Description

SILICONE-ELASTOMER FILM

Technical Field

The present application relates to thin-film silicone elastomers, methods of manufacturing thin-film silicone elastomers, and uses for such thin-film silicone elastomers.

Description of the Prior Art

Most handheld electronic devices, such as cellular telephones, camcorders, cameras, computer-based digital cameras, CD and MP3 players, PDA's, remote controls, notebook computers, tablet PC's, video games, video game controllers, hair trimmers and shears, and a wide variety of other handheld electronic devices, including carrying cases and pouches for these devices, have housings that are made of hard, smooth materials, such as plastic and metal. Although some of these devices include hand grips and/or small rubberized components, they typically do not include any anti-slip material over a large portion of their housings. This is a problem, because when a user handles one of these devices, the slightest amount of mishandling can allow the device to slip out of the user's hand, which can lead to the device being dropped and damaged. In addition, when these devices are placed on a table or other surface, such as the dashboard or console of a vehicle, they are vulnerable to sliding or being knocked off onto the floor or ground, which can lead to breakage or permanent damage.

Most handheld electronic devices have housings that are made of hard, smooth plastic or metal. The front faces of these housings usually include ornamental shapes and designs, but the rear faces are typically plain and smooth. Often, the rear, side, and bottom surfaces include switches, buttons, and access ports for receiving interchangeable components, batteries, and carrying cases.

These switches, buttons, and access ports leave exposed joints, seams, and grooves. Flip-type and swivel telephones also include integral plastic and metal hinges and swivels.

In addition, many of these handheld electronic devices are configured to fit on top of other components or into accessory components, such as caddies, cradles, chargers, docking stations, computer monitors, carrying cases, and clips. When coupled together, there is usually very little clearance between the device and the accessory component. As a result, it is not possible to place a thick, anti-slip material directly onto the device, as doing so would prevent or impede the device from properly mating with its accessory component.

In addition to adding anti-slip functionality to handheld electronic devices, there are many other applications in which anti-slip functionality is desired. For example, in the printing industry, it is desirable to have rollers and other paper handling components that have high gripping capacity and that are highly durable. There are countless other material handling examples across many other industries in which it is desirable to have durable, anti-slip functionality.

Also, many applications exist in the sport and recreation industries. For example, many sports require the use of gloves and handheld equipment, such as bats, rackets, paddles, sticks, and other devices with gripping surfaces. In these sports, it is usually desirable to have anti-slip functionality associated with this equipment. In addition to gloves and handheld equipment, there are many sporting and recreation applications in which it is desirable that there be anti-slip functionality between a user's clothing and his equipment.

Although there have been significant developments over the years in the area of producing thin elastomers, considerable shortcomings remain.

Description of the Preferred Embodiment

While the making and using of various embodiments of the present application are discussed in detail below, it will be appreciated that the present application provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of exemplary ways to make and use the application, and do not limit the scope of the application. It should be noted that the layers in the figures are not drawn to scale.

The present application is directed to a thin, soft, silicone-elastomer film for use as an anti-slip skin, or applique. The skin can be applied, adhered, sewn, or otherwise attached to sports equipment, sports clothing, objects, a person's skin, the clothing of a user, or placed between objects, all of which act to prevent or reduce undesired relative motion between adjacent objects.

According to the present application, a silicone elastomer is bonded to a thin, dimensionally stable plastic film substrate to form a flexible, thin film, referred to herein as a "silicone-elastomer film." It has been found that the use of a silicone material having a low-d urometer, i.e., less than 40 on the Shore A scale, and a dimensionally stable, smooth, plastic film having a surface energy of about 40

Dynes/cm, provides the best results. It will be appreciated that many thin plastic films are not dimensionally stable. This configuration overcomes many of the problems associated with thin elastomeric sheets. For example, with the silicone- elastomer film of the present application, the silicone elastomer is stabilized and prevented from "stretching" and sliding off the surface to which it is applied. In addition, an inexpensive acrylic pressure sensitive adhesive may be used to bond the silicone-elastomer film to other surfaces.

