A collapsible display unit includes a first tab protruding from a free edge of a first widthwise sidewall that is insertable into a slot in a base panel. A second tab protrudes from a free edge of an opposing second widthwise sidewall that is insertable into a slot in the base panel. A hinge in the base panel extends lengthwise between two free edges and through a center of the base panel. A hinge in the first widthwise sidewall extends between two free edges and through a center of the first widthwise sidewall. A hinge in the second widthwise sidewall extends between two free edges and through a center of the second widthwise sidewall. The first lengthwise sidewall has opposing end flaps that remain affixed to portions of the widthwise sidewalls for configuration between assembled and collapsed configurations.

Devices and systems for collapsible engagement mechanisms are described herein. In some examples, one or more embodiments include a front panel, a first side panel connected to the front panel, a second side panel connected to the front panel, and a collapsible portion connected to at least one of the first side panel and the second side panel, where the collapsible portion is collapsible about a hinge.

A cementitious composition comprises cement and crystalline cellulose or nanocrystalline cellulose formed from a cellulosic material by a redox reaction.

The present invention is directed to a bag for storing quilts, afghans, linens, blankets, hand-made clothing and other hand-made items. The present invention is further directed to a novel method of folding the item using interior flaps to protect the item. The storage bag of this invention includes an outer layer comprising a breathable, non-woven material, an interior layer that prevents damaging the quilt, a non-snagging sliding fastener proving access to an interior of the bag, and one or more interior flaps to protect the folded item.

A main body for a carrying box includes first and second side walls, and a pair of first connection walls and a pair of second connection walls that are pivotally hinged to opposite ends of the first and second side walls and are pivotally hinged to each other. The main body further includes a latch assembly having a bracket and a latch disposed at the first and second side walls, respectively. When the first and second connection walls pivot, a distance between the first and second side walls is reduced and a volume of the main body is reduced. The bracket is automatically fastened to the latch as the bracket and the latch are pressed toward each other.

The current invention discloses a container for the transport of piece goods, whereby said container is selectably configurable between a folded configuration and an expanded operational configuration. Said container is comprised of a container body which has two pairs of side panels defining an internal compartment, a bottom and an open top surface. Said open top surface is closable by a lid attached to a side panel of said container and enclosing at least partially edges of those side panels not connected to said lid, characterized in that said lid is attached to said side panel by a hinge portion, whereby the container body in said folded configuration is rotatable along a longitudinal axis along said hinge portion to allow at least partial stowage in said lid.

A collapsible storage box contains: a bottom plate, a first long plate, a second long plate, and two foldable short plates. Each foldable short plate includes a first connection sheet and a second connection sheet. A front end of the bottom plate retains with multiple first L-shaped hooks on a bottom of the first long plate, multiple first rotary shafts on a rear end of the bottom plate rotatably connect with multiple first retainers on a bottom of the second long plate respectively, a first side of the bottom plate retains with a first flexible hook on a bottom of the first connection sheet of each foldable short plate, and a second side of the bottom plate retains with a second flexible hook on a bottom of the second connection sheet of each foldable short plate. Thereby, the collapsible storage box is expanded and retracted quickly and easily.

A collapsible folding container to provide a safe and secure location for delivered packages, comprising a base panel that is securably attached to a base frame, the base frame that is vertically mountable on a structure that is permanently hinged to the rear edges of a left side rear panel, a right side rear panel, a lid, and a bottom plate, a front panel permanently hinged to the front edges of the left side front panel and right side front panel, the left side rear panel permanently hinged to the rear edge of the left side front panel, and the right side rear panel permanently hinged to the rear edge of the right side front panel.

Provided herein is a collapsible bulk-sized shipping box made of corrugated plastic. The rectangular box comprises four joined sidewalls, wherein left and right sidewalls are bisected by vertical fold lines allowing the sidewalls to be collapsed inwards. Bottom flaps also extend from the bottom of respective sidewalls and hinge inward about a fold line to provide a bottom side of the box when in use or fold flush with the sidewall when collapsed. The front wall of the box comprises a door flap that hinges inward and outward about a fold line. In addition, a door retaining puck attached to an outer surface of the front wall and configured to resist the door flap opening outward but deflect under application of sufficient force thereby allowing the door flap to open outward completely and provide access to the interior of the box.
