A container, movable between collapsed and expanded conditions, has a plurality of walls connected between bottom and top structures. A first wall of the plurality of walls includes first and second sections that connect together at a fold line about which the sections are rotatable between first wall collapsed and expanded conditions. The first section is connected to the bottom structure and the second section is connected to the top structure. The first wall is expandable by rotation of the first section relative to the second section in a first direction of rotation about the fold line from the first wall collapsed condition and into engagement with an abutment at the first wall expanded condition which arrests further rotation of the first section relative to the second section. The first wall is maintained in the first wall expanded condition by a load applied to the first wall.

A foldable container moveable between a stowed configuration and a deployed configuration defining an interior area for holding bulk material is provided. The container includes opposed side panels and a bottom flap extending from a bottom edge of each side panel. A tab member extends from a distal end of each bottom flap and a tab finger extends from each tab member so as to define a hook at a distal end of each bottom flap. The hooks are interconnected so as to hingedly connect the distal ends of the bottom flaps together, thereby causing the bottom flaps to rotate between their respective stowed and deployed configuration positions as the end panels are translated between their respective stowed and deployed configuration positions. Locking tabs extending from distal ends of end flaps extend into the interior area of the container to secure the container in the deployed configuration.

A blank used for making a container with insertable tabs is disclosed. The blank comprises a primary panel, a secondary panel, and an opening. The secondary panel is hingedly coupled to the primary panel. The secondary panel is hingedly coupled to a secondary flap. The primary panel is hingedly coupled to a primary flap. The primary flap is hingedly coupled to a tab. The tab extends towards the secondary flap. At least a portion of the tab lies within an aperture positioned between the primary flap and the secondary flap. The tab is configured to be inserted in the opening when the container is in a box configuration. Embodiments foster a container with insertable tabs that rapidly, easily, and conveniently transitions to a box configuration. Moreover, the container provides convenience and efficiency without compromising cost effectiveness and structural integrity.

Disclosed is a cartridge for medical and hospital waste, which comprises: a tubular body (1) provided with a base (3) and which is folded flat along the centre of the base (3) and along folding lines (12) on the tubular body, forming a flat body that can be stored easily; and a grid (2) made of sheets of card, which is disposed folded inside the tubular body (1) and which, when the cartridge is unfolded, opens to occupy the entire inside surface of the cartridge, defining cavities for receiving the medical waste. The base (3) can be formed from stiff card.

Containers that are capable of transitioning from a collapsed configuration to an uncollapsed configuration. The containers, when in a collapsed configuration, may have a relatively low profile. When in an uncollapsed configuration, the containers can function as receptacles for receiving solids or liquids. Some containers can be manufactured by folding a foldable sheet that includes a plurality of openings.

A collapsible and self-erecting polyhedron system is provided. The system includes a collapsible and self-erecting box. The box comprises cardboard and includes outer surfaces upon which images (e.g., photographic reproductions), graphics, and text are printed to provide a three-dimensional greeting card. The three-dimensional greeting card (the box) is collapsed and placed into an envelope, and upon being removed from the envelope, automatically self-erects providing a fun and exciting experience. Confetti also is included within the box that is ejected during the box self-erecting, thereby providing even more enjoyment.

A self-erecting packing case formed from a single board blank, the packing case comprising: first and second side walls and first and second end walls integrally connected together along respective parallel fold lines; a first-type base panel integrally connected to a bottom end of each of the first and second side walls along a respective fold line; and, a second-type base panel integrally connected to a bottom end of each of the first and second end walls along a respective fold line; wherein each first-type base panel is glued to an adjacent second-type base panel and comprises a fold line along an edge of where the first-type base panel is glued to the adjacent second-type base panel; and wherein each first-type base panel further comprises a lobed section integrally connected along a fold line, wherein the lobed sections of each first-type base panel are arranged to deflect and then interlock with each other when the packing case is erected from a collapsed condition, thereby to form the base of the packing case.

A container, movable between collapsed and expanded conditions, has a plurality of walls connected between bottom and top structures. A first wall of the plurality of walls includes first and second sections that connect together at a fold line about which the sections are rotatable between first wall collapsed and expanded conditions. The first section is connected to the bottom structure and the second section is connected to the top structure. The first wall is expandable by rotation of the first section relative to the second section in a first direction of rotation about the fold line from the first wall collapsed condition and into engagement with an abutment at the first wall expanded condition which arrests further rotation of the first section relative to the second section. The first wall is maintained in the first wall expanded condition by a load applied to the first wall.

Aspects of the disclosure relate to an article carrier for packaging a plurality of flanged articles, a blank for forming the article carrier. The article carrier comprises a plurality of primary panels for forming a tubular structure and defining an interior thereof. The plurality of primary panels includes a first panel and a second panel opposing the first panel. The article carrier further comprises a partition structure for dividing the interior into two or more article-receiving cells. The partition structure is formed from the first panel and comprises a lateral partition panel. The lateral partition panel is hingedly connected at a proximal end to the first panel by a proximal end fold line and is hingedly connected at a distal end to a glue panel by a distal end joint. The distal end joint between the lateral partition panel and the glue panel comprises a twistable strip extending between and joined with the lateral partition panel and the glue panel.

A return shipping system can include an outer container and a collapsible shock absorbing frame which can include a resilient sheet attached thereto for providing retention or suspension packaging of an article to be shipped within the outer container. The outer container can have a collapsed state suitable for shipping with the collapsible shock absorbing frame nested therein, the collapsible shock absorbing frame also in a collapsed state. The outer container can have an erect or expanded state suitable for shipping with the collapsible shock absorbing frame nested therein, the collapsible shock absorbing frame being in a locked or deployed state and configured to retain an article for shipping within the outer container.
