The present invention provides an improved, leak proof, air tight, cost-effective, plastic liquid specimen container device and methods of use, comprised of a container, a lid, a lid groove containing a gasket therein that is configured to cover and tighten over the rim of the container, a lid flange, and a thin hook in the container containing a second gasket that is compressed by the lid flange when the lid is closed over the container. The improved container device of the present invention thus provides two, independent, internal seals that protect the liquid contents therein for extended periods of time, even if the plastic undergoes deformation, during transport, especially air transport, and under varying temperature and atmospheric pressure.

1. A leak proof, air tight plastic specimen container device, comprising: a container comprising a circumferential side wall, said side wall having an inner surface and an outer surface and an upper rim, said inner surface defining an interior opening therein for holding a liquid sample, said side wall projecting downwardly from said upper rim, an L-shaped hook continuous with and protruding from the inner surface of the circumferential side wall and located downwardly from said upper rim, said hook having an upper surface containing a container gasket which fits atop the entire upper surface of the hook; a plurality of external screw threads projecting downwardly from the upper rim on the outer surface of the circumferential side wall, and a bottom; anda lid comprising an outer side and an inner side and a peripheral edge, a plurality of indentations projecting downwardly from the outer side of the peripheral edge, a plurality of internal screw threads on the peripheral edge of the inner side, an annular groove on the inner side of the lid adjacent to the peripheral edge having a lid gasket therein, and an annular, straight lid flange on the inner side adjacent to the annular groove, said lid configured to rotatably screw on to the outside of the container by engagement of the internal screw threads of the lid with the external screw threads of the container and to close the opening of the container by rotation of the lid in a screw-type fashion until resistance to the rotation is encountered, wherein the lid gasket in the annular groove is configured to mate with and be compressed atop the upper rim of the container to form a tight seal, wherein the annular straight lid flange is configured to insert into and atop the entire upper surface of the hook so that the container gasket therein is compressed under the annular straight lid flange to form a second, separate tight seal, wherein when the container gasket is compressed, the straight lid flange, the upper surface of the container hook and the container gasket all have substantially the same width. 2. The plastic container device of claim 1, wherein when the lid is rotatably screwed on to the outside of the container, the two separate seals prevent any leakage of the liquid sample from the interior of the container and any air seepage into or out of the interior of the container. 3. The plastic container device of claim 1, wherein the volume capacity of the contents of the container ranges from 500 ml down to 40 ml. 4. The plastic container device of claim 1, wherein the lid gasket and the container gasket have the same diameter. 5. The plastic container device of claim 1, wherein the container gasket has a smaller diameter than the lid gasket.
