  "title": "How the Crown Cork Bottle Cap Changed Soda and Beer",
  "original_title": "Bottle-sealing device",
  "summary": "William Painter's 1892 invention of the crown cork bottle cap, a simple metal disc with a crimped edge that provided an airtight, disposable seal for carbonated beverages.",
  "what_it_does": "The device functions by using a metal cap with a corrugated or crimped edge that is pressed over the rim of a glass bottle. A small gasket inside the cap creates a hermetic seal against the bottle's lip. This design allows the cap to withstand the internal pressure of carbonated drinks like beer or soda without leaking or popping off prematurely. It is designed to be easily removed using a separate opener, rendering the cap single-use.",
  "what_it_does_not_cover": [
    "Does not cover screw-top bottle closures.",
    "Does not cover cork-based stoppers that rely on friction inside the bottle neck.",
    "Does not cover re-sealable caps or flip-top mechanisms.",
    "Does not cover the glass bottle design itself."
