1. A closure device for a container, the container having a neck including an annular flange along an exterior surface of the neck, the closure device comprising:
a cap body;
a tamper evident (TE) band, the TE band defined such that, when assembled onto the container, the TE band is positioned below the annular flange for cooperation therewith;
a first hinge and a second hinge defined on the cap body;
a leash interconnecting the first hinge and the second hinge to the TE band such that a segment of the leash spans between the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash;
a tongue protruding from the cap body between the first hinge and the second hinge;
when the cap body is actuated from a closed configuration relative to the neck to a fully open position:
the leash is configured to retain the cap body to the TE band;
an interaction of the tongue with the leash at an upper portion of the annular flange is configured to retain the cap body in the fully open position.
