Description

Technical Field

[0001] This utility model relates to the field of lid technology, and in particular to a spout water cup. Background Technology

[0002] A water cup, a common daily necessity, typically consists of a cup body and a lid. The lid prevents liquid from spilling. Usually, the lid has a drinking spout, allowing the liquid to flow out when the cup is tilted. To meet different user needs, cups with a spout attached to the lid have been invented, allowing users to sip liquid from the cup.

[0003] Chinese patent CN217510238U discloses a sliding-opening double-spring-loaded double-drinking cup lid, including a connecting body. The connecting body is characterized by having two drinking spouts and two flip-tops rotatably mounted on it, which seal the two drinking spouts respectively. The connecting body also has two sliding button assemblies, which elastically engage with the two flip-tops. Each sliding button assembly includes a sliding button and an elastic reset component. The connecting body has a sliding groove inside for the sliding button to slide back and forth. The sliding button and the elastic reset component are sequentially mounted on the sliding groove. In the groove, the outer side of the sliding button is provided with an operating protrusion, and the side wall of the connecting body is provided with a toggle groove for the operating protrusion to extend outward and slide back and forth. By toggling the operating protrusion, the sliding button is driven to move back and forth in the corresponding sliding groove. The sliding button is provided with a lower locking part, and each flip cover is provided with an upper locking part at the bottom. In the natural state, the elastic reset member elastically presses the sliding button against one end of the sliding groove. At this time, the lower locking part of the sliding button is engaged with the upper locking part of the corresponding flip cover. When the operating protrusion is toggled, the elastic reset member is compressed, and the lower locking part of the sliding button is disengaged from the upper locking part of the corresponding flip cover.

[0004] The aforementioned water cup with a spout requires the spout to be closed when not in use. This is achieved by a flip-top on the lid, which folds and bends to seal the spout. To drink, the flip-top must be opened first. In daily use, this design is not particularly convenient, as opening and closing it is somewhat cumbersome. Furthermore, the flip-top design increases costs and reduces the cup's usable volume. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a drinking cup with a spout. To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] A drinking cup with a spout includes a cup body and a cup lid. The top of the cup lid has a spout, and the cup lid has a recessed mounting groove. A movable component is installed in the mounting groove, and the outer end of the movable component is located on one side of the cup lid. The cup lid has a water inlet cavity that communicates with the spout. Pressing the outer end of the movable component opens or closes the water inlet cavity. The cup lid also has an air inlet groove that communicates with the mounting groove. An air return component is installed in the air inlet groove. The air return component is linked to the movable component, and the movable component drives the air return component to open or close the air inlet groove.

[0007] Furthermore, it also includes a housing fixed in the mounting groove, with an air inlet on the housing and a limiting part between the housing and the mounting groove; the movable component is installed laterally in the housing, and a return spring is provided in the housing to hold the movable component.

[0008] Furthermore, the movable component includes a support, a movable column at one end of the support that passes through the mounting groove and blocks the water inlet cavity, a block installed at the other end of the support, and a pressing block installed on the block and partially exposed on the outside of the housing. By pushing the pressing block, the block, support, and movable column are moved laterally to close the water inlet cavity. The diameter of the support is larger than that of the movable column and the block. The longitudinal movement of the air return component linked by the movement of the support opens or closes the air inlet groove.

[0009] Furthermore, the pressing block is provided with several ring-shaped locking blocks, the inner wall of the housing is provided with guide grooves for the locking blocks to move and locking parts for locking the locking blocks, and a rotation guide part is provided between the pressing block and the block body, so as to guide the pressing block to rotate and lock with the locking part.

[0010] Furthermore, the air return assembly includes a movable rod that moves longitudinally in the air inlet groove and partially extends out of the air inlet groove, a plug fitted on the lower end of the movable rod, and a locking block connected to the upper end of the movable rod. A return spring is provided inside the air inlet groove and supported at the bottom of the locking block.

[0011] Furthermore, the locking block is provided with a first arc-shaped block and a second arc-shaped block, which are located at the two ends of the locking block respectively, and a gap is formed between the first arc-shaped block and the second arc-shaped block; the movable component moves laterally to open the water inlet chamber, and at the same time the support pushes the first arc-shaped block to drive the air return component to move downward to open the air inlet slot. When the water inlet chamber is fully open, the support abuts against the first arc-shaped block, forming the normally open air return component; the movable component moves laterally to close the water inlet chamber, and at the same time, the support disengages from the first arc-shaped block and moves to the gap between the first arc-shaped block and the second arc-shaped block, and the return spring rebounds the air return component to close the air inlet slot.

