Chances are that you've thrown away many package saver
s in your life and never knew what to call them. I didn't know what to call them, either, until tonight.
The package saver is the patented and nearly ubiquitous gadget that keeps the box lid from smushing down into your pizza.
Pizza lovers everywhere can thank Carmela Vitale, whose patent (US 4498586) describes "a temperature resistant molded plastic device ... for use in boxes or packages such as pizza boxes where there is a tendency of large cover portions to sag downwardly to damage the soft pizza or other packaged products."
Brava, Ms. Vitale.
