Description

Technical Field

[0001] This utility model belongs to the field of cup lid technology, and specifically refers to a cup lid structure and container. Background Technology

[0002] After the cup lid and cup are sealed together, the threaded connection and the friction of the sealing ring make it difficult for users to quickly open the lid. To solve this problem, existing products usually design the lid as a combination of a main lid and a secondary lid, allowing users to quickly open and close the spout by operating the secondary lid.

[0003] One common way the main and secondary covers are fitted together is by the secondary cover rotatably fitting onto the main cover. Rotating the secondary cover opens and closes the main cover's outlet. When open, the outlets of the main and secondary covers are opposite each other; when closed, they are misaligned. The drawback of this structure is that the rotatable fit can generate significant frictional resistance, making it inconvenient for users to operate the secondary cover. It also causes wear on the contact surfaces of the main and secondary covers, affecting the product's lifespan. Utility Model Content

Detailed Implementation

[0036] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0037] refer to Figures 1 to 14 As shown, a first embodiment of the present invention is illustrated, namely a cup lid structure 100, including a lid body 101, a button 102 and an elastic member 103; See Figure 15 The lid 101 can be used to seal the upper opening 201 of the cup 200 to form a closed water container. It has a vertically penetrating movable channel 1041 inside, which is connected to a through hole 1011 on the lower surface of the lid 101. The inner wall of the movable channel 1041 is provided with a limiting groove 1042, which is configured with a first limiting point a and a second limiting point b. Button 102 includes a connecting pipe 1021 (e.g., a sealing ring) that is dynamically sealed within the movable channel 1041. The circumferential surface of the connecting pipe 1021 is provided with a movable protrusion 1022 that is slidably fitted within the limiting groove 1042. The elastic element 103 is located below the button 102 and is used to pop up the button 102; See Figures 9 to 14 When button 102 is pressed, movable protrusion 1022 can move cyclically between the first limiting point a and the second limiting point b. When movable protrusion 1022 is at the first limiting point a and the second limiting point b, the lower end of the connecting tube 1021 is in the closed and open state, respectively. That is, when the connecting tube 1021 is in the closed state, it is not connected to the through hole 1011, and when the connecting tube 1021 is in the open state, it is connected to the through hole 1011.

[0038] Through the above solution, the first embodiment provides a limiting groove 1042 and a movable protrusion 1022 between the lid 101 and the button 102, and utilizes the elastic force provided by the elastic element 103 to guide the movable protrusion 1022 to cyclically move between the first limiting point a and the second limiting point b when the button 102 is pressed. This allows the connecting tube 1021 to cyclically switch between a closed state and an open state. When the connecting tube 1021 is in the open state, the user can drink water. In use, the user only needs to press the button 102 to switch the open and closed state of the cup lid structure 100. After the user releases their finger, the reset and movement of the button 102 are both provided by the elastic element 103. This can avoid the large friction caused by the relative rotation of the contact surface between the lid 101 and the button 102, and is easy to operate with one hand. It can be applied to cup lid structures 100 of any size.

[0039] The following shows the structural details of the first embodiment: The aforementioned limiting groove 1042 has an approximately "inverted heart" shaped structure, comprising a first guide groove 10421 and a second guide groove 10422 located on the left and right sides of the first limiting point a, and a third guide groove 10423 and a fourth guide groove 10424 located on the left and right sides of the second limiting point b; the first limiting point a is higher than the second limiting point b; the adjacent ends of the first guide groove 10421 and the second guide groove 10422 are connected, the upper side of the connection point constitutes the aforementioned first limiting point a, and the lower side of the connection point is offset from the first limiting point a (i.e., not collinear), and the farthest ends of the first guide groove 10421 and the second guide groove 10422 are both located on the first limiting point b. Below the height of limiting point a; the adjacent ends of the third guide groove 10423 and the fourth guide groove 10424 are connected, the upper side of the connection point forms the aforementioned second limiting point b, and the lower side of the connection point is offset from the second limiting point b (i.e., not collinear), and the far ends of the third guide groove 10423 and the fourth guide groove 10424 are both located below the height of the second limiting point b; the end of the first guide groove 10421 far from the first limiting point a is connected to the end of the third guide groove 10423 far from the second limiting point b, and the end of the second guide groove 10422 far from the first limiting point a is connected to the end of the fourth guide groove 10424 far from the second limiting point b. Thus, the limiting groove 1042 provides guidance for the movement of the movable protrusion 1022, allowing it to circulate between the first limiting point a and the second limiting point b, completing one full circle in the limiting ring groove 1042 with each cycle. (1) When the movable protrusion 1022 is at the first limit point a, after the button 102 is pressed, the movable protrusion 1022 will move along the lower slope of the second guide groove 10422 on the right side of the first limit point a to the lower end of the second guide groove 10422. At this time, after the user releases the button 102, the movable protrusion 1022 will move along the upper slope of the fourth guide groove 10424 to the second limit point b, and the cup lid will complete the action of switching to the open state. (2) When the movable protrusion 1022 is at the second limit point b, after the button 102 is pressed, the movable protrusion 1022 will move along the lower inclined surface of the third guide groove 10423 on the left side of the second limit point b to the lower end of the third guide groove 10423. At this time, after the user releases the button 102, the movable protrusion 1022 will move along the upper arc surface of the first guide groove 10421 to the first limit point a.

