A tear skirt is removably attached to the annular depending flange, the tear skirt having a pull tab for the removal thereof. An out-turned annular flange is formed on said tear skirt and a plurality of circumferencially placed gussets join said angular flange and said tear skirt. The closure has dual fastening configurations, either one of which is capable of holding the closure on the neck portion of the container.
