Description

Technical Field

[0001] This utility model relates to the technical field of sealing drinking containers, and in particular to a splash-proof, spring-loaded straw cup lid. Background Technology

[0002] A common safety issue with straw cup lids is that when the cup is filled with hot water and the lid is sealed, the straw passage is blocked. Shaking the cup at this time will generate a large amount of steam. When the lid is opened, the straw passage is opened, and the steam pressure will force the hot water out of the straw at high speed, causing a scalding accident.

[0003] Existing straw cup lids generally have anti-splash structures, mainly in two ways: One is a direct temperature control valve, which keeps the valve closed when the temperature exceeds a set point (e.g., 55 degrees Celsius), preventing users from drinking directly from the straw. The straw can only be opened when the water temperature is below the set point, thus preventing scalding. While this solves the scalding problem, it doesn't completely prevent hot water splashing. Water at 50 degrees Celsius will still generate a lot of steam when shaken, and splashing is still unavoidable after opening the lid. The second method uses a venting and pressure-relieving structure. However, this structure doesn't fully open the lid when pressing; it only opens completely after releasing the pressure. This operation doesn't align with users' habits when using regular water cups, so the operation needs improvement to meet the needs of most users. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pop-up straw cup lid with pressure relief and anti-spray function.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a splash-proof, spring-loaded straw cup lid, including a bottom cover; a pressure relief component disposed on the top wall of the bottom cover, the pressure relief component having an exhaust channel; a sealing component slidably disposed on the bottom cover, the sliding of the sealing component driving a sealing plate to press and seal or open the exhaust channel; a locking component, which can be driven by the sealing component and move inward and outward on the bottom cover; a top cover, one end of which is hinged to the bottom cover, the other end of which can be closed with the bottom cover by the engagement of a latch and a hook, the sliding of the locking component being used to drive the hook to disengage or engage the latch.

[0006] Preferably, the two ends of the exhaust spring are respectively positioned between the sealing component and the locking component.

[0007] Preferably, the two ends of the locking spring are respectively positioned between the locking component and the side wall of the bottom cover.

[0008] Preferably, the spring force of the exhaust spring is less than that of the locking spring, forming a two-stage pressing and resetting mechanism.

[0009] Preferably, the pressure relief component protrudes from the top wall of the bottom cover, the exhaust channel is L-shaped, the pressure relief outlet is in the horizontal direction along the movement of the sealing component, and the pressure relief inlet is in the vertical direction.

[0010] Preferably, an exhaust sealing ring is provided at the outlet position of the exhaust channel.

[0011] Preferably, the pressure relief outlet of the exhaust channel is in a vertical direction, and the sealing plate is horizontally covering the pressure relief outlet.

[0012] Preferably, the button is located on the outside of the sealing component, and is used to move the sealing component inward when pressed.

[0013] Preferably, the sealing component has a locking hole and a pin at its rear end, the pin being inserted into the pin hole for limitation, and the locking hole sliding relative to the pin.

[0014] Preferably, the sealing component is provided with a third sliding groove, which falls into the limiting block and is limited to slide.

[0015] The beneficial effects of this utility model are as follows: First, the double spring reset ensures precise and controllable action and guarantees structural stability; second, the single-press double-action method conforms to user habits, and the process of depressurizing first and then opening the cover is automatically completed during operation; third, in the horizontal outlet scheme, the sealing plate and the sealing ring are pressed together by the elastic plane, which has a sealing effect while the discharged hot air will not be directly sprayed onto the user's hands, thus ensuring good safety.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0030] Example 1

[0031] Traditional straw cup lids pose a scalding risk because the steam pressure upon opening the lid can easily cause hot water to spray out of the straw during the initial opening of the cup. Existing temperature control valve solutions only limit opening at high temperatures but do not address the issue of steam splashing at low temperatures; conventional pressure relief methods require a step-by-step operation (pressure relief before opening the lid), which contradicts the user's habit of opening the lid with one hand. This invention aims to provide an integrated structure that allows for simultaneous pressure relief and lid opening with a single press.

[0032] Reference Figure 1 The illustration shows a press-and-slide mechanism for the anti-splash pop-up straw cup lid in this embodiment, which includes a bottom cover 100, a pressure relief component 200, a sealing component 300, a locking component 400, and a top cover 500. The bottom cover 100 and the top cover 500 are closed by the locking component 400, the pressure relief component 200 passes through the bottom cover 100, and the sealing component 300 opens and seals the pressure relief component 200, thereby achieving the function of pressure relief and anti-splash.

