AI Technical Summary
Technical Problem
Ink can drip from the cap of a liquid container when it is removed, causing stains on surfaces due to ink adhering to the cap's outlet and inlet pipes during the refilling process.
Method used
A liquid-containing bottle design with a nozzle, annular wall, and cap configuration that minimizes ink adherence to the cap by guiding liquid into a groove and using a sealing mechanism, along with a key member for identification and easy attachment, and ribs to prevent accumulation.
Benefits of technology
Reduces the likelihood of ink dripping from the cap after removal, ensuring cleaner refilling processes and easy identification of liquid types.

Abstract
To prevent that it is difficult for liquid to drip from a removed bottle cap 9.SOLUTION: In a bottle cap 9, an annular projecting piece 94 in an attached state abuts on a seat surface 865A, and the annular projecting piece 94 slides on a seat surface 865A in a circumferential direction θ1 in a process of removing the bottle cap 9. Further, since an annular groove 865E and inclined grooves 865F to 865H are formed on the seat surface 865A, ink adhering to the annular projection piece 94 is guided to the inclined grooves 865F to 865H. This ink flows down through the inclined grooves 865F to 865H into canal sections 866 to 868 due to adhesion force and gravity of the inclined grooves 865F to 865H.SELECTED DRAWING: Figure 10
