Full Text Description
A capsule to be used to prepare an infused beverage
Technical field
The present invention relates to a capsule that can be used
to prepare an infused beverage.
In particular, the present invention relates to a single-
dose coffee capsule to be used in an espresso coffee machine in
which a flow of hot or boilling water forced through the capsule
positioned in a percolating chamber produces a hot milk or coffee
beverage, such as, for example, macchiato espresso coffee or
cappuccino, which the present specification expressly refers to
but without restricting the scope of the invention.
Background Art
Nowadays, a very popular way of preparing espresso coffee,
especially in the home, is to use single-dose "coffee pods", which
are extremely easy to use and readily available on the market.
Typically, in this context, a pod is a single measure of coffee or
other infusion product enclosed in a sealed filter paper container
or bag of substantially cylindrical shape designed to be placed in
a suitable holder forming part of the espresso coffee machine.
European patent EP 776166 El describes the mathod for making
a filter paper bag or pod where the infusion material, namely
coffee, is compressed, mixed with soluble additive material, such
as powdered milk or creamer or the like, and enclosed between two
layers of filter paper. The pod thus obtained can be used in an
espresso coffee machine to make a hot coffee and milk beverage,
espacially cappuccino,
The use of a pod of the type made of filter paper as
described in the aforementioned, patent, has considerable
disadvantages.
The hot water flowing through the filter paper pod dissolves

2
all the soluble additive material, namely the powdered milk,
present in the mixture, whilst the infusion material, namely the
coffee, tends to remain compacted. As a result, the beverage made
with pods of this kind often contains incorrect proportions of
milk to toffee. In other terms, the beverage made using the pods
described above, which are trade entirely of filter paper, contains
an excessively high concentration of milk, making it unpleasant to
the taste.
Another disadvantage of these pods made entirely of filter
paper is that the part of the mixture constituted by the soluble
additive material dissolves coupletely, thus partly emptying the
pod, causing it to become soft and spongy, and difficult to remove
from the holder of the coffee machine when an unused pod has to be
placed in the machine to make another cup of coffee.
The present invention has for an aim to provide a capsule
used to prepare an infused coffee and milk beverage that overcomes
the above mentioned disadvantages.
Disclosure of the invention
The present invention accordingly provides a capsule that
can be used to prepare an infixed beverage and that is
characterised in that it comprises a first container made of a
substantially flexible material and containing a powdered infusion
substance, and a second container made of a substantially rigid
material and containing a powdered soluble, substance.

Detailed description of the preferred embodiments of the invention
with reference to the accompanying drawings, the numeral 1
denotes a single-dose capeule for use in an espresso coffee
macnine to prepare a hot coffee and milk beverage, especially
cappuccino.
The espresso coffee machine, not illustrated because it is a
very well known type of machine, basically comprises a device for
producing a flow of hot or boiling water that is forced through
the capsule 1 once the latter has been placed in a holder in a
percolating chamber where the hot beverage is brewed.
The capsule 1 comprises a closed container or cartridge 2,
preferably in the shape of truncated cone made of a food safe
plastic material.
As illustrated in Figures 5 and 6, the bottom surface 3 of
the cartridge 2 has a central hole 4, preferably circular, covered
by a seal 5 of suitable material designed to be opened or pierced
by a hollow needle A forming part of the coffee machine, in an
alternative embodiment, the seal 5 forms, an integral part of the
bottom surface 3 of the cartridge 2, that is to say, it
constitutes a portion of the surfaces 3 that can be easily pierced.
The cartridge 2 holds a predetermined guantity at powdered
soluble "material NS comprising powered milk or creamer or the
like. The material MS may also comprise a predetermined quantity
of powdered sugar.
As illustrated in Figures 1 and from 3 to 5, the capsule 1
also comprises a container or pod 6 of filter paper or similar
filter material, containing a tablet of infusion material Ml,
namely coffee powder, and positioned at the top 7 of the cartridge
2.
More specifically, as shown in Figures 1, 2, 3 and 5, the

WO 2004/071899 PCT/IB2004/000396
4
outer annular edge 8 of the pod 6 rests on, and is fixed to, a
matching annular protuberance 9 of the cartridge 2, running round
the outer edge at the top 7 of the cartridge 2.
The edge 8 of the pod 6 ia fixed to the annular protuberance
9 of the cartridge 2 preferably by a gluing, heat-sealing or
similar process.
In a still more preferable solution, fixing is accomplished
by the currently known process of ultrasound sealing.
As illustrated, in Figures 2, 3 and 4, the capsule 1 is
advantageously covered and sealed by a sheet 10 of cover material,
such as, for example, aluminium foil or the like, which is applied
to the end of the protuberance 9 of the capsule 1 cartridge 2, for
example by gluing, heat sealing or ultrasound sealing, in such a
way aa to cover the top 11 of the pod 6, thus keeping in the aroma
of the coffee it contains.
The cover 10 is designed to be removed just before the
capsule l is placed by the user in the appropriate holder in the
coffee machine. The user can then start preparing the cappuccino
by pressing the coffee machine start button which causes a
relative movement between the needle A and the capsule 1 such that
the needle A pierces the seal 5 and penetrates the hole in the
capsule 1.
The flow of hot water produced by the machine passes first
through the pod 6, creating a flow of infused coffee Ml which
falls onto and wets the soluble creamer MS inside the cartridge 2
and from there flows through the hollow interior of the needle h
to produce cappuceino that fills an undarlying glass or cup (not
illustrated).
Thus, a delectable cappuccino with an optimum proportion of
milk to coffee, can be prepared every time.
Once used, the capsule 1 can be removed very easily from the
machine, thanks, especially to the closed, rigid structure of the
cartridge 2, Further, when the capsule 1 is moved away from the
needle A, the seal 5 tends to re-close the hole 4, preventing
residual water or beverage from dripping out and dirtying the user
or the area around the machine.
Moreover, it should be stressed, that the capsule 1 disclosed

WO 2004/071899 PCT/IB2004/000396

herein can be safely handled and sold without any overwapping
thanks to the rigid structure of the cartridge 2 and to the cover
10 attached to the top of it and placed, only over the top face of
the pod 6, This means legs packaging material is required which in
turn means not only considerable savings in tetms of lower
production and selling costs but also a reduced impact on the
environment.
It will be understood that the capsule as described herein can
be modified and adapted in several ways without thereby departing
from the a cope of the inventive concept. Moreover, all the details
of the invention may be substituted by technically equivalent
elements.
