Features and Functions

Thermos flask food jars are designed to keep food hot or cold for extended periods. They achieve this through a combination of features that work together to minimize heat transfer.

The key features of a thermos flask food jar include:

  • Vacuum insulation:The space between the inner and outer walls of the jar is evacuated, creating a vacuum that prevents heat transfer by conduction and convection.
  • Double-walled construction:The jar consists of two stainless steel walls with a vacuum between them. This provides additional insulation and prevents heat transfer by conduction.
  • Reflective coating:The inner surface of the outer wall is coated with a reflective material, such as aluminum, which reflects heat back into the jar.
  • Tight-fitting lid:The lid of the jar is designed to fit tightly, minimizing heat transfer by convection.

These features work together to create a highly efficient insulation system that keeps food hot or cold for hours.

Temperature Retention

The effectiveness of a thermos flask food jar in retaining temperature is measured by its temperature retention rating. This rating indicates how long the jar can keep food within a certain temperature range, typically 5°C to 60°C (41°F to 140°F).

The temperature retention rating of a thermos flask food jar depends on several factors, including:

  • Size:Larger jars have more insulation and can retain temperature for longer periods.
  • Shape:Jars with a narrow neck and a wide base retain temperature better than jars with a wide neck and a narrow base.
  • Materials:Jars made from high-quality materials, such as stainless steel, retain temperature better than jars made from lower-quality materials, such as plastic.
