Description

Technical Field

[0001] This invention relates to the field of beverage addition devices, and more particularly to a beverage structure with flavor enhancer, a cap, and a beverage bottle. Background Technology

[0002] With the fast pace of modern life, people are increasingly demanding healthier and more diverse beverages. Traditional drinking methods are often limited to plain boiled water. While healthy and harmless, its monotonous and tasteless nature fails to meet consumers' diverse needs for taste and drinking experience. This monotony not only reduces people's willingness to drink water but may also lead individuals to choose beverages containing sugar or other flavorings to compensate for the lack of taste in plain boiled water, thereby increasing health risks such as the incidence of chronic diseases like obesity and diabetes. To address this challenge, a series of technological innovations aimed at improving the drinking experience have emerged in recent years. One popular solution is to integrate a fragrance-enhancing structure into the bottle cap, especially utilizing fragrance release technology to enhance the attractiveness of drinking water through olfactory stimulation, increasing users' interest in drinking. This design not only enriches the flavor of the water but also provides users with a more pleasant and personalized drinking experience without altering the water quality itself.

[0003] However, while existing flavor-enhancing structures offer some flavor enhancement and meet consumer demand to a certain extent, they still present a series of application problems in practice. Firstly, existing flavor-enhancing structures generally employ a flavor ring, where the fragrance is stored in a rigid, ring-shaped shell, which is then fitted onto a flexible cap. External air enters the flavor ring, then the cap, and finally, through a connector in a thin tube, thus enhancing the flavor. However, maintaining smooth airflow requires a rigid flavor ring, a flexible cap, and a rigid connector, all working in tandem with precisely aligned micro-pores to achieve the desired flavor enhancement. This complex assembly suffers from poor stability; whether under normal use or due to accidental impact, displacement or partial detachment is common. This not only results in poor gas supply but may also cause liquid backflow, contaminating the flavor ring. In the long term, this not only affects the consumer's drinking experience but may also pose a potential threat to the safety of drinking water. Because soft bottle caps inevitably deform during use, and there may be issues like incomplete matching when changing flavors, even with various snap-fit ​​designs to simplify the fit, the problem remains largely unresolved, leading to frequent maintenance and a poor user experience. Furthermore, flavoring components are made from materials with varying properties, and the combination of soft and hard materials is greatly affected by material deformation, making leaks particularly prone to occur at the joints. Reverse leakage can then contaminate the flavoring agent through the air duct, further affecting the taste and flavor of the drinking water. Summary of the Invention

[0004] The present invention aims to overcome the problems of easy displacement of existing flavoring structures in the prior art, resulting in poor flavoring effect and easy contamination of the structure.

[0005] The technical solution adopted by this invention is to provide a drinking structure with a flavoring agent, comprising: a hollow shell, a suction structure disposed on the shell, and a liquid channel penetrating the shell and the suction structure. The shell includes: a receiving cavity for placing the flavoring agent, an air inlet connecting the receiving cavity to the outside, and an air outlet connecting the receiving cavity to the liquid channel. A connecting pipe section for connecting an external straw and the liquid channel is provided on the side of the shell away from the suction structure. A limiting structure is provided on the side of the connecting pipe section near the suction structure to limit the length of the external straw entering the liquid channel.

[0006] By placing the aroma enhancer's receiving cavity inside the shell integrated with the suction structure, making it a single unit, this design solves the problems of difficulty in aligning the gas and liquid channels during assembly and easy displacement during use in existing flexible mouthpieces with external aroma rings. This leads to poor connection between the two channels, causing obstructed gas flow and liquid backflow. It overcomes the challenges of maintaining a stable connection between the gas and liquid channels even under normal drinking conditions and accidental impacts, reducing maintenance and preventing aroma ring failure due to improper connection. This lowers costs while improving the overall structural stability.

[0007] The simplified design of the connecting section allows for thorough mixing of the aroma gas and liquid within the liquid channel. The limiting structure facilitates straw installation. Since the mixing of aroma gas and liquid is moved from the original straw connector to the liquid channel, alignment is no longer an issue. This also increases the space for gas and liquid to combine, preventing interference with or obstruction of the air outlet and maintaining smooth flow of the aroma-enhancing gas. Unlike existing technologies that require a straw connector and further matching of the air inlet and outlet during assembly, this solution uses a stepped interface with decreasing cross-section on one side of the housing. This forms the connecting section at the connection point between the liquid channel and the external environment. The minimum cross-sectional size creates a limiting structure, restricting the straw insertion depth and eliminating the need for re-alignment of the thin tube within the liquid channel. This simple and ingenious design achieves the desired functionality.

