What is the old fashioned hot water bottle called?

Answered by Douglas Hiatt

The old fashioned hot water bottle is commonly referred to as a “rubber hot water bottle” or simply a “hot water bottle.” It was a popular household item used for providing warmth and comfort during colder months or for relieving various aches and pains.

The concept of a hot water bottle dates back centuries, but the rubber version that we are familiar with today became popular in the early 20th century. It was a significant improvement over the earlier models made from materials such as metal or glass, which were prone to breakage and not as flexible or comfortable to use.

One of the earliest known patents for a rubber hot water bottle was filed by Slavoljub Eduard Penkala, a naturalized Croatian engineer, in 1903. Penkala, who was born to a Polish father and Dutch mother, was a prolific inventor with numerous notable inventions to his name.

His invention, known as the “Termofor,” revolutionized the way hot water bottles were made and used. The Termofor was made from rubber, which made it more durable, flexible, and safer to handle than the previous alternatives. Its design included a screw-in stopper to prevent leakage and a ribbed surface to enhance heat retention.

Penkala’s rubber hot water bottle quickly gained popularity and became a household staple in many parts of the world. It provided a reliable and convenient source of warmth during cold nights, and its therapeutic benefits were widely recognized.

The term “Termofor” itself is derived from the combination of the words “termo” (meaning heat) and “for” (indicating its purpose). This name accurately described its function as a device for storing and delivering heat.

Over the years, the design and materials used for hot water bottles have evolved. Today, hot water bottles are typically made from durable, BPA-free rubber or thermoplastic materials. They come in various sizes, shapes, and colors, with features such as ribbed surfaces or soft covers for added comfort.

While newer alternatives like electric heating pads or microwavable heat packs have gained popularity, the traditional rubber hot water bottle still holds a special place in the hearts of many. Its simplicity, reliability, and comforting warmth make it a timeless and beloved household item.
