The components in the drawings are not necessarily to scale, with emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. Similarly, references numbers followed by an alphabetic letter represent different examples of the corresponding part.
The drawings illustrate only example embodiments and are therefore not to be considered limiting of the scope described herein, as other equally effective embodiments are within the scope and spirit of this disclosure. The elements and features shown in the drawings are not necessarily drawn to scale, emphasis instead being placed upon clearly illustrating the principles of the embodiments. Additionally, certain dimensions may be exaggerated to help visually convey certain principles. In the drawings, similar reference numerals between figures designate like or corresponding, but not necessarily the same, elements.
In the following paragraphs, the embodiments are described in further detail by way of example with reference to the attached drawings. In the description, well known components, methods, and/or processing techniques are omitted or briefly described so as not to obscure the embodiments.
Casino currencies can be made of a metallic central core overmolded by a successive injection shot of different colors, formulations, and carrying different security additives. In casinos and especially on table games, the chips can be handled in stacks of chips. When in a stack, the casino personnel and the patrons can see only the edge of the chips. In order to clearly differentiate the chips while in a stack including the denomination, which can also be called sets, the chips can carry multiple inserts or colored patterns. Those differentiation elements can be brought by design during the injection molding process. Typically, those inserts of patterns will carry security additives, such as an ultra violet (UV) or infrared (IR) security additive that will glow under a special light exposure. The security additive can be used to authenticate a stack or rack of chips.
A clip insert can be added between successive injections during the injection mold process. The clip insert can be attached to an affixing point on a base component of the chip prior to injection of one or more overmolded components. An overmolded component can be injected over the clip insert and the base component. This injection can prevent the clip inserts from being removed from the chip 100. During the overmolding process, the plastic can flow inside the clip insert and fill an aperture and a gap between the clip insert and the base component. The aperture can represent an intricate design, and the material from the overmolding process can fill the aperture to create an intricate effect.
Turning now to the drawings, exemplary embodiments are described in detail. With reference to
In one embodiment of manufacturing the gaming chip 100, the component 103 can be injected into an injection mold. In some embodiments, the core 109 can be part of the component 103, such that the component 103 and core 109 is injection molded in one step. In other embodiments, the core can be made of a denser material, such as, for example, metal. The core 109 can include an RFID tag. When proximate to an RFID antenna, the RFID antenna can read data from the RFID tag. The component 103 can be injection molded around the core 109 with the core 109 being surrounded by the component 103.
The clip inserts 106 can be shaped in a similar manner to an edge of the chip 100. The clip inserts 106 can be clipped on to the component 103. The component 112 can be overmolded onto the component 103, the clip inserts 106, and the core 109. The component 112 can include more than one successive overmolded injections. Each of the successive overmolded injections can correspond to a different color or formulation, include different security additives, or have other differences. The component 112 can be made from transparent, semi-transparent, or opaque materials. The security additives can include material that glows under a special light like ultraviolet light or infrared light. In some embodiments, a stack or rack of chips 100 can be authenticated by exposing the stack or rack to the special light.
The clip insert 106 can include one or more apertures 115. The apertures 115 can be in a variety of patterns or shapes. The aperture 115 can be a window with a second material enclosed within the window. The clip insert 106 can have a recessed lip along the inside of the window. The second material can similarly have a recessed edge that fits within the lip along the edge of the window of the clip insert 106. As a non-limiting example, a gold piece can be placed within the window as the second material.
The apertures 115 can be filled with material from the component 112. The overmolded component 112 can be visible through the apertures 115. As an example, the component 112 can fill the apertures 115 such that an edge surface of the clip insert 106 is flush with the component 112 within the apertures 115. The component 112 can prevent the clip inserts 106 from being removed. The clip inserts 106 can be manufactured with very fine patterns to accommodate customer requirements including any kind of letters, wording, logos, images, and other patterns.
The clip inserts 106 can be made from a variety of materials, such as, for example, synthetic, mineral, metal, gold, silver, titanium, jade, stone, mother of pearl, crystal, wood, gemstone, or other materials. The clip inserts 106 can include one or more holograms. The clip inserts 106 can be from injection molding, machining, etching, lamination, shaped with a press, or another manufacturing technique.
