Removable locking container cover
View Patent ↗A container cover for use with a container having a neck with a rim. The cover includes a lid with a spout hole, a skirt extending downward from the circumference of the lid, a concentric plug seal extending downward from the lid inside the skirt, a spout hole door hingeably connected to the lid, and at least one non-flexing lock and one flexing lock, each having an inwardly projecting wedge, which lock the cover in place on the container by engaging the bead ring.
