Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0020] To facilitate understanding of the anti-overflow component provided in this application embodiment, its application scenario is first described. The anti-overflow component provided in this application embodiment is applied to a beverage cup used to hold common beverages such as milk, water, and juice for children. However, current anti-overflow components still experience splashing when used with beverage cups. Therefore, this application embodiment provides an anti-overflow component to improve its performance. A detailed description follows with reference to the accompanying drawings and embodiments.

[0021] First, let me introduce the main structure of the beverage cup, for reference. Figure 1 As shown, the beverage cup mainly includes a cup body 100 and a cup lid. The cup body 100 is used to hold beverages, such as milk, water, or juice. The cup lid is detachably and fixedly connected to the cup body 100 to seal the opening of the cup body 100. For example, the cup lid and cup body 100 can be connected by threads; the cup lid is placed on the cup body 100, and rotating the cup lid secures the connection. Alternatively, the cup lid and cup body 100 can be fixedly connected by a snap-fit ​​mechanism. For instance, one side of the cup lid is hinged to the cup body 100, while the opposite side has a snap-fit ​​mechanism. When closed, the snap-fit ​​mechanism engages with the cup body 100, thus achieving a fixed connection. It should be understood that in addition to the connection between the cup lid and cup body 100 as shown in the above example, other connection methods can be used, which will not be illustrated here.

[0022] It should be noted that the anti-overflow component 300 in this embodiment is disposed on the cup lid. In one example, when the anti-overflow component 300 is applied to a beverage cup, the anti-overflow component 300 and the middle ring 200 form a cup lid, wherein the middle ring 200 is connected to the cup body 100. After the middle ring 200 is connected to the cup body 100, the anti-overflow component 300 communicates with the space inside the cup body 100. When a child uses the cup, sucking on the anti-overflow component 300 allows the beverage to flow from the anti-overflow component 300 into the child's mouth.

[0023] refer to Figure 2 and Figure 3 As shown, Figure 2 A perspective view of the anti-overflow component provided in an embodiment of this application is shown. Figure 3 A cross-sectional view of the anti-overflow assembly provided in this application embodiment is shown. The anti-overflow assembly provided in this application embodiment mainly includes a straw 10 and a base 20, wherein the base 20 serves as a support structure to support the straw 10. The straw 10 is connected to the base 20 to guide the beverage in the cup 100 to the child's mouth.

[0024] In a specific configuration, the base 20 contains a receiving cavity 22, the opening of which faces away from the straw 10. After the cup lid is connected to the cup body 100, the receiving cavity 22 communicates with the space inside the cup body 100, and the straw 10 communicates with the receiving cavity 22. Therefore, a flow channel is formed by the cup body 100, the receiving cavity 22, and the straw 10, allowing the beverage to flow from the cup body 100 through this flow channel into the child's mouth. In one example, the anti-overflow component 300 and the middle ring 200 form the cup lid. In this case, the base 20 has a slot, and the middle ring 200 has a through hole that matches the base 20. The base 20 can be inserted into the through hole, and the slot engages with the middle ring 200. It should be understood that the assembly method of the base 20 can be similar to the assembly method of a nipple on the middle ring 200.

[0025] For ease of description, the two opposite ends of the straw 10 are defined as the outlet 11 and the inlet 12, respectively. The end of the straw 10 that communicates with the receiving cavity 22 is the inlet 12, and the end of the straw 10 that protrudes from the base 20 is the outlet 11. When using the straw, children can suck on the outlet 11 to allow the drink to flow into their mouths. Furthermore, when arranging the straw 10, a portion of the straw 10 protrudes from the base 20 and has a certain length, thus creating a certain distance between the outlet 11 and the base 20 to facilitate children sucking on the straw 10.

[0026] The anti-overflow assembly provided in this embodiment further includes a valve 30, which is disposed on the straw 10 and located at one end of the receiving cavity 22 near the straw 10, that is, the valve 30 is disposed on the straw 10 near the inlet 12. The valve 30 is a unidirectional valve under negative pressure, and its conduction direction is from the receiving cavity 22 to the straw 10, that is, from the outlet 12 to the inlet 11.

