An aluminum alloy and recycle method are provided in which the recycled used beverage containers form an alloy composition useful with relatively minor compositional adjustments for body stock.

A refuse receptacle 10 comprising a plurality of wall panels 11, 12 joined to each other about a plurality of hinged joint arrangements 13. The refuse receptacle 10 comprises a first configuration being a generally planar storage configuration, and a second configuration, wherein the wall panels 11 are positionable relative to each other to form a receptacle having a refuse accepting space 14 defined by said plurality of wall panels 11. Advantageously, the refuse receptacle 10 can be quickly deployed for use from the first configuration to the second configuration, and returned to the first configuration for storage when use is complete.

A metal sheet for containers includes a metal sheet and a polyester film which is laminated on a surface of the metal sheet to be an inner surface side of containers. The polyester film contains a wax in an amount of 0.010 to 2.000 mass %, and has a dipole-dipole force of 40 mN/m or less.

This can for an effervescent beverage includes an upper surface, a lower surface, and a middle part. On the inner surface of the middle part, a plurality of first recesses is formed, each having a diameter of at least 5 μm. The number of the plurality of first recesses is 200 to 2,000 per 1 mm.sup.2.

An embodiment relates to a multi-layer, biaxially oriented polyester (BOPET) film comprising a food contact substance, wherein the BOPET has a percent release in a retort test after can lamination such that substantially all food contacting the BOPET during the retort test is released. Another embodiment relates to a method comprising applying a food contact material comprising a food contact substance to a multi-layer, biaxially oriented polyester (BOPET) film, wherein the food contact material is prepared at around room temperature without heating.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A proppant discharge system has a container with an outlet positioned in a bottom thereof and a gate affixed adjacent the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position.

A foldable storage box has four hard side surfaces in a vertical direction, a soft bottom surface, and a hard support plate that matches the bottom surface and is disposed on the bottom surface. Each of the side surfaces has a non-woven fabric interlayer, and a hard plug board is inserted in the interlayer. At least one pair of the four side surfaces are capable of being folded along a vertical folding axis. Vertical flexible dividing lines are disposed at intersections of the four side surfaces and the vertical folding axis, and the flexible dividing lines confine and isolate the respective hard plug boards in a horizontal direction. The flexible dividing lines are formed by welding two layers of non-woven fabrics in an ultrasonic welding manner.
