Abstract
This relates to a closure cap for containers wherein the end wall of the closure cap and more particularly an end panel thereof may be subjected to a vacuum which will determine the condition within the container. The closure cap involved is of a small diameter and is specifically intended for use in conjunction with neck finishes having diameters ranging from 27 mm to 43 mm. The end panel of the closure cap is of a specific configuration so that a small diameter central portion in the form of a button will evert under the existing vacuum conditions so as to present a substantially plain end panel when the vacuum condition exists within the container and which will show a popped up button when the vacuum has been relieved. The button will be indicative of product condition or possible tampering.
