Introduction
This instruction manual provides important information for the proper use and care of your THERMOS Stainless King 16-ounce Vacuum-Insulated Food Jar. This food jar is designed to maintain the temperature of your food, keeping hot items hot for up to 9 hours and cold items cold for up to 14 hours. Constructed from high-quality 18/8 stainless steel, it is durable and suitable for various uses, from daily lunches to outdoor activities. The design includes a full-sized folding spoon stored conveniently within the lid, which also doubles as a serving bowl. The exterior remains cool to the touch with hot contents and sweat-proof with cold contents. For best results and longevity, please follow the instructions outlined below.
Setup
Initial Cleaning
Before first use, and after each use, thoroughly clean all parts of the food jar. Disassemble the lid components, including the main lid, the inner stopper, and the folding spoon. Wash all parts with warm water and mild dish soap. Rinse thoroughly. Allow all parts to air dry completely before reassembling or storing.
Pre-conditioning for Optimal Performance
To maximize thermal efficiency, pre-condition your food jar:
- For Hot Contents: Fill the food jar with hot tap water. Attach the lid and let it stand for 5 to 10 minutes. Empty the water before filling with hot food.
- For Cold Contents: Fill the food jar with cold tap water. Attach the lid and let it stand for 5 to 10 minutes. Empty the water before filling with cold food.

Operating Instructions
Filling the Food Jar
After pre-conditioning, fill the food jar with your desired hot or cold food. Do not overfill. Ensure there is enough space to securely attach the inner stopper and outer lid.
Securing the Lid
Place the inner stopper onto the food jar and twist clockwise until it is firmly sealed. Then, place the outer lid (which doubles as a serving bowl) over the inner stopper and twist clockwise until it is tight. Ensure both lids are securely fastened to prevent leaks and maintain temperature.
Using the Folding Spoon
The food jar includes a full-sized stainless steel spoon that folds for compact storage. To access, unscrew the outer lid and locate the spoon stored within the inner stopper. Unfold the spoon for use. After use, clean the spoon, fold it, and return it to its storage slot.

Maintenance and Cleaning
Dishwasher Safe
The THERMOS Stainless King food jar and its components are dishwasher safe. For best results, place all parts on the top rack of your dishwasher.
Hand Washing
For thorough cleaning, especially of the lid components, hand washing is recommended. Disassemble the lid by unscrewing the inner stopper. The silicone seal around the inner lid can be carefully removed for separate cleaning to prevent mold growth. Wash all parts with warm, soapy water, rinse thoroughly, and allow to air dry completely before reassembly.

Troubleshooting
- Food not staying hot/cold: Ensure the food jar was properly pre-conditioned (pre-heated or pre-chilled) before adding food. Verify that both the inner stopper and outer lid are securely tightened to create an airtight seal.
- Lid is difficult to open: If hot food was placed in the jar, a vacuum may form as it cools, making the lid difficult to open. Avoid over-tightening the lid when the contents are hot. If stuck, try running warm water over the lid for a few seconds to help release the seal.
- Leakage: Check that all seals (including the silicone gasket on the inner stopper) are properly seated and free from food debris. Ensure both the inner stopper and outer lid are fully tightened.
