Flasker og emballasjetuber av plast

Portugal

I am looking to develop a shaker that can retain both hot and cold temperatures, providing the convenience of easily heating and cooling beverages with the press of a button. Additionally, this shaker will have a built-in mechanism designed to grind and mix food ingredients. Another product I am interested in creating is a cooler that can retain both hot and cold temperatures through an integrated mechanism within the cooler itself.
