Abstract
Description
Technical Field
[0001] This application relates to the technical field of liquid containers, and in particular to a cup. Background Technology
[0002] Existing cups, such as water cups and portable coffee cups, are typically designed with a double-walled structure, consisting of an inner and outer shell, for purposes such as heat preservation, food preservation, or protecting the patterns on the outer wall. Since both cups have open openings, these openings need to be fused together to form the cup's rim. However, current technology usually involves nesting and connecting the two openings, but due to a certain height difference between the two cups, a noticeable step or gap exists at the connection point. When drinking, the user's lips directly contact this uneven connection, affecting the taste of the water. Utility Model Content
[0003] Therefore, it is necessary to provide a cup that can improve the user experience.
[0004] A cup includes an outer cup body and an inner cup body, at least a portion of the inner cup body being located inside the outer cup body. The inner cup body has a cavity and a rim communicating with the cavity. The outer periphery of the inner cup body near the rim is provided with a ring extending downward toward the inner cup body, and there is a gap between the ring and the outer peripheral wall of the inner cup body. The top of the outer cup body is located within the gap.
[0005] In one embodiment, the portion of the outer cup body located inside the ring is defined as the first portion, and the first portion is interference-fitted with the gap;
[0006] And / or, the ring is integrally formed into the inner cup body.
[0007] In one embodiment, the bottom of the ring has a flared portion, and the bottom end of the flared portion has an inlet for the first part to enter the gap; the outer periphery of the first part has an outwardly extending annular flange, and the flared portion abuts against the annular flange.
[0008] In one embodiment, a limiting structure for restricting the outer cup body from rotating along its own axis is further provided between the inner cup body and the outer cup body.
[0009] In one embodiment, the limiting structure includes a protrusion and a receiving groove that interlock with each other. The protrusion is formed on the outer peripheral wall of the inner cup body. The receiving groove is provided in the first part, and at least two receiving grooves are provided. The at least two receiving grooves are arranged sequentially at intervals along the circumference of the first part.
[0010] In one embodiment, the receiving groove extends downward from the top edge of the first portion, and the top edge of the first portion is provided with a notch for the protrusion to enter the receiving groove.
[0011] In one embodiment, the bottom of the outer cup and the bottom of the inner cup are connected by fasteners.
[0012] In one embodiment, the outer cup body includes a sidewall and a base, the top of the sidewall being connected to the ring sleeve, and the bottom of the sidewall being connected to the base;
[0013] The inner cup body has a connector on its bottom surface facing the outer cup body, and the fastener connects the connector and the base.
[0014] In one embodiment, the base has a first sealing element on the side away from the inner cup body to cover the connection between the fastener and the base;
[0015] And / or, a second seal is provided between the sidewall and the base;
[0016] And / or, a third seal is provided between the sidewall and the ring sleeve.
[0017] In one embodiment, the inner cup is a titanium cup and the outer cup is a transparent cup.
[0018] Compared with existing technologies, the cup provided in this application includes an outer cup body and an inner cup body. By setting a downward-extending ring on the outer periphery of the inner cup body's rim, and housing the top of the outer cup body between the ring and the inner cup body, a nested structure is formed, achieving a smooth and seamless connection between the inner and outer cup bodies at the rim. Therefore, when a user drinks water from this cup, their lips come into contact with a complete, continuous, and smooth transition surface formed by the rim of the inner cup body, rather than the uneven connection between the inner and outer cup bodies. This results in a smoother and more comfortable drinking experience, eliminating any uncomfortable foreign body sensation and improving the user's drinking experience and comfort.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0038] Please see Figures 1 to 7 This application provides a cup 1, including an outer cup body 10 and an inner cup body 20. At least a portion of the inner cup body 20 is located inside the outer cup body 10. The inner cup body 20 has a cavity 201 and a cup opening 202 communicating with the cavity 201. The outer periphery of the inner cup body 20 near the cup opening 202 is provided with a ring 21 extending downward toward the inner cup body 20, and there is a gap 203 between the ring 21 and the outer periphery of the inner cup body 20. The top of the outer cup body 10 is located within the gap 203.