[0033] Specifically, the pressure relief component 200 has an exhaust channel 201 located on the top wall of the bottom cover 100. The sealing component 300 is slidably mounted on the bottom cover 100. The sliding of the sealing component 300 can cause the sealing plate 302 to press and seal or open the exhaust channel 201. The locking component 400 can be driven by the sealing component 300 and move in and out on the bottom cover 100. One end of the top cover 500 is hinged to the bottom cover 100, and the other end can be closed with the bottom cover 100 through the engagement of the latch 501 and the hook 402. The sliding of the locking component 400 is used to disengage the hook 402 or engage the latch 501.

[0034] As one implementation of the press-and-slide mechanism in this embodiment, button 305 is located on the outside of the blocking component 300 and is used to move the blocking component 300 inward after being pressed. At the same time, an exhaust spring 304 is provided between the blocking component 300 and the locking component 400, and a locking spring 404 is provided between the locking component 400 and the side wall 101 of the bottom cover 100. The elastic force of the exhaust spring 304 is less than that of the locking spring 404, thus forming a two-stage pressing and resetting mechanism.

[0035] Refer again Figure 1 It should be noted that the exhaust channel 201 shown in this embodiment is L-shaped, with its pressure relief outlet in the horizontal direction along the movement of 300 and its pressure relief inlet in the vertical direction. The outermost part of the sealing component 300 abuts against the button 305 via the exhaust spring 304. At the end of the sealing component 300 that moves inward, the sealing plate 302 presses tightly against the pressure relief inlet of the exhaust channel 201, creating a seal. As the sealing component 300 slides inward, the sealing plate 302 at its end opens the exhaust channel 201 to relieve pressure. After resetting outward, its end presses tightly against and seals the exhaust channel 201, thus achieving pressure relief and sealing. As a preferred embodiment for the sealing performance of the pressure relief port of the exhaust channel 201, an exhaust sealing ring 202 can be provided at the outlet position of the exhaust channel 201.

[0036] In one structural extension of this embodiment, the pressure relief outlet direction of the exhaust channel 201 can also be vertical (see reference). Figure 13 The exhaust channel 201 is a channel that runs vertically through the top surface of the bottom cover 100. An exhaust sealing ring 202 is provided at the outlet of the exhaust channel 201. The end of the sealing component 300, i.e., the sealing plate 302, is located above the pressure relief port of the exhaust channel 201. A sealing part, such as a downward protrusion, can be provided at the lower end corresponding to the outlet of the exhaust channel 201. By default (i.e., when the button 305 is released), the protrusion of the sealing component 300 just abuts against the exhaust sealing ring 202 and seals under the action of the exhaust spring 304.

[0037] Reference Figure 2-4The image below illustrates the changes in usage state of a pressing and sliding method as described in this embodiment. Figure 2 In the depressurization state, button 305 is pressed inward, sealing component 300 slides inward, and exhaust spring 304 is squeezed. At this time, sealing plate 302 disengages from exhaust passage 201, the passage opens and depressurizes. This state is the first stroke, and locking spring 404 is not compressed.

[0038] Reference Figure 3 Continue pressing button 305 inwards. The sealing component 300 continues to slide inwards, completing the second stroke. The sealing component 300, through the locking spring 404, presses the locking component 400 inwards. In this state, both the exhaust spring 304 and the locking spring 404 are compressed. After the locking component 400 slides inwards a certain distance, the locking hook 402 and the latch 501, which were originally in the engaged state, disengage until the top cover 500 can be opened. (Refer to...) Figure 4 The top cover 500 is open, and the sealing component 300 and locking component 400 are reset under the elastic force of the exhaust spring 304 and the locking spring 404.

[0039] Example 2

[0040] Reference Figure 5-13 As illustrated, this embodiment proposes another pressing and sliding method for the anti-splash bounce straw cup lid, namely, a combination of multi-level groove nesting sliding and double spring reset. The difference between this embodiment and the above embodiment is that the sealing component 300 includes a first groove 301 and a first reset plate 303, and the locking component 400 includes a second groove 401 and a second reset plate 403.

[0041] More specifically, the pressure relief component 200 protrudes from the upper surface of the bottom cover 100, and an exhaust channel 201 is provided inside the pressure relief component 200. The sealing component 300 slides on the pressure relief component 200 via the first sliding groove 301. The sliding of the sealing component 300 can drive the sealing plate 302 to press and seal or open the exhaust channel 201, thereby achieving pressure relief and sealing. The locking component 400 slides on the pressure relief component 200 via the second sliding groove 401 and is located below the sealing component 300. The sealing plate 302 slides within the second sliding groove 401. The top cover 500 can be closed with the bottom cover 100 by the engagement of the latch 501 and the hook 402. The sliding of the locking component 400 is used to disengage the hook 402 or engage the latch 501.