The materials used to make a clip insert 106 can have different densities. Because the weight of a chip 100 needs to fit within an acceptable range, using dense materials throughout a chip 100 can add excess weight. Because of the smaller size of the clip insert 106 relative to the chip 100, a denser material can be used in the clip insert 106 without substantially effecting the overall weight of the chip 100. Security pigments can be very expensive. Based on the size of the clip inserts 106 relative to the chip 100, expensive security pigments can be used more efficiently on the edge of the chip 100 by using security pigments in the clip insert 106.
The clip inserts 106 can be attached to a first shot of an injection that creates a main body of the chip 100, such as a component 103. The clip insert 106 can also be attached to any subsequent shot as long as the parts can then be overmolded to fully lock the clip insert 106 in place to prevent anyone from pulling the clip inserts 106 apart from the component 103. In some embodiments, a single clip insert 106 can be used. In other embodiments, more than one clip insert 106 can be used, for example, three, five, six, eight, or another quantity of clip inserts 106 can be used.
The clip inserts 106 can have a different color, formulation, design, or other property than the component 103 and component 112. The clip inserts 106 can also include multiple colors or other differentiating elements. As an example, a first clip insert 106 can have a UV pigment visible at 365 nm, while another clip insert 106 can have a UV pigment visible at 254 nm, and other clip inserts 106 can have an IR pigments that glow at different respective colors. By varying the materials in different clip inserts 106, an exponential number of chip configurations can be used, which can increase overall security in the chips 100. In addition, an order of different security features, such as IR and UV pigments, in different clip inserts 106 can be used to enhance security.
In the above example, the clip inserts 106 can be ordered with a UV 365 nm pigment, then a UV 254 nm pigment, then an IR visible green pigment, where a chip 100 with the IR visible green pigment clip insert 106 positioned between the UV 365 nm and 254 nm clip inserts 106 would fail a security check. A variety of security pigments can be used to create varying patterns or images on the clip inserts 106 using one or more security pigment on each clip insert 106.
In some embodiments, the clip insert 106 can be visible only from an edge of the gaming chip 100. The clip insert 106 can be one part of an annular design element visible from the side of the chip 100. The clip inserts 106 can be decorated with other printing techniques or with in mold decoration (IMD) or in mold labeling (IML). The clip inserts 106 can include a cavity or indentation along the edge to create a shaped chip 100 or a shaped edge of the chip 100.
The clip inserts 106 can be marked to carry a visible or invisible code, such as, for example, a QR code or other coding solution. The clip inserts 106 can be marked by printing, laser engraving, or another method of marking. A casino security system can validate the code or validate other security elements discussed herein. The clip inserts 106 can be made from transparent, semi-transparent, or opaque materials. The clip inserts 106 can have different textures or have a different material hardness. In some embodiments, the change in texture or hardness of the material in contrast to component 103 or 112 can be undetectable by a human finger, which can add additional security to the chip 100.
In some embodiments, the clip insert 106 can include an RFID transponder. The RFID transponder can be coupled to a currency product, one or more LEDs, or other electronic circuitry or device. The RFID transponder can generate electricity to the electronic circuitry or device in response to a special event, interrogation, or being within an RFID field.
With reference to
The component 103 can be made from multiple injections of a material. In one example, the component 103 can be made from a first injection followed by one or more additional molds being injected onto the first injection. Each of the injections can correspond to a different color, formulation, include different security additives, or have other differences. The component 103 can be made from transparent, semi-transparent, or opaque materials. The security additives can include material that glows under a special light like ultraviolet light or infrared light. In some embodiments, a stack or rack of chips 100a can be authenticated by exposing the stack or rack to the special light.
The tabs 203/206 can be protrusions from the component 103 separated by a predefined distance, and the clip insert 106 can fit snug on the protrusions 203/206. In some embodiments, a distance between an outer edge of tab 203 and an outer edge of tab 206 can be greater at a point furthest from the chip 100 than at a point contacting the component 103. The greater distance at the furthest point can facilitate a tighter fit with the clip insert 106.
