ABSTRACT:
A closure system for a container having a closure body with a hingedly connected closure lid. The closure body has an end wall and a cylindrical skirt with internal threads for screwing the closure system onto the container. The closure lid has at least one integrally molded projection extending from its cylindrical skirt. The projection engages the closure body end wall when it is desired to dispense material from the container. This projection is rigid enough to prevent the closure lid from interfering with the dispensing of the materials from the container yet is resilient enough to fold under the closure lid when the closure system is in the closed mode.
