ABSTRACT:
A roll of material, e.g., toilet tissue, rests ready for use upon the middle portion of a swivel support. The roll can be manually placed in optimum position through lateral apertures. When the roll is empty, a front flap of the swivel support, extending out beyond the front wall of the container, is pressed down, so that the swivel support swings upward and thereby ejects the empty roll through an opening in the container. As the front flap is pressed farther down, a locking lever, which previously prevented a spare roll from dropping, is pushed into a vertical position by a rear flap of the swivel support. When the front flap is released, the replacement roll slides onto the swivel support and presses the lower arm of the locking lever against the front wall of the container so that the upper arm of the lever regains its normal oblique position and prevents the next spare roll from dropping. Half-used rolls cannot be removed from the container, nor can a replacement roll drop into place until the empty roll has been ejected, thus ensuring trouble-free unrolling of the material.
