Un tel porte-cartouche est du type décrit dans la demande de brevet internationale PCT/CH91/00222 et peut être appliqué sur une machine à café espresso ou sur un autre appareil fournissant un liquide sous pression chaud ou froid.Such a cartridge holder is of the type described in international patent application PCT / CH91 / 00222 and can be applied to an espresso coffee machine or to another device supplying a liquid under hot or cold pressure.
Les porte-cartouches utilisés jusqu'à présent présentent une paroi filtre d'un prix de revient relativement élevé ou dont le fonctionnement ne permet pas d'obtenir la régularité des résultats souhaitable avec les différentes cartouches fabriquées en grandes séries.The cartridge holders used until now have a filter wall with a relatively high cost price or whose operation does not allow obtaining the regularity of the desirable results with the various cartridges produced in large series.
La présente invention vise à fournir un porte-cartouche du type susmentionné dont la fabrication notamment par moulage est plus simple et dont la forme permet un filtrage et un écoulement du produit liquide améliorés par rapport à certains porte-cartouches existants. A cet effet, le porte-cartouche selon l'invention est caractérisé en ce que les protubérances de la paroi filtre présentent, dans leur surface latérale, au moins une creusure de forme allongée ou une partie de forme allongée en retrait par rapport au prolongement des parties adjacentes de ladite surface latérale, cette creusure ou partie en retrait étant orientée du sommet vers la base de la protubérance.The present invention aims to provide a cartridge holder of the aforementioned type, the manufacture of which in particular by molding is simpler and the shape of which allows filtering and flow of the liquid product improved compared to certain existing cartridge holders. To this end, the cartridge holder according to the invention is characterized in that the protrusions of the filter wall have, in their lateral surface, at least one recess of elongated shape or a part of elongated shape set back relative to the extension of the adjacent parts of said lateral surface, this recess or recessed part being oriented from the top towards the base of the protuberance.
Les protubérances peuvent avoir une forme essentiellement pyramidale à base triangulaire, rectangulaire ou polygonale, et lesdites parties en retrait peuvent être situées, au moins en partie, à la place d'au moins une arête de la pyramide ou au voisinage d'une arête de la pyramide. Les creusures peuvent être des gorges disposées essentiellement dans le sens de la pente de la surface latérale des protubérances. Au moins l'un des bords longitudinaux des creusures ou parties en retrait forme de préférence, une arête avec la surface latérale de la protubérance.The protrusions may have an essentially pyramidal shape with a triangular, rectangular or polygonal base, and said recessed parts may be located, at least in part, in place of at least one edge of the pyramid or in the vicinity of an edge of the pyramid. The recesses can be grooves arranged essentially in the direction of the slope of the lateral surface of the protrusions. At least one of the longitudinal edges of the recesses or recessed parts preferably forms an edge with the lateral surface of the protuberance.
D'autres caractéristiques, buts et avantages de l'invention apparaîtront plus clairement à la lumière de la description suivante de différents exemples d'exécution illustrés par le dessin annexé, dans lequel:Other characteristics, objects and advantages of the invention will appear more clearly in the light of the following description of various exemplary embodiments illustrated by the appended drawing, in which:
La Fig. 1 est une vue en coupe simplifiée d'un porte-cartouche muni d'une cartouche neuve;Fig. 1 is a simplified sectional view of a cartridge holder provided with a new cartridge;
La Fig. 2 est une vue en perspective frontale d'une des protubérances d'un porte-cartouche selon l'invention;Fig. 2 is a front perspective view of one of the protrusions of a cartridge holder according to the invention;
La Fig. 3 est une vue en perspective d'une autre forme d'exécution d'une telle protubérance; etFig. 3 is a perspective view of another embodiment of such a protuberance; and
Les Figures 4 à 6 sont des vues de trois autres formes d'exécution d'une telle protubérance.Figures 4 to 6 are views of three other embodiments of such a protrusion.
