ABSTRACT:
A closure is provided for a container and includes a base. The base includes a body for mounting to the container, and the body defines a dispensing orifice. A tamper-evident seal initially closes the dispensing orifice. The seal has a removable central portion occluding the orifice and at least a first frangible web defining a closed tear path lying in a plane connecting the seal central portion to a surrounding part of the closure. The seal central portion includes a hollow projection having a base located in the plane with one part of the base closer to the first frangible web than is any other part of the base. An outwardly directed force of sufficient magnitude applied to the projection will produce a tear which extends through the first frangible web at a point on the first frangible web closest to the one part of the projection base. The tear thereafter propagates from that point around the seal central portion so as to separate the seal central portion from the closure and thereby open the seal.
