A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape.

Provided is a cushioning material obtained by stacking a plurality of cushioning sheets, in which the plurality of cushioning sheets include a first cushioning sheet, a second cushioning sheet having a strength stronger than that of the first cushioning sheet, and a third cushioning sheet having a strength stronger than that of the second cushioning sheet.

The construction and design of new multi-laminate sheet materials for the fabrication of shipping containers, boxes, furniture, consumer items, and many other products, including those generally using panels in their design, is disclosed. These new materials are produced by employing advanced folding techniques, to yield lightweight, cost effective multi-laminates. At least one layer in the multi-laminate structure is a folded sheet tessellation which, in some embodiments, can have doubly periodic folded geometries with fold creases in multiple non-parallel directions. The various layers of the construction can interlock with each other to collectively provide mechanical stiffness, strength, energy absorption and other properties.

A packaging system for a hot water heater includes an outer box, a top insert, an offset filler, a base insert, and one or more side panels. The top insert contacts a top surface of the hot water heater and a top inside surface of outer box. The offset filler is coupled to the top insert and is sandwiched between the hot water heater and the outer box. The base insert contacts the bottom surface of the hot water heater and a bottom inside surface of the outer box. The base insert includes raised perimeter structures that form a shape that matches a shape of the bottom surface of the hot water heater. The raised perimeter structures and the offset filler position the hot water heater off-center with respect to a center axis of the outer box. Each side panel includes a raised pattern.

To improve operability when an object to be stored is taken-out and stored and portability. A main case includes a first bottom-plate, a first side-wall, and a first space. The first side-wall includes four sides including a first side. The first side-wall includes a first side-plate opposite to the first side and is connected with three sides different from the first side. The first space is partitioned by the first bottom-plate and the first side-wall. The cap includes a second bottom-plate, a second side-wall, and a second space. The second side-wall has four sides including a second side. The second side-wall includes a second side-plate opposite to the second side and is connected with three sides different from the second side. The second space is partitioned by the second bottom-plate and the second side-wall and has a volume larger than a volume of the first space. The connection plate is connected with each of the first side and the second side and is foldable to the first bottom-plate and the second bottom-plate. The grip member is attached to the first side-plate and is capable of penetrating into the second side-plate in a closed state in which the first side-wall is housed in the second space.

The present disclosure discloses a packing box in the field of outer packing technique in view of problems that the existing thick packing box occupies large space in transporting and storage and cannot be reused after disassembled due to adhering connections. The packing box includes two cover bodies configured to snap one another, each of the cover bodies is formed by a folded plate member, and the plate member includes an internal flexible layer, an external flexible layer and a paperboard layer therebetween, where the cover body includes a bottom plate, and a side plate and a flipping plate both arranged on each of opposite sides of the bottom plate, one side of the side plate is connected to the bottom plate, and the other side of the side plate is connected to the flipping plate, so that the side plate is foldable with respect to a side edge of the bottom plate that is connected with the side plate, and the flipping plate is foldable with respect to a side edge of the side plate that is connected with the flipping plate. A locating structure is arranged between the bottom plate and the side plate, and a free end of the flipping plate is configured to be inserted and fixed to the locating structure. Since adhering connections are avoided in the assembling of the packing box, the production efficiency is increased, and the packing box is easy to disassemble and assemble and may be reused, so that the cover body can be disassembled to save space for transporting and storage.

A container is disclosed. The container includes a fillable bladder in an interior of an enclosure of the container. The container has a sump region which assists in the removal of a pumpable product from the fillable bladder.

A packaging system for a hot water heater includes an outer box, a top insert, an offset filler, a base insert, and one or more side panels. The top insert contacts a top surface of the hot water heater and a top inside surface of outer box. The offset filler is coupled to the top insert and is sandwiched between the hot water heater and the outer box. The base insert contacts the bottom surface of the hot water heater and a bottom inside surface of the outer box. The base insert includes raised perimeter structures that form a shape that matches a shape of the bottom surface of the hot water heater. Each side panel includes a raised pattern.
