Full Text "Device for the production of beverages by infusion"
The present invention relates to a device for the
production of beverages by infusion from a product
contained in a tablet.
It finds particular use in the field of the production
of coffee from ground coffee prepackaged in tablets.
Such tablets already exist and are generally
constituted by an assembly of two sheets of filter paper
providing an intermediate space for packaging the ground
coffee.
Various machines for extracting hot beverages from
coffee grounds are known.
Particularly, WO-A-00/38558 discloses an extraction
chamber for an automatic machine for the preparation of hot
beverages, in which the extraction chamber is provided to
receive tablets or pellets preloaded with ground coffee.
The chamber is constituted of two parts, each movable
in a horizontal plane so as to be able to move toward or
away from each other.


Moreover, according to this document, the two portions
are also movable in an oscillating manner.
A machine thus constituted gives general satisfaction
but requires the drive of the two constituent parts of the
chamber.
It is thus necessary to provide sufficiently powerful
motorization and a system of power transmission that is
relatively complicated, requiring the synchronization of
the movements.
There is moreover known, from FR-A-2. 745. 995 an
apparatus for the production of beverages in which the
infusion chamber is constituted by two half recesses, one
carried by one surface of the body of the apparatus, the
other fixed to a surface of the heater, these two surfaces
facing each other.
The infusion chamber is formed when the two half
recesses are joined.
Disassembly of the chamber takes place by a
translatory movement of one of the recesses.
The apparatus thus provided requires the association
of different abutment means ensuring the retention of the
tablet at the time of supply, then during its entry into
the infusion chamber.
A mobility of the abutment means is equally necessary
to ensure the ejection of the used tablets.
The prior art disclosed by this reference requires the
provision of separate abutment and ejection means for the
tablets.
The present invention permits overcoming these
drawbacks.
It provides for this purpose an improved device for
the production of beverages.




A first advantage of the invention is to permit
carrying out the opening and closing phases of the infusion
chamber as well as the performance of the phases of
introduction and injection of the tablets, by means of a
lesser number of movements and in particular by the
combined movement of rotation and translation of only one
of the constituent parts of the chamber.
It has overcome the prejudice according to which the
placing into abutment of the tablet and the opening and
closing of the chamber require mobility of a plurality of
pieces: two half chambers or additional abutments.
Another advantage of the invention is requiring in a
preferred embodiment only a single drive means for the
movement of rotation to a movement of translation, thereby
ensuring with certainty and least cost the synchronization.
According to a preferred modification, the invention
is such that it can be used and actuated by a user by the
force of a lever.
Other objects and advantages will become apparent from
the description which follows of a preferred embodiment of
the invention which is however not limiting.
The present invention relates to a device for the
production of beverages by infusion of a product contained
in a tablet, comprising an infusion chamber adapted to
receive a tablet and comprising two portions arranged to be
brought together or spaced apart to close or open the
infusion chamber, characterized by the fact that one of the
portions has a movement in rotation adapted to place the
tablet in abutment in said portion, the portion movable in
rotation has a movement in translation to open or close the
infusion chamber, and in that it comprises common drive
means for movement in translation and movement in rotation

of the movable portion, said drive means comprising a
rotatable drive shaft coupled to the movable portion by at
least one rod mounted pivotally between said drive shaft
and said movable portion.
According to preferred modifications, the device is
such that:
it comprises a translatory member secured to the
movable portion in its translation movement and relative to
which it is movable in rotation.
it has guide means in translation for the
translatory member.
- the shaft is actuated in rotation by a lever.
it comprises means for holding closed the two
portions of the infusion chamber.
- it comprises guide means for the tablet.
- the guide means comprise a slide way with at least
one groove adapted to receive the periphery of a tablet.
- the guide means are mounted in translation to follow
the movement toward or away from each other of the
portions.
- it comprises a heater located on the side of the
portion fixed in rotation.
The accompanying drawings are given by way of example
and are not limiting of the invention. They show only an
embodiment of the invention and will permit easy
comprehension of it.
Figure 1 is a general perspective view of the device
of the invention.
Figure 2 is a top plan view.
Figures 3 and 4 are respectively side and longitudinal
cross-sectional views of the device of the invention in the
position for supplying tablets.

Figures 5 and 6 are respectively side and cross-
sectional views of the device of the invention in a
position for receiving tablets in the infusion chamber.
Figures 7 and 8 are respectively side and longitudinal
cross-sectional views of the device of the invention in the
extraction position.
Referring to the drawings, and particularly to Figures
1 and 2, the device according to the invention has in a
conventional manner a heater 9 adapted to supply the
infusion chamber 1 with hot water for the extraction of the
material contained in the tablet and particularly of the
ground coffee.
As shown in Figure 4, a water circuit 10 is present
through the device with a portion 11 for admission of hot
water into the infusion chamber 1 and an outlet portion 12
opening into a trough pouring the beverage into a funnel to
the receptacle of the user.
The tablets used for the operation of the present
invention could be of known type available on the market.
Preferably, but in a non-limiting manner, there could
be used tablets 2 comprising a substantially flat and rigid
periphery ensuring maintaining the shape of the tablet.
The infusion chamber 1 is constituted by two portions
3, 4 adapted to be brought together to close the chamber 1
as shown in Figures 7 and 8 or to be spaced apart to open
it as shown in Figures 3 to 6.
Preferably, and in the description that follows, it is
the portion 3 which will move in translation to move toward
or away from the other portion 4.
Moreover, the portion 3 is given a movement of
rotation over a limited path to pass between various
positions during operation.

