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.

MEASURED FLUID DISPENSER
20210063220 · 2021-03-04 ·

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.

VARIABLE RATE AIR METERING SYSTEM
20210072063 · 2021-03-11 ·

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.

Storage container with measuring spout
10890476 · 2021-01-12 ·

A storage container (1) having a pour spout (7) that doubles as a measuring cup for dispensing a set amount of contents from the storage container. A user may manipulate the storage container to force the contents into the spout. The contents are prevented from falling or spilling out of the spout while the storage container is in an upright position.

Trash receptacle granule dispenser

A dispenser for dispensing scented granules into a trash receptacle includes an enclosure having an open top end, a bottom end, and a peripheral wall. The enclosure is fixed against a bottom side of a lid to the trash receptacle with a riser tube traversing an aperture of the lid and an attachment ring. A portion control flange is fixed inside the enclosure proximate the bottom end thereof to segregate a predetermined portion of the scented granules when the enclosure is in a first upright orientation. A top end of the portion control flange is fixed with the peripheral wall which has a discharge aperture therethrough below the portion control flange. When the enclosure is placed in a second orientation inclined towards the discharge aperture, the segregated scented granules slide between the portion control flange and the enclosure to exist the discharge aperture into the trash receptacle.

Metering device for liquid supply with connector
10234317 · 2019-03-19 · ·

The dosing device consists, for example, of a closure, having a closure body (1) with sealing closing means (7), which can be placed in a sealing manner on the connector. The metering means of the closure consist of just two components. There is first, seated securely in the closure body (1), a hollow cup (4) having, on the bottom side of the cup (4), a window (12) arranged in its side wall. The second component is a cap-shaped metering piston (10) having, on the upper side of the cap, a projection (5) which extends in the axial direction. This metering piston (10) with projection (5) fits into the cup (4), wherein its projection (5) covers and closes the window (12). The metering piston (10) is able to move axially in the cup (4) and its projection (5) is able to pivot to a limited degree toward the outer side of the window (12). In the pivoted-out state, it forms, together with the cup (4), an open valve which is otherwise closed.

LIQUID DOSING DEVICES

A dosing device is described, for dispensing doses of liquid from a container. It has an outlet passage with a front outlet tube (44) and a control chamber (2,29) positioned behind the front outlet tube. A flow path for dosed flow of liquid squeezed from the container leads in around the front of the control chamber (2,29) to the outlet tube (44), via flow openings (23). The control chamber (2) has control openings (28) to admit a restricted flow and time the fall of a blocking piston (3) to a blocking position where it blocks the outlet passage to terminate a dose. To improve uniformity of dosing, the outlet tube (44) has a tortuous flow-restricting formation (449) formed by a set of inward radial finger projections (49).

Measuring mechanism, and fixed-quantity dispensing container and fixed-quantity applicator including the same

A mechanism for measuring an amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism including a base and a head defining a measurement space therebetween. The base and the head are 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.
