ABSTRACT OF THE DISCLOSURE In a dispenser of the kind used for dispensing a fluid by applying pressure on a container, a bag assembly is provided with a tubular pleated bag, a ribbed coating being formed over the bag by dipping. After the bag is filled to capacity with a fluid, pressure is maintained on the bag by an energy tube. As the fluid from the bag is selectively discharged causing the bag to collapse, the bag folds along the pleats under the influence of the coating until substantially all of the fluid has been removed. The assembly is made by forming the bag into a pleated shape and then dipping the bag into a suitable material to form a coating with beads. After the coating dries the bag is inserted into the energy tube.
