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 fluid container in the form of a can having a neck defining an opening, and fastened in a water-tight manner to the neck a valve element with a valve cup supporting a hollow stem movable against an elastic element between a first stable closing position and a second unstable position for delivering fluid through a cavity in the stem, the cavity communicating with the interior of the can in a dispensing position, the can being fixed to a support base of the container, the base comprising a support surface with a recess defined by a first centering surface to center the container on a valve cup of an identical container, on top of which the container may be placed, a second support surface for supporting the container on the valve cup, and a third recessed surface to house the stem of an aerosol valve of the further container.

A container includes a finish, a shoulder portion, a body, and a base portion. The finish defines an opening. The shoulder portion extends from the finish. The body extends from the shoulder portion and defines a chamber. The base portion extends at an end of the body opposite to the shoulder portion and is moveable from an as-blown position to an expanded position and from the expanded position to a retracted position. The base portion includes a standing ring, a pivot area, and a central area. The pivot area is disposed between the standing ring and the central area. The pivot area is configured to flex and move the central area along the longitudinal axis when the base portion moves from the as-blown position to the expanded position, and from the expanded position to a retracted position.

A connecting system for providing a fluidic connection between containers, the connecting system having at least two connecting arrangements configured to produce the fluidic connection. Each container has an initial state in which the two containers are fluidically separated from one another and a connected state in which the two containers have been fluidically connected together by a relative movement of the containers. A securing device prevents relative movement of the containers in the initial state, and a receptacle is provided in which the securing device can be accommodated for enabling said relative movement. The system is usable in a method for preparing a mixture of substances in which the containers are placed in a connecting orientation with the securing device arranged between the containers in a manner preventing fluidic connection of the containers, and releasing the securing device for enabling fluidic connection the containers by a relative connecting movement.

A container having a center portion and two side portions each situated at an angle to the center portion and extending in opposite directions such that the a left half of the container is substantially identical to a right half of the container. The container includes recesses and protrusions which enable the container to stack in two orientations generally perpendicular to each other.

A tray system includes a first tray having a plurality of stacking units. In one embodiment, each stacking unit forms a lower receptacle for receiving a neck portion of a first bottle, and an upper receptacle for receiving a base portion of a second bottle to be stacked above the first bottle. The lower receptacle has a first end, a second end opposite the first end, and a sidewall connecting the first end with the second end. The first end forms an opening for receiving a neck of a first bottle into the lower receptacle. The sidewall has a taper that prevents racking. The tray system may also include a second tray and a pallet.

A beverage container assembly including a first beverage container having a first vessel body that has a first base having a first perimeter and a first side wall connected to the first base, wherein the first side wall includes a connecting member. The first beverage container including a first rim defined on the first side wall distal to the first base. The assembly further including a second beverage container that includes a second vessel body that has a second base having a second perimeter and a second side wall connected to the second base. The second side wall includes an engagement member that engages with the connecting member so that the first beverage container is attached to the second beverage container.

A crate for storing containers includes a plurality of walls and a base connected to the plurality of walls. The base includes a plurality of recessed areas each having a first container contact surface spaced from a second container contact surface.

A container having a center portion and two side portions each situated at an angle to the center portion and extending in opposite directions such that the a left half of the container is substantially identical to a right half of the container but rotated 180 degrees to form a Z shaped profile of the container. This Z shaped profile allows containers to be stacked upon each other to provide space savings in storage and shipping of the container and the container when filled with liquid.
