Description

Technical Field

[0001] This utility model relates to the field of drinking cup technology, specifically to a screw-on insulated cup. Background Technology

[0002] Traditional insulated cups mostly feature a single flip-top lid, which not only easily allows dust to accumulate on the rim when opening and closing but also leaks frequently when carried. While push-button and spout lids emerged later, they had significant drawbacks. For example, some spout lids required manually lifting the spout, making it easy for fingers to touch and contaminate it; push-button lids were complex and inconvenient for drinking from different angles. Against this backdrop, the screw-on lid was developed and, thanks to its rotating opening and closing mechanism, gradually became the mainstream choice.

[0003] However, common screw-on cup lids usually rely on the user's own feel to turn them to the appropriate angle to open or close the spout. This can easily lead to the spout not being completely sealed due to insufficient turning, resulting in water leakage. Utility Model Content

Detailed Implementation

[0017] The specific implementation of the screw-type thermos cup provided by this utility model will be further described with reference to the accompanying drawings and embodiments.

[0018] like Figure 1As shown, a screw-on insulated cup includes a cup body 1, a bottom cover 2, a dust cover 3, and a limit reminder cover 4. The bottom cover 2 is threadedly connected to the cup body 1. The dust cover 3 is fastened to the top of the bottom cover 2 and rotatably connected to it. The limit reminder cover 4 is snapped into place at the middle of the top of the dust cover 3. To seal the water outlet of the insulated cup, a sealing mounting bracket 207 is provided at the bottom center of the bottom of the bottom cover 2. A sealing component 6 is detachably installed within the sealing mounting bracket 207; a sealing fixing seat 7 for fixing the sealing component 6 is slidably provided at the bottom of the sealing mounting bracket 207.

[0019] Preferably, in order to make it easier for users to intuitively determine whether the water outlet of the thermos is completely sealed, a sound lever 403 is provided on one side of the bottom of the limit reminder cover 4; a first baffle 204 and a second baffle 205 are provided on the top of the bottom cover 2 corresponding to the left and right sides of the sound lever 403.

[0020] like Figure 2 (a)- Figure 2 As shown in (c), the bottom cover 2 has a mounting hole in the center for mounting the dust cover 3 shaft; the top side of the bottom cover 2 has a water outlet 201 that communicates with the inner cavity of the cup body 1; the top side of the bottom cover 2 away from the water outlet 201 has an air hole 206 that communicates with the inner cavity of the cup body, so as to release the pressure inside the cup and prevent spraying and splashing.

[0021] To facilitate opening and closing the cover within a fixed turning angle, the top of the bottom cover 2 is also provided with a first rotation limiting plate 202 and a second rotation limiting plate 203. It is worth noting that the angle between the side of the first rotation limiting plate 202 away from the first baffle 204 and the side of the second rotation limiting plate 203 away from the second baffle 205 is 120°. Correspondingly, an anti-rotation block 306 is provided on the bottom of the dust cover 3 away from the paddle mounting opening 305. In use, the anti-rotation block 306 can rotate back and forth between the side of the first rotation limiting plate 202 away from the first baffle 204 and the side of the second rotation limiting plate 203 away from the second baffle 205, thus limiting the rotation angle of the dust cover 3 to 120°. Of course, this angle can be adjusted appropriately, and the specific rotation angle here should not be considered a further limitation of this utility model.

[0022] like Figure 3 (a)- Figure 3As shown in (b), the top of the dust cover 3 is provided with two first slots 303 and a paddle mounting port 305 at equal intervals; the paddle mounting port 305 corresponds to the position of the audio paddle 403 and the two first slots 303 are respectively located on both sides of the paddle mounting port 305. The top of the dust cover 3 is symmetrically provided with second slots 304 near the paddle mounting port 305. During installation, the audio paddle 403 at the bottom of the limit reminder cover 4 passes through the paddle mounting port 305 and extends downward to the top of the bottom cover 2. It is worth emphasizing that the bottom end face of the audio paddle 403 must be at least lower than the top end face of the first baffle 204, so that it can undergo elastic deformation and produce an audible prompt when it is moved back and forth with the first baffle 204.

[0023] Preferably, the dust cover 3 has an arc-shaped water outlet groove 301 on one side of its waist. When drinking water, the dust cover 3 is rotated so that the water outlet 201 is completely located in the middle of the arc-shaped water outlet groove 301. When closing the cover, the arc-shaped water outlet groove 301 needs to be rotated away from the water outlet 201.

[0024] Preferably, a rotating shaft 302 is provided at the bottom center of the dust cover 3, and a pressing block 3023 is provided at the bottom of the rotating shaft 302; an annular groove 3022 is provided on the side wall of the rotating shaft 302 near the pressing block 3023; and a driving block 3021 is also provided on the middle side of the rotating shaft 302 for sealing or releasing the water outlet 201 and the air hole 206 by the sealing component 6.

[0025] like Figure 4 (a)- Figure 4 As shown in (b), a fixing hook 401 is provided at the bottom of the limit reminder cover 4 corresponding to the position of the first slot 303, and the fixing hook 401 is engaged with the first slot 303; a side block 402 is provided at the bottom of the limit reminder cover 4 corresponding to the position of the second slot 304, and the side block 401 is engaged with the second slot 304, thereby realizing the fixation of the limit reminder cover 4 and the dust cover 3.

[0026] like Figure 5 (a)- Figure 5 As shown in (b), the sealing assembly 6 includes a sealing base 601 and a sealing slide 602. Specifically, the top of the sealing slide 602 is provided with an annular mounting groove 606 for mounting the sealing base 601; a return spring 603 is provided between the sealing base 601 and the inner wall of the sealing slide 602, and the sealing base 601 is movably connected to the annular mounting groove 606 of the sealing slide 602 through the return spring 603.

