Abstract: An article assembly apparatus and method employs rotary pick and place technology to deposit one component of an apparatus within another at a relatively high rate of speed. A substantially disk-shaped component is inserted within a substantially cylindrical component with a relatively tight fit between the two. The substantially disk-shaped component is carried at a fixed, predetermined angle, relative to a radius of a rotating wheel carrying the component, permitting the smooth placement and depositing of the substantially cylindrical component within the substantially cylindrical component. The substantially disk-shaped component may comprise a piston and the substantially cylindrical component may comprise a body of a bottom filled airless container undergoing assembly following the placement of a substance to be dispensed within the body.