Le porte-cartouche montré à la Fig. 1 comporte un corps 1 avec un logement 2 dans lequel est placée une cartouche 3 du type décrit dans la demande de brevet PCT/CH91/00222. Cette cartouche présente un bord supérieur 3a qui repose sur un anneau 4 logé, de façon élastique, dans le corps du porte-cartouche 1. Ce dernier est muni, à sa partie supérieure, de saillies 1a constituant des parties d'une fermeture à baïonnette permettant de fixer le porte- cartouche sur un dispositif de distribution d'eau chaude sous pression tel que la "douche" d'une machine à café espresso.The cartridge holder shown in Fig. 1 comprises a body 1 with a housing 2 in which a cartridge 3 of the type described is placed in patent application PCT / CH91 / 00222. This cartridge has an upper edge 3a which rests on a ring 4 resiliently housed in the body of the cartridge holder 1. The latter is provided, at its upper part, with projections 1a constituting parts of a bayonet closure allowing the cartridge holder to be attached to a pressurized hot water distribution device such as the "shower" of an espresso coffee machine.
Dans la partie inférieure du logement 2 est disposée une paroi filtre 5 présentant des protubérances 5a et des ouvertures 5b de passage pour le produit liquide. Un espace 2a situé entre la paroi filtre 5 et la partie inférieure du corps 1 permet de recueillir le produit liquide, le corps 1 comportant une ouverture 1 b pour l'écoulement de ce produit.In the lower part of the housing 2 is arranged a filter wall 5 having protuberances 5a and openings 5b for the passage of the liquid product. A space 2a located between the filter wall 5 and the lower part of the body 1 makes it possible to collect the liquid product, the body 1 having an opening 1b for the flow of this product.
La paroi de fond 3b de la cartouche 3 réalisée, par exemple, en une matière plastique, présente, dans l'exemple de la Fig. 1 , une forme bombée concave, l'agencement de cette paroi inférieure étant tel que celle-ci se déforme sous la pression du liquide introduit dans la cartouche lorsque cette pression atteint une valeur déterminée, cette pression poussant la paroi 3b contre les protubérances 5a et conduisant à son percement à l'endroit de ces protubérances. Le produit liquide qui se forme à l'intérieur de la cartouche au moyen du liquide introduit dans celle-ci par l'appareil sur lequel est fixé le porte-cartouche et de la substance contenue dans la cartouche, passe le long des flancs des protubérances 5a et à travers les ouvertures 5b pour être recueilli dans l'espace en forme d'entonnoir 2a.The bottom wall 3b of the cartridge 3 made, for example, of a plastic material, present, in the example of FIG. 1, a concave convex shape, the arrangement of this lower wall being such that it deforms under the pressure of the liquid introduced into the cartridge when this pressure reaches a determined value, this pressure pushing the wall 3b against the protuberances 5a and leading to its piercing at the place of these protuberances. The liquid product which forms inside the cartridge by means of the liquid introduced into it by the apparatus on which the cartridge holder is fixed and of the substance contained in the cartridge, passes along the sides of the protuberances 5a and through the openings 5b to be collected in the space in the form of a funnel 2a.
La Fig. 2 montre un exemple de la configuration donnée selon la présente invention aux protubérances 5a. Elle consiste en une pointe pyramidale qui comporte une creusure en forme de gorge 25 disposée à l'endroit d'une des arêtes de la pyramide et s'élargissant du sommet vers la base de la protubérance. La gorge 25 forme, avec les surfaces latérales adjacentes de la protubérance, des arêtes 25a et 25b. La Fig. 3 montre une autre forme d'exécution d'une protubérance en forme de pyramide pointue 5'a. Dans cet exemple, une gorge 35 est formée dans la surface latérale de la pyramide dans le sens de la pente de celle-ci et forme, avec cette surface latérale, des gorges 35a, 35b. La creusure 35 commence, dans cet exemple, en-dessous du sommet de la protubérance et s'étend jusqu'au pied de celle-ci.Fig. 2 shows an example of the configuration given according to the present invention to the protrusions 5a. It consists of a pyramidal point which has a groove-shaped recess 25 placed at the location of one of the edges of the pyramid and widening from the top towards the base of the protuberance. The groove 25 forms, with the adjacent lateral surfaces of the protuberance, ridges 25a and 25b. Fig. 3 shows another embodiment of a protrusion in the shape of a pointed pyramid 5'a. In this example, a groove 35 is formed in the lateral surface of the pyramid in the direction of the slope thereof and forms, with this lateral surface, grooves 35a, 35b. The recess 35 begins, in this example, below the top of the protuberance and extends to the foot of the latter.
