Avoiding bent lids

By Staff -- Plant Engineering, 9/1/1999

Problem: After repeatedly opening and closing a can that has a pry-off lid (such as plumber's putty or wood putty), the lid becomes dented and deformed and allows air to dry out the

contents.

Solution: After use, don't hammer the lid shut. Press the lid onto the can by hand, and then turn the can upside down and hit a flat surface such as a workbench, floor, or lumber. The lid is evenly sealed with one hit. (Ed. note -- A variation is the method used by painters: Place the can on the floor and press down on the lid with the sole of one shoe for an even seal.)
