Explanation:
Removal of air and incomplete filling of water bag is perhaps due to the same reason. The bag needs to be flexible and inelastic that is it should stay in a desired shape in a desired position for some time which won't be possible if the bag is full.
Answer:
It's crucial that neither the water nor the air in your hot water bottle are overinflated. Completely filling your hot water bottle prevents the water from flowing freely and puts pressure on the hot water bottle. When you are using it, if pressure is applied, it could "POP!" and cause catastrophic injury. Due of this, the British Standard Instructions recommend only filling the container to 2/3rds. Similarly, a hot water bottle could "POP" while in use if the air inside is not released.
Explanation:
1. Avoid using boiling water to fill your hot water bottle. Before filling your bottle after the water has boiled, let it sit for a few minutes. Boiling water splashback from filling a bottle runs the risk of causing burns.
2. Hold the bottle by the neck in an upright posture while you slowly fill it to prevent water splashback.
3. Never fill your bottle more than two thirds of the way full.
4. ALWAYS empty the bottle of air by carefully placing it on a level surface until water is visible at the opening.
5. Make sure the stopper is snug enough to prevent leaks. Finger tight ought to be sufficient.
6 Always fill hot water bottles by responsible adult
