    Abstract: A seal and saver container is composed of a bottle and a cover. The bottle has an opening bored at its top and a blocking ring positioned around its inner wall. The cover placed on the top of the bottle is provided with a first upper cover, a second upper cover, a compression spring, a sleeve, an anti-leaking ring and a grip. In using, place the cover on the bottle and move the grip to keep it tilted aside, so that the sleeve is dragged to move up and simultaneously the anti-leaking ring is also moved up to keep its bottom squeezed to project outward so as to lock with the blocking ring of the bottle. So, the opening of the bottle is totally sealed up to prevent the liquid in the bottle from leaking out.
