Technical Field

[0001] This utility model relates to the field of daily necessities and souvenirs, and in particular to a commemorative coin, a cup lid, and a water cup. Background Technology

[0002] Water cups are common items in people's daily lives. To enrich the appearance of water cups and enhance their aesthetic appeal, some water cups on the market are decorated with commemorative coins, medals, and other ornaments on the lid.

[0003] Most existing commemorative coins and medals are made entirely of metal, with designs created through processes such as molding, engraving, inlaying, or printing on the metal surface. These designs convey the information conveyed through the metal. When in use, attaching the commemorative coin to the cup lid gives the cup a more distinctive appearance.

[0004] However, the content on the surface of existing commemorative coins can only be a concrete and limited presentation, allowing users' senses to remain at the level of basic visual communication, while the richer and more detailed information behind the commemorative coin or medal cannot be understood and obtained in a timely manner. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a commemorative coin, a cup lid, and a water cup. The overall structure of the commemorative coin is improved by incorporating a chip layer. This chip layer is designed with NFC sensing functionality, allowing users to scan it with mobile phones or other digital products to learn about other information contained in the commemorative coin. This not only provides visual appeal to the commemorative coin but also offers users additional emotional value.

[0006] To achieve the above objectives, firstly, this utility model adopts the following technical solution: a commemorative coin, comprising a base and a display body.

[0007] The main body of the display consists of an upper protective layer, a chip layer, a wave-absorbing and anti-metal protective layer, and an adhesive layer connected in sequence. The adhesive layer is connected to the base.

[0008] The outer surface of the upper protective layer serves as an image display platform, while the chip layer contains an NFC tag.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This application involves embedding an NFC tag within commemorative coins (including medals) to digitize information related to the coin. This information can include richer and more intuitive content such as images, text, audio, and video. Users can upload, edit, modify, and share this content using relevant software. Other users can then use the NFC function of their mobile phones, tablets, or other digital products to bring the NFC tag close to the coin. Upon sensing the tag, they will be directed to a relevant link and can open, browse, read, or play the uploaded content. This allows for quick and intuitive access to more information and stories behind the commemorative coin.

[0011] When customizing a personal commemorative badge as a gift, you can use relevant software to edit the message with pictures, text, audio, and video to send your blessings to the recipient. This not only creates a physical item with commemorative value, but also adds more meaningful digital content, bringing users more surprises and value.

[0012] This application enriches traditional commemorative coins with digital content, making it easier for users to quickly access more relevant information. It allows traditional products to undergo low-cost digital upgrades to keep up with the times, and more of their content can be stored and used long-term through relevant backend servers and other equipment. This preserves the collection, appreciation, and commemorative value of traditional commemorative coins while providing users with more information and emotional value.

[0013] Furthermore, the upper protective layer is made of non-metallic material, and the thickness of the upper protective layer is ≤15mm.

[0014] Furthermore, the outer surface of the upper protective layer is provided with at least one layer of non-metallic decorative panel, and the sum of the thickness of the upper protective layer and each decorative panel layer is ≤15mm.

[0015] Furthermore, the base has a connecting plane that connects to the adhesive layer.

[0016] Furthermore, the base has a groove for connecting the display body, wherein the adhesive layer is connected to the bottom of the groove.

[0017] Furthermore, the base is also equipped with mounting hardware for connection.

[0018] Secondly, this application also provides a cup lid, including the aforementioned commemorative coin and a lid body, wherein the base is connected to the lid body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] To expand the scope of use of commemorative coins and to add additional functions to the cup lid, this application fixes the aforementioned commemorative coin to the lid body to form a new cup lid structure. This makes the cup lid more attractive and also enables it to have information scanning and reading functions. When using the cup lid, electronic devices can be used to scan the information of the commemorative coin, increasing the fun of using the cup lid.

