CA 2092369

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 comprises 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 provides access to the opening, the closure member having a top planar portion extending in a first plane. 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. The tamper-indicating member comprises a manually graspable tongue portion and at least one elongated attachment portion extending between the closure member and the skirt member and detachably connected to the skirt member, the tongue portion and the at least one attachment portion being co-planar and extending generally in the first plane. Thus, unauthorized removal of the tamper-indicating member provides evidence of tampering or initial opening. since, according to the invention, the tamper-indicating member is disposed in overlying relation with respect to the opening means, it is impossible for an unauthorized user to move the closure member from the closed position to the open position without first removing the tamper-indicating member and thus without providing evidence of tampering or initial opening.
