Tamper-resistant cap for a container |
摘要 |
A cap is provided for mounting on a necked-in can. The cap includes a shell formed to include an interior region and a tool-receiving aperture opening into the interior region. A ridge is appended to the shell and positioned to lie in the interior region of the cap. The ridge includes a downwardly facing ridge edge that lies inside the interior region of the cap and adjacent to the tool-receiving aperture. The ridge edge overlies a portion of an annular lip of the necked-in can when the cap is mounted on the can so that a cap-removal tool can be inserted into the interior region of the shell through the tool-receiving aperture simultaneously to engage the annular lip of the can and the ridge edge. When the cap-removal tool is rotated manually about its longitudinal axis, the cap-removal tool acts between the ridge edge and the annular lip to demount the cap from the necked-in can.
