Abstract: The presently disclosed subject matter relates generally to a system and method of generating at least one disinfecting gas within a package through a photochemical reaction. More particularly, the presently disclosed subject matter is directed to a system and method for controlled release of a generated gas from a polymeric film or lamination through selection of a suitable combination of lighting conditions.

Abstract: A liquid flow-restriction device has a plurality of flow-restriction passages connected to a common outlet. Each flow-restriction passage has a magnetically operable valve having a valve member movable between an open position and a closed position. The valves are operated by a common actuating element selectively positionable with respect to the valve members to open the valves. The actuating element is a permanent magnet. The device is simple and allows easy selection of a flow rate to a dilution dispenser.

Abstract: A liquid flow restrictor in the supply line of an eductor or other dilution or dispensing device has a rotatably mounted disc with opposite faces and a plurality of apertures or holes, which provide different flow restrictions between the faces, and a pair of flow conduits sealingly engaging against the faces, whereby on rotation of the member the zones are selectively brought into communication with the conduits to provide a desired flow restriction.

Abstract: The dispensing apparatus dispenses material into a container (34) having at least one predetermined shape component (40a) which cooperates with the dispensing apparatus to control a dispensing operation. There is a vertically movable support (8) for the container having a first, lower position at which the container is brought into a mounted position on the support and a second, higher position, and actuating means (24a,30) arranged for mechanical engagement with the container during lifting of the container on the support. The actuating device cooperates with the predetermined shape component or components of the container to determine, in dependence on the shape of the shape component the liquid or liquids to be dispensed into the container, and/or the quantity of a liquid to be dispensed into the container. The actuating device (24a,30) lifts cylinders (22,24) to dispense the liquid.

Abstract: A container for dispersing liquid through a dispenser is described. The container has a resealable outlet which has an outlet passageway in a tube and a stop wedged in the passageway to seal the liquid in the container. The passageway is accessible beneath the stop by a dispenser peg for insertion in the tube to push the stop inward toward the interior of the container. A means for containing the stop is adjacent the passageway inlet. The stop reseals the passageway by covering the passageway inlet after a dispenser peg is removed from the passageway.

Abstract: A manually operated dispenser for dispensing single shots of liquid with a built-in extended delay between each manually dispensed shot is described. The dispenser contains a manually operated pump for withdrawing a single shot of liquid from the reservoir of liquid, an outlet through which the pump dispenses the single shot and a reciprocal piston and cylinder assembly on the pump. The piston is ready to dispense the single shot of liquid into the outlet when in a retracted position. A plunger which is biased to move away from the piston manually moves the piston to dispense the shot. A detent is provided for locking the plunger in an outward position. A piston spring is loaded in a manner such that when the piston is moved to a retracted position the detent is disengaged and the relative movement of the piston from the extended position to the retracted position defines a built in extended delay between dispensed shots of liquid.

Abstract: A dispenser is described having a support for the container to be filled, a source of liquid and a switch controlling the flow of liquid into the container. The container is supported by a support which urges the container up or down. The switch is operated by the container such that when the container is empty it urges against a resilient mechanism which activates the switch. When the container is filled its weight overcomes the resilient mechanism.

Abstract: A foam limiting element for a dispenser for liquids is provided. The element comprises a three-dimensional mesh of a multiplicity of the fibers which are connected together to create a multiplicity of irregular liquid paths through the spaces between the fibers, the element having a three-dimensional configuration to fit within a dispensing head of a dispenser. A dispenser for liquids has a dispenser head with a discharge channel in which a foam limiting element is positioned. The discharge channel has means for retaining the element in place whereby all liquid flows through the element before being dispensed. The discharge channel has a wall structure which precludes introduction of air into the liquid to be dispensed.
