Abstract
Abstract A disposable spray shield has a thin, planar sheet of large surface area fabricated with an inexpensive, semi-rigid material, such as cardboard, formed with a structural reinforcing rib along its rear edge. The rib can be used as a handle in combination with a hand hole through the sheet adjacent the rib, or, preferably, a removeable handle is included for removeable attachment to the disposable spray shield. The rib is preferably formed from a portion of the planar shield sheet folded into an elongated, three-dimensional configuration and the handle has clamping jaws and mating surfaces that engage the rib. Disposable handles are also provided as an alternative.
