Abstract 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.
A can comprising an extensible pouring spout of plastic, which is displaceable in a mouthpiece of the can between a recessed position, in which the spout hangs within the can from a flange located at its upper end and 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 being formed by a conical extension of the cylindrical side wall of the spout at the lower end of the spout, a sealing plug of plastic for tight sealing of the upper open end of the spout, the sealing plug having a finger grip bendable thereinto and external circumferential projections or groovesfor engagement with matching internal projections or grooves in the spout, characterized in that the bendable finger grip of the sealing plug extends centrally, from a central dome-shaped outwardly convex membrane-like part of the bottom of a recess of the sealing plug, a plate part extends over one side of the recess to hold the upper, outermost end of the finger grip downwardly bent in the retracted position of the spout and in the sealed position of the sealing plug in such a manner, that the innermost end of the finger grip presses the central, membranelike part of the bottom down, whereby a lower edge part projecting from the lower peripheral part of the sealing plug is forced against the cylindrical part of the pouring spout, and forms a circumferential bulge or bend in tight contact against the lower edge part of the mouthpiece of the can, the projecting lower edge part of the sealing plug extending downwardly beyond a circumferential bead in the pouring spout, when the upper flange of the plug rests on the upper flange of the spout, while said upper flange of the spout is resting on the mouthpiece of the can.

A can comprising an extensible pouring spout of plastic, which is displaceable in a mouthpiece of the can between a recessed position, in which the spout hangs within the can from a flange located at its upper end and 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 being formed by a conical extension of the cylindrical side wall of the spout at the lower end of the spout, a sealing plug of plastic for tight sealing of the upper open end of the spout, the sealing plug having a finger grip bendable thereinto and external circumferential projections or groovesfor engagement with matching internal projections or grooves in the spout, characterized in that the bendable finger grip of the sealing plug extends centrally, from a central dome-shaped outwardly convex membrane-like part of the bottom of a recess of the sealing plug, a plate part extends over one side of the recess to hold the upper, outermost end of the finger grip downwardly bent in the retracted position of the spout and in the sealed position of the sealing plug in such a manner, that the innermost end of the finger grip presses the central, membranelike part of the bottom down, whereby a lower edge part projecting from the lower peripheral part of the sealing plug is forced against the cylindrical part of the pouring spout, and forms a circumferential bulge or bend in tight contact against the lower edge part of the mouthpiece of the can, the projecting lower edge part of the sealing plug extending downwardly beyond a circumferential bead in the pouring spout, when the upper flange of the plug rests on the upper flange of the spout, while said upper flange of the spout is resting on the mouthpiece of the can.
