Vacuum flask Nuvita 4455 0.5 L — stainless steel, Rose

Nuvita 4455 is a 0.5 L vacuum flask designed to keep liquids hot or cold during daily use and travel. The bottle features a double-walled 18/8 stainless steel body with vacuum insulation that preserves temperature, and a Rose finish for a clean appearance. The flask is free from Bisphenol A (BPA), lead and phthalates, and its materials resist staining and odors so flavors and nutrients are preserved. An integrated LED thermometer in the lid allows quick, on-the-spot temperature checks, while an airtight screw lid prevents leaks and helps maintain the internal temperature. The wide 5.2 cm opening facilitates filling and thorough cleaning.

Advantages

The double-walled stainless steel construction and vacuum insulation provide long-lasting thermal performance, keeping liquids hot up to 12 hours and cold up to 24 hours. The integrated LED thermometer displays the internal temperature without opening the bottle, reducing heat loss and ensuring safe serving temperatures. The airtight lid minimizes spills and prolongs heat retention. Made from high-quality, BPA-, phthalate- and lead-free materials, the flask resists stains and odors and is suitable for repeated use. The compact 0.5 L capacity balances portability and practical volume for baby feeding, outings or travel.

Suitable for

• Keeping baby formula, milk or warm drinks at serving temperature during outings
• Storing cold water, juices or chilled beverages for day trips
• Travel, walks and outdoor activities where temperature retention and leak protection are needed
• Daily use at home, in a stroller or in a bag for quick temperature checks with the LED lid

How to use

Before first use and after each use, wash the flask and lid with warm soapy water and rinse thoroughly. To retain temperature, preheat or precool the bottle by rinsing it with hot or cold water respectively before filling. Close the lid securely to ensure the airtight seal and avoid spilling. Use the LED thermometer on the lid to verify liquid temperature before feeding or serving; consult the display to confirm a safe serving temperature. Clean the wide opening and interior with a soft brush to remove residues, and allow the bottle to dry with the lid removed.

Usage recommendations

Do not use the flask in a microwave. Avoid strong chemicals or bleach when cleaning to preserve the stainless steel finish and the sealing elements. Regularly check the lid gasket for wear and replace parts if necessary to maintain leak protection. For best thermal performance, fill the flask close to capacity and minimize the number of times the lid is opened during use.
