Tamper-evident closure

A closure for a container, the closure comprising:

• A cylindrical base configured to attach to a mouth of the container;
• a spout disposed within the cylindrical base, a void space being defined between the spout and the cylindrical base, the spout being configured to be disposed upon, and in fluid communication with, the mouth of the container;
• a cap comprising a top cover, an inner body member extending from a surface of the top cover, and an outer body member extending from an edge of the top cover about the inner body member, the inner body member enclosing the spout and forming a seal therewith when the cap is disposed upon the cylindrical base;
• and
• at least one tamper-evident device extending between and locking together the cap and the cylindrical base;
• the at least one tamper-evident device comprises a flattened member extending from the inner body member at an edge of the inner body member opposite the top cover, the at least one tamper-evident device being unified with the inner body member by at least one frangible link configured to rupture when the cap is removed from the cylindrical base, the at least one tamper-evident device being subsequently retained in the void space and at least partially obscured by the cylindrical base.
