Abstract: A cartridge for obtaining a beverage by injecting into the cartridge a pressurized fluid, comprising a box-like body, which accommodates a substance from which it is possible to extract the beverage, and which accommodates on its inside an insert which separates the substance from a bottom wall of the box-like body, forming an interspace. The insert comprises an orifice for the passage of the beverage toward the interspace, whereas the bottom wall comprises a region which can be pierced to obtain an opening for the outflow of the beverage. In the interspace there is a basin which is arranged laterally with respect to the pierceable region in order to accumulate the beverage received directly from the orifice and make it flow out of the opening by overflowing.

Abstract: The invention concerns a device (1, 100, 101, 102, 103, 104, 105) for dispensing gas-liquid mixtures that can be associated with a container (C) of a liquid (L), comprising: suction means (2) suited to be moved from a first rest position to a second position in order to draw the liquid (L); a mixing chamber (3) communicating with the suction means (2), so that when the suction means are moved from the first position to the second position the liquid (L) is drawn and conveyed into the mixing chamber (3); compression means (5) for a gas (7). The compression means (5) comprise two chambers (5a, 5b) suited to contain the gas (7), communicating with the mixing chamber (3), so that when the suction means (2) are moved from the first to the second position part of the gas is conveyed into the mixing chamber (3).

Abstract: A liquid dispensing pump for a portable container in which the pump piston is disposed for lost motion in the pump cylinder between the plunger rod and a discharge valve carried by a stem affixed to the plunger rod and extending through the piston. The piston has upwardly and downwardly presented elastomeric skirts of which the lower skirt seats against the discharge valve on the piston upstroke and the upper skirt seats against a venting valve at the termination of the upstroke. Both the discharge valve and the venting valve exert an expanding action on the respective piston skirts incident to their seating relation with the skirts under the resilient pressure of the pump spring, to counteract any shrinking tendency of the skirts, and means are provided for limiting the expansion of the skirts. The upper and lower ends of the piston are symmetrically arranged to permit reversal of its position in the pump.

Abstract: A pump for delivery of gas-liquid mixtures adapted to be connected to a container for a liquid comprising: suction means adapted to be reciprocated between a first rest position and a second position so as to collect the liquid from the container; a mixing chamber in communication with the suction means so that when the suction means are moved from a first position to a second position, the liquid is collected from the container and conveyed into a mixing chamber; elastic means adapted to displace the suction means back in the first position after that the suction means are moved from a first position to a second position. The elastic means define a variable volume gas chamber in communication with the mixing chamber so that, when the suction means are moved from a first position to a second position, the gas is conveyed into the mixing chamber and a gas-liquid mixture is formed in the mixing chamber.
