Abstract
The invention relates to a tamper-evident closure cap for a container having a neck and an opening defined in the neck. The closure cap of the invention includes an annular skirt member adapted to be secured to the neck of the container to prevent removal of the closure cap from the container, and a closure member hingedly connected to the skirt member for pivotal movement between a closed position whereat the closure member closes the opening of the container and an open position whereat the closure member permits access to the opening. A manually graspable tab is fixedly connected to the closure member for moving same from the closed position to the open position. The closure cap further includes a tamper-indicating member removably connected to the skirt member in overlying relation with respect to the tab and adapted to prohibit initial opening of the closure member prior to removal of the tamper indicating member. Thus, unauthorized removal of the tamper-indicating member provides evidence of tampering or initial opening.