[0008] Furthermore, the shell comprises an upper shell and a lower shell. The suction structure is connected to the upper shell, and the upper and lower shells merge to form a receiving cavity to accommodate the flavoring agent, facilitating its installation and replacement as needed. The upper shell contains an upper connecting structure, and the lower shell contains a lower connecting structure. One end of the upper connecting structure connects to the suction structure, and the other end is nested within the lower connecting structure. The nesting of the upper and lower connecting structures forms a conduit structure. The liquid channel is located within the conduit structure, and the receiving cavity is separated from the liquid channel by the conduit structure, preventing the flavoring agent and liquid from seeping into each other, thus improving the seal. This ensures both the purity and taste of the drinking water and maintains the freshness and effectiveness of the flavoring agent. Simultaneously, the nesting of the upper and lower connecting structures extends the length of the joint, thereby enhancing the overall waterproof sealing effect of the conduit structure.

[0009] Furthermore, the air inlet is located on the side of the shell, and / or the top surface of the shell, and / or the junction of the side and top surfaces of the shell. An air outlet is located on the side of the conduit structure away from the air inlet. The receiving cavity surrounds the conduit structure and forms at least two guide channels connecting the air inlet and the air outlet respectively. This allows the gas to fully carry out the flavor of the additive. Within a limited space, by increasing the distance between the air inlet and the air outlet, an effective airflow path can be formed, allowing the external airflow to more fully combine with the additive, thereby improving the addition efficiency, making the additive volatilize more evenly, and improving the persistence and stability of the olfactory sensation. The upper shell has a partition cavity surrounding the upper connecting structure. The nested interface formed by the upper and lower connecting structures is connected to the partition cavity. After assembly, the partition cavity forms an air barrier connecting the nested interface. This air barrier can further utilize its own gas pressure to improve the waterproof sealing effect of the conduit structure, effectively preventing liquid from passing through the gaps and contaminating the flavoring agent.

[0010] Furthermore, the conduit structure forms a cylindrical rigid support within the shell, meeting the basic requirements for liquid transfer while resisting external pressure or impact. A matching plane is provided on one side of the conduit structure, with the vent located on this plane. A flexible sleeve is fitted onto the conduit structure, matching the vent on the matching plane. This matching plane facilitates installation and, more importantly, alters the direction of pull on the vent during the fitting process. The flexible sleeve serves as both a carrier for the unidirectional flow structure and a sealing structure for the conduit structure. Therefore, the flexible sleeve needs to expand during the sealing process to achieve a tight fit. However, the tensile force generated by this expansion, if applied to the curved surface, could easily deform the vent. By providing a flat end to support the vent, the tensile force after assembly is effectively guided, ensuring the vent only experiences horizontal pull. Simultaneously, this creates unidirectional flow from the receiving cavity to the liquid channel, further protecting the dryness of the receiving cavity and preventing liquid from entering, thus extending the shelf life of the flavoring agent.

[0011] Furthermore, the flexible sleeve is a ring-shaped elastic element. One end of the flexible sleeve is connected to the upper shell, and the other end is connected to the lower shell. After the upper shell and the lower shell are assembled, the lower edge of the upper connecting structure abuts against the inner ring, and the flexible sleeve forms a block from the outside of the outer ring, thereby sealing the partition cavity and forming a sealed area, which further improves its sealing effect.

[0012] The flexible socket is specifically an elastic sealing ring, which includes: a planar segment that mates with the mating plane, and an arc-shaped segment that connects to the beginning and end of the planar segment. The design of the planar segment reduces the processing difficulty of the vent hole, and the combination of the planar segment and the arc-shaped segment solves the requirement of planar matching for the annular flexible socket.

