Abstract
Description
- This U.S. patent application claims priority to U.S. patent application Ser. No. 29/528,173, filed May 27, 2015, entitled “Wearable Ring,” where this application is incorporated by reference as if fully set forth herein.
- Certain aspects of the disclosure relate to a method of manufacturing a silicone ring. In particular, the disclosure relates to the manufacture of a ring composed of three components that form a thin-line segment around the entire circumference of the ring.
- Wedding rings or wedding bands have customarily been worn by both men and women throughout history. The ring is normally worn on the base of the left or right “ring” finger. One possible reason the “ring” or fourth finger on the left hand is the chosen location for wearing a ring is that the likelihood of injury is minimized. Humans are predominately right handed and wearing a wedding ring on the left hand on the fourth finger likely results in a decreased amount of injuries and less wear and tear on the ring itself. Typically, wedding rings are made of precious metals such as gold, silver, palladium, and platinum. Other examples include those rings made out of titanium, tungsten, ceramic, etc. Certain occupations and active lifestyles are not conducive to the wearing of a wedding band. Serious injury can result to the finger and hand if a conventional wedding ring gets caught on an object. Many individuals remove their rings for safekeeping, only to find that after completing work or other activity the ring has been misplaced, lost, or even stolen. The current disclosure describes a silicone ring and the process of making the silicone ring as a viable replacement to conventional wedding bands.
- To alleviate the hazards and risks associated with the wearing of a conventional wedding band, a ring manufactured by silicone compression-molding virtually eliminates all potential risks of injury to the hand and finger. The silicone ring also provides a cost effective alternative to those who desire to wear a wedding ring continuously and a ring that will not interfere with an active lifestyle. Silicone rubber is widely known to be resistant to extreme temperatures, is resistant to abrasions, is resistant to chemicals, is resistant to weather, is hypoallergenic, is comfortable to wear, and is less harmful to the environment than many organic rubbers.
- Conventional methods of compression molding can produce various flaws in the component characteristics such as color loss and discoloration, surface texture blisters and waviness, and optical distortion. Conventional compression molding methods are incapable of producing a thin-line ring of the current disclosure. The particular method of manufacturing developed in the current disclosure eliminates many of the common problems found in conventional methods of making compression-molded products. The compression molding process described herein achieves a symmetrical inner-band that runs through the entire circumference of the ring. The disclosed compression molding methods include critical steps, specific temperatures, pressures, compression times, material requirements, etc. to achieve a symmetrical inner-band. Without the disclosed process, the edges of the two outer-band halves and the edges of the inner band that could not be controlled or defined by other known methods.
- This Summary provides an introduction to some general concepts relating to this disclosure in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the disclosure.
- Certain aspects of the present disclosure relate to a unique compression-molded silicon ring, or methods of making such rings. In accordance with one exemplary aspect of the disclosure, an outer-band or a first outer-band half or half of a ring hoop is formed through compression molding. A matching second outer-band half or half of a ring hoop is then formed by compression molding. The outer-band half is placed in a second mold and a spacer-insert mold is placed over the second mold. The spacer-insert mold contains a cavity for each ring template that is filled with a silicone rubber, silicone dough, or silicone shot. A second outer-band half of the ring is placed a fourth mold. The fourth mold is placed over the spacer-insert mold. All three-conjoined molds are inserted into a compression chamber. The two outer-band halves are compression molded into a single ring with an inner, thin-line band formed by the spacer-insert mold that was filled with silicone rubber.
- In another exemplary embodiment of the disclosure, a thin-line silicone ring is described. The silicone ring consists of two outer-band halves that are joined to form a single band. The two outer-band halves are separated by a silicone inner band. The silicone inner band is symmetrical throughout the entire circumference of the outer band and is positioned equidistantly in between the two outer-band halves. The inner silicone-band can typically be composed of a grade of material that is the same or different than the outer band, and typically a different color.

FIG. 7 shows an exemplary embodiment of a compression-molded silicone ring prior to the removal of the excess silicone after the outer-band halves and inner silicone-band have been vulcanized together. - In the following description of various examples of a compression-molded silicone ring and methods of manufacture in this disclosure, reference is made to the accompanying drawings, which form a part hereof.
