This is a black ribbed non child resistant certified cap with a neck size of 33MM. This cap has a PS22 printed top gate liner.

A PS22 liner is made of .020”thick polystyrene foam disc with an EVA-wax type adhesive that is released when the closure is properly torqued onto the container. The liner is designed to stay in place even after the cap has been removed. These liners will adhere to both plastic and glass bottles and jars. These liners provide a one-time seal to be removed by the end user. The benefit of this type of cap is that no secondary equipment is required to apply them.

While these seals when properly applied can create a moisture barrier for keeping products inside dry, they are not considered by the FDA to be tamper evident.
