ABSTRACT:
Provided is tamper-indicating plastic bottle cap to be fitted to a bottle neck having a bead, which cap is comprised of (a) an inner stopper member having a skirt provided with an annular projection for engaging over the bottle bead and (b) an outer cap member having a skirt. Either the skirt of the inner stopper member or the skirt of the outer cap member has first and second annular recesses and the other has an annular projection to be received in the first and second recesses. The skirt of the inner stopper member is broader toward the lower terminal edge thereof so that the broadened portion forms a stopping shoulder on which the lower end of the skirt of the outer cap member is caught therein so as to avoid the risk of the outer cap member being inadvertently brought into a seal position relative to the inner stopper member during shipping and storage of the bottle cap.
