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.

The present application relates to a new vessel, such as a bottle that may be used to hold, store, or transport matter, such as particulates or fluids, and vessel assembly system. The vessel is constructed of a unique nesting design. Multiple vessels may be stacked together and to form a cohesive interrelated structure.

Disclosed herein is a detachable interlocking system for securing at least two articles together, the interlocking system including: a first interfacing portion; ii. a second interfacing portion; iii. the first and second interfacing portions being in complementary arrangement configured to engage with one another in a first engaged position and are moveable to a second interlocked position; iv. locking means to interlock the first and second interfacing portions together; v. reciprocating means to receive and accommodate the locking means; wherein movement from the first engaged position to the second interlocked position engages the locking means to interlock the first and second interfacing portions together.

A bottle including a finish defining a bottle opening, a collapsible assembly carrying the finish, the collapsible assembly including a first groove coupled to a second groove by a connecting portion, a bell coupled to the collapsible portion, a base, a central axis extending from the finish to the base, and a sidewall extending between the bell and the base. The collapsible assembly is configured to actuate along the central axis between a first extended position and a second depressed position, in the first extended position the first groove is positioned further away from the base than the second groove, and in the second depressed position the first groove is positioned closer to the base than the second groove.

A container system having at least two containers, wherein the container system comprises a light member which is configured to provide information through the emission of emission of chemiluminescent light, wherein the container system is configured to provide or trigger the light member to provide the information through the emission of light when a step related to preparation of a mixture of the contents of the containers is performed. In particular, triggering occurs when the containers are separated from one another and/or when a fluidic connection is created between the containers.

A connecting system for providing a fluidic connection, preferably between containers, wherein the connecting system has at least two connecting arrangements configured to provide the fluidic connection, namely a first connecting arrangement and a second connecting arrangement, each of which is fluidically sealed in an initial state, wherein the first connecting arrangement has, in particular, an opening region that is deformable outside the opening region and is configured such that deformation causes the first connecting arrangement to open in the opening region.

A stackable plastic container includes a base with a recessed portion; a sidewall portion; a shoulder; and a spout configured to dispense contents. The shoulder and spout may be configured to move downwardly in a vertical direction toward the base. In embodiments, the recessed portion may be configured to receive or cover at least a portion of a spout of an identical container. In embodiments, one or more containers in a retracted configuration may be stacked.

A cosmetic applicator includes a bottle and one or more sections that are removably attachable to one another in a stacked configuration. The bottle includes a reservoir, a first roller ball housing, a first fastener, and a first recess including a second fastener. Each section includes a receptacle, a second roller ball housing, a third fastener, and a second recess including a fourth fastener. The first recess removably receives the second roller ball housing. The second recess of a first section removably receives the second roller ball housing of a second section. The third fastener of a first section engages the second fastener of the bottle and the fourth fastener of a second section to allow connection of a section to the bottle and connection of the sections to each other, thereby enabling attachment of the bottle and the sections to one another in an interchangeably stacked configuration.

Embodiments of the present invention generally relate to a nestable beverage can comprising a voluminous body defined by a top portion, a bottom portion and a sidewall, the top portion comprising a single opening into the voluminous body; a pull tab and semi-weakened surface covering the single opening, wherein the semi-weakened surface covering the opening remains attached to the top portion in an open position; a connection member positioned at the top of the can for connecting the can to an additional can; and a receiving ring shaped to couple with the connection member, the receiving ring shaped to attach to the base of the can.

A beverage container is formed of a stacked array of interlocking single-serving container segments which allows indefinite storage of the container segments and which facilitates access to the beverage contained within a selected container segment without compromising the remaining quantities of the beverage