[0039] It is understood that this embodiment provides a downwardly extending ring 21 on the outer periphery of the cup opening 202 of the inner cup body 20, and accommodates the top of the outer cup body 10 between the ring 21 and the inner cup body 20, forming a nested structure. This achieves a smooth and seamless connection between the inner cup body 20 and the outer cup body 10 at the cup opening 202. Therefore, when the user drinks water, their lips come into contact with a complete, continuous, and smooth transition surface formed by the cup opening 202 of the inner cup body 20, without contacting the uneven connection between the inner cup body 20 and the outer cup body 10. This results in a smooth and comfortable drinking experience, without any uncomfortable foreign body sensation, thus improving the user's drinking experience and comfort.
[0040] It is also understandable that the nested structure formed by the ring 21 and the top of the outer cup 10 improves the hygiene and ease of cleaning of the cup 1. Specifically, existing double-cup cups 1 have obvious steps or gaps at the connection between the two cups, which easily trap dirt and grime and are clear dead corners. Because this embodiment achieves a smooth transition between the inner cup 20 and the outer cup 10 at the cup opening 202, it avoids liquid and dirt from accumulating at the connection between the inner cup 20 and the outer cup 10, making cleaning simpler, effectively improving the hygiene standard of the cup 1, and reducing the risk of bacterial growth due to incomplete cleaning.
[0041] In one embodiment, the ring 21 is integrally formed into the inner cup body 20, making the connection between the ring 21 and the inner cup body 20 smoother and more seamless. This not only improves the user's experience when drinking from the cup 1, but also effectively prevents liquid from seeping from the connection between the ring 21 and the inner cup body 20 into the space between the inner cup body 20 and the outer cup body 10, thus improving the sealing performance between the inner cup body 20 and the outer cup body 10. Furthermore, the integral forming also increases the connection strength between the ring 21 and the inner cup body 20.
[0042] In one embodiment, see Figure 3 and Figure 4 The portion of the outer cup 10 located within the ring 21 is defined as the first portion 101, which is interference-fitted with the gap 203. That is, the two sides of the first portion 101 abut against the inner circumferential wall of the ring 21 and the outer circumferential wall of the inner cup 20, respectively. This makes the connection between the outer cup 10, the inner cup 20, and the ring 21 more stable, preventing the outer cup 10 from shifting vertically relative to the inner cup 20 or rotating along its own axis, thus improving the user experience.
[0043] In one embodiment, see Figure 3 and Figure 4The bottom of the ring 21 has a flared portion 210, and the bottom end of the flared portion 210 has an inlet for the first part 101 to enter the gap 203. It can be understood that the inner diameter of the flared portion 210 is larger than the inner diameter of the ring 21, so that the first part 101 of the outer cup 10 can be easily inserted between the ring 21 and the inner cup 20 from the inlet.
[0044] Further, see Figure 2 , Figure 3 and Figure 4 The outer periphery of the first part 101 is provided with an outwardly extending annular flange 11, and the flared part 210 abuts against the annular flange 11. In this way, the connection stability between the outer cup body 10 and the inner cup body 20 and the ring sleeve 21 can be further enhanced.
[0045] In one embodiment, a limiting structure is further provided between the inner cup body 20 and the outer cup body 10 to restrict the outer cup body 10 from rotating along its own axis. It is understood that the limiting structure can prevent either the inner cup body 20 or the outer cup body 10 from rotating relative to the other along its own axis, thereby not only improving the user experience when using the cup 1, but also ensuring that the relative positions of the inner cup body 20 and the outer cup body 10 do not change when workers assemble them, making installation more convenient.
[0046] For further details, please refer to [link / reference]. Figure 2 and Figure 4 The limiting structure includes a protrusion 22 extending outward from the outer peripheral wall of the inner cup 20, and the protrusion 22 is located at a position corresponding to the ring 21. Therefore, when the two sides of the first part 101 abut against the inner peripheral wall of the ring 21 and the outer peripheral wall of the inner cup 20 respectively, the protrusion 22 will naturally also abut against the first part 101 of the outer cup 10. It can be understood that the protrusion 22 increases the normal pressure on the contact surface between the inner cup 20 and the outer cup 10, thereby generating a strong static friction force to prevent either the inner cup 20 or the outer cup 10 from rotating relative to the other along its own axial direction.