[0027] In its specific design, the valve 30 has a slit 31, which can be opened by the elastic deformation of the valve 30, thus enabling the valve 30 to conduct. During use, when a child sucks on the straw 10, the air pressure near the outlet 11 inside the straw 10 is lower than the air pressure near the inlet 12, creating a negative pressure. Under this negative pressure, the valve 30 undergoes elastic deformation, opening the slit 31 and allowing the child to smoothly suck up the beverage. When the child stops sucking, the pressure on both sides of the valve 30 returns to equilibrium, the valve 30 returns to its initial state, and the slit 31 closes, preventing liquid from leaking from inside the cup 100 through the straw to the outside of the cup 100.

[0028] When the valve 30 is positioned on the straw 10 near the inlet 12, the distance between the valve 30 and the outlet 11 of the straw 10 can be increased. This can effectively reduce the path length of the beverage after passing through the valve 30 and splashing out of the outlet 11, thus achieving a certain buffering effect and reducing the occurrence of splashing.

[0029] Furthermore, the valve 30 opens using negative pressure. For example, the valve 30 can open when the negative pressure reaches 8 kPa or higher, but cannot open below 8 kPa. Under suction, the valve plate of the valve 30 deforms towards the outlet 11, thus enabling unidirectional flow. In contrast, valves in the prior art are located near the outlet, and their opening method relies on a child biting the valve to cause elastic deformation and open it. Compared to the valve opening method in the prior art, the valve provided in this embodiment opens using negative pressure, eliminating the need for biting and relying solely on the child's sucking force to open. This improves the durability of the valve and prevents it from being damaged by biting.

[0030] When setting the valve 30, the valve 30 can be located inside or outside the straw 10, as long as it is far from the outlet 11. For example, the valve 30 is located inside the straw 10 and close to the inlet 12 of the straw 10; or the valve 30 is exposed outside the straw 10 and communicates with the outlet 11. For example, the valve 30 is located at the end of the straw 10 located within the receiving cavity 22, and / or the valve 30 is located on the straw 10 and at the connection between the straw 10 and the base. When the valve 30 is exposed outside the straw 10, the distance between the valve 30 and the outlet 11 of the straw 10 can be maximized. Furthermore, although the valve 30 is located outside the straw 10, since the inlet 12 of the straw 10 is located within the receiving cavity 22, the valve 30 can still be protected by the sidewall of the base 20, improving the safety of the valve 30. When the valve 30 is placed on the straw 10 and located at the connection between the straw 10 and the base, it can prevent children from biting the valve 30 during use, thereby improving the service life of the valve.

[0031] As can be seen from the above description, the anti-overflow component provided in this application embodiment reduces splashing by providing a valve 30 at the end of the straw 10 away from the liquid outlet 11, thereby improving the effectiveness of the anti-overflow component and preventing children from choking during drinking. Furthermore, the straw 10 and base 20 are integrated in this application embodiment, facilitating the assembly of the anti-overflow component with the middle ring 200, making the anti-overflow component compatible with beverage cups originally equipped with nipples.

[0032] In an alternative embodiment, the end of the valve 30 facing the outlet 11 of the straw 10 is connected to the straw 10, and a gap exists between the edge of the end of the valve 30 facing away from the outlet 11 and the inner wall or an extension of the inner wall of the straw 10. In this embodiment, the valve 30 is only connected to the straw 10 at the outlet 11, while other parts are not connected to the inner wall of the straw 10. This ensures that the valve 30 has good deformation capacity during deformation, and the gap 31 of the valve 30 can be opened even with a small suction force. For example, the valve 30 is an inverted truncated structure, that is, the end of the valve 30 facing the outlet 11 is larger than the end of the valve 30 away from the outlet 11, so that there is a gap between the end of the valve 30 away from the outlet 11 and the inner wall or the extension surface of the inner wall of the straw 10, so that the valve 30 can be deformed with a small suction force.

[0033] Continue to refer to Figure 2 and Figure 3As shown, in the specific arrangement of the straw 10, the straw 10 can partially extend into the receiving cavity 22 to maximize the length of the straw 10, thereby increasing the space within the straw 10 to accommodate splashed liquid and improving the splashing situation. For example, one end of the straw 10 communicating with the receiving cavity 22 (the inlet 12) extends into the receiving cavity 22 and protrudes within it. With this structure, the length between the inlet 12 and the outlet 11 of the straw 10 can be further increased, and the valve 30 can be positioned further away from the outlet 11, effectively improving the splashing situation. Furthermore, with the above structure, partially concealing the straw 10 within the receiving cavity 22 of the base 20 reduces the length of the straw 10 exposed outside the base 20, making it easier for children to suckle.

