A blank made from foldable paperboard or similar sheet-like material adapted to be erected into a sealed carton, which, when opened, has a reclosable hinged top cover, comprising: a substantially rectangular sheet of said material having opposed top, bottom and lateral edges; three parallel fold lines spaced intermediate the two lateral edges of said sheet, said parallel fold lines defining four panels; said four panels including a bottom panel located at a first of said lateral edges of said sheet, an adjoining back panel, a top panel adjoining said back panel, and a front panel adjoining said top panel and located at the second lateral edge of said sheet from said bottom panel; closure flaps hingedly attached to the top and bottom edges of each of said panels; a perforated line extending from top to bottom across said front panel and said closure flaps attached to said front panel, said perforated line spaced from said second lateral edge of said sheet a predetermined distance, and said perforated line being formed in part in a U-shape to form an insertable reclosure tab; said perforated lines in said front panel closure flaps being oriented at predetermined angles in a direction away from said second lateral edge of said sheet from the ends of said perforated line in said front panel at the top and bottom edges thereof; and perforated lines in said back panel closure flaps aligned parallel to said perforated lines in said front panel closure flaps, extending from the ends of said back panel fold line at the top and bottom edges of said back panel; a glue flap hingedly attached to said bottom panel along said first lateral edge; said glue flap having a line-cut formed therein and spaced from said first lateral edge a length equal to said predetermined distance spacing of said perforated line in said front panel, said cut line adapted to receive said reclosure tab; and a fold line extending from top to bottom in said back panel adapted to become a hinge for rotating said reclosable top cover after said carton is opened.
Claim 2
Dependent Claim

A blank made from foldable paperboard or similar sheet-like material adapted to be erected into a sealed carton, which, when opened, has a reclosable hinged top cover, comprising: a substantially rectangular sheet of said material having opposed top, bottom and lateral edges; three parallel fold lines spaced intermediate the two lateral edges of said sheet, said parallel fold lines defining four panels; said four panels including a bottom panel located at a first of said lateral edges of said sheet, an adjoining back panel, a top panel adjoining said back panel, and a front panel adjoining said top panel and located at the second lateral edge of said sheet from said bottom panel; closure flaps hingedly attached to the top and bottom edges of each of said panels; a perforated line extending from top to bottom across said front panel and said closure flaps attached to said front panel, said perforated line spaced from said second lateral edge of said sheet a predetermined distance, and said perforated line being formed in part in a U-shape to form an insertable reclosure tab; said perforated lines in said front panel closure flaps being oriented at predetermined angles in a direction away from said second lateral edge of said sheet from the ends of said perforated line in said front panel at the top and bottom edges thereof; and perforated lines in said back panel closure flaps aligned parallel to said perforated lines in said front panel closure flaps, extending from the ends of said back panel fold line at the top and bottom edges of said back panel; a glue flap hingedly attached to said bottom panel along said first lateral edge; said glue flap having a line-cut formed therein and spaced from said first lateral edge a length equal to said predetermined distance spacing of said perforated line in said front panel, said cut line adapted to receive said reclosure tab; and a fold line extending from top to bottom in said back panel adapted to become a hinge for rotating said reclosable top cover after said carton is opened.
Claim 3
Dependent Claim
