ABSTRACT:
A container wherein a top member and a base member are formed as identical units, e.g., from a common mold, and have interactive shapes that permit the top to be laid upon the bottom in a nesting, closed configuration, and rotated relative to the bottom to one or more open configurations with at least three points of engagement whereby the size of the openings therebetween are varied in the different open positions and allow for movement of ambient air therebetween. The top cover and base, formed with identical common interfacing areas, can be subsequently modified, e.g., decorative or ornamental components can be added to the other, non-interfacing areas. Additionally, a handle could be added to the top cover. A pedestal could be added to the base. In a preferred embodiment, each member has a curvilinear outer periphery. During such rotation, there is a concomitant upward or vertical motion of the top member away from the base member caused by the camming interaction of the interfacing outer periphery curvilinear portions of the top and base members. The members are returned to the closed position by continuing further rotation in the same direction or by reversing the direction of rotation of the top member relative to the base member. The two members can be separated and then returned to nesting engagement, the outer peripheries engaging and guiding relative movement of the two members as they are returned to the nested configuration.
