A cover for a liquid container having a mechanism for selectively attaching the cover to the liquid receptacle, a valve centrally located upon the cover, the valve being adapted to either allow the flow of liquids or disallow the flow of liquids, the valve having a pair of outwardly extending hinged ears pivotal to urge the valve into the on position; a pair of spacing horns formed on the cover, each horn extending upwardly and coaxially from the top surface of the cover proximate the periphery ...

A container cap dispensing apparatus includes a cover member and a base member. The cover member is disposed over a portion of the base member, and the base member is secured to a container. The cover member is secured to either the base member or the container to allow the cover member to rotate relative to the container. The cover member and base member cooperate to drive a plug of the base member axially away from a dispensing opening defined in the cover member in order to permit the dischar...

An aseptic closure for containers of liquids comprising a main body provided with a threaded ring, which is designed to be associated with a neck of a container and from which there protrudes a tubular projection which is coupled to an upper closure. A step protrudes from the inside wall of the projection, proximate to the main body, and forms a passage hole which is controlled by a flow control element which is monolithic, by means of radial supporting bridges, with respect to the upper closure...

The present invention is directed to amphiphilic star polymers and their use as emulsion stabilizers in emulsion polymerization.

A neck element for collapsible tubes or the like wherein the neck is formed as by injection molding to maintain precise dimensional tolerances thereof in a configuration to receive a centerlock captive closure wherein the neck central plug is suspended by circumferentially spaced radial webs within a hollow neck body thereby to define a plurality of precisely formed dispensing apertures between the tubular member and the plug and terminating in orifices bounded by a sheared planar upper terminal...

A blended polymer composition that comprises: (a) from about 10 weight percent to about 40 weight percent of an ethylene-vinyl acetate copolymer resin; and (b) from about 60 weight percent to about 90 weight percent of a linear ethylene copolymer resin; wherein said weight percents are based on the weight of said polymer composition. A blended polymer composition that comprises: (a) from about 10 weight percent to about 40 weight percent of an ethylene-vinyl acetate copolymer resin; (b) from abo...

A deformable plastic dispensing cap of the snap-on type wherein a retractable dome covers a dispensing cylinder which is in communication with the interior of the container or tube. The upper portion of the dome is provided with partable lips, which expose the cylinder when parted, for dispensing the contents of the container or tube. To retain the dome lips in the retracted position, the interior of the dome is provided with ribs having projections thereon for engaging bosses provided on the ou...

An improved dewaxing aid for solvent dewaxing process comprising a mixture of (A) an .alpha.-olefin polymer having an average molecular weight of from about 10,000 to 1,000,000 and a wide molecular weight distribution exceeding the range of from about 10,000 to 1,000,000 but falling within the range of from about 2,000 to 3,000,000 wherein the .alpha.-olefin polymer is a homopolymer made up of a C.sub.10 to C.sub.25 alpha-olefin monomer or is a copolymer made up of a monomer mixture comprising m...
