Crown cap bottle opener - has thin hook for insertion under corrugation and end shaped to match top of cap

摘要

A crown cap bottle opener is made from flat strip (1) with an opening hook (8) one end and the other end with a hole (5) at that end for hanging up. The hook is rounded, and made sufficiently small to be inserted between the corrugated skirt of the cap and the neck of the bottle. This hook is formed by making an approximately circular cut-out (4) near the end. The remainder of this end has acontact face with a rounded step (9) shaped to match the contour of the top corner of the bottle cap.
