发明名称 Tamper-evident dispensing closure
摘要 A dispensing package having a tamper-evident dispensing closure. A tamper-indicating removable strip is integrally formed with the closure and is secured to one of the closure body and closure cover via frangible bridging means. The closure hingedly connects the cover and body. The body defines a dispensing orifice and the cover seals the orifice. The strip defines spaces and the other one of the body and cover defines projections which extend into the spaces to resist relative movement of the body and cover unless the frangible bridging means are severed and thereby shows that access has been gained to the dispensing orifice. The closure is preferably generally circular and the tamper-indicating means are preferably within the perimeter of the closure.
