A blank configured to form a package, the blank comprising:
- a bottom panel,
- a rear wall panel foldably connected to a first longitudinally extending side of the bottom panel,
- a front wall panel foldably connected to a second longitudinally extending side of the bottom panel,
- two opposing end wall panels foldably connected to a respective one of two opposing transversally extending sides of the bottom panel,
- two opposing sets of top wall panels foldably connected to a respective one of the two end wall panels along transversally extending sides of the respective end wall panel, opposite the bottom panel,
- wherein each set of top wall panels comprises a first top wall panel and a second top wall panel foldably connected to each other and arranged one after the other as seen along a longitudinal direction,
- wherein each set of top wall panels is configured to form a double-walled top wall when the blank is erected to form the package,
- wherein the first top wall panel is connected to the end wall panel and is configured to form an upper surface of the double-walled top wall and the second top wall panel is connected to the first top wall panel and is configured to form an inside surface of the double-walled top wall,
- two rear sets of corner panels, each rear set of corner panels being located at a respective rear corner of the bottom panel and interconnecting a respective end of the rear wall panel with a respective end of the respective end wall panel,
- wherein each rear set of corner panels comprises an inclined fold line extending along a virtual line extending diagonally away from the respective rear corner of the bottom panel,
- wherein each rear set of corner panels is foldable along the inclined fold line relative to the rear wall panel, to the respective end wall panel and to each other about the inclined fold line into triangular flaps into an interior of the package and alongside the respective end wall panel as the blank is erected into the package,
- two rear locking flaps, each rear locking flap foldably connected to an outwardly facing longitudinally or transversally extending side of the respective rear set of corner panels and extending away from the respective rear set of corner panels such that the rear locking flap, as the blank is erected into the package, extends longitudinally inwardly from the respective end wall panel and such that each rear locking flap is positioned between the respective first and second top wall panel forming the double-walled top wall,
- two front set of corner panels, each front set of corner panels located at a respective front corner of the bottom panel and interconnecting a respective end of the front wall panel with a respective end of the respective end wall panel,
- wherein each front set of corner panels comprises an inclined fold line extending along a virtual line extending diagonally away from the respective front corner of the bottom panel,
- wherein each front set of corner panels is foldable along the inclined fold line relative to the front wall panel, to the respective end wall panel and to each other about the inclined fold line into triangular flaps into an interior of the package and alongside the respective end wall panel as the blank is erected into the package,
- two front locking flaps, each front locking flap being foldably connected to an outwardly facing longitudinally or transversally extending side of the respective front set of corner panels and extending away from the respective front set of corner panels such that the front locking flap, as the blank is erected into the package, extends longitudinally inwardly from the respective end wall panel and such that each front locking flap is positioned between the respective first and second top wall panel forming the double-walled top wall
- two front locking tongues formed on the front wall panel or formed on a front top wall panel foldably connected to the front wall panel-along a longitudinally extending side of the front wall panel, opposite the bottom panel,
- wherein the two front locking tongues extends transversally from the front wall panel and from a longitudinally extending side of the front wall panel being opposite the bottom panel such that each front locking tongue, as the blank is erected into the package, extends transversally inwardly from the front wall panel or wherein the two front locking tongues extends transversally from the front top panel and from a longitudinally extending side of the front top panel being opposite the front wall panel such that each front locking tongue, as the blank is erected into the package, extends transversally inwardly from the front top panel, and such that each front locking tongue is positioned between the respective first and second top wall panel forming the double-walled top wall,
- wherein respective second top wall panel comprises at least one locking tongue being positioned along a transversally extending side of the respective second top wall panel, opposite the first top wall panel, and extending away from the second top wall panel along the longitudinal direction, and
- wherein at least one locking recess is formed in the respective end wall panel or in a fold line between the respective end wall panel and the respective first top wall panel,
- wherein the at least one locking tongue on the respective second top wall panel is/are configured to be inserted into the respective locking recess when the first and second top wall panels are folded to form the double-walled top wall and thereby lock the double-walled top wall in the erected state.
