The present disclosure relates to a method for manufacturing a nestable water tank, the method comprising molding a water tank comprising a hollow cylindrical body and cutting the water tank to form the nestable water tank comprising a tank body and a lid, wherein the tank body comprises: a side wall comprising a cylindrical shape running along a vertical axis, an interior surface, and an exterior surface; and a bottom connected to a bottom portion of the cylindrical tank, together forming a nestable water tank interior space capable of storing water within the nestable water tank interior space and comprising an interior bottom surface and an exterior bottom surface, wherein at least one of the tank body and the lid are each nestable with other similarly shaped tank bodies and lids.

An exemplary approach for protecting floorings in containers may utilize a first ledger attached to an upper portion of a first support beam associated with a foundational base assembly. A portion of the first ledger may protrude outward in a first horizontal direction from the upper portion of the first support beam. A second ledger may be attached to an upper portion of a second support beam next to the first support beam. A portion of the second ledger may protrude outward in a second horizontal direction from the upper portion of the second support beam. The second horizontal direction may face the first horizontal direction. A support panel may be placed on top of the portion of the first ledger and the portion of the second ledger. The support panel may have a length proximate to a distance between the first support beam and the second support beam.

The invention discloses a liquid conveying system, a liner bag and a manufacturing method. The liner bag comprises a liner bag body and a discharge port, the liner bag body is formed by sealing and welding a front panel and a rear panel along the periphery, and the discharging port is sealedly connected with the liner bag body. The liner bag body is substantially rectangular, and the liner bag body has two pairs of opposite side edges, and corresponding adjacent side edges of the two pairs of opposite side edges are connected by one or more transition edges The liner bag of the invention is simple to manufacture and does not form a damming lake during the liquid discharge process, which is especially beneficial for the discharge of viscous liquid, and less liquid remains after the discharge is completed.

An expandable storage container comprises a floor and two longitudinal walls, each wall comprising at least one arm, with the wall connected through the arms to the floor so as to provide lateral extension of the longitudinal walls away from the floor. In certain embodiments, the arms are slideably or hingedly connected to the floor to provide lateral extension.

A container including a first panel with a first edge having a first protrusion with a first contoured profile with at least one projection, a second panel with a second edge having a second protrusion with a second contoured profile with at least one projection, and a spline with a first channel that defines a recess with an interior profile, and a second channel separate from the first channel that defines a recess with an interior profile. The first and second channels receive the first and second protrusions, respectively, such that the first contoured profile is complementary to a portion of the interior profile and the second contoured profile is complementary to a portion of the interior profile. The first and second panel include a mid-section extending from the first and second edges, respectively. The first and second edges have a greater thickness than the thickness of the mid-sections.

A cylindrical cargo container is formed of longitudinal, extruded arcuate panels joined pairwise at abutting edges to form a cylindrical tube. The container is mountable on a separate wheeled chassis to form a semi-trailer or railcar, or a chassis integral with a truck. The container may be substantially smooth on inner and outer surfaces, to provide optimal aerodynamics and freedom of motion of cargo within the container. The panels may have inner and outer skins bridged by multiple webs. Such structure may provide protection from punctures to the outer or inner skins. The container is useful to transport waste including municipal or industrial waste, and may be part of a tipper trailer. The container, trailer, truck, or railcar may be used with a compactor for compacting the waste within the container.