The silicone-elastomer film is durable, resilient, and capable of adhering to a suitable acrylic pressure sensitive adhesive. In the preferred embodiment of the present application, the silicone elastomer is applied to the plastic film. Then, a textured and polished surface finish is imparted to the silicone elastomer by a casting means having a polished surface finish. This process creates a textured and polished surface finish on the silicone elastomer. The phrase "surface finish" will be used herein to describe the surface of materials on a very fine, or microscopic, scale; whereas the phrase "surface texture" will be used to describe the surface of materials on a larger scale, i.e., to indicate the presence of raised bumps, dimples, or ridges that can be seen with the naked eye and felt by hand.

The production of a silicone elastomer with a polished and textured surface finish represents a significant discovery in the present application. It has been found that the use of such a silicone elastomer greatly improves the performance characteristics of the silicone-elastomer film. An equally important discovery in the present application is the production and use of the thin, dimensionally stable, smooth plastic film substrate. These discoveries provide significant benefits, including: (1) the casting means releases cleanly from the silicone elastomer after curing; (2) the silicone elastomer is significantly more "grippy," i.e., has a higher coefficient of friction with more anti-slip functionality; and (3) the silicone elastomer is resistant to collecting dust and debris.

The present application provides significant advantages, including: (1) stability of the elastomer as related to processing and use is provided; (2) a stabilized bonding surface for applying to other materials is provided; and (3) the ability to efficiently handle a very thin elastomeric coating having a very low durometer is provided.

Referring to FIGS. 1 through 3 in the drawings, the preferred embodiment of a silicone-elastomer film 11 is illustrated. As shown in FIG. 1 , film 11 is formed as a sheet, and may be formed as a continuous sheet on a roll (not shown). FIG. 2 is a side view of film 11 showing a two-layer construction of film 11 , in which a layer of silicone elastomer 13 having an exposed surface 19 with a polished surface finish is disposed on an upper surface 17 of a thin plastic film substrate 15. FIG. 3 is an enlarged view showing the pattern of the surface texture shown in FIGS. 1 and 2, with upraised bubble-shaped dimples 21 being separated by narrow valleys 23.

As explained above, the textured and polished surface finish of silicone- elastomer film 11 is preferably formed by a casting means, such as a casting film, having a polished surface finish. It will be appreciated that the surface finish of surface 19 of silicone elastomer 13 may also be formed by other means, such as tools, dies, or rollers; provided that such means imparts, imprints, or transfers, the desired textured and polished surface finish to silicone elastomer 13. Surface 19 is preferably formed to have a surface texture or pattern, as shown, although surface 19 may alternatively be matte or smooth. It has been found that, in some instances, the surface texture of surface 19 does not contribute significantly to the anti-slip functionality of film 11 ; however, certain surface textures do hide imperfections in film 11 and prevent dust and debris, which are easily seen on matte and smooth surfaces, from collecting on surface 19. This improves the look and feel of silicone- elastomer film 11.

Plastic film substrate 15 is a thin, flexible film, preferably a clear film about 0.002 inches thick, that forms and provides a flexible, durable, dimensionally stable substrate. It is preferred that plastic film 15 have a smooth surface finish, as may be attained with a co-extrusion process, and have a surface energy lower than about 40 Dynes/cm. This combination ensures a strong bond between plastic film 15 and silicone elastomer 13. This unique bond prevents silicone elastomer 13 from easily being detached from plastic film 15 during manufacture and use of film 11. For aesthetic purposes, plastic film 15 and/or silicone elastomer 13 may be tinted or may include embedded or printed graphical indicia. It is preferred that the combined thickness of silicone-elastomer film 11 be no greater than about 0.032 inches.

Silicone elastomer 13 is formed to have a low-durometer, i.e., less than 40 on the Shore A scale. This, along with the inherent bonding characteristics of silicone materials, facilitates bonding with plastic film 15. Silicone 13 may be applied to plastic film 15 by pouring, spraying, spreading, doping, or any other conventional application means suitable for applying a silicone material to solid sheets or films. However, as described below, the preferred method of applying silicone elastomer 13 to plastic film 15 is by controlled pouring in a continuous production process in which silicone elastomer 13 is sandwiched between plastic film 15 and a casting means having a textured and polished surface finish.

