Abstract
A tamper-evident closure and specially shaped container neck. The closure has an upper skirt with an engagement structure on the interior of the skirt which cooperates with an engagement structure on the neck. The closure and neck have tamper-evidencing portions which interengage when the closure is seated on the neck to prevent removal of the closure with the tamper-evidencing portions intact. A tear tab reinforced with a vertically extending bend is joined to the tamper-evidencing portion of the closure. The neck has at least one notch shaped and positioned to receive the tear tab when a cap is applied to the neck.
