<p>The present invention refers to a suction device (1) for creating a vacuum inside containers, such as basins, glasses and the like, of the kind used to preserve perishable products and in particular foodstuff. The suction device (1) according to the invention comprises a vacuum pump, a motor (8) for actuating said pump and control systems all placed inside a single device designed to be placed on a table, as well as a detachable push rod (3), connected to said vacuum pump by a coil tube (4), suitable to couple to a valve element generally provided on the cover of the foodstuff containers, to link the inside of the container to the vacuum pump when the device is actuated. The fact of having all the devices placed inside a single apparatus, which is separate from the push rod (3) and designed to be placed on a table, permits to create more powerful and noiseless, and at the same time more user-friendly, suction devices, since the user has to handle only one push rod for the connection to the container and not a device, which comprises also the motor and different suction systems, which would be more bulky and heavier.</p> |
