Description
it This invention relates to paint application.
More particularly this invention relates to a method of applying paint to a substrate for a "touch-up".
Touch-up application of paint to a substrate is normally a very difficult task to accomplish in order to obtain smooth effects which would allow the touch-up paint to blend smoothly into the paint on the substrate surface. Typically, to cover a scratch or a chip of paint on a substrate surface, a user is faced with a limited choice of how the scratch or chip can be repaired to provide adequate results which are not noticeable to the eye. Ordinarily, touch-up paint can be applied by means of pressurized spray cans of paint to the scratch or chip but, it is very difficult to control the amount of paint and the area being painted in order to provide a touch-up application.
In the case of pressurized spray cans, which normally direct their contents over a fairly wide area, it would be necessary to isolate the scratch or chip by means of a protective coating if one wanted to avoid overlapping of additional paint on the substrate surface surrounding the chip or scratch. Moreover, with pressurized spray cans, in trying to match the depth of the paint scratch or chip with the adjacent paint, several applications of paint from the pressurized spray can may be necessary.
Another alternative that is used in practice is to take a very small paint brush, such as an artist's paint brush, and to apply the paint to the scratched or chipped area. On one hand, the individual user can control the application of the ;

paint to the chipped or scratched location, however a big disadvantage with the use of bristles in such paint brushes is that the bristles tend to provide an uneven coating of the paint to the area or leave bristle marks on the substrate.
With this invention, applicant has developed a method of applying touch-up paint to a substrate, which overcomes the disadvantages outlined above, and which comprises utilizing as paint application means, a paint applicator comprising gripping means for gripping the applicator, absorbent means mounted on said applicator, and a covering layer of a polyurethane foam material enveloping said absorbent core, and applying a coating of paint to a desired substrate utilizing said foam polyurethane covering layer.
In greater detail of the present invention, applicant has found that for touch-up application of paint to scratches, chips or the like, the above type of structure provides a very smooth and effective coating touch-up paint on the desired area which is free from brush or bristle marks and which can be controlled to apply the desired amount of touch-up paint to the effected area. Thus, in the method of the present invention utilizing the above described applicator means, the disadvantages of spray painting for touch-up purposes can be eliminated - i.e., only the desired area for touch-up painting can be treated with paint without the necessity of having to protect or mask adjacent areas and conversely, the method of the present invention has the advantages of the manual method of applying touch-up paint in that the area being painted can be controlled manually but does not have the disadvantage of leaving bristle or brush marks ..

on the painted area.
The discovery of the fact that using a particular type of paint applicator according to the method of the present invention is believed to reside in the combination of the particular type of foam covering, namely a polyurethane foam, enveloping a core of absorbent material.
In carrying out the method, a preferred paint applicator comprises an elongated handle for gripping the applicator, which should be of a generally rigid nature and having at one end, absorbent means associated with the gripping handle which is enveloped by the polyurethane foam covering material. The absorbent material is preferably of a cotton swab type although other materials may be used for this purpose. The polyurethane foam covering preferably comprises a sheet or layer of flexible foam. This sheet or layer, in addition to forming the applicator surface for use in the method of the present invention, encloses the absorbent cotton material in a totally enclosed manner.
In one form of the present invention, suitable means are provided for securing -the polyurethane foam about the absorbent material, and preferably fixedly securing the same to the handle of the device. Such means may comprise a metal or plastic clip or alternatively an elastic band or even string to maintain the polyurethane foam covering in place.
Irving thus generally described the invention, reference will now be made to the accompanying drawings, illustrating preferred embodiments and in which;
~2~36~;~
Figure 1 is a perspective view of a touch-up applicator used in the method of the present invention; and Figure 2 is an exploded view of the components used in the touch-up applicator, for use in the method of the present invention Referring to the drawings, and in greater detail, the method of the present invention employs a touch-up applicator, such as the structure shown in Figures 1 and 2. Thus, handle means in the form of an elongated rod functioning as gripping means is provided; typically handle 20 will be made of a wood cylinder or alternatively, a plastic rod. Handle 20 preferably does not have a great degree of flexibility although in some applications, more flexibility than a "stiff" handle may be required.
Mounted about one end of handle 20 is an absorbent cotton swab 22 which.due.to the nature of the cotton fires need not necessarily ye secured to one end of the handle 20. If desired, however, a coating of adhesive may ye employed for retaining the cotton swab 22 in place. Typically, the cot-ton swab 22 may be a small sphere of cotton; this may be wrapped around the end of the handle 20 and extend from the handle outwardly so that there is a "free" portion but in most cases, the bulk of the cotton swab will be wrapped around the end of the handle.
The polyurethane foam covering is indicated by reference numeral 24 and comprises a flexible layer of foam material.
For ease of manufacture, as shown in Figure 2, a die cut circular shape may be employed which then can be wrapped around the ~;~253~~
absorbent portion of the structure as well as the handle 20, and secured at its end by means of, for example, a clip or band 26.
Typically, the polyurethane foam covering may range in thickness from one sixteenth of an inch to a quarter inch or more, depending on the particular application for which it is used.
As will be appreciated the method of this invention can be applied for a vast area of uses where touch-up application of paint is desired. Thus, for instance, scratches and chips can be easily touched-up or repaired on appliances such as refrigerators and stoves, on cars and trucks, furniture, walls, etc. The touch-up applicator may be used with both oil-based and water-based paint and provides paint touch-ups which will not crack, peel or fragment in normal use.
It will be understood that various modifications can be made to the above described embodiments, without departing from the spirit and the scope of the invention defined herein.
