1. Core Concept

A universal, detachable cup handle that requires no glue and no modifications to the cup body. Originally designed to enhance grip comfort and outdoor portability for popular thermos flasks made of metal—such as RTIC and YETI—this innovative solution boasts key features like rapid attachment and detachment, easy cleaning, and integrated functionality.

2. Design Highlights

Plug‑and‑play compatibility: Leveraging an elastic snap‑fit mechanism, the handle securely clicks into place along the recessed groove at the base of the cup without causing any damage to the cup’s surface.

Ergonomic grip: The curved handle design delivers a comfortable, secure hold—perfect for users with larger hands or those who need a firm, stable grip during outdoor activities or while on the go.

Integrated hook hole: A standard mounting hole is incorporated at the handle’s end, allowing users to easily attach carabiners, hooks, or lanyards, making it simple to hang the cup from backpacks, belts, or table edges—and significantly boosting convenience for both outdoor adventures and daily commutes.

Simple and low‑maintenance: With no complex components, the handle can be disassembled and rinsed directly under running water for quick and hassle‑free cleaning.