[0042] The bottom cover 100, pressure relief component 200, sealing component 300, locking component 400, and top cover 500 are linked together through nested sliding and elastic reset to form a two-stage pressing mechanism.

[0043] Reference Figure 7-8As illustrated, in one embodiment, to achieve the reset effect after pressing, the two ends of the exhaust spring 304 are respectively positioned between the first reset plate 303 and the second reset plate 403, and the two ends of the locking spring 404 are respectively positioned between the second reset plate 403 and the side wall 101 of the bottom cover 100. The elastic force of the exhaust spring 304 is less than that of the locking spring 404, forming a two-stage pressing and reset mechanism. The button 305 is located on the outside of the first reset plate 303 and is used to move the first reset plate 303 inward after pressing.

[0044] To better limit the relative sliding between the blocking component 300 and the locking component 400, a locking hole 306 and a pin 307 are provided at the rear end of the blocking component 300. The pin 307 is inserted into the pin hole 102 for limitation, and the locking hole 306 slides relative to the pin 307. The blocking component 300 also has a third sliding groove 308, which falls into the limiting block 405 and is limited in its sliding motion.

[0045] Reference Figure 9 As illustrated, in one embodiment, to achieve better sealing and ensure safety, the exhaust channel 201 is L-shaped, with its pressure relief outlet in a horizontal direction along the sealing component 300 and its pressure relief inlet in a vertical direction. An exhaust sealing ring 202 is provided at the outlet position of the exhaust channel 201.

[0046] Furthermore, in one structural extension scheme of this embodiment, referring to... Figure 13 In the middle, the pressure relief outlet direction of the exhaust channel 201 is vertical, that is, the channel that runs through the top surface of the bottom cover 100. An exhaust sealing ring 202 is provided at the outlet position of the exhaust channel 201. The lower end of the sealing component 300 can be provided with a sealing part corresponding to the outlet of the exhaust channel 201, such as a downward protrusion. By default (that is, when the button 305 is released), the protrusion of the sealing component 300 just abuts against the exhaust sealing ring 202 under the action of the exhaust spring 304 to seal.

[0047] In contrast, in the embodiment where the sealing plate 302 is horizontally fitted over the pressure relief outlet, but the exhaust channel 201 is L-shaped, the outlet of the exhaust channel 201 is horizontally positioned. This facilitates the contact between the sealing component 300 and the sealing ring under the action of the spring's restoring force, ensuring a better seal compared to the embodiment where the exhaust channel 201 is vertical. Furthermore, the L-shaped arrangement of the exhaust channel 201 allows for a smoother outward release of air pressure during pressure relief; and its orientation away from the button 305 means that the exhausted hot air will not directly spray onto the user's hand, making it safer.

[0048] Therefore, in this embodiment, the opening and closing mechanism, when the button 305 is pressed inward, firstly activates the sealing component 300 to open the exhaust passage 201 to release pressure, and only when the button 305 is pressed inward will the locking component 400 be triggered to open the top cover 500. This opening and closing mechanism only requires pressing the button 305 inward to complete the actions of venting and opening the cover, which is very much in line with the user's existing usage habits.

[0049] Of course, the anti-splash bounce straw cup lid of this embodiment also includes a spout 600, an upper pressure plate 700 and a lower pressure plate 800. The bottom cover 100 is provided with at least a water outlet channel and an air vent channel 201. The spout 600 is connected to the water outlet channel, and the straw can be connected to the lower end of the water outlet channel or the lower end of the spout 600.

[0050] The locking component 400 engages with the latches (locking buckle 501 and locking hook 402) on the top cover 500 to lock and close the top cover 500 and the bottom cover 100. When locked and closed, the upper pressure plate 700 on the top cover 500 and the lower pressure plate 800 on the bottom cover 100 together squeeze and seal the mouthpiece 600. The sealing component 300 is used to open and close the exhaust passage 201. First, the sealing component 300 moves to open the exhaust passage 201 to release pressure; with continued pressing, the locking component 400 moves again to separate from the latches, and the top cover 500 can then spring up and flip open under the action of the mouthpiece 600 and / or the torsion spring, exposing the mouthpiece 600 so that water can be drunk through the mouthpiece 600.

[0051] Reference Figure 9-12 The diagram illustrates the operation process of the cup lid in this embodiment:

[0052] Button 305 is integrally connected with sealing component 300. Button 305 is exposed on the side of the front end of bottom cover 100. An exhaust spring 304 is provided between sealing component 300 and locking component 400, and a locking spring 404 is provided between locking component 400 and bottom cover 100. The elastic force of locking spring 404 is greater than that of exhaust spring 304.

