Metal Tube Wringer, Gill Mechanical, USA
The Larry David of 1970s hardware inventors, John Gill fueled his brilliance with petty annoyances to create a masterwork of his time.
Albeit rare, he was triggered to invention by discarded tubes still 5% full. Paint, ointment, toothpaste, adhesive, and more– the last squeeze wasted.
He decided to act. Borrowing "empty" tubes of paint from local children, he engineered and tested this delightful machinery.
When the tomato paste is nearly done you will jump like an elf to grab your Crimper. When it's down to a drop of Sensodyne you will scream as you wring it smoothly onto your brush.
Though rarely used, it turns the end of a tube into a special occasion. Great gift. Children love it.
