Description

Technical Field

[0001] This utility model relates to drinking appliances, and more particularly to a dual-button cup lid and cup with phased unlocking. Background Technology

[0002] Existing flip-top water cups with sliding locks can only lock one button, making them unsuitable for cups with double-button lids. For cups with both a drinking spout and a sippy spout, the double-button lid typically includes a connecting body, a lower flip-top mounted on the connecting body, and an upper flip-top mounted on the lower flip-top. The drinking spout is located on the connecting body, and the sippy spout is located on the lower flip-top. The upper flip-top closes the sippy spout, and the lower flip-top closes the drinking spout. The opening and closing of the upper and lower flip-tops are generally controlled by buttons; pressing a button opens the corresponding flip-top. Locking both flip-tops typically uses a locking ring hinged to the connecting body. Flipping the locking ring upwards locks it onto the upper flip-top, locking both flip-tops simultaneously and preventing accidental button presses from opening them. However, this design can only lock both flip-tops at a time; it cannot lock a single flip-top individually. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-button cup lid and cup with a stroke-based unlocking mechanism, which locks the two buttons by a sliding latch that slides circumferentially.

[0004] This utility model is achieved through the following technical solution:

[0005] A dual-button cup lid with phased-stroke unlocking includes a connecting body, a lower flip-top, and an upper flip-top. The connecting body is detachably connected to the cup body. The rear end of the lower flip-top is rotatably mounted on the connecting body, and the rear end of the upper flip-top is rotatably mounted on the lower flip-top.

[0006] The front side of the lower flip cover is provided with an upper button that can slide in the front-back direction. Under the elastic force of the first elastic element, the upper button is at the front limit position, and the upper flip cover and the lower flip cover are fastened together by the upper button. The front side of the connecting body is provided with a lower button that can slide in the front-back direction. Under the elastic force of the second elastic element, the lower button is at the front limit position, and the lower flip cover and the connecting body are fastened together by the lower button.

[0007] The lower flip cover is equipped with a sliding latch that can slide, and the lower flip cover is equipped with a circumferential slide for the sliding latch to slide circumferentially. By controlling the position of the sliding latch in the circumferential slide, the two buttons can be fully locked, locked and unlocked at the same time, or fully unlocked when pressed backward.

[0008] As a preferred embodiment of the above-mentioned dual-button cup lid, the front side of the lower flip cover has an upper sliding groove for sliding the upper button. The rear side of the upper sliding groove is connected to the circumferential slide. The front side of the sliding latch has an upper limit protrusion that extends into the upper sliding groove. The rear side of the upper button has an upper limit post. By the upper limit protrusion corresponding to or offset from the upper limit post, the upper button can be locked or unlocked.

[0009] As a preferred embodiment of the aforementioned dual-button cup lid, the bottom of the sliding latch is provided with a downwardly extending latching part, and the front side of the connecting body has a sliding groove for slidingly installing the lower button.

A lower limit post is provided on the rear side of the lower button. By having the latching part correspond to or be offset from the lower limit post, the lower button can be locked or unlocked.

[0010] As a preferred embodiment of the aforementioned dual-button cup lid, the latching part of the sliding lock engages with the lower locking part of the lower button of the connecting body to achieve the fastening of the lower flip cover and the connecting body.

[0011] As a preferred embodiment of the above-mentioned dual-button cup lid, the outer side of the lower flip cover has a strip-shaped operating groove extending circumferentially, and the operating protrusion on the outer side of the sliding latch extends out of the lower flip cover from the strip-shaped operating groove. Moving the operating protrusion causes the sliding latch to slide circumferentially in the circumferential slide track.

[0012] As a preferred embodiment of the aforementioned dual-button cup lid, the sliding latch has a cantilevered elastic positioning section at one end along the circumferential direction. The outer side of the elastic positioning section has a recessed first positioning groove and a second positioning groove. The circumferential slide sidewall of the lower cover has a positioning protrusion. When the sliding latch is in the first circumferential position, the first positioning groove of the sliding latch cooperates with the positioning protrusion of the lower cover, and the sliding latch simultaneously blocks the rear sides of the upper and lower buttons at the front limit position, realizing full locking of the upper and lower buttons when pressed backward. When the sliding latch is in the second circumferential position, the second positioning groove of the sliding latch cooperates with the positioning protrusion of the lower cover, and the sliding latch disengages from the rear sides of the upper and lower buttons at the front limit position, realizing full unlocking of the upper and lower buttons when pressed backward.

