Abstract
Two cap modifications are disclosed for use on water bottles to be installed in water dispensers. A central conical well in the top of the cap is formed with a scoreline. When the bottle is lowered into a dispenser, a probe of the dispenser enters the well and causes it to split along the scoreline. When the bottle is raised, the well substantially returns to initial condition, inhibiting spillage of any liquid remaining in the bottle.
