[New Product] Opens in 1 Second! The Evolved "One-Push Ice Pack Bottle" Launches in Late May

Yuryo Kokusai Co., Ltd. (Headquarters: Fukuoka Prefecture) will begin sequential sales of the "One-Push Ice Pack Bottle" from its heat-countermeasure brand "FRESH SWITCH" starting in late May 2026. Developed in response to the increase in "extreme heat days" (40°C or higher), the bottle features a new structure that allows for one-push opening and secure sealing in as little as one second. This ensures instant cooling even when hands are slippery with sweat. The product was developed based on customer feedback regarding the difficulty of opening traditional screw-cap bottles in summer and concerns about water leakage. Key features include a one-push cap, a 3-in-1 design (ice pack, water bottle, and hot water bottle), up to 40 hours of cooling power, a lightweight 285g slim design, and a soft silicone texture. It comes in 11 colors and is priced at an open price.
