This invention is concerned with an internal lid or seal for a liquid container, preferably paint in paint cans, that reduces the tendency of the liquid to separate, dry out, form a surface scum, or deteriorate. The internal lid serves as a removable internal barrier that floats on top of the paint and prevents contact with air that is left in partially filled containers for liquids. In addition to protecting the liquid, the internal seal also provides additional security against spills and leaks. This invention may be used with non-paint containers and non-paint products.
