ABSTRACT:
A method and apparatus for forming stackable plastic battery containers having stacking grooves is disclosed. A hot tip injection nozzle is centrally located within a raised section of a die thereby forming a depression within the stacking grooves. The nozzle has a gate offset from the nozzle center line. In this manner, the gate remnant formed by the gate offset does not interfere with the stacking of the containers.