[0012] Furthermore, a sealing ring is fitted onto the end of the movable column, and a first sealing rib and a second sealing rib are respectively provided at both ends of the sealing ring, and a third sealing rib is provided in the transverse direction between the first sealing rib and the second sealing rib.

[0013] Furthermore, the limiting part includes a slider on the outer wall of the housing and a groove in the mounting groove that is adapted to the slider. The limiting part also includes a buckle on the bottom of the housing and a slot on the mounting groove that is adapted to the buckle. The housing is installed into the mounting groove by sliding the slider in the groove to form a longitudinal limiting. After being fully installed, the buckle is engaged in the slot to form a lateral limiting.

[0014] Furthermore, the bottom of the water inlet chamber is provided with a suction tube mounting post that extends downward and communicates with the water inlet chamber, and the suction tube is inserted into the suction tube mounting post; a protective sleeve is provided on the nozzle.

[0015] Furthermore, the cup body is provided with a concave annular groove, and a mounting ring is provided on the annular groove. A handle assembly is installed on the mounting ring. The handle assembly includes a carabiner and a handle installed on one end of the carabiner. The two contacting ends of the mounting ring are provided with protruding extensions, and the two extensions are provided with corresponding holes through which the carabiner passes.

[0016] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0017] This invention features a cup lid with a recessed mounting groove containing a movable component. The lid has an inlet chamber connected to a spout. By manually pressing the movable component, the inlet chamber can be opened or closed. When open, water from inside the cup flows into the inlet chamber and is dispensed through the spout for drinking. When closed, water cannot be drunk from the cup through the spout. The operation is simple and convenient; it can be opened or closed with a single hand, ensuring a good user experience. Furthermore, the elimination of a top cover for sealing the spout saves materials and reduces production costs. The cup's height is reduced by the height of the flip-top, thus increasing the volume of liquid it can hold.

[0018] The cup lid has an air inlet slot connected to the mounting slot. The air inlet slot has a longitudinally movable air return component. The air return component is linked to the movable component. When the movable component opens the water inlet chamber, it drives the air return component to open. When the movable component closes the water inlet chamber, the user does not need to perform any additional operation to release air when drinking water, thus avoiding the situation where the internal liquid is sprayed out due to forgetting to release air when drinking water.

[0019] When the air return component is turned on, it is in a normally open state, ensuring that air can continuously enter. By staggering the air return component and the air intake slot, the opening is larger, and the air flow will not be obstructed, which helps to improve the air return efficiency, avoids the generation of negative pressure that may affect the user's drinking water, and helps the user drink water in large gulps.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7As shown, a sippy cup includes a cup body 1 and a cup lid 2. The top of the cup lid 1 has a protruding sippy spout 3 for drinking water from the cup body 1. The cup lid 2 has a recessed mounting groove 4, and a horizontally movable component 5 is provided in the mounting groove 4. The outer end of the movable component 5 protrudes from one side of the cup lid 2. The cup lid 1 has a water inlet cavity 6 that communicates with the sippy spout 3. By manually pressing the outer end of the movable component 5, the movable component 5 is activated to close or open the water inlet cavity 6. When open, water from inside the cup body 1 can flow into the water inlet cavity 6 and be drunk from the sippy spout 3. When closed, water from inside the cup body 1 cannot be drunk from the cup body 1 through the sippy spout 3. The operation is simple and convenient. It can be opened or closed with one hand, providing a good user experience. Furthermore, there is no need to use a flip-top to close the sippy spout, saving materials and reducing production costs. The height of the cup is reduced by the height of the flip-top, thus increasing the volume of liquid that the cup body can hold.

[0030] The cup lid 2 has an air inlet groove 37 connected to the mounting groove 4. The air inlet groove 37 is located below the mounting groove 4. The air inlet groove 37 has a longitudinally movable return air component 38, which is linked to the movable component 5. When the movable component 5 moves laterally, it drives the return air component 38 to open or close the air inlet groove 37. When the movable component 5 closes the water inlet cavity 6, the return air component 38 blocks the air inlet groove 37 to prevent liquid inside the cup body 1 from entering the air inlet groove 37. When the user pushes the movable component 5 to open the water inlet cavity 6, the movable component 5 simultaneously drives the return air component 38 to move longitudinally to open the air inlet groove 37. External gas can enter the cup body 1 through the air inlet groove 37 to balance the pressure difference between the inside and outside, ensuring that the user can drink continuously.

