ABSTRACT:
A tortuous passage cover for flexible liquid container comprises an upper cover body having an outlet in the central area, and an upper joint ring and a lower joint ring integrally formed thereto; and a lower cover body having a cylindrical protrusion and a plurality of projecting rings and outlet openings formed thereto closely linked to the bottom portion of the upper cover body in defining a tortuous passage channel therein and communicating with the outlet of the upper cover body and the outlet openings of the lower cover body. Therefore, by means of the tortuous resistance offered by the tortuous passage channel, the liquor contained in the container furnished with this cover will not flow out when the container is accidently tipped over.
