A flexible disposable spout removably mounted to the inwardly extending flanges found in certain types of cans, particularly paint cans, to ensure that its contents are properly poured out and no contact is made with the can itself. The spout has a cylindrical or frustoconical shape with two ends. At least one of the ends has two parallel and peripherally extending ridge members that are kept at a predetermined spaced apart relationship with respect to each other to cooperatively engage with the inwardly extending flange defining the can opening. The other end may be designed to also accept the same type of inward flange for an opening of a different size typically associated with a can of a different capacity or the same capacity with different opening dimensions. Thus the spout's cylindrical portion has a frustoconical shape. The peripheral ridge member farthest from the end is larger in longitudinal height than the one adjacent to the end so that it acts as a stopper against the inwardly extending flange when spout is pushed through the can's opening. The separation between the ridge members of the distal end, not engaged to the can, block the running of any residual paint down the spout.
A spout for cans that include an inwardly extending flange and a peripheral channel extending parallel and outwardly spaced apart from said flange, said spout comprising a cylindrical body having first and second ends, said first end including first and second peripheral ridge members extending at a parallel and spaced apart relationship with respect to each other with a first predetermined distance in between to lockingly receive said flange thereby removably mounting said spout to said can wherein said first peripheral ridge member is the closest to said first end, and said second peripheral ridge member having a larger longitudinal height than the longitudinal height of said first peripheral ridge member so that when said first end is pushed through said can opening said inwardly extending flange cammingly deflects said first peripheral ridge member and once overcome said flange is removably lodged between said first and second peripheral ridge members and stopped by said second peripheral ridge member wherein said second end includes third and fourth peripheral ridge members extending at a parallel and spaced apart relationship with respect to each other with a second predetermined distance in between to lockingly receive said inner ridge thereby removably mounting said spout to said can, said third peripheral ridge member being closer to said second end than said fourth peripheral member.
A spout for cans that include an inwardly extending flange and a peripheral channel extending parallel and outwardly spaced apart from said flange, said spout comprising a frustoconical body having first and second ends with different diameters said first end including fast and second peripheral ridge members extending at a parallel and spaced apart relationship with respect to each other with a first predetermined distance in between to lockingly receive said flange thereby removably mounting said spout to said can, and wherein said first peripheral ridge member is the closest to said first end, and said second peripheral ridge member having a larger longitudinal height than the longitudinal height of said first peripheral ridge member so that when said first end is pushed through said can opening said inwardly extending flange cammingly deflects said first peripheral ridge member and once overcome said flange is removably lodged between said first and second peripheral ridge members and stopped by said second peripheral ridge member and wherein said second end includes third and fourth peripheral ridge members extending at a parallel and spaced apart relationship with respect to each other with a second predetermined distance in between to lockingly receive said inner ridge thereby removably mounting said spout to said can, said third peripheral ridge member being closer to said second end than said fourth peripheral member so that cans with openings of different dimensions can be engaged with each of said ends.
