This invention relates to a laundry device and method of use thereof, more particularly to a laundry device for protecting the visor of a baseball-type cap (hereinafter “ball cap”) from destructive contact with water during laundering and from destructive contact with solvent systems during commercial dry cleaning.
Ball cap users are generally disappointed by the appearance of a ball cap after laundering in a clothes washer or dishwasher, particularly the visor portion, alternately known as a brim or bill, which is generally stiffened with cardboard and/or other solvent-sensitive fillers. Contact with water deteriorates cardboard and other stiffening materials, such as fillers and starches, resulting in loss of turgidity and agglomeration of material so that the ball cap visor becomes less useful as a sun guard and unsightly. For these reasons, ball cap wearers shun laundering their ball caps despite obvious soil from perspiration and hair oils. Even hand laundering provides a disappointing appearance because contact of the visor with water is virtually unavoidable.
Dry cleaning fluids contain organic solvents that may degrade the visor stiffening materials so that repeated dry cleaning may result in a disappointing appearance and generally is less effective for removing perspiration than water-based laundry fluids. Moreover, dry cleaning fluids may contain water, such as from humid ambient conditions, which may contribute to deterioration of stiffening materials like cardboard that are water sensitive.
Accordingly, it is an object of the present invention to provide a laundry device to solvent-proof the visor of a ball cap during cleaning and a method of use thereof that is effective to prevent the visor from contacting water during machine and hand laundering with water and water-based laundry fluids, and during commercial dry cleaning with solvents that may contain water or other substances that degrade the visor.
The object of the present invention is accomplished in a first embodiment by providing a laundry device to solvent-proof a visor of a ball cap to be cleaned with a solvent, including at least one compressible sheet that is solvent resistant, each compressible sheet of the at least one compressible sheet being configured to contact and cover at least a portion of at least one side of the visor continuously from side to side at least proximate to an inner perimeter portion of the visor that faces and extends from a crown of the ball cap; a first plate and a second plate configured to sandwich the at least one compressible sheet and the visor therebetween, the first plate and the second plate having respective inner perimeter portions that face the crown, having respective outer perimeter portions that extend beyond the visor, and each having a shape that accommodates the visor but is larger than the visor at least along the outer perimeter portions thereof; and at least one attachment member that engages the first plate and the second plate to join the first plate and the second plate and to compress the at least one compressible sheet around the visor so as to provide a solvent-tight engagement of the laundry device around at least a portion of the visor.
