Description

Technical Field

[0001] This utility model relates to the field of drinking bottle technology, and in particular to a bottle cap and drinking bottle with a liftable spout. Background Technology

[0002] With the increasing popularity of portable drinking vessels, drinking bottles with built-in straws are widely used in daily life due to their convenience and good sealing. In existing technology, these bottles typically feature a liftable straw structure on the cap to allow for both concealment and extension of the straw, thus balancing hygiene and ease of use. To control the straw's maximum upward position and ensure stability during normal use, current designs often employ a detachable retaining ring on the outside of the straw. When the straw is pushed upward to a preset height, this retaining ring engages with the internal structure of the cap, preventing further upward movement. However, this structure not only increases the number of parts and the complexity of the assembly process but also leads to increased mold and production costs, hindering mass production and cost control. Furthermore, the pull rings on existing caps are usually single-function, used only for lifting and carrying the container, failing to integrate with other structures and leaving room for further optimization and improvement. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a bottle cap and drinking bottle with a lifting spout that is compact in structure, low in production cost and highly integrated in function.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide a bottle cap with a lifting suction nozzle, comprising:

[0005] The bottle cap body has a guide channel extending in a vertical direction, and the inner wall of the guide channel has a first limiting structure extending in the direction of its axis.

[0006] The suction nozzle structure is vertically and flexibly inserted into the guide channel. The outer wall of the suction nozzle structure has an integrally formed first and second engaging portion. The first and second engaging portions are spaced apart along the axial direction of the suction nozzle structure, forming a first gap between them to accommodate the first limiting structure. The second engaging portion is configured to elastically deform in the horizontal direction. When the suction nozzle structure rises to a first preset position, the second engaging portion engages with the lower surface of the first limiting structure, restricting the suction nozzle structure from rising further. When the suction nozzle structure descends to a second preset position, the first engaging portion engages with the upper surface of the first limiting structure, restricting the suction nozzle structure from descending further.

[0007] In the bottle cap with a lifting nozzle described above, the nozzle structure includes a snap-fit ​​body, and a second snap-fit ​​part is vertically disposed on the outer wall of the snap-fit ​​body and forms a second gap with the snap-fit ​​body. The second gap is configured to allow the second snap-fit ​​part to elastically deform toward the snap-fit ​​body when subjected to an external force.

[0008] In the bottle cap with a lifting nozzle described above, the first snap-fit ​​portion is horizontally disposed on the outer wall of the snap-fit ​​body and protrudes toward the inner wall of the guide channel, and the end of the second snap-fit ​​portion away from the first snap-fit ​​portion protrudes toward the inner wall of the guide channel.

[0009] In the bottle cap with a lifting nozzle described above, the guide channel is provided with a second limiting structure extending along its inner wall toward the axis at one end away from the first snap-fit ​​part. A vertically arranged nozzle reset member is provided in the second gap. One end of the nozzle reset member abuts against the snap-fit ​​body, and the other end abuts against the second limiting structure.

[0010] In the bottle cap with a lifting nozzle described above, the second limiting structure is arranged in a ring along the inner wall of the guide channel and has at least one notch for the second snap-fit ​​portion to pass through.

[0011] In the aforementioned bottle cap with a lifting spout, the bottle cap body includes a main cap and a flip cap. The guide channel is provided on the main cap and passes through the main cap. One side of the flip cap is hinged to the main cap, and the other side is engaged with the main cap through a locking structure. The bottle cap body is also provided with a rotatable pull ring, which has a first rotation position. When the pull ring is in the first rotation position, the inner wall of the pull ring is aligned with the locking structure and can block the locking structure.

[0012] In the bottle cap with a lifting spout described above, the pull ring also has a second rotation position, and the pull ring is provided with a placement groove; when the pull ring is in the second rotation position, the opening of the placement groove faces upward, and the pull ring can cooperate with the flip cover to form a storage space.

