Abstract
Abstract A container lid, especially useful in the pharmaceutical testing industry, having a pair of overlapping lid elements which are rotatable with respect to one another. The lid elements have matching apertures which allow the insertion of testing apparatus into the container covered by the lid without the necessity of removing the lid. The rotatable elements may be positioned tightly around the testing apparatus to reduce the possibility of evaporative loss and of contamination of the testing medium.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
A multi-piece container lid comprising: a circular upper lid element and a circular lower lid element each having a central axis, the lid elements each having a planar upper surface and a planar lower surface and wherein the lid elements are mounted in overlapping juxtaposed axial alignment with one another, the lower lid element being matingly engaged with the upper lid element and being mounted thereto to effect relative circumferential movement between the respective lid elements, means mounted in cooperative engagement between the lower lid element and the upper lid element to effect relative movement between the lid elements, the upper element having a peripheral down turned edge, the downturned edge having a re-entrant lip projecting inwardly toward the center of the upper lid element and wherein the lip extends approximately parallel to the lower surface of the upper lid element, the upper lid element having a slot formed through the peripheral downturned edge and the re-entrant lip, and extending inwardly toward the axis of the upper lid element.
Claim 2
Dependent Claim
169 words
A multi-piece container lid comprising: a circular upper lid element and a circular lower lid element each having a central axis, the lid elements each having a planar upper surface and a planar lower surface and wherein the lid elements are mounted in overlapping juxtaposed axial alignment with one another, the lower lid element being matingly engaged with the upper lid element and being mounted thereto to effect relative circumferential movement between the respective lid elements, means mounted in cooperative engagement between the lower lid element and the upper lid element to effect relative movement between the lid elements, the upper element having a peripheral down turned edge, the downturned edge having a re-entrant lip projecting inwardly toward the center of the upper lid element and wherein the lip extends approximately parallel to the lower surface of the upper lid element, the upper lid element having a slot formed through the peripheral downturned edge and the re-entrant lip, and extending inwardly toward the axis of the upper lid element.
Claim 3
Dependent Claim
29 words
A multi-piece container lid as claimed in claim 1 wherein the lower lid element has a peripheral edge located inwardly of the re-entrant lip of the upper lid element.
Claim 4
Dependent Claim
49 words
A multi-piece container lid as claimed in claim 2 comprising an outwardly projecting engagement lip forming an extension of the upper planar surface of the lower lid element, the engagement lip having a configuration to enable the engagement lip to fit within the slot of the upper lid element.
Claim 5
Dependent Claim
34 words
A multi-piece container lid as claimed in claim 3 wherein each of the lid elements have a slot radially extending from the axis of the respective lid element to the farthest peripheral edge thereof.
Claim 6
Dependent Claim
39 words
A multi-piece container lid as claimed in claim 4 wherein the upper lid element has an arcuate slot therein, the relative movement means projecting through the upper lid element arcuate slot and being fixed to the lower lid element.
Claim 7
Dependent Claim
66 words
A multi-piece container lid as claimed in claim 4 wherein one of the lid elements has an aperture therein located between the axis of the lid element and the farthest peripheral edge thereof, the other lid element having an arcuate slot located between the axis of the lid element and the farthest peripheral edge thereof, the aperture and the arcuate slot being juxtaposed with one another.