[0013] The planar section has a spherical self-sealing structure, and the vent is a conical channel. The cross-section of the conical channel near the liquid channel is smaller than the cross-section away from the liquid channel. The self-sealing structure matches the conical channel and is embedded in the conical channel. The self-sealing structure includes a self-closing slit. The conical channel and the slit cooperate to form a one-way conduction structure from the receiving cavity to the liquid channel, so that the slit can only open to the side with the smaller cross-section (i.e., the direction of the liquid channel) and is difficult to open in reverse, thereby further improving the sealing effect.

[0014] Furthermore, the container cavity contains flavoring agents to add aroma to the liquid. The lower shell also features an external connecting structure. This external connecting structure, along with a matching cover, allows for quick installation and replacement of the shell to accommodate a wider range of containers. The suction structure's surface has a raised ridge extending towards the air inlet, while the side away from the ridge has a concave arc surface. The ridge and arc surface form an ergonomic gripping area, facilitating rotation and installation of the drinking mechanism. Simultaneously, the raised ridge effectively strengthens the connection between the upper shell and the suction structure, increasing the overall strength of the shell. The concave arc surface forms a protrusion on the back side, further enhancing the overall structural strength to resist bending and prevent displacement or deformation of the air inlet. When an adsorption force is applied to the suction structure, a small portion of the suction acts on the air inlet, allowing external air to enter the container cavity through the air inlet, carrying the aroma of the flavoring agents out. The scented air then enters the liquid channel through the air outlet and flows towards the suction structure.

[0015] The second technical solution adopted by this invention is to provide a bottle cap, including a cap base and a flavoring-enhancing drinking structure as described in the previous technical solution. By combining the flavoring-enhancing drinking structure with the bottle cap, users can apply the drinking structure to various types of drinking bottles without any modification or customization of the bottle body, thereby improving its practicality and convenience. At the same time, the matching design of the cap base and the drinking structure not only ensures the stability and reliability of the drinking structure during use, but also allows users to easily assemble and replace it. Users only need to simply install the drinking structure on the cap base to connect it to the drinking bottle, without complicated operations or tools. Furthermore, since the drinking structure and cap are detachable, users can easily change flavors and clean and maintain them, which is not only convenient to use, but also ensures hygiene and safety during use.

[0016] Furthermore, the cover includes a recessed mounting position where the drinking structure is positioned, allowing it to be embedded within the cover. This not only saves space but also strengthens the connection between the drinking structure and the cover, while also providing additional protection for the drinking structure. The cover also includes a connection channel that runs through it and connects to the liquid channel. A sealing ring is installed between the drinking structure and the cover to improve the sealing performance. This not only prevents liquid leakage but also ensures a stable flow of drinking water into the housing, improving the transmission efficiency.

[0017] Furthermore, the cap features a recessed fitting on its side and an elastic sealing ring fitted onto the fitting. The elastic sealing ring has several air channels. By designing the recessed fitting and the elastic sealing ring, along with the air channels on the elastic sealing ring, a balance of air pressure inside and outside the drinking bottle is achieved. This is especially important when the user is drinking or drinking continuously, because as the liquid in the bottle decreases, the air pressure inside gradually decreases, increasing the difficulty of sipping. The air channels allow outside air to enter the bottle, replenishing the air pressure lost due to the decreasing liquid volume, making the sipping process easier and smoother, while also preventing problems such as liquid splashing or leakage caused by pressure imbalance.

[0018] The third technical solution adopted by the present invention is to provide a drinking bottle, including a bottle body and a connecting tube, as well as a cap for a drinking bottle as described in the second technical solution above. The cap is placed on the bottle mouth of the bottle body, one end of the connecting tube is connected to the cap seat and communicates with the liquid channel, and the other end extends into the bottle body.

[0019] Compared with existing technologies, the beneficial effects of this invention are as follows: By adopting a design that combines an upper shell and a lower shell to form a receiving cavity, and by using the nested cooperation of the upper and lower connecting structures to form a conduit structure, the mutual seepage of flavoring agents and liquids is effectively avoided, ensuring the purity and taste of drinking water, while maintaining the freshness and effectiveness of the flavoring agents. Furthermore, the air barrier further enhances the waterproof sealing effect of the conduit structure, improving the overall performance of the product. Regarding enhancing gas channel efficiency, the rational layout of the air inlet and outlet holes and the design of the guiding channel allow external airflow to more fully combine with the flavoring agents, improving addition efficiency, resulting in more uniform evaporation of the flavoring agents, and enhancing the persistence and stability of the olfactory sensation.

