A hot water bag is very meaningful for our healthy life. In addition to keeping the body warm, it can also relieve anxiety to treat various discomforts in the body. How can I buy a high-quality, satisfying hot water bag?

    This article will help you understand how to distinguish good and bad hot water bottles.

    Observe the shape of the hot water bottle. When we choose a hot water bottle, we should pay attention to observe the shape of the hot water bottle to see if there is any defect in the shape of it, and whether the bonding between the water inlet of the hot water bottle and the rubber of the bag body is firm. If there is any problem, do not buy it. Smell the hot water bottle. Hot water bottles are mostly made of plastic and rubber, so they generally have a certain plastic smell. However, the plastic smell of the normal hot water bottle is relatively small. If the hot water bottle has a strong smell, it means that the material of the plastic bag is not very good. It is best not to buy this kind of hot water bottle. Check the tightness of the hot water bottle. The most important thing is to check the tightness of the hot water bag. We can first pour some hot water into the hot book bag, and then observe whether the hot water bag has water leakage or bubbling. If there is, it means that there is a problem with the hot water bag.

    Check whether the elasticity of the hot water bottle is good. The elasticity of the hot water bottle is good indicating that the rubber content of the hot water bottle is relatively high, and the filler is relatively small. When purchasing, you can use the hand to touch the hot water bottle. It is better for those with a thick feel. Then look at the hot water bottle for pollution. Because the hot water bottle is in contact with human skin, there should be no color migration on the surface. Simple identification method: wipe the hot water bottle with absorbent cotton to see if the absorbent cotton is contaminated by color. The lighter the pollution, the smaller the color migration. Then look at the firmness of the bonding between the filling port of the hot water bag and the rubber of the bag body. The joint can be turned over by hand, and there should be no cracks or degumming in the joint. Look at the color of the hot water bottle is bright. The brightly colored hot water bottle indicates that the raw materials used in the manufacture of the hot water bottle are relatively pure and the production process control is relatively strict. Finally, check whether the screw of the hot water bottle filling port has slippery teeth. If there are slippery teeth, the hot water bottle is easy to leak. When choosing, you should choose a hot water bottle with a smooth surface of the screw cap and clear threads.