[0053] Refer again Figure 9 In the initial state, when button 305 is released, the sealing component 300, under the action of the exhaust spring 304, has its sealing plate 302 abutting against the exhaust sealing ring 202 to seal. Then, when button 305 is pressed, the button compresses the exhaust spring 304, causing it to move inward. At this time, the locking spring 404 remains stationary, and the sealing component 300 moves inward, opening the exhaust passage 201 to release pressure (this state is referenced). Figure 10 Continue pressing button 305 inward. After the blocking component 300 contacts the locking component 400, it pushes the locking component 400 inward, compressing the locking spring 404. At this time, the locking component 400 is in the disengaged state (refer to...). Figure 11 After that, the top cover can be opened (refer to this state). Figure 12).

[0054] To explain in more detail the principle and operation of the anti-splash cup lid in this embodiment:

[0055] The overall assembly structure includes a hierarchical nested structure, a pressure relief subsystem structure, a cover opening and locking subsystem structure, a double spring reset mechanism, and a stroke control mechanism, which are detailed below:

[0056] Hierarchical nested structure: The bottom cover 100 serves as the mounting base, and its inner side wall 101 is provided with an annular boss to support the pressure relief component 200; the pressure relief component 200 is a columnar boss; the first sliding groove 301 of the sealing component 300 is fitted onto the outer wall of the pressure relief component 200 to form a first-level sliding pair; the second sliding groove 401 of the locking component 400 is fitted onto the outer wall of the pressure relief component 200 and is located below the sealing component 300 to form a second-level sliding pair; the top cover 500 is hinged to the bottom cover 100 through a pivot, and its latch 501 and latch 402 form an opening and closing interface.

[0057] The pressure relief subsystem structure is as follows: the exhaust channel 201 passes through the L-shaped channel of the pressure relief component 200, the vertical inlet connects to the inner cavity of the cup, and the horizontal outlet faces away from the button 305; the horizontal outlet end face is fitted with an annular exhaust sealing ring 202, which can be made of elastic sealing material; the blocking component 300 is designed in a linkage manner, with the sealing plate 302 being a horizontally extending tongue, which normally covers the exhaust sealing ring 202 to form a surface seal; the first reset plate 303 is integrally formed with the button 305, and when pressed, it drives the blocking component 300 to slide as a whole; the pin limiting mechanism has a pin 307 inserted into the pin hole 102 of the bottom cover 100, and the locking hole 306 of the blocking component 300 slides outside the pin 307, limiting its horizontal displacement only.

[0058] The structure of the cover locking subsystem is as follows: the locking component 400, wherein the second reset plate 403 extends horizontally, and a locking spring 404 is provided between its lower surface and the side wall 101 of the bottom cover; the side wall is provided with an oblique locking hook 402, which forms a hook-and-loop engagement with the latch 501 of the top cover 500.

[0059] Stroke control mechanism: The bottom of the sealing component 300 is provided with a third slide groove 308, and the top of the locking component 400 is provided with a limiting block 405; the limiting block 405 is embedded in the third slide groove 308, and the two are in clearance fit: Initial state: the limiting block 405 abuts against the upper edge of the third slide groove 308; First-level pressing: the limiting block 405 moves along the third slide groove 308, and the two do not contact each other; Second-level pressing: the third slide groove 308 can push the limiting block 405 to move.

[0060] Dual-spring reset mechanism: an exhaust spring 304 is located between the first reset plate 303 and the second reset plate 403; a locking spring 404 is located between the second reset plate 403 and the bottom cover side wall 101; the mechanical relationship is that the critical force value that the exhaust spring 304 can be compressed is less than the initial compression resistance of the locking spring 404, thus forming a separation of actions.

[0061] In this embodiment, the pressure relief component 200 is a fixed axis; the sealing component 300 and the locking component 400 are sequentially sleeved to form a coaxial double slider mechanism. The pin 307 and the lock hole 306 are rigidly positioned to prevent the sealing component 300 from tilting and jamming; the length of the third slide groove 308 is equal to the first pressing stroke, ensuring that the cover opening is triggered only after the pressure relief is completed.

[0062] Furthermore, in one embodiment, alternatives to the elastic element can be used. For example, the exhaust spring 304 can be replaced with a silicone elastic post, and the locking spring 404 can be replaced with a leaf spring structure. The third slide groove 308 can be changed to a stepped groove, allowing the secondary pressing to be triggered by contacting the limiting block 405 via the stepped surface. A guide rib can be added between the pin 307 and the pin hole 102 to improve sliding stability.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
