Claim 0:
1. An auto-lock sealing valve structure of a rubber jointing ring having an auto-lock valve comprising:
a container;
a lid, the lid comprising:
an outside rim as a handle;
a lid body having a circular cylinder shape extending downwardly;
two vapor escaping grooves each disposed on opposing side surfaces of the lid body, the two vapor escaping grooves being provided symmetrically with respect to a center of the lid; and
a sole part having an outwardly extending edge, the sole part having an outer diameter larger than an outer diameter of the lid body; and

a rubber jointing ring comprising:
a body part which is a hollow cylinder;
four jointing ring layers disposed on an outside of the body part, a topmost jointing ring layer of the four jointing ring layers, immediate adjacent to an under side of the lid, having an upwardly expanding part, the topmost jointing ring layer being configured to be inserted in to a gap between the lid and an opening of the container; and
gaps disposed in a surface of each of the four jointing ring layers except the topmost jointing ring layer, the gaps being regularly and centrally symmetrically spaced around a circumference of each of the jointing ring layers except the topmost jointing ring layer,

wherein the four jointing ring layers each have a circular shape, an upper surface and a bottom surface,
wherein the container has a top part with an opening part and a cylindrical bottleneck, which is successively larger from a top of the container toward a bottom of the container.
