Abstract
A container has an opening and an automatic closure. A closure flap is secured to a pivot arm, the other end of which has a weighted portion. The closure flap and pivot arm are located within the container. When the container is in a normal upright position, the weighted portion biases the closure flap into a closed position. When the container is rotated in a first direction, the weighted portion causes the pivot arm and closure flap to rotate in a second, opposite direction so that the opening is exposed.
