发明名称 DUAL PURPOSE FOOD CONTAINER/BUILDING BLOCK ELEMENT
摘要 <p>A dual purpose sealable food container/building block element comprising an upper portion and a bottom portion, the upper portion being open, the upper portion and the bottom portion are provided with connecting members (5, 6), such that a plurality of the container/elements are connectable to one another by engaging the connecting members and sliding toward each other along the connecting members, for use of the container/elements as a toy after completing original use as a food container. To enable such large constructions to be firm and steady, the connecting members (5, 6) are of the slide type, engageable by insertion of rails (5) at the open ends of sockets (6) and sliding longitudinally into each other, perpendicular to the forces acting on assembled building blocks.</p>
