A tamper evident closure for use on a container neck, the closure including a cap and separately formed security device, connector means for attachment of the security device to the cap, the security device including anchor means disposed to catch beneath a shoulder as provided on the container neck when the cap is attached to the container neck, the connector means comprising a frangible joint adapted to rupture during removal of the cap from the container neck whereby to enable the security device to break away from the cap, the anchor means being engageable with the shoulder of the container for retaining the security device on the container neck when the cap is removed therefrom, the security device thereby evidencing that the container has been opened; and a method of manufacturing such tamper evident closure.
A tamper evident closure for use on a container having a neck provided with a mouth, cap retaining means and including a shoulder disposed below the cap retaining means thereof, said closure comprising a cap, a security ring formed disjunctively from said cap, and fused bridge means for interconnecting said security ring to said cap, said cap including retaining means adapted to cooperate with the cap retaining means of the container neck thereby to retain said cap on the container neck as juxtaposed for closing the mouth thereof, said security ring including anchor means disposed to pass over and catch beneath the shoulder of the container when said cap is juxtaposed on the container neck for closing the mouth thereof, and said fused bridge means comprise frangible zones of weakness adapted to rupture during removal of said cap from said container neck whereby to enable said security ring to break away from said cap, said anchor means being engageable with the shoulder of the container neck for retaining said security ring on the container neck when said cap is removed therefrom.
A tamper evident closure for use on a container neck provided with a mouth and retaining means and having a shoulder disposed below the retaining means thereof, said closure including a molded cap and a molded security device as formed independently of and separate from said cap, connector means for attachment of said security device to said cap, said cap including retaining means adapted to cooperate with the retaining means of the container neck whereby to retain said cap on the container neck as juxtaposed for closing the mouth thereof, said security device having a body portion extending circumferentially about said container neck and including anchor means disposed to catch beneath the shoulder of the container neck when said cap is juxtaposed on the container neck for closing the mouth thereof, said connector means comprising frangible joint means adapted to rupture during removal of said cap from said container neck whereby to enable said security device to break away from said cap, said anchor means being engageable with the shoulder of the container neck for retaining said security device on the container neck when said cap is removed therefrom.
A method of manufacturing a tamper evident closure for use on a container neck provided with a mouth and having a shoulder disposed below the mouth thereof, and wherein the tamper evident closure includes a cap configured to serve as a closure for the mouth of the container and a security device detachably interconnected thereto, the security device being provided with anchor means adapted to catch beneath the shoulder of the container neck for retaining the security device on the container neck when the cap is unloosened and removed from the container neck, the method comprising the steps of molding the cap, molding the security device independently of and separate from the cap, and interconnecting the cap and security device by connector means adapted to rupture during removal of the cap from the container neck whereby to enable the security device to break away from the cap and remain on the container neck when the cap is removed therefrom.
A tamper evident closure for use on a container having a neck provided with a mouth, cap retaining means and including a shoulder disposed below the cap retaining means thereof, said closure comprising a cap and a security ring formed disjunctively from said cap, and means for interconnecting said security ring to said cap, said cap including retaining means adapted to cooperate with the cap retaining means of the container neck whereby to retain said cap on the container neck as juxtaposed for closing the mouth thereof and a depending cylindrical skirt having a lower edge portion, said security ring including anchor means disposed to pass over and catch beneath the shoulder of the container when said cap is juxtaposed on the container neck for closing the mouth thereof and an upper edge portion, each said edge portion having guide means inset from the outer periphery thereof, one said guide means comprising female guide means, and the other said guide means comprising male guide means disposed to mate within said female guide means in juxtarelation to minimize side shear and separation of said security ring front said cap during assembly of one to the other, said means for interconnecting said security ring to said cap comprising zones of weakness adapted to rupture during removal of said cap from said container neck cap, said anchor means being engageable with the shoulder of the container neck for retaining said security ring on the container neck when said cap is removed therefrom.
