An article may include a single piece of material, such as corrugated cardboard, with scores situated such that when folded along the scores a square or rectangular container is formed with first and second adjacent triangular subcontainers. The article may include locking tabs to join the first triangular subcontainer with slots in the second triangular container which results in a near square box. The insert subcontainers complete with 2 bottles are then placed in a box for shipping. The added protection and buffer zones provide additional protection in the event the carton receives a sudden impact such as being dropped.
