Patent attributes
The metering device includes a metering container which can be fitted with screwing action on a standard bottle neck. The metering container has a funnel-shaped base, which is adjoined by a cylindrical lateral wall having, at the upper end, a cross-sectionally u-shaped collar, to which a cover surface can be applied in a form-fitting manner. At the top of the metering device is a pressure-exerting head with an encircling, detachable periphery. A puncturing mechanism having a two-part pressure-exerting pin can be actuated by the pressure-exerting head. The puncturing mechanism is fixed to the cover surface, prior to initial use, and is separated out of the cover surface by a cylindrical casing wall on the pressure-exerting head. The second part of the puncturing mechanism has a punching sleeve, which severs membranes which close the metering container, whereupon the contents of the metering container can be supplied into the bottle.
