The combination of a container and a safety cap therefor in which the safety cap has a closure plane and a circumferential outer skirt for engaging a container and has a circumferential resilient depending inner member. The container has a rigid wall having an end for engagement with the cap internally of the outer skirt. The wall is tapered from a smaller diameter portion adjacent the closure plane of the cap to a larger diameter portion remote from the closure plane of the cap. The tapered wall of the container engages internally the resilient inner member of the cap and the larger diameter portion of the wall expands the resilient inner member outwardly to provide a working seal of the container as well as a bias on the cap in a direction of removal of the cap. The combination also includes means disposed on the container remotely from the end of the rigid wall and cooperative means on the cap for preventing the cap from being removed from the container without depression of the cap on the container and rotation of the cap on the container. When the container is used as a bottle, the container preferably includes means for providing a tamper evident seal, whereby it will be obvious that the contents have been sealed with a material protecting the contents of the container. Any penetration of the seal prior to the removal and destruction of the seal by the user will be evidence of the lack of integrity of the contents of the container.
