Abstract
A dispensing container for cream-like fluids includes a cylindrical body having upper and lower closures. The lower closure is a piston which moves toward the upper closure as the fluid is dispensed from the container. Normally, the container is filled with fluid and then closed with the lower closure. The lower closure or piston is provided with a hole which permits air between the fluid and piston to escape when the lower piston is mounted in the container. The hole is sealed with a disc located at the lower inside portion of the container. The container can advantageously and rapidly reduce the quantity of air remaining in the container thereby reducing deterioration of the fluid due to contact with air.
