The strap includes a plug for occluding a dispensing hole in the closure body portion and may include a projection for anchoring the strap to the closure body portion through another hole. A vent tube may be provided through the anchoring projection. For providing tamper indication, an orifice-defining anchor portion may be mounted in the dispensing hole of the closure body portion and connected via a frangible web to a retaining member overlying a portion of the strap.
