La presente invention concerne egalement une machine a cafe comprenant un tel The present invention also relates to a coffee machine comprising such a
porte-filtre a cafe.coffee filter holder.
Des portes-filtre a cafe vent connus dans l'etat de la technique. A titre d'exemple, la demande internationale PCT N WO 97/39668 decrit un portefiltre pour preparer une tasse de cafe ayant une couche de mousse. L'assemblage comprend un porte-filtre dont le fond comporte au moins un ouverture d'ecoulement et un filtre a cafe. L'assemblage connu est caracterise en particulier par le fait qu'il comprend, d'une part, un filtre en papier au travers duquel le cafe s'ecoule hors du filtre et une plaque de separation ayant au moins une ouverture d'ecoulement, Coffee filter holders are known in the state of the art. By way of example, international application PCT N WO 97/39668 describes a portfolio for preparing a cup of coffee having a layer of foam. The assembly comprises a filter holder, the bottom of which comprises at least one flow opening and a coffee filter. The known assembly is characterized in particular by the fact that it comprises, on the one hand, a paper filter through which the coffee flows out of the filter and a separation plate having at least one flow opening,
ladite plaque etant situee entre le cOte inferieur du filtre et le fond du porte-filtre. said plate being located between the lower side of the filter and the bottom of the filter holder.
Cette machine fonctionne de la maniere suivante. L'eau chaude est amenee dans le porte-filtre et mouille le cafe moulu se trouvant dans le filtre. Comme le filtre a cafe comprend un filtre en papier, l'eau chaude va s'ecouler a travers le filtre a cafe sans monter en pression dans le filtre a cafe. Par la plaque de separation, une pression elevee est creee dans l'espace compris entre la plaque de separation et le filtre a cafe. L'extrait de cafe est force au travers des ouvertures de la plaque de telle fa$on que des bulles vent formees dans l'espace situe de l'autre cote de la This machine works as follows. Hot water is brought into the filter holder and wets the ground coffee in the filter. As the coffee filter includes a paper filter, hot water will flow through the coffee filter without increasing pressure in the coffee filter. Through the separation plate, high pressure is created in the space between the separation plate and the coffee filter. The coffee extract is forced through the plate openings so that bubbles are formed in the space on the other side of the
plaque de separation par rapport au filtre a cafe. separation plate from the coffee filter.
La demande de brevet europeen N O 459 323 decrit un porte-filtre pour machine a cafe du type "espresso". Ce porte-filtre comprend une coupelle de reception d'un filtre a cafe dont le fond est perfore, une chambre collectrice dtinfusion comportant un couloir dont le debouche communique avec un entonnoir de distribution. En outre, le porte-filtre decrit comprend un dispositif de confection de mousse constitue d'une lame flexible disposee transversalement au debouche, dont une extremite est ancree dans la chambre et l'autre extremite est appliquee PO/1. CS17. 12FR. 4/apt European patent application N 459 323 describes a filter holder for an espresso machine. This filter holder comprises a cup for receiving a coffee filter, the bottom of which is perforated, a collecting chamber for infusion comprising a corridor whose outlet communicates with a dispensing funnel. In addition, the filter holder described comprises a device for making foam consisting of a flexible blade disposed transversely at the outlet, one end of which is anchored in the chamber and the other end of which is applied PO / 1.

Le brevet europeen N O 749 283 finalement decrit une capsule de filtre a cafe pour machine du type "expresso". Dans cette capsule, on a forme une chambre de pression entre deux plaques, l'une des plaques etant constituee par la plaque filtre de la capsule. La pression est creee par la presence de trous dont la petite dimension s'oppose a l'ecoulement de l'extrait de cafe, formant ainsi cette chambre with a certain force against said opening so as to obtain an infusion jet only when the pressure in the chamber is greater than the force of application of the free end of the blade against the opening, as well as a partition arranged around the blade and extending towards the teas so that the infusion jet comes to spray on the partition, forming foam. European patent N 0 749 283 finally describes a coffee filter capsule for "espresso" type machines. In this capsule, a pressure chamber is formed between two plates, one of the plates being constituted by the filter plate of the capsule. The pressure is created by the presence of holes whose small dimension opposes the flow of the coffee extract, thus forming this chamber

la forme d'un filtre reutilisable, generalement en metal, comme dans les machines plus couramment destinees a un usage professionnel, ou d'une capsule jetable, comme celles destinees plus couramment a un usage domestique. Ce filtre 2 comporte en general, et de maniere connue, une partie formant recipient 3 dans laquelle le cafe moulu est introduit et un fond 4 perce formant le filtre proprement dit, eventuellement recouvert par une membrane de tissu ou de papier, retenant le the form of a reusable filter, generally made of metal, as in machines more commonly intended for professional use, or a disposable capsule, such as those more commonly intended for domestic use. This filter 2 generally comprises, and in a known manner, a container part 3 into which the ground coffee is introduced and a bottom 4 pierces forming the filter proper, possibly covered by a membrane of fabric or paper, retaining the
mare de cafe, mais laissant passer l'extrait de cafe liquide. pool of coffee, but letting the liquid coffee extract pass.
En dessous du filtre 2, on trouve une plaque de fermeture S deformable qui est pressee contre le fond perce 4 du filtre 2 par l'intermediaire d'une portee 6 taillee Below the filter 2, there is a deformable closing plate S which is pressed against the pierced bottom 4 of the filter 2 by means of a cut surface 6

