Bottle cap

Abstract

The invention relates to a bottle cap having a main body to which an operation part for opening a discharge member is assembled, and the operation part is arranged to discharge mixed content from a bottle through a discharge hole formed at the upper surface thereof when the discharge hole is opened. The discharge hole of the operating part is sealed by a sealing part assembled onto the discharge hole.
