Abstract
A combination cap and handle for use with a detachable humidifier reservoir tank. Extending through the cap is a tubular aperture containing a biased plunger that interacts with a base pin in the water receiving portion of the humidifier. The plunger is attached to a flap such that when the reservoir tank is placed into the body of the humidifier, the plunger and flap are urged into the reservoir tank, allowing the water in the reservoir to fill the humidifier. Extending radially from the plunger aperture on the external surface of the cap are raised handles. These handles allow for a mechanical advantage when the user wishes to remove the cap from the reservoir, or to transport the reservoir more easily both when full and when empty.