[0034] In one feasible embodiment, the base 20 and the straw 10 can be manufactured as a single unit. When manufactured in this manner, the valve 30, straw 10, and base 20 can be integrally injection molded, thereby improving the structural strength of the anti-overflow assembly and the connection strength between the components. Specifically, it can be manufactured using an elastic material, such as rubber or a rubber-like material.

[0035] In an optional embodiment, the distance between the valve 30 and the outlet 11 of the straw 10 provided in this application embodiment is greater than 12 mm. For example, the distance between the valve 30 and the outlet of the straw 10 can be 12.5 mm, 12.7 mm, 13 mm, 13.5 mm, etc. Using the above dimensions can reduce the probability of splashing and improve the effectiveness of the anti-overflow component. It should be understood that in this application embodiment, the distance between the valve 30 and the outlet 11 of the straw 10 is specifically the distance from the gap 31 of the valve 30 to the outlet 11.

[0036] When specifically setting the valve 30, at least one slit 31 is provided on the valve 30. For example, the number of slits 31 can be one, two, three, or other different numbers. When there is one slit 31, a straight slit is formed; when there are two slits 31, an X-shaped slit can be formed; and when there are three slits 31, a Y-shaped slit can be formed. Of course, the slit 31 in this application is not limited to the specific examples mentioned above, and other types of slits can also be used. The specific slits can be set as needed, as long as they facilitate children's sucking out of water and prevent splashing.

[0037] In an optional embodiment, the valve 30 provided in this application further includes reinforcing ribs 34, which are positioned on opposite sides of the slit 31. These reinforcing ribs 34 enhance the driving force for closing the slit 31, ensuring a stable seal when the child is not sucking on the straw 10. Furthermore, the reinforcing ribs 34 protrude outwards from the side of the valve 30 opposite to the liquid outlet 11 of the straw 10. This arrangement prevents the reinforcing ribs 34 from interfering with other components when the slit 31 is open, facilitating its opening.

[0038] When specifically arranging the slit 31, the slit 31 is located at the tip of the protruding valve 30. Arranging it at this position facilitates opening when the valve 30 undergoes elastic deformation.

[0039] In one specific implementation, the valve 30 provided in this embodiment is a V-shaped structure. For ease of description, the two sidewalls of this V-shaped structure are respectively named the first valve plate 32 and the second valve plate 33. Taking the slit 31 as an example, the slit 31 is located between the first valve plate 32 and the second valve plate 33. When the valve 30 undergoes elastic deformation, the first valve plate 32 and the second valve plate 33 undergo elastic deformation, thereby opening the slit 31. When the first valve plate 32 and the second valve plate 33 return to their initial state, the slit 31 is sealed by the first valve plate 32 and the second valve plate 33.

[0040] For example, when the valve 30 is set, the angle between one side of the V-shaped structure of the valve 30 and the sidewall of the straw 10 is between 45 degrees and 80 degrees. That is, the angle between the first valve plate 32 or the second valve plate 33 and the sidewall of the straw 10 is between 45 degrees and 80 degrees. For example, the angle between the first valve plate 32 and the sidewall of the straw 10 can be any angle between 45 degrees and 80 degrees, such as 45 degrees, 50 degrees, 60 degrees, 70 degrees, or 80 degrees. When the above method is adopted, both the first valve plate 32 and the second valve plate 33 are tilted relative to the sidewall of the straw 10, thereby facilitating the elastic deformation of the first valve plate 32 and the second valve plate 33 under the action of air pressure.

[0041] In one alternative arrangement, the first valve plate 32 and the second valve plate 33 are symmetrically arranged, making the valve 30 a symmetrical structure. This arrangement ensures that when the valve 30 deforms, the elastic deformation of the first valve plate 32 and the second valve plate 33 is approximately equal, facilitating the opening of the slit 31. Simultaneously, it allows the slit 31 to be approximately located at the center line of the straw 10, making it easier for the slit 31 to open when the child sucks.

[0042] In one optional embodiment, the thickness of the valve 30 is between 0.3 mm and 1.2 mm. For example, the thickness of the valve 30 can be any thickness between 0.3 mm and 1.2 mm, such as 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, or 1.2 mm. The thickness of the reinforcing rib 34 is between 0.8 mm and 2 mm. For example, the thickness of the reinforcing rib 34 can be any thickness between 0.8 mm and 2 mm, such as 0.8 mm, 1 mm, 1.5 mm, 1.7 mm, or 2 mm. Using the above-mentioned thickness ensures that the valve 30 has good elastic properties, allowing it to undergo effective elastic deformation when needed, thus opening the gap 31. When the valve 30 does not need to open, its elastic properties ensure that the gap 31 is sealed.

