ABSTRACT:
A container closure includes a body for mounting on the container. The body defines two spaced-apart surfaces and a dispensing orifice between the top surfaces. A flow control device, such as a lid or nozzle assembly, is disposed on the body between the two spaced-apart top surfaces for being moved between positions opening and closing the dispensing orifice. A tamper-indicating member is provided over the lid or nozzle assembly. The member has two spaced-apart outer sections which are each attached to one of the body top surfaces. The member also has a middle section extending across and over the lid or nozzle assembly. The middle section is joined on each side with a frangible web to an outer section to inhibit movement of the lid or nozzle assembly from the closed position. The tamper-indicating member also includes a graspable pull tab on the middle section. The tab can be pulled to tear the middle section away from the outer sections along the frangible webs for permitting the opening of the lid or nozzle assembly and for providing evidence of tampering with the closure.
