A cap is provided for a laboratory vessel. The cap includes a lid that can be rotated relative to the laboratory vessel from a closed position to an open position. The lid includes at least one tab dimensioned and disposed for receiving manual digital pressure for opening and/or closing the lid. The tab is in an offset position to prevent a thumb or forefinger from passing over and in contact with the opening to the vessel. Additionally, the lid includes a shield inwardly from the tab for further preventing contact between a finger and the open top of the vessel.

1. A cap for mounting to an open top of a laboratory container, said cap comprising: a cap body comprising a side wall, having an outer surface and an inner surface, and a top wall, having an outer surface and an inner surface, the top wall defining an opening, the inner surface of the side wall comprising threaded features, the outer surface of the top wall comprising a sealing surface; and,a lid hingedly connected to the outer surface of the side wall of the cap body, the lid being rotatable about an axis of rotation relative to the cap body between a closed position and an open position, the lid comprising: a shield configured to at least partially cover the side wall of the cap body when the lid is in the closed position, the shield comprising an outer surface and an inner surface, the shield comprising at least one protrusion extending outwardly from the outer surface of the shield to provide an engagement surface for a thumb or forefinger during opening of the lid;a top wall having an outer surface and an inner surface; and,a skirt extending from said inner surface of the top wall of the lid,wherein the skirt is spaced from the inner surface of the shield, said skirt dimensioned for telescoping into the opening defined by the top wall of the cap body when the lid is in the closed position, the inner surface of the top wall of the lid engaging with the sealing surface of the top wall of the cap body when the lid is in the closed position. 2. The cap of claim 1, wherein said cap is unitarily formed from resin. 3. The cap of claim 1, wherein said shield extends from the top wall of the lid. 4. The cap of claim 1, wherein the axis of rotation is located spaced radially outwardly from the outer surface of said side wall of said cap body. 5. The cap of claim 1, wherein first and second short sections extend from said top wall of said lid, said first and second short sections each extending less distance from said top wall of said lid than said shield. 6. The cap of claim 5, wherein said first short section extends from a first end of said shield, and said second short section extends from a second end of said shield. 7. The cap of claim 1, wherein said shield is substantially cylindrically generated about a longitudinal axis aligned substantially normal to and spaced from said axis of rotation defined by said hinge. 8. The cap of claim 7, wherein said shield extends through an arc of approximately 180° about said longitudinal axis. 9. The cap of claim 8, wherein said shield is spaced symmetrically from said hinge.
