Covered by a protective toweling, the hot-water bottle is placed on the treatment area and left until the water has cooled off.
A hot water bottle was primarily used to warm warm parts of your body, such as your head when you were ill. This practice was primarily used during the 16-17th centuries.
Hot water bottles are made from polyvinyl chloride(PVC) and rubber. Hot water bottles are manufactured such that they don't leak ,have long durability and provide good heat.
Hot water bottles work by filling them with hot water from a kettle or tap. The heat is then trapped inside the rubber or silicone bottle, providing warmth for several hours. The hot water bottle is placed against the body to provide therapeutic heat for comfort or pain relief.

Because this is the part of our kitchen
Because the melting point of the plastic used to make the bottle is lower than the temperature of the water that you have put in it. Plastic bottles are 'blow molded'. Basically air is forced inside a small piece of hot plastic and it expands like a balloon, except that this 'balloon' is inside a form or mold in the shape of the bottle. It is cooled and the bottle shape stays. If the softening point of the bottle is lower than the hot liquid poured in, then the plastic 'balloon' wants to shrink again.
