Abstract: The invention is directed to a dispenser of the type used for providing mured amounts of a paste, such as a toothpaste or shaving cream. A cylinder having a dispensing mouth but otherwise closed at the top is mounted for sliding movement within a casing in the bottom of which is a coiled spring and from which a piston rod extends upwardly toward the said mouth. A piston is slidably mounted on the piston rod with walls adjacent the inner wall of the cylinder, with a reed spring clip supporting the said piston. When the cylinder is pressed downwardly against the spring, the piston cannot move because of the gripping action of the reed spring clip and a predetermined amount of material is ejected from the mouth. Upon release of the cylinder, it moves upwardly under the force of the spring for a predetermined distance, and by action of the spring clip moves the piston upwardly. The parts are then in position for the next dispensing action.

Abstract: Apparatus and method for dispensing a gel containing seeds for planting. A container (11) has a piston (13) driven by a lead screw (14) for expressing the gel through outlet (12). A line (17) is wound around a control rotor (16) and a free end is secured at a fixed location (19). As container (11) is moved away from location (19), line (17) unwinds and rotates rotor (16) to express the gel at a rate related to the movement of the container (11), so that the operator does not have to match the dispensing rate to the rate of movement. In other arrangements the container moves towards the fixed location, or between two fixed locations. Other metering members may replace the line. Materials other than seeds in gel may be dispensed.

Abstract: A measuring and dispensing closure for containers of granular material employs a slide element slidable in and out of a container cap top. The slide element has a chute element positioned thereon defining a series of trap spaces into which granular material is passed from the container when the slide element is in its retracted position. When the container is turned upside down and the slide element is moved outwardly relative to the cap top, the chute chamber passes out from a discharge opening formed on the cap top to expose the trap spaces to atmosphere for dispensing the granular material. Communication between the interior of the container and the trap spaces during dispensing is prevented by a planar ledge portion formed on the cap top and underlying the space beneath the chute chamber member. The slide element is preferably formed of plastic molded material and also includes a biasing member to provide a return force against outward movement of the slide.
