Abstract
A closure structure for a container includes a body having a containing wall for closing the container, the containing wall having a dispensing orifice. A lid is operatively associated with the containing wall to cover the dispensing orifice in a closed position and uncover the dispensing orifice when the lid is moved away from the closed position. In one embodiment, a tamper-indicating member includes a press portion connected by a hinge to the lid, and an anchor portion connected to the body, the press portion connected at a frangible junction to the anchor portion, whereby the press portion can be moved sufficiently relative to the body to separate the press portion from the anchor portion. The anchor portion is connected to the body by an anchor member extending radially from the body. The anchor portion includes an aperture. The body includes a radially extending head which captures the aperture when the anchor portion is pressed to the body. The head can be flattened to make the connection between the anchor portion and the body more secure.
