Abstract A funnel comprises a downwardly tapered generally frustoconical shell and a tube extending along the axis of the shell and having an open lower end adjacent the lower outlet of the shell and an upper end above the upper mouth of the shell. The tube is straight and is formed between its ends with a lateral opening. A pair of arms support a sleeve in the center of the shell which embraces the tube, this sleeve being formed with a downwardly extending skirt surrounding the tube at the level of the lateral opening. The tube is limitedly axially displaceable relative to the shell and is provided at its upper end with a handle engageable with the support sleeve and at its lower end with an upwardly tapered valve body sealingly engageable in the outlet of the funnel so as to prevent fluid flow therefrom. The funnel is filled with a liquid when the valve body is lifted up against the outlet, then the funnel is set on a vessel to be filled and the valve body and tube are lowered in order to allow the liquid to flow out of the outlet opening while allowing air in the vessel to escape upwardly through the tube. Liquid entrained by the upwardly rising air exits from the tube at the lateral opening and does not sprinkle the user.
A funnel comprising: a downwardly tapered shell having a narrow lower outlet and a wide upper mouth; a tube extending substantially through said shell and having an open lower end adjacent said outlet and an upper end above said mouth, said tube being straight and formed between said ends with a lateral opening; a support on said shell spanning said mouth holding said tube around said upper end thereof; and a downwardly extending tubular annular skirt on said support spacedly surrounding said tube at the level of said opening whereby fluid rising in said tube and issuing from said opening is deflected by said shield into said shell.

Claim 3
Dependent Claim
57 words
The funnel defined in claim 1, wherein said shell is a body of revolution having an axis, said tube lying on said axis and being limitedly axially displaceable, said funnel further comprising an upwardly tapered valve body at said lower end of said tube and engageable sealingly in said outlet in a lifted position of said tube.
Claim 4
Dependent Claim
30 words
The funnel defined in claim 2, further comprising a handle on said upper end of said tube above said sleeve and engageable therewith in a depressed position of said tube.
Claim 5
Dependent Claim
33 words
The funnel defined in claim 3 wherein said handle is formed with a throughgoing hole registering with the passage through said tube, whereby fluid in said tube can issue therefrom through said handle.
Claim 6
Dependent Claim
33 words
The funnel defined in claim 3 wherein said handle blocks said upper end of said tube, whereby fluid entering said lower end of said tube can leave said tube only through said opening.
Claim 7
Dependent Claim
24 words
The funnel defined in claim 3 wherein said valve body is formed with an outwardly directed fluid-deflecting flange extending substantially orthogonally from said axis.
Claim 8
Dependent Claim
26 words
The funnel defined in claim 3 wherein said valve body is formed with a downwardly flared opening communicating and aligned with the passage through said tube.
