EVANSVILLE, Ind. — A container cap that does not “back off”--or loosen by itself--has been developed by Sunbeam Corp., for leakproof packaging of liquids.
Caps with screw threads tend to “back off” and become loose. They are unsuitable for liquid-proof seals, Robert Lehman of Sumbeam said.
Snap caps have been used mostly with dry products such as aspirin because most people would not have the strenght to open a snap cap that was tight enough to be leakproof, he said.
