Abstract

Protective covers and methods of manufacturing same. One such cover comprises a composite sheet having a first end, a second end, a first lateral edge extending between the first and second ends, a second lateral edge extending between the first and second ends, and an axis extending between the first and second lateral edges. First and second panels of the composite sheet each comprise a substrate formed from a nonwoven material, a first layer of plastic film disposed on the substrate such that at least a portion of the first layer is slidable relative to the substrate; and a second layer of plastic film disposed on the substrate such that at least a portion of the second layer is slidable relative to the substrate. The composite sheet is folded about the axis and a partially enclosed space is defined between the first and second panels.

A cover for protecting an object, the cover comprising:

a first panel having a first end, a second end, a first lateral edge extending between the first end and the second end, and a second lateral edge extending between the first end and the second end, the first panel comprising:
a first layer of nonwoven material, the first layer of nonwoven material having a first surface and an opposite second surface;
a first layer of plastic film adjoining the first surface of the first layer of nonwoven material;
a second layer of plastic film having an interior surface adjoining the second surface of the first layer of nonwoven material;
and
a third layer of plastic film coupled with an exterior surface of the second layer of plastic film;
a second panel having a first end, a second end, a first lateral edge extending between the first end and the second end, and a second lateral edge extending between the first end and the second end, the second panel comprising:
a second layer of nonwoven material, the second layer of nonwoven material having a first surface and an opposite second surface;
a fourth layer of plastic film adjoining the first surface of the second layer of nonwoven material;
a fifth layer of plastic film having an interior surface adjoining the second surface of the second layer of nonwoven material;
and
a sixth layer of plastic film coupled with an exterior surface of the fifth layer of plastic film;
wherein the first panel is disposed with respect to the second panel such that the first layer of plastic film of the first panel is in facing opposition to the fourth layer of plastic film of the second panel;
a first coupling between the first panel and the second panel, the first coupling located proximate the respective first lateral edges of the first and second panels;
a second coupling between the first panel and the second panel, the second coupling located proximate the respective second lateral edges of the first and second panels;
and
an opening defined between the first and second panels proximate the respective first ends of the first and second panels.
