A can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

The present invention relates to a security closure system and devices for containers, which can be used in any type of container and can be validated by means of simple sight and touch, thereby being tamper-resistant and preventing any adulteration by means of the non-authorised re-use of the original container. The system and devices are preferably used in containers made from vitreous materials such as ceramics, plastics and thermoplastics, owing to the properties of stiffness. The devices of the invention can be used for any product and any type of container, such as bottles for alcoholic and non-alcoholic drinks, containers for cosmetics, perfumes, drugs, food and valuable items such as watches, electronics or fine jewelry.

A container cap assembly provides a tamper-evident component for detecting cap integrity on a container includes one or more elongate bridges connecting a tamper-evident ring to a cap. The cap assembly also provides radially-extending links on the cap and the tamper-evident ring to help protect the integrity of the bridges as the cap assembly is applied to a container.
