Quick answer

To use the Tefal Masterseal Rectangular 2.2L container, simply press the lid down evenly until you hear a click, then stack it with other containers to save space. The smart sealing system keeps food fresh without extra locks.

Why the rectangular shape matters

The rectangular design isn't just for looks. It allows you to stack multiple containers neatly in your fridge or pantry, making the most of every inch of shelf space. This is especially useful when storing meal prep or leftovers alongside other Masterseal containers.

What the Masterseal system does

The Masterseal system uses a flexible silicone gasket inside the lid to create an airtight seal. When you press down, the gasket compresses against the rim of the container, locking out air and moisture. This helps keep food fresher for longer compared to containers without a seal.

Steps to use the Tefal Masterseal Rectangular 2.2L container

  1. Fill the container: Place your food—leftovers, meal prep, or bulk ingredients—inside the 2.2L container. Leave a little space at the top to allow the lid to seal properly. Overfilling can prevent the lid from clicking shut and breaking the seal.
  2. Align the lid: Position the lid squarely on top of the container. Make sure the silicone gasket sits evenly against the rim all the way around. A misaligned lid may not seal, letting air in and reducing freshness.
  3. Press down to seal: Press firmly on the center of the lid until you hear a click. The Masterseal system will lock the lid in place, creating an airtight seal. If you don't hear a click, press again or check that the lid is aligned correctly.
  4. Stack and store: Place the sealed container in the fridge or pantry. Thanks to the rectangular shape, you can stack multiple containers on top of each other without them sliding off. Avoid stacking containers when they are still warm from hot food; let them cool first to prevent condensation.
  5. Open the container: To open, lift the tab on the lid gently. The seal releases easily without needing to pry or twist. Never use a knife or sharp object to open the lid—it can damage the gasket and break the seal.
