a) Field of the Invention
The present embodiment relates to the field of apparel, and or particularly to the class of apparel including panty hose nylon stockings and other items of hosiery. Also, it relates to a device and process for preserving the usable life of hosiery.
b) Background Art
A general description of the use of hosiery, stockings, or nylon type material will be briefly discussed. Stockings, hosiery, or tights, made of nylon and/or spandex, are coverings used by women to fit the body from the waist to the feet.
Hosiery is worn by women for many reasons. The stockings can enhance the curve of the legs through the sheerness, making the legs look smoother. They can also outline shape of the leg through the use of dark colors. The stockings also can provide warmth in colder weather.
Stockings come in a wide range of styles which generally relate to thickness and color. The thinner the stocking the shearer or finer the smoothness of the leg appearance.
Congruent with the thinness, is the likelihood that the stocking will develop rips or tears because of the thin structure of the weave.
The stocking weave is generally composed of nylon fibers and/or spandex fibers. The spandex provides the elasticity, while the nylon provides some elasticity as well as the thinness of the structure. The tearing or running of the stocking is most common with a higher content of nylon and a thinner structure.
The nylon and spandex fibers as stated before have a certain amount of elasticity which corresponds to a certain linear distance the fiber can be stretched without leading to permanent deformation.
When not in use, the nylon and spandex fibers of the hosiery are in a nonelastic state of use. When the user puts on the nylon stockings, the nylon and spandex fibers are stretched to fit the outer circumference of the user's leg. Although the nylon or spandex fibers are still within the elastic range, the cross-sectional area of the stretched fibers has decreased and is more susceptible to failure due to the transverse force as applied by a sharp object of some sort. This transverse force from a sharp object will likely cause a hole in the hosiery, which occurs where one or more of the nylon or spandex fibers has failed causing the elastic tension force within the failed nylon or spandex fibers to be transferred to the surrounding non-failed fibers.
Even though the tear or hole may start in a number of different ways, once it has started it is difficult to prevent the tear from continuing further. To prevent this tearing, there have been a number of solutions provided. One is to use off the shelf nail polish when generally applied at the apex of the tear or at the point where the tear is about to continue will help stop the tear.
The applicator itself may not be configured to apply a uniform and consistent amount of nail polish onto the tear. Also, nail polish takes time to dry. Much of the solution may not adhere to the material because the stocking itself is thin and not very absorbent.
Consequently the application of the nail polish liquid needs to be uniform and consistent, reinforcing the surrounding fiber structures, and if possible, breaching the failed fiber members to provide a patch to enable supplemental transferring of the tension load across the breached portion and also providing additional reinforcement to the surrounding fiber members.
The following patents are related to the problem of fixing or preventing hosiery tears.
U.S. Pat. No. 5,338,784 is directed primarily to the particular composition which is used as the repair liquid. The composition contains nitrocellulose, resin, another ingredient, and also a solvent. In column three (3) beginning on line 7 and following, it states that it could be stored in a jar with a brush, a roll-on bottle, any type of bottle, etc.
U.S. Pat. No. 4,994,127 describes a method of mending runs, snags, holes or the like in hosiery where there is “one-shot application container” containing the liquid adhesive ingredient. It also indicates that decorative material such as dyes, glitter, etc. could be used.
U.S. Pat. No. 5,087,496, shows a self-adhesive device which is attached to the damaged hosiery by Velcro means.
U.S. Pat. No. 4,068,322, discloses an adhesive patch that is placed on either side of the damaged area to prevent further damage.
In addition, a search of the internet uncovered a site that calls itself “PANTYHOSE ENCYCLOPEDIA”, which contains the statement, “The Miracle Against Runs! Just put some nail polish around the run and your pantyhose is saved.” Also, there was uncovered a New York Times publication concerning the care of pantyhose and the five (5) pages of that article are provided in the prior art statement.
In discussing the detailed description of the current embodiment it is preferable to first provide a detailed description of the structure and function of the nylon fabric, thus providing a clear understanding of the current embodiment environment.
With this in mind, a detailed description of the fabric structure and function will be provided, followed by a detailed description of the current embodiment of the hose run stopper method and apparatus which includes the apparatus container or applicator, its application elements, and the binding composition which when applied, reinforces the nylon fabric. Lastly, additional embodiments of the applicator elements will be provided.

Although the run or tear 16 caused by the snag on the object may be unnoticeable because of the relatively fine weave of the hosiery 14, once the balanced structure has been disturbed, a tear 16 will quickly develop, and for reasons discussed below, the tear may irreparably harm the hosiery 14, making it unusable.

