A container that is easily openable, reclosable, reusable and storable in a lay-flat condition between uses. The container has a tuck-in closure. In this closure the cover panels are hingedly attached to triangular tuck-in end closure panels which fold over and then fold behind a flange on the upper edge of the container. The flange can be formed in the container at the time of its manufacture. The flange may also be a two-part flange provided by a two-piece container having separate body and cover elements. The body has a downwardly extending flange along its upper edge and the cover has an upwardly extending flange along its lower edge. The cover telescopes over the body and the cover flange locks behind the body flange. The closure panels then fold over and lock behind this flange.

A container comprising four side panels hingedly connected together, a flange extending around said side panels, the upper edge of said flange being aligned substantially with the upper edges of said side panels and the lower edge of said flange being below the upper edges of said side panels, said flange comprising a first and a second pair of opposed flanges, a top closure on said container, said top closure comprising cover panels hingedly connected to the upper edges of said first pair of opposed flanges, end closure panels hingedly attached to the upper edge of said second pair of opposed flanges and to said cover panels said end closure panels being divided by a pair of oblique score lines extending outwardly from the inner corners of said end closure panel, said oblique score lines dividing said end closure panel into a central section and two side sections, said end closure panels having U-shaped score lines, each of said U-shaped score lines being formed of three straight score line sections which meet at said oblique score lines, each of said three straight score line sections being in a separate central or side section, said three straight score line sections being oriented whereby said straight score line sections in said side sections will be congruent with said straight score line section in said central section when said end closure panel is folded along said oblique score lines, the distance between the upper edge of said flanges and one of said U-shaped score line sections in said central section being substantially equal to the width of said flange such that a portion of the end closure panels can be folded around the second opposed flanges to secure the cover panels in a closed position.
