Tamper proof flip top cap

摘要

A tamper evident flip top pouring closure is designed for use with a corresponding container. A tamper evident flip top pouring closure and container in combination has a closure with a screw thread thereon together with interlocking means and a container with the corresponding screw thread and corresponding interlocking means. The interlocking means prevents the removal of the closure from the container once the closure is installed on the container. The interlocking means on the closure are a series of tabs that are connected to the closure and extend inward at an angle. The interlocking means on the closure are two sets of saw-teeth having a gentle slope on one side and a steep slope on another side. The closure is then installed on the container and cannot be removed because the tabs abutt a steep slope of the saw-teeth and will not override the saw-teeth in a reverse direction.
