A flexible plastic container 1 comprises a pouring adaptor 2 which is manufactured in a single piece with the closure device 3, in order to form a rigid plastic element.
<??>Before withdrawing any of the contents of the package, the closure device 3 is unscrewed, which device is connected to the pouring adaptor 2 solely by the area of wall 4 with reduced thickness. Using a tubular portion 6, which is of a single piece with the closure device 3 and is used as a closure stopper, it is possible to re-stop the pouring orifice as often as desired.
