Abstract
The metering device is adapted to be installed on the neck of a liquid product container so that, when the container is upended or otherwise oriented to supply the device with liquid, actuation of the device results in the release of a pre-sized dose of the product by gravity. Several different embodiments of the invention are disclosed, all but one of which adapt the device for filling its dosage accumulation chamber when the device is in a standby condition ready for dispensing. The other embodiment adapts the device to maintain its dosage accumulation chamber normally empty and to fill such chamber only upon temporary actuation.
