The portable container system includes a central locking hub that assembles a collection of containers into a carrying unit. The hub is cylindrical in shape and the containers are angular wedges projecting horizontally outward from the hub. Each container includes a vessel with a defined interior volume, and a lid. The containers are reversibly secured to the hub when the containers are received around the hub base, and the hub upper part is secured to the base, thereby locking the containers in place. A registration apparatus, comprising reciprocal pairs of extrusions and depressions in a circular pattern, is integrated within and between the mating surfaces of the central hub, and the containers. When the carrying unit arrives at its destination, the hub upper section is removed from the base. The user may then remove the containers as they see fit.

The reusable food transportation device, or food transportation system, includes a single hub that connects to a collection of containers. The hub is circular and the food containers are angular wedges projecting horizontally outward from the hub. Each food container includes a vessel and a lid. During transportation the hub, formed from an upper section and a lower section, compresses each lid against its respective vessel to prevent spillage of the food contained within. When the device arrives at its destination the upper section and the lower section of the hub are separated from each other. This removes the compressive force holding the lid and the vessel in place. The user may then remove the containers as they see fit.

A stackable plastic container includes a neck area; a body portion with a base; an integral handle part located around the neck area of the container, in which the handle part includes one or more handles for carrying and handling the container; and an integral first chime configured to receive and/or cooperatively engage the base of an identical container.

An ammunition organization system having a plurality of ammunition organization rows connected to each other through magnetic row couples to form an ammo stack, and a cover attached to the ammo stack row couples by magnetic cover couples. The ammunition organization system allows for ammunition to be stored neatly, while reducing the difficulty of extracting ammunition by allowing the rows to be selectively separated from or combined to each other. Each ammunition organization row has a known quantity of ammunition slots for holding ammunition, making it easy to determine the amount of ammunition held within. The ammunition slots also allow for easy identification of each round, allowing multiple types of ammo to be organized concisely within the same ammunition organization system. Alternative coupling methods including pins, clasps, or other coupling systems may also be used in connecting the ammunition organization rows to each other as well as the cover.

Implementations disclosed and claimed herein provide a customized storage system. In one implementation, a folding crate movable between a storage position and a collapsed position is provided. One or more customizable and modular attachments to the storage crates may be provided to attaching to or otherwise mating with a side of a crate. The modular attachments may include a universal connector that connects to an opening in any side of a storage crate and one or more accessories that mate with the universal connector, with each of the accessories having a specific use or utility, such as a cup holder accessory, a handle accessory, a tool holder accessory, and the like.

Bag holders for plate freezing of bags containing fluids such as reactor bags, in particular bags containing biological or chemical reagents can include genderless bag trays. Each bag tray can include a basin defined in part by a first side wall and a second side wall. The basin can be configured to hold the bag. The first side wall can include a first retaining feature and the second side wall can include a second retaining feature having a shape complementary to the first retaining feature. The complementary nature of first and second retaining features allows identical bag trays to be joined by each of their respective first and second retaining features to one another. Methods include forming first and second bag trays, placing a bag within the first bag tray, joining the second bag tray to the first bag tray, and freezing the bag by a plate freezing process.

A system for releasably connecting a plurality of interchangeable components in an assembly. The system includes a plurality of units and a plurality of interchangeable components capable of being releasably joined to one or more of the plurality of units. The plurality of units further includes a physical connecting system and a magnetic connecting system for relative positioning of at least one of the plurality of units with at least another one of the plurality of units. The physical connecting system includes a set of physical keys. The set of physical keys includes an indentation and projection on the surface of the unit. The magnetic connecting system includes a plurality of magnetic connectors housed in the interior housing of each of the plurality of units.

A shipping pallet arrangement includes a first pallet having a first underdeck opening to a first storage volume under a top deck, said top deck supporting goods for transport; and a first underdeck container holding goods and received within the first storage volume. A method for shipping goods in a transport container includes positioning a first pallet in the transport container, the first pallet having a first underdeck opening to a first storage volume under a top deck having goods thereon; storing goods within a first underdeck container; after the step of storing and the step of positioning, receiving the first underdeck container at least partially within the first storage volume; and after the step of receiving, shipping the transport container.
