A container filling device including a body having a top end, a bottom end, a first opening at the top end, a second opening at the bottom end, and a channel formed there between is provided in an embodiment herein. A diameter of the body at the top end is greater than a diameter of the body at the bottom end, and a rod component is disposed within the channel and is slidable within the channel, the rod component having a first end and a second end, an indicator element is disposed toward the first end of the rod component and a contact element is disposed toward the second end, wherein upon filling the container with a fluid, the contact element remains at the surface of the fluid, and the indicator element visually indicates the level of the fluid in the container.

A device is provided for the controlled and precise delivery of powders, including cohesive powders, based on a fluidization technique to directly reduce inter-particle friction and using a fluidizing gas as an air-bearing. The device preferably includes no moving parts, no sealing gaskets or sealing surfaces. Unlike mechanically actuated valves, the powders dispensed by the current device do not experience mechanical shearing, thereby reducing wear and thus increasing the service life of the apparatus.

An apparatus for minimizing spilling of liquids poured into a container, the apparatus comprising a funnel structure and a float member. The funnel structure has an open top portion extending to a flow aperture open into a spout extending downwardly beyond an almost-full level. The float member is movable within the spout and configured and dimensioned such that a float top is forced into a sealing engagement with the flow aperture by a liquid reaching the almost-full level below an empty head space reserved for draining the liquid from the top portion by lifting the funnel structure thus disengaging the flow aperture from the float member. The top portion may have a frusto-conical shape tapering from an open mouth to the flow aperture.

A flow control device includes a flow channel composed of non-magnetic material having a center axis, a first length segment having a first diameter, a second length segment, wherein the flow channel expands conically from the first diameter to a second diameter in the second length segment, and a third length segment; a magnetic closing ball, which is movably arranged in the second and third length segments and has a ball diameter that lies between the first and the second diameters; a first, axially polarized (north-south) ring magnet, which is oriented centrally in the center axis and is arranged so as to be longitudinally movable along the center axis and has an inside diameter that is greater than the outside diameter of the flow channel in the third length segment; and a preloading device, which axially pushes the north-south-polarized first ring magnet toward the first length segment.

A weighted funnel, the weight assisting to keep the funnel substantially upright, the weight comprising a periphery defining an internal void, the void receiving the neck of the funnel. The neck of the funnel is threaded externally while the weight is threaded internally (in the void) so that the threads engage each other, securing the weight in place. Other embodiments allow for alternate methods of securing the weight.