- It is to be understood that other compression-molded silicone rings and methods of manufacture may be utilized and that structural and functional modifications may be made from the specifically described examples and methods without departing from the scope of the present disclosure. Moreover, the figures of this disclosure may represent the scale and/or dimensions according to one or more embodiments, and as such contribute to the teaching of such dimensional scaling. However, those skilled in the art will readily appreciate that the disclosure herein is not limited to the scales, dimensions, proportions, and/or orientations shown in the figures.
- The embodiments and methods described herein provide, inter alia, a compression-molded silicone ring and the method of manufacturing. The compression-molded silicone ring is unique and may be used as a substitute to a conventional wedding band. The compression-molded silicone ring provides a safe alternative to individuals with active lifestyles or professions not conducive to the wearing of conventional rings or wedding bands due to the risk of injury to the finger and hand.
- The design of the compression-molded silicone ring and associated process of manufacturing result in a ring design that includes a nearly symmetrical inner band or “thin line” that runs through the circumference of the ring. Two outer bands “sandwich” the inner band and results in a visually appealing ring. In one embodiment, the inner band has a different color and/or made from a different grade of silicone rubber than the outer bands. In yet another embodiment, the outer bands are multi-colored and/or made from different grades of silicone rubber.
- In certain examples, such as the examples of
FIGS. 1, 2, and 3 , the compression-moldedsilicone ring 10 comprises the compression-molded silicone ring includes at least two outer-band halves 14. The first outer-band half 14 and second outer-band half 14 are separated by a silicone inner-band 15. Theouter surface 11 of the silicone ring is formed by the outer surfaces of two outer-band halves 14 and the outer surface of the inner-band 15. The inner portions of outer-band halves 14 and inner-band 15 also form theinner surface 12 of the silicone ring. Thesilicone ring 10 also includes aflat edge 13 that is part of the outside structure of outer-band 14. - In certain examples, the
inner band 15 is positioned between outer-band halves 14, in the exact center of the ring, such that the width of the first outer-band half 14, as seen inFIG. 2 , is the same width as the second outer-band half 14. In other examples, as seen inFIG. 2 , the width of inner-band 15 is less than the width of outer-band half 14. In yet other examples, the width of inner-band 15 is greater than the width of outer-band halves 14. In still other examples, the inner-band 15 has the same width of outer-band halves 14. In each example, the uniform inner-band 15 follows or runs the entire circumference of the silicone ring outer-bands 14. - In some examples, the inner-
band 15 is a different color than the outer-band halves 14. In other examples, a first outer-band half has a different color than the inner-band half 15, and a different color than the second outer-band half 14. In this embodiment, the silicone ring is composed of three different colors. - Silicone rubber is an elastomer composed of silicone, carbon, hydrogen, and oxygen. Silicone rubbers have a vast amount of uses across various industries and have inherently stable properties. Silicone rubber is non-reactive and are virtually unaffected by weather, can withstand temperatures from roughly −50° Celsius to +250° Celsius. Silicone rubber tends to maintain its flexibility and resilience, is inert with no taste or smell, and can range from transparent to brightly colored. Due to these advantageous properties, silicone rubber has applications in the automotive industry, apparel, medical devices, electronics, the food industry, etc. Various grades of silicone rubber are commercially available such as Medical grade, Food Quality/FDA compliant grades, High-Temperature Vulcanizing (HTV) grade, Room Temperature Vulcanization (RTV) grade, Liquid Silicone Rubber (LSR), 2-Part Silicone Rubber (RTV-2), Silicone Rubber (RTV-1), and silicone gels. HTV is further divided into millable type silicone rubber and liquid type silicone rubber based upon the degree of polymerization. Millable type silicone rubber is generally composed of polyorgarnosilioxan and silica that forms a base compound. The base compound is catalyzed, pigmented, and cured and is readily available as a commercial product. This type of silicone rubber is also known as High Consistency Silicone Rubber (HCR). In certain examples, the outer-
band half 14 is composed of a food grade silicone rubber. In other examples, the inner-band 15 is composed of a food-grade silicone rubber. In still other examples, the outer-band halves 14 and the inner-band 15 can be made of any combination of silicone rubbers described above, or silicone rubbers not described or developed yet. - Some aspects of the disclosure relate to a method of manufacturing a silicone ring via compression-molding process. The method takes advantage of the properties of silicone rubber that include fast-curing and low compression set times. Solid silicone rubber is vulcanized in molds by heat and pressure.
