Abstract: A liquid dispenser (10) for a container of liquid, comprises a spout (12) and a liquid uptake structure (18) aligned to provide liquid to the spout from a container. The liquid uptake structure has first openings (20) radially distributed at the spout end, second openings radially distributed around the container end and a third opening centrally located at the container end. The liquid uptake structure provides an airflow path through the second openings and a principle liquid flow path separate from the airflow path through the third opening, thus separating the two flow paths and providing a smooth pour.
Abstract: The present invention relates to a screw-on interface for bottle spouts that secures a spout to a bottle in a manner such that wear and/or breakage of the bottle interface from standard usage is minimized. In an embodiment of the invention, the screw-on bottle interface incorporates a stainless steel plate in its threaded collar. This plate prevents damage to both the spout and the screw-on bottle interface when users over-tighten a screw-on bottle interface equipped bottle spout during installation of the spout onto a bottle.
Abstract: A dual tube container with one way valves comprises an outer tube and a cap, wherein, the tube head of the outer tube is provided with a base plate; the base plate is provided with a left through hole and a right through hole connecting the outer tube and the inner tube; a connector extends downwards from the right through hole, and the inner tube body in the outer tube body is connected to the connector to form the inner tube; a pair of one way valves are fixed in the tube head; an applicator with a orifice is inserted into the tube head; when the cap is put on to close the tube head, the pintle or elastic gasket in the cap sealing the orifice on the daub part of the applicator to prevent the leaking of liquid contents. It is provided with a pair of one way valves, and the inner tube is fixed in the outer tube; via the opening or closing of the pair of one way valves, the contents of the outer tube and the inner tube are permitted or forbidden to flow out.
Abstract: A replaceable auger assembly includes a body having at least one material inlet defined therein and an auger disposed within the body. The auger includes a helical portion disposed about a shaft portion and a positive shutoff mechanism. The positive shutoff mechanism is configured to selectively close the material inlet.

Abstract: A closure device (4) is used to seal an opening of a vessel (6), while providing access to the interior of the vessel. The closure device automatically releases gas and/or toxic vapor from the sealed vessel to protect the operator from harmful vapor without requiring the operator to manually actuate a valve or other mechanism prior to removing the vessel from the closure device. The closure device is constructed so the interior of the vessel can be pressurized while maintaining a pressure seal against the vessel opening, and the vessel can be cannulated without overpressurizing the vessel interior.
Abstract: A bottle closure for sealingly closing a bottle while providing access to the interior of the bottle, the bottle being of the type having a neck with external threads thereon, and a mouth at the top of the neck. The bottle closure including a generally cylindric stopper having a radially outwardly projecting flange, a radially inwardly tapering lip projecting axially outwardly from one end of the stopper for insertion into the bottle through the mouth for sealing the bottle and at least one passageway extending through the stopper. The stopper has ears which are axially spaced from the flange. The flange and ears retain a cap on the stopper but allow the cap to rotate with respect to the stopper so that the cap may be tightened on and loosened from the threads of the bottle without unsealing the stopper from the bottle.
Abstract: A manually deformable container utilizes air pressure resulting from squeezing the container to project a jet of liquid. Some of the pressurized air is ejected around the liquid jet to assist in atomization. A nozzle unit is supported on a transverse perforate plate preferably interposed between the container and a threaded closure member defining an air-discharge orifice around the end of the nozzle. Alignment of the nozzle with respect to the orifice is provided by either a lateral shiftability of the plate, a self-centering action of the plate in the container, or by a diaphragm deflection of the plate as the nozzle may tilt in finding its own way into the air orifice. An axial diaphragm deflection of the plate is used to provide a resilient seal of the liquid nozzle by tightening a screw cap against a projecting end of the nozzle, preferably followed by a sealing of the air orifice as the cap is further tightened.
