Abstract
A foldable, waterproof case includes a first wall and a second wall coupled to the first wall. The first and second walls at least partially define a cavity within the case. A lid is coupled to the second wall and is configured to selectively cover the cavity. A hinge is disposed between the first wall and the second wall. The first wall is rotatable relative to the second wall between a first, expanded position of the case and a second, collapsed position of the case. In the first position, the cavity includes a first volume and in the second position, the cavity includes a second volume that is less than the first volume. The hinge provides a waterproof connection between the first and second walls in the first position and in the second position.
