1. A container having a closed bottom, an open mouth, and contiguous walls extending between said closed bottom and said open mouth, said walls having ribs extending between said closed bottom and said open mouth, said ribs formed with an elongated slot throughout a major portion of their length, said open mouth has a planar flange about the periphery, said flange extending outwardly beyond said ribs, said flange terminating with a vertical extension, said planar flange contains at least two opposed integral fasteners located approximately 180 degrees from each other about the periphery of said flange, said fasteners composed of a recess and an adjacent planar hinge portion of said flange, said hinge portion carrying a pin which forms a friction fit in said recess wherein a top is secured to said container, said top having a planar surface in contact with said planar flange of said container, said planar surface having at least two apertures located 180 degrees from each other about said planar surface, said apertures aligned with each of said recesses of said fasteners. 2. A container of claim 1 wherein said closed bottom is recessed and said ribs form supporting surfaces. 3. A container of claim 1 wherein said vertical extension is continuous about said periphery of said flange. 4. A container of claim 1 wherein said vertical extension is discontinuous about said periphery of said flange. 5. A container of claim 4 wherein a continuous raised shoulder is formed between said mouth and said planar flange. 6. A container of claim 1 wherein said friction fit is formed as a snap fit. 7. A container of claim 1 wherein said top is planar. 8. A container of claim 1 wherein said top is concave-convex and has a planar flange. 9. A container having a closed bottom, an open mouth, and contiguous walls extending between said closed bottom and said open mouth, said walls having ribs extending between said closed bottom and said open mouth, said ribs formed with an elongated slot throughout a major portion of their length wherein said ribs have a greater depth near said open mouth and a lessor depth near said closed bottom, said ribs having a sloped shoulder connecting said lesser depth and said greater depth, one end of said elongated slot located in said sloped shoulder. 10. A container of claim 1 wherein said ribs have a greater depth near said open mouth and a lesser depth near said closed bottom, said ribs having a sloped shoulder connecting said lesser depth and said greater depth, one end of said elongated slot located in said sloped shoulder. 11.
