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.
Claims12
A container having an opening and a closure movable between a first position in which the opening is closed and a second position in which the opening is exposed, the closure comprising a closure flap located within the container and a pivot arm, the pivot arm having a first end secured to the closure flap and a second end having a weighted portion, the pivot arm being pivotally mounted within the container at a pivot point located between the first and second ends, wherein when the container is in a first position, the weighted portion acts to bias the closure flap to close the opening and when the container is rotated in a first direction to a second position, the weighted portion causes the pivot arm and the closure flap to rotate relative to the container in a second direction opposite to the first direction, thereby to bias the closure flap into the container and away from the opening in order to expose the opening.
