Insulation function. In this elegantly designed food container, you can easily transport your meals: from soup to solid foods to ice cream, everything is possible and can be implemented with ease. The screw cap guarantees absolute tightness, and the container is equipped to be shock and break-resistant. The mouth-blown glass vessel is made from double-walled insulating white glass. This allows for optimal and long-lasting insulation through vacuum and a special silver coating between the two glass layers. The plastic insert also protects the glass from impacts on the inside. Thus, a filled container achieves a heat retention time of approximately 24 hours and a cold retention time of up to 36 hours. High-quality sealing rings and the reliable screw cap ensure long-lasting and dependable use.