FIG. 4 shows the main steps of the method of manufacturing the compression-molded silicone ring. In one example, food-grade HCR strips are loaded into afirst mold 400 that will form the outer-band halves by compression molding instep 404. This is repeated twice as shown bystep 408 to produce two outer-band halves that form the compression-molded silicone ring. In one example, the outer-band halves formed by steps 400-408 are made from the same grade of silicone rubber. In another example, a different grade of silicone rubber is used when the second set of outer-band halves are formed instep 408. In certain examples, the color of the outer-band halves are the same. In other examples, the outer-band halves used to form thesilicone ring 10 are different colors. Using a different grade of silicone rubber for the two outer-band halves provides further options to alter the texture and/or appearance of the ring. - The outer-band halves are then removed from the first mold and inserted into a second mold as described in
step 412. Step 416 requires that a spacer-insert mold, which helps form the inner-band, be placed over the second mold. Instep 420 the spacer-insert mold cavities are loaded with silicone rubber, silicone material, or a silicone dough. The remaining outer-band halves are loaded into a fourth mold instep 424. Step 428 requires that the fourth mold be placed over the spacer-insert mold and the second mold, and then the stack of three molds is inserted into a compression chamber instep 432. Instep 436, the outer-band halves and the inner-band silicone rubber are vulcanized together and then cooled instep 440. The finished silicone ring is removed from the molds instep 444 and any excess silicone material or flash is trimmed from the final product. - Each cavity in the compression molds are individually filled with a precisely weighed amount of silicone rubber or preloaded with strips or pieces of silicone rubber. The compression presses, generally, are hydraulically operated and heated with steam or electrically. Temperature of the mold during the vulcanization process plays a critical role in properly forming the silicone ring. High temperatures are required to minimize the vulcanization time, but temperatures that are too high can result in the “scorching” of the silicone rubber. The vulcanization time is determined by the temperature of the selected silicone material, size or thickness of the component being produced, and the temperature of the molds.
- In certain examples, various ring sizes are produced by the methods of the current disclosure and require a variable amount of silicone rubber to produce the outer-band half. The desired thickness of the outer-band half will also determine the amount of silicone rubber required. In one example, 1.00-1.25 grams of silicone rubber are used to form the outer-band half. In other examples, 0.75-1.50 grams of silicone rubber are used to form the outer-band half. In yet another example, 0.50-1.75 grams of silicone rubber are used to form the outer-band half. In still another example, 0.25-3.25 grams of silicone rubber are used to form the outer-band half.
- Different amounts of silicone rubber are required due to the various ring sizes that are produced by the methods of the current disclosure. The desired thickness of the outer-band halves will also determine the amount of silicone rubber required in the current method. Additionally, different amounts of silicone rubber are required to produce the inner-band, depending upon the ring size as well as the desired thickness of the inner band. In one example, 2-2.5 grams of silicone rubber are used to fill the spacer-insert mold cavities. In other examples, 1.75-2.75 grams of silicone rubber are used to fill the spacer-insert mold cavities. In yet another example, 1.5-3.0 grams of silicone rubber are used to fill the spacer-insert mold cavities. In still another example, 1.0-4.0 grams of silicone rubber are used to fill the spacer-insert mold cavities.
- Non-uniform heating and temperatures that are too high commonly lead to blistered compression-molded products, an overly thick flash, dull and clouded color, warped structures, undefined borders, and bleeding colors. Molds that are too cold can also result in blistered components or dull finishes. In certain examples, in an effort to eliminate flaws due to inadequate process temperatures, the compression molds are heated to 200° Celsius in the vulcanization process. In other examples, the molds are heated from 190° Celsius to 210° Celsius. In yet another example, the molds are heated from 185° Celsius to 215° Celsius. In one example, the molds are heated from 175° Celsius to 225° Celsius.
- Insufficient compression time or mold cycles can result in blistering, uncured silicone, and warping. To prevent flaws in the components as a result of incorrect compression times or mold cycles, in one example, the mold compression time is 3 minutes. In other examples, the mold compression time is between 2.5 and 3.5 minutes. In yet another example, the mold compression time is between 2.0 and 4.0 minutes. In still another example, the mold compression time is between 0.5 and 5.0 minutes.
- Blistering, surface clouding, color segregation, and weak components can result from improper compression pressures. To eliminate problems associated with improper compression pressures, in one example, the mold compression pressure to form the outer-band half is 200 kg/cm2. In other examples, the mold compression pressure to form the outer-band half is between 175 kg/cm2 and 225 kg/cm2. In yet another example, the mold compression pressure to form the outer-band half is between 150 kg/cm2 and 250 kg/cm2. In still another example, the mold compression pressure to form the outer-band half is between 125 kg/cm2 and 275 kg/cm2. In one example, the mold compression pressure to form the outer-band half is between 100 kg/cm2 and 300 kg/cm2.
