A can with an extensible pouring spout of plastic which is displaceable in a mouthpiece from a recessed position. The spout has a flange located on its upper end and is carried pendent in the can, to a pouring position projecting from the can in which it is kept by engagement of a securing part of the spout with a flat counterpiece on the mouthpiece. The securing part is formed by a mainly conical extension of the cylindrical side wall of the spout at the lower end of the spout, to which spout belongs a sealing plug of plastic for tight sealing of the upper open end of the spout. The sealing plug has a finger grip bendable thereinto and outside of circumferential projections or grooves for engagement with matching inside projections or circumferential grooves inside the spout. The can is particularly characterized in that dependable finger grip of the sealing plug branches off centrally from a central, membrane-like part of the bottom of the depression of the sealing plug, a plate part over one side of the depression, in order that the upper, outermost end of the finger grip may join firmly in the sealed position of the sealing plug in such a manner that the innermost end of the finger grip presses the central, membrane-like part of the bottom down, bulging like a spherical shell and pressing, thereby, by pushed-in pouring spout, a lower edge part projecting from the lower peripheral part of the sealing plug against the cylindrical part of the pouring spout, same pressing a circumferential bulge out for tight contact against the lower edge part of the mouthpiece of the can, the projecting lower edge part of the sealing plug extending downwards in front of a circumferential bead in the pouring spout, when a projecting flange rests on the upper flange of the spout, when this upper flange is resting on the mouthpiece of the can.
