  • Patent number: 11027955
    Abstract: An apparatus with a two vents funnel for the transfer and preservation of juices comprising removable vents and outlet extensions at the funnel base; an asymmetrical funnel bowl separated into a main and an overflow chamber, with a pouring lip and its narrow end; a purposefully narrow funnel outlet, with its extension reaching the container's wall during transfer; its seal at the funnel's base with a stop ring; a mesh filter which can be fitted onto the funnel's bowl; and a stand, with an anti-drop plate at its base, which can hold the funnel whereby a user can do the precise transfer of a juice into a receiving container using the seal's stop ring for horizontal alignment and the overflow chamber filling as a clear indication as to when the transfer is complete, this transfer is made bubble-free having the outlet purposely slowing down the flow while at the same time releasing the juice close to the container's inner wall, thus enabling said juice long-term preservation, any leftover into the overflow chambe

  • Patent number: 10246316
    Abstract: 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.

  • Patent number: 9138108
    Abstract: 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.

  • Patent number: 6315011
    Abstract: 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.

  • Patent number: 6119739
    Abstract: 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.

  • Patent number: 5133481
    Abstract: 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.
