Abstract
A container holding two separate components which are mixed prior to use is provided. The container comprises a housing with a dispensing opening and neck portion between said opening and the bottom end of housing. The container further comprises a displaceable member disposed within the housing and having a partition wall with an edge adapted for a sealing engagement with internal walls of the neck portion, thereby defining two compartments separated by said partition wall. A displaceable member is axially displaceable between two positions along an axis extending through the neck portion. These two positions comprise a first position where the edge of the partition wall sealingly engages the internal walls of the neck portion, and a second position where the edge of the partition wall and the internal walls are disengaged permitting flow communication between the two compartments. This flow communication allows mixing of the two components to form a formulation which is then ready for use.