Referring now also to FIG. 4 in the drawings, an alternative embodiment of the film is illustrated. In this embodiment, a film 25 has an upper portion 26 that has the same construction as film 11 described above, in that a silicone elastomer 27 is applied onto an upper surface 29 of plastic film 31. As such, silicone elastomer 27 has an exposed surface 33 with a textured and polished surface finish. To provide a means of affixing film 25 to an object, a layer of adhesive 35 is applied to a lower surface 37 of plastic film 31 , and a release liner 39 is placed against surface 41 of adhesive 35 for preventing contamination or setting of adhesive 35 prior to installation of film 25. Plastic film 31 provides a suitable base for which to bond adhesive layer 35, as it has been found that it is difficult to obtain a durable bond directly between adhesives and cured silicone materials. Adhesive 35 may be applied as a tape by other appropriate means, such as in liquid form. Prior to use, release liner 39 is removed from adhesive 35, allowing film 25 to be adhered to a surface.

Referring now also to FIG. 5 in the drawings, a second alternative embodiment of the film is illustrated. In this embodiment, a film 43 has an upper portion 44 that has the same construction as film 11 described above, in that a silicone elastomer 45 is applied onto an upper surface 47 of a plastic film 49. As such, silicone elastomer 45 has an exposed surface 50 with a textured and polished surface finish. A label stock 51 , which may include graphical and/or textual indicia or other desired items, is adhered to a lower surface 53 of plastic film 49 by applying an adhesive layer 55 to an upper surface 54 of label stock 51. This allows any graphical indicia on label stock 51 to be visible through silicone elastomer 45 and plastic film 49. To allow for application of film 43 to a surface, a second adhesive layer 57 is applied to a lower surface 58 of label stock 51 , and a release liner 59 is applied onto a lower surface 61 of adhesive layer 57.

Referring now also to FIG. 6 in the drawings, the preferred method of manufacturing a silicone-elastomer film 91 is schematically illustrated. The first step in the process is to form or provide a casting means, such as a casting film 71 , that is adapted to transfer a textured and polished surface finish to the silicone elastomer.

Casting film 71 may be formed by a wide variety of conventional means for forming such films. The production of casting film 71 may be an integral part of the process of manufacturing silicone-elastomer film 11 , or casting film 71 may be produced in a separate process prior to use in an off-site facility and stored in sheets or rolls 65. This allows casting film 71 to endure the heat of the curing process described below without undergoing any undesirable changes in shape, dimensions, or composition. _

Casting film 71 is conveyed toward one or more nipping, or pinch, rollers 81 , 83. At the same time, a plastic film substrate 73, which is preferably stored in a roll 75, is also conveyed toward nipping rollers 81 , 83. Due to the thinness of plastic film 73, it is preferred that plastic film 73 be heat stabilized prior to use. This heat stabilization ensures that plastic film 73 can endure the heat cycle of the curing process without cockling or buckling. This prior heat stabilization of plastic film 73 is not typical of plastic films.

Before casting film 71 and plastic film 73 are drawn through nipping rollers 81 , 83, a volume of silicone elastomer 79 is disposed on the upper surface of plastic film 73, preferably in liquid form by a nozzle 77, or a similar device. Then, plastic substrate 73, casting film 71 , and silicone elastomer 79 are drawn between nipping rollers 81 , 83. This causes silicone elastomer 79 to spread evenly at a selected thickness over plastic film 73 and transfers the textured and polished surface finish of casting film 71 to the exposed surface of silicone elastomer 79. This nipping process forms a film assembly 85 that is then subjected to a curing process, which is indicated by area 87 in FIG. 6. Curing process 87 may include raised temperatures and pressures for varying durations of time. The specific temperatures, pressures, and cure times may vary depending upon the specific characteristics that are desired in the final film. It will be appreciated that other layers of materials, such as adhesives, label stocks, and release liners, may also be combined with film assembly 85, and that these other layers may be added before or after curing process 87.

