The container comprising: a bottom plate; a plurality of inner walls extending substantially perpendicular to said bottom plate, forming a hollow, therebetween; a plurality of outer walls extending substantially perpendicular to the bottom plate and substantially parallel to, and spaced from, a corresponding one of the inner walls, the spacing forming a compartment between the inner and outer walls, wherein corresponding ones of the inner and outer walls are attached at selected points between the inner and outer walls to provide at least one substantially uninterrupted compartment, therebetween. The Lid may be of a transparent, semi-transparent or opaque material and may be of a material that operates as a cutting board. ## Claims ### Claim 1 A container comprising: a bottom plate; four inner walls extending substantially perpendicular to said bottom plate, forming a hollow therebetween, the intersection of two adjacent inner walls forming an inner corner; four outer walls extending substantially perpendicular to said bottom plate, said outer walls being substantially parallel to, and spaced a selected distance from said inner walls, the intersection of two adjacent outer walls forming an outer corner; a columnar member attaching each inner corner to a corresponding outer corner, each columnar member extending along the entire length of each of said inner corner and said corresponding outer corner to provide at least four substantially uninterrupted compartments; and a space formed within said bottom plate, extending substantially through said bottom plate, wherein access to said space is made through an opening in one of said outer walls. ### Claim 2 (depends on 1) The container according to claim 1, further comprising: a lip attached to a top edge of each of said outer walls, said top edge being opposite said bottom plate. ### Claim 3 (depends on 2) The container according to claim 2, further comprising: a lid having a top surface and a bottom surface, said lid having a plurality of outer edges extending from said top surface, said outer edges engaging said lip attached to each of said top edges of said outer walls. ### Claim 4 (depends on 3) The container according to claim 3, wherein said lid further comprises: a plurality of protrusions extending from said bottom surface of said lid substantially parallel to said outer edges, each of said protrusions formed to fit adjacent to said inner walls of said container. ### Claim 5 (depends on 4) The container according to claim 4, wherein said protrusions fit adjacent to said inner walls adjacent to said hollow. ### Claim 6 (depends on 4) The container according to claim 4, wherein said protrusions fit adjacent to said inner walls between corresponding inner and outer walls. ### Claim 7 (depends on 3) The container according to claim 3, wherein said lid further comprises: means for extracting air from said hollow. ### Claim 8 (depends on 1) The container according to claim 1, wherein said inner and outer walls extend from said bottom plate at an obtuse angle with respect to said bottom plate. ### Claim 9 (depends on 3) The container according to claim 3, wherein said lid further comprises: a writable region. ### Claim 10 (depends on 9) The container according to claim 9, wherein said region is of a material that is erasable. ### Claim 11 (depends on 1) The container according to claim 1, wherein said bottom plate is rectangular. ### Claim 12 (depends on 1) The container according to claim 1, wherein said bottom plate is square. ### Claim 13 A storage system, comprising: a container, comprising: a bottom plate; four inner walls extending substantially perpendicular to said bottom plate, forming a hollow therebetween, the intersection of two adjacent inner walls forming an inner corner; four outer walls extending substantially perpendicular to said bottom plate, said outer walls being substantially parallel to, and spaced a selected distance from said inner walls, the intersection of two adjacent outer walls forming an outer corner; a columnar member attaching each inner corner to a corresponding outer corner, each columnar member extending along the entire length of each of said inner corner and said corresponding outer corner to provide at least four substantially uninterrupted compartments; a space formed within said bottom plate, extending substantially through said bottom plate, wherein access to said space is made through an opening in one of said outer walls; and a lip attached to a top edge of each of said outer walls, said top edge being opposite said bottom plate; and a lid having a top surface and a bottom surface, said lid having a plurality of outer edges extending from said top surface, said outer edges engaging said lip attached to each of said top edges of said outer walls. ### Claim 14 (depends on 13) The system according to claim 13, wherein said lid further comprises: a plurality of protrusions extending from said bottom surface of said lid substantially parallel to said outer edges, each of said protrusions formed to fit adjacent to said inner walls of said container. ### Claim 15 (depends on 14) The system according to claim 14, wherein said protrusions fit adjacent to said inner walls adjacent to said hollow. ### Claim 16 (depends on 14) The system according to claim 14, wherein said protrusions fit adjacent to said inner walls between corresponding inner and outer walls.
