Uphold is a folding reusable cup designed for contemporary lifestyles where the call for reduction in disposable plastics gives rise to portable beverage containers. The cup can carry drinks from freezing to boiling temperatures without discomfort to hold. It is collapsed to pocket-size for portability ideal for bag-free casual go-greeners! The cup’s geometry is mathematical and free from decorative concerns. Every edge and angle is designed to allow the user to convert it between the ‘collapsed’ and ‘extended’ states with ease. It redefines what a portable beverage container can be and is not only stylish and functional but also sustainable. - The cup materials have passed SGS tests to achieve food grade standard and are all BPA free. - The cup can carry beverages of up to 100°C in temperature. - The cup’s unique geometry reduces surface contact with the user’s hand to reduce discomfort caused by hot beverage, hence a sleeve is not needed for regular use. - The cup uses polymer Polypropylene (PP) as its body material which is relative stiff and can prevent spillage of beverage due to deformation. - The cup interior is smooth and seamless for ease of cleaning.