[0020] By designing two or more guide channels connecting the air inlet and outlet, the gas fully carries the flavoring agent. Within a limited space, increasing the distance between the air inlet and outlet creates an effective airflow path, improving addition efficiency and resulting in more uniform evaporation of the flavoring agent, thus enhancing the persistence and stability of the olfactory experience. The conduit structure forms a rigid support within the shell, resisting external pressure or impact, preventing functional failure or safety hazards caused by shell deformation, and enhancing the overall structural stability of the shell. Flexible fittings on the conduit structure create a one-way liquid channel, preventing liquid from flowing back into the receiving cavity through the outlet, maintaining the purity of the drinking water and extending the lifespan of the flavoring agent.

[0021] By combining the flavor-enhancing drinking mechanism with the bottle cap, users can apply this mechanism to various types of drinking bottles without any modification or customization, improving its practicality and convenience. Furthermore, the drinking mechanism and cap are detachable, allowing users to easily change flavors and perform cleaning and maintenance. The cap base features a recessed fitting on its side and an elastic sealing ring fitted onto the fitting. The elastic sealing ring has several air channels to balance the air pressure inside and outside the drinking bottle, making the water intake process easier and smoother, and preventing liquid splashing or leakage caused by pressure imbalance.

Detailed Implementation

[0040] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0041] Example 1

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a drinking structure with flavoring agents, including: a shell 100 and an absorption structure 101 disposed on the shell 100, and a liquid channel 102 penetrating the shell 100 and the absorption structure 101. The shell 100 is detachably divided into a hollow upper shell 120 and a hollow lower shell 130. The upper shell 120 has an upper connecting structure 121, and the upper shell 120 is integrally formed with the absorption structure 101 and the upper connecting structure 121. The lower shell 130 has a lower connecting structure 131, and the lower shell 130 is integrally formed with the lower connecting structure 131. The hollow upper shell 120 and the hollow lower shell 130 are tightly connected by means of threaded connection, snap-fit ​​connection or sleeve connection, etc. Figure 3 and Figure 5As shown, the upper and lower parts enclose the inside of the housing 100 to form a sealed annular cavity 103, which is used to hold the flavoring agent. On the side of the housing 100 away from the suction structure 101, there is a connecting pipe section 104 for connecting an external straw and a liquid channel. On the side of the connecting pipe section 104 near the suction structure, there is a limiting structure 105, which is used to limit the length of the external straw that enters the liquid channel 102.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the upper connecting structure 121 is a cylindrical tube, with its lower edge extending to the middle of the air outlet 112. The lower connecting structure 131 is a cylindrical tube matching the upper connecting structure 121, and includes an inner ring 143 and an outer ring 144 connected together, with the outer ring 144 being higher than the inner ring 143. The inner ring 143 abuts against the lower edge of the upper connecting structure 121, and the inner diameter of the upper connecting structure 121 is smaller than the inner diameter of the inner ring 143, so that the partial protrusion of the upper connecting structure 121 into the liquid channel 102 forms a secondary limiting of the straw. The inner wall of the outer ring 144 fits against the outer wall of the upper connecting structure 121, so that the upper connecting structure 121 is nested within the lower connecting structure 131.

[0044] The conduit structure is designed with a smooth inner wall to form a liquid channel 102, which separates the liquid channel 102 from the receiving cavity 103. The housing 100 has an air inlet 111 for connecting the receiving cavity 103 to the outside; the diameter of the air inlet 111 on the outside of the receiving cavity 103 is larger than the internal diameter of the receiving cavity 103. The conduit structure also has an air outlet 112 for connecting the receiving cavity 103 to the liquid channel 102. The housing 100 is made of food-grade high-strength plastic.

[0045] The number of air inlets 111 is at least one or more. The air inlets 111 can be located on the side surface outside the housing 100 receiving cavity 103, on the top surface outside the housing 100 receiving cavity 103, or at the junction of the side surface and the top surface outside the housing 100 receiving cavity 103. The shape of the air inlet 111 can be circular, elliptical, rectangular, strip-shaped, or waist-shaped, etc., and can be selected according to actual application needs. In this embodiment, there is one air inlet 111, which is strip-shaped and located on the side surface outside the housing 100 receiving cavity 103.

