ABSTRACT:
A flip-top type tamper evident closure for dispensing material from a container includes a body portion having a dispensing opening, a lid portion hingedly connected to the body portion and a tamper evident band that is frangibly connected to the body portion. The tamper evident band is constructed and arranged to engage structure on the lid portion in an interlock arrangement in order to retain the lid portion in a closed position prior to the closure first being opened by a consumer. Advantageously, as an additional security measure the tamper evident band is further lightly spot-welded to the lid portion, which prevents or makes evident any attempt to overcome the interlock arrangement. A method of making the closure is also disclosed.