La plaque deformable est decrite plus en detail en reference aux figures 2 et 3. The deformable plate is described in more detail with reference to Figures 2 and 3.
Dans la figure 2, un porte-filtre est represente en coupe, vu de dessus mais sans filtre. Le porte-filtre 1 a une forme generale cylindrique dans loquel la plaque 5 est posee en appui sur la portee 6 qui, de preference, s'etend sur tout le diametre In Figure 2, a filter holder is shown in section, seen from above but without filter. The filter holder 1 has a generally cylindrical shape in which the plate 5 is placed in abutment on the bearing surface 6 which, preferably, extends over the entire diameter

La plaque 5 (figure 2 et 3) a la forme generale d'un disque et comporte, de preference, trots projections laterales 11, 12 et 13 qui s'etendent dans le plan de la plaque 5. Ces projections 11, 12 et 13 vent de preference formees en etant reparties de facon equidistante sur le pourtour de la plaque 5, par exemple tout les The plate 5 (FIGS. 2 and 3) has the general shape of a disc and preferably comprises trots lateral projections 11, 12 and 13 which extend in the plane of the plate 5. These projections 11, 12 and 13 wind preferably formed by being distributed equidistantly around the periphery of the plate 5, for example all
, en considerant le milieu de chaque projection 11, 12 ou 13. , considering the middle of each projection 11, 12 or 13.
Le fonctionnement du systeme selon ['invention est le suivant: de maniere classique, l'eau chaude est introduite sous pression au moyen d'une pompe de la machine a cafe dans le filtre et mouille la mouture de cafe. La pression de liquide obtenue dans le porte-filtre est de l'ordre de 10 a 15 bar. Le fond 4 du filtre 2 etant perce, la pression a l'interieur du filtre 2 s'applique directement sur la plaque 5, PO/I. CS17. 12FR. 4/apt The operation of the system according to the invention is as follows: conventionally, hot water is introduced under pressure by means of a pump of the coffee machine into the filter and wets the ground coffee. The liquid pressure obtained in the filter holder is of the order of 10 to 15 bar. The bottom 4 of the filter 2 being pierced, the pressure inside the filter 2 is applied directly to the plate 5, PO / I. CS17. 12GB. 4 / Apartment

celle-ci etant plaquee contre le fond 4 du filtre 2 par la portee 6 sur laquelle this being pressed against the bottom 4 of the filter 2 by the surface 6 on which
s'appuient les projections 11, 12 et 13 de la plaque 5. are based on the projections 11, 12 and 13 of the plate 5.
Lorsque la pression du liquide dans le filtre 2 est suffisante, la plaque 5 se deforme de maniere elastique vers le teas du porte-filtre 1, et le cafe s'ecoule par les zones 14, 15 et 16 qui se situent entre les projections 11, 12 et 13. De preference, la pression de fonctionnement du systeme est alors de ltordre de 13 bar environ. Cette deformation permet alors l'ecoulement du cafe entre la plaque 5 et le fond 4 du filtre 2, puis dans les canaux 7, 8 et l'ecoulement 9 pour finir dans un recipient When the pressure of the liquid in the filter 2 is sufficient, the plate 5 deforms resiliently towards the teas of the filter holder 1, and the coffee flows through the zones 14, 15 and 16 which are located between the projections 11 , 12 and 13. Preferably, the operating pressure of the system is then around 13 bar. This deformation then allows the flow of coffee between the plate 5 and the bottom 4 of the filter 2, then in the channels 7, 8 and the flow 9 to finish in a container.
(non represente), comme une tasse.(not shown), like a cup.
Le principe de ['invention effectue done au moins un laminage du cafe en sortie du filtre par ecrasement des molecules de graisse contenues dans le cafe, ce qui a pour consequence une production amelioree de mousse sur l'extrait de cafe The principle of the invention therefore performs at least one rolling of the coffee at the outlet of the filter by crushing the fat molecules contained in the coffee, which results in an improved production of foam on the coffee extract.
recueilli par les canaux 7, 8 et l'ecoulement 9. collected by channels 7, 8 and flow 9.
Conkairement aux systemes connus, le systeme selon ['invention utilise un principe reversible de sorte qu'une pression minimale doit etre maintenue dans le filtre 2 pour que le cafe puisse s'ecouler. Des que la pression diminue, la plaque 5 Similar to the known systems, the system according to the invention uses a reversible principle so that a minimum pressure must be maintained in the filter 2 so that the coffee can flow. As soon as the pressure drops, plate 5
se redresse contre le filtre 2 et l'ecoulement de cafe cesse. stands up against filter 2 and the coffee flow stops.
De preference, la force de rappel de la plaque 5 est de l'ordre de 40 kilos. Bien Preferably, the return force of the plate 5 is of the order of 40 kilos. Well
entendu, cette valeur peut etre variee si necessaire. of course, this value can be varied if necessary.
La plaque 5 peut etre faite en toute matiere deformable selon le principe de ['invention et acceptable pour ce type d'applications. A titre d'exemple, on peut The plate 5 can be made of any deformable material according to the principle of the invention and acceptable for this type of application. For example, we can
utiliser une plaque de 1 mm d'epaisseur en anticorrodal. use a 1 mm thick anticorrodal plate.
