The funnel of claim 4, further comprising a first plurality of teeth formed axially on each cam body lobe and a second plurality of axial teeth formed on said housing wall of said ramped recesses, wherein a. said first plurality of teeth interact with said second plurality of teeth, and b. said first and said second plurality of teeth allow said housing body to be rotated with respect to said cam body in a first direction but rotationally fix said housing and said cam body in an opposite second direction. 6. The funnel of claim 3, wherein said cam body valve wall is frustoconical in shape and said valve portion is frustoconical in shape so that said frustoconical valve portion is received adjacent to said frustoconical cam body valve wall. 7. The funnel of claim 1, wherein a. said housing has a first end proximate said neck portion and an opposite second end distal from said neck portion; and b. said generally cylindrical housing wall has a plurality of axial slots formed therethrough extending from said housing second end approximately along two-thirds of the axial length of said housing; wherein said cam surface is located proximate said housing second end. 8. The funnel of claim 7, wherein a. said plurality of axial slots define a plurality of flexible fingers each defined by a portion of said housing wall located between adjacent axial slots, and b. each finger moves radially outward changing said diameter of said housing axial bore between said first diameter and said second diameter. 9. The funnel of claim 1, wherein said cam body is rotationally and axially fixed to said neck portion, and said housing is rotatable and axially moveable with respect to said cam body. 10. The funnel of claim 9, wherein when said housing is moved axially with respect to said cam body, said at least one cam surface disengages from said housing wall allowing said diameter of said housing axial bore to change from said larger second diameter to said first diameter. 11. The funnel of claim 1, further comprising a flexible layer of material disposed on an outer surface of said housing. 12. A funnel comprising: a. a receiving chamber having a first open end and an opposite second end; b. a neck portion coupled to said second end, said neck portion having an axial bore formed therethrough that is in fluid communication with said receiving chamber; c. a connector coupled to said neck portion, said connector comprising, (i) a housing having an axial bore formed therethrough that is defined by a housing wall, said axial bore having a first diameter, (ii) a cam body having a plurality of cam surfaces in operative engagement with said housing wall, and an axial bore formed through said cam body that is defined by a cam body wall, said cam body axial bore being in fluid communication with said neck portion axial bore, wherein said cam body is received in said housing axial bore so that when said cam body is moved with respect to said housing, said plurality of cam surfaces bias said housing wall so that said housing axial bore diameter changes from said first diameter to a larger second diameter; and d. a valve operatively disposed between said neck portion axial bore and said cam body axial bore, wherein said valve is moveable between an open position and a closed position. 13. The funnel of claim 12, said valve comprising: a. an elongated rod having a first end and an opposite second end; and b. a valve portion located on said elongated rod second end, said valve portion having an opening formed therethrough, wherein said elongated rod first end is coupled to said receiving chamber and said valve portion is received in said cam body axial bore so that said valve portion operates to allow or block fluid flow through said funnel. 14. The funnel of claim 12, wherein a. said cam body is rotationally and axially fixed to said neck portion, and b. said housing is rotatable and axially moveable with respect to said cam body. 15. The funnel of claim 12, wherein a. said housing has a first end proximate said neck portion and an opposite second end distal from said neck portion; and b. said housing wall has a plurality of axial slots formed therethrough extending from said housing second end along the axial length of said housing toward said first end; wherein said plurality of axial slots define a plurality of flexible fingers each defined by a portion of said housing wall located between adjacent axial slots, and each finger moves radially outward when one of said plurality of cam surfaces engage said finger changing said diameter of said housing axial bore between said first diameter and said second diameter. 16.
