Abstract

A conventional funnel that has a rimmed open bowl atop a spout, to guide a fluid flow poured in from a fluid-contributing source or container into a fluid-receiving container, is improved by the provision of a curved-in lip around the bowl rim. The curved-in lip intercepts any fluid seeking to splash out of the funnel for a variety of reasons, and redirects it back into the bowl to counter undesirable splash-out. The curved-in rim, even when of very small span, is effective in countering splash-out of true liquids, mixtures of non-sticking solid particulates in a liquid, dry flowing particulates and even small sized objects like peanuts. The provision of a perforated collar at the junction of the bowl and the spout, a flexible portion provided to the spout adjacent the same junction, and a plurality of outwardly extending vanes provided outside the spout, and flutes formed in the bowl to promote Coriolis-acceleration-influenced flow, added individually or in selected combinations, variously improve the funnel further by making it more securely locatable with respect to the receiving container, facilitating venting of displaced air therefrom, and promoting fluid throughflow via the funnel.

Description

FIELD OF THE INVENTION

[0001] This invention relates to improvements to a conventional funnel, of the kind commonly used to help guide a fluid flow from a fluid-contributing container into a fluid-receiving container, to counter out-splashing from the funnel as the fluid is being poured through it. More particularly, it relates to simple structural improvements to a conventional funnel that significantly reduce the natural tendency of a fluid being poured through it to splash away from the intended transfer flow and out of the funnel due to factors such as: (a) the funnel not being held upright during the pour; (b) unevenly oriented or pulsating flow out of the contributing container, (c) inertial forces that tend to bounce back fast-pouring fluid from the inner surface of the funnel and over the funnel rim, (d) upward blowback of air and / or vapor from the receiving container, or (e) inadvertently caused instability of the funnel body during the pouring operation.BACKGROUND OF THE REL...
