Abstract: This relates to the provision of a vacuum identifying button of a conventional closure for containers with encapsulated microcapsules containing a suitable dye. While the button is in its depressed, concave configuration, a coating surrounding the microcapsules is cured and caused to bond to the microcapsules. When the button everts to project upwardly and have a convex configuration, the coating is tensioned causing the microcapsules to rupture and release the color forming dye materials thereof. If desired, the evidence of button flipping or tampering may merely be in the form of a colored area, such as a stripe. In a modification, the effected colored areas may be in a design to present a warning or message. For example, a simple message such as "OPENED" may be effected.