[0021] Meanwhile, the lid body can be a conventional groove-shaped structure, with the open end of the groove-shaped structure connecting to the cup body below. The outer bottom of the groove-shaped structure is the outer top of the lid body. The outer top of the lid body can also adopt a flat structure or other irregular structure. Connecting the bottom of the base to the outer top of the lid body allows for the connection between the commemorative coin and the lid body, forming a new cup lid. Of course, depending on the size and quantity of the commemorative coins, the coins can be arranged around the circumference of the lid body and connected using adhesive, magnetic attraction, or other methods to create another type of cup lid structure.

[0022] Furthermore, the cover body has a receiving cavity, and the commemorative coin is located inside the receiving cavity and fixedly connected to the receiving cavity.

[0023] Furthermore, the cover body has a receiving cavity, and the opening end of the receiving cavity is provided with a detachable fastener, through which the commemorative coin is fixed in the receiving cavity.

[0024] Thirdly, this application also provides a water cup, including the aforementioned cup lid and cup body, wherein the lid body is connected to the cup body.

[0040] In the diagram: Commemorative coin 100, decorative panel layer 110, display body 120, upper protective layer 121, chip layer 122, wave-absorbing and anti-metal protective layer 123, adhesive layer 124, base 130, groove 131, cover body 200, fastener 210, hollow structure 211, protective plate 212, receiving cavity 220, cup body 300, mounting piece 132, additional chamber 221. Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] like Figure 1-9 As shown, a commemorative coin includes a base 130 and a display body 120. The display body 120 includes an upper protective layer 121, a chip layer 122, a wave-absorbing and anti-metal protective layer 123, and an adhesive layer 124 connected in sequence. The adhesive layer 124 is connected to the base 130. The outer surface of the upper protective layer 121 is an image display platform, and the chip layer 122 has an NFC tag.

[0043] Understandably, the commemorative coin 100 should at least have a metallic texture to conform to consumers' preconceived notions. Therefore, the base 130 of this application is actually a metal product and can be designed as a disc structure, coin structure, etc. As the supporting structure of the entire commemorative coin 100, the base 130 ensures that the commemorative coin 100 has a certain rigidity while also conforming to mainstream aesthetics and having a metallic texture.

[0044] Compared to the existing traditional one-piece commemorative coin 100, the structure of the display body 120 is customizable. Because the display body 120 has a multi-layered structure, the outer surface of the upper protective layer 121 serves as the image display platform for the entire commemorative coin 100. Images can be directly printed for display, or mica sheets, epoxy transparent layers (including planar and / or three-dimensional images), etc., can be pasted on for image display. Personalized designs can be made according to user needs, giving the commemorative coin 100 a direct visual experience. The chip layer 122 can be a single chip structure, i.e., a single circuit board structure (PCB board, FPC board); the chip layer 122 can also be a layer structure formed by multiple chip structures laid flat. Regardless of the structural form of the chip layer 122, it must at least have NFC functionality. Therefore, in this application, the chip layer 122 has an NFC tag. When the chip layer 122 is a single-layer chip structure, it is an FPC flexible circuit board with NFC functionality; when the chip layer 122 is a structure composed of multiple chip structures laid flat, at least one of the multiple chip structures is an NFC tag.

[0045] Due to the presence of the base 130, in order to avoid metal interference, a wave-absorbing and anti-metal protective layer 123 is provided below the chip layer 122, which is a wave-absorbing material to reduce metal interference. Common wave-absorbing materials include metal wave-absorbing materials, silicon carbide wave-absorbing materials, etc.

[0046] To facilitate the overall production and personalized customization of the commemorative coin 100, an adhesive layer 124 (such as 3M adhesive layer) is provided below the wave-absorbing and anti-metal protective layer 123. The adhesive layer 124 can be used to connect the display body 120 and the base 130, which facilitates the installation of the entire commemorative coin 100 and the individual production of each component.

