Described are devices and containers that are scalable, modular, and lockable laterally and vertically with other like containers for a variety of applications. A container is formed by a wall attached at first end to a top end section with an opening and attached at a second end by a bottom end section. A container may have one or more of a tongue, formed on the wall, having and interconnecting mechanism to be received and interlocked by a groove. Vertical interconnectivity is accomplished with mechanisms to stack containers and prevent swivel using a ridge and channel interlocking arrangement.

A measuring device assembly having a container and measuring receptacle. The container includes a self-supporting base structure with a plurality of projections extending downward therefrom, wherein each projection of the plurality of projections includes a fastener receiving groove extending inward thereof. The measuring receptacle includes a receptacle base, a side wall extending from an upper surface of the receptacle base, and a fastener extending inward and secured in the fastener receiving groove.

A storage device includes a storage body, which includes a bottom surface, wall surfaces surrounding a storage space, a front opening portion and an upper opening portion such that a package body is enabled to be inserted into the storage space from a plurality of directions, a front guide, which is provided on the bottom surface in proximity to the front opening portion, and includes an inclined surface descending toward a surface on a back side of the storage space among the wall surfaces, and a rear guide, which is provided on the surface on the back side in proximity to the upper opening portion, and restricts upward movement of the package body stored in the storage space along the surface on the back side.

A container has a top and a bottom endcap, a bottle sandwiched therebetween, and one or more bands coupling the top and bottom endcaps and the bottle. The bottle receives therein a flexible bladder. At least one of the top and bottom endcaps has a pair of opposing parallel surfaces, one of which has a protrusion extending therefrom and the other one of which has a recess therein at a location corresponding to that of the protrusion. A valving structure demountably engages with a neck portion of the bottle and has (i) a coupling valve assembly having two channels in fluid communication with the bottle and the bladder for injecting gas thereinto and dispensing liquid therefrom, respectively, and (ii) a twist-lock casing receiving therein the coupling valve assembly and removably coupled to the bottle's neck portion. The twist-lock casing has a structure for safely depressurizing the bottle.

In one embodiment, a tool container system includes a container with base and cover pivotably attached by a hinge, base and cover locking members, and a latch moveable between unlatched and latched positions to allow or prevent movement of the cover relative to the base. The system also includes a utility knife blade retainer configured to be received in and held by the container, the retainer configured to define a generally trapezoidal shape and contact multiple faces of blades received therein. The retainer comprises an engagement feature to engage with the container to limit movement of the retainer. In another embodiment, a knife blade retainer is configured to be received in a container. The retainer includes a generally trapezoidal shape defined therein to contact multiple faces of a trapezoidal shape of blades received therein. An engagement feature engages with the container to limit movement of the retainer within the container.

Described herein are various coupling systems to be used with storage units that are selectively coupled and decoupled. The coupling systems may be used with storage units that are stackable and/or transportable, thus allowing the storage units to function well within a large stationary environment, such as a basement, and also for a subset of the storage units to be selected and easily moved to another location.

Building block container is a modular hollow building block that may be used to build a wall, shelter, structure, building, greenhouse, water filtration device, emergency shelter, pipeline, flood blockade, floodwall, dock, or raft. Building block container has a special design so that they are reversibly attachable to each other without fasteners. Building block container may also be used as a container to hold any type of liquid or solid contents. A plurality of building block container may be shipped to a disaster area, third world location, or anywhere with people in need, while filled with water or food, where the water or food may be consumed by those in need and then the empty building blocks may be used to build a wall, shelter, structure, building, etc. One or more building block containers may also be used as a water filtration device to filter unclean water into drinkable water.

Stackable packaging modules for packaging oblong objects with a U-shaped profile made from synthetic material, formed by a horizontal bottom profile and two upright legs which can be fixed, or collapsible whereby the horizontal bottom profile along both upright long sides is provided with at least two protrusions and at least two hollow recesses in which the at least two protrusions and at least two recesses of a horizontal bottom profile of an adjoining module fit. The horizontal bottom profile is provided on the underside over the whole length with a slit-shaped recess in which a fork of a forklift truck, reach truck or side loader fits.
