Disposable spray shield |
摘要 |
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 creased and folded into an elongated configuration having an equilateral triangular cross-section, and the handle has clamping jaws and mating surfaces that engage the rib to orient the axis of the handle parallel to the plane of the shield or, alternately, at an obtuse angle to the plane of the shield. Disposable handles are also provided as another alternative.
