A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuck wall at a junction below the center panel, and the chuck wall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuck wall extends at an angle greater than the angle of the inclined lower wall portion of the chuck wall.

An equipment locking system. The system includes a base container forming a partial enclosure. The base container including a bottom wall, a set of sidewalls, a rotatable anti-intrusion lid, and a locking mechanism that form a partial enclosure. The partial enclosure is configured to enclose a piece of equipment. The partial enclosure is configured to prevent access to the piece of equipment when the rotatable anti-intrusion lid is closed. Portions of the piece of equipment may protrude from gaps in individual sidewalls of the set of sidewalls. The rotatable anti-intrusion lid can be coupled to a sidewall of the set of sidewalls and rotated about the sidewall. Portions of the rotatable anti-intrusion lid can be inserted in the locking mechanism. The locking mechanism may restrict rotation of the rotatable anti-intrusion lid when the rotatable anti-intrusion lid is in the closed position, and the locking mechanism is in a locked position.

The invention relates to a container for preserved food comprising a metal body having at least one end closed hermetically by a bottom formed by a flexible film.

A method of incremental autofrettage is taught herein, whereby the cycle life of a metal liner in a pressure vessel is increased. This method serves to increase the yield strength of the metal liner through sequential work hardening due to repeated autofrettage at increasing pressures. By incrementally increasing the internal pressure used in the autofrettage process, the compressive stresses at an inner surface of the metal liner may be controlled so that post-pressurization buckling does not occur, yet the yield strength of the metal liner is substantially increased. The higher compressive stresses in the metal liner mean that higher Maximum Expected Operating Pressures (MEOPs) may be used without detracting from the cycle life of the metal liner, or alternatively, for lower pressures, a longer metal liner cycle life may be obtained. Either internal or external pressures may be used, generated by a pressure source, or a suitable die.

Disclosed is an apparatus of housing component which includes a case which accommodates a component, a cover which covers the case, and a sealant applied on a joining surface at which the case and the cover join together, wherein a step is formed at the joining surface.

A method for joining shipping containers together to create a modular structure includes providing a first shipping container and a second shipping container; removing a wall of the side of the first shipper container to create a first opening; removing a wall of the side of the second shipping container to create a second opening; positioning the first opening adjacent and opposite to the second opening; aligning the first opening with the second opening; after the aligning, securing the first shipping container to the second shipping container to create the modular structure; and securing an inner flashing around an inner periphery of the first opening.

What is disclosed is an assembly system to create customizable, mobile, lightweight containers and container-like products ranging in size from consumer and commercial storage products to shipping containers and small mobile buildings. The system uses slidable interconnection of various profile shapes of elongated panel modules with same length standardized linear and corner panel connectors, to create container sleeves retained by customizable end framing to become container shells. The container shells are customized to size needed by the number of interconnected panel modules used and the length to which they are cut. Assembly of their few basic parts is simple with a limited range of tools and skills needed. The system further provides for simple, seamless, solid and reversible structural attachment of third party components, without welding or riveting, to achieve specific customization goals as needed. Finally, the system provides for easy and scar free disassembly for shipping, storage reconfiguration, or recycling.

A grain storage bin includes a cylindrical wall formed by a plurality of panels arranged in rows with a bottom edge of a first row bolted to a top edge of a second lower row. At each joint the bottom edge of the first upper row is overlapped with and outside of the outer surface of top edge of the second lower row and the bottom edge is fastened to the top edge by bolts carrying spacers as to define a first channel along the joint for passage of air. A cover strip overlies the channel and extends from an upper edge of the strip at the inner surface of the first panel above the channel to a lower edge of the strip which is fastened to the top edge so as to define a second channel so that air can pass between the interior and the exterior through the first and second channels while the particulate material is prevented from escaping through the first channel by the cover strip.

Embodiments described herein include layered mesh containers and methods for using the containers to safely transport and dispose of airbag inflators having ammonium-nitrate-based propellant. For example, a container is provided that can hold multiple airbag inflators and withstand up to 4 moles of matter being deployed from an inflator having ammonium-nitrate-based propellant. The container can contain the inflator and any shrapnel associated with the explosion while also venting gases expelled as a result of the explosion. Various container designs are provided, along with methods for using these containers.