[0047] For further details, please refer to [link / reference]. Figure 2 and Figure 4 The limiting structure also includes a receiving groove 102 that interlocks with the protrusion 22. The receiving groove 102 is provided in the first part 101, and at least two receiving grooves 102 are provided, which are arranged sequentially at intervals along the circumference of the first part 101. It can be understood that the two sides of the protrusion 22 arranged opposite to each other along the circumference of the inner cup 20 abut against the groove wall of the receiving groove 102, so that the protrusion 22 cannot move along the circumference of the inner cup 20 within the receiving groove 102, thereby preventing relative rotation between the inner cup 20 and the outer cup 10.
[0048] Indicative, in such Figure 2 In the illustrated embodiment, there are four receiving grooves 102 and four protrusions 22, all arranged sequentially at intervals along the circumference of the inner cup 20. In other embodiments, the number of receiving grooves 102 and protrusions 22 may also be different, and this application does not limit this, as long as the limiting structure can prevent relative rotation between the inner cup 20 and the outer cup 10. It can also be understood that when the number of receiving grooves 102 and protrusions 22 is one, relative rotation between the inner cup 20 and the outer cup 10 can be limited as long as the receiving groove 102 is not an annular groove extending along the axial direction of the outer cup 10.
[0049] Furthermore, the receiving groove 102 extends downward from the top edge of the first part 101, and the top edge of the first part 101 is provided with a notch for the protrusion 22 to enter the receiving groove 102. It is understood that when assembling the inner cup body 20 and the outer cup body 10 into a complete cup 1, the inner cup body 20 needs to be inserted into the outer cup body 10 along its own height direction (or the outer cup body 10 needs to be fitted over the inner cup body 20 along its own height direction). During the insertion process, the protrusion 22 can be simultaneously inserted into the receiving groove 102. In this way, not only can the inner cup body 20 and the outer cup body 10 be limited in position, but the precise alignment of the inner cup body 20 and the outer cup body 10 during assembly is also ensured.
[0050] In one embodiment, see Figure 3 and Figure 5 The bottom of the outer cup body 10 and the bottom of the inner cup body 20 are connected by fasteners 30. This prevents the outer cup body 10 and the inner cup body 20 from moving along their own height, making the connection between them more secure and less likely to separate. This avoids abnormal wear and structural damage caused by loose or wobbly parts, thus extending the service life of the cup 1.
[0051] In one embodiment, see Figure 3 and Figure 5 The outer cup body 10 includes a side wall 12 and a base 13. The top of the side wall 12 is connected to the ring 21, and the bottom of the side wall 12 is connected to the base 13; that is, the first part 101 is the top of the side wall 12. The inner cup body 20 has a connector 23 on its bottom surface facing the outer cup body 10, and a fastener 30 connects the connector 23 and the base 13. In this way, there is no need to provide a mounting hole on the inner cup body 20 for the connector 23 to pass through, which improves the integrity of the inner cup body 20 and can prevent liquid in the inner cup body 20 from leaking from the connection with the fastener 30.
[0052] It is understood that in this embodiment, the cup 1 is assembled as follows: first, the outer cup body 10 and the inner cup body 20 are fitted together, and then the connecting piece 23 and the base 13 are connected by fasteners 30, thereby assembling the inner cup body 20 and the outer cup body 10 into a complete cup 1. Indicatively, the fastener 30 is a screw, and the fastener 30, the base 13, and the connecting piece 23 are connected by threads. This reduces the cost of the cup 1 and simplifies its manufacturing process.
[0053] It is also understandable that the bottom of the side wall 12 is connected to the base 13, so that the shape and color of the base 13 can be changed according to the appearance requirements of the cup 1, thereby improving the appearance flexibility of the cup 1. Schematic, the side wall 12 and the base 13 are threadedly connected, thus facilitating the replacement of the base 13.
