Description

Technical Field

[0001] This invention belongs to the field of cup lid technology, and in particular relates to a cup lid structure and container that can automatically vent and lock. Background Technology

[0002] Water cups are common water containers in people's daily lives. To meet people's different drinking needs, different types of water cups have emerged. Flip-top cups with straws are popular because they are easy to use and come with a straw. However, flip-top cups with straws have certain safety hazards. When the air pressure inside the cup is high, water vapor inside the cup will spray out from the spout the moment the lid is opened, which can easily cause burns and other safety accidents. In addition, when the cup is in a bag, it is easy to accidentally press the button and open the lid, which can lead to accidental leakage.

[0003] Existing technologies have disclosed some solutions to address the above problems, such as setting an active venting device on the top or side of the cup lid, which can activate the venting switch before opening the lid, thereby releasing pressure in advance; and setting a lock on the cup lid to prevent accidental button activation to open the lid. However, these new structures all require users to perform an extra step before or after drinking water, and if they forget to do so, there will still be problems of scalding and leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a cup lid structure that can automatically vent air and lock, in order to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a cup lid structure with automatic venting and self-locking features includes:

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0053] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0054] like Figure 1 The diagram shown illustrates a structure of an automatically venting, self-locking cup lid according to an embodiment of the present invention, comprising:

[0055] Connector 2, flip cover 1 is movably connected to connector 2, and nozzle 15 is connected to connector 2;

[0056] Button 3 is movably connected to the connecting body 2, and button 3 engages with flip cover 1;

[0057] The toggle switch 4 is movably installed in the slide groove opened on the flip cover 1. The toggle switch 4 cooperates with the connecting body 2 to lock the flip cover 1.

[0058] An exhaust assembly is installed in the connecting body 2 and corresponds to the toggle switch 4. When the toggle switch 4 is moved, it drives the exhaust assembly to move for exhausting air.

[0059] In one embodiment of the present invention, the automatic venting and self-locking cup lid structure addresses the problems of easy scalding by water vapor and accidental activation of the switch in the prior art of the spring-loaded cup. It is equipped with a toggle button 4 and a venting component. By using the cooperation between the toggle button 4 and the connecting body 2, the flip cover 1 can only be opened by pressing the button 3 after the toggle button 4 is moved, thus avoiding the problem of accidental activation of the switch and eliminating the need for additional locking operations. When the toggle button 4 moves, it drives the venting component to move down, so that the venting process can be completed when the lid is opened without the need for additional venting operations.

[0060] The flip cover 1 is hinged to the connecting body 2 via the flip cover pivot pin 13, and the button 3 is hinged to the connecting body 2 via the button pivot pin 14.

[0061] like Figure 5 , Figure 17 As shown, in a preferred embodiment of the present invention, the dial 4 is provided with:

[0062] The second latching part 401 cooperates with the first latching part 102 provided on the flip cover 1.

[0063] A boss 402 is provided, which cooperates with a groove 202 provided on the flip cover 1 to lock the flip cover 1.

[0064] The first protrusion 403 corresponds to the exhaust assembly. When the dial 4 is moved, the first protrusion 403 pushes the exhaust assembly downward for exhaust.

[0065] The dial 4 is movably mounted in the horizontal slide groove at the top of the flip cover 1 and slides horizontally relative to the flip cover 1. The dial 4 is provided with a second locking part 401, which cooperates with the first locking part 102 provided on the flip cover 1 to drive the dial 4 to lock with the flip cover 1, preventing the dial 4 from falling off. When a pushing force is applied to the dial 4, the boss 402 disengages from the groove 202 to complete the unlocking. At the same time, the first protrusion 403 drives the exhaust component to move down to complete the automatic exhaust.

[0066] like Figure 2 As shown, in another preferred embodiment of the present invention, a first elastic element 10 is provided between the dial 4 and the flip cover 1 to drive the dial 4 to reset.

