Vacuum Flask Ponza K31401 1.9 L Black Plastic
The Tefal Ponza K31401 vacuum flask is a 1.9 L black plastic thermos designed to maintain beverage temperature for extended periods. Constructed with durable materials and a streamlined exterior, this flask is intended for everyday use as well as outdoor activities. The double-wall insulation provides thermal retention that keeps drinks hot for up to 12 hours and cold for up to 24 hours, while the 1.9 L capacity accommodates large servings for family use or shared outings.
The vacuum flask combines lightweight plastic construction with reliable thermal performance. Its 1.9 L volume reduces the need for frequent refills, and the black finish offers a neutral, inconspicuous appearance. The thermal insulation specifications — up to 12 hours hot and 24 hours cold — make it suitable for both hot beverages and chilled drinks. The design emphasizes practicality and ease of handling.
Preheat or precool the flask by rinsing it with hot or cold water before adding the beverage to improve temperature retention. Open the stopper or lid, pour in the liquid without overfilling beyond the maximum fill line, and close the cap securely to preserve insulation. For pouring, follow the cap mechanism: unscrew or release the stopper as designed, pour the desired amount, and reseal the flask to maintain temperature.
For best results, fill the flask with liquid at the desired service temperature and minimize the number of times the flask is opened. Clean by hand with warm soapy water and avoid abrasive cleaners to preserve the exterior finish. Do not place the flask in a microwave or on direct heat sources. Use according to intended beverage types and avoid carbonated liquids to prevent pressure buildup.
