Rang Dong Makes Flip-Top Thermal Tumbler for Daily Use
A good drink loses its appeal fast once it goes lukewarm or the ice melts. The RD-CGN045ST1.E thermal tumbler from Rang Dong, Vietnam's leading manufacturer of vacuum flask products, is built to retain a chosen temperature of a beverage for the whole day.
A mug or tumbler that loses its temperature within an hour rarely keeps up with a full day away from home, whether that means a commute, a workday or errands in the heat. Switching between cups for hot and cold drinks, or reheating coffee partway through the morning, adds friction to an otherwise simple routine.
Rang Dong’s thermal tumbler addresses this issue directly, holding a set temperature for hours regardless of what is inside.
Long temperature retention
The double-wall vacuum insulation chosen by Rang Dong for its thermal tumbler keeps drinks hot for up to 12 hours, or cold for up to 24 hours, so a coffee poured in the morning stays hot through most of a workday, and a cold drink filled before heading out stays cold well into the evening.
Besides, model RD-CGN045ST1.E has several advantages in its components and materials.
Its lid flips open with one hand, allowing direct sipping without having to remove the cap, a feature useful while driving, walking or at deskwork.
A wide opening allows large ice cubes to be added directly. The structure helps ease the cleaning of residue and odors trapped inside the appliance.
Food-grade stainless steel
The body is made from food-grade SUS 304 stainless steel, which resists rust, does not alter the taste or smell of drinks and holds up to repeated daily use without retaining odors from previous drinks.
The same steel grade is used across Rang Dong's lineup of flasks and tumblers, chosen for its balance of durability and food safety.
Portable, everyday design
A carry strap attaches to the lid for hand-carrying or clipping onto a bag, while the tumbler's shape is sized to fit standard car cup holders alongside a comfortable grip for everyday carrying.
The finish shown in the photo above is a soft pink, giving the tumbler a look suited to everyday carry rather than a purely utilitarian appearance.
Addition to flask lineup
Model RD-CGN045ST1.E is a recent addition to Rang Dong's vacuum flask range, built on the same insulation and stainless steel construction used across the company's other flasks and tumblers, with the flip-top lid and the wide mouth set as its distinguishing features within the lineup.
For consumers wishing a hot drink to stay hot or a cold drink to remain cold throughout the day, model RD-CGN045ST1.E offers a reliable, easy-to-clean option for daily use. Built with a number of advantages, the thermal tumbler fits naturally into a morning commute, an office desk or a day outing, and it holds up to the same routine day after day.
