摘要

Pouring cap with built-in shutter, characterized essentially by the fact that it comprises a cap with hermetic adjustment means on the neck of a container, endowed at the bottom of a pipe, to whose cap is radially linked a sealing cap capable of closing the spout, articulated by means of external prolongations of the material itself with weakened transverse lines constituting a hinge, between which prolongations a strip is formed, also of the material itself and forming a single piece with the cap and the lid, separated from the mentioned extensions and constituting a bistable position spring that tends to maintain the lid in two stable positions: one of closing adapted to the spout and another of opening separated from it.