The surface 209 and the surface 212 can be of different lengths to ensure the clip insert 106 is inserted in a desired direction as will be shown later in more detail. The corner 215 and the corner 218 can be acute angles. The acute angles can help hold the clip insert 106 in place. The component 103 can include other crevices, such as crevices shown around the core 109. These crevices maximize the ability for an overmolded layer to bond, such as component 112 (
With reference to
A proximal side of the protrusion 303 can mate against the surface 209 of the component 203. Similarly, a proximal side of the protrusion 306 can mate against the surface 212 of the component 203. A corner of the protrusion 303 can mate with the corner 215, while a corner of the protrusion 306 can mate with the corner 215. In some embodiments, the angle of the corner of the protrusions 303/306 can be the same as the angle of the corner 215 and 218. In another embodiment, the angle of the corner of the protrusions 303/306 can be less than the angle of the corner 215 and 218.
The lengths of the protrusions 303/306 can prevent improper clip insert 106 installation. As an example, the protrusion 303 can be shorter than the protrusion 306 (or vice versa), and therefore prevent the clip insert 106 from being installed upside-down. When upside-down, the longer protrusion 306 cannot fit along the shorter surface 209. Because of this mistake-proof feature, an assembler cannot install the clip inserts 106 incorrectly on the component 103. In some embodiments, the protrusion 303 and 306 can be shorter than surface 209 and 212 respectively to allow for easier insertion of the clip insert 106 during manufacturing.
When mounting each clip insert 106, the clip insert can be pressed onto each affixing point of the component 103. In some embodiments, the clip insert 106 can be held on based on the fit of the corner of protrusion 303/306 into the acute corner 215/218. When in place, the angle of less than 90 degrees for corner 215/218 can prevent the clip insert from being pulled away from the component 103 unless a force is applied. In some embodiments, the protrusion 303 can fit snuggly against the protrusion 203 and the protrusion 306 can fit snugly against the protrusion 206. As an example, a force can be required to position the protrusions 303/306 of the clip insert 106 around the outsides of protrusions 203 and 206. In yet another embodiment, the clip insert 106 can fit loosely onto the affixing point of the component 103 until the overmolding process takes place.
A cavity 309 can be formed between the component 103 and the clip insert 106a for each clip insert 106a. The cavity 309 can be surrounded on two side by the protrusions 203/206, by an edge of the component 103 on another side, and by the clip insert 106a on three sides. The one or more apertures 115 can pass through to the cavities 309.
When the one or more clip inserts 106 are in place, a material from the component 112 can be overmolded onto the chip 100. The material from the component 112 can fill the cavity 309. The material can harden to prevent the clip insert 106 from moving with respect to the component 103. The material from the component 112 can also occupy the space within the apertures 115 of the clip inserts 106.
With reference to
A cavity bound by walls 406, 409, 412, and a top wall (not visible) can correspond to the cavity 309. In one embodiment, the walls 406, 409, 412, or the top wall can include one or more crevices, such as indents, cavities, or apertures that can be filled with material from the component 112 during the overmolding process. The material within the crevice can better adhere the clip insert 106 to the component 112. The protrusions 303 and 306 can be of different lengths to prevent backward installation.
With reference to
After the overmolding process, material from the component 112 can cover the surfaces 418 and 421. The surface 415 can remain uncovered by the component 112. An edge of the chip 100 can include the surface 415, component 112 within the apertures 115 of clip insert 106, component 112 over the tabs 418 and 421, component 103, and other surfaces.
With reference to
A cavity bound by walls 406, 409, 412, and a top wall (not visible) can correspond to the cavity 309. In one embodiment, the walls 406, 409, 412, or the top wall can include one or more crevices, such as indents, cavities, or apertures that can be filled with material from the component 112 during the overmolding process. The material within the crevice can better adhere the clip insert 106a to the component 112. The protrusions 303 and 306 can be of different lengths to prevent backward installation.
