ABSTRACT:
A container for storing and dispensing various fluid substances with a cylindrical housing that is divided into two chambers by a partition wall positioned along the longitudinal axis of the housing. Each chamber includes a closed end with an outlet opening and an open opposite end. A semicircular shaped plunger fits in the chamber that is slidably displaceable towards the outlet opening. A first portion of each plunger is formed with a chamber facing the fluid substance stored in the chamber. An outside edge of the first portion forms a lip seal between the plunger and the interior side wall of the chamber. On the opposite side of the plunger a second portion includes several ribs that are adapted to receive a pressure plate against which an operating pressure is applied using a known pressure device. Each outlet opening is hermetically sealed by a plug seal held in place by a collar nut.
