Various embodiments of a thin-walled metal container, such as a cup are described. The thin-walled metal cup includes a body with a tightly curled lip at the top end of the cup. The body includes a plurality of sections such that the diameter of the cup may be different at different places along the height of the cup. The thin-walled metal cup is designed to be light weight with a shape configured to facilitate grasping or holding the body of the cup.

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.

A modular structure system includes a plurality of shipping containers arranged to form a contiguous enclosure comprising an interior volume of the plurality of shipping containers, wherein each of the plurality of shipping containers comprises a first side defining an opening configured to be arranged opposite and adjacent to a corresponding opening in a first side of a different shipping container of the plurality to form the contiguous enclosure; a bottom group of the plurality of shipping containers including bottom sides having floor sections arranged to form a bottom floor of the modular structure; a top group of the plurality of shipping containers including top sides having ceiling sections arranged to form a top ceiling of the modular structure; and a side group of the plurality of shipping containers comprising a second side having a side wall arranged to form exterior right and left side walls of the modular structure.

A collapsible crate includes a structural base and at least one collapsible corner post assembly coupled to the base. The corner post assembly includes supports configured to provide lateral protection to a payload in the crate. The corner post assembly is moveable between an upright position and a collapsed position. The crate can further be stackable and/or returnable.

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 inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with a lower wall portion of a chuck wall, and the chuck wall has an 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.

A modular structure system includes a plurality of shipping containers arranged to form a contiguous enclosure comprising an interior volume of the plurality of shipping containers, wherein each of the plurality of shipping containers comprises a first side defining an opening configured to be arranged opposite and adjacent to a corresponding opening in a first side of a different shipping container of the plurality to form the contiguous enclosure; a bottom group of the plurality of shipping containers including bottom sides having floor sections arranged to form a bottom floor of the modular structure; a top group of the plurality of shipping containers including top sides having ceiling sections arranged to form a top ceiling of the modular structure; and a side group of the plurality of shipping containers comprising a second side having a side wall arranged to form exterior right and left side walls of the modular structure.

An apparatus is provided having an open configuration and a closed configuration. The apparatus includes, while in the closed configuration, a first panel, a second panel, a third panel, a fourth panel, a fifth panel, and a sixth panel that together create a box partially enclosing a void space. The first panel is rotatably coupled to the fifth panel and the sixth panel, the second panel is rotatably coupled to the fourth panel and the sixth panel, and the third panel is rotatably coupled to the fourth panel and the fifth panel. The apparatus opens from the closed configuration to present the contents therein through a single degree-of-freedom mechanism where the first, second, and third panels become perpendicular to the fourth, fifth, and sixth panels while the fourth, fifth, and sixth panels become aligned in a same plane.

An enclosure is provided that includes a main housing, a top housing, and a front housing. The main housing defines at least a rear wall of the enclosure, the top housing defines a top wall and a pair of side walls of the enclosure, and the front housing defines a front wall of the enclosure. The top wall has a convex curved portion that spans between side walls, where the convex curved portion has an angle that slopes downward from the rear wall towards the front wall.

An enclosure for a pulverizer system includes a generally cylindrical body forming an internal cavity having a central axis, a cover positioned above the cylindrical body, and a floor positioned within the internal cavity of the cylindrical body, opposite the cover, the floor having a surface extending from a point nearest the central axis to an inner sidewall of the cylindrical body. The surface of the floor has a substantially constant radius of curvature.

An apparatus is provided having an open configuration and a closed configuration.