- As discussed above, to eliminate problems associated with improper compression pressures, the mold compression pressure to form the inner-band in one example is 120 kg/cm2. In other examples, the mold compression pressure to form the inner-band is between 110 kg/cm2 and 130 kg/cm2. In yet another example, the mold compression pressure to form the inner-band is between 100 kg/cm2 and 150 kg/cm2. In still another example, the mold compression pressure to form the inner-band is between 50 kg/cm2 and 200 kg/cm2.
- In some exemplary embodiments, such as the exemplary embodiment of
FIG. 5A , afirst compression mold 50 of the method of manufacturing is depicted. Thecompression mold 50 includes abase plate 51 andtop plate press 52. In one example, silicone strips are loaded into thefirst compression mold 50 that will form a first set of outer-band halves by compression molding. Silicone rubber orsilicone material 53 is loaded on thebase plate 51 of thefirst compression mold 50. A first set of outer-band halves are formed by compressing thetop plate press 52 with thebase plate 51. After vulcanization, the first set of outer-band halves 14 are removed from thefirst compression mold 50. This step is repeated to produce a second set of outer-band halves that will later be used with the first set of outer-band halves to form the compression-molded silicone rings.FIG. 5B shows the outer-band halves removed from theexcess silicone material 53, 54, and 55. When an outer-band half 14 is removed from theexcess silicone material 53, 54, and 55 a void 56 remains in the remainingexcess silicone material 53.Excess silicone material 53, 54, and 55 is discarded or recycled. - As shown in
FIG. 6A , after removal from thefirst compression mold 50, the outer-band halves 14 are inserted into a secondcompression mold plate 60. In particular, as shown inFIG. 6A , the outer-band halves 14 are loaded in mold cavities 61 in the secondcompression mold plate 60. The next step requires that a third compression mold plate, also referred to as a spacer-insert mold plate 65 be placed over the secondcompression mold plate 60.FIG. 6B depicts spacer-insert mold plate 65 on top of the secondcompression mold plate 60. As shown inFIG. 6B , silicone rubber, silicone material, or asilicone dough 66, which will form the inner-band of the silicone ring, is then loaded ontocavity platforms 62. Also shown inFIG. 6B are the outer-band halves 14 resident in the secondcompression mold plate 60. The remaining outer-band halves 14 are loaded into a fourthcompression mold plate 70.FIG. 6C depicts the fourthcompression mold plate 70 loaded with outer-band halves 14. Thefourth mold plate 70 is then placed over the spacer-insert mold plate 65 and the secondcompression mold plate 60. The stack of three mold plates is then inserted into a compression chamber at a predetermined heat, pressure, and for a specific length of time. The outer-band halves and the inner-band silicone rubber are vulcanized together and then cooled. The finished silicone ring is removed from the molds and any excess silicone material or flash is trimmed from the final product. The final product is the compression-moldedsilicone ring 10 as depicted inFIG. 7 . Thesilicone ring 10 is removed from themold leaving void 72 in theexcess silicone 71. The excess silicone orflash 71 is trimmed from ring. The finished product includes the two outer-band halves 14 with a center thin-line inner-band 15. - The current disclosure describes a unique method of manufacturing a distinctly multi-colored product from compression-molding of silicone rubber. By using various molds outlined in the example above, a silicone ring with a colored inner band is manufactured. Conventional compression molding techniques cannot be used to create a multicolored silicone ring or other object with distinct and defined colors within the completed product. In conventional methods, when different-colored or pigmented silicone rubbers are compressed together, a blurred or “tie dye” type color pattern emerges as a result of the heat and compression. In one example of the current disclosure, the method of manufacturing a compression-molded silicone ring produces a multi-colored ring with a distinct separation of colors.
- The unique compression-molded silicon rings, or methods of making such rings include rings sized in accordance with United States size specifications based upon the ring inner circumference.
- These process descriptions are merely exemplary. In certain embodiments, the process may include additional combinations or substitutions of some or all of the steps described above. Moreover, additional and alternative suitable variations, forms and components for the process will be recognized by those skilled in the art given the benefit of this disclosure.
