A multi-piece snap together cap generally comprises a molded base cap and a covercap intended to be used on a flexible-walled container and in an inverted position. Neither the covercap nor the base cap require special orientation during the assembly process of the multi pieces. To assemble, the top open ring of the covercap is lowered onto the base cap. The ring is molded with a one-way negative snap-in void area that is formed with an undercut, insuring the top positive overlapping snap ring in locked in place after assembly. The top cap covercap piece is unique in its construction and combines several functional features. For instance, it is molded in the open position and connected to the top open snap ring with a living hinge, forming a single piece. When the lid is in the open position, the living hinge keeps it out of the way when product is dispensed. The top lid and snap ring also includes a second open/close friction snap ring, which keeps the top lid in a down position during storage and the internal product fresh. The top lid also provides an overhang tab so that the consumer may easily unsnap the lid with a fingertip.
