An inner flexible container is formed with integral sidewalls and a base. A flange is provided at the upper portion of the container and receives the upper portion of a sleeve of paperboard or cardboard that is dimensioned to slide over the inner flexible container. A snap fit closure is applied to the interleaved flexible container\s upper flange and outer sleeve and is held in place through the cooperation of interacting tongue and groove and bead and recess sets on the closure and container flange, as well as wedge rings and a locking lip on the flange and closure, respectively. The sleeved container is similar in appearance to conventional frozen juice concentrate containers yet functions in a far superior fashion.
