Abstract: The comestible fluid dispensing system of the present invention preferably employs a pump or valve operable to control movement of comestible fluid from a comestible fluid source to a tap provided with a draw-back valve. The draw-back valve is preferably capable of drawing comestible fluid in an upstream direction in the tap during closure of the draw-back valve. Preferably, suction generated by closure of the draw-back valve is employed for one or more purposes including: to remove comestible fluid dangling from the tap, to draw comestible fluid into the tap away from view and from exposure to the environment, to reduce comestible fluid buildup on and near the tap outlet, to enclose or at least partially enclose comestible fluid downstream of the draw-back valve, and to operate a downstream cutoff valve in the tap. A damper is employed in some embodiments to control valve movement.

Abstract: The inventive closure includes an annular part, to which a lid is joined by a hinge, and a the spout that is pushed inside the annular part. When pushing the spout into the annular part, the edge of the spout abuts against segments and is thus brought into the optimal drop-preventing shape.

Abstract: A tool designed to efficiently apply sealant to tile grout—it is a plastic, round bottle (4), with ounce indicator lines marked on the exterior (8); and a plastic nozzle (10) that tightly screws onto the bottle, via embedded threads inside the top of the bottle (16) and inside the base of the nozzle (18). Cellulose sponge (6 and 12) is fitted tightly inside the bottle (4) is fitted tightly inside the bottle (4) and nozzle (10); which controls the amount of sealant flow so that there is minimal dripping or waste of sealant. The applicator holds approximately 5 to 6 ounces of liquid grout sealant. The tip of the nozzle is marked (14) and gradated (14) so it can be cut with a razor to match the flow of sealant to the width of the grout. The application of sealant is controlled by gently applying pressure to the flexible bottle (4) and moving the tip at a 45 degree angle along the line of grout to be sealed.

Abstract: The invention relates to a dispenser for foamable liquids which has been improved with regard to the aspects of hygiene and reliability. According to the method, in addition to the pneumatic and hydraulic parts of the dispenser having a configuration which is to a great extent isolated from the external atmosphere, said dispenser has an air chamber (82) which subjects a nozzle/expansion body (74) first to an excess pressure and then to a negative pressure during the return stroke (HB) of an air piston (42) via a lateral bore (89). As a result, the outlet (80) is first cleared and any remaining foam in the nozzle/expansion body (74) is subsequently removed by suction and coagulated into soap solution. During the next working stroke, this minimal quantity of soap-solution is foamed again and expelled.

Abstract: A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.

A metering valve is used as a suck-back system to retrieve the remaining fluid in the main tube and prevent residue from occurring.

Abstract: A non-drip device or drip prevention apparatus eliminates all liquid dripping. The device includes a body with an orifice wherein the neck of a container may be inserted, a shoulder and a planar surface maintaining a joint in a recess. When the non-drip device is attached by interlocking, the planar surface acts as end of travel stop indicating that the attachment is completed. An angle associated with a quarter circle facilitates liquid reinsertion into the bottle. A diameter of the device enables the liquid to flow rapidly when poured and a ridge interrupts the liquid flow after it has been served. An overlap is provided for publicity or a print. The non-drip device is designed to eliminate dripping, for example, when wine is poured from a bottle.

Abstract: A valve assembly, for use in connection with the dispensing of hot melt adhesive material, comprises a snuffback valve member and a diversion flow valve member. The snuffback valve and diversion flow valve members are integrally connected together and are movable in opposite modes with respect to their valve seats such that when the snuffback valve member is seated upon its valve seat, the diversion flow valve member is unseated with respect to its valve seat, and vice versa.

Abstract: A fixed-nozzle dispenser pump suitable for large doses has a downwardly-directed nozzle tip (32) and an outlet valve arrangement (4) in a nozzle (3). A blocking element, such as a ball (41), of the outlet valve arrangement (4) is biased back along a close-fitting tubular draw path (43) in the valve after dispensing, so as to draw product back out of the nozzle tip and prevent dripping. A further feature is a subdivision of the nozzle tip and a flexible flap valve (35) blocking a resulting passage segment in the nozzle. This facilitates clearance of another nozzle passage (36) by the reverse suction. A further feature is a membrane (24) across the front of the piston plunger, advanceable relative to a piston seal (231) by pressure of a plunger head (21). This helps accomomodate the returned fluid and enables a spot-dosing action.

Abstract: A clear plastic paint container including primary container and lid, both of which are threaded. The container is unique because of the spill resistant convex pour spout, liquid recovery drain trough, redundant sealing to preserve contents and recessed molded bottom hand grip for more effective handling. The no-waste, no-special tools, no-rust, no-label obliteration, corrosion resistant, and thermal resilient advantages are just some of the auxiliary features. These enhancements by far surpass the conventional wisdom of the container industry. The use of “PETE” (Polyethylene Terephthalate) plastic or equivalent transforms this container to an eye appealing and practical alternative. The opportunity to offer such an improvement by only slightly reducing contents. The paint industry must have a keen interest in this container, not only because of the growing demand for plastic containers but also the numerous advantages listed in the summary.

Abstract: A dispenser has a container for a liquid, a vent opening to allow air into the container, a valve to control the admission of air into the container, and a dispensing opening for the liquid to be dispensed therefrom. The dispenser is mounted with the dispensing opening at the bottom. When the valve is closed, a pressure differential is created that prevents the liquid in the container from flowing out. Upon opening of the vent valve, the pressure differential is reduced and dispensing can continue. Such a dispenser can be used to dispense fluids of varying viscosities and even nonporous solids. In one embodiment of the invention, an infrared radiation emitter and an infrared radiation detector are arranged in such a manner that, when a hand is placed below the dispenser, radiation from the emitter impinges on the hand and is reflected to the detector.

Abstract: This invention relates to an improved dosing assembly (valve/feed line/liquid collecting vessel) which permits nearly immediate response time to an actuator signal. Such an assembly is used for the controlled introduction of any liquid through a valve into a collecting vessel. In particular, the inventive assembly exhibits substantially no leakage from the feed line into the liquid collecting vessel when the valve is closed and an instantaneous introduction of the feed line liquid into the liquid collecting vessel upon opening of the valve, both when a liquid possessing a surface tension of about 50 dynes/cm2 is used as the measurement standard. This assembly is particularly and preferably suited for injecting colorants into reactants for the production of polyurethane slabstock foam and permits a substantial reduction in foam waste due to low colorations during an on/off cycle.
