As the temperature gradually drops, PVC hot water bottles，with their lightweight and excellent insulation properties, have become a practical and useful item for many people to keep warm. However, to use it safely and effectively, it is crucial to master the correct usage and maintenance methods, which can not only extend the service life but also ensure the safety of use.

The water filling process is the foundation for safe use. It is recommended to use warm water at a temperature of 40-60℃. Avoid injecting boiling water as high temperature can cause the PVC material to age, deform, and even lead to leakage risks. Do not fill the bag too full. Reserve about one-third of the space. Before tightening the cap, release the residual air in the bag to reduce the expansion pressure during use. At the same time, check the sealing performance of the cap to ensure there is no loosening. 

When using it daily, it is important to consider the scene adaptation. The PVC hot water bottle can be used to keep the hands, waist and abdomen warm. It is especially suitable for people who sit at work for a long time to relieve the coolness in the back and waist. It can also provide gentle warmth for the elderly and children. However, it should not come into direct contact with the skin. A special fleece cover can be used to match it, which can not only reduce the cold stimulation but also prevent discomfort caused by the friction between the PVC material and the skin, and reduce the risk of burns. 

Proper maintenance can extend its service life. After use, empty the internal moisture, wipe it clean with a dry cloth, and let it dry naturally in a ventilated and dry place. Avoid direct sunlight or proximity to heat sources to prevent the material from hardening or cracking. When storing, avoid folding or squeezing. You can place it flat or put it in a velvet cover for storage. Keep it away from sharp objects to prevent surface damage. If you find scratches or bulges on the bag body, replace it immediately. Do not continue to use it.
