ABSTRACT:
A child resistant container construction. The dispensing opening of the container is normally closed by a plug having a pull tab thereon. The plug is removable and reinsertable in the dispensing opening. The plug is formed so that it is distortable. A rigid, rotary locking member is carried by the plug. In one angular position on the plug, the locking member prevents distortion of the plug and thereby prevents plug removal. In a second angular position on the plug, the locking member permits distortion of the plug upon pulling the pull tab, thereby permitting its removal from the dispensing opening. In other embodiments, the locking member can be completely removed from the plug to permit plug distortion and removal.
