Definitions

• the present invention relates to a metering device intended to be inserted into the neck of a bottle or similar container containing a liquid.
• Liquid metering devices are already known, engaged in the neck of a bottle, comprising two compartments, namely a first metering compartment filling with a predetermined volume of liquid during the inversion of the bottle from its normal vertical position. and a second reserve compartment communicating with the dosing compartment so as to receive the predetermined volume of liquid contained in the dosing compartment when the bottle is replaced in the normal vertical position.
• the reserve compartment also communicates with an outlet orifice of the metering device so as to pour out the dose of liquid contained in the reserve compartment when the bottle is turned over.
• Such a device is described for example in patent FR-1,047,119.
• This patent describes a dosing cap constituted by a tubular frame with a profiled upper part forming an external cap and a lower part closed by a sliding cap; an internal partition divides the reinforcement into two chambers, a filling chamber and a reserve chamber.
