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 household appliance includes a cabinet defining an interior, a tub located within the interior, and a basket located within the tub and having a loading opening confronting the tub opening. The appliance also includes a bulk dispenser with a dispensing opening, a first chamber in fluid communication with the dispensing opening, and a second chamber fluidly coupled to the first chamber.

Provided is a container, which comprises a container body and a cover and further comprises a variable-pressure component, a metering channel, a liquid extraction channel and an outflow channel. The head of the metering channel is in communication with the variable-pressure component, and the tail thereof is in communication with the outflow channel and the liquid extraction channel. A valve, which is opened when the variable-pressure component is pressurized and is closed when the variable-pressure component is depressurized, is provided between the metering channel and the outflow channel. A valve, which is opened when the variable-pressure component is depressurized and is closed when the variable-pressure component is pressurized, is provided between the metering channel and the liquid extraction channel or within the liquid extraction channel. The metering channel, the liquid extraction channel and the outflow channel are fixed to the cover.

Provided is a self-metering container, an initial positioning device thereof and an initial positioning method. The container comprises a container body, a variable pressure component, a metering channel and an outflow channel. When the variable pressure component is depressurized, contents in the container body enter the metering channel; and when the variable pressure component is pressurized, the contents in the metering channel flow outwards via the outflow channel. The container further comprises an initial positioning device. The initial positioning device comprises a backflow cavity, a backflow channel and a component capable of closing the backflow channel. The backflow cavity is in communication with the variable pressure component and the initial end of the metering channel. The initial end of the metering channel is higher than the bottom of the backflow cavity. The backflow channel is in communication with the bottom of the backflow cavity and the container body.

The invention relates to a metering system (1) for metering a metered medium comprising a frame housing unit (2) and a lever mounting unit (3) which his supported on the frame housing unit (2) comprising a lever mount (4). The invention further comprises a, preferably asymmetrical lever (30) which is supported rotatably by means of the lever mount (4) about a tilt axis (R) comprising a two-sided lever arm (31) extending substantially in a longitudinal direction (30L) of the lever (30), wherein one lever arm side (35), preferably the longer lever arm side (35), has a first actuator engagement point (36) close to the tilt axis and is in contact remotely from the tilt axis at an end portion (33) with an ejection element (13), preferably a ram (13), and wherein the other lever arm side (32), preferably the shorter lever arm side (32), has a second actuator engagement point (37) close to the tilt axis. The invention further comprises two actuators (50a, 50b), which, during operation, exert a tilting moment in opposite directions on the lever (30) at the first and second actuator engagement point (36, 37), wherein the actuators (50a, 50b) are placed obliquely to one another. Together, the lever mounting unit (3), the lever (30), and the two actuators (50a, 50b) thereby form a movement mechanism (4, 30, 50a, 50b), which is braced on the frame housing unit (2) by means of at least one spring element (21), preferably a disc spring set (21), wherein the spring element (21) is preferably arranged so that it braces the lever mounting unit (3) against the frame housing unit (2) via the lever (30) as well as via the two actuators (50a, 50b).
