Abstract
A sliding seal for the closure of a container. The closure is of the type having a portion fixed to the container and a portion hingedly secured thereto for permitting access to the interior of the container. The seal has a first segment secured to the fixed portion of the closure and a second segment extending from the first and slidably connected to the pivotal portion of the closure by means of a post secured to the pivotal portion and extending through a slot formed in the second segment. The post is capped by a washer or the like to retain the second seal segment about the post. The seal is otherwise unattached to the pivotal portion of the closure, and therefore slides relative to the pivotal portion to prevent stretching of the seal as the closure is opened.
