Abstract: A multiple container package includes four containers which each have a polyhedral body portion with an elongated neck portion. The body portion of each container has lateral polygonal side walls, spaced apart front and rear walls a top shoulder and bottom wall. A recess which is perpendicular to the neck extends either in the front wall or the rear wall and receives the neck of an adjacent container. Four containers can be mated together to form a package having a polyhedron volume with the volume being substantially filled by the containers.

Abstract: A mateable bottle having a hollow L-shaped body is disclosed which has a neck portion formed as a neck rib in an inner front wall surface of the body. The neck terminates in a stub spout which has a large diameter opening, opening into the interior of the hollow body. A concave recess, provided in an outer front wall surface, is shaped to receive a neck rib of a mated container. Outer surfaces of two mated bottles are provided with planar and perpendicular surfaces so that a rectangular solid is formed when the two bottles are mated to each other.

Abstract: A container package comprises a plurality of individual containers which each have a hollow polygonal body from which an elongated hollow neck extends. Each hollow body has side walls, a bottom wall and a top shoulder wall. A recess is provided either in the bottom wall or one of the side walls for receiving the neck of an adjacent container in the package. The containers are mated together and form a polyhedron. The containers may have interior volumes which are different from each other so that the containers contain different amounts of materials or may have identical volumes but be shaped differently from each other. At least one of the recesses may also contain a secondary container which, together with a neck of another container, substantially fill the recess.

Abstract: A multi-purpose container unit whose hollow body, neck and shoulder sections are proportioned and constructed in a manner that allows interfacing and mating with an identical or mirror image unit of like size, volume or exterior proportions in mirror image. The container has a neck and a recessed portion along its vertical axis which accepts and provides safe harbor and protection to the neck and closure portion of a first container of the mated unit whose corresponding body recess, in turn, accepts its neck and closure portion of a second container of the mated unit resulting in a new composite geometrical shape such that the outside dimensions of the mated pair of containers provides improved packing economy.

Abstract: A multiple container package includes identical containers, each having an elongated neck and a body portion with a recess which extends in a substantially transverse direction relative to the neck. The neck of each container is received with the recess of the body portion of another container.
