A container is disclosed having a plurality of interconnected panels forming sidewalls surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalls and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Each support flange is supported by a truss formed by a panel segment extending angularly from the support flange to a support panel biased against the sidewall to which the support flange is attached by a retaining flap extending from an inner sidewall layer. Locking tabs at the ends of each panel segment are received within recesses positioned in sidewall panels perpendicular to the support flanges. The container is transformed from a knockdown formed from a unitary blank.

Shipping containers that are convertible to display containers are disclosed. The containers comprise wrap around outer shells of the general type known as "Bliss" wraps, in combination with interior vertical support structures. The invention presents improved two- and three-piece container constructions, having improved side-to-end panel connections for improved tray strength upon conversion to a display configuration, as well as a variety of interior divider/support options. By advantageous adhesive application together with specialized opening structures such as tear strips, lines of weakness and/or hand holes, various different conversion configurations are provided.

Wraparound style packaging and shipping containers are provided, having structures configured for facilitating the conversion of the shipping containers into dispensing or all-around display containers. The shipping containers are preferably fabricated from an outer blank having a centrally positioned bottom wall, with front and rear walls emanating from front and rear edges of the bottom wall, respectively. Inner reinforcement panels may be provided for one or more of the end panels. The containers may incorporate lids formed from separate blanks, or lids formed from integral top panels of the wraparound blanks. Side flaps emanate from the bottom wall, the front and rear walls, and the top panels (if present), to provide at least partial coverage of the sides of the container. In several embodiments, separable structures are located in at least one of the front and rear walls, and/or the side flaps, to enable greater or lesser portions of the upper structure of the container to be removed, for permitting varying degrees of access to the interior of the container. An interior divider structure may be provided, for structural stacking support both during shipping and display modes.

A carton blank includes first and second spaced main panels and first and second side flaps abutting first and second side edges, respectively, of the first main panel. Third and fourth side flaps abut first and second side edges, respectively, of the second main panel and an intermediate panel is disposed between first ends of the first and second spaced main panels. A cover flap abuts a second end of the second main panel and a display flap includes first and second portions adjacent to one another wherein the first portion is joined to a second end of the first main panel by a score line and the second portion is joined to the second end of the first main panel by a perforated line collinear with the score line.
