Abstract
A shield unit, intended primarily for the protection of a carpet from the accidental application of paint applied to an adjacent baseboard, and suitable for disposable use, consists of two superposed plies of a film, comprised or consisting of a plastic material, which cooperatively define a plurality of adjacent pockets and have a common, structurally reinforced leading edge. The shield unit is long and narrow, and is constructed to facilitate entry of its leading edge into the effective gap that is normally present between the bottom of a baseboard and a carpet on the floor; the pockets serve to receive the blade of a tool, such as a putty knife, to which force may be applied to assist in pushing the leading edge of the shield into the effective gap. The shield unit may be provided as individual, relatively short sections, typically at least 30 inches long and four inches wide, or longer units may be used to cover an extended length of carpet with a single section. A multiplicity of shield units may be cut or otherwise separated from a continuous length strip, typically at least eight feet long, which may be provided in the form of a roll or a folded stack.
