Abstract
This disclosure relates to a tamper-indicating press-on, pull-off closure for maintaning pressure in a container whereby the closure and container provide a package which may be readily opened by a consumer without the use of tools and without the creation of dangerous sharp edges. This closure includes a cap and a unique cap liner which fits within the cap and is formed integral with a pull ring for removal of the cap from a container. A plurality of severable tamper-indicating webs are formed between the pull ring and the cap liner and sever upon actuation of the ring pull to indicate tampering with the package. The cap incorporates a plurality of scores in its skirt portion which fracture when the pull ring is actuated to thereby release the cap from engagement with the container.
