Abstract
An angleworm storage box comprised of a pair of rigid, integrally formed rectangular frame members which are right angled in cross-section and are connected by a set of corner struts, also right angled in cross-section, and having latch members extending outwardly from their ends which are thrust through apertures defined by elastic materials in the corner portions of the two frames, the frames and struts being molded of rigid plastic material and the portions adjacent the aperture-defining portions being relieved to cause the aperture-defining portions to be more elastic in order to permit the relatively large end portions of the latch elements to pass therethrough and thereafter latch thereagainst to create a rigid, simple and inexpensive box framework. Foot members carried at each corner of the bottom frame are so designed as to nest with the cover member for the box. Simple, unique but highly effective latch means is carried entirely by the cover for the box. Fiberboard end, bottom and side panels are pressed into place in snug fitting relation within the framework and a cover panel covers a central opening within the cover.
