Abstract: A hydraulic circuit (1) for use on machines for making beverages includes a pump (3), a boiler (4) and an infusion chamber (5), the pump (3) being arranged so as to pressurize a liquid contained in a section of the circuit between the pump (3) and the infusion chamber (5) and including boiler (4). The circuit includes a depressurizing device (10) to allow a portion of the liquid to be discharged outside the section on liquid depressurization, the depressurizing device (10) being arranged so that the portion of the liquid does not come into contact with the boiler (4) when pressurizing the liquid.

Abstract: A device for production of a beverage by infusion of a ground substance for infusion includes an infusion chamber (2), for housing the ground product, a hot water circuit through the infusion chamber (2) and elements for circulating the hot water in the circuit. The device includes elements for reversing the flow of the hot water circuit through the infusion chamber (2).

Abstract: A packaging article for a substance to be infused, includes two layers (2, 3) of filter material enclosing a reinforcement sheet (4) equipped with a hole (5). This packaging is such that it includes a hollow cylindrical part (6) for transverse stiffening, the outer wall of which is placed on the hole (5) of the reinforcement sheet (4), and delimiting, with the layers (2, 3), a volume for receiving a substance to be infused. Application to pre-dosed packages of a substance to be infused, such as ground coffee or tea leaves.

Abstract: A device for the production of beverages by infusing a substance that is to be infused and which is contained in disposable packaging, includes: an infusion chamber having a configuration which can vary between an open position and a closed position for the infusion; elements for guiding the packaging from an introduction area (7) towards the infusion chamber, the guiding elements including a slide (6) which can cooperate with the periphery of the packaging, characterized by the fact that the inventive device includes elements (9) for detecting an identification marking on the packaging, the detection elements (9) being formed in the slide (6). The device is applicable to coffee machines using packaging provided with marking for identification purposes.

Abstract: A device for producing beverages by infusion of a ground product, includes an infusion chamber capable of receiving the ground product and a hot water circuit passing through the infusion chamber. Characteristically, the device includes at least one additional infusion chamber placed in series with the first infusion chamber in the hot water circuit.

Abstract: A package (1) for brewing a substance to be brewed includes two superimposed filter paper layers (2, 3) defining a volume for receiving the substance to be brewed (4) and each integral with a peripheral reinforcing surface (5), the package (1) including a mark for identification. The invention is characterized in that the marking is performed on at least one surface of the peripheral reinforcement (5).

Abstract: A device for the production of beverages such as coffee by infusion of a product contained in a tablet includes an infusion chamber adapted to receive such a tablet (2) and has two portions (3, 4) arranged to move toward or away from each other to close or open the infusion chamber. Only one of the portions has mobility in rotation adapted to place the tablet (2) in abutment in the portion, the portion (3) movable in rotation having mobility in translation to open or close the infusion chamber, and having common drive elements for the mobility in translation and the mobility in rotation of the movable portion (3). The drive elements having a rotatable drive shaft (13) coupled to the movable portion (3) by at least one rod (14a, 14b) mounted pivotably between the drive shaft (13) and the movable portion (3).

Abstract: The automatic machine for the preparation of hot beverage infusions such as coffee being formed by a group formed of a body facing a boiler intended to be brought closer to each other in order to form an infusion chamber. The machine having, between the body and the boiler, at the infusion chamber: reception members intended to receive an individual package containing the product to be infused, the reception members being intended to secure temporarily the package between the body and the boiler; a position fixing element for guiding and maintaining the package in a vertical position when the reception members are present; and an automatic ejection member which ejects the package simply by gravity, the displacement of the package being perpendicular to the axis of the machine.

Abstract: A package for granular material, particularly coffee beans, of the type of a metal can (1) with a withdrawable neck (2) of flexible plastic secured by a ring (3) clamped on the opening (4) of the can (1). The can comprises cone (5) at this level, and a protective snap-on cap (7) that snaps on to the metal part of the clamping ring (3) which protects the withdrawable neck (2), itself closed by a screw cap (8) and between the neck (2) and the threaded cap (8) there is an apertured ring (9) of a valve which serves as a cap release valve. The end of the withdrawable neck (2) is screw threaded and receives a device serving as a dispensing connecting closure (12) which comprises, at its first end, an adapter cone (13) followed by a screw-threaded cylindrical portion (14) which permits securement to a screw-threaded end (11) of the neck (2). The adapter cone (13) of the connector closure (12) is sufficiently large that the can (1) will be stable when supported by its cone (5) on the connector closure (12).
