   La   présenté   invention-a pour'objet un nouveau filtre individuel à café. 



   Ce nouveau filtre, pourvu- d'une manière connue en soi de deux grilles entre   lesquelles   est serré le 
 EMI1.1 
 c2f' boulet, -est" caractérisé par le fait :...11. t il comporte des   soyons     pour   faire passer sous pression l'eau au travers desditesgrilles.

  Suivant une fome cl3 : 1? W.?t? cn ûve.nta:":-;LliJ0 do l'invention, ces moyens cent constitué par un piston ciiboîtc de lanière étanche c1.f!l1 le corps du filtre, ledit 

 <Desc/Clms Page number 2> 

 piston pouvant coulisser axialement à l'intérieur dudit corps. 



   Selon une   caractéristique   de l'invention, le piston comporte au. moins   un ^     plaquette   rigide bordée périphériquement   par   un   .joint   souple, ladite plaquette étant rendue solidaire d'une tige do   commande   passant au travers du couvercle du filtre et terminée par un bouton   (le   manoeuvre. 



   D'une   Manière   avantageuse, le couvercle est Mini      on son centre de moyens, de   guidage   axial de la tige du piston.   @   
L'invention sera bien   comprise   en se référant au dessin   annexé,   représentant   à   titra d'exemple non limi- tatif, un mode de   réalisation   de l'invention. 



   La figure unique   représente   en élévation, avec arrachement partial et en coupe, un filtre individuel conforme à   l'intention.   



   Dans le mode de réalisation représenta au dessin annexé, on voit en 1 le corps de filtre dont le   fond 3   constitue grille. Sur ce fond, est vissée une grille amovible de serrage 3 pressant la poudre de café 4. 



     Conformément   à l'invention, il est prévu dans le corps 1 un piston constitué par deux plaquettes 5 et 6 maintenant une membrane élastique 7, dont la périphérie 7a est avantageusement recourbée, Vers le bas, de manière   rassurer   une étanchéité suffisante. 



   Ce piston est solidaire d'une tige 8 traversant le couvercle 9 et terminée par un bouton de manoeuvre   10.   



  Pour guider axialement le piston lors de son déplacement dans -le corps du filtre, on a prévu sur le couvercle 9 

 <Desc/Clms Page number 3> 

 une bague 11 réalisant un contact d'une certaine longueur sur la tige 8. 



     L'utilisation   du filtre conforme à l'invention peut se faire de la manière suivante :   ',près   avoir serré le café sous une pression relativement élevée, on verse une petite quantité d'eau pour l'imbiber et le faire   "gonfler";   après environ deux minutes, on verse dans le filtre la quantité d'eau complémentaire, puis on introduit le piston dans le corps de filtre. Par poussée verticale sur le bouton 10, le piston est chassé vers le bas jusqu'au fond du filtre, et l'eau passe au travers du café moulu, en se chargeant des essences et arômes. 



   Il va de soi que l'on peut, sans sortir du cadre de la présente invention, apporter toute modification aux formes de réalisation qui viennent d'être décrites, En particulier, on pourrait prévoir d'autres moyens qu'un piston pour chasser   l'eau   au travers des grilles. De même, le principe de l'invention pourrait être appliqué à des filtres ou cafetières de grand modèle, et l'on pourrait adapter sous le filtre tout type de récipient (et non une tasse) muni d'un bec-verseur pour le service.

   The present invention has pour'objet a new individual coffee filter.



   This new filter, provided in a manner known per se with two grids between which the
 EMI1.1
 c2f 'ball, -is "characterized by the fact: ... 11. t it comprises legs for making the water pass under pressure through said grids.
 EMI1.2
 



  Following a cl3: 1 form? W.?t? cn ûve.nta: ": -; LliJ0 of the invention, these means one hundred consisting of a piston ciiboîtc of tight strap c1.f! l1 the body of the filter, said

 <Desc / Clms Page number 2>

 piston slidable axially inside said body.



   According to one characteristic of the invention, the piston comprises at. at least one rigid plate bordered peripherally by a flexible .joint, said plate being made integral with a control rod passing through the filter cover and terminated by a button (the maneuver.



   Advantageously, the cover is Mini on its center of means for axial guiding of the piston rod. @
The invention will be well understood with reference to the appended drawing, representing by way of non-limiting example, an embodiment of the invention.



   The single figure shows in elevation, with partial cutaway and in section, an individual filter conforming to the intention.



   In the embodiment shown in the accompanying drawing, one sees at 1 the filter body, the bottom 3 of which constitutes a grid. A removable clamping grid 3 is screwed onto this base, pressing the coffee powder 4.



     According to the invention, there is provided in the body 1 a piston consisting of two plates 5 and 6 maintaining an elastic membrane 7, the periphery 7a of which is advantageously curved, downwards, so as to ensure sufficient sealing.



   This piston is integral with a rod 8 passing through the cover 9 and terminated by an operating button 10.



  In order to guide the piston axially during its movement in the body of the filter, 9

 <Desc / Clms Page number 3>

 a ring 11 making a contact of a certain length on the rod 8.



     The filter according to the invention can be used as follows: ', after having squeezed the coffee under a relatively high pressure, a small amount of water is poured in to soak it and make it "swell"; after about two minutes, the additional quantity of water is poured into the filter, then the piston is introduced into the filter body. By pushing vertically on the button 10, the piston is driven down to the bottom of the filter, and the water passes through the ground coffee, taking care of the essences and aromas.



   It goes without saying that it is possible, without departing from the scope of the present invention, to make any modification to the embodiments which have just been described, in particular, one could provide other means than a piston for expelling the water through the grids. Likewise, the principle of the invention could be applied to large model filters or coffee makers, and any type of container (and not a cup) fitted with a spout for the service could be fitted under the filter. .
