A sealable square bottom container apparatus for use in storing, shipping and using various contents contained therewithin, said container apparatus preventing the inadvertent migration and release of oils, steam, fluids and fine powdered materials, among other types of contents, from within said container apparatus to the outside environment during said storage, shipping and use, said container apparatus comprising:
- bag means for containing said articles, said bag means including a front panel, a back panel, side panels and a bottom panel;
- each of said front, back and side panels having an interior surface and an exterior surface, top and bottom edges and first and second side edges;
- said side panels comprising at least first and second side panels interposed between and operably connecting said front and back panels, respectively, so as to form a contiguous tube about a longitudinal axis, said contiguous tube including a top end bounded by said top edges of said front, back and side panels, a bottom end and an interior region bounded by said interior surfaces of said front, back and side panels;
- each of said front, back and side panels further including front, back and side panel closure flap means for forming said bottom panel and having corresponding interior and exterior surfaces and side edges, said front, back and side panel closure flap means emanating downwardly from the respective bottom edges of each of said front, back and side panels respectively, to collectively form said bottom panel upon articulation and sealing of said respective panel closure flap means,
- each of said front, back and side panel closure flap means emanating from said respective ones of said front, back and side panels at front, back and side flap folds respectively interposed therebetween,
- said side panel closure flap means respectively forming a substantially rectangular first side bottom panel and a substantially rectangular second side bottom panel, opposite said first side bottom panel, as part of said bottom panel, upon articulation of said side panel closure flap means,
- said first side bottom panel emanating from said first side panel at a first of said side flap folds and said second bottom side panel emanating from said second side panel at a second of said side flap folds, each of said first and second side bottom panels, upon said articulation and folding at said respective side flap folds, being positioned independent of each other in a non-overlapping orientation;
- said front and back panel closure flap means respectively forming a front bottom panel and a back bottom panel opposite said front bottom panel upon articulation of said front and back panel closure flap means,
- said front bottom panel emanating from said front panel at said front flap fold and said back bottom panel emanating from said back panel at said back flap fold, with said front and back bottom panels, upon said articulation and folding at said respective front and back flap folds, being positioned in overlapping orientation
- sealable adhesive material operably positioned on the interior and exterior surfaces of at least one of said front, back and side panel closure flap means, prior to articulation, for operable, overlapped sealing of said front and back bottom panels over one another and over said first and second side bottom panels, upon articulation of said closure flap means to seal same;
- said sealable adhesive material being positioned on at least two of said front, back and side panel closure flap means to create, upon said sealing, a substantially closed, positively locked, continuous periphery of sealed attachment among said front, back and side panel closure flap means,
- said sealable adhesive material on said front, back and side panel closure flap means, and, in turn, said front, back and side bottom panels, respectively formed thereby, imparting to said continuous periphery of sealed attachment, a substantially rectangular shape within said formed bottom panel, having a region devoid of said adhesive material therewithin said periphery, to thereby maximize the region of sealed attachment against which the weight of said contents may be distributed within said interior region;
- said substantially closed, positively locked, continuously sealed periphery along said bottom panel forming a sift-proof bottom panel closure that is substantially restrictive to the migration of oils, steam, fluids and finely powdered materials.