[0013] As a preferred embodiment of the above-mentioned double-button cup lid, the outer side of the elastic positioning section of the sliding latch has a middle positioning groove, which is located between the first positioning groove and the second positioning groove. When the middle positioning groove of the sliding latch cooperates with the positioning protrusion of the lower flip cover, the upper limit protrusion is offset from the upper limit post, and the buckle part corresponds to the lower limit post.

[0014] As a preferred embodiment of the aforementioned dual-button cup lid, the flip-down cover is composed of an inner cover and an outer cover that are interlocked, and the circumferential slide is formed by the inner cover and the outer cover.

[0015] As a preferred embodiment of the aforementioned dual-button cup lid, the first drinking port located on the connecting body is sealed by the lower flip-top, and the second drinking port located on the lower flip-top is sealed by the upper flip-top.

[0016] This utility model also discloses a water cup, including a cup body and a cup lid, wherein the cup lid is a dual-button cup lid with a phased unlocking mechanism as described above.

[0017] This invention has the following advantages over the prior art:

[0031] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0032] See Figures 1 to 11 This embodiment discloses a water cup, including a cup body 1 and a cup lid, which is a dual-button cup lid with phased unlocking.

[0033] The dual-button cup lid includes a connecting body 2, a lower flip-top 3, and an upper flip-top 4. The connecting body 2 is detachably connected to the cup body 1 via a threaded connection. The rear end of the lower flip-top 3 is rotatably mounted on the connecting body 2, and the rear end of the upper flip-top 4 is rotatably mounted on the lower flip-top 3. The lower flip-top 3 seals the first drinking spout located on the connecting body 2, and the upper flip-top 4 seals the second drinking spout located on the lower flip-top 3. The first drinking spout is a direct drinking spout 5, and the second drinking spout is a sipping spout 6.

[0034] The front side of the lower flip cover 3 has an upper button 7 that can slide in the front-back direction. Under the elastic force of the first elastic element, the upper button 7 is at its front limit position. The upper flip cover 4 and the lower flip cover 3 are connected by the upper button 7. Specifically, the upper button 7's hook 8 engages with the upper flip cover 4's slot 9, thus connecting the upper and lower flip covers 3. The front side of the connecting body 2 has a lower button 10 that can slide in the front-back direction. Under the elastic force of the second elastic element 11, the lower button 10 is at its front limit position. The lower button 10 is connected by the lower flip cover 3 and the connecting body 2.

[0035] The lower cover 3 has a sliding latch 12 that can slide around the circumference of the lower cover 3. The lower cover 3 also has a circumferential slide 13 for the sliding latch 12 to slide around the circumference. By controlling the position of the sliding latch 12 in the circumferential slide 13, the two buttons can be fully locked, locked and unlocked when pressed backward, and fully unlocked.

[0036] The lower flip cover 3 consists of an inner cover 14 and an outer cover 15 that engage with each other. The inner cover 14 and the outer cover 15 are engaged by four evenly spaced circumferentially spaced protrusions 16 and four circumferentially spaced grooves 17. The circumferential slide 13 is formed by the inner cover 14 and the outer cover 15. The front side of the lower flip cover 3 has an upper sliding groove 18 for sliding the upper button 7. The rear side of the upper sliding groove 18 is connected to the circumferential slide 13. The front side of the sliding latch 12 has an upper limit protrusion 19 that extends into the upper sliding groove 18. The rear side of the upper button 7 has an upper limit post 20. The upper limit protrusion 19 and the upper limit post 20 correspond to or are offset from each other to lock or unlock the upper button 7. The lower cover 3 has a circumferentially extending strip-shaped operating groove 21 on its outer side. The operating protrusion 22 on the outer side of the sliding latch 12 extends out of the lower cover 3 from the strip-shaped operating groove 21. Moving the operating protrusion 22 causes the sliding latch 12 to slide circumferentially in the circumferential slide rail 13.

[0037] The sliding latch 12 has a downwardly extending latching part 23 at its bottom. The front side of the connecting body 2 has a sliding groove 24 for slidingly mounting the lower button 10. The latching part 23 of the sliding latch 12 extends downward through the lower flip cover 3 and into the sliding groove 24 of the connecting body 2. The lower button 10 has a lower limiting post 25 at its rear. The latching part 23 and the lower limiting post 25 correspond to or are offset from each other, thus locking or unlocking the lower button 10. The latching part 23 of the sliding latch 12 engages with the lower engaging part 26 of the lower button 10 of the connecting body 2, thus fastening the lower flip cover 3 to the connecting body 2. In this embodiment, the latching part 23 at the bottom of the sliding latch 12 serves both as a locking component for locking the lower button 10 and as a fastening component for fastening the lower button 10, providing dual functionality without the need for additional fastening components. This ingenious structural design...

