Users can select to dispense only the liquid from the inner tube, only the liquid from the outer tube, or a mixture of both liquids by rotating the flip-top, achieving a three-stage dispensing function and meeting diverse usage needs.

[0014] 2. This utility model utilizes the aforementioned dual-color, three-stage dispensing flip-top bottle. Compared to existing technologies, due to its structure, the dual-color dispensing flip-top employs a combination design of a flip-top cap and a dispensing flip-top seat. Through the mutual cooperation of structures such as the first cap seat boss, the second cap seat boss, the first flip-top ring boss, the second flip-top ring boss, and the flange, it ensures that the flip-top effectively seals the first and second dispensing ports when closed, preventing liquid leakage and contamination. The flow guide valve and the dispensing flip-top seat are secured by structures such as ring bosses, ribs, and snap-fit ​​notches, ensuring reliable connection and easy assembly.

[0015] 3. This utility model utilizes the aforementioned dual-color, three-position dispensing flip-top bottle. Compared to existing technologies, this structure, with its three-position rotation indicator on the first cap protrusion of the dispensing flip-top seat and an easy-open opening on the front side wall of the flip-top, allows users to easily identify the current dispensing mode and conveniently open the flip-top for operation, thus improving the user experience. The limiting protrusion on the outer hose cooperates with the limiting part on the dispensing flip-top seat, limiting the relative rotation range, preventing excessive rotation, and providing a clear operational feel.

[0016] 4. This utility model utilizes the aforementioned dual-color, three-stage dispensing flip-top bottle. Compared to existing technologies, due to its structure, the inner and outer hoses are reliably connected and positioned by a first mating protrusion on the inner dispensing neck engaging with a third mating protrusion in the dispensing basin groove of the outer dispensing neck. The outer hose is fixed to the dual-color dispensing flip-top by a second mating protrusion on the outer dispensing neck engaging with an annular groove on the inner wall of the dispensing flip-top seat. The flow guide valve is also installed using a snap-fit ​​method. These snap-fit ​​structures ensure a stable connection between components, simplify the overall assembly process, and improve production efficiency.

[0017] 5. Compared with the prior art, this utility model utilizes a dual-color, three-stage dispensing flip-top bottle. Due to this structure, the main components of the bottle body and dispensing assembly can be made of common plastic materials such as PP polypropylene, resulting in lower cost, better chemical stability, easier processing and molding, suitability for large-scale production, and good market application prospects.