[0031] It also includes a housing 7 fixed within the mounting groove 4 for assembling the movable component 5. A limiting part 23 is provided between the housing 7 and the mounting groove 4 to restrict the movement of the housing 7. An air inlet 22 is provided on the housing 7, through which external gas enters the interior of the housing 7, and then enters the cup body 1 through the air inlet groove 37 to balance the pressure difference between the inside and outside. The movable component 5 is installed laterally within the housing 7. The movable component 5 moves towards one end of the water inlet cavity 6 to block the water inlet cavity 6, and moves in the opposite direction to disengage from the water inlet cavity 6, thus opening it.

[0032] The movable component 5 includes a support 9, a movable column 10 integrally formed at one end of the support 9 and passing through the mounting groove 4 to block the water inlet cavity 6, a block 11 fitted onto the other end of the support 8, and a pressing block 12 fitted onto the block 11 and partially exposed on the outside of the housing 7. The outer end of the movable component 5 is the pressing block 12. The block 11 is rotatably fitted onto the support 8. When the pressing block 12 is manually pressed, it pushes the block 11 and the movable column 10 to move laterally inward to close the water inlet cavity 6, and the pressing block 12 is locked to the housing 7. The housing 7 is provided with a return spring 8 that abuts against the movable component 5. The return spring 8 is fitted onto the movable column 10, with one end abutting against the support 9 and the other end abutting against the side wall of the mounting groove 4. Pressing the pressing block 12 again releases the lock between the pressing block 12 and the housing 7. After unlocking, the return force of the return spring 8 pushes the movable component 5 to move outward to open the water inlet cavity 6.

[0033] The pressing block 12 is provided with several ring-shaped locking blocks 13. The inner wall of the housing 7 is provided with a guide groove 14 and a locking part 15 adapted to the locking blocks 13. The guide groove 14 allows the locking blocks 13 to move laterally. The locking part 15 is located at the end of the guide groove 14 and allows the locking blocks 13 to be engaged to form a lock. After locking, the movable component 5 cannot be moved by the return force of the reset spring 8.

[0034] A rotation guide 16 is provided between the pressing block 12 and the block body 11. The rotation guide 16 is located on the side wall of the block body 11 and the end of the pressing block 12 near the block body. The rotation guide 16 consists of two mutually compatible annular inclined surfaces. When the pressing block 12 is pressed down, it gradually rotates through the inclined surfaces of the rotation guide 16.

[0035] When the water inlet chamber 6 is closed, press the pressing block 12 manually. The pressing block 12 drives the locking block 13 to move along the guide groove 14. When the displacement reaches a certain extent, the pressing block 12 and the block body 11 come into contact with each other. At this time, the locking block 13 disengages from the guide groove 14. Press the pressing block 12 continuously and rotate the guide part 16 to make the pressing block 12 rotate. At this time, the locking block 13 and the locking part 15 are in the same horizontal direction. After releasing, the return force of the reset spring 8 pushes the movable component 5, so that the locking block 13 engages with the locking part 15 to form a lock. At this time, the movable column 10 completely closes the water inlet chamber 6. There is space between the movable column 10 and the water inlet chamber 6 for the movable column 10 to continue to enter.

[0036] When the water inlet chamber 6 is opened, press the pressing block 12 manually to push the entire movable component 5 inward. The locking block 13 on the side wall of the pressing block 12 moves inward laterally to disengage from the locking part 15, and the locking state is released. The pressing block 12 is rotated by the guide part 16, so that the locking block 13 and the guide groove 14 are in the same horizontal direction. After releasing the hand, the restoring force of the return spring 8 pushes the movable component 5 outward laterally to open the water inlet chamber 6.

[0037] The length of the pressing block 12 exposed outside the cup 2 is greater than the distance between the pressing block 12 and the block body 11, ensuring that a part of the pressing block 12 is exposed outside the cup lid 2 after it is fully pressed down, so that the user can press it again to unlock.

[0038] This design closes the water inlet chamber 6 by pressing the movable component 5 and opens it by pressing the component 5 again. Traditionally, the water inlet chamber 6 is closed by pressing the movable component 5 and opened by pulling it out. Compared to the traditional approach, this design uses a pressing method to open and close the water inlet chamber 6, avoiding the movable component 5 being pressed too deeply into the lid 2, which would make it inconvenient to pull out, and also increasing its playability.

[0039] The return air assembly 38 includes a movable rod 39 that moves longitudinally within and partially extends out of the air intake groove 37, a plug 40 fitted onto the lower end of the movable rod 39, and a locking block 41 connected to the upper end of the movable rod 39. The movable rod 39 and the locking block 41 are integrally formed. The plug 40 includes a silicone sealing ring and is located below the air intake groove 37 to block it. A return spring 8 is installed inside the air intake groove 37 and supported at the bottom of the block 41. The return spring 8 is fitted onto the movable rod 39, with one end contacting the bottom of the air intake groove 37 and the other end contacting the block 41. After the return air assembly 38 moves downward to open the air intake groove 38, the return force of the return spring 8 pushes the return air assembly 38 upward to close the air intake groove 37.

