Setup
Before first use, and after each use, thoroughly clean all components of the food jar. This includes the main body, lid, and spork. Refer to the "Maintenance" section for detailed cleaning instructions.
Pre-heating or Pre-cooling (Optional)
- For hot contents: Fill the food jar with hot water (not boiling) and let it stand for 5-10 minutes. Empty the water before adding your food.
- For cold contents: Fill the food jar with cold water or ice water and let it stand for 5-10 minutes. Empty the water before adding your food.
This step helps to maximize the temperature retention performance of the food jar.
Operating Instructions
Filling the Food Jar
- Ensure the food jar is clean and, if desired, pre-heated or pre-cooled.
- Carefully pour or place your food into the wide-mouth opening. Do not overfill; leave some space for the lid.
- For best temperature retention, fill the jar as completely as possible with hot or cold food.
Securing the Lid
- Place the lid onto the food jar.
- Turn the lid clockwise until it is securely tightened. This ensures a leakproof seal.

Troubleshooting
Lid Not Sealing Properly
- Ensure the silicone gasket inside the lid is correctly seated and free from food debris.
- Check for any damage to the lid or the rim of the food jar.
- Tighten the lid firmly but do not overtighten, as this can damage the seal.
Food Not Staying Hot/Cold
- Verify that the lid is securely tightened to prevent heat transfer.
- Ensure the food jar was pre-heated or pre-cooled before adding contents.
- The effectiveness of insulation can be reduced if the jar is not filled sufficiently.
- Avoid opening the lid frequently, as this releases temperature.
Difficulty Opening Lid
- A vacuum can sometimes form, making the lid difficult to open. Try running the lid under warm water for a few seconds to expand the metal slightly.
- Ensure hands are dry for a better grip.
