AI Technical Summary
Technical Problem
Existing bottle caps can only hold a single liquid, necessitating multiple bottles for different liquids, and existing dual-liquid bottles cannot separate or use liquids individually after mixing.
Method used
A double-pipe extrusion bottle cap with an outer and inner pipe, each with separate outlet holes and outlets, allowing simultaneous or separate discharge modes through a rotatable lower cap and flipping upper cap, featuring convex and concave parts for mode switching and elastic members for secure sealing and feedback.
Benefits of technology
Enables simultaneous or separate discharge of liquids, ensuring secure sealing and easy mode switching with tactile and auditory feedback, reducing the need for multiple bottles and accommodating varying usage scenarios.

Abstract
The present application discloses a double-pipe extrusion bottle cap, and relates to the technical field related to bottle caps, comprising a hose and a bottle cap arranged on an open end of the hose. The hose comprises an outer pipe and an inner pipe, and the outer pipe is provided with a first liquid outlet hole for liquid in the inner pipe to be discharged and a second liquid outlet hole for liquid in the outer pipe to be discharged; the bottle cap comprises a lower cap rotatably connected to the hose, the lower cap is provided with an upper cap in a flipping manner, and the lower cap is provided with a first liquid outlet and a second liquid outlet; and the following three liquid discharge modes can be achieved during a rotation stroke of the bottle cap: mode 1: when the first liquid outlet is communicated with the second liquid outlet hole, and the second liquid outlet is communicated with the first liquid outlet hole, the liquid in the inner pipe and the liquid in the outer pipe can be discharged simultaneously; mode 2: when the first liquid outlet hole is communicated with the first liquid outlet, the liquid in the inner pipe can be discharged; mode 3: when the second liquid outlet hole is communicated with the second liquid outlet, the liquid in the outer pipe can be discharged.
