Abstract
Abstract A lightweight cover for a shaped object such as an automobile for protecting the object from the environment comprising a plurality of panels of lightweight, impermeable sheet material having the edges joined to form an enclosure. The sheet material is preferably a laminate of a film of reflective metal between an outer layer of transparent resin such as Mylar or polyethylene and an inner layer of resin, preferably color coded. The laminate may optionally contain a layer of scrim reinforcement. Water trapped between the cover and the surface of the object is selectively exhausted by means of vents having a flap which opens in response to gas pressure developed on evaporation of the trapped water vapor and normally remains closed to prevent entry of rain, dust, sap or other substances harmful to the finish of the automobile stored under the cover.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
93 words
A lightweight, protective cover for a shaped object comprising: a plurality of panels of lightweight, vapor-impermeable, sheet material; means securing the edges of the panels to form an enclosure; at least one vent opening in the enclosure formed by overlapping two edges of adjacent panels, and flap means formed by intermittently forming a series of spaced lines connecting the overlapped portions of the panels whereby entry of water from the outside surface through the vent opening is prevented while water vapor can be selectively exhausted through the openings between the lines of attachment.
Claim 2
Dependent Claim
93 words
