This article aims to provide a detailed guide on the initial handling and use of newly purchased insulated cups. The main points include washing, disinfection, water temperature testing, insulation effect testing, and correct use.
1. Washing and disinfection
After receiving the new thermos, the primary task is to wash and disinfect it. This ensures the hygiene inside the cup and removes factory residue.
(1) Wash the inside and outside of the thermos cup with warm water and neutral detergent for the first time. Avoid using irritating detergents or cleaning agents containing acidic components to prevent damage to the surface of the cup.
(2) Use a soft brush or sponge to clean the lid and concealed parts of the cup. Ensure that all parts are thoroughly cleaned.
(3) Carefully rinse the thermos to ensure that all detergent and residue are removed.
(4) Soak the thermos and lid in boiling water or food grade disinfectant for at least 15 minutes, then rinse carefully to ensure thorough disinfection.
2. Test water temperature
Before using a thermos, it is important to be familiar with its insulation performance and the appropriate range of water temperature.
(1) Fill the cup with at least 2/3 of its capacity to more accurately test the insulation effect of the thermos.
(2) Use a water heater or kettle to heat the water to the desired temperature.
(3) Pour into the thermos and cover the lid tightly. Wait for a certain amount of time (depending on the brand and model of the thermos, the waiting time may also vary).
(4) Open the cup lid and use a thermometer or hand to feel the water temperature inside the cup. Ensure that the temperature is within the required range.
3. Thermal insulation effect test
The insulation effect of the thermos cup is one of the main purposes for purchasing this product. The following are the steps to test the insulation effect:
(1) Fill the cup with hot water and close the lid tightly.
(2) According to the instructions of the cup, record the initial temperature.
(3) After waiting for a fixed time (e.g. 4 hours), measure the water temperature again.
(4) Compare the temperature changes between the initial temperature and the end temperature. If the insulation cup is effective, the temperature change should be minimal and within the acceptable range.
4. Correct usage method
The correct usage method helps to maintain the insulation effect and lifespan of the thermos cup.
(1) Follow the manufacturer’s guidelines for maximum capacity and optimal filling water level.
(2) Close the cup lid and ensure the seal is intact to prevent heat from escaping.
(3) Avoid leaving hot liquids or cold drinks in the cup for a long time to avoid affecting the insulation effect.
(4) Regularly clean the thermos to maintain its cleanliness and hygiene. Avoid using abrasive cleaners to prevent scratches on the surface of the cup.
By correctly washing and disinfecting newly purchased thermos cups, understanding the steps for testing water temperature and insulation effect, and mastering the correct usage methods, the hygiene and optimal performance of thermos cups can be ensured. Proper maintenance and use will extend the service life of the thermos and provide you with long-lasting hot beverage enjoyment.
