Abstract
A funnel includes a truncated conical funnel head directed into a cylindrical guide conduit, with the guide conduit and funnel head oriented about a predetermined axis, and wherein a plurality of spaced parallel channels are directed into the funnel head and the guide conduit extending from a lowermost end of the funnel structure to an uppermost end thereof permitting venting when the funnel is directed within an opening of an associated container.
Claims2
A self venting funnel, comprising,
- a truncated conical funnel head, having an annular entrance periphery of a first diameter, and an exit funnel head end of a second diameter less than the first diameter, with a cylindrical guide conduit fixedly mounted to the exit funnel head end, having a guide conduit diameter equal to the second diameter, and the guide conduit includes a guide conduit exit end spaced from the funnel head end, and
- the funnel head and the guide conduit are symmetrically oriented about a predetermined axis, and
- a plurality of spaced vent channels are directed into an exterior surface of the funnel head and the guide conduit extending in a parallel relationship relative to one another and to the predetermined axis, and extending from the annular entrance periphery to the guide conduit exit end, and
- each of the vent channels project within the funnel head and the guide conduit to provide for guide ribs directing lamina flow through the funnel head and the guide conduit of fluid directed into the funnel head, and
- a truncated conical shield having a shield first end of a third diameter less than the first diameter and greater than the second diameter, defining a shield entrance opening therewithin, with the shield having a shield second end, the shield second end having a second end diameter equal to the first diameter, and wherein the shield second end is formed of a ferrous metallic material, and wherein the annular entrance periphery of the funnel head is formed of ferromagnetic material for selective adherence of the shield to the funnel head.
