Structural Design

1. One-piece molded sloped cup body: The internal cavity is precisely matched to the outer diameter of a standard 7-oz disposable paper cup, with a slanted opening that allows the cup to snap in directly and stay securely in place without slipping.

2. Integrated widened side handle: The grip surface features an anti-slip texture, making it easy to hold with one hand while preventing slippage.

3. Thickened, layered cup wall design creates a hollow insulating layer that effectively blocks heat transfer from the hot liquid inside the paper cup.

4. Seamless, all-in-one construction achieved through 3D printing; the flat bottom ensures stable upright placement, accommodating both tabletop use and handheld operation.

Applicable Uses

1. Heat Insulation and Scald Prevention: When serving hot water, tea, or coffee, the insulated cup wall keeps your hands safely away from the scorching surface, solving the common problem of burning hands with thin paper cups.

2. Convenient Handheld Use: With its built-in handle, this lightweight cup eliminates the need for additional gripping points—simply slip it on and carry it steadily, making pouring and sipping much more secure even while on the move.

3. Reusable and Eco-Friendly: Made from rigid PLA/PETG materials that are both waterproof and temperature‑resistant, it can be repeatedly used with disposable paper cups, reducing waste from paper cup sleeves and promoting sustainability.

4. Versatile Adaptability: Suitable for a wide range of settings—including offices, tea rooms, retail outlets, home drinking, and temporary events—this product fits standard‑size disposable paper cups, allowing you to quickly slip it over any cup for convenient, on‑demand use.
