  "original_title": "Packaging of chip-type snack food products",
  "summary": "A 1970 patent by Procter and Gamble describing the precise method for stacking uniform, saddle-shaped potato chips into a cylindrical container to prevent breakage.",
  "what_it_does": "The patent describes a method for packaging snack chips that are uniform in shape, specifically the hyperbolic paraboloid or saddle shape. By creating chips that nest perfectly within one another, the invention allows them to be stacked in a column rather than poured loosely into a bag. This stacking mechanism is designed to minimize air space and prevent the chips from fracturing during shipping and storage, as the nested structure provides structural integrity to the entire stack.",
  "what_it_does_not_cover": [
    "Does not cover standard potato chips that are irregular in shape or size.",
    "Does not cover flexible packaging methods like traditional plastic or foil bags.",
    "Does not cover the specific chemical recipe or dough composition used to create the chips.",
    "Does not cover non-cylindrical container shapes that do not support the nested stack."
