Abstract

The cafeteria has a transparent cylindrical container which has a lid with a hole to guide the plunger (j). One filter has the same diameter as the interior of the container and is joined to a solid rod. A second filter has the same diameter as the first filter and is joined to a hollow rod. This slides on the solid rod and is joined to the plunger

Description

La présente invention concerne une cafetière à piston et à filtre de'type classique, caractérisée par l'ajout à son système d'un second filtre, ajout qui permet de substituer, - à l'effet-infusion de la mouture de café, produit par ce type de cafetière, opération qui laisse au café ainsi obtenu un arrière-goût, dit "de marc", - un effet-filtration, conservant au café élaboré tout son arôme, sans arrière-goût de marc. The present invention relates to a conventional piston and filter coffee machine, characterized by the addition to its system of a second filter, an addition which makes it possible to substitute for the infusion effect of the coffee grounds, product by this type of coffee maker, an operation which leaves the coffee thus obtained a after-taste, called "de marc", - a filtration effect, preserving the elaborate coffee all its aroma, without any after-taste of marc.

Le dispositif, selon l'invention, comprend, - un récipient cylindrique transparent destiné à recevoir l'eau chaude, - un premier filtre de mème diamètre que le recipient, assorti d'un axe massif, - un second filtre de mème diamètre que le précedent, assorti d'un axe creux de diamètre interieur correspondant au diamètre de l'axe du premier filtre, - un poussoir, vissé ou fixé à l'extrémité de l'axe creux du second filtre. The device according to the invention comprises: - a transparent cylindrical container intended to receive hot water, - a first filter of the same diameter as the container, with a solid axis, - a second filter of the same diameter as the preceding, together with a hollow shaft of inner diameter corresponding to the diameter of the axis of the first filter, - a pusher, screwed or fixed to the end of the hollow axis of the second filter.

- un couvercle percé d'un orifice destiné au guidage des axes des filtres, durant l'opération de filtration.- A lid pierced with a hole for guiding the axes of the filters, during the filtration operation.

Les dessins joints, tous de profil, illustrent l'invention.  The accompanying drawings, all in profile, illustrate the invention.

Sur ces dessins,
- la figure 1 représente le récipient, ( a et son couvercle, ( m - la figure 2 représente le premier filtre, ( b assorti de son axe plein, ( c ) - la figure 3 représente le second filtre, ( d assorti de son axe creux, ( e ), et du poussoir, ( n ).On these drawings,
FIG. 1 shows the container, (a) and its lid, (m - FIG. 2 represents the first filter, (b) with its solid axis, (c) - FIG. 3 represents the second filter, (d with its hollow shaft, (e), and pusher, (n).

En reférence à ces dessins, - la figure 4 illustre l'emplissage du recipient d'eau frémissante ( f ), - la figure 5 illustre le placement du premier filtre, ( g ), destiné à séparer l'eau chaude de la mouture de café, - la figure 6 illustre le placement de la dose optimale de mouture de café, ( h ) - la figure 7 illustre le placement du second filtre, ( i ), destiné à compresser cette mouture contre le premier filtre, durant l'opération de filtration, - et la figure 8 illustre, en fin d'opération
de filtration, la poussée qui a été exercée sur le poussoir ( j ), le café élaboré, ( k ) et son marc résiduel, ( 1 ). With reference to these drawings, FIG. 4 illustrates the filling of the simmering water container (f), FIG. 5 illustrates the placement of the first filter, (g), intended to separate the hot water from the ground coffee. coffee, - Figure 6 illustrates the placement of the optimum dose of ground coffee, (h) - Figure 7 illustrates the placement of the second filter, (i), for compressing this grind against the first filter, during the operation filtration, - and Figure 8 illustrates, at the end of operation
filtration, the thrust that has been exerted on the pusher (j), the coffee developed, (k) and its residual marc, (1).
