Improved leaktight assembly, for pouring-out and gradual metering, for receptacles which contain liquids for washing and treating clothing, and which principally comprises a metering cap and a pouring spout, the novelty consisting in the fact that the pouring spout consists in its upper part of a cap with zones of thickness weakening, and is specially intended for facilitating gripping, and of a perimeter ring arranged on the neck of the receptacle, acting as retainer for the pouring spout and which, as said perimeter ring has a smaller diameter than the outer band of the pouring spout, prevents extraction thereof by conventional means, thereby guaranteeing a perfectly sealed closure system. <IMAGE>
