An explosion retaining housing includes a sheet metal member or outer skin which at least in part forms an interior region of the housing. At least one structural element provides additional strength to the member to retain the explosion in the region. The structural element can be inside of, or, outside of the region. The structural element can have a plurality of components which cooperate together to resist the force of an explosion in the interior region.

An anti-theft enclosure for protecting an outdoor air conditioning (A/C) unit is made up of an open framework of structural members which surround and protect the A/C unit. Individual steel panels are assembled to form a series of upstanding walls which are covered by a top panels and which together define the quasi-enclosed area surrounding the A/C unit. The tubing which makes up the steel panels is spaced to allow access to the enclosed area by a worker needing to access the A/C unit. The steel panels are joined with connecting and mating elements which facilitate easy and quick disassembling of the enclosure. The upright panels also have adjustable panel legs which can be extended and cemented into the ground for added stability and security

A composite includes a multilayer polyethylene terephthalate (PET) film having a base layer and an adjacent skin layer. The PET of the skin layer has inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T. The base layer can be affixed to a thin metal sheet. Optionally, the base layer of a second multilayer PET film with a skin layer inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T can be affixed to the opposite side of the metal sheet. The composite is suited for making food and chemical containers such as food storage cans that resist blush discoloration from steam contact during container formation and age degradation during extended storage of harsh chemical products.

A jewelry box comprising a lid, a drawer, a lift assembly and a jewelry holder; wherein the lid comprises a top, two parallel sides and an interior surface with opposing guide grooves on the interior surface of the sides; wherein the lid and drawer are sized to engage together and to slide to an opened position and a closed position; wherein the lift assembly is positioned in the drawer; the lift assembly having a down position when the lid and drawer are in the closed position and an up position when the lid and drawer are in the opened position; wherein the jewelry holder is positioned in the drawer attached to the lift assembly, and as the lift assembly moves from the down position to the up position, the jewelry holder pivots from the down position to the up position.

A blended polyester laminating film resistant to discoloration caused by cooking, comprising polyethylene terephthalate and polybutylene terephthalate. The blended polyester laminating film comprises three layers, i.e., upper, middle, and lower layers. One surface layer contains SiO.sub.2 in a mass fraction of 1200-2000 ppm added by in-situ polymerization. The blended polyester laminating film is manufactured by a three-layer coextrusion biaxial stretching method, and the manufacturing method is 240-275 C. A film-laminated metal sheet manufactured from the blended polyester laminating film has excellent resistance to discoloration caused by cooking, and is applied to metal containers for food and beverage packaging that require high-temperature sterilization.

A thinned metal can end having a non-uniform thickness profile is provided. The can end has a central panel having at least a first thickness, a middle portion having at least a second thickness greater than the first thickness, and an end portion having at least a third thickness greater than the first and second thicknesses. The can end is configured to be joined to a can wall by a double seam.

The resin-coated metal sheet for containers includes a resin coating layer (A) having a multilayered structure mainly composed of a polyester resin on at least one surface thereof. The resin coating layer (A) includes a resin layer (a1). The resin layer (a1) adheres to the metal sheet, contains (i) a polyester resin, (ii) a phenolic resin, (iii) a metal alkoxide compound and/or a metal chelate compound, (iv) an epoxy resin, and (v) at least one selected from the group consisting of polyamine resins, polyamidoamine resins, and polyamide resins, and is mainly composed of the polyester resin. Preferably, a polyester film (a2) is disposed on the resin layer (a1).

A three-piece can includes a can body obtained by forming a steel sheet such that a roundness of the can is 0.34 mm or less. The steel sheet contains: by mass %, C: 0.020% or more and 0.100% or less; Si: 0.10% or less; Mn: 0.10% or more and 0.80% or less; P: 0.001% or more and 0.100% or less; S: 0.001% or more and 0.020% or less; Al: 0.005% or more and 0.100% or less; and N: 0.0130% or more and 0.0200% or less. The balance is Fe and inevitable impurities. The steel sheet has a yield strength of 440 MPa or more and a total elongation of 12% or more.

A sheet metal planter comprises three panel types, can be assembled with readily available tools, can be disassembled to fit in a compact space, can be made in more than one shape, does not require fasteners in one embodiment or places a modest load on fasteners in another embodiment, and is aesthetically pleasing.
