摘要

The device has parts designed to be introduced into a container (b) during or before closing of the container using a stopper. The parts are fixed at the stopper or the container. The parts are assembled to create variable volumes. A gauge (d) determines the parts to be inserted in the container. A modified clamp system (f) of the stopper is provided as a clamp on which a stop (f') flattens the stopper fitted with a seal during closure of the container. The parts are distinguished by a marking, a form, and a color according to the volumes.
