Although abdominal pain has very different meanings when used as an idiom, we will not talk about those who have a stomachache from plastics. On the contrary, as always, we would like to tell you about the place and simple solutions of plastics in our lives.
Abdominal pains caused by colds, gas and some diseases have been our nightmares. Immediately after the doctor's control, cold or hot compresses are recommended according to our situation, except for drug treatment. When it comes to hot compresses, hot water bags are growing, which provide great convenience to our lives.
Utensils for warmth in the bed began to be used in the 16th century. The earliest versions included hot coals from the dying embers of the fire, and these bed heaters were used to warm the bed before going into bed. Pots with hot water were also used in a short time, with the advantage of being able to stay in bed with the sleeper and not being hot enough to pose a fire risk. Prior to the invention of rubber that could withstand sufficient heat, these early hot water bottles were made of various materials such as zinc, copper, brass, glass, earthenware. Metal hot water flasks are wrapped in a soft cloth bag to prevent burning.
"Indian rubber" hot water bottles were in use in Britain in 1875. Modern traditional hot water bottles were patented in 1903 and are made from natural rubber or PVC according to a design patented by Croatian inventor Eduard Penkala. They are now usually covered with fabric, sometimes with a novelty design. Japanese-style plastic hot water bottle, locally known as Yutanpo, with cloth protective bag on the right. In the late 20th century, the use of hot water bottles declined significantly in most parts of the world. Not only were homes better heated, but newer products such as electric blankets were competing with hot water bottles as a source of nighttime heat.
However, the hot water bottle remains a popular alternative in Australia, Ireland, the UK, developing countries and rural areas. For example, the term "guatero" is widely used in Chile. It has grown in popularity lately in Japan, where it's seen as an eco-friendly and frugal way to keep warm. Some new products work like old bottles, but use polymer gel or wax on the heating pad. The pads can be heated in a microwave oven and are marketed as being safer than liquid-filled bottles or electrically heated appliances. Instead of the traditional square shape, the YuYu Bottle is designed to be long and flexible so it can be worn hands-free around the body thanks to the integrated tightening strap. Pain in the abdomen is relieved by using a hot water bag.
Our aim is not to say that those with stomachache should use a hot water bag… Our aim is to explain how plastics take their place in our lives and to explain their place in our lives very well.