The weave of the stocking will now be discussed. Referring to
After the snag has occurred, and still referring to
The tear 16 has parallel longitudinal border fiber members 49 as well as two apex points 47 at the beginning and end of the tear 16. It is at the apex point 47 where the elastic tension force 32 residing in the circumferential fiber members 30 pulls the connected longitudinal fiber members 36 apart and continues the tear 16.
Now describing in particular the tearing or ripping action. As the longitudinal fiber members 36 are pulled away from their existing longitudinal location towards the parallel longitudinal border fiber members 49, the circumferential fiber members 30 are transitioning from the tension state to the untensioned state and act on this longitudinal fiber member 36 to create a resultant angular tension member 42 pulling on the individual circumferential fiber members 30 at the apex point 47 of the tear 16.
Referring to
This resultant tension force 42 has a longitudinal tension component 40 and circumferential tension component 38. For calculation purposes, we will assume that the circumferential tension component 38 is one half of the tension force 32, while the longitudinal tension component 40 is some other force amount which results in combination with the circumferential tension component 38 to produce the resultant angular tension force 42 as shown.
The origin 33 of this resultant angular tension force 42 is the intersection, or connection of the longitudinal fiber members 36 and the circumferential fiber member 30. Simplifying the force diagram, and referring to
This series of chain reaction failures of the fiber members can occur gradually or nearly instantaneously, depending on the size of the user's leg as well as the flexing of the user's muscle, thus increasing the circumferential distance and increasing the circumferential tension force, stressing the fibers beyond their elastic range.
Therefore, it is desirable to have a solution or composition contained within an applicator, which when the solution is applied to the tear 16, binds to the fiber members, reinforcing them at the weakened stress point, as well as drying or binding quickly to the fiber members.
Also, it is highly likely that the user is wearing the hosiery to work or at a social function, and needs an applicator which can provide accuracy of the application of the binding solution to the tear, as well as convenience in use.
Therefore the discussion of the current embodiment acting in the above described nylon hosiery environment will first describe the elements of the applicator, followed by the elements of a typical binding solution, and lastly, additional embodiments of the applicator will be discussed.
The solution applicator 10, as referred to in
Still referring to
At the top portion of the solution applicator 10 is an application head 60 which is fashioned in the current embodiment, from a porous or sponge like material. In the current embodiment, the sponge like material is a commercially available material with a porous cellular structure large enough to carry the solution and be sufficiently compressible to discharge the solution. This sponge like material is well-known in the art and is used commercially in many different applications. Use of the sponge like material allows the binding solution 58 contained within the solution applicator 10 to migrate up through the application head 60 and be absorbed into the cells of the material for application.

By using the flat top application surface 66, the user a more uniform application which could compromise the effectiveness of the applicator. In contrast, a user could use an edge of the application head to be more specific in the application of the solution to the nylon tear.
A sealed environment to keep the solution in the containing region from escaping is desirable. Referring back to
For reasons discussed below, the binding solution has an alcohol-based content, and will readily evaporate. Therefore, to keep the absorbed binding solution 58 from evaporating and thus binding within the porous elastomer material 60, a closure cap 62 is provided to create a hermetically sealed environment thus preventing the binding solution from evaporating out of the cylindrical shell inner region 53.
An additional embodiment of this solution applicator 10 is that the inner region 53 of the cylindrical shell 50 is nearly 100% hermetically sealed from the outside environment when the cap 61 is attached over the application head. When initially used, the inner region 53 is completely full of binding solution 58. After a period of time, there becomes a void or air space within the inner region 53 due to the consumption or use of the solution.
Thus, the binding solution 58 contained within the inner region 53 will not take up the entire volume of the inner region 53, thus leaving a volume space for potential evaporation. A vapor volume region 61 will develop, and become filled with a combination of air and evaporating binding solution vapor. This combination of air and binding solution vapor will act to mitigate any hardening of the binding solution 58 on or in the cellular structure of the sponge like material as well as within the cylindrical shell 50 itself. Similarly, when the solution applicator cap 62 is on the solution applicator 10, virtually no airspace is left between the cap top 65 and the top application surface 66. What little airspace there is left will be filled with a mixture of oxygen and binding solution vapor, and the evaporation rate of the binding solution from the top application surface 66 will balance out to nearly zero, thus keeping the application head 60 moist with the binding solution 58.
In this particular embodiment, the cylindrical cap 62 has a height substantially great enough to cover the application head 60 and be secured to the outer wall of the cylindrical shell 49 through one of many securing means. One such securing means is a screw type cap with grooves fabricated into the cylindrical shell outer wall 49 and corresponding grooves inside the cylindrical cap 62.
A brief discussion of the application process of the binding solution 50 to the hosiery 14 will now be provided.

After the application process has been performed, the binding solution 58 will harden around the individual fiber members adjacent to the tear zone and reinforce the fiber members within the path of the tearing chain reaction to resist the additional tension and shear forces.
A detailed description of the fiber members as reinforced by the binding solution will now be provided.

Referring to
By using a uniform top application surface 66 during application of the binding solution, the user can be assured a uniform amount of solution is applied to all of the surrounding fiber members, thus providing uniform reinforcement and distribution of the load around the apex 47 of the tear 16.
A detailed description of the binding solution 58 will now be provided. The binding solution 58 should have characteristics which include elasticity for stretching along with the nylon fiber members, binding properties to attach to the nylon fibers, and a high rate of evaporation so as to minimize wait time. The physical characteristics of the binding solution 58 can be composed of a natural resin which dries to a hard but flexible and durable compound after application. This compound can easily bind with the fibers in a nylon or spandex and nylon hosiery stocking.
The current embodiment of the binding solution 58 is comprised of four parts of a commercially available nail polish compound and one part of a thinning solvent. In this embodiment, the four parts nail polish compound has the following chemical composition by percentage of weight.
Additionally, in this embodiment the one part thinning solvent has the following chemical composition by percentage of weight.
Lastly, in combination the binding solution 58 from four parts Nail Polish compound, and one part thinning solvent, has the following chemical composition by percentage of weight.
For reasons discussed above the application of this binding solution to the nylon stockings 14 around the tear 16 from the snag as shown in
