Abstract
A beaded-top twist container is provided with an inner layer and an outer layer, the outer layer being concentric with the inner layer. The inner layer is joined to the outer layer at the top and bottom edges by a bead. At least one rotatable segment is formed from the outer layer by separating the outer layer into at least three segments, the separations being formed by scoring through the outer layer without destroying the integrity of the inner layer. At least one rotatable segment is formed adjacent to a top or bottom bead by forming a separation adjacent the bead between the inner and outer layers.
