Abstract
The invention relates to the combination of a closure and of a container, the closure displaying a peripheral depending skirt while the container displays, along the walls thereof, a continuous peripheral flange receiving, on the top face thereof, the lower edge of the closure skirt. The connection of the flange at each corner is weakened by the presence of a series of gaps to render the flange at those areas breakable to thereby provide a visual indication of removal of the closure, whether it be authorized or unauthorized.
