Abstract: A threaded tumbler bottle cap includes a cap handle, a cap base, and a strainer. The cap base includes a flange, an annular wall, an opening, and a lateral wall. The lateral wall that threadedly attaches to a tumbler is perimetrically connected around the annular wall. The opening that allows the stored beverage to flow through concentrically traverses through the annular wall. The flange is concentrically positioned around the opening and externally connected onto the annular wall so that the stored beverage can be discharged from the tumbler. The strainer is internally engaged within the flange to keep the ice cubes within the tumbler. The cap handle is threadedly engaged around the lateral wall as the annular wall and the flange being enclosed by the cap handle. The flange is hermetically pressed against the cap handle thus preventing any leakage of stored beverage.
