ABSTRACT:
A closure for receptacles is provided which can be produced in one piece by injection molding or the like from plastic material and has a rigid pouring spout linked to the base of the cap-shaped, substantially rigid closure body which is disposed in swivelling fashion between a locked position folded down in the plane of the base and a position being approximately vertical thereto and is connected to the cap body via a membrane-like flexible wall portion. The pouring spout has at its circumference one or several bar projections, over which a bar projection engages which can be elastically bent outwards in the locked position to secure the pouring spout in this position.
