Cap having straw and reservoir for additive

Abstract

Disclosed is a cap having a straw and a reservoir for an additive. The cap includes: a fixture member having a straw attached to the reservoir, a container cap placed over the fixture member, and an opening member placed over the fixture member. The opening member has a cutter extending downward therefrom. The container cap has an upper cap coupler formed with a through-hole at an upper end thereof to allow passage of the straw and the cutter therethrough. The cutter is formed to communicate with the reservoir and open the bottom of the reservoir with a predetermined rotation of the opening member. The opening member further has a straw through-hole shaped to allow the straw to extend therethrough and remain upright during the predetermined rotation of the opening member.