[0027] In order to limit the relative movement between the sealing base 601 and the sealing slide 602, a plurality of limiting hooks 6011 are symmetrically arranged on the outer side wall of the sealing base 601; the sealing slide 602 is provided with side sliding grooves 6021 along its height direction corresponding to the positions of the limiting hooks 6011, and the limiting hooks 6011 are slidably connected to the side sliding grooves 6021 at their corresponding positions.

[0028] Preferably, the outer wall of the sealing slide 602 is provided with a water outlet plug 604 corresponding to the position of the water outlet 201, and an air hole plug 605 is provided corresponding to the position of the air hole 206.

[0029] To limit the installation of the sealing assembly and ensure precise alignment with the outlet 201 and the vent 206, two first limiting grooves 2071 are symmetrically arranged on the inner side wall of the sealing mounting bracket 207; a limiting slider 6022 is provided on the outer side wall of the sealing slide block 602 corresponding to the position of the first limiting grooves 201, and the limiting slider 6022 of the sealing slide block 602 is slidably connected to the first limiting grooves 207 on the inner wall of the sealing mounting bracket 207 of the bottom cover 2.

[0030] To achieve simultaneous rotation of the dust cover 3 and up-and-down movement of the sealing assembly, thereby sealing the water outlet of the thermos, a wedge-shaped plate 6023 is provided in the middle of the inner wall of the sealing slide 602. Specifically, the wedge-shaped plate 6023 is an arc-shaped structure with the rotation center of the dust cover 3 as its center, and its bottom height (i.e., plate thickness) continuously varies along the circumference of the sealing slide 602. During the opening and closing of the cover, the rotating shaft 302 of the dust cover 3 passes downward through the mounting hole and the center position of the sealing slide 602, and the driving block 3021 on the side wall of the rotating shaft 302 can cooperate with the bottom end face of the wedge-shaped plate 6023.

[0031] like Figure 6 (a)- Figure 6 As shown in (b), a U-shaped through groove 701 is provided on one side of the sealing and fixing seat 7; a tapering protrusion 703 is symmetrically provided on the inner side wall of the U-shaped through groove 701 near its closed end. It is worth noting that the size of the area enclosed by the tapering protrusion 703 and the closed end of the U-shaped through groove 701 is adapted to the size of the annular groove 3022; an arc-shaped push-pull plate 702 is provided on the bottom side of the sealing and fixing seat 7 away from the opening of the U-shaped through groove 701 for easy disassembly and assembly by the user. During installation, the annular groove 3022 of the rotating shaft 302 slides into the U-shaped through groove 701 and is engaged in the area enclosed by the tapering protrusion 703 and the closed end of the U-shaped through groove 701. Then, the sealing and fixing seat 7 is pressed tightly against the bottom of the sealing mounting bracket 207 at the bottom of the bottom cover 2 by the clamping block 3023, so as to achieve the anti-detachment fixing of the sealing component in the sealing mounting bracket 207. Figure 7As shown. It is worth emphasizing here that the maximum inner diameter of the U-shaped through groove 701 is smaller than the outer diameter of the clamping block 3023.

[0032] More preferably, in order to improve the overall sealing performance of the thermos, a sealing ring is provided at the connection between the cup body 1 and the bottom cover 2; a silicone water-sealing ring (not shown in the figure) is provided between the rotating shaft 302 and the mounting hole.

[0033] For user convenience, a carrying handle 5 is provided on the outer side wall of the bottom cover 2.

[0034] More preferably, the top of the dust cover 3 is laser-engraved with a turning direction mark and a switch mark, which, together with the turning angle and sound prompts, can better assist users in using it easily.

[0035] When water is needed, the dust cover 3 is rotated 120° counterclockwise on the top of the bottom cover 2 towards the opening direction of the water outlet 201. The audio paddle 403 moves from the groove between the first baffle 204 and the second baffle 205 to the side closer to the first limiting plate 202. Its bottom is plucked with the first baffle 204 to emit the first prompt sound until the anti-rotation block 306 rotates to abut against the second limiting plate 203 and stops rotating. At the same time, the drive block 3021 of the rotating shaft 302 separates from the bottom end face of the wedge plate 6023. Under the tension of the return spring 603, the water sealing slide 602 moves downward, and the water outlet plugs 604 and air hole plugs 605 on both sides separate from the water outlet 201 and air hole 206. At this time, the water outlet 201 is fully opened, thus realizing water output. After drinking, rotate the dust cover 3 clockwise 120°. The audio paddle 403 will turn back to the side close to the second limiting plate 203. Its bottom will be paddled again with the first baffle 204 and emit a second prompt sound until the anti-rotation block 306 rotates back to abut against the first limiting plate 202 and stops rotating (at this time, the audio paddle 403 returns to the groove between the first baffle 204 and the second baffle 205). At the same time, as the dust cover 3 rotates, the bottom surface of the wedge plate 6023 of the water sealing slide 602 contacts the top surface of the drive block 3021. The wedge plate 6023 is pressed upward by the drive block 3021 and the return spring 603 is compressed until the water outlet plug 604 and the air hole plug 605 are pressed together with the water outlet 201 and the air hole 206 to complete the water outlet seal, and the cover is closed.

[0036] Compared to traditional screw-on thermos lids, this invention utilizes a dust cover to rotate a limit reminder cover, causing the bottom lever and the first stop plate to move back and forth, producing a "click" sound. Users can use this sound to determine if the spout is completely sealed, thus preventing leaks. In addition, all major components of this invention are detachable, making it convenient for users to clean and solving the problem that most thermos lids cannot be cleaned from all parts.