[0043] Of course, the thickness of the valve 30 and the range of the inclination angle between the sidewall of the valve 30 (first valve plate 32, second valve plate 33) and the sidewall of the straw 10 in the above example can all meet the range of the above example, so that the thickness of the valve 30 and the inclination angle of the sidewall of the valve 30 can be matched to the child's sucking force, ensuring that the valve 30 can be opened even when the young child uses a smaller sucking force.

[0044] Continue to refer to Figure 1 and Figure 4 As shown, the base 20 provided in this embodiment of the application also has a locking protrusion 23, which is located in the receiving cavity 22 and divides the receiving cavity 22 into a first receiving cavity 221 and a second receiving cavity 222. The first receiving cavity 221 is away from the straw 10, while the second receiving cavity 222 is close to the straw 10. When the anti-overflow assembly is connected to the cup body 100, the first receiving cavity 221 communicates with the cup body 100, while the second receiving cavity 222 communicates with the straw 10.

[0045] The aforementioned engaging protrusion 23 is used to connect the connecting tube 400, which can be considered an extension of the straw 10. When assembling the connecting tube 400, it engages and is fixed with the engaging protrusion 23, and a sealed connection is formed between the engaging protrusion 23 and the connecting tube 400. This allows the beverage in the cup 100 to enter the straw 10 through the connecting tube 400 when the straw 10 is being sucked. Using this method, children can suck on the beverage without tilting the cup 100.

[0046] In a specific configuration, the engaging protrusion 23 is an annular structure formed within the receiving cavity 22, and the hollow area of ​​this annular structure serves as the space for mating with the connecting tube 400. The connecting end of the connecting tube 400 is inserted into the engaging protrusion 23 and pressed and sealed against the sidewall of the engaging protrusion 23. In an optional embodiment, the shape of the second receiving cavity 222 provided in this application matches the shape of the connecting end of the connecting tube 400. When the connecting end is inserted into the second receiving cavity 222, the connecting end fills the second receiving cavity 222 to ensure the stability of the connecting tube 400 after assembly. In addition, when the above method is adopted, the connecting end of the connecting tube 400 avoids the valve 30 to provide sufficient space for the deformation of the valve 30. For example, when the connecting end is inserted into the second receiving cavity 222, the liquid inlet 12 of the straw 10 is located inside the connecting end.

[0047] Continue to refer to Figure 3 and Figure 4 As shown, the embodiments provided in this application also include an air inlet valve 21. Specifically, an air inlet valve 21 is provided on the base 20 to connect the receiving cavity 22 with the outside of the base 20. This air inlet valve 21 is used to regulate the air pressure inside and outside the base 20. When the anti-overflow assembly is assembled to the middle ring 200, the air inlet valve 21 adjusts the air pressure difference inside and outside the cup body 100, thereby facilitating sucking by children. For example, the air inlet valve 21 is a one-way valve, with its direction of flow from outside the base 20 to inside the base 20. In the specific configuration of the air inlet valve 21, the air inlet valve 21 is connected to the first receiving cavity 221. The number of such valves can be one or two. Figure 4 As shown, there are two intake valves 21, and the two intake valves 21 are symmetrically distributed on both sides of the straw 10.

[0048] This application embodiment also provides a beverage cup, which includes a cup body 100 and a middle ring 200, and also includes any of the above-mentioned anti-overflow components; The anti-overflow assembly is fixedly connected to the middle ring 200, and the anti-overflow assembly is sealed to the cup body 100; wherein, the receiving cavity 22 is connected to the space inside the cup body 100.

[0049] In the above technical solution, the anti-overflow component provided in this application embodiment reduces splashing by setting a valve 30 at the end of the straw 10 away from the liquid outlet 11, thereby improving the effectiveness of the anti-overflow component and preventing children from choking during drinking. Furthermore, the straw 10 and base 20 are integrated in this application embodiment, facilitating the assembly of the anti-overflow component with the middle ring 200, making the anti-overflow component compatible with beverage cups originally equipped with nipples.