[0013] In the aforementioned bottle cap with a lifting spout, the pull ring is rotatably connected to the main cap via a pivot, and the main cap is provided with a guide groove arranged circumferentially along the pivot. The guide groove is provided with a first positioning part and a second positioning part, and the pull ring is provided with a movable part that can be movably engaged in the guide groove. When the pull ring is in the first rotation position, the movable part abuts against the first positioning part and can restrict the pull ring from continuing to rotate in the original direction. When the pull ring is in the second rotation position, the movable part abuts against the second positioning part and can restrict the pull ring from continuing to rotate in the original direction.

[0014] In the bottle cap with a lifting nozzle described above, the pull ring has a third rotational position; when the pull ring is in the third rotational position, a gripping space is formed between the inner wall of the pull ring and the bottle cap body.

[0015] The technical solution adopted by this utility model to solve its technical problem is to also provide a drinking bottle, including a bottle body, on which the above-mentioned bottle cap with lifting spout is installed.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In this utility model, the inner wall of the guide channel is provided with a first limiting structure extending in the axial direction, and the outer wall of the suction nozzle structure is provided with an integrally formed first and second locking parts. The first and second locking parts are arranged at intervals along the axial direction of the suction nozzle structure, and a first gap is formed between them to accommodate the first limiting structure. The second locking part is configured to be able to elastically deform in the horizontal direction. This design abandons the traditional independent retaining ring. On the basis of simplifying the structure, it realizes bidirectional limiting of the suction nozzle's upward and downward strokes, effectively reducing the number of parts and assembly steps, and lowering production costs. On the other hand, it improves the convenience of disassembly, assembly, and maintenance of the suction nozzle structure by utilizing the elastic deformation of the second locking part.

[0018] 2. In this utility model, the nozzle structure includes a snap-fit ​​body, and a second snap-fit ​​part is vertically disposed on the outer wall of the snap-fit ​​body, with a second gap between the second snap-fit ​​part and the snap-fit ​​body that allows for inward elastic deformation. This design allows the second snap-fit ​​part to smoothly pass over the first limiting structure in the guide channel under the action of external force during nozzle assembly or disassembly, achieving rapid "snap-on" installation and non-destructive disassembly, greatly simplifying the production and maintenance process and improving operational efficiency.

[0019] 3. In this utility model, the bottle cap is equipped with a rotatable pull ring with a placement groove and multiple rotation positions: In the first rotation position, it can cover the locking structure to prevent accidental opening of the cap and improve sealing security; in the second rotation position, the placement groove on the pull ring faces upward and can cooperate with the cap to form a storage space, serving as a simple stand for electronic devices such as mobile phones and tablets; in the third rotation position, a gripping space is formed between the pull ring and the bottle cap, allowing fingers to easily insert and pull the cap or drinking bottle. This design expands the pull ring from a single lifting function into a multi-functional component integrating anti-accidental contact, storage support, and lifting, truly achieving "one item, multiple uses," significantly improving structural utilization, product added value, and user experience.

[0032] like Figures 1 to 4 As shown, in this embodiment, a bottle cap with a lifting spout includes:

[0033] The bottle cap body 100 has a guide channel 111 extending in a vertical direction, and the inner wall of the guide channel 111 has a first limiting structure 112 extending in the axial direction.

[0034] The suction nozzle structure 200 is vertically and flexibly inserted into the guide channel 111. The outer wall of the suction nozzle structure 200 is provided with an integrally formed first locking part 211 and a second locking part 212. The first locking part 211 and the second locking part 212 are arranged axially spaced along the suction nozzle structure 200, and a first gap 213 is formed between them to accommodate the first limiting structure 112. The second locking part 212 is configured to be elastically deformable in the horizontal direction. When the suction nozzle structure 200 rises to a first preset position, the second locking part 212 engages with the lower surface of the first limiting structure 112 and can limit the suction nozzle structure 200 from rising further. When the suction nozzle structure 200 descends to a second preset position, the first locking part 211 engages with the upper surface of the first limiting structure 112 and can limit the suction nozzle structure 200 from descending further. This design abandons the traditional independent retaining ring. On the one hand, it simplifies the structure and achieves bidirectional limiting of the upward and downward stroke of the nozzle, effectively reducing the number of parts and assembly steps and lowering production costs. On the other hand, it utilizes the elastic deformation of the second retaining part 212 to improve the ease of disassembly, assembly and maintenance of the nozzle structure 200.

