Today, plastic hot water bag
come in all shapes and sizes and are made from a variety of materials. Therefore, it is important to understand the pros and cons of each option and choose the right thermos for your specific needs.
The main aspects to consider are the size, material, shape and presence of the enclosure.
A large thermos (which we define as at least 1.5 liters in size) will be able to store more hot water and thus generate more heat than a smaller thermos. Because of the ratio between its surface area and water capacity, it can be expected to release heat over a longer period of time, all other things being equal. This will keep you warmer for longer.
Larger thermos are very effective when trying to heat or soothe body areas like the lower back because they can target a wider area at the same time. That said, once filled, they typically weigh twice as much as a small thermos, so people who aren't physically strong like the elderly need to be extra careful. A full 2 liter hot water with a lid usually weighs between 2 and 3 kg.
Smaller bottles are lighter, easier to fill and easier to carry, which means they deliver heat to specific and localized areas of your body more efficiently, especially when you need to lift and support it (for example, if you have a have a stiff neck). Due to these properties, they are also very suitable for children.
Small thermos or mini thermos are also easier to maintain and store. There is less risk of damage to the thermos because there is less material and less risk of burning and scolding. This is partly because they are lighter and take less time to fill.
Thermos are usually made of rubber, but can also be made from other sustainable products, such as thermoplastics. While generally more expensive, thermoplastic thermos are generally considered more eco-sustainable because they are made from recyclable and recyclable materials. Our Eco Thermos are made from 90% recycled materials. Rubber-free thermos, including thermoplastic products, have the added benefit of not giving off an odor like some rubber ones.
A notable example of a thermos with innovative shapes is the heart-shaped thermos. The other is a long hot water bottle. They work like a typical thermos, but are longer and narrower - more snake-like in shape and appearance.Hot water bottle warm belly hot compress hand warmer treasure water injection size warm water bag NZX-22
