Abstract: A method and apparatus for covering and identifying a container utilizing a thin film material and a frame. The thin film material covers a through hole in the frame and has a perforation that defines an outer detaching surface an inner covering surface commensurate with the container opening. The method comprises the steps of attaching the thin film material to a frame having the through hole; disposing the frame onto an open top surface of the container; depressing a portion of the frame to detach the thin-film from the frame along the perforation and further sliding the frame coaxially to circumscribe the base of the container where it identifies information about the container.

Abstract: A cup assembly for holding a sample to be analyzed spectrochemically, including a sample cell having a generally cylindrical wall longitudinally extending between a first end and a second end thereof and a sleeve having a generally cylindrical wall longitudinally extending between a first end and a second end thereof, and a plurality of projections longitudinally extending from the first end of the sleeve wall. When a substantially planar film is interposed between the sample cell and the sleeve, and the first end of the sample cell is inserted into the first end of the sleeve, the film is retained between the sample cell and the annular sleeve; and the longitudinal projections are positioned to perforate the film when the film is pulled against the longitudinal projections.

Abstract: A sample cup for retaining a sample material to be subjected to an x-ray spectrochemical analysis. The sample cup comprises a cell body of a cylindrical configuration having an open top end and an open bottom end and defining a hollow between the two open ends, the open top end having an outer wall and an inner wall encircling the open top end. The outer wall and the inner wall extend axially and are positioned in concentric relationship with one another and form a reservoir space therebetween.
