Reclosable Food Tray and Tray Blank with Yang's Notch Cut as Fastening Mechanism; and Carrying Strap for Carrying Single or Multiple Food Trays

A blank adapted to be folded into a reclosable food tray having a fully constructed receptacle portion with a volumetric geometry which facilitates nesting of the receptacle portion of one food tray within the receptacle portion of another said food tray, said blank having a planar unitary construction, an interior and an exterior surface and a substantially square gross geometry, which comprises:

• a bottom panel of rectangular shape having a surface area defined by a first and second pair of opposing bottom fold lines;
• a first and second pair of opposing side panels hingedly connected to said bottom panel along said first and second pair of opposing bottom fold lines, said opposing panels defining four pair of adjacent side panels;
• four foldable gussets, each said foldable gusset being hingedly connected to each pair of adjacent side panels so that when said first and second opposing side panels are folded substantially upright with respect to said bottom panel, a receptacle portion with an access opening is formed, each said foldable gusset is folded and can be secured by Yang's notch cut and a short line cut to an opposing foldable gusset that has Yang's notch cut and a short line cut as well. Two Yang's notch cuts enable said gussets interlocked to each other. And each said side panel is disposed substantially upright at a first predetermined obtuse angle with respect to said bottom panel;
• a first pair of opposing closure panels, each hingedly connected to one of said first pair of opposing side panels and being dimensioned to close off a portion of said access opening when folded over said access opening and disposed substantially parallel to said bottom panel;
• a second pair of opposing closure panels, each hingedly connected to one of said second pair of opposing side panels and being dimensioned to close off said access opening when folded over said access opening and said first pair of opposing closure panels.

A blank adapted to be folded into a reclosable food tray having a receptacle portion with a volumetric geometry which facilitates nesting of the receptacle portion of one food tray within the receptacle portion of another said food tray, said blank having planar unitary construction and a substantially square gross geometry, which comprises:

• a bottom panel of rectangular shape having a surface area defined by first, second, third and fourth bottom fold lines;
• a first side panel contiguous with said first bottom fold line having a surface area defined by a first top fold line, a first left side fold line, a first right side fold line and said first bottom fold line, said first top fold line and said first bottom fold line being substantially parallel and said first left and right side fold lines diverging from said first bottom fold at a predetermined angle;
• a second side panel disposed opposite said first side panel and contiguous with said second bottom fold line, having a surface area defined by a second top fold line, a second left side fold line, a second right side fold line and said second bottom fold, said second top and bottom fold lines being substantially parallel and said second left and right side fold lines diverging from said second bottom fold line at said predetermined angle;
• a third side panel contiguous with said third bottom fold line having a surface area defined by a third top fold line, a third left side fold line, a third right side fold line and said third bottom fold, said third top and bottom fold lines being substantially parallel and said third left and right side fold lines diverging from said third bottom fold line at said predetermined angle;
• a fourth side panel disposed opposite said second side panel and contiguous with said fourth bottom fold line, having a surface area defined by a fourth top fold line, a fourth left side fold line, a fourth right side fold line and said fourth bottom fold line, said fourth top and bottom fold lines being substantially parallel and said fourth left and right side fold lines diverging from said fourth bottom fold line at said predetermined angle;
• a first foldable gusset with a Yang's notch cut and a short line cut created close to the tip of the edge being contiguous with said first and third side panels, and having a first corner fold line and a first corner edge;
• a second foldable gusset with a Yang's notch cut and short line cut created close to the tip of the edge being contiguous with said first and fourth side panels, and having a second corner fold line and a second corner edge;
• a third foldable gusset with a Yang's notch cut and short line cut created close to the tip of the edge being contiguous with said fourth and second side panels, and having a third corner fold line and a third corner edge;
• a fourth foldable gusset with a Yang's notch cut and a short line cut created close to the tip of the edge being contiguous with said second and third side panels, and having a fourth corner fold line and a fourth corner edge;
• a first closure panel with a Yang's notch cut on leading edge being contiguous with said first side panel;
• a second closure panel with a Yang's notch cut on leading edge being contiguous with said second side panel;
• a third closure panel with a Yang's notch cut on the leading edge being contiguous with said third side panel;
• a fourth closure panel with a Yang's notch cut on the leading edge being contiguous with said fourth side panel;
• and fastening means said Yang's notch cut formed in at least one opposing pair of said closure panels for selectively opening and closing said closure panels. With said Yang's notch cut on every single of said closure panel will increase tightness of fastening said food tray.
