Abstract:

A method for sealing the open end of two compartment containers which are filled through an opening in the lower terminal end of each compartment. The method consists of placing a steel platen between the compartments at the lower end terminal edges of each compartment so that the terminal edges confront the opposing side faces of the platen. The lower terminal edges are then heated and a pair of dies are activated towards and away from one another to apply pressure to the lower terminal edges to seal the edges against the platen.