[0046] like Figure 5 , Figure 6 and Figure 7As shown, the air outlet 112 is located on the side of the conduit structure away from the air inlet 111. The receiving cavity 103 surrounds the lower connecting structure 131 and forms at least two guide channels that respectively connect the air inlet 111 and the air outlet 112, so that the gas travels as far as possible in the receiving cavity 103, fully carrying out the fragrance from the receiving cavity 103 and then entering the liquid channel 102 from the air outlet 112.

[0047] The suction structure 101 includes a suction nozzle and a structural cavity. The suction nozzle is located at the end away from the upper shell 120 and forms a liquid channel 102 suction port. The structural cavity communicates with the upper shell 120. The upper end of the upper communicating structure 121 is connected to the suction nozzle, and the lower end of the upper communicating structure 121 mates with the lower communicating structure 131. A gap is left between the upper communicating structure 121 and the inner wall of the structural cavity, which forms a partition cavity 122. The nested interface formed by the upper communicating structure 121 and the lower communicating structure 131 communicates with the partition cavity 122. The conduit structure forms a cylindrical rigid support within the housing 100. A matching plane 132 is provided on one side of the conduit structure, and an air outlet is provided on the matching plane 112. A flexible sleeve 140 is fitted onto the conduit structure. The flexible sleeve 140 includes a planar segment 141 that mates with the matching plane 132, and an arc-shaped segment 142 that connects end to end with the planar segment 141. The planar segment 141 has a spherical self-sealing structure. The air outlet 112 is a conical channel. The cross-section of the conical channel near the liquid channel 102 is smaller than the cross-section away from the liquid channel 102. The self-sealing structure matches the conical channel and is embedded in the conical channel. The self-sealing structure includes a self-closing cut 150. The conical channel and the cut 150 cooperate to form a unidirectional passage from the receiving cavity 103 to the liquid channel 102. The flexible sleeve 140 is an annular elastic element. One end of the flexible sleeve 140 is connected to the upper connecting structure 121 of the upper shell 120, and the other end is connected to the lower connecting structure 131 of the lower shell 130. After the upper shell 120 and the lower shell 130 are assembled, the lower edge of the upper connecting structure 121 abuts against the inner ring 143, and the flexible sleeve 140 forms a block from the outside of the outer ring 144. The height of the flexible sleeve 140 is equal to the height inside the receiving cavity 103 after the upper and lower shells 130 are fitted together.

[0048] like Figure 8As shown, the conductive structure protrudes into the air outlet 112 from one side of the flexible sleeve 140. The conductive structure has a self-sealing cutout 150, which is a cross-shaped cutout. The receiving cavity 103 is connected to the liquid channel 102 in one direction through the cutout 150. When the user draws water through the suction structure 101, external suction acts on the cross-shaped cutout 150, which opens using its elastic properties, allowing gas (carrying the fragrance of the flavoring agent) to pass through, thus achieving unidirectional conduction. When the user stops drawing water, the cross-shaped cutout 150 returns to its normal self-sealing state using its elasticity, ensuring effective isolation between the flavoring agent and the liquid channel 102.

[0049] The cavity 103 contains a flavoring agent, which may be a solid flavoring packet, flavoring ring, or flavoring granules, and can be adjusted according to actual application requirements.

[0050] The lower shell 130 is also provided with an external connection structure 170. The external connection structure 170 can be a thread, a snap, an annular protrusion, an annular groove, a transition fit, etc., which can be adjusted according to actual application requirements.

[0051] like Figure 2 As shown, a gripping part 110 is also provided between the suction structure 101 and the housing 100. The surface of the suction structure 101 is provided with a ridge 1011 extending towards the air inlet. The side of the suction structure 101 away from the ridge 1011 is provided with a concave arc surface 1012. The ridge 1011 and the arc surface 1012 form the gripping part 110. When an adsorption force is applied to the suction structure 101, a small part of the adsorption force will act on the air inlet 111, so that external air enters the receiving cavity through the air inlet 111, bringing out the fragrance of the flavoring agent, and entering the liquid channel 102 through the air outlet 112.

