Abstract
Abstract A container is fabricated from first and second sections, each of which includes a central sector and wing sectors connected on opposite sides thereof. Each of the sections is foldable into a U-shape and the two sections are interengageable with each other to form a parallelepiped structure enclosing a chamber. One or more of the wing sectors has hooks formed therein for interengagement with hooks on the center sector of the other of the sections for locking the sections together. The first and second sections are preferably identical separate parts which are interengageable.

Total Claims: 15
Claim 1
Independent Claim
211 words
A collapsible container comprising first and second sections each including hingeably connected, generally quadrilateral central and wing sectors with the wing sectors being connected on opposite sides of the central sector so that each central sector has two opposite free edge sides and two further sides connected to the associated wing sectors, the sectors of the first section corresponding at least substantially in size and shape to the sectors of the second section, the sections each being foldable into a U-shape and being interengageable in cross-wise relation with each other to form a parallelpiped structure enclosing a chamber, each wing sector having a side connected to the associated central sector and a free opposite parallel side with a free end, each wing sector further having two free lateral sides extending between the first two said sides thereof, and hook-shaped portions on said free ends of the wing sectors and on the free edge sides of the central sectors, the hook-shaped portions on the wing sectors being engaged with the hook-shaped portions of the central sectors to lock the sectors together, each central sector being provided with grooves extending along and adjacent the hook portions thereof for preventing inward movement of the free ends of the wing sectors of the other section.
