Abstract
A holder is shown for empty beverage cans which are to be tested for the abrasion resistance of coatings on the cans. In one embodiment, the holder is formed with an elastomer shell which is received in an empty can. An expander is inserted in a longitudinal opening in the shell and is rotated to engage cam surfaces on both the shell and holder thereby expanding the shell into contact with the empty can. The pressure exerted by the expanded shell simulates that of the contents of a beverage can. In a second embodiment the elastomer shell has a conical opening which receives a similarly conically shaped expander which expands the shell in all directions as it is forced longitudinally into the shell. A strap holds three cans and their holders together by engaging projections into shaped recesses in the tops of the expanders.
