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.

A two-piece measured-dose dispensing closure (10) includes a cup-shaped measuring chamber (12) and a rotatable dispensing control lid (14). In use, the dispensing control lid is axially moved relative to the measuring chamber by rotation between a first closed position, a second intermediate dispensing position, and a third drain position.

A metering device for the metered withdrawal of free-flowing beverages and sauces from at least one storage container, including at least one chamber having an inlet for receiving the liquid from the storage container and an outlet for dispensing the metered liquid into a vessel, wherein the metering device has at least one temperature control device that heats or cools the metered liquid, wherein the metering device has two chambers that are arranged one above the other and are connected to one another in a fluid-conducting manner by a connecting channel, and wherein a vertically displaceable push rod extends along a longitudinal axis of the housing, through the outlet, the second chamber, the connecting channel, the first chamber, and the inlet, and, depending on the vertical position, the push rod closes the outlet and/or the connecting channel in a fluid-sealing manner and actuates the closure.

A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

A lid for a beverage container having a reservoir chamber for holding drink additive, a measurement chamber in fluid communication with the measurement chamber, and an upper chamber with a lower end in fluid communication with an upper end portion of the reservoir chamber. A plunger has an upper chamber seal, an upper seal and a lower seal, and an actuator moves the plunger between first, second and third plunger positions to dispense a measured drink additive in the measurement chamber into the container. The plunger has a central filler port to receive drink additive and an aperture in fluid communication with the reservoir chamber. The actuator includes a closure member closing the filler port and manually movable to move the plunger. A lock member is movable between locked and unlocked positions, and in the locked position prevents movement of the plunger from the first to the second plunger position.
