Exemplary features of various embodiments include one or more of an overmolded pad on the bottom of the container, a removable handle incorporating a releasable retaining structure, a lid that seals within the container cavity and is flush with the outer periphery of the container sidewall and/or has a cellular internal reinforcing structure, a skirt extending around the sidewall that is integral with handle mounts for the handle and/or provides a connection point for external components, and a drop-in tray with a collapsible handle.

An accessory for use with a portable container includes a jacket having a storage member and configured to extend around at least a portion of the sidewall of the container and a connection member connected to the jacket and configured to support the jacket in connection with the container. The connection member includes a connector configured to be connected to a port on the container such that a portion of the connector is received through the port.

A collapsible nestable container is provided. The collapsible nestable container may comprise a plurality of panels, each having one or more locking features that interlock with the locking features of the other panels to form an assembled container. The panels further comprise one or more nesting features, that interlock with the nesting features of the other panels to allow the panels to nest in a collapsed configuration with similar or dissimilar panels.

A sealing structure for a plastic packing box, comprising: a packing box body, made by bending a plastic plate; top and bottom openings; and cover plates, configured on sides of each opening and bended inward to stack together to seat the opening, wherein a premade mating frame is respectively engaged with sealing end faces of the outer cover plates configured on two opposite sides of the main body and bended to each other to form a sealing edge, the mating frames are a male-female pair stacked together to sealing the box, ensuring that two end faces is neat after box body sealing, the opposite inner edges of the two mating frames are respectively configured with male and female buckling elements allowed to be pressed together to engage with each other after the stacking, thereby achieving stable and safe buckling, while the cover plate are stacked together simply.

According to the present invention, the device comprises: a flange having an at least approximately trapezoidal tapered section; a counter-flange having a shape complementary to that of said flange (1); and clamping means for clamping said flange and said counter-flange one in the direction of the other, interposing the edges of said elements shaped at least partially in the shape of said counter-flange.

The present invention discloses a lightweight and large-capacity garage kit carrying case, including a case body provided with a case opening door on a circumferential surface thereof. The case body is formed by splicing a plurality of double-layer plastic panels with hollow interiors; a plurality of small bumps are correspondingly formed side by side on opposite surfaces of the plastic panels, located on two sides of the case opening door, of the case body; a cargo chute is formed between two adjacent rows of upper and lower small bumps; and a tray capable of being pulled along a direction of the case opening door is erected between two cargo chutes arranged symmetrically. The case features light weight, high strength, large capacity, and high space utilization, making it convenient to carry a large number of garage kit models for board games.
