A variable rate air metering system is provided. The system includes seed meter cartridges, each having a housing, a meter wheel, and a variable speed electric motor operatively connected to the seed meter cartridge. The seed meter cartridges provide flowable material to distribution manifolds, which are configured to distribute flowable material to multiple row outputs for deposition into a field. A control system is configured to control operation of the distribution manifolds for enabling/disabling dispersement of flowable material to row units. The control system is also configured to adjust the dispersement rate of flowable material by the seed meter cartridges in association with the opening/disabling the dispersement of flowable material to row outputs.

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.

A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed.

The present disclosure provides a dosing cap. In an embodiment, the dosing cap includes (A) a collar member having an annular skirt depending from a base. An inner surface of the annular skirt has a securing member for securing the collar member to a neck of a container. The base includes (i) at least one opening with a one-way valve permitting fluid flow in a first direction, and (ii) an air channel with a one-way valve permitting fluid flow in a second direction. The dosing cap includes (B) a cap member having an annular sidewall extending from a dispensing element. An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of the first sidewall. The dosing cap includes (C) a metering chamber formed by an enclosed volume between the cap member and the base. The dosing cap includes (D) the dispensing element permitting flow of a fluid from the metering chamber.

A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed. The valve may be a rotating valve including first and second valve parts which may form a divider of the dispenser that separates the measurement chamber from the storage container.

A fluid dispenser for measuring and dispensing fluid from a container includes a housing having a measurement chamber that defines a volume for receiving a predefined quantity of the fluid, a fluid flow passage having an inlet configured to be in fluid communication with the fluid in the container, and an outlet in fluid communication with the measurement chamber, such that the fluid flow passage permits fluid flow between the container and the measurement chamber. A valve member is provided that is movable in the flow passage to open the flow passage to permit fluid flow from the container to the measurement chamber to thereby allow the volume of the measurement chamber to fill with the predefined quantity of fluid; and to close the flow passage to restrict fluid flow from the container to the measurement chamber, and to isolate the predefined quantity of fluid to the measurement chamber.

A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed.

A dosing apparatus suitable for dispensing a dose of liquid from a resilient squeezable container including a cap, suitable for attachment to the container, the cap comprising an expulsion channel for the expulsion of liquid; a dosage chamber attached to the cap, the dosage chamber comprising side walls; at least one inlet opening in the side walls proximal to the cap; a pressure chamber located underneath the dosage chamber; a valve provided at the end of the pressure chamber distal to the dosage chamber, the valve being movable from an open position, allowing liquid to flow through one or more discharge openings, and a closed position where the valve closes each discharge opening, the valve incorporating at least one aperture; and a plunger provided in the dosage chamber, and movable relative to the dosage chamber so as to advance upon squeezing of the container, up to a blocking position.

The dosing cap includes (C) a metering chamber formed by an enclosed volume between the cap member and the base. The dosing cap includes (D) the dispensing element permitting flow of a fluid from the metering chamber.

Provided are a measuring mechanism for measuring a predetermined fixed amount or an arbitrary amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism. A measuring mechanism is provided that includes a base and a head defining a measurement space between the base and itself, the base and the head configured to be capable of changing the volume of the measurement space in response to a predetermined operation of the head including a measurement operation for increasing the volume of the measurement space and a discharge operation for reducing the volume of the measurement space. The base includes a first passageway for allowing the composition to flow from the outside into the measurement space, and a first check valve located on the first passageway. The first check valve of the base increases its sealability if there is a positive pressure in the measurement space.
