Patent ID: 8413845

Claim:
A dual-compartment dispensing container for retaining and dispensing two separate products or product phases such that each product or product phase is concurrently dispensed from each compartment in substantially equal volumetric amounts, wherein said container comprises a first inner compartment comprising a deformable semi-circular inner tube formed from a semi-circular wall, which wall has a first edge and a second edge, and a flat wall opposed against said first and second edges to form a first cavity, said inner tube having a top end and a bottom end, said inner tube being disposed within a second outer compartment comprising a deformable fully circular outer tube having a circular wall, and forming a second cavity, said outer tube having a top end and a bottom end, such that: (a) the semi-circular wall of the inner tube conforms to and abuts the circular wall of the outer tube; (b) the semi-circular wall of the inner tube is more readily deformable than the circular wall of the outer tube; (c) at the top end of the inner tube, the semi-circular wall thickens into a rigid first fully circular shoulder section that terminates in a first neck portion having an outer diameter and an inner diameter, said first neck portion having an opening that communicates with the first cavity of the inner tube; (d) at the top end of the outer tube, the circular wall thickens into a rigid second fully circular shoulder section that terminates in a second neck portion having an outer diameter and an inner diameter, said second neck portion having an opening that communicates with the second cavity of the outer tube; (e) the outer diameter of the first neck portion of the inner tube is greater than the inner diameter of the second neck portion of the outer tube such that the first neck portion of the inner tube press-fits or friction-fits into the second neck portion of the outer tube, thereby causing the inner tube to be held firmly in place within the outer tube; (f) the flat wall of the inner tube constitutes a spine that has: (i) a thickness greater than the thickness of the semi-circular wall of the inner tube; (ii) a width substantially equal to an internal diameter of the outer tube below the second shoulder of the outer tube; (iii) a width which follows a cross-sectional width of the first shoulder and neck potions of the inner tube; and (iv) a length which is substantially equal to the length of the container, thereby dividing both the inner and outer compartments into two substantially equal portions.
