EASY-OPENING CONTAINER CLOSURE HAVING A SLIDING TAB

摘要

A can end of the easy opening type includes an end panel having a dispensing aperture and a partially preformed vent hole. An easy opening tab including a portion adapted to slide between closed and opened positions over the dispensing aperture includes a flip-over finger engageable portion which is double-backed over the sliding portion when the tab is in the closed position. A closure panel puncturing projection extends from the flip-over portion of the tab so as to engage the partially pre-formed vent hole when the flip-over portion is pivoted to a substantially upright position. The continued pivoting of the flip-over tab to a flattened position on the end panel opposite the dispensing aperture and the interaction of the puncturing projection of the vent hole opening, slides the sliding portion of the tab to a position opening the dispensing aperture.