[0047] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, both the display body 120 and the base 130 are circular plate-shaped structures. The display body 120, from top to bottom, consists of an upper protective layer 121, a chip layer 122, a wave-absorbing and anti-metal protective layer 123, and an adhesive layer 124. The base 130 is located below the adhesive layer 124. The upper protective layer 121 has a printed pattern, making it an image display platform. The adhesive layer 124 has a plastic protective film; after tearing off the plastic protective film, the adhesive layer 124 can be separated from one side of the base 130. Figure 3 (A) is located on the other side of the base 130. Figure 3 The coin (B) also features a design, giving the entire commemorative coin a double-layered design and NFC functionality.

[0048] In some embodiments, the upper protective layer 121 is made of a non-metallic material, and the thickness of the upper protective layer 121 is ≤15mm.

[0049] Understandably, to avoid interference with signal transmission, the upper protective layer 121 needs to be non-metallic. The upper protective layer 121 can be made of coated paper, PVC layer, etc. To avoid affecting signal transmission and to ensure that the sensing device (electronic component) can receive the signal, when designing the thickness of the upper protective layer 121, it is necessary to ensure that the thickness of the upper protective layer 121 is ≤15mm, preferably in the range of 1mm-10mm.

[0050] In some embodiments, the outer surface of the upper protective layer 121 is provided with at least one layer of non-metallic decorative panel layer 110, and the sum of the thicknesses of the upper protective layer 121 and each decorative panel layer 110 is ≤15mm.

[0051] The outer surface of the upper protective layer 121 can be directly printed with images to achieve the function of image display. However, due to the influence of the material of the upper protective layer 121, the operation of printing directly on the surface of the upper protective layer 121 for patterns with more prominent colors or more complex designs is less aesthetically pleasing. Therefore, in order to improve the overall aesthetics of the commemorative coin 100, a decorative panel layer 110 can also be covered on the outer surface of the upper protective layer 121.

[0052] The decorative panel layer 110 can be various layer structures such as pictures, mica sheets, and epoxy transparent layers. Pictures and mica sheets can change the overall shape of the commemorative coin 100 and enhance its appearance. The upper surface of the epoxy transparent layer is a spherical (arc-shaped) structure, similar to a convex lens, which can change the visual effect of the pattern printed on the upper protective layer 121 and make the overall appearance of the commemorative coin 100 richer.

[0053] The decorative panel layer 110 and the upper protective layer 121 can be fixed by means of adhesive, magnetic attraction, or drip sealing. During production, the decorative panel layer 110 can be customized according to requirements and then connected to the display body 120, so that the commemorative coin 100 can have a variety of shapes.

[0054] Furthermore, the decorative panel layer 110 can be multi-layered, such as covering the surface of the decorative panel layer 110 with another layer of epoxy resin, or designing various decorative panel layers 110 of different shapes. The decorative panel layers 110 can be stacked in sequence to form a three-dimensional graphic structure, so that the overall structure of the commemorative coin 100 is more visually impactful.

[0055] Meanwhile, in order to avoid the various structural layers above the chip layer 122 from affecting signal transmission, it is also necessary to ensure that the sum of the thicknesses of the upper protective layer 121 and each decorative panel layer 110 is ≤15mm, preferably in the range of 1mm-10mm.

[0056] like Figure 1 , 2 As shown, a decorative panel layer 110 is provided above the upper protective layer 121. The decorative panel layer 110 also adopts a circular plate structure to ensure that the decorative panel layer 110 and the upper protective layer 121 completely overlap, avoiding the feeling of foreign objects due to the overlapping of the layers. It is best to use adhesive backing to connect the decorative panel layer 110 and the upper protective layer 121 to facilitate the assembly of the two.

[0057] In some embodiments, the base 130 has a connecting plane that is connected to the adhesive layer 124.

[0058] The base 130 can have various structures, such as a plate-like structure, a block-like structure, or other irregular shapes. A common structure for the commemorative coin 100 is a disc shape. The structure of the base 130 can also be designed based on the structure of the display body 120, taking into account the circular, square, or other structures of the display body 120 to determine the overall shape of the base 130. However, based on the layered structure design of the display body 120, the base 130 of this application has at least a connecting plane to ensure a large contact area between the base 130 and the display body 120, thereby ensuring the stability of their connection.

