Screw cap for plastic containers, in particular tubes or bottles

摘要

The tube screw cap (1) has on a plate (3) grooves (N) and teeth (Z) which allow two or more screw caps to be fitted together. Projections (10) are arranged on the circumference of a circle whose radius (r) corresponds to that of the threaded part (2) on the screw cap so that the screw caps can also be stacked in a stable manner. A playset of screw caps comprises a plate provided with through-holes, the diameter of the hole corresponding to the outside diameter of the threaded part on the screw cap. <IMAGE>
