Device for pumping a liquid from a packaging or a container.

Abstract

The invention relates to a device for pumping liquid from a package (5) for dispensing the liquid in heated, foamed or emulsified form, the device comprising a venturi-type suction member adapted to be connected to a pressure A nozzle for carrying a fluid generator, said suction part comprising a body (4, 50, 52) having a carrying fluid introduction conduit (21, 27) leading into a suction chamber (25) and at least one outlet for suction. A suction tube (33) for sucking liquid contained in a package (5), characterized in that the suction part includes a nozzle (1, 2, 3) and a fixing and opening device (13, 15, 30), This fixing and opening device connects the nozzle (1, 2, 3) to the package (5) and puts the suction tube (33) into communication with the liquid inside the package (5). The invention is used for preparing cappuccino or other foaming beverages.

Description

technical field

[0001] The present invention relates to a device for pumping liquid from a package by venturi action in order to dispense it in foamed or emulsified and if necessary heated form. Although the invention relates preferably to the food sector producing milk-based emulsified beverages, the invention is by no means restricted to the food sector, but can be applied to all products that can be pumped from a package, such as cosmetics in the form of pumpable creams Wait. Background technique

[0002] "Device having venturi action" means a pumping element for at least one pumpable state, typically a liquid, comprising a chamber, an introduction tube for fluid pressurized by a constriction (constriction) access to the chamber so as to generate suction by depressurization at the outlet of the constriction in at least one tube connecting said chamber to a package containing a pumpable liquid, the carrier (medium, carrier) fluid may be a gas or Liquids such as steam, ho...
