Patent number: 10246316Abstract: An anti-spill funnel assembly which includes an outer reservoir funnel having a center funnel positioned therein. The outer reservoir funnel includes a cone-shaped portion having a spout extending downwardly therefrom. The center funnel includes a cone-shaped portion having a hollow stem extending downwardly therefrom. This center funnel also includes a spout extending downwardly from the lower end of the cone-shaped portion thereof. The hollow stem portion has a plurality of vertically disposed slots formed therein. When the funnel assembly is being used to fill a container or a piece of equipment, the spouts of the reservoir funnel and center funnel are inserted downwardly into the fill opening of a container or equipment. As liquid is poured into the container or equipment, any overflow liquid is passed upwardly into the outer reservoir funnel to prevent a spill.Type: GrantFiled: July 13, 2017Date of Patent: April 2, 2019Assignee: J.N.S. TECHNOLOGIES, LLCInventors: Nathan D. Winters, John A. Cain, Samuel R. White

Patent number: 9138108Abstract: A bar soap holder is provided that includes a support base to allow dislodgement of a soap bar without substantial movement of the bar soap holder. The bar soap holder further includes a holder body coupled to the support base. The holder body defines an upper central opening dimensioned for receiving the soap bar. The soap holder body includes a first support surface and an opposing second support surface disposed within an interior region of the soap holder body for supporting the soap bar. The first and the second support surfaces are positioned at a tapered incline angle greater than 25° relative to a horizontal plane. The holder body further defines a drain path from the first and second support surfaces to the reservoir. The bar soap holder further includes a reservoir for collection of soap water that is coupled to the support surfaces by the drain path.Type: GrantFiled: November 23, 2011Date of Patent: September 22, 2015Inventor: Henry D. Pixley

Patent number: 6874550Abstract: Gravity fill line vent fitting includes a body member having a water fill opening and vent opening adapted to be connected to the elevated ends of a water fill line and surrounding air vent line, respectively, of a potable water storage tank. An inner tubular extension and surrounding hose fitting may be connected to the inner/bottom side of the body member for use in attaching the water fill line and air vent line, respectively, to the body member. An outer tubular extension and surrounding service fitting may be connected to the outer side of the body member. A cap is insertable over the service fitting for sealing off both the water fill opening and vent opening.Type: GrantFiled: April 24, 2003Date of Patent: April 5, 2005Assignee: Goodrich CorporationInventor: Steven C. Brooker

Patent number: 6315011Abstract: Dual cone funnel assembly for simultaneously introducing a flow of particulate composition, or powder, into a receiving container through a dispensing tube along one path while channeling the flow of displaced air through an annular air-exhaust space along a different path surrounding the first path. The funnel assembly has an inner funnel supply element surrounded and closely-spaced from an outer funnel element to provide the annular air-relief space therebetween. The assembly may be used to feed particulate resinous extrusion composition through a dispensing funnel element to the premelt chamber of an extruder and to isolate and return the displaced air to a dust collection element.Type: GrantFiled: July 10, 2000Date of Patent: November 13, 2001Assignee: Xerox CorporationInventor: Mark J. Smith

Patent number: 6119739Abstract: A funnel assembly which includes an interior funnel and an exterior funnel. When an interior funnel is inserted into the exterior funnel, three equally spaced raised projections prevent contact between the outer surface of the interior funnel and the inner surface of the exterior funnel. This arrangement creates air passages between the two funnels for the venting of displaced air. Consequently, the liquid being poured runs faster into a container, unaffected by the upward movement of the vented air. The interior and exterior funnels are individually, integrally formed and come together as the exterior funnel is snapped into place next to the interior funnel by three wedges protruding on the outside spout of the interior funnel. These wedges are forced against the spout of the exterior funnel and hold the two funnels equidistant to each other.Type: GrantFiled: October 19, 1999Date of Patent: September 19, 2000Inventors: Mark J. McGee, Joel T. Hoffman

Patent number: 5277234Abstract: 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.Type: GrantFiled: March 15, 1993Date of Patent: January 11, 1994Inventor: Christopher L. Warstler

Patent number: 5133481Abstract: A disposable plastic bottle used to contain fluid substances having an integral, flexible funnel spout, with sealable opening, featuring an external air vent integrally formed into the mouth of the spout suitable for accurately transferring fluids through tight filler openings which would ordinarily require the use of a separate funnel or spout. When the mouth of the spout is snugly inserted into a receptacle, the external air vent will provide a direct air passage to the contents of the bottle allowing the liquid to flow smoothly without restriction. The spout is integrally formed atop the bottle and comprises a plurality of bellows like ribs. Such ribs have a thinner cross-sectional wall than the side walls of the container body. This permits the spout to be flexed, enabling the ribs to collapse over-center and fold, allowing the spout to retain the flexed condition without external assistance, thereby creating a self latching feature.Type: GrantFiled: January 25, 1991Date of Patent: July 28, 1992Inventor: Todd A. Mayfield

Patent number: 4182591Abstract: Apparatus for transferring pulverulent or granular material from an opening at the lower end of a silo into a vessel which is moved to a position below such opening has a vertical duct with a rigid upper section which is affixed to the silo, a rigid lower section which is surrounded by and is rigidly connected to a downwardly tapering funnel and serves to discharge flowable material into the vessel by way of an opening in the top wall of the vessel, and a bellows which is disposed between and is separably connected with the two rigid sections. The lower section and the funnel are movable up and down by means of a winch and several cables or chains whose lower end portions are attached to the funnel and/or to the lower section. A cover which normally overlies the open upper side of the funnel is movable to a raised position in which it surrounds the upper section of the duct.Type: GrantFiled: February 27, 1978Date of Patent: January 8, 1980Inventor: Karl-Heinz Stanelle
