-10- VACUUM-TAMPER INDICATING BUTTON FOR SMALLER DIAMETER CAPS AND THE LIKE ABSTRACT OF THE DISCLOSURE 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 27mm to 43mm. 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 tamper- ing. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application. * * * * *
