If "first," "second," etc., are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0023] Please refer to Figures 1 to 3 or Figures 4 to 6 As shown, this embodiment of the present invention provides a coffee filter cup, including a cup holder 100 and a cup body 20; the cup holder 100 is adapted to be placed above a coffee cup; the cup body 20 includes a cup body 210, which is in the shape of an inverted frustum and placed above the cup holder 100. The cup body 210 has an upward-opening placement cavity 211 and a liquid outlet hole 212 located at the bottom of the cup body 210. The placement cavity 211 is connected to the coffee cup through the liquid outlet hole 212; the outer wall of the cup body 210 is provided with at least one printing plane 213, which extends from the opening of the cup body 210 to the bottom. The printing plane 213 is adapted to print patterns or text; the cup holder 100 is at least partially projected onto the printing plane 213 in a direction perpendicular to the printing plane 213.

[0024] According to the coffee filter cup of this utility model embodiment, when printing patterns or text, the cup body 20 is separated from the cup base 100, and the printing plane 213 on the cup body 210 is horizontally placed below the printing equipment (such as an engraving machine, laser machine, ultraviolet printer, etc.) to print patterns or text; when in use, the cup body 20, the cup base 100 and the coffee cup are stacked in sequence, the coffee filter paper is placed in the placement cavity 211 of the cup body 210, coffee powder and water are placed in the coffee filter paper, and the coffee liquid extracted by the coffee filter paper flows from the liquid outlet 212 into the coffee cup.

[0025] It should be noted that in traditional coffee filter cups, because the cup body 20 is fixedly connected to the cup base 100, the visual area on the side of the cup body 20 (especially the lower middle part) is difficult to utilize effectively during production and post-processing. If you want to print patterns or text on the side of the cup body 20, the integrated cup base 100 will severely hinder the movement and operation of the printing equipment, resulting in a limited printing area, incomplete patterns or text, and low production efficiency. This greatly limits the potential of filter cups as everyday consumer products in terms of appearance customization and brand promotion; alternatively, if the cup body 20 is curved, the curvature will cause variations in the depth of the printed patterns or text, affecting the printing effect.

[0026] According to the coffee filter cup of this utility model embodiment, by setting the printing plane 213, it is easier to print patterns or text than the curved surface of a traditional coffee cup; and by separating the cup body 20 and the cup base 100, the cup base 100 is avoided from affecting the movement of the printing device, and the printing area on the side of the cup body 20 (especially the side near the cup base 100) can be fully utilized.

[0027] In this embodiment, brand logos, personalized decorations, and blessings can be printed on the printing plane 213; the printing process can be screen printing, transfer printing, or digital inkjet printing.

[0028] In some embodiments, combined with Figures 1 to 3 or Figures 4 to 6 As shown, the outer wall of the cup body 210 includes multiple printing planes 213. The multiple printing planes 213 surround the liquid outlet hole 212 to form the outer wall of the cup body 210. The cross-section of the outer wall of the cup body 210 is a regular polygon.

[0029] In this embodiment, compared to a single printing plane 213 or curved surface, each face of the regular polygon is a standard, continuous, pure plane. This allows for perfect printing with zero distortion and no variations in depth across the entire cup body 210 within a 360-degree range. The printing equipment can always maintain the optimal working distance and perpendicular angle to the printing surface, ensuring that the pattern or text is clear, uniform, and accurate on each face. Furthermore, the regular polygon structure facilitates precise positioning and fixation on the production line. Whether using manual clamps or automated turntables, the edges of the polygon can be easily gripped, ensuring that each printing plane 213 is aligned with the equipment's reference position. Moreover, multiple printing planes 213 provide multiple independent printing areas for the design, allowing brands to design a series of patterns or text (such as zodiac series or solar term series), providing users with dynamic and explorable visual interaction. Rotating the filter cup reveals different patterns or text, greatly enhancing the product's fun and artistic value.

[0030] In some embodiments, combined with Figure 1 or Figure 4As shown, the outer wall of the cup body 210 includes twelve printed planes 213, and the cross-section of the outer wall of the cup body 210 is a regular dodecagon.

[0031] In this embodiment, the regular dodecagon has a sufficient number of sides, making it very close to a circle in macroscopic vision, avoiding the obvious sharp edges that occur when the number of sides is small (such as hexagons and octagons), thus improving the user's grip and visual experience; and the twelve printed planes 213 are adapted to content with collective concepts such as zodiac signs and constellations, greatly enhancing the product's fun and artistic value.

[0032] In some embodiments, combined with Figures 1 to 3 or Figures 4 to 6 As shown, the inner wall of the cup body 210 is provided with a number of raised ribs 214, and the extending direction of the raised ribs 214 is parallel to the generatrix of the cup body 210.

[0033] In this embodiment, during the pour-over coffee process, a large amount of carbon dioxide (gas) is released when water comes into contact with coffee grounds. If this gas cannot be expelled smoothly, it will accumulate between the coffee filter paper and the inner wall of the cup body 210, forming an "airlock" that hinders the normal passage of water through the coffee grounds layer, resulting in over-extraction in some areas and under-extraction in others. The raised ribs 214 provide a vertical venting channel from the bottom to the top of the coffee bed, allowing the gas to be expelled smoothly and quickly upwards, ensuring uniform contact between hot water and coffee grounds.