[0035] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the bottle cap includes a bottle cap body 100 and a spout structure 200 that is vertically mounted on the bottle cap body 100. The bottle cap body 100 connects to the bottle body 500 and effectively seals the opening of the bottle body 500, ensuring the bottle's leak-proof performance when carried or not in use. The spout structure 200 is used for the user to drink liquid; it can move vertically relative to the bottle cap body 100 to allow for exposed drinking in use and concealed storage when not in use, balancing convenience and protection.

[0036] Furthermore, the bottle cap body 100 includes a main cap 110 and a flip cap 120. The main cap 110 serves as the structural support base, used to install the suction nozzle structure 200, and is connected to the bottle mouth of the bottle body 500 by means of threads or snaps to achieve a sealed encapsulation of the bottle body 500; the suction nozzle structure 200 passes through the main cap 110 and can slide up and down axially under the action of external force and elasticity, thereby adjusting its extension length or retracting it.

[0037] Furthermore, the main cap 110 is provided with a guide channel 111 extending vertically and penetrating through itself, for accommodating the nozzle structure 200 and guiding its lifting and lowering. Preferably, the guide channel 111 is located at the center of the main cap 110, penetrating the entire main cap 110, forming a straight channel perpendicular to the bottom surface of the cap. This guide channel 111 not only provides a stable installation path for the nozzle structure 200, but also provides precise guidance for the nozzle structure 200 during its rising and falling through its inner wall, ensuring the smoothness and accuracy of the nozzle's movement.

[0038] Furthermore, the inner wall of the guide channel 111 is provided with a first limiting structure 112 extending in the direction of its own axis, forming a physical barrier to limit the movement range of the nozzle structure 200. This design allows the nozzle structure 200 to stop rising when it rises to the first preset position (i.e., the upper limit position) because the second engaging part 212 contacts the lower surface of the first limiting structure 112; and when it descends to the second preset position (i.e., the lower limit position), the first engaging part 211 contacts the upper surface of the first limiting structure 112 to prevent excessive descent, thereby achieving effective control of the bidirectional stroke of the nozzle structure 200.

[0039] Preferably, the first limiting structure 112 is annular, arranged circumferentially along the inner wall of the guide channel 111, and extends horizontally towards its axis. This design ensures that the nozzle structure 200 maintains a consistent contact state with the limiting structure at any rotation angle. This not only increases the contact area between the first limiting structure 112 and the first and second locking portions 211, enhancing the stability and reliability of the limiting, but also, due to its symmetry, helps reduce the risk of wear or damage caused by local stress concentration, thus extending its service life.

[0040] Furthermore, the guide channel 111 is provided with a second limiting structure 113 extending along its inner wall toward the axis at one end away from the first engaging portion 211. Preferably, the second limiting structure 113 is located in the bottom region of the guide channel 111 (i.e., the end close to the interior of the bottle body 500), protruding from the inner wall of the channel toward the central axis. Its main function is to provide a stable mounting reference and limiting support surface for the nozzle reset component 215 (such as a compression spring, elastic arm, or other elastic element).

[0041] Furthermore, the second limiting structure 113 is arranged in a ring along the inner wall of the guide channel 111 to form a ring boss or multiple circumferentially spaced locking structures, and has at least one notch 114 for the second locking part 212 to pass through, so as to avoid the second locking part 212 from interfering with the nozzle structure 200 during the lifting and lowering process.

[0042] Furthermore, the flip cover 120 is rotatably connected to the main cover 110, enabling opening and closing relative to the main cover 110. In the closed state, the flip cover 120 covers the outlet end of the mouthpiece structure 200, preventing external dust and contaminants from entering the mouthpiece and improving drinking hygiene; in the open state, the flip cover 120 opens, exposing the mouthpiece structure 200, making it convenient for the user to drink.

[0043] Furthermore, one side of the flip cover 120 is hinged to the main cover 110, and the other side is engaged with the main cover 110 through the locking structure 300, so that the flip cover 120 can be reliably locked when closed, preventing accidental opening due to vibration or accidental contact, and further improving sealing reliability and safety of use.

