Claim:
A carton for shipping and storing a quantity of cut sheets of paper, comprising: a carton base portion having a bottom wall, opposed upstanding front and back walls and opposed upstanding end walls, each joined along a bottom edge to a respective edge of the bottom wall, and an open top; a lid telescopically engaged over the open top, said lid having a top wall with depending end flanges, a depending back flange foldably connected to the lid top wall and attached to the carton back wall, and a depending front flange, said depending front flange comprising a tear strip having a longitudinal axis and being defined by two spaced apart parallel rows of successive straight inclined cut lines wherein the parallel rows of successive straight inclined cut lines being symmetrical with one another with respect to the longitudinal axis, the tear strip includes a tab which upon tearing moves in direction of convergence of the inclined cut lines, each of the inclined cut lines having an outer beginning end and an inner terminal end, whereby tearing propagates inwardly along a cut line from its outer beginning end to its inner terminal end and then outwardly to the beginning end of a successive cut line, said cut lines having a length (K) between the beginning and terminal ends, and the terminal end of one cut line being spaced from the beginning end of a succeeding cut line by a distance (D) as measured in a direction parallel to the longitudinal axis of the tear strip, wherein the ratio of D/K is from 1:1 to 4:1; said base portion front wall being unsecured to adjoining end walls and being pivotable about its bottom edge downwardly and away from the carton to an open position when the lid is moved upwardly away from said front wall, thereby exposing the cut paper at the top and one side to permit easy access to paper contained in the carton for rapid unloading of the paper from the carton; said front wall having inwardly turned tuck-in flaps on opposite ends thereof which tuck into the carton in contiguous, parallel, overlapping relationship with adjacent end walls when said front wall is in closed position; and said inwardly turned glue flaps being on opposite ends of said lid front flange and said lid back flange, said glue flaps on said lid front flange being attached to respective said lid end flanges, and said glue flaps on said lid back flange being free of attachment to said lid end flanges and wherein said glue flaps on said lid back flange are attached to respective said base portion end walls.