[0040] The locking block 41 is provided with a first arc-shaped block 42 and a second arc-shaped block 43. The first arc-shaped block 42 and the second arc-shaped block 43 are respectively located at the two ends of the block 41, and a gap 21 is formed between the first arc-shaped block 42 and the second arc-shaped block 43.

[0041] When the water inlet chamber 6 is in a closed state, the air inlet slot 37 is also in a closed state. The support 9 is located in the gap 21 between the first arc block 42 and the second arc block 43, and the support 9 abuts against the return air assembly 38 from the top. When the press block 12 is pressed to open the water inlet chamber 6, the movable component 5 needs to move laterally inward to unlock. Therefore, the support 9 moves laterally inward while pushing the first arc-shaped block 42. The movable rod 39 moves downward gradually, and the plug 40 disengages from the bottom of the air inlet groove 37. Before the water inlet chamber 6 is opened, the air is vented to prevent the internal liquid temperature from being too high and causing it to spray out from the suction nozzle 3 when the water inlet chamber 6 is opened. After unlocking, the reset spring 8 pushes the movable component 5 to move laterally outward. The support 6 moves from the upper end of the first arc-shaped block 42 to the gap 21. The return air component 38 will be closed by the rebound force of the reset spring 8. The support 9 continues to move laterally outward to push the second arc-shaped block 43, causing the return air component 38 to move downward again to open the air inlet groove 37. When the water inlet chamber 6 is fully open, the support 9 is pressed against the upper part of the second arc-shaped block 43, realizing the normal opening of the return air component 38.

[0042] Traditional air return systems use silicone V-shaped valves or duckbill valves. Duckbill valves require negative pressure to deform and open the orifice for air inflow, and their small openings result in slow airflow, potentially affecting the smoothness of drinking. This design, however, uses a normally open air return component 38 to ensure continuous airflow. The larger opening prevents air resistance, improving air return efficiency and allowing for larger gulps of water. When the user opens the water inlet chamber 6 to drink, no additional air release is required, preventing the liquid from spraying out of the spout 3 if the water inside the cup body 1 becomes too hot and the water inlet chamber 6 is opened.

[0043] A sealing ring 17 is fitted onto the end of the movable column 9 to increase the sealing performance of the water inlet chamber 6 after it is closed. The sealing ring 17 has a first sealing rib 18 and a second sealing rib 19 on both ends, and a third sealing rib 20 on the side is provided between the first sealing rib 18 and the second sealing rib 19. The design of multiple sealing ribs further increases the water sealing performance of the sealing ring 17 and prevents internal liquid from overflowing and causing a bad user experience.

[0044] The limiting part 23 includes sliders 24 on both sides of the housing 7 and a groove 25 in the mounting groove 4 that is adapted to the sliders 24. The limiting part 23 also includes a buckle 26 at the bottom of the housing 7 and a groove 27 on the mounting groove 4 that is adapted to the buckle. When the housing 7 is assembled, it is inserted into the mounting groove 4 by sliding the sliders 24 in the grooves 24. When it is fully inserted, the buckle 26 is engaged in the groove 27. The assembly of the sliders 24 and the grooves 25 forms a longitudinal limiting, and the assembly of the buckles 26 and the grooves 27 forms a lateral limiting, which prevents the housing 7 from falling out of the mounting groove 4 during use and increases the connection strength of the various components of the product.

[0045] The bottom of the water inlet chamber 6 is provided with a straw mounting post 28 that extends downward and connects to the water inlet chamber 6. A straw 29 is inserted into the straw mounting post 28. The liquid in the cup body 1 enters the water inlet chamber 6 through the straw 29 and is finally dispensed for drinking through the spout 3.

[0046] The mouthpiece 3 is provided with a protective cover 30 to protect the mouthpiece 3 and prevent external dust from falling onto the mouthpiece 3 when not drinking.

[0047] The cup body 1 has a concave annular groove 31, and a mounting ring 32 is provided on the annular groove 31. The mounting ring 32 is used to install the handle assembly 33, making it convenient for users to grab the handle assembly 33 for carrying when going out. The handle assembly 33 includes a carabiner 34 and a handle 35 installed at one end of the carabiner 34. The two contacting ends of the mounting ring 32 have protruding extensions 36. The two extensions 36 fit together and have corresponding holes. The carabiner 34 passes through the holes for connection, and it is also convenient to disassemble when the handle assembly 33 and the mounting ring 32 are not in use.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
