The first hot water bottle is believed to have been made in the 16th century. It was initially a metal container filled with hot water and used to keep beds warm.
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.
Some common types of water bottles include stainless steel, glass, plastic, and insulated bottles. Stainless steel bottles are durable and keep drinks cold/hot for longer periods. Glass bottles are better for taste and do not retain odors. Plastic bottles are lightweight and economical, while insulated bottles maintain the temperature of liquids for extended periods.

That's the only way to sterilise baby bottles! Just make sure that the water is not too hot cause some bottles may melt.