[0059] like Figure 2 , 4 As shown, in one embodiment of this application, the base 130 is a circular plate structure with two flat sides, showing that the adhesive layer 124 of the display body 120 contacts and is fixedly connected to one side of the base 130.

[0060] In some embodiments, the base 130 has a groove 131 for connecting the display body 120, wherein the adhesive layer 124 is connected to the bottom of the groove 131.

[0061] To further enhance the aesthetics of the base 130 and display body 120 after connection, a groove 131 (circular, square, etc.) with the same shape as the display body 120 can be provided on the base 130. The bottom of the groove 131 forms a connection platform for the base 130, and the display body 120 is embedded within and fixed to the groove 131. Simultaneously, placing the display body 120 within the groove 131 reduces the likelihood of separation between the display body 120 and the base 130, increasing the connection stability between them.

[0062] like Figure 1As shown, in one embodiment of this application, the base 130 is a circular plate structure, and a circular groove 131 is provided on one side of the base 130. The display body 120 is a circular plate structure that fits into the groove 131. The display body 120 is embedded in the groove 131, and the adhesive layer 124 contacts and is fixedly connected to the bottom of the groove 131.

[0063] In some embodiments, the base 130 is also provided with a mounting member 132 for connection.

[0064] Understandably, besides being displayed, the commemorative coin 100 can also be worn, used as a refrigerator magnet, or connected to other items to fulfill its function. Therefore, this application includes a mounting piece 132 on the base 130. The mounting piece 132 can be positioned on the periphery, top, or bottom of the base 130, allowing for connection between the commemorative coin 100 and other materials. Specifically, when the mounting piece 132 is positioned on the periphery of the base 130, a connecting ring and connecting rope (either a chain or a strap) can be used. The connecting ring is fixed to the periphery of the base 130, and the connecting rope passes through the connecting ring. The ends of the connecting rope can be detachably or securely connected, allowing the entire commemorative coin 100 to be hung on a person (neck) or other items.

[0065] Given the conventional structure of the commemorative coin 100, its base 130 usually has two sides. One side of the base 130 is connected to the display body 120. In order to facilitate the display of the image on the display body 120, this application fixes the mounting piece 132 to the other side of the base 130. After the mounting piece 132 is connected to other items, the image on the display body 120 can be displayed more clearly.

[0066] Mounting component 132 can adopt a magnetic, snap-fit, or other structure. This application demonstrates several structures for mounting component 132, such as... Figure 10 As shown, the mounting piece 132 uses a pin structure, which allows the commemorative coin 100 to be attached to easily perforated items such as clothing. Figure 11 As shown, the mounting component 132 adopts a magnetic structure. The mounting component 132 can be divided into a female and male magnetic clasp, or it can use a single magnet. When the mounting component 132 is a single magnet, it is fixed to the bottom of the base 130. In this way, the commemorative coin 100 can be connected to items that can attract magnets, such as refrigerators. When the mounting component 132 has a female and male magnetic clasp, the female magnetic clasp is fixed to the base 130, and the male magnetic clasp is magnetically attracted to the female magnetic clasp. In this way, the commemorative coin 100 can be magnetically fixed to thinner items such as clothing. Figure 12As shown, the mounting part 132 can also use a butterfly buckle, which is fixed to the base 130. The butterfly buckle can facilitate the sewing of the commemorative coin 100 to clothing and other easily permeable items.

[0067] The commemorative coin 100 provided in this application, by setting a sensing chip (NFC tag) inside the commemorative coin 100 (including the medal), can digitally read the content information related to the commemorative coin 100. The content can be richer and more intuitive information such as pictures, texts, audio and video. Users can upload, edit, modify and share this picture, text and audio and video content through relevant software. Then, other users can use the NFC function of mobile phones, tablets or other digital products to approach the sensing chip. After sensing, they will be directed to the relevant link and can open, browse, read or play the uploaded picture, text or audio and video information. In this way, more information and related stories behind the commemorative coin 100 can be quickly and intuitively obtained.

