ABSTRACT:
A tamper evident seal and system for use on a variety of container and closure combinations providing a seal across the juncture of the container and closure and positive indication to consumers of tampering with the seal. The seal comprises a heat shrink band to which is applied at least one strip of a heat activated adhesive extending perpendicularly to the band's circumference and along the full length of the band. Perforations are provided along either edge to permit separation of the majority of the band from that portion to which the adhesive is applied. Indicia are provided on the band and on the container to indicate the presence or absence of the band. Application of the band to the container by heating causes the band to shrink into tight conformance with the container and closure obscuring the indicia thereon and bringing the adhesive into engagement with the container and closure. The heat activates the adhesive causing it to adhere that portion of the band to the container and closure across their juncture. Removal of the band will leave the adhered strip in place as a secondary safety seal and will expose indicia on the container to alert the consumer that the outer band has been removed and that the secondary safety seal should still be intact but must be broken to open the container.
