Abstract
Abstract A fluid refill pouch for use with a dispenser having a refill well with a refill opening therein and a piercing member disposed in the refill well, the pouch having a flexible wall hermetically sealed for containing fluid, and a docking adaptor loosely disposed in the pouch for insertion into the refill well so as to push the wall of the pouch upon the piercing member to pierce the wall and provide an opening for discharge of fluid from the pouch through the refill opening and into the dispenser; the inner wall of the refill well and the outer wall of the docking adaptor are shaped complementarily with flutes in the outer wall of the docking adaptor for easy grasping by the user, the parts having non-standard dimensions to provide anti-bootleg protection; there also is provided a fluid dispensing system incorporating such a refill pouch and dispenser.