La Fig. 4 montre un troisième exemple d'exécution 5"a d'une protubérance, ici en forme de pyramide à base rectangulaire présentant un sommet tronqué formant quatre pointes. La surface latérale de cette protubérance présente une partie en retrait 45 disposée à l'endroit d'une arête de la pyramide en formant, avec les parties de surface latérale adjacentes, des arêtes 45a, 45b.Fig. 4 shows a third exemplary embodiment 5 "a with a protuberance, here in the form of a pyramid with a rectangular base having a truncated apex forming four points. The lateral surface of this protuberance has a recessed portion 45 disposed at the location d an edge of the pyramid forming, with the adjacent lateral surface portions, edges 45a, 45b.
Les Figures 5 et 6 montrent deux autres formes d'exécution des protubérances d'un porte-cartouche selon l'invention. La protubérance 5'"a de la Fig. 5 est une pointe essentiellement pyramidale mais dont les faces latérales sont courbées, en l'occurrence légèrement concaves. Des creusures sous forme de gorges telles que 55, 56 dans les faces latérales permettent, de façon encore plus prononcée que dans les autres exemples donnés ici, un écoulement à débit progressif du produit liquide lorsque la protubérance a percé la paroi de fond de la capsule et la pression à l'intérieur de la cartouche pousse cette paroi en direction de la base de la protubérance.Figures 5 and 6 show two other embodiments of the protrusions of a cartridge holder according to the invention. The protrusion 5 '"a of FIG. 5 is an essentially pyramidal point but the lateral faces of which are curved, in this case slightly concave. Hollow grooves such as 55, 56 in the lateral faces allow, in a way even more pronounced than in the other examples given here, a flow at a progressive flow rate of the liquid product when the protuberance has pierced the bottom wall of the capsule and the pressure inside the cartridge pushes this wall towards the base of protuberance.
La protubérance 5ιva de la Fig. 6 est en forme de coin et présente sur deux faces latérales des gorges telles que 65, 66 jouant un rôle similaire à celui des creusures ou parties en retrait des exemples précédents.The protrusion 5 ιv a of FIG. 6 is wedge-shaped and has on two lateral faces grooves such as 65, 66 playing a role similar to that of the recesses or recessed parts of the previous examples.
Les formes d'exécution susmentionnées ne sont que des exemples destinés à illustrer la présente invention, étant entendu que différentes formes géométriques et profondeurs peuvent être choisies pour la creusure ou partie en retrait des surfaces latérales des protubérances 5a. D'autre part, plusieurs creusures ou parties en retrait peuvent être prévues dans chaque protubérance et leurs inclinaisons peuvent varier dans une large mesure. En outre, les formes pyramidales des protubérances montrées à titre d'exemples peuvent être remplacées par des formes coniques ou tronconiques, ou par d'autres formes permettant le percement de la paroi de fond de la cartouche lors de la déformation de celle-ci.The above-mentioned embodiments are only examples intended to illustrate the present invention, it being understood that different geometric shapes and depths can be chosen for the recess or part set back from the lateral surfaces of the protrusions 5a. In addition, several recesses or recessed parts can be provided in each protuberance and their inclinations can vary to a large extent. In addition, the pyramidal shapes of the protrusions shown by way of examples can be replaced by conical or frustoconical shapes, or by other shapes allowing the bottom wall of the cartridge to be pierced during the deformation of the latter.
Les ouvertures de la paroi filtre peuvent être disposées entre les protubérances ou au pied de celles-ci, ou encore être reliées à la base des protubérances par des rigoles pratiquées dans la surface de la paroi filtre.The openings of the filter wall may be arranged between the protrusions or at the foot thereof, or may be connected to the base of the protrusions by channels formed in the surface of the filter wall.
La présente invention permet ainsi de réaliser un filtrage régulier d'une cartouche à l'autre, ce qui contribue à assurer une qualité constante du produit liquide obtenu. The present invention thus makes it possible to carry out regular filtering from one cartridge to another, which contributes to ensuring a constant quality of the liquid product obtained.
