An adapter for positioning between a filling head and an aerosol-type dispenser having a separate product container. The adapter is an annular member having the upper surface tapered with a taper complementary to the taper of the lower surface of the filling head and the lower surface tapered with a taper complementary to the taper of the upper surface of the dispenser. The axial dimension of the annular member at the inner periphery thereof is sufficient to space the filling head from the dispenser. The annular member has at least one air escape passage extending from the inner periphery thereof to the outer periphery thereof to which vacuum means can be connected to assist in air withdrawal as the product container is filled.
