Abstract: Beverage bottling plant with a beverage bottle closing machine for applying a screw-top bottle closure to a beverage bottle. The ring portion of the screw-top bottle closure has engaging surfaces which engage with engaging surfaces of the bottle to essentially prevent or minimize the rotation of the ring portion upon unscrewing of the screw-top bottle closure.

Abstract: A novel snap on pull off tamper indicating cap and neck configuration for containers, the cap having a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall. A removable tear skirt with continuous opposing groups of ratchet teeth on its inner surface depends from the outer peripheral edge of an out-turned flange on said annular wall. An inturned continuous annular rib on said annular depending wall engages on and deforms the neck configuration. The tear skirt is joined to the flange with multiple frangible connections from the ratchet teeth, a pull tab on the tear skirt with frangible lines requiring removal of the tab and tear skirt from the cap before the cap can be rotated.
