A set of nestable and stackable cookware, for example, a set of pots and pans, is maintained in a stable configuration by stops attached to the outer walls of the cookware. Each stacked and nested item of cookware is supported on the rim of the lower item by two stops attached to its outer wall, on opposite sides of the item. Each stop is shaped and configured to contact the rim of the lower item in the stack at a finite number of points. A first stop contacts the lower rim at two points, and a second stop contacts the rim at one or two points. The points of contact lie in the same plane, which uprightly supports the stacked cookware item on the lower cookware item, without the walls or the base of the stacked cookware item touching the lower item.

A nestable beverage crate includes a base, side walls and end walls. Each side wall includes a plurality of side columns connecting a side upper band to the base. Each end wall includes a plurality of end columns connected an end upper band to the base. The side upper band and the end upper bands each have a plurality of peaks and valleys and are asymmetric, such that adjacent crates will have peaks aligned with valleys and vice-versa. For purposes of preventing shingling, the effective height of these two adjacent side walls is the full distance between the upper edge of the peak and the lower edge of the valley, but the nesting height of the crate is only the height of the upper bands.

The invention relates to the field of logistics, and discloses a logistics apparatus and a method for identifying empty/full state of the logistics apparatus, which efficiently and accurately realizes automatic recognition of empty and full state. The invention includes: a base and side plates at four sides; a foldable mechanism being provided between the base and each side plate so that the side plates can be folded toward the base; and a short-range wireless transmitter module and a short-range wireless receiver module being respectively disposed on the base and at least one side plate; the short-range wireless transmitter module is configured to transmit a wireless signal indicating the identification of the logistics apparatus; and an arbiter, configured to determine whether the short-range wireless receiver module can currently receive the identifier transmitted by the short-range wireless transmitting module, and if yes, outputting an electrical signal indicating an empty state, otherwise, outputting an electrical signal indicating a full state.

A tray includes a base and a pair of side walls extending upward from side edges of the base. Front and rear walls extend upward from front and rear edges of the base. The front and rear walls are shorter than the side walls. A plurality of support posts project upwardly from the upper edge of the front and rear walls. A lip is spaced outward of the front wall and the rear wall. Each lip includes a lower edge protruding downward to form columns aligned below the support posts. When stacked on a similar tray the columns contact the support posts of the similar tray to help support the front and rear walls. The base includes a recess below the columns for receiving the blade of a hand truck, which will transfer load throughout a stack of trays from columns to support posts.

Embodiments of this disclosure include a rigid tray container and methods and equipment for using the rigid tray container in batched process operations. In one embodiment, a mass container is sized and dimensioned to receive one or several rigid tray containers. In other embodiments, equipment is configured to lid/unlid, secure, stack, load/unload, and buffer rigid tray containers. In other embodiments, equipment is configured to stack and stage mass containers. In some embodiments, methods are provided for batch processing items.
