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.

A double seaming structure 100 includes a first metal member 111 having a first turned-back portion 113 at a first end portion 112 and a second metal member 121. A first region 115 including the first end portion 112 of the first metal member 111 and a second region 125 including a second end portion 122 of the second metal member 121 are in close contact with each other and sealed.

An energy storage system is provided. The energy storage system comprises an energy storage apparatus, a mounting frame body and a connector, wherein the mounting frame body is provided with a storage space, the energy storage apparatus is arranged in the storage space, and the mounting frame body is connected to the energy storage apparatus by means of the connector.

An assembleable container for storing a liquid includes an upper main body having a first connector and a lower main body having a second connector. The first connector has a convex portion or a concave portion formed on an outer periphery of the upper main body. The second connector has a concave portion or a convex portion that is formed on an inner periphery of the lower main body and configured to fit into the convex portion or the concave portion of the first connector. When the first connector and the second connector are coupled to each other, a bottom surface of the first connector and a bottom surface of the second connector are disposed facing each other. The first connector and the second connector are coupled to provide a leakage prevention portion for preventing the liquid from leaking.

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.

Provided is a foldable box. The foldable box capable of being deformed in a box mode, a development mode, and a collection mode includes a bottom portion, a plurality of side face portions connected to the bottom portion, and a plurality of connection portions connecting two adjacent side face portions to each other in the box mode, wherein in the development mode, the plurality of side face portions are developed in an outward direction and located on a same plane as the bottom portion, at least one collection fold line in a diagonal direction exists on each face of first and third side face portions facing each other of the plurality of side face portions, and the foldable box is deformed from the box mode to the collection mode by folding the first and third side face portions along the collection fold line in an inward direction of the foldable box to be folded over the bottom portion.

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 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 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.