[0040] Furthermore, an arc-shaped fifth guide groove 10425 connects the ends of the first guide groove 10421 and the third guide groove 10423, and a straight sixth guide groove 10426 connects the ends of the second guide groove 10422 and the fourth guide groove 10424. This allows the movable protrusion 1022 to change direction more smoothly between the guide grooves.

[0041] Meanwhile, the upper wall of the first guide groove 10421 or the second guide groove 10422 is provided with a connecting groove 1043 that connects to the upper port of the movable channel 1041. This allows the movable protrusion 1022 to easily move into the limiting slide groove 1042 during button 102 assembly. Specifically, the connection point between the connecting groove 1043 and the first guide groove 10421 / second guide groove 10422 can be designed with a layered cross-section to prevent the movable protrusion 1022 from returning into the connecting groove 1043, thereby preventing the connecting tube 1021 from falling out of the movable channel 1041 in case of improper operation; the upper port of the connecting groove 1043 is flared, making it easier for the movable protrusion 1022 to enter the connecting channel 1043, requiring only approximate alignment during assembly.

[0042] In addition, limit grooves 1042 are provided on both sides of the inner wall of the aforementioned active channel 1041; correspondingly, movable protrusions 1022 are provided on both sides of the circumferential surface of the connecting pipe 1021. Through the two pairs of limit grooves 1042 and movable protrusions 1022, the force on both sides of the button 102 can be balanced, resulting in higher structural and functional stability.

[0043] To facilitate the processing and molding of components and cleaning during use, in the first embodiment, the aforementioned movable channel 1041 is independently molded within the mounting base 104; a mounting groove 1012 is provided within the cover 101, which communicates with the through hole 1011; the mounting base 104 is magnetically engaged within the mounting groove 1012. Since both the button 102 and the mounting base 104 are subjected to downward force during installation, the user's force will not affect the axial position of the mounting base 104, resulting in a highly stable structure. When cleaning is required, since the movable protrusion 1022 of the button 102 engages with the first limiting point a / second limiting point b of the mounting base 104, the button 102 can be directly pulled out to remove the mounting base 104 for cleaning, making operation convenient (when setting up a suction tube later, the suction tube can be directly pulled out to remove the button 102 and the mounting base 104).

[0044] Furthermore, the mounting base 104 is provided with a guide groove 1044, and a tubular portion 1045 is provided at the axis of the guide groove 1044. The movable channel 1041 is coaxially provided in the tubular portion 1045. The lower surface of the button 102 is provided with a guide ring 1023 coaxially provided with the connecting pipe 1021. The guide ring 1023 is dynamically and sealingly fitted to the inner wall of the guide groove 1044 (for example, using a sealing ring). The elastic element 103 is preferably a spring made of stainless steel, with its upper end embedded in the guide ring 1023 and its lower end sleeved on the circumferential surface of the tubular portion 1045.

[0045] Secondly, the lower end face of the aforementioned guide ring 1023 extends to form at least one latch 1024; the inner wall of the guide groove 1044 is provided with a latch groove 1046 for the latch 1024 to move and engage. The latch groove 1046 provides space for the hook of the latch 1024 to move axially and circumferentially. The engagement with the latch 1024 can limit the movement of the button 102 by a larger contact area, preventing the force on the button 102 (such as the elastic force of the elastic element 103) from being concentrated at the position of the movable protrusion 1022. This plays a role in distributing the force, improving structural stability and durability, and does not interfere with the function of the button 102.

