ABSTRACT:
The invention is an improved cap for a collapsible tube, particularly a tube having tamper evident means as is used on tubes having eye medications. The cap has a flexible substantially cylindrical wall which can be squeezed into an elliptical shape to permit the user to exert substantial force, by means of a "thumb screw" effect, to unscrew the cap from the tube.
