Have you ever flipped over a Tupperware lid and spotted a tiny icon of a fork and cup etched into the plastic? It might seem like a random design detail — but it’s actually one of the most important symbols on your kitchenware.
Let’s decode it.
The Fork and Cup Icon Explained
That little image of a fork and wine glass means your container is safe for food contact. In simple terms, it’s been tested and approved to store food and beverages without leaching harmful chemicals into what you eat or drink.
This mark isn’t just decorative — it’s an international symbol recognized under both European and U.S. food safety regulations. It ensures that the plastic won’t release toxins, alter flavors, or react with food during normal use.
If you don’t see the fork-and-cup symbol on a plastic container, don’t panic. It doesn’t automatically mean it’s unsafe — but it might not be designed for long-term food use. In that case, it’s best to use it for non-edible storage (like craft supplies, screws, or office items).
Why the Symbol Matters
Plastic safety is a big deal. Over time, consumers have become more aware of chemical leaching — when certain plastics release small amounts of substances into food, especially under heat or extreme cold.
The fork and cup symbol guarantees that the container’s material has passed strict safety tests. It won’t change your food’s taste or smell and is stable under normal kitchen conditions.
That’s why you’ll see it not only on Tupperware, but also on reusable water bottles, lunch boxes, and utensils.
If your container has this mark, you can confidently use it for:
Leftovers and meal prep
Packing lunches
Freezing soups or sauces
Storing dry pantry goods