[0068] When customizing a personal commemorative badge as a gift, you can use relevant software to edit the message with pictures, text, audio, and video to send your blessings to the recipient. This not only creates a physical item with commemorative value, but also adds more meaningful digital content, bringing users more surprises and value.

[0069] This application enriches the traditional commemorative coin 100 with digital content, making it easier for users to quickly access more relevant information. It allows traditional products to undergo low-cost digital upgrades to keep up with the times, and more of its content can be stored and used long-term through relevant backend servers and other equipment. This preserves the collection, appreciation, and commemorative value of the traditional commemorative coin 100, while also bringing users more information and emotional value.

[0070] Based on the structure of the commemorative coin 100 described above, this application also provides a cup lid, including the commemorative coin 100 and a lid body 200, wherein the base 130 is connected to the lid body 200.

[0071] To expand the scope of use of the commemorative coin 100 and to add additional functions to the cup lid, this application fixes the commemorative coin 100 onto the lid body 200 to form a new cup lid structure. This makes the cup lid more attractive and also enables it to have information scanning and reading functions. When using the cup lid, the information of the commemorative coin 100 can be scanned using electronic devices, increasing the fun of using the cup lid.

[0072] Meanwhile, the lid body 200 can be a conventional groove-shaped structure, with the open end of the groove-shaped structure connected to the cup body 300 below. The outer bottom of the groove-shaped structure is the outer top of the lid body 200. The outer top of the lid body 200 can adopt a flat structure or other irregular structure. Connecting the bottom of the base 130 to the outer top of the lid body 200 can connect the commemorative coin 100 and the lid body 200 to form a new cup lid. Of course, depending on the size and quantity of the commemorative coins 100, the coins 100 can be arranged around the circumference of the lid body 200 and connected by adhesive, magnetic attraction, or other methods to form a cup lid with another structure.

[0073] like Figure 5 As shown, in one embodiment of this application, the lid body 200 is a circular lid-shaped structure. The lower end of the lid body 200 is connected to the cup body 300, and the upper end of the lid body 200 is a flat structure. The bottom of the base 130 is overlapped and fixed with the flat surface of the lid body 200. The two can be fixed by adhesive, magnetic attraction, or other means, so that the cup lid has a better visual experience and also has NFC function.

[0074] In some embodiments, the cover body 200 has a receiving cavity 220, and the commemorative coin 100 is located inside the receiving cavity 220 and fixedly connected to the receiving cavity 220.

[0075] To facilitate the positioning and connection of the commemorative coin 100 on the cover body 200, a receiving cavity 220 can be opened on the cover body 200. The depth of the receiving cavity 220 can be deep or shallow. As long as the base 130 of the commemorative coin 100 is at least partially embedded in the receiving cavity 220, and the structure of the receiving cavity 220 is compatible with the overall shape of the commemorative coin 100, the commemorative coin 100 and the receiving cavity 220 can be positioned and connected by means of adhesive, magnetic attraction, etc.

[0076] like Figure 6 As shown, in one embodiment of this application, a receiving cavity 220 is provided on the top of the cover body 200. The receiving cavity 220 is a circular groove structure. The commemorative coin 100 is embedded in the receiving cavity 220, and the bottom of the base 130 is fixed to the bottom of the receiving cavity 220.

[0077] In some embodiments, the cover body 200 has a receiving cavity 220, and the opening end of the receiving cavity 220 is provided with a detachable fastener 210, and the commemorative coin 100 is fixed in the receiving cavity 220 by the fastener 210.