[0034] In this embodiment, when the cross-section of the cup body 210 is a regular polygon, the protruding rib 214 can be set at the bending position of the cup body 210. The protruding rib 214 is used to fill the depression at the bending position of the cup body 210, improve the support effect on the coffee filter paper, and avoid excessive local stretching of the coffee filter paper.

[0035] In some embodiments, combined with Figures 1 to 3 or Figures 4 to 6 As shown, the cup body 20 also includes a connecting post 220, which surrounds the liquid outlet 212 and is located below the bottom of the cup body 210; the cup seat 100 is provided with a insertion hole 110, which is suitable for insertion and engagement with the connecting post 220. The connection post 220 and the insertion hole 110 cooperate to prevent the cup body 20 from tilting during use.

[0036] In some embodiments, combined with Figure 3 or Figure 6 As shown, the cup body 20 also includes a guide ring 240. The guide ring 240 is located at one end of the connecting post 220 near the cup seat 100. The guide ring 240 is coaxial with the connecting post 220 and surrounds the liquid outlet hole 212. The lower end face of the guide ring 240 is lower than the lower end face of the liquid outlet hole 212.

[0037] In this embodiment, the guide ring 240 enters the insertion hole 110 before the connecting post 220, which is used to preposition the cup body 20 and the cup seat 100, making it convenient for the user to assemble; and when the cup body 20 is placed independently on the table, the guide ring 240 effectively prevents the lower end face of the liquid outlet 212 from contacting the table, avoiding external impurities from contaminating the liquid outlet 212.

[0038] In some embodiments, combined with Figure 3 or Figure 6 As shown, the outer periphery of the connecting column 220 is provided with a rotation positioning part 230; the seat is provided with a positioning groove 120 that cooperates with the rotation positioning part 230 to restrict the rotation of the cup body 20 relative to the cup seat 100. This ensures a stable connection between the cup body 20 and the cup seat 100.

[0039] In some embodiments, combined with Figures 1 to 3 or Figures 4 to 6 As shown, the rotating positioning part 230 is coaxially arranged with the connecting column 220, and the outer periphery of the cross-section is a regular polygon; the positioning groove 120 is coaxially arranged with the insertion hole 110, and is located at the end of the insertion hole 110 facing the cup body 20.

[0040] In this embodiment, the outer periphery of the rotating positioning part 230 is a regular polygon that matches the cup body 210, thereby optimizing the visual appearance of the product.

[0041] In other embodiments, the rotation positioning part 230 may also be in the form of a positioning post disposed on one side of the connecting post 220. The rotation of the cup body 20 is restricted by the cooperation between the connecting post 220 and the insertion hole 110, and by the cooperation between the positioning post and the cup holder 100.

[0042] In some embodiments, combined with Figure 3 or Figure 6 As shown, a partial surface of the bottom of the positioning groove 120 is sunken to form a ventilation groove 130. A partial surface of the bottom of the ventilation groove 130 has an ultrasonic ring protrusion 140, which points from the cup seat 100 to the cup body 20. The ultrasonic ring protrusion 140 is higher than the bottom of the positioning groove 120.

[0043] In this embodiment, the ultrasonic ring protrusion 140 in the ventilation groove 130 supports the cup body 20. The ventilation groove 130 effectively prevents the cup body 20 from being tightly attached to the bottom of the positioning groove 120, thus avoiding difficulty in separating the cup body 20 from the cup seat 100 due to atmospheric pressure.

[0044] Furthermore, when it is necessary to produce a product that integrates the cup body 20 and the cup holder 100, that is, after the pattern or text on the cup body 20 is printed, it is necessary to connect the cup body 20 and the cup holder 100 in an inseparable manner. Ultrasonic welding process can be used to transmit sound waves to the welding part (such as the ultrasonic ring protrusion 140 in this embodiment) by using high-frequency oscillation. This allows the ultrasonic ring protrusion 140 to reach the melting point and connect the cup body 20 and the cup holder 100. In addition, the ventilation groove 130 can well accommodate the melted ultrasonic ring protrusion 140, ensuring that the connection between the cup body 20 and the cup holder 100 of each coffee filter cup is stable while the overall external dimensions are basically consistent.

[0045] In some embodiments, combined with Figures 1 to 3 or Figures 4 to 6 As shown, the cup body 20 includes a first cup body 21 ( Figure 1 (as shown) and the second cup body 22 ( Figure 4 As shown). The angle between the generatrix of the cup body 210 of the first cup body 21 and its bottom surface (as shown). Figure 3 The included angle α) ranges from 65 degrees to 75 degrees, suitable for cake-shaped coffee filters; the angle between the generatrix of the cup body 210 of the second cup body 22 and its bottom surface ( Figure 6 The included angle (β) ranges from 55 to 65 degrees and is suitable for funnel-shaped coffee filters.

[0046] In this embodiment, by replacing the first cup body 21 or the second cup body 22 to adapt to different types of coffee filter paper, and reusing the cup holder 100, the adaptability of the coffee filter cup to different coffee filter paper is improved, while the total number of parts of the coffee filter cup is reduced, thus reducing manufacturing costs.

[0047] In other embodiments, the angle between the generatrix of the cup body 210 of the first cup body 21 and its bottom surface or the angle between the generatrix of the cup body 210 of the second cup body 22 and its bottom surface can be adjusted based on the actual angle of the cake-shaped coffee filter paper or the funnel-shaped coffee filter paper.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
