Tiger Launches One-Push Vacuum Insulated Bottles MKR-V & MTR-V Series

Tiger Corporation (CEO: Yoshisato Kikuchi, Headquarters: Kadoma City, Osaka), a global leader in thermal control technology, will launch the “Vacuum Insulated Bottles MKR-V035/V050/V060” and “Vacuum Insulated Bottles MTR-V075/V088” on Tuesday, September 1, 2026.

In 2024, we introduced the MKR-W series, our first one-push model featuring the “Rakuraku Cap”—an innovative lid with an integrated gasket. Since its release, it has received overwhelming praise from our customers, with feedback such as, “With fewer parts and a dishwasher-safe design, cleaning is a breeze,” “The minimalist design ensures long-lasting use,” and “Its lightweight body makes carrying it stress-free.”

Building on this success, the new models (MKR-V and MTR-V series) also feature the “Rakuraku Cap” with its integrated gasket and are fully dishwasher-safe for effortless maintenance. Furtherplus, leveraging Tiger’s proprietary “spinning technique,” these bottles achieve a magically ultra-lightweight feel.

We have also meticulously pursued drinking comfort, paying close attention to fine details like the shape and height of the spout. The MKR-V series has even been awarded the “Human Life Ergonomics Certification” by the Human Life Ergonomics Research Center.
