ABSTRACT:
A threaded jar funnel for easy pouring of material into a jar, without leakage or spillage, has an upper part, with upper and lower conical segments, and a lower cylindrical part having threads on the inside. The upper conical segment of the upper part has a small angle to the vertical and the lower conical segment has a larger angle to the vertical than the upper conical segment. The upper conical segment merges into the lower conical segment to provide an aesthetically pleasing appearance, larger funnel capacity and smoother flow of contents into a jar coupled to the funnel. The lower cylindrical threaded part has a rim, which provides a tight seal when the funnel is coupled to a jar.
