  • Method for restoring dented areas in bottle neck finish
    Patent number: 4522770
    Abstract: This relates to the removal of indentations in the sealing surfaces of plastic bottles, particularly blow molded bottles. The neck finish of each bottle, as it moves along a discharge conveyor from a blow molding machine, is heated to a temperature approaching the glass transition temperature of the plastic material, at which temperature the memory of the plastic material begins to induce slight flow and wherein the indentations are eliminated by the flow of the plastic material of the sealing surface.