Next, casting film 71 is removed from film assembly 85 and captured on roller

89, leaving a completed silicone-elastomer film 91 having a textured and polished surface finish according to the present application. Once manufactured in sheet form, silicone-elastomer film 91 may be configured for a wide variety of uses and applications, by cutting, shaping, and other post-processing steps.

In an alternative method of manufacture, casting film 71 is reused after it is removed from film assembly 85. This embodiment is represented by the phantom lines in FIG. 6. In this embodiment, a film return loop 99 is provided so that casting film 71 may be returned to a location in the process prior to passage through nipping rollers 81 , 83.

The production method shown in the figures and described above is only one example of a configuration for manufacturing the silicone-elastomer films 91 according to the present application. The feed paths of casting film 71 and plastic film 73 may be configured in a variety of ways to achieve the same results. For example, the positions of the feed paths of casting film 71 and plastic film 73 may be reversed, with silicone elastomer 79 being applied to casting film 71 , rather than plastic film 73, prior to nipping rollers 81 , 83. Another possible configuration has the feed paths of casting film 71 and plastic film 73 in generally vertical orientations.

Referring now also to FIGS. 7 through 9 in the drawings, some possible uses of the silicone-elastomer film will now be described with respect to the configuration of FIG. 4. Because silicone-elastomer film 25 is typically formed as a sheet, a user may cut or otherwise shape portions of the sheet to create desired shapes and sizes of film 25. The user then removes release liner 39 from adhesive 35, and applies each film 25 to a selected surface. Film 25 then acts as an anti-slip applique for preventing or reducing movement of the selected surface relative to an adjacent surface.

In FIG. 7, a handheld electronic device 101 , in this instance a mobile telephone, onto which silicone-elastomer films 103, 105 are adhesively affixed for use as anti-slip skins, is shown. Skin 103 is applied to an outer surface 107 of device 101 , and skin 105 is applied to outer surfaces 109, 111. The outer surface of each skin 103, 105 is preferably formed to have a bubble pattern texture and polished surface finish, as shown in FIG. 3 and described above. Skins 103, 105 provide anti-slip functionality when device 101 is placed against other objects or surfaces because the exposed silicone material of skins 103, 105 grips the adjacent surfaces.

In FIG. 8, a silicone-elastomer film 113 is shown applied to the striking surface

115 of a ping-pong paddle 117. Silicone-elastomer film 113 ensures a good lateral grip between paddle 117 and a ball (not shown) struck by the paddle, thereby enhancing the ability of the user to impart spin on the ball when striking the ball. It will be appreciated that the silicone-elastomer films may be used on a wide variety of sporting equipment and in a wide variety of recreational applications.

In FIG. 9, a silicone-elastomer film 119 is shown in another use. Film 119 has been configured into small shapes for application to a user's fingertips 121. This provides for high levels of grip between fingertips 121 and objects being manipulated by the user. For example, films 119 may be used to allow the user to more easily pull sheets of paper from a stack, or to count money. An advantage of using films 119 in this application is that fingertips 121 are not fully enclosed, as with thimble- type fingertip appliances. This allows the user's fingers to "breathe," and prevents the user from feeling discomfort from heat buildup around fingertips 121.

Referring now also to FIGS. 10A-11 B in the drawings, the preferred embodiment and several alternative embodiments of a firm-fitting glove having one or more silicone-elastomer films are illustrated. FIGS. 10A-10D illustrate firm-fitting gloves having full-length finger portions, and FIGS. 11A and 11 B illustrate firm-fitting gloves with only partial-length finger portions.