[0078] The commemorative coin 100 and the cover body 200 can be fixedly connected or detachably connected. To achieve a detachable connection between the commemorative coin 100 and the cover body 200, this application also provides a new connection method. Specifically, the receiving cavity 220 is opened on the outer top of the cover body 200, and the fixing member 210 is located at the opening of the receiving cavity 220. This indicates that the cooperation between the receiving cavity 220 and the fixing member 210 can form a chamber for placing the commemorative coin 100. Separating the fixing member 210 from the receiving cavity 220 allows for a detachable connection between the commemorative coin 100 and the cover body 200.

[0079] To enable the detachable connection between the fixing member 210 and the receiving cavity 220, the fixing member 210 can be a ring-shaped structure, a cap-shaped structure, etc. The fixing member 210 and the receiving cavity 220 are detachably connected using one or more methods such as threads, snaps, and magnetic attraction. This detachable connection between the fixing member 210 and the receiving cavity 220 allows for the detachable connection between the commemorative coin 100 placed inside the receiving cavity 220 and the lid body 200. This facilitates handling the commemorative coin 100 and also allows for the combined viewing of the lid body 200 and the commemorative coin 100, giving the entire lid a richer visual appeal.

[0080] Specifically, such as Figure 7 As shown, in one embodiment of this application, the fixing member 210 is a cover ring structure. The fixing member 210 and the upper end of the receiving cavity 220 are threaded together. The interior of the fixing member 210 is a circular hollow structure 211, and the size of the commemorative coin 100 is larger than the size of the hollow structure 211. After the fixing member 210 and the receiving cavity 220 are connected, the commemorative coin 100 and the cover body 200 can be connected. The presence of the hollow structure 211 makes it convenient for the user to observe the commemorative coin 100 and also convenient for the user to take out the commemorative coin 100 from the receiving cavity 220 for handling.

[0081] In another embodiment of this application, a fastener 210 structure is also provided, specifically, as follows: Figure 8 As shown, the difference between this structure and the structure described above is that a transparent protective plate 212 is provided below the fixing member 210. The size of the protective plate 212 is larger than the size of the hollow structure 211. When the fixing member 210 and the receiving cavity 220 are connected, the protective plate 212 is located between the receiving cavity 220 and the fixing member 210. With this structure, regardless of the size of the commemorative coin 100, the commemorative coin 100 can be smoothly fixed in the receiving cavity 220 through the fixing member 210 and the protective plate 212.

[0082] It is worth noting that when the mounting component 132 is provided below the base 130 of the commemorative coin 100, in order to make the connection between the commemorative coin 100 and the cover body 200 smoother, an additional cavity 221 for placing the mounting component 132 can be provided on the cover body 200. When the base 130 is directly fixed to the cover body 200, the additional cavity 221 is provided at the contact position between the cover body 200 and the base 130; when the cover body 200 is provided with a receiving cavity 220, such as Figure 13 As shown, the additional chamber 221 is formed at the bottom of the receiving chamber 220.

[0083] Based on the above-described lid structure, this application also provides a water cup, including the above-described lid and cup body 300, wherein the lid body 200 is connected to the cup body 300.

[0084] Understandably, the lid and body 300 can be fixedly connected as a single unit, requiring only a water inlet on either the lid body 200 or the body 300 to ensure the entire cup has a water storage function. Alternatively, the lid and body 300 can be detachably connected using a combination of threads, snaps, magnetic closures, or other methods to ensure they form a complete cup for convenient use. Figure 9 As shown in the illustration, this application demonstrates that the cup lid and cup body 300 are connected by a threaded connection, enabling a detachable connection between the cup lid and cup body 300. The overall structure of the cup lid can be... Figure 5 , 6 Any of the structures shown in 7 and 8.

[0085] The cup body 300 can be a conventional structure with only a liquid storage chamber. The side wall of the cup body 300 can be a single-layer structure or a double-layered insulation layer structure. In this case, the liquid stored in the liquid storage chamber can only achieve self-insulation (for a short period of time or within a certain time range) through its own temperature.
