
[0015] As long as the capsule is closed, these two products remain without contact with
one another due to the existence of the partitioning wall structure, preferably formed
by inner dividers which split the interior space of the hollow body of the capsule
into at least two partitions (first and second chambers); where they will, typically
and as a particular example of the invention, occupy 1/4 (second chamber) and 3/4
(first chamber) of the interior space of the hollow body.
[0016] Said inner dividers of the hollow body will therefore hermetically divide the interior
space of said hollow body into two or more regions, preventing the mixing of the food
products contained therein, and said inner dividers will have a height equal to the
height of the hollow body, being flush with the perimeter flange thereof, so that
the sheet-like cover of the capsule as a whole allows the complete separation of the
chambers created with said inner dividers.
[0017] When water is injected into the two chambers, the water wets and soaks the first
food product forming a first liquid mixture simultaneously with the formation of a
second mixture of water together with the second liquid food product, such that pressure
inside the hollow body of the capsule gradually increases due to the continuous injection
of water.
[0018] In this situation with the pressure inside the hollow body, cuts are made at a given
moment on the sheet-like cover allowing the exit through same of the combination of
the two described liquid mixtures which will flow out like a stream into a container
placed beforehand below the sheet-like cover. The sheet-like cover is part of the
capsule. Both liquid mixtures flow out separately.
[0019] As a preferred embodiment of the invention, the capsule comprises the partitioning
wall structure formed by two partitioning dividers which allow containing a powder
part (coffee) and a liquid part (cognac, etc., or any type of alcoholic beverage),
which are only mixed once the capsule is introduced into the machine which supplies
pressurized water through the injector, configuring a beverage that is a mixture of
both food products such as, for example, the beverage commonly known as coffee with
a shot of liquor.
[0020] The materials used for manufacturing the capsule of the invention are the same as
those used in other conventional capsules of the state of the art.
[0021] Next, to help better understand this specification and as an integral part thereof,
a series of figures is attached in which the object of the invention is depicted in
an illustrative and non-limiting manner.

Description of an exemplary embodiment of the invention
[0023] Considering the numbering used in the figures, the capsule for infusing a beverage
comprises a hollow body 1 in the shape of a cup having a base 1a and a side wall 1b
with a perimeter flange 2 demarcating a mouth closed by means of a sheet-like cover
3 hermetically attached by means of sealing to the perimeter flange 2.
[0024] In the embodiment shown in the figures, the hollow body 1 comprises a truncated cone
configuration, without ruling out other configurations.
[0025] Moreover, in one embodiment of the invention, the capsule includes a sheet-like filter
4, whereas in another embodiment of the invention, the capsule does not include said
sheet-like filter 4.
[0026] There is located inside the hollow body 1 the sheet-like filter 4 which is located
parallel and in proximity to the sheet-like cover 3, while at the same time said sheet-like
filter 4 is hermetically attached, also by means of sealing, to the perimeter flange
2 of the hollow body 1. The sheet-like filter 4 is usually in contact with an inner
face of the sheet-like cover 3.
[0027] The hollow body 1 includes at least a first chamber 5 and a second chamber 6 separated
by a partitioning wall structure 7 attached to the base 1a and to the side wall 1b
of the hollow body 1, wherein said partitioning wall structure 7 comprises two dividers
converging in the diametric center of the truncated cone configuration of the hollow
body 1.
[0028] The partitioning wall structure 7 includes an edge 7a to which there are hermetically
attached by means of sealing both the sheet-like filter 4 and the sheet-like cover
3, such that in the embodiment which does not include the sheet-like filter 4, the
edge 7a of the partitioning wall 7 is attached directly to the sheet-like cover 3.
[0029] The two chambers 5 and 6 demarcate isolated and completely leak-tight interior spaces,
such that the first chamber 5 is configured for housing a first food product 9 in
the form of powder or particles such as, for example, coffee, and the second chamber
6 is configured for housing a second liquid food product 10 such as, for example,
cognac, to thereby enable directly obtaining a beverage made up of coffee and cognac,
which is commonly known as "coffee with a shot of liquor".
[0030] Both the first food product 9 and the second liquid food product 10 are in contact
with the inner surface of the hollow body 1 and also with the sheet-like filter 4
itself, or with the sheet-like cover 3 in the embodiment which does not include the
sheet-like filter 4.
[0031] When water is injected into the two chambers 5 and 6, the water wets and soaks the
first food product 9 forming a first liquid mixture simultaneously with the formation
of a second mixture of water together with the second liquid food product 10, such
that pressure inside the hollow body 1 of the capsule gradually increases due to the
continuous injection of water.
[0032] In this situation with the pressure inside the hollow body 1, cuts 12 are made at
a given moment on the sheet-like cover 3 allowing the exit through same of the combination
of the two described liquid mixtures which will flow out like a stream 11 into a container
placed beforehand below the sheet-like cover 3. Both liquid mixtures flow out separately.
[0033] The cuts 12 go through the sheet-like cover 3 communicating the interior space of
the hollow body 1 with the outside. Furthermore, it should be mentioned that the cuts
12 are made by means of sharp elements of a machine in which the capsule for infusing
a beverage is introduced.
[0034] In the embodiment which includes the sheet-like filter 4, both liquid mixtures go
through the sheet-like filter 4 separately until coming into contact with the inner
face of the sheet-like cover 3.
[0035] Water is injected into the first chamber 5 and the second chamber 6 by means of an
injector 13 having several branches 13a going through the base 1a of the hollow body
1; wherein the injector 13 has at least the same number of branches 13a as the number
of inner chambers for housing the different food products.
[0036] Figure 1a shows a hollow body 1 with the first chamber 5 and the second chamber 6,
whereas Figure 1b shows a hollow body 1 with the first chamber 5, the second chamber
6, and a third chamber 8.
