  • Process for making filter cups
    Patent number: 4235160
    Abstract: A percolator having a cylindrical basket concentric with a wand is provided with a filter paper cup having an annular bottom coextensive with the bottom of the basket and having upstanding fluted sides. The filter cups are formed by cutting and forming them into a nest of cups having an imperforate bottom, transferring the nest of cups to a frusto-conical die having a circular top commensurate with the circular bottom of the filter cups, a central die-hole, and outwardly and downwardly flaring sides corresponding to the natural outward flare of the nested cups, and punching an axial hole in said nested cups while on said die by means of a punch complementary with said die-hole.

  • Filter paper cup for a percolator and process for making the same
    Patent number: 4094234
    Abstract: A percolator having a cylindrical basket concentric with a wand is provided with a filter paper cup having an annular bottom coextensive with the bottom of the basket and having upstanding fluted sides, characterized in that the flutes are steam and heat set. The filter cups are formed by cutting and forming them into a nest of cups having an imporforate bottom, heating the nested cups, exposing them to moist steam, heating to dry the steamed cups, and cooling them to ambient temperature, transferring the nest of cups to a frusto-conical die having a circular top commensurate with the circular bottom of the filter cups, a central die-hole, and outwardly and downwardly flaring sides corresponding to the natural outward flare of the nested cups, and punching an axial hole in said nested cups while on said die by means of a punch complementary with said die-hole.
