Background of the Invention
The field of this invention relates to those articles specifically designed to deter perspiration from obstructing the vision of the safety hat wearer during the performance of his or her duties.
Specific fabric selected for this design will have unique absorption qualities. One side of the fabric is unfused or bearded, while the other side of the fabric is fused. When moisture is introduced to the unfused or bearded side of the fabric, the moisture is absorbed and penetrates through the fused side. The fused side of the fabric does not allow the moisture to return to the unfused side. In this application, the unfused or bearded side of the fabric will be placed in such a manner that it will form the outside of this moisture-absorbing (perspiration) invention.
With the addition of the layers of absorbent padding between the top and bottom layers of above described fabric, the disposable sweat liner will retain more moisture or perspiration thereby reducing the frequency of changing and replacement of the disposable sweat liner.
The two outside layers of fabric, with the layers of absorbent padding between, are then heat-sealed around the edges with pressure-sensitive adhesive tabs attached by the same heat sealing process.
Previous inventions in this field would not be as efficient or sanitary as the one herein described because of:
1. The type of materials used in previous inventions, when saturated with perspiration, will not retain the perspiration, thus allowing the perspiration to fall into the wearer's eyes which defeats its purpose.
2. The materials in previous inventions tend to be bulky and uncomfortable to wear.
3. The design of the previous inventions would require laundering every day or during the summer months, several times each day.
4. The method of attaching the previous inventions to the headbands of the hard hats is cumbersome and time-consuming.
The disposable sweat liner for safety hats described in the application would be the solution in that it alleviates the four problems in the foregoing paragraph.
Summary of the Invention
More and more industries are requiring their employees to wear safety hats or as they are more commonly called, "hard hats" in the performance of their duties. The hard hats must fit on the head in such a manner that perspiration will form around the existing headband of the hard hat and especially in the region of the forehead.
The principal object of this invention is to provide a functional yet inexpensive disposable device which will, because of its design and its component parts, absorb and retain perspiration effectively on the forehead of the wearer.
Another object of this invention is to protect the area of the brow and forehead where it comes in contact with the headband and webbing of the hard hat.
Another object of this invention is to absorb the perspiration of the wearer especially those working with high voltage electricity or heavy industrial machinery where obstructed vision caused by perspiration or pausing to clear the perspiration from the eyes could cause a serious accident or injury.
Another object of this invention is, because of its component parts, it will retain the perspiration.
A further object is its simplicity of design and ease of application to the hard hat, having only three pressure-sensitive tabs to attach to the headband of the hard hat.
A still further object is that the wearer doesn't have to be concerned with washing or otherwise cleaning and storing this design.
Other objects include simplicity of design, ease of use, inexpensive to manufacture and to purchase, and very efficient all of which will become apparent as the following detailed description is read in conjunction with the accompanying drawing.

Detailed Description of a Preferred Embodiment of the Invention
FIG. 1 indicates the configuration of the disposable sweat liner (5) prior to the application inside the safety hat noting the location of the three pressure-sensitive adhesive tabs (4) and that portion of said pressure-sensitive tabs to which pressure-sensitive adhesive material (8) has been applied.
Referring to FIG. 2, the disposable sweat liner (5) prior to actually securing to the existing headband (1) of a safety hat and indicating the relationship of an disposable sweat liner (5) to the existing headband (1), and to the existing webbing (2) typically found in a safety hat (3).
Referring to FIG. 3, the disposable sweat liner (5) is placed inside a front center portion of the headband (1) of the safety hat in such a manner that the pressure-sensitive adhesive tabs (4) carrying adhesive (8) are inside and adjacent to the existing headband (1), with a wider, trapazoidally shaped pressure-sensitive adhesive tab being positioned inside the front center of said headband causing the two narrower pressure-sensitive adhesive tabs to be positioned inside and on either side of the headband approximately above the wearer's temple. The bottom edge of the sweat liner (5) is positioned even with the bottom edge of the sweat band (1) in the safety hat.
Each of the pressure-sensitive adhesive tabs (4) is then be pulled under the existing sweat band (1), over the outer side of said sweat band and attached to the disposable sweat liner.
The top portion of the disposable sweat liner (5) is held in place by the wearer's forehead and the existing webbing (2) in the crown of the safety hat (3) as shown in FIG. 4 and FIG. 5.
FIG. 4 is a top plan view of the application of the disposable sweat liner (5) and the relation of said disposable sweat liner (5) to the headband (1) and crown webbing (2), FIG. 6 indicating a cut-away version with safety hat (3).
As shown in FIG. 5 a cross-sectional view of the disposable sweat liner, the sweat liner contains layers of absorbent padding (7) covered on the top and bottom by fabric (6). The outside covering of fabric (6) is assembled in such a manner that one side (6a) of the unfused or bearded side of the fabric will be that portion of the disposable sweat liner (5) which comes in contact with the wearer 3 s forehead and the other side 6b is the side facing inwardly toward the layers of padding.
It will be recognized that the foregoing is but one example of an apparatus and method within the scope of the invention and that various other modifications will occur to those skilled in the art upon reading the disclosure set forth herein before.
