Abstract: A dispensing closure in which the discharge passage is provided in an opening or openings in the side wall of the closure. The dispensing position of the closure is accomplished by it's elevation above the upper end of the container by a twist motion when equipped with threads to unscrew, or by a pull-up slide arrangement designed into the container and closure. It is returned by a reverse procedure to a closed and full sealing position for complete protection of the containers ingredients.

Abstract: A liquid dispenser for dispensing liquid from an inverted bottle into a tank at times when water in the tank drops below a buoying level. A hollow annular stationary member closes off the bottle's neck and has an annular diaphragm leading to a tube with seats at its upper and lower ends. A movable member has two portions that are slidable in the said tube and are joined by a measuring portion. It seats against one seat in its upper position with the measuring portion then wholly above the tube and against the other in its lower position, with the measuring portion then wholly below the tube, and it is moved between them by the change of water level in the tank. This movement is aided with a buoying skirt having an annular chamber that is normally filled with water and drains only after falling; the same chamber helps to dispose the measured charge of the other liquid.

Abstract: The construction of a container with a closure means wherein the closure means assembly will serve as a nozzle; as a drinking tube; and as a closure means.

Abstract: This invention relates to a closure member in the form of a hollow tubular outlet member and a cap fitting over the outlet member and rotatable relative thereto, the outlet member and cap having complementary conical end portions, an aperture in each conical end portion which can be aligned to define an opening which can be closed by rotation of the cap and wherein the cap and outlet have a co-axial tubular portion, one of such tubular portions being provided with at least one formation directed towards the other tubular portion and co-operating with a cam surface on the said other tubular portion, said cam surface being shaped such that the conical end portions are urged axially into tighter engagement with each other during rotation of the cap to close the opening.

Abstract: A fluid dispensing device comprising (a) a housing having a closed end, and opposite open end and fluid release opening extending through the wall of the housing; (b) an inner member adapted to contain a fluid and having one open end, an opposite closed end, a length substantially coextensive with the length of said housing and an outside cross-sectional dimension smaller than the inside cross-sectional dimension of the housing; the open end of the inner member being insertable in the open end of the housing thereby providing an annular space between the wall of the housing and the inner member; (c) the open end of the inner member being engageable with the closed end of the housing so as to form a first releasable seal to contain the fluid in the inner member; and (d) threads provided on the inner member adjacent its closed end and engageable with threads provided on the housing adjacent its open end so as to form a second releasable seal.

Abstract: A hollow stopper for dispensing fluid from a bottle having a neck and a top lip is provided. The stopper comprises a top wall having a laterally extending, downwardly open, spout-like protrusion. The top wall has a continuous, annular, uninterrupted undersurface for sealing engagement with the top lip of a bottle. An annular skirt depends from the top wall inwardly of said undersurface. The skirt is adapted to fit within the neck of a bottle and to move axially with respect thereto between a sealing position in which said undersurface is in sealing engagement with the bottle lip and a plurality of dispensing positions in which said undersurface is spaced from the bottle lip. The skirt includes an axial pouring slot extending from the top wall undersurface along one side of the skirt in alignment with the spout-like protrusion.
