a material - economizing , tamper - evident seal is disclosed having dual , non - contiguous , symmetrically placed , reusable catches and a tear - off identification tag . should seal replacement become necessary , the seal &# 39 ; s identification tag is first torn off , and then the remainder of the seal is passed through one of the catches . a replacement seal with its own identification tag may then be engaged with both of the catches . the invention &# 39 ; s preferred embodiment allows easy rotation of the identification tag , thus facilitating inspection of the tag &# 39 ; s identifying mark , typically a serial number . the tag &# 39 ; s tear - off feature is effected by the presence of an abscission bead , which may take one of several forms , as , for example , a row of perforations . whereas some of the invention &# 39 ; s components are preferably molded out of a resilient and relatively weak , thermoplastic material such as polypropylene , other components may with advantage be molded out of a much - stronger material , such as polycarbonate , instead .