[0038] The sliding latch 12 has a cantilevered elastic positioning section 27 at one end along the circumference. The elastic positioning section 27 has a recessed first positioning groove 28 and a second positioning groove 29 on its outer side. The side wall of the circumferential slide 13 of the lower flip cover 3 has a positioning protrusion 30. When the sliding latch 12 is in the first circumferential position, the first positioning groove 28 of the sliding latch 12 cooperates with the positioning protrusion 30 of the lower flip cover 3. The sliding latch 12 simultaneously blocks the rear sides of the upper and lower buttons in the front limit position, realizing full locking of the upper and lower buttons when pressed backward. When the sliding latch 12 is in the second circumferential position, the second positioning groove 29 of the sliding latch 12 cooperates with the positioning protrusion 30 of the lower flip cover 3. The sliding latch 12 disengages from the rear sides of the upper and lower buttons in the front limit position, realizing full unlocking of the upper and lower buttons when pressed backward. The sliding latch 12 has a middle positioning groove 31 on the outer side of the elastic positioning section 27. The middle positioning groove 31 is located between the first positioning groove 28 and the second positioning groove 29. When the middle positioning groove 31 of the sliding latch 12 cooperates with the positioning protrusion 30 of the lower flip cover 3, the sliding latch 12 is in the middle circumferential position. At this time, the upper limit protrusion 19 is offset from the upper limit post 20, and the latching part 23 corresponds to the lower limit post 25, realizing the locking and unlocking of the two buttons.

[0039] When the sliding latch 12 is in the first circumferential position, the first positioning groove 28 of the sliding latch 12 engages with the positioning protrusion 30 of the lower flip cover 3. The operation protrusion 22 of the sliding latch 12 is located at the left limit position of the strip operation groove 21 of the lower flip cover 3. At this time, the upper limit post 20 of the upper button 7 is blocked by the upper limit protrusion 19 of the sliding latch 12, and the lower limit post 25 of the lower button 10 is blocked by the latching part 23 of the sliding latch 12. Therefore, neither the upper button 7 nor the lower button 10 can be pressed backward, that is, both buttons are locked and the buttons cannot be pressed to open the two flip covers.

[0040] When the sliding latch 12 is in the second circumferential position, the second positioning groove 29 of the sliding latch 12 engages with the positioning protrusion 30 of the lower flip cover 3, and the operation protrusion 22 of the sliding latch 12 is located at the right limit position of the strip operation groove 21 of the lower flip cover 3. At this time, the upper limit protrusion 19 of the sliding latch 12 is offset from the upper limit post 20 of the upper button 7, and at the same time, the latching part 23 of the sliding latch 12 is offset from the lower limit post 25 of the lower button 10. Thus, both the upper button 7 and the lower button 10 can be pressed backward, that is, both buttons are unlocked, and either button can be pressed to open the corresponding flip cover.

[0041] When the sliding latch 12 is in the middle circumferential position, the middle positioning groove 31 of the sliding latch 12 engages with the positioning protrusion 30 of the lower flip cover 3, and the operation protrusion 22 of the sliding latch 12 is located in the middle of the strip operation groove 21 of the lower flip cover 3. At this time, the upper limit protrusion 19 of the sliding latch 12 is offset from the upper limit post 20 of the upper button 7, and only the lower limit post 25 of the lower button 10 is blocked by the latching part 23 of the sliding latch 12. That is, only the lower button 10 is locked, while the upper button 7 is unlocked. At this time, the upper button 7 can be pressed to open the upper flip cover 4. This mode can be used when only the upper flip cover 4 needs to be opened. Since only the upper button 7 is unlocked and the lower button 10 is locked, the accidental opening of the lower flip cover 3 due to the accidental touch of the lower button 10 can be effectively avoided.

[0042] The dual-button cup lid and water cup provided in this embodiment utilize a sliding latch 12. Through ingenious structural design, it achieves simultaneous locking and unlocking of both buttons, as well as single-button unlocking. The upper button 7 or lower button 10 can be unlocked in stages, thereby unlocking the upper flip cover 4 or the lower flip cover 3, flexibly adapting to different usage needs. During operation, simply moving the operating protrusion 22 causes the sliding latch 12 to slide circumferentially. Three positioning grooves are provided on the elastic positioning section 27 of the sliding latch 12, which respectively engage with the positioning protrusion 30 of the lower flip cover 3, enabling quick and accurate positioning of the sliding latch 12 in three circumferential positions, ensuring convenient operation, flexibility, and accuracy of the moving position.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