[0044] Furthermore, the locking structure 300 includes a locking member 310 movably disposed on one side of the main cover 110, and a first locking portion 320 disposed on the flip cover 120. The locking member 310 has a second locking portion 311 that engages with the first locking portion 320, and the locking member 310 has a first moving position and a second moving position. When the locking member 310 moves to the first moving position (locked position), the second locking portion 311 engages with the first locking portion 320, restricting the flip cover 120 from rotating open. When the locking member 310 moves to the second moving position (unlocked position), the second locking portion 311 disengages from the first locking portion 320, allowing the flip cover 120 to rotate open. This design achieves the locking and unlocking operation of the flip cover 120 through the horizontal movement of the locking member 310, simplifying the user's operation steps and improving the convenience and reliability of use.

[0045] Preferably, the locking member 310 has a movable groove 312 for the first locking part 320 to engage and move, and a second locking part 311 is disposed within the movable groove 312 and is in the shape of a triangular boss. The first locking part 320 is arranged vertically and has a rectangular groove 321 that extends horizontally through it for the second locking part 311 to engage. The triangular boss-shaped design of the second locking part 311 not only provides a larger contact area and enhances the locking effect, but also allows the first locking part 320 to slide into the movable groove 312 along the slope during the closing process, achieving automatic locking.

[0046] Furthermore, a locking reset member 330 is provided between the locking member 310 and the main cover 110. This locking reset member 330 is a compression spring, horizontally arranged, with one end abutting against the main cover 110 and the other end abutting against the locking member 310. When the user applies external force to the locking member 310 (pressing the outer wall of the locking member 310), the locking member 310 moves towards the second moving position and gradually compresses the locking reset member 330. As the locking member 310 moves, the second locking part 311 disengages from the rectangular groove 321 of the first locking part 320. At this time, the flip cover 120 flips open under the reset pushing force of the suction nozzle structure 200. When the user releases the pressure applied to the locking member 310, the locking member 310 resets under the elastic force of the locking reset member 330, returning to the first moving position (locked position), ready for the next locking operation. When the user applies external force to the flip cover 120 (closing the flip cover 120 onto the main cover 110), the first locking part 320 gradually engages with the movable slot 312 and pushes the second locking part 311 until the second locking part 311 engages with the rectangular slot 321 of the first locking part 320. The two parts abut against each other to prevent the flip cover 120 from opening. This design ensures that the flip cover 120 can automatically lock during the closing process without additional manual operation, thus improving the user experience.

[0047] Furthermore, the bottle cap body 100 is also provided with a rotatable pull ring 400. The pull ring 400 has a U-shaped structure and has a first rotation position, a second rotation position, and a third rotation position. The pull ring 400 is also provided with a placement groove 410. When the pull ring 400 is in the first rotation position, the inner wall of the pull ring 400 is aligned with the locking member 310 of the locking structure 300 and can block the locking member 310, preventing the locking member 310 from being accidentally triggered due to accidental contact or external pressure. This avoids the flip cap 120 from being opened abnormally, effectively enhancing the sealing safety of the bottle cap, and is especially suitable for preventing accidental opening in children's water bottles or sports scenarios. When the pull ring 400 is in the second rotating position, the opening of the placement slot 410 faces upwards, and the pull ring 400 can cooperate with the flip cap 120 to form a storage space, serving as a simple stand for electronic devices such as mobile phones and tablets. This allows users to place the drinking bottle upright and support electronic devices simultaneously in outdoor, office, or home settings, achieving dual convenience for drinking and use, greatly expanding the product's additional functions. When the pull ring 400 is in the third rotating position, a gripping space is formed between the inner wall of the pull ring 400 and the bottle cap body 100, used for lifting the bottle cap or drinking bottle. This design expands the pull ring 400 from a single lifting function into a multi-functional component integrating anti-accidental touch, storage support, and lifting, truly achieving "one item, multiple uses," significantly improving structural utilization, product added value, and user experience.