The clip insert 106a can be made from more than one material. According to one example, one or more injections forms a clip insert 106 including the apertures 115. The one or more injections are performed with one or more materials including a first material proximate to the apertures 115. Then a subsequent one or more injections fills the apertures 115 with a different material (in contrast to the first material) to form the clip insert 106a.
The different material can match a color of the first material surrounding the aperture 115 such that the clip insert 106a looks to the human eye as if there was never an aperture 115 after the subsequent injections are performed. The different material can be formed by adding one or more IR and/or UV pigment to the first material. As an example, a 365 nm pigment can be added to the material that fills a first aperture 115 and a UV 254 nm pigment can be added to the material that fills a second aperture. When a 365 nm light is applied to the chip 100, the first aperture becomes visible. Similarly, when a 254 nm light is applied to the chip 100, the second aperture becomes visible.
The amount of expensive security pigments needed to create additional security features can be minimized because the apertures 115 can be made small relative to the size of the chip 100. Further, intricate designs or lettering can be made invisible to the human eye while visible to security personal using a special light. In some embodiments, information about the chip 100 can be embedded in the chip using the apertures 115. For example, the characters “$10” can be applied as an aperture 115 to be filled by the subsequent injection. When a special light (e.g., 254 nm light) is shown over the chip 100, the “$10” can be seen to confirm the chip 100 is of the denomination for ten dollars. As such, if a patron altered a ten dollar denomination chip 100 to make it look like a one hundred dollar denomination chip, the “$10” would still show when the special light is shown, and thus the security personal could easily detect the fraudulent chip.

In some embodiments, the clip insert 106b can include multiple windows 509 of various shapes. The multiple windows 509 can be filled by a single piece of a second material or a subset of windows 509 can each be filled by a different piece of the second material. In one example, different materials are used for each of the subset of windows 509. Each window 509 can be the shape of a rectangle, a circle, an oval, a square, a star, a character such as a letter or number, or some other shape.

At box 1103, the process 1100 can include injecting a first injection. The first injection can refer to a single injection or multiple injections. For example, one or more injections can be used to create the component 103. The mold can include one or more protrusions for use in affix a clip insert 106 to the component 103.
At box 1106, the process 1100 can include creating a clip insert. For example, a clip inserts 106 can be made from a variety of materials, such as, for example, synthetic, mineral, metal, gold, silver, titanium, jade, stone, mother of pearl, crystal, wood, gemstone, or other materials. The clip inserts 106 can include one or more holograms. The clip inserts 106 can be from injection molding, machining, etching, lamination, shaped with a press, or another manufacturing technique.
The materials used to make a clip insert 106 can have different densities. Because the weight of a chip 100 needs to fit within an acceptable range, using dense materials throughout a chip 100 can add excess weight. Because of the smaller size of the clip insert 106 relative to the chip 100, a denser material can be used in the clip insert 106 without substantially effecting the overall weight of the chip 100. Security pigments can be very expensive. Based on the size of the clip inserts 106 relative to the chip 100, expensive security pigments more efficiently be used on the edge of the chip 100 by using security pigments in the clip insert 106.
At box 1109, the process 1100 can include positioning the clip insert on the first injection. A machine or person can position the clip insert 106 against component 103. The machine or person can attach the clip insert 106 onto the component 103. In one embodiment, the clip insert 106 can be pressed with a pressure against an affixing point to secure the clip insert 106 onto the component 103. The clip insert 106 can have one or more protrusions that engage one or more protrusions on the component 103. As an example, an inside edge of the protrusions 303 and 306 can engage with an outside edge of protrusions 203 and 206.
At box 1112, the process 1100 can include injecting a second injections. For example, the component 112 can be overmolded onto the component 103 and the clip insert 106. The second injection can include one or more injections. The second injection can prevent the clip inserts 106 from moving with respect to the component 103. During the overmolding process, the plastic can flow inside the clip insert and fill an aperture and a gap between the clip insert and the base component.
