A dual function cap member for a necked container having a material dispensing opening and a closure seal membrane securely attached thereover. The cap member is double sided and reversable. One side of the cap member has means coactable with the container neck to form a container closure cap. The reverse side of the cap has closure seal membrane piercing means operative, upon removal and reversal of the cap member from the closure cap position, to pierce and spread open the central area of the membrane. A peripheral portion of the so-pierced and opened membrane remains securely attached to the container neck about the dispensing opening for continued attachment of the membrane material to the container neck. The cap member, subsequent to membrane piercing, and possible dispensing of material from the container, is again operative, upon reversal, to serve as a selectively removable container closure cap to close and seal the dispensing opening.
