<p>The batching pimp can be used for pumping out and batching of mineral water or other liquids from bottles having 10-l content. It is of improved design, and in its operation the bottle is in natural position (not upside-down) and can be removed from one place to another, being held by its handle, wherein any leakage is excluded. The batching pump for mineral water is fitted to the neck of a bottle and is in the form of a polyethylene bag (1), closely wound by a threading to a connection cap (2) which on its turn is closely wound around, by threading, to bottle (5), wherein in the inner space on the side of the bag cap (2) has an intake valve (3) across which atmospheric air get through duct (7), and on the inner side on the side of the bottle, cap (2) has a release valve (4), connected by duct (8) to the interior of the bag. A polyethylene small pipe (6), breaking in two elbows (13) gets through the cap, which, on the inner side of the bottle reaches the bottom. The bottle is connected to the atmosphere by means of duct (10), the duct being permanently closed by a spring (11) and a lever-type valve (12), which, after pressing, equalized the pressure inside the bottle with the atmospheric pressure and thus any running out is terminated. The pumping out (batching) of different quantities of the liquid is possible depending on the volume of the bag and the number of the cycles of shrinking/extending of the bag. 1 claim, 1 figure</p> |