[0046] Meanwhile, at least one first magnet 105 is embedded in the cover 101, and at least one second magnet 106 is embedded in the mounting base 104. The lower surface of the cover 101 is provided with a first recess 1013 for installing the first magnet 105. The lower end opening of the first recess 1013 is fitted with a sealing plug 107 to prevent moisture from entering the first recess 1013. The bottom of the guide groove 1044 is provided with a second recess 1047 for installing the second magnet 106. The side wall of the mounting groove 1012 is provided with a positioning flange 1014, and the circumferential surface of the mounting base 104 is provided with a positioning groove 1048 that matches the positioning flange 1014. The positioning flange 1014 is embedded in the positioning groove 1048 so that the first magnet 105 and the second magnet 106 are vertically aligned, which limits the installation direction of the mounting base 104 in the mounting groove 1012, ensuring that the first magnet 105 can be aligned with the second magnet 106, thereby ensuring the stability of the magnetic attraction function.

[0047] The upper end face of the aforementioned connecting pipe 1021 is configured as an open end, and its lower end face is configured as a closed end, with at least one side of the lower end face having a water outlet 1025; sealing rings 108 are fitted on both the upper and lower sides of the connecting pipe 1021 at the water outlet 1025, and the sealing rings 108 are elastically fitted on the sidewall of the through hole 1011; the lower end of the through hole 1011 is provided with a flared portion 1015, see [reference]. Figures 6 to 8 The solid line with arrows indicates the direction of water movement. When the sealing ring 108 moves to the height of the flared part 1015, it does not contact the side wall of the flared part 1015, thereby enabling the water passage 1025 to be in a conductive state.

[0048] Furthermore, the first embodiment also includes a straw 109 and a drainage tube 110; the straw 109 is connected to the upper end of the connecting tube 1021, and the drainage tube 110 is connected to the flared portion 1015. Thus, by providing the straw 109 and the drainage tube 110, users can drink water by sipping, making it more convenient. Of course, the straw 109 can also be integrally formed onto the button 102; compared to an integrally formed straw, a separate straw 109 can be made of a different material than the button 102, such as food-grade silicone, ensuring convenient drinking (the straw is bendable) and greater hygiene and cleanliness. Specifically, the lower end of the straw 109 is inserted into the upper end of the water outlet channel 1023 by an inverted snap, facilitating assembly and disassembly; the circumference of the flared portion 1015 is detachably connected to a connector 111 (e.g., a rotating snap-fit, a snap-fit ​​connection, etc.), and the upper end of the drainage tube 110 is inserted into the connector 111.

[0049] The cover 101 is provided with a vent 1016 parallel to the movable channel 1041. The vent 1016 is positioned opposite to the button 102, specifically opposite to the edge of the button 102. A piston assembly 112 is disposed within the vent 1016. When the movable protrusion 1022 is at the second limit point b, the button 102 presses down on the piston assembly 112 to open the vent 1016. See also... Figures 6 to 8 The dotted arrow in the image indicates that the vent 1016 is normally closed, preventing gas from flowing out and thus maintaining its temperature. When the user presses button 102, the vent 1016 opens, allowing the inside of the cup to connect with the atmosphere, making it easier to pour out the water. Specifically, the piston assembly 112 includes a piston rod 1121 that passes through the vent 1016, a sealing gasket 1122 that is fitted onto one end of the piston rod 1121 and movably seals the vent 1016, a connector 1123 that connects to the other end of the piston rod 1121, and a return spring 1124 that is fitted onto the piston rod 1121 and abuts against the connector 1123 to return the piston rod 1121 to the state of sealing the vent 1016.

[0050] A silicone ring 113 is fitted around the periphery of the cover 101 to optimize the tactile feel of the cover 101.

[0051] refer to Figure 15 The diagram illustrates a second embodiment of the present invention, namely a container comprising the aforementioned lid structure 100 and a cup 200; the lid 101 seals and covers the upper opening 201 of the cup 200. Specifically, the lid 101 and the upper opening 201 of the cup 200 can be connected by a threaded connection, and a sealing ring is used to enhance the sealing effect.

[0052] Since the second embodiment adopts all the technical means of the first embodiment, it can also achieve the same technical effect as the first embodiment.

[0053] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