[0067] When a pushing force is applied to the dial 4, the first elastic element 10 is compressed and deformed, and the restoring force of the first elastic element 10 drives the dial 4 to reset.

[0068] like Figure 3 , Figure 16As shown, in a preferred embodiment of the present invention, the exhaust assembly slides relative to the sleeve 201 disposed on the connecting body 2. The sleeve 201 has a vent hole 213 communicating with the connecting body 2. The exhaust assembly includes:

[0069] Upper fastener 5, which is connected to lower fastener 6;

[0070] The top rod 7 passes through the through hole 211 on the sleeve 201 and is connected to the lower fastener 6;

[0071] The first sealing element 8 is installed on the top rod 7 and is used to seal the through hole 211 and the vent hole 212 opened on the through hole 211.

[0072] The second elastic element 11 is connected between the lower fastener 6 and the sleeve 201 and is used to drive the exhaust assembly to reset. When the toggle button 4 drives the upper fastener 5 and the lower fastener 6 to move down, the top rod 7 drives the first sealing element 8 to separate from the through hole 211 and the vent hole 212. The through hole 211, the vent hole 212 and the vent hole 213 are connected for exhaust.

[0073] The exhaust assembly is movably connected to the connecting body 2, and the upper fastener 5 and the lower fastener 6 are fixedly connected (the upper fastener 5 and the lower fastener 6 can also be integrated into one structure). The top rod 7 passes through the bottom through hole 211 of the sleeve 201 from bottom to top and is engaged with the lower fastener 6. Several vent holes 212 are provided around the through hole 211. The bottom of the top rod 7 is fitted with a first sealing element 8, which is used to block the through hole 211 and the surrounding vent holes 212. A vent hole 213 connected to the upper end face of the connecting body 2 is also provided on one side of the sleeve 201. When the knob 4 moves the 5 and the lower fastener 6 downward, the top rod 7 is moved downward. The first sealing element 8 at the bottom of the top rod 7 separates from the through hole 211 and the vent hole 212, and the through hole 211 and the vent hole 212 can then connect with the vent hole 213 to complete the exhaust.

[0074] like Figure 4 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the sleeve 201 is provided with an anti-rotation rib 214 on its inner side. The anti-rotation rib 214 cooperates with the anti-rotation groove 501 provided on the outer side of the upper fastener 5 for axial positioning.

[0075] The inner circumference of the sleeve 201 is provided with an anti-rotation rib 214, and the outer circumference of the upper fastener 5 is provided with a corresponding anti-rotation groove 501. The two work together to provide axial positioning between the exhaust assembly and the sleeve 201.

[0076] like Figures 6 to 7As shown, in a preferred embodiment of the present invention, the upper fastener 5 is provided with a second protrusion 502, which corresponds to the first protrusion 403. A second inclined surface 521 is provided on one side of the second protrusion 502, which cooperates with the first inclined surface 431 on one side of the first protrusion 403. When the dial 4 is moved, the first inclined surface 431 on the dial 4 cooperates with the second inclined surface 521, thereby driving the exhaust assembly to move down.

[0077] The second protrusion 502 has a second limiting end face 522 on the other side, which cooperates with the first limiting end face 432 on the other side of the first protrusion 403.

[0078] When the knob 4 is turned, the exhaust assembly moves downward through the engagement of the inclined surfaces of the first protrusion 403 and the second protrusion 502 until the lower end face of the first protrusion 403 abuts against the top end face of the second protrusion 502, and the first limiting end face 432 abuts against the second limiting end face 522.

[0079] like Figure 11 As shown, in a preferred embodiment of the present invention, the button 3 is provided with a second engaging part 301, which engages with the first engaging part 101 provided on the flip cover 1. Pressing the button 3 causes the second engaging part 301 to disengage from the first engaging part 101.

[0080] A third elastic element 12 is provided between the button 3 and the connecting body 2 to drive the button 3 to reset.

