Tupperware is a household name across the globe, known for its reliable and reusable food storage containers. While many of us use Tupperware products every day, few actually take the time to look closely at the small symbols printed on the bottom of their cups, bowls, or containers. These seemingly minor markings hold important information — not just for your safety, but also for better product use, maintenance, and even recycling.
If you’ve ever flipped over a Tupperware cup and seen a triangle, number, fork and cup symbol, or dishwasher icon, you’ve probably wondered: What do these actually mean? This article breaks it all down in a simple, easy-to-understand way so you can make informed choices about how you use and care for your Tupperware cups.
🌀 Why the Symbols on Tupperware Matter
Symbols on the bottom of Tupperware products (including cups) are international standard icons designed to communicate information about:
- Material type
- Food safety
- Reusability
- Microwave/dishwasher compatibility
- Recycling category
They’re not decorative — they’re functional. Understanding what each one means helps you:
- Use the cup safely (e.g., microwave or not)
- Wash it correctly (hand wash vs dishwasher)
- Dispose of it properly (recyclable or not)
- Know what kind of plastic you’re using
