Abstract: The present invention provides a container system that allows a user to store ingredients of a formulation in separate individual containers that can be assembled easily into an extended single compartment container, thereby enabling to mix the ingredients, in a gentle shaking or swirling manner, to form the formulation prior to use.

Abstract: The present invention relates to a container unit for engaging with a second container, comprising: a) a container body having a neck portion, wherein said neck portion includes a first sealable opening; and b) a coupling mechanism disposed at said neck portion for enabling engagement with said second container for combining the volume of said container unit and said second container, wherein said coupling mechanism includes: i) a first ring-like seal located at an upper end of said neck and sized to engage an inner wall of an opening of said second container; and ii) a first shoulder, spaced apart from said first seal, sized and configured to sit on an open edge of said second container, wherein said shoulder is in removable abutting relation with the open edge of said second container, while said neck portion is inserted by a maximum extent through the opening of said second container, thereby defining the maximum extent of said first ring-like seal.

Abstract: A two-compartment container for separately storing two components, mixing the components and dispensing a formulation formed by mixing the two components, the container including (a) a housing having an opening at each of its top and bottom ends and a sealing wall located between the top and bottom ends which divides the housing into two separate compartments; (b) at least one connecting member extending between the sealing wall and an inner wall of the housing defining at least one opening for flow communication between the connecting member and the housing; (c) a substantially hollow displaceable member having a sealable sleeve, the displaceable member being disposed in the housing.

Abstract: The present invention relates to a divider device for use with a container having at least one opening, each such opening having an associated cap. The divider device includes a dividing wall for releasable sealing engagement with an interior wall of the container and for dividing the container into two separate compartments, a first compartment above the dividing wall and a second compartment below the dividing wall. The divider further includes an operable portion coupled to the dividing wall for moving the dividing wall between a sealed position, separating the first and second compartments, and an unsealed position, defining a flow passage permitting flow communication between the first and second compartments. The operable portion including means for engaging a closure member, so as to close said operable portion. The divider device is removably couplable to the container when at least partly disposed inside the container.
