A container having a damage-resistant finish ring and an opening sealable by a closure member that is removable by a hook-type opener is disclosed. The damage-resistant finish ring has a locking ring with a convex outer surface.

An apparatus and method for measuring and analyzing light transmittance through containers is provided. A system is disclosed in which a light probe is insertable into a container in order to measure light transmittance through portions of the container wall. The light probe is connected to a spectrophotometer which analyzes the light transmitted through the container wall. Light transmittance is measured over a series of light wavelengths in order to accurately predict the ability of the container to protect its contents from the detrimental effects of light. In addition, the container may be tested for light transmittance at several locations. The measured light transmittance of each location may be weighted differently in order to compensate for the anticipated exposure to light of the particular location. Also provided is a method for monitoring and controlling a container manufacturing process in which containers may be analyzed for light transmittance and the process adjusted accordingly depending upon the analysis.

A can end for a two-piece beverage can including a score panel defined by an arcuate score line which comprises a score groove and a score residual portion. In order to control the opening speed of the score panel, the thickness of the score residual is varied along the score line. A thickened score residual area or areas may generally be located opposite the rivet area of the can end. The remainder of the score residual may be formed having a relatively smaller thickness, thus allowing opening of the end to be accomplished without the need for excessive force.
