Two-compartment container

A process for preparing a container holding two separate components of a formulation to mix with one another prior to use, the process comprising:

• (a) providing a body for use as a housing of a container, having an internal space extending between two open ends and neck portion intermediate the two ends;
• one of the two ends, which is the bottom end of the container, being fitted with an axially displaceable member comprising a wall portion sealable engaged at the open end in a manner allowing axial displacement and comprising a partition wall dependent from said wall portion with an edge adapted for sealing engagement with the internal walls of the neck portion to define a first, bottom compartment and a second, top compartment, said displaceable member comprising a sealable filling aperture in said wall portion;
• (b) introducing a first component of said formulation into said first compartment through said filling aperture, and sealing said aperture;
• (c) introducing said second component into said second compartment through the other of the two open ends;
• and
• (d) sealing said other end of the two open ends.
