Abstract

A bottle cap having a flow guide structure, comprising a base (1) and a cover (2) arranged on an upper end of the base (1). A blocking piece (3) is arranged on the base (1), an everted first bent edge (4) is arranged on an upper end of the blocking piece (3), and a sliding groove (5) is arranged between the base (1) and the blocking piece (3). A flow guide structure is arranged inside the sliding groove (5), the flow guide structure comprising a strip-shaped flow guide part (6). The slidable flow guide structure allows the flow guide structure to slide out of the sliding groove (5) when a user pours a liquid, causing the position at which the liquid flows out to become further away, preventing the liquid from flowing to the finish of a bottle or flowing down along the neck of the bottle. Meanwhile, the arrangement of the blocking piece (3) and the first bent edge (4) causes the liquid to be blocked by the blocking piece (3) before flowing to the flow guide structure when poured, and to be only able to flow along the blocking piece (3) to the flow guide structure, preventing the liquid flowing under the flow guide structure to the sliding groove (5). The present apparatus features a simple structure and convenient use, and provides the user with hygiene and safety assurance.
