Keep Drinks Cold Longer: New 'Bottle in Bottle' Holders Feature Square Bottle Compatibility and Triple-Screw Mechanism

Atlas Co., Ltd., a planner, manufacturer, and seller of stainless steel tabletop and kitchenware, will launch the 'Folding Type (E2)' on June 1, 2026, and the 'Strap Type (A2)' and 'Handle Type (C2)' on June 15, 2026, as part of its 'BOTTLE in BOTTLE' series. This series utilizes a vacuum-insulated double-wall structure to minimize external temperature influence, keeping drinks cold or hot for extended periods. The new models now support square-shaped PET bottles and feature a triple-screw structure for faster opening and closing compared to previous versions. The lineup includes a foldable type for easy storage, a strap type for versatile carrying, and a fixed-handle type with a wide grip. Since the surface does not develop condensation, it keeps bags and tables dry, making it ideal for both indoor and outdoor use.

The main body uses the same 'vacuum-insulated structure' as a thermos, ensuring that both cold and hot drinks stay at their ideal temperature for a long time. The series has surpassed 5 million units in cumulative shipments and is supported by many users. Because you don't need to pour drinks directly into the holder, it is easy to clean and maintain. Additionally, the design hides the bottle label, making it discreet for use in offices and other public settings.

By increasing the inner diameter to approximately 77mm, the holder now accommodates square PET bottles while maintaining its compact size. The lineup includes models for 600mL-700mL, 500mL-650mL, and a hot-drink mini size for 300mL-500mL. The new triple-screw mechanism allows for easier opening and closing with fewer rotations, achieving approximately 1.5 times smoother operation compared to conventional products.
