Abstract
Abstract A bottle closure in which the neck of the bottle is provided with upper and lower threaded portions separated by an unthreaded portion divided into two parts by an annular bead. A cap is provided with upper and lower internally threaded portions separated by an unthreaded portion of a width substantially equal to the width of the unthreaded portion of the neck. When removing the cap, the bead interferes with the lower threaded portion of the cap providing resistance to easy removal.