[0054] In one embodiment, see Figure 5 A first sealing element 41 is provided on the side of the base 13 away from the inner cup body 20 to cover the connection between the fastener 30 and the base 13. Thus, by hiding the fastener 30 between the base 13 and the first sealing element 41, the cup 1 is not only more aesthetically pleasing, but also avoids problems such as wear and rust on the fastener 30. When the first sealing element 41 is made of an elastic material, such as silicone or rubber, it also allows the cup 1 to operate silently when placed on a table, thereby improving the user experience.
[0055] In one embodiment, see Figure 5 A second seal 42 is provided between the side wall 12 and the base 13. This prevents liquids such as water from entering between the inner cup 20 and the outer cup 10 from the connection between the side wall 12 and the base 13.
[0056] In one embodiment, see Figure 4 A third seal 43 is provided between the side wall 12 and the ring 21. This prevents liquids such as water from entering between the inner cup 20 and the outer cup 10 from the connection between the side wall 12 and the ring 21.
[0057] In one embodiment, the inner cup body 20 is made of titanium. Titanium, as a biocompatible metal, is not prone to bacterial growth on its surface, is non-toxic and harmless to the human body, and does not cause any allergic reactions. Furthermore, titanium has extremely high chemical stability and is highly corrosion-resistant. Even when acidic beverages (such as juice or carbonated drinks) are stored for extended periods, heavy metal ions such as chromium and nickel will not leach out. Thus, the titanium cup body is not only healthier but also helps maintain the original flavor of the beverage. In addition, the titanium cup body is relatively lightweight. This embodiment reduces the overall weight of the cup 1 by reducing the weight of the inner cup body 20, making the cup 1 more portable and improving the user experience.
[0058] Furthermore, the outer cup body 10 is transparent. It is understandable that titanium cup bodies are relatively expensive; by choosing other materials to make the outer cup body 10, the overall cost of the cup 1 can be reduced, thereby lowering the selling price of the cup 1 and increasing its market share. In addition, when there are patterns on the outer periphery of the inner cup body 20 or between the inner cup body 20 and the outer cup body 10, a transparent cup body makes it easier to display those patterns.
[0059] As an illustration, the outer cup body 10 may be made of copolyester or other transparent materials, and this application does not impose any restrictions on this.
[0060] In one embodiment, see Figure 6 and Figure 7 The cup 1 also includes a cup lid 50 mounted on the ring 21 to seal the cup opening 202, which not only prevents foreign substances from entering the cup 1, but also prevents the liquid inside the cup 1 from leaking, thus making the cup 1 suitable for carrying.
[0061] Furthermore, a spout 51 is rotatably connected to the cup lid 50, and the spout 51 has a channel communicating with the cavity 201. The spout 51 is also arranged to rotate back and forth between the storage position and the drinking position, and when the spout 51 is in the storage position, the spout 51 is housed in the storage slot 501 of the cup lid 50, that is, the cup 1 is in the closed state at this time, as can be seen in the reference. Figure 6 When the spout 51 is in the drinking position, the end of the spout 51 away from the connection point with the lid 50 is outside the storage groove 501 of the lid 50. This means the cup 1 is in a drinkable state. (See reference...) Figure 7 In this way, one can drink water directly through the spout 51 after unscrewing the cup lid 50.
[0062] For further details, please refer to [link / reference]. Figure 7 A cover plate 52 is rotatably connected to the spout 51. When the cover plate 52 rotates relative to the cup lid 50, it can drive the spout 51 to rotate between the storage position and the drinking position. When the spout 51 is in the storage position, the cover plate 52 closes on the storage groove 501, so that the liquid in the cup 1 leaks from the spout 51.
[0063] In one embodiment, see Figure 6 and Figure 7 A handle 60 is rotatably connected to the lid 50, and there is a handle space between the handle 60 and the top surface of the lid 50 for a hand to pass through. Understandably, the user can move and carry the cup 1 through the handle 60, thus making the cup 1 more portable.
[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
