Bottle cap

Abstract

The present invention concerns a bottle cap containing heterogeneous materials including a main body attached to a container mouth and an activating upper cap that is assembled on an upper mouth of said main body. Rotation of said upper cap turns a prefabricated receptacle attached to the lower portion of said upper cap, opening a seal formed on the lower portion of said main body and concurrently allowing the heterogeneous materials contained inside said receptacle to drop inside the container. Said main body has a space formed at an outer part of the lower portion of said seal, and a cut line separator formed at the bottom of said receptacle is disposed within said space. Said receptacle is connected to the bottom of said upper cap. Rotation of said upper cap turns said receptacle so that said cut line separator formed at the bottom of said receptacle breaks a cut line that starts from said space, resulting in said cut line separator pushing said seal down and allowing the heterogeneous materials contained in said receptacle to drop and mix with the contents of the container.
