ABSTRACT:
A device seals an open end of monodose containers, which have already been filled with liquid or viscous solutions without need to trim the sealed ends, comprising grippers with jaws approximately shaped like a comb. In a first version, the jaws have square prongs counter opposed when the gripper is closed and a comb-shaped head inserted between the prongs of the jaws prevents formation of irregular edges at the ends which would otherwise require trimming. In a second version, one of the jaws has prongs which insert into corresponding recesses in the other jaw, while a flat-faced head closes the prongs of the gripper to prevent formation of irregular upper edges.
