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 or across the container opening and positive indication to consumers of tampering with the seal. The seal system comprises the combination of indicia specifically placed on the container and a seal means in the form of a heat shrink band or a foil sheet applied to the container in a manner so as to temporarily obscure the indicia. In a first embodiment the indicia is applied to the container in an area below the neck and the seal means comprises an opaque band adhered to the container and closure over the juncture of thereof and over the indicia. In a second embodiment, the indicia is applied to the lip around the container mouth and the seal means comprises a foil sheet adhered to the lip and covering the mouth. A third embodiment combines the two individual forms into a double seal system comprising the inner foil sheet and indicia and the outer opaque band and indicia.
A tamper evident seal system comprising, in combination, a container having an open mouth, a closure adapted for removable engagement with said container over said mouth, and first and second independent tamper evident seal means applied to said container wherein said first tamper evident seal means comprises first warning indicia printed on said container at a location below said closure and a band of opaque heat shrink material applied about said closure and said container and having a length to extend beyond the location of said first warning indicia whereby said first warning indicia is temporarily covered and obscured by said band when said band is applied, and wherein said second tamper evident seal means comprises second warning indicia printed on a circumferential lip of said container mouth and an opaque foil sheet peelably adhered to said container over said mouth and said second warning indicia, whereby said second warning indicia is temporarily covered and obscured by said sheet when said sheet is applied, whereby said first and second warning indicia, when exposed by removal of said opaque band and sheet, signify that said seal system has been tampered with.
A tamper evident seal system comprising, in combination, a container having a neck portion comprising a lip surrounding an open container mouth, a closure adapted for removable engagement with said neck over said mouth and two independent tamper evident seal means, wherein a first tamper evident seal means is located between said mouth and said closure and comprises a first warning indicia printed on said lip of said container and a removable opaque foil sheet adheringly applied over said mouth and said lip of said container whereby said first warning indicia is temporarily covered and obscured, and a second tamper evident seal means is located over said closure and said container and comprises a second warning indicia printed on said container below said neck and a removable opaque band placed over and closely engaging said container and closure whereby said band extends over said container and closure whereby said second warning indicia is temporarily covered and obscured.
