The service life of a thermos depends on the quality and usage of the cup, but if used correctly and cleaned regularly, it can generally be used for 3-5 years.
1. Service life of insulated cups
The service life of a thermos depends on multiple factors, with the two most important being the quality and usage of the cup. Specifically, if the cup material is good, it is not unlucky or bumped during use, and it is regularly cleaned and kept dry, then the lifespan of the thermos cup will be longer.
Insulated cups with high-quality stainless steel or glass inner liners have a relatively long lifespan, up to 3-5 years. However, if low-quality insulation cups are used, or if they are used improperly, such as inverted or collided with hard objects, their lifespan will be significantly shortened.
2. Proper use of insulated cups
In order to extend the service life of the insulated cup, we need to use it correctly.
Firstly, when using a thermos correctly, the following points should be noted:
(1) Choose products with reliable quality when making a purchase;
(2) Use a thermos when the temperature is appropriate to avoid filling drinks that are too hot or too cold;
(3) After pouring hot or cold drinks, promptly close the cup lid to avoid temperature loss;
(4) Pay attention to the expiration date of the thermos cup and do not continue to use it after it has expired.
Secondly, maintaining the thermos cup is also very important. Properly cleaning the thermos can not only remove odors, but also sterilize, remove dirt, and extend its service life. The specific method is as follows:
(1) Rinse the thermos promptly after each use and wipe the body with a dry towel;
(2) Regularly use a specialized cleaning agent for thermos cups, spray it inside the cup, and rinse thoroughly after leaving it for a period of time;
(3) Avoid storing insulated cups that are not cleaned for a long time, especially those that have been used to hold drinks such as milk and juice that are prone to bacterial growth;
(4) Using natural cleaning agents such as baking soda, white vinegar, or lemon juice for cleaning is also a good choice.
In short, the service life and lifespan of insulated cups depend on various factors. We need to choose, use, and maintain insulated cups correctly in order to ensure their effectiveness and lifespan.
