ABSTRACT:
A one piece molded push on tamper resistant closure suited for reusable bottles such as rnilk bottles comprises a cap portion and a latch ring portion connected thereto by frangible tabs. Rupture of the tabs serves to detach the cap portion to permit its removal from the bottle, while simultaneously opening the latch ring portion to permit it to be removed laterally from about the neck of the bottle. The closure may also include a pull tab disposed on the cap portion to provide a levered fore for rupturing the frangible tabs.
