<p>System for emptying packages with necks for liquids in the neck (1) of which is inserted a non-removal top (2) with a concentric tube (2.1) with a bottom (2.1.1), allowing the emptying of the package (7, 8) by: a tap (4) with an opening system using a leer type cam (4.1) joined to the interior of the concentric tube (2.1) with the necessary resistance for rotating the cam being provided by a circular bar (4.3) with a movable rod (4.4) which passes through the circular bar (4.3), guided by a central tube (4.3.1) joined at one end to the cam (4.1) and with the other end inserted in an elastic piece (4.5) which contracts or recovers its initial form when the rod (4.4) rises or descends, respectively, due to the operation of the cam (4.1) such that when the elastic piece (4.5) contracts, a tube (4.6.1) from the casing (4.6) of the tap (4.6.1) communicates with the narrowing (4.6.2) in the casing (4.6) allowing the liquid to exit to the exterior once a breaker (4.6.3) in the casing (4.6) has acted on the bottom (2.1.1).</p> |