[0048] Furthermore, to achieve precise positioning and stable holding of the pull ring 400 in each working position, the main cover 110 is provided with an annular guide groove 115 extending circumferentially along the rotating shaft 420. A first positioning part 116 and a second positioning part 117 are symmetrically arranged within the guide groove 115. The pull ring 400 is provided with a movable part 430 (such as a protruding post or ball bearing structure) that can be moved and engaged within the guide groove 115. When the pull ring 400 is in the first rotation position, the movable part 430 abuts against the first positioning part 116, restricting the pull ring 400 from continuing to rotate in its original direction, ensuring that the pull ring 400 is accurately aligned with the locking member 310 and reliably blocked. When the pull ring 400 is in the second rotation position, the movable part 430 abuts against the second positioning part 117, restricting the pull ring 400 from continuing to rotate in its original direction, allowing the pull ring 400 to stably remain in the support posture, ensuring that the placement groove 410 is in a suitable tilt angle, and improving support stability.

[0049] Preferably, the placement slots 410 are U-shaped and there are two of them, symmetrically arranged on the two cantilever arms of the pull ring 400, and the placement slots 410 are arranged at an angle. This design allows the user to insert one end of the electronic device into the placement slot 410 for positioning, while the other end naturally leans against the outer wall surface of the flip cap 120, thus forming a stable triangular support structure. It makes full use of the spatial relationship between the bottle cap body 100 and the pull ring 400, and can reliably fix the electronic device without additional support components.

[0050] In this embodiment, the spout structure 200 includes a snap-fit ​​body 210 and a straw 220. These can be an integrally molded structure or a fixedly connected assembly, used to achieve switching between multiple drinking modes.

[0051] Preferably, the snap-fit ​​body 210 is provided with two independent drinking ports: one is a direct drinking port, which allows users to directly pour drinking liquids, suitable for scenarios such as sports and quick hydration; the other is a drinking port of the straw 220, which is connected to the straw 220 and is used for drinking by sucking, especially suitable for use scenarios that require spill prevention, such as children, driving, or sitting at a desk.

[0052] Furthermore, the snap-fit ​​body 210 is vertically and movably inserted into the guide channel 111 on the main cover 110. Its outer wall is provided with an integrally formed first snap-fit ​​portion 211 and a second snap-fit ​​portion 212 arranged at intervals along the axial direction. The first snap-fit ​​portion 211 is located in the upper region of the snap-fit ​​body 210, and the second snap-fit ​​portion 212 is located in the lower region, forming a first gap 213 extending axially between them. This gap is used to accommodate the first limiting structure 112 located on the inner wall of the guide channel 111. By using an integral molding process to manufacture the first snap-fit ​​portion 211 and the second snap-fit ​​portion 212 with the snap-fit ​​body 210, the independent limiting ring that needs to be assembled separately in the traditional structure is eliminated, achieving an integrated design of the limiting function. This not only significantly reduces the number of parts and lowers material costs, but also avoids production defects such as improper assembly, detachment, or omission of the retaining ring, effectively simplifying the assembly process and improving product consistency and manufacturing efficiency.

[0053] Furthermore, when the nozzle structure 200 moves up and down, the first gap 213 allows the first limiting structure 112 to slide inside it, ensuring smooth movement and providing guiding space for the stroke of the nozzle structure 200. This design allows the second locking part 212 to abut against the lower surface of the first limiting structure 112 when the nozzle structure 200 rises to the first preset position, restricting its further upward movement; when it descends to the second preset position, the first locking part 211 abuts against the upper surface of the first limiting structure 112 to prevent excessive descent, thereby achieving bidirectional limiting control of the lifting stroke of the nozzle structure 200.

[0054] Furthermore, the first snap-fit ​​portion 211 is horizontally disposed on the outer wall of the snap-fit ​​body 210 and protrudes radially toward the inner wall of the guide channel 111. Preferably, the first snap-fit ​​portion 211 has a continuous annular boss structure, arranged circumferentially around the snap-fit ​​body 210. This design can evenly bear the contact pressure from the first limiting structure 112, avoid local stress concentration, and improve limiting stability and structural durability. At the same time, the annular design helps to improve the consistency of injection molding and the convenience of demolding, which is beneficial to mass production.

