A method for delivering liquids is disclosed wherein a quantity of the liquid is provided within a cell within a cassette. The cassette is received within a sleeve having an open end. A flap at the open end of the sleeve extends inwardly through the open end between the sleeve and cassette to abut a lip on the cassette and hold the cassette therein. Impingement of the flap pushes the flap away from the lip to allow the cassette to move out of the sleeve. A label mounted within the sleeve rotates between a viewable position where it is visible through a window in the sleeve and a retracted position away from the window. Extraction and reinsertion of the cassette into the sleeve moves the label from the viewable to the nonviewable position.

[ What is claimed is:] [1.] A cassette assembly comprising:a cassette having a first side and a first end;a protective sleeve containing the cassette, the sleeve comprising a first side and a first end, the first side having a window aperture therethrough; anda label member within the sleeve having indicia thereon, the label member being rotatably mounted about a first hinge adjacent the window aperture, the label member having:a first position of rotation about the first hinge with the cassette within the sleeve wherein the label indicia is in registry with said window aperture whereby the label indicia is visible therethrough, anda second position of rotation about the first hinge with the cassette within the sleeve wherein the label indicia is out of registry with said window whereby the label indicia is not visible through the window aperture; andthe first hinge being oriented with respect to the sleeve first end so that when the cassette is inserted through the first end, the cassette abuts the label member and urges it about the hinge into the second position,whereby extraction of the cassette from the sleeve and reinsertion of the cassette into the sleeve moves the label member from the first position to the second position to indicate that the cassette has been at least once extracted from the sleeve. [13.] A method for delivering a cassette to a device comprising the steps of:placing the cassette within a protective sleeve having an open end;hingably mounting a label member with an indicia thereon within the sleeve;rotating the label member into a first position with the indicia visible through a window aperture through the sleeve;abutting the label member with the cassette when the cassette is within the sleeve to hold the label member in the first position;sliding the cassette out of the sleeve through its open end;processing the cassette in the device; andsliding the cassette back into the sleeve through its open end and abutting the label member thereby to swing the label member to a second position with the indicia out of register with the window aperture and not visible therethrough. A method according to claim 13 wherein the step of processing the cassette comprises removing a substance from the cassette. A method according to claim 13 wherein the steps of sliding the cassette out of and back into the sleeve through its open end are performed by a machine. A method according to claim 15 and further comprising the steps of reading the label indicia with a sensor prior to the step of processing the cassette in the device. A method according to claim 16 and wherein the steps of reading the label indicia, sliding the cassette out of the sleeve, processing the cassette and sliding the cassette back into the sleeve are controlled by an automatic control unit. A method according to clam 17 wherein the automatic control unit is programmed to not perform the steps of processing the cassette if the sensor fails to first read the presence of the label indicia. A method according to clam 17 wherein the automatic control unit is programmed to not perform the steps of processing the cassette if the label indicia indicates that the cassette is not proper.