Preferably, there is used a same drive means to ensure
the translation and the rotation of the movable portion 3.
There is shown by way of example in Figure 4, the
position of the axis 8 of rotation of the movable portion 3
and the axis 7 of its translation.
In what follows of the description and with reference
to the drawings, the example of the extraction machine is
in a horizontal position (in which the tablet is positioned
substantially vertically and receives hot water along a
substantially horizontal circuit).
However, other orientations are possible without
departing from the scope of the invention.
The single drive means is constituted by a drive shaft
13 with a horizontal axis of rotation and adapted to cause
movements of the movable portion 3.
To do this, the shaft 13 co-acts with at least one rod
14a, 14b but preferably two rods.
As is shown for example in Figure 4, the rod 14a, 14b
is mounted on a connection pivot 16, 17 on the one hand on
the shaft 13 and on the other hand on the rear end of the
movable portion 3.
A translatory member 21 is also provided to follow
securely the movement of translation of the movable portion
3 and to ensure the pivotal articulation about the axis 8
of said movable portion 3.
The translation of the member 21 is moreover guided by
guide means which could be constituted by two lateral
guides 30a, 30b as shown in Figure 2.
According to a first possibility, the shaft 13 is
driven in rotation by a motor.

According to a second possibility, shown in the
figures, the driving in rotation is carried out by means of
a lever 15 that can be actuated by the user.
In this case, the movable portion 3 is inclined
downwardly to provide an abutment surface 6 in its other
portion to co-act with the external roller surface of the
tablet 2.
The surface 6 thus constitutes an abutment in the
supply phase of the tablet 2.
To improve the sealing of the infusion chamber 1 in
the closed position, it is preferable to add to the closure
pressure provided by the user by means of the lever 16, an
additional pressure.
In this case, a closure gripping means for the two
portions 3, 4 of the infusion chamber 1 can be constituted
as a supplement.
By way of preferred example, there will be used
closure means in the form of a hydraulic jack with a
membrane whose movable membrane is adapted to give rise to
a slight movement of portion 4 of the infusion chamber.
Any other gripping means is also envisageable.
Preferably, the device able comprises guide means for
the tablet 2 during its movement during operating phases.
In this case, there could be provided guide means in
the form of a slide way 25 constituted by two grooves 26
adapted to encase the periphery of the tablet 2.
The periphery of said tablet 2 can be inserted in each
of the grooves 26 thus provided.
The guide means are preferably mounted for translation
to follow the movement toward and away from each other of
the two portions.

In this case, these means have a movement coupled with
that of the translatory member 21 by means of pushers 31
shown particularly in Figure 3.
The pusher 31 comprises a portion with a gap 32
adapted to constitute two bearing portions of the pusher 31
on one corresponding surface of the guide means.
In this way, the movement of the guide means follows
that of the translatory member 21 in the course of the
operating phases.
Moreover, the vacuum drawn between the two bearing
surfaces formed by the gap 32 ensures a retardation of the
movement of the guide means adapted to ensure first of all
an advance of the movable portion 3 alone, then a joint
advance of the guide means and the movable portion 3 toward
the fixed portion 4.
The pusher system thus constituted can be provided in
a guided fashion about two lateral guides 30a, 30b ensuring
the guidance and translation of the movable elements and
the coherence of the constituent pieces of the device.
The phases of operation of the present device will be
more particularly shown in Figures 3 to 8.
Figures 3 and 4 show a first position of operation of
the device in which the tablet 2 is in abutment position on
the upper wall of the movable portion 3.
The lever 15 is itself in a predetermined angular
position, vertical in this case.
An actuation of the lever 15 in the trigonometries
direction permits arriving at the position shown in Figures
5 and 6 in which the tablet 2 is received in the movable
portion 3.
Between these two phases of movement, the drive shaft
13 has caused the bearing of the rod 14a against the rear

portion of the movable portion 3 and has particularly
caused a rotation of the movable portion in the clockwise
direction.
Continuing the rotation of the lever 15, the shaft 13
gives rise to a supplemental pressure on the movable
portion 3 by means of rods 14a, 14b, this supplemental
pressure tending to translate the movable portion 3 and to
cause its closing to constitute the extraction chamber 1.
There can be provided abutment services particularly
on the translatory member 21 to limit the angular mobility
of the movable portion 3.
Thus, in the position shown in Figures 7 and 8, the
movable portion 3 closes the extraction chamber 1.
When the infusion chamber is closed, hot water is
injected into the infusion chamber.
The beverage is recovered in the trough.
When brewing is completed, a reverse movement of the
shaft 13 causes the retraction of the movable portion 3 and
its pivoting in the trigonometric direction.
The movable portion being out of the way, the tablet 2
can be freed and fall by gravity toward a recovery zone.
The movable portion 3 thus having pivoted downwardly,
ensures the formation again of the supply abutment surface
6 on the upper portion of the movable portion 3.
Figures 3, 5 and 7 show in side view the performance
of translatory movement of the guide means when the latter
is present.
In this case, there is seen the pusher 31 adapted to
cause the advance of the guide means 25 with the advance of
the movable portion 3.
The gap 32 present on the pusher 31 however ensures
retardation of the translation of the guide means 25.

The end of discharge of the tablet 2 takes place when
the movable portion 3 has retreated and while the guide
means 25 are still in position.
Once the tablet is evacuated, the guide means 25
undergo in turn a translation.
The retardation to the translation of the guide means
25 ensures the good dislodging of the tablet 2 before the
complete return to initial position of the device.