[0055] Preferably, a sealing ring 230 is provided between the first snap-fit ​​portion 211 and the first limiting structure 112. The sealing ring 230 can be embedded on the upper surface of the first snap-fit ​​portion 211 or the lower surface of the first limiting structure 112 to prevent liquid from leaking from the gap between the guide channel 111 and the nozzle structure 200, thereby significantly improving the leak-proof performance of the bottle cap.

[0056] Furthermore, the second latching portion 212 is vertically disposed on the outer wall of the latching body 210, and a second gap 214 is formed between the second latching portion 212 and the latching body 210. The second gap 214 is configured to allow the second latching portion 212 to elastically deform toward the latching body 210 when subjected to external force. Specifically, the second gap 214 opens outward from the root of the second latching portion 212, forming a clearance space that allows it to elastically deform inward (i.e. toward the latching body 210) when subjected to force. When the nozzle structure 200 is assembled into the guide channel 111 from top to bottom, the outer end face of the second locking part 212 first contacts the upper surface of the first limiting structure 112 and undergoes radial contraction deformation under its guidance. The second gap 214 is compressed accordingly, allowing the second locking part 212 to smoothly pass over the first limiting structure 112 and enter its lower position. After assembly, the second locking part 212 resets under the action of elastic restoring force, forming an abutment limit on the lower surface of the first limiting structure 112, achieving stable engagement. Similarly, during disassembly, a special tool can be used to gently press the outer wall of the end of the second locking part 212 away from the first locking part 211 from the outside, causing it to undergo inward elastic deformation, thereby detaching from the lower surface of the first limiting structure 112 and achieving non-destructive disassembly of the nozzle structure 200. This design supports repeated assembly and disassembly, facilitating users to regularly clean the inside of the nozzle, improving hygiene performance, and avoiding the cleaning blind spots caused by traditional threaded connections or press-in non-removable structures.

[0057] Furthermore, the second engaging portion 212 extends vertically from top to bottom, and the end of the second engaging portion 212 away from the first engaging portion 211 protrudes radially toward the inner wall of the guide channel 111. This protrusion serves as the main limiting contact surface, abutting against the lower surface of the first limiting structure 112 when the suction nozzle structure 200 rises to the first preset position, effectively preventing it from continuing to rise, preventing the suction nozzle from overextending or disengaging from the guide channel 111, and achieving reliable limiting of the upward stroke.

[0058] Furthermore, a vertically arranged nozzle reset component 215 is provided within the second gap 214. Preferably, the nozzle reset component 215 is a compression spring, sleeved on the outer wall of the locking body 210. One end of the spring abuts against the lower stepped surface of the locking body 210, and the other end abuts against the second limiting structure 113 within the guide channel 111, forming stable axial support. When the user closes the flip cover 120 onto the main cover 110, the inner wall of the flip cover 120 presses downward against the top of the nozzle structure 200, forcing the entire nozzle to descend along the guide channel 111. At this time, the nozzle reset component 215 is compressed and stores energy. When the user opens the flip cover 120 and releases the pressure on the nozzle, the nozzle reset component 215, under the action of elastic restoring force, pushes the nozzle structure 200 to automatically rise to the preset usage height, realizing the automatic pop-up reset function. This design improves the ease of operation; the user does not need to manually pull out the nozzle, and can use it immediately after opening the cover.

[0059] In addition, by embedding the nozzle reset component 215 in the second gap 214, the structural space between the snap-fit ​​body 210 and the second snap-fit ​​part 212 is fully utilized. There is no need to set up an additional spring cavity or external mounting structure, which helps to reduce the overall height of the bottle cap, realize the miniaturization and compact structure design of the product, and improve the efficiency of internal space utilization.

[0060] like Figures 1 to 5 As shown in the figure, this utility model embodiment also provides a drinking bottle. The drinking bottle includes a bottle body 500 and the aforementioned bottle cap, wherein the bottle body 500 and the main cap 110 are connected by threads.
