It keeps liquids hot or cold for hours, and its design stays cool to the touch even with hot contents. The sweat-proof exterior helps prevent condensation in bags and car seats, while the 0.5-litre capacity is sized for a single feed or multiple mixes on longer trips.
Key features include a robust build for everyday use, high temperature retention, and user-friendly handling. This model is ideal for parents who need reliable temperature control for freshly prepared formula or pre-boiled water that may later be mixed with powder. The absence of temperature fluctuation helps ensure safe feeding times when access to a kitchen isn’t available.

The Miniland 500ml Thermo for Liquids is designed for outings and daily use, keeping drinks at the right temperature for over 24 hours.

A push-seal closure provides an easy, leak-proof pouring experience, reducing spill risks when feeding on the go.
Materials are chosen for safety and long life, with a focus on maintaining liquid stability across temperature variations. This makes it well suited for parents who travel, attend activities, or require a dependable bottle for car rides. The combination of high-quality steel and a practical closure system supports convenient, on-demand feeding without additional containers.
