package. 2. The peripheral bead of claim 1, wherein the peripheral bead includes a step portion, the step portion assisting in producing an audible sound during flipping of the first closure portion relative to the second closure portion. package. The package of claim 1, wherein the tab is configured to lock against the peripheral bead. The package of claim 1, wherein the depth of the peripheral bead is less than the depth of the external thread formation. 2. The package of claim 1, wherein the peripheral bead has a depth of about 0.2 mm to about 0.6 mm and the external thread formation has a depth of about 1.2 mm to about 2.0 mm. 2. The package of claim 1, wherein the ratio of the depth of the external thread formation to the depth of the peripheral bead is about 2 to about 8. 7. The package of claim 6 , wherein the ratio of the depth of the external thread formation to the depth of the peripheral bead is about 3 to about 5. The package of claim 1, wherein the area between the first frangible connection and the second frangible connection forms a hinge area that assists in moving and locking the tab. . 2. The package of claim 1, wherein the second frangible connection is entirely located further from the top wall than the first frangible connection. It is a package,
A container having a neck defining an opening, the container having an external thread formation on the neck and a peripheral bead, the peripheral bead being located further from the opening than the external thread formation. ,
a closure configured to be attached to the neck of the container to close the opening, the closure comprising a first closure section and a second closure section, the first closure section being made of a polymer; a top wall, a polymeric annular skirt, a first frangible connection, and a second frangible connection, the polymeric annular skirt extending downwardly from the polymeric top wall; The annular skirt portion includes an internal thread formation that engages the external thread formation of the container, and the second closure portion is a polymeric tamper-evident band extending downwardly from the polymeric annular skirt portion, and the second closure portion includes a polymeric tamper-evident band extending downwardly from the polymeric annular skirt portion; a closure comprising a polymeric tamper-evident band releasably connected to the polymeric annular skirt portion by a frangible connection;
including;
