Definitions

• the present invention relates to a built-in measuring cap. [0002] It also relates to a container equipped with such an integrated measuring cap to close its opening.
• Such caps with an integrated metering device thus limit the consumption of the product contained in the container to the single volume required to guarantee optimum efficiency of its functions.
• Such caps typically include a cap head comprising a thread to ensure their assembly with the neck of a bottle or a can, and a metering unit integral with the bottom wall of this head and forming a projection with respect to this back wall.
• Such a metering device typically consists of a hollow tubular body, open at its free end, to define, with the bottom wall of this head, a metering volume.
• This metering device is thus fully inserted into the internal volume of this bottle or this container, when the stopper closes it or this one.
• compositions which comprise at least one active principle intended for veterinary treatment and optionally for at least one excipient.
