A container for retaining articles includes a pliable sack and a closure attached to an opening of the sack. The closure includes a substantially flexible member having a pair of anchors and a substantially rigid member having a pair of pivotal seats. Each of the pivotal seats is adapted to receive a respective one of the anchors of the flexible member. The closure is positionable between a closed position in which the flexible member is substantially proximate to the rigid member and an opened position in which the flexible member is substantially separated from the rigid member. The closure may be configured to have a generally circular shape when in the opened position and a generally crescent shape when in the closed position. The seats may be configured to slidably receive the anchors to minimize complexity in the manufacturing process. Each of the rigid and flexible members preferably has a unitary construction to further reduce manufacturing costs. In addition, the sack preferably has a configuration that reduces the bunching up of material when in the closed position to allow the sack to seal completely. The container is configured so that a user may open and close the container with one finger. Further, the container remains opened or closed until manually operated to close or open, respectively, the container.
