Closure device for container

A closure device for a container, the container defining a neck and an annular flange positioned along an exterior surface of the neck, the closure device comprising:

• a cap body;
• a tamper evidence band that is positioned below the annular flange when the closure device is positioned on the neck of the container;
• a tongue extending from the cap body towards the tamper evidence band, wherein a root end of the tongue is positioned inwardly of a rim of the cap body towards a closed end of the cap body;
• and
• a first leash and a second leash positioned on either side of the tongue and connecting the cap body to the tamper evidence band, the first leash and the second leash allowing the cap body to be removed from the neck of the container while remaining attached to the tamper evidence band, wherein when the cap body is actuated to a fully open position:
• the first leash and the second leash act as a torsion bar such that the tongue exerts a force against the neck of the container for retaining the cap body in the fully open position;
• the first leash and the second leash each comprise a first portion and a second portion, with the second portion being directly connected to the first portion, wherein when the closure device is in a fully closed position an entire bottom edge of the first portion lies in a plane substantially parallel to an upper edge of the tamper evidence band, and the second portion extends at an angle from the first portion into the cap body towards the root end of the tongue such that the second portion is positioned only at or above the entire bottom edge of the first portion.
