ABSTRACT:
A watertight hinge closure for a dispensing container. The closure has a lid with a solid unitary one-piece hinge which snaps shut onto a cap body integrally formed therewith. The lid and hinge are formed to leave a minimal space between the lid, the hinge and the cap body when the closure is in the shut position. The top of the cap body has a raised portion which is angled toward the snap fit portion of the lid opposite the hinge to prevent seepage and to avoid stagnant areas which could cause contamination.
