Spill and contaminant resistant dispensers and measuring cap devices and methods for measuring and dispensing a desired amount of a bulk particulate, powdery, granular or viscous liquid substance from a storage container through a cap or a dispenser are provided. A dispenser and measuring cap is attached to a storage container or comprises an integral storage container. The dispenser and measuring cap has one or more measuring chamber ducts, each having a different predetermined volume. The measuring chamber ducts are selectively and separately operationally aligned with an internal funnel stem and a dispensing spout. A selected measuring chamber duct is filled with the substance by inverting the cap and attached container. A measured amount of the substance is captured and dispensed, and the unused portion of the substance retained in the storage container without exposure to outside contaminants or implements, by rotating the duct into operational alignment with the spout.

An apparatus (1) for continuous gravimetric metering of pourable material comprises a housing (2) comprising a first and a second spaced wall (5,6), a charging port (7) through the first wall (5), and a discharging port (8) through the first wall (5) displaced from the charging port (7) and a primary air port (10) with a primary outlet opening (9) through the second wall (6) opposite to the discharging port (8). In the second wall (6) a secondary air port (12) is provided with a secondary outlet opening (11) having a substantially smaller outlet area than the primary outlet opening (9) and being displaced from the primary outlet opening in opposite direction to the rotational direction of the rotor (3) and being arranged opposite to the discharging port (8), and where the primary and secondary air ports (10,12) are connected to a compressed air supply.

A dispenser includes a main body having a discharge opening, an open interior configured to receive a supply of granulated product and a discharge spout for dispensing the granulated product therefrom. A loading and dispensing member is constructed with a plurality of spaced apart receiving cavities formed therein, and is movably mounted within the main body. A portion control container receiving the granulated product and defining a first portion control volume is received and removably retained in each of the plurality of retaining cavities. Each entire portion control container is removable from one of the receiving cavities and is replaceable with a different portion control container defining a second portion volume which is different that the first portion volume. An agitator is positioned within the main body, and is configured for separate engagement with each of the portion control containers to agitate the granulated product received in each of the portion control containers during movement of the loading and dispensing member.

A multi-stage rationed feeder for ornamental fish, comprising a container, a container cover assembly and a measuring cup assembly. A falling-material receiving cover of the container cover assembly is adapted to a container cover, and a buckle position is buckled into a container cover snapping slot, such that the falling-material receiving cover is rotatably mounted and connected to the container cover. The measuring cup assembly comprises a measuring cup and a blocking slice. One end of the blocking slice is provided with a sleeve hole for sheathing a blocking slice pin. A pin groove is adapted to a falling-material receiving cover pin snapped into the pin groove such that the measuring cup assembly is removably mounted and connected to the container cover assembly from below.

A powder supply apparatus includes a measuring shaft having a recess to be filled with powder, and a powder filling mechanism for filling the recess of the measuring shaft with the powder. The powder supply apparatus includes a rotary cylinder for sliding the measuring shaft along an axis of the measuring shaft, and a distal-end cover plate of a cylinder where the powder in the recess is leveled off by a slide of the measuring shaft. The rotary cylinder directs the recess downward by rotating the measuring shaft about the axis of the measuring shaft and supplies the leveled powder in the recess downward from the recess to a lifting plate at a predetermined position by dropping the powder.

The dispenser disclosed herein serves a single serving of a powdered nutrient contained within a container having multi-servings of the powdered nutrient. The dispenser has a metering device that operates as a ball valve or guillotine to dispense a single serving of the powdered nutrient into a water container. The dispenser also has a support surface that can be lowered and raised back up in order to fit a water container under the metering device and a distal tip of the metering device into a mouth of the water container so that no powdered nutrient spills out of the water container during transfer of the powdered nutrient from the metering device to the water container.