[0052] Example 2

[0053] like Figure 9 and Figure 10 As shown, this embodiment provides a cap for a drinking bottle, including: a cap base 200, and a drinking structure with flavoring agent as described in Embodiment 1, wherein the drinking structure is coupled into the cap base 200. The cap base 200 is circular or other shapes that conform to the bottle mouth size, and its edge is designed with a fitting structure that tightly connects with the bottle mouth. This fitting structure can be a thread, snap, protrusion, groove, or transition fit, etc., and can be adjusted according to the actual bottle mouth structure to ensure sealing and stability.

[0054] like Figure 10 , Figure 11 and Figure 12As shown, the cover 200 has a recessed mounting position 201 in the middle. The depth and diameter of the mounting position 201 are adapted to the drinking structure with flavor enhancer described in Embodiment 1. The connecting structure 202 penetrates the cover 200. The connecting structure 202 is a cylindrical channel penetrating the bottom of the cover 200. Its diameter matches the liquid channel 102 in the drinking structure to ensure that the two can be seamlessly connected. One end of the connecting structure 202 opens at the bottom of the mounting position 201 and connects to the liquid channel 102, while the other end extends to the bottom of the cover 200.

[0055] The drinking mechanism, as the core component of the cap, has its housing 100 (including the upper housing 120 and the lower housing 130) installed inside the cap base 200, achieving a secure connection through threads, snaps, or sleeves. The top of the upper housing 120, i.e., the mounting position 201 of the suction structure 101, is slightly raised above the surface of the cap base 200 for easy user operation, while the lower housing 130 is flush against the bottom of the cap base 200. A sealing ring 210 is also provided between the drinking mechanism and the cap base 200. The bottom of the cap base 200 has a sealing groove for placing the sealing ring 210. The sealing ring 210 is an annular elastic sealing ring 210, which surrounds the connecting structure 202. Additionally, there is a gap between the housing 100 and the cap base 200 to facilitate air intake.

[0056] The edges of the mounting position 201 are designed with a slight bevel or chamfer to facilitate the installation and removal of the drinking structure.

[0057] like Figure 10 and Figure 13 As shown, the upper diameter of the cover 200 is larger than the lower diameter. Recessed fitting positions 203 are provided on the upper part of the side surface of the cover 200 and in the transition area between the upper and lower parts. Specifically, the fitting position 203 on the upper side surface of the cover 200 is notched, while a recessed annular fitting position 203 is provided in the middle area between the upper and lower parts.

[0058] A resilient sealing ring 220, matching in shape and size, is fitted onto this annular socket 203. This resilient sealing ring 220 is divided into upper, middle, and lower parts. The upper part tightly covers the notch-shaped socket 203 on the upper side of the cover 200, and its height is flush with the top surface of the cover 200. The middle and lower parts fit into the concave annular socket 203 between the upper and lower parts of the cover 200. The diameter of the middle part of the resilient sealing ring 220 is equal to the diameter of the upper side of the cover 200, while the diameter of the lower part matches the diameter of the lower side of the cover 200. Furthermore, several straight air passages 221 are provided on the upper part of the resilient sealing ring 220, which covers the notch socket 203 on the upper part of the cover 200, and a notch is also provided on the lower part of the cover 200 to allow for smooth airflow through the air passages 221. During installation, the elastic sealing ring 220 is fitted onto the socket 203 and, with its own elasticity, fits tightly against the inner wall of the socket 203, improving the sealing performance of the entire drinking bottle cap and ensuring that users can enjoy a smoother and easier water absorption experience during continuous drinking.

[0059] Example 3

[0060] like Figure 14 and Figure 15 As shown, this embodiment provides a drinking bottle, including a bottle body 300 and a connecting tube 310, and also includes a cap as described in Embodiment 2, disposed on the bottle mouth of the bottle body 300. The bottle body 300 can be adjusted and designed into various shapes to meet the capacity specifications according to actual needs, and its material can be food-grade plastic or glass to ensure safety and durability. The bottom of the bottle body 300 is stable and easy to place; the bottle body is smooth and easy to clean.

[0061] like Figure 16 and Figure 17 As shown, the connecting tube 310 can be designed as a rigid tube or a flexible tube according to actual needs. One end of it is designed with a connection interface that matches the cap 200, for a tight connection with the connection channel 202 on the cap 200, ensuring that the liquid can flow smoothly from the bottle 300 to the liquid channel 102. The other end of the connecting tube 310 extends into the bottle 300.