Referring now to FIGS. 17A, 17B, 18, and 19, several additional alternative embodiments of the anti-slip silicone-elastomer films of the present application are illustrated. These embodiments depict uses of the anti-slip silicone-elastomer films of the present application in various motorcycle sports. In certain motorcycle sports, such as motocross, motorcycle racing, and motorcycle jumping, it is often desirable for the rider to be able to let go of the handle bars and hold onto the motorcycle with his legs or feet. For example, when riders grip the handle bars for long periods of time, their hands and arms become fatigued. The anti-slip silicone-elastomer films of the present application may be placed on the riders clothes and gear or at various _ _

locations on the motorcycle to allow the rider to periodically grip the motorcycle with his legs and/or feet. This helps relieve the fatigue in the rider's hands and arms.

In FIG. 17A, a motorcycle 231 having a frame assembly 232, a gas tank

233, and handle bars 235 and 237 is illustrated. Motorcycle 231 includes one or more anti-slip silicone-elastomer films 239 attached to gas tank 233, and one or more anti-slip silicone-elastomer films 241 and 243 attached to handle bars 235 and 237, respectively. FIG. 17B is an enlarged view of handle bar 235, 237 showing attachment of silicone-elastomer films 241 , 243. The attachment of silicone-elastomer films 241 and 243 to handle bars 235 and 237 provide anti-slip gripping of handle bars 237 and 237 for the rider.

The anti-slip silicone-elastomer films of the present application may also be used with and utilized in garments of clothing to provide anti-slip functionality. These garments include one or more pieces of material cut and/or patterned into certain articles of clothing, such as pants, shirts, coats, hats, helmets, shoes, and boots. The garments are formed from base materials and have anti-slip silicone-elastomer films incorporating into them. The silicone-elastomer films may be releasably integral with the base materials, may be permanently attached to the base materials, such as by stitching, bonding, or gluing, or may be releasably attached to the base materials.

For example, in FIG. 18, a pair of motorcycle rider's pants 245 is illustrated.

Pants 245 include a waist portion 246, two leg portions 247, optional narrowed bottoms 249, and one or more anti-slip silicone-elastomer films 251 attached at various locations on pants 245. Silicone-elastomer films 251 allow the rider to grip gas tank or other components of the motorcycle with his legs or feet. Silicone- elastomer films 251 may have an adhesive backing (not shown); and may be either integral with pants 245, or may be in the form of separate components. In those embodiments in which silicone-elastomer films 251 are configured for quick and easy removal from pants 245, it will be appreciated that a one or more release liners or receiver materials may be attached to pants 245 to facilitate the removal and replacement of the silicone-elastomer films.

In FIG. 19, a motorcycle rider 257 wearing pants 245 is shown riding . _

motorcycle 231. In this embodiment, silicone-elastomer films 251 of pants 245 match up with silicone-elastomer films 239 on gas tank 233. However, it should be understood that it is not necessary that both the rider's pants and the motorcycle each include anti-slip silicone-elastomer films. Indeed, the silicone-elastomer films of the present application may be used only one of the pants or the motorcycle.

Also, in FIG 19, the rider is wearing a pair of gloves 259 and a pair of boots 261 , each having anti-slip silicone-elastomer films associated therewith.

In other applications, the anti-slip silicone-elastomer film according to the present application may be used as an applique for, or sewn into, uniforms, clothing, or gear.

It is apparent that the silicone-elastomer films according to the present application may be used in many different applications across a wide variety of industries, particularly when configured, cut, shaped, and formed for specific applications. For example, the present application may also be used as follows: (1) as an outer surface of a sleeve for a printer roller or other paper handling equipment;

(2) as a self adhesive "hand pad" for weight lifters; (3) as a grip for flashlights; (4) as pads for eyeglass nosepieces; (5) as strips to be applied to the bottom of tool trays to keep tools from sliding; (6) as "barefoot" footwear; and (7) as an anti-slip skin for medical devices.

In an alternative embodiment, the silicone-elastomer is disposed on both sides of the plastic film. This can be done, for example, by either coating both sides of the plastic film, or by adhering two silicone-elastomer films together back to back. This configuration allows for anti-slip functionality on both sides of the silicone- elastomer film, and allows the use of the present application in applications in which it is undesirable to adhere the silicone-elastomer film directly to an object.

It is apparent that an invention with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just those forms, but is amenable to various changes and modifications without departing from the spirit thereof.
