ABSTRACT:
A dispensing type container wherein a fluid product is dispensed under pressure from the container in the absence of special charging gases such as Freon and the like which are customarily utilized and which have been found to be objectionable. The container is charged with air under pressure from the atmosphere and includes a built-in cylinder which is associated with a separately formed and mounted piston. When the container is to be charged for dispensing the product, it is merely placed on the piston and reciprocated several times to pump air thereinto under pressure. The piston is reusable.
