Requiring just four quick twists of the wrist to open the four tamper-evident locking tabs at the corners, the package was born out of the consumer’s desire for convenience. After also removing an inner foil membrane, the product was microwaved in seconds and served without needing to scoop it onto another plate.
A quick Google search (pwgo.to/835) makes it appear that, 20 years later, the product and package are still going strong, though apparently the twist-off tabs have bitten the dust.
