ABSTRACT:
The container comprises an open-topped cylindrical container body having a pair of tabs on the upper end of the outside, and a removable cylindrical resilient cap, having a sidewall with vertical grooves on the inside matching the tabs in location, but closer together diametrically than are the tabs. The cap is deformable to accommodate the tabs. The sidewall also has a pair of about horizontal arcuate grooves extending from the vertical grooves larger diametrically than the vertical grooves to receive the tabs. The horizontal grooves may narrow as they diverge from the vertical grooves. The cap cannot be removed from the container body without first rotating the cap to free the wedged tabs, then ovaling the cap to allow the cap to be rotated to a position where the vertical grooves and tabs are aligned, whereupon the cap can be lifted off the container body.
