A volumetrically variable measuring dispenser cap comprising three primary components; an adaptor section attachable to a container having an inlet port, a volume selection ring rotatably mounted on the adaptor and having a closure plate of a size sufficient to cover the inlet port on the adaptor when appropriately rotated, and having a movable wall extending upward from the closure plate and finally, a rotatable chamber captively mounted to the volume selection ring having an inner cavity and a cover cap to close off the inner cavity. The device operates by movement of the selection ring so as to rotate the movable wall to a position within the inner cavity. The container to which the dispenser is attached is then inverted such that the material within the container falls through the inlet port in the adaptor, through the selection ring, and into the defined volumetric inner cavity. Once an amount has been thus directed into the inner cavity, the selection ring and the rotatable chamber are then rotated so as to seal off the inlet port of the adaptor. The container to which the dispenser is attached is then turned upright with the material within the inner cavity held between the adaptor section and the cover cap. To dispense the material, the cap to the cover section is flipped open, exposing the inner cavity and permitting the user to dispense the measured amount.

A dispensing device is provided herein for dispensing a selected amount of material from a container. The device includes a central disc which rotates to deliver a desired amount of material according to a pre-set adjustment. Total emptying of the container is assured due to the conically shaped hub member and the arcuate interior walls of the dispensing device.

A device for dispensing an exact, selected quantity of loose dry material, with this device comprising a multi-compartmented member rotatable about a substantially vertically-disposed axis toward and away from a reference location. The compartments of this member are of a specific, uniform configuration and spaced symmetrically about the substantially vertical axis. The multi-compartmented member is disposed between upper and lower generally planar partitions, with an aperture of approximately the same configuration as the compartments of the rotatable member located in each of the partitions. Importantly, one aperture is located in an offset relationship with respect to the other. Dry material to be dispensed is located above the upper partition, with such dry material dropping under the influence of gravity through its aperture into one or more of the compartments of the member as this member is rotated about its axis away from the reference location. As a result of this, one or more of the compartments of the member become filled with dry material, with the number of compartments filled being determined by the extent of rotation of the member away from the reference location. The material in the compartments thereafter drops downward through the aperture in the lower partition during rotation of the member back to the reference location. This novel measuring and dispensing device can be utilized as an integral part of a canister in which dry material is stored.

A dispenser having a base with a multiple of different sized perforated configurations which may be punched out and a groove for receiving a retaining tongue and a dispensing disk having an opening large enough to accommodate the largest perforation punch out. There is a cap having a slot for receiving the lever portion of the dispensing disk and a tongue for communication with the groove of the base, retaining the cap securely onto the base so that when the lever is moved back and forth a single unit is dispensed.

A metering and dispensing closure for a container wherein two rotatable disks rotate in conjunction with a stationary cap member to afford accurate measuring of a powder material and dispensing of it. The disks and the container cap afford a consistent measuring of the powder material, as well as provide a variety of drive members which can be utilized with the dispensing closure.
