A dispenser has an outlet nozzle which is reversibly movable by rotation of a control cap from a first extended position, in which adhesives is dispensed as a series of fine spots, to a second retracted position in which adhesive is dispensed as a film using the flat upper surface of the control cap as a spreading tool. The base of the nozzle is joined to the walls of the dispenser by a flexible membrane. The control cap is provided with a centrally located hole, in the flat upper surface, through which the nozzle can protrude, and an internal coaxial sleeve which surrounds the nozzle. The latter is provided with a locating stud which cooperates with a screw groove in the inner surface of the sleeve so that manual rotation of the control cap causes the stud to travel along the groove, thereby causing the nozzle to move between the first and second positions.
A flow regulator for controlling the flow of material from a container is disclosed, wherein the container includes a container outlet through which the material freely flows when the container outlet is not closed. The flow regulator includes a material passageway having an inlet. The inlet of the material passageway is moved relative to the container between a first position where the inlet of the material passageway is not aligned with the container outlet to prevent the free flow of material between the container and the material passageway and a second position where the inlet of the material passageway is aligned with the container outlet to permit the flow of material between the container and the material passageway. The regulator also includes a regulating flap, configured to substantially cover the container outlet, coupled between the container outlet and the inlet of the material passageway. The regulating flap is moved between a closed position where the flow of material from the container outlet is prevented when the container outlet and the inlet of the material passageway are out of alignment and an open position where the flow of material from the container outlet is permitted when the container outlet and the inlet of the material passageway are substantially aligned. In use, movement of the material passageway relative to the regulating flap controls actuation of the regulating flap between an open and a closed position.
A flow regulator for controlling the flow of material from a container is disclosed, wherein the container includes a container outlet through which the material freely flows when the container outlet is not closed. The flow regulator is biased in a closed position, but is moveable to an open position to provide for material flow from the container. The flow regulator may be progressively moved to permit varying degrees of material flow as the opening in the container is progressively opened. The flow regulator provides both a closure to obstruct material flow and a seal to preserve the container contents from outside contamination or degradation. The flow regulator is disclosed in combination with a bulk bin container to form a novel dispensing mechanism.
The present invention includes a conduit assembly having a fitment adapted to be sealingly coupled to a container, a closure mechanism, and a conduit operably coupled to the closure mechanism. The fitment includes a fitment passage and the closure mechanism is movable between a sealed position engaging the fitment to seal the fitment passage and an open position. The conduit is coupled to the closure mechanism for movement between a stored position and an operative position wherein the conduit is moved from the stored position toward the operative position when the closure mechanism is moved into its open position.
