Abstract
An improved funnel, comprising a shutter valve of the passageway in the outlet pipe or ridge provided with a closing cone, characterized in that the cone (5) of the sealing valve, which acts against a seat (4) arranged in the the inlet mouth of said duct, is integral with a rod (6) that axially crossing said tube (3) throughout its length, is joined at its end opposite the cone to two other rods (7, 7 ') parallel to it and shorter than the same, arranged by the outer part of the mentioned tube, these outer rods being associated by their upper end with a washer (8) that surrounds the outlet pipe or pipe (3) and that is capable of sliding in direction axially together with the rods (7, 7 ', 6) and the cone of closure (5) mentioned, all with the purpose that the aforementioned cone (5), when the funnel is held by its body, remains applied by gravity against the corresponding seat (4), closing the way to liquid, and separates from said seat, opening the passage to the liquid, when the funnel is placed in a container and leans against the mouth of this through the aforementioned washer (8).