[0081] When the toggle switch 4 is turned and the button 3 is pressed, the third elastic element 12 is compressed and deformed, the second engaging part 301 is disengaged from the first engaging part 101, the flip cover 1 is separated from the connecting body 2, and can be pushed outward with the help of the elasticity of the suction nozzle 15.

[0082] like Figure 1 As shown, in a preferred embodiment of the present invention, the connecting body 2 is provided with a second sealing element 9 inside.

[0083] The second sealing element 9 is used to improve the sealing performance of the connector 2 and prevent water leakage.

[0084] like Figure 18 The diagram shown is a structural diagram of a container provided in an embodiment of the present invention, including the above-mentioned cup lid structure that can automatically vent and lock.

[0085] like Figure 19 As shown, in a preferred embodiment of the present invention, the container includes:

[0086] The cup body 16 is movably connected to the cup lid structure;

[0087] A straw 17 is installed in the cup body 16 and connected to the mouthpiece 15;

[0088] The bottom pad 18 is installed on the flip cover 1.

[0089] The aforementioned lid structure can be applied to the cup body 16 to connect the straw 17 to the mouthpiece 15 for easy drinking, and the bottom pad 18 improves the wear resistance of the bottom of the cup body 16.

[0090] like Figures 8 to 10 The diagram shown illustrates the structure of the cup lid from locking to opening. Figures 11 to 15 The diagram shows five states of the cup lid: locked, venting, unlocked, open, and fully open. The specific opening process and principle are as follows:

[0091] Initially, the flip cover 1 is closed, and the exhaust channel is closed;

[0092] Before opening the lid, push the knob 4 forward. The boss 402 disengages from the groove 202. The first inclined surface 431 presses against the second inclined surface 521, causing the exhaust assembly to move downward until the lower end face of the first protrusion 403 touches the top end face of the second protrusion 502 and the first limiting end face 432 touches the second limiting end face 522. At this time, the knob 4 moves forward to the limit position. Release the knob, and the knob 4 will remain in this position. The flip lock of the knob 4 on the flip cover 1 is released. At the same time, the first sealing member 8 releases the blockage of the vent hole 212 and the through hole 211 and the circumferential gap of the top rod 7, connecting to the vent hole 213 to form an exhaust channel. The air pressure inside the cup is released.

[0093] Press button 3 again, and the flip cover 1 will flip open around the flip cover pivot pin 13 under the elastic force of the suction nozzle 15. At the same time, the dial 4 will reset backward under the action of the first elastic element 10. (Because the dial 4 flips together with the flip cover 1, the boss 402 and the groove 202 are misaligned, so the boss 402 will not enter the groove 202 as the dial 4 resets.) Thus, as the flip cover 1 is fully opened, the dial 4 is also fully reset.

[0094] When the cover is closed, the protrusion 402 of the knob 4 abuts against the connecting body 2, forcing the knob 4 to slide forward slightly. Since the knob 4 slides forward slightly, the first inclined surface 431 of the knob 4 keeps pressing against the second inclined surface 521, and the exhaust assembly moves downward slightly, but is not restricted, until the cover 1 is completely closed. At this time, the exhaust assembly is reset, the exhaust passage is closed, the knob 4 is reset again, the protrusion 402 engages with the groove 202 again, and the cover 1 is locked again.

[0095] In summary, this cup lid structure requires unlocking before opening, and venting occurs simultaneously with unlocking. After venting and depressurization, the lid can be opened, and it automatically locks after closing. This self-locking mechanism effectively solves the problem of water leakage caused by accidental opening due to forgetting to lock the lid. The self-locking mechanism ensures that the lid must be unlocked every time it is opened, and venting occurs simultaneously with unlocking. This effectively solves the problem of water vapor splashing out of the cup the moment the spout is opened if the lid is opened without venting. This creates a fixed automatic cycle of unlocking, venting, and locking.

[0096] Meanwhile, since unlocking and venting are independent operations before the button is triggered to open the cover, there is sufficient time difference to fully vent the air.

[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
