Production Technology

The 316L stainless steel interior has a chromium oxide passivation layer that offers excellent corrosion resistance and reduces heavy metal leaching. The copper plated inner walls reflect thermal radiation efficiently, working with a vacuum insulation layer for superior temperature retention. The PP plastic lid incorporates an antibacterial color masterbatch, inhibiting over 90 percent of bacterial growth. The PCT main body withstands heat and impact, making it microwave safe.

Design Challenge

Careful observation shows that handles on traditional baby tumblers are usually attached with clips or screws. With regular use, these fasteners often loosen or detach, posing a choking hazard and diminishing the overall experience.
This design solves the issue at its source. Rather than being an added component, the handle is fixed directly with the lid, becoming an inseparable part of the overall design. In this approach, utility becomes an essential expression of the form itself.

Project Duration

The design and development of this thermal tumbler started in Shanghai, in June 2024. It was introduced to the Chinese market in August 2025.

Operation Flow

The lid opens in two stages to gradually release internal pressure, preventing liquid spurts and reducing scalding risks. It also remains leakproof in any position. A safety lock operated with a single button stops little hands from opening it by accident. The discreet, ergonomic handle design is durable for everyday use and perfectly sized for small hands to hold easily. The straw offers optimal comfort, designed to support the natural sucking reflex of infants.

Research

Feeding times can be long for infants, and their delicate digestive systems are still maturing, making them sensitive to drinks that are too hot or too cold. To support gentle, healthy feeding, this tumbler combines advanced insulation technology and antibacterial materials. It keeps liquids at a comfortably safe temperature while helping to keep germs at bay, delivering peace of mind and hygienic sips with every use.

Inspiration

Inspired by the pure, gentle world as seen by infants, the design ditches loud colors and excessive decoration in favor of soft macaron hues to create a calm, warm visual feel. A cylindrical body is paired with a smooth, symmetrical curved handle. Their sleek, rounded lines radiate approachability and comfort. The discreet handle design blends seamlessly into the overall silhouette, enhancing the minimalist, clean aesthetic without compromising everyday functionality.
