The present invention is directed to a lug cap or closure that is used in combination with a container for indicating that the container has been opened so as to indicate loss of seal or tampering. The lug cap includes an upper cap portion and a depending tamper or pilfer band, each having a series of circumferentially spaced lugs. The upper cap portion and the pilfer band are joined by a plurality of frangible bridges. The container finish includes combination camming/locking projections for locking the lugs into a locked position and for separating the pilfer band from the upper cap portion by a camming action when the container is opened. The lug cap may also include a secondary tamper indicating means such as a tamper indicating button in the top of the lug cap.

1. A package arrangement, comprising: a closure including an upper closure cap having a top wall portion and a depending skirt portion, and an annular pilfer band depending from and detachably connected to said skirt portion of said closure cap; and a container having an open mouth defined by a neck portion thereof to which said closure can be applied for closing said mouth, said closure including a plurality of upper lugs extending inwardly of said skirt portion for engagement with said container neck portion, and a plurality of lower lugs extending inwardly of said pilfer band for engagement with said container neck portion, said container neck portion including at least one camming/locking projection on the exterior thereof, said at least one camming/locking projection defining a pair of locking surfaces for respectively receiving a first pair of lugs, including one of said upper lugs and one of said lower lugs, when said closure is applied to said container, said at least one camming/locking projection further including at least one camming surface engageable with one of said lower lugs during removal of said closure from said container for separating said pilfer band from said closure cap. 2. A package arrangement in accordance with claim 1, wherein said at least one camming/locking projection includes a pair of diverging camming surfaces for respectively engaging a second pair of lugs, including another one of said upper lugs and another one of said lower lugs, during removal of said closure from said container. 3. A package arrangement in accordance with claim 2, wherein said locking surfaces of said at least one camming/locking projection are arranged in a relatively vertically and circumferentially spaced, stepped configuration, said upper and lower lugs of each said pair being positioned in circumferentially spaced relationship to correspond to the stepped configuration of said locking surfaces. 4. A package arrangement in accordance with claim 1, wherein said closure includes a sealing liner positioned adjacent the top wall portion of said closure cap. 5. A tamper-indicating closure for a container, comprising: a metallic upper closure cap having a top wall portion, and an annular skirt portion depending therefrom, said closure cap including a plurality of circumferentially spaced lugs extending integrally inwardly from said skirt portion for engagement with said container; and a metallic tamper-indicating pilfer band formed integrally with said closure cap and detachably joined thereto by a plurality of frangible bridges joining said pilfer band to said skirt portion, said closure including a plurality of upper lugs and a plurality of lower lugs respectively extending inwardly of said skirt portion and said pilfer band, said upper and lower lugs being arranged in circumferentially spaced pairs, where the lower lug of each pair is vertically and circumferentially spaced from the respective upper lug by a predetermined dimension, said pairs of lugs being configured for cooperation with said container for securing said closure in position thereon, and for separating said pilfer band from said skirt portion during removal of said closure from said container. 6. A tamper-indicating closure in accordance with claim 5, wherein each of said upper and lower lugs comprises an inwardly deformed portion of the respective metallic closure cap and metallic pilfer band.
