• (a) base means of generally rectangular form;
• (b) wall catch means projecting upwardly from said base means;
• (c) a plurality of generally planar wall elements each forming upper and lower pocket means therein, said wall catch means of said base means being received within said lower pocket means to establish interconnected relation between said base means and said wall elements, said wall elements defining vertical external structural rib means, said upper and lower pocket means being defined within respective upper and lower ends of said external structural rib means;
• (d) top cover means of generally rectangular form;
• (e) wall catch means depending from said top cover and being received within said upper pocket means to establish interfitting relation between said top cover means and said wall elements;
• (f) shipping catch means depends from said top cover means;
• and
• (g) slot means is defined by said base means and receives said shipping catch means in the collapsed condition of said collapsible shipping container, said shipping catch means and said wall catch retain said wall elements within the collapsed shipping container.

A collapsible shipping container, comprising:

• (a) base means of generally rectangular form;
• (b) wall catch means projecting upwardly from said base means;
• (c) a plurality of generally planar wall elements each forming upper and lower pocket means therein, said wall catch means of said base means being received within said lower pocket means to establish interconnected relation between said base means and said wall elements, said base means defining spaced spill guard strips near the outer periphery thereof, said wall elements being received between said spill guard strips to form a substantial seal preventing entry of liquid and solid contaminants into said collapsible shipping container;
• (d) top cover means of generally rectangular form;
• and
• (e) wall catch means depending from said top cover and being received within said upper pocket means to establish interfitting relation between said top cover means and said wall elements.

A collapsible shipping container comprising:

• (a) base means of generally rectangular form, said base means defining a plurality of upstanding wall catches spaced along the outer edges thereof;
• (b) a cover structure of generally rectangular form having a plurality of wall catches depending therefrom;
• (c) side wall means forming upwardly and downwardlly directed pockets for receiving respective wall catches of said base means and said cover means;
• and
• (d) in the collapsed condition of said shipping container said wall means being stacked on said base means and said cover means being assembled to said base means, bringing said wall catches into force transmitting structurally interfitting relation, in said collapsed condition said shipping container being of significantly reduced height for conservation of storage and shipping space in the collapsed condition thereof.
