Insulated Water Bottle THERMOS FUNTAINER 0.47 L, double-wall stainless steel, foldable carry handle

THERMOS FUNTAINER insulated water bottle, 0.47 L, is made from double-wall stainless steel to provide thermal retention and durable everyday use. The bottle features a foldable carry handle integrated into the lid, a leak-resistant closure and a corrosion-resistant interior and exterior suitable for repeated use. Its compact 0.47-litre capacity and robust construction make it convenient for school, commuting and outdoor activities where reliable temperature control and portability are required.

Advantages

The double-wall stainless steel construction reduces heat transfer to maintain beverage temperature longer than single-wall bottles, while offering improved impact resistance and corrosion resistance for long-term use. A foldable carry handle allows easier transport and attachment to bags without adding bulk. The leak-resistant lid design helps prevent spills in bags and backpacks and the compact size balances capacity with portability.

Suitable for

• Everyday hydration at school or the office
• Commuting and travel
• Walking, light hiking and outdoor recreation
• Children’s drinks for daycare or extracurricular activities

When it may not be suitable

This 0.47 L bottle may be insufficient for users who require large-volume hydration between refills, such as long-distance hikers or people doing extended outdoor work. It is not designed as a vacuum flask for multi-day temperature retention under extreme conditions; performance decreases over extended periods compared with larger insulated flasks designed for long-term thermal retention.

Key specifications

• Capacity: 0.47 litres
• Material: double-wall stainless steel (interior and exterior)
• Closure: leak-resistant lid with integrated foldable carry handle
• Finish: corrosion-resistant stainless surface
• Intended use: reusable insulated water bottle for beverages

How to use

Open the lid by releasing the closure and fill the bottle with your desired beverage, leaving a small air gap to avoid pressure buildup with hot liquids. Secure the lid firmly to maintain the leak-resistant seal and use the foldable carry handle for transport. For hot liquids, allow the beverage to cool slightly before closing to reduce internal pressure. Clean the bottle according to care instructions after each use to preserve the corrosion-resistant surfaces and sealing performance.

What to consider before purchase

• Required capacity versus portability — 0.47 L may suit daily use but is smaller than full-size flasks
• Whether a stainless-steel insulated bottle meets your thermal retention needs for the intended duration
• Compatibility with cup holders and backpack pockets due to bottle dimensions
• Cleaning access to the lid and mouth for hygiene maintenance

Usage recommendations

Use the THERMOS FUNTAINER for routine hydration: fill with cold or warm drinks for day trips, secure the leak-resistant lid before packing in a bag, and fold the carry handle when attaching to straps. Hand wash the lid and bottle components as recommended to maintain seal integrity and stainless surfaces.
