Description

Technical Field

[0001] This utility model relates to the technical field of cup lids, and more particularly to a screwless handle lid. Background Technology

[0002] A threadless cap is a common accessory for water cups. Chinese patent CN216754140U discloses a threadless cup cap, which mainly includes a body, a sealing plate, an elastic seal, a flap, and a connecting rod. The elastic seal is sleeved on the body, the flap is hinged to the connecting rod, and the sealing plate is set on the connecting rod. When the flap is rotated downward, the flap drives the connecting rod to move upward in the vertical direction. The sealing plate moves upward with the connecting rod and squeezes the elastic seal, thereby causing the elastic seal to form a large-angle fold and press against the cup mouth to seal the cup mouth.

[0003] On the one hand, repeated opening and closing of the cup lid over a long period of time will cause the elastic seal to weaken, have a short service life, and not seal the cup opening tightly due to repeated folding of the elastic seal. On the other hand, when opening and closing the cup lid, the user needs to hold the cup body with one hand and flip the flap with the other hand, which makes opening and closing the cup lid inconvenient and needs to be improved. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies, such as the inconvenience of flipping and turning the screwless cap, the elastic sealing element relying solely on its own large-angle bending to seal the cup mouth resulting in fatigue after prolonged use, short service life, and incomplete sealing of the cup mouth. It provides a new screwless handle cap.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A threadless handle cover includes a cup lid, a flap, a connecting rod, an elastic seal, and a water-sealing plate. The cup lid has a receiving cavity and a handle located above the receiving cavity. The handle and the receiving cavity enclose a rotation space. The connecting rod is movably inserted into the cup lid, with its upper end protruding from the bottom of the receiving cavity. The flap is rotatably connected to the top of the connecting rod and rotates along the height direction within the rotation space. The flap drives the connecting rod and the water-sealing plate to move along the height direction. The water-sealing plate has a pushing slope that gradually slopes downward and outward along the height direction.

[0007] The cup lid, flap, connecting rod, and elastic seal are in a locked state and an open state. In the locked state, the flap is engaged with the cup lid, the connecting rod and the sealing plate move upward with the flap, the inner wall of the elastic seal contacts the pushing slope and gradually unfolds outward along the pushing slope, and the sealing plate pushes the elastic seal against the inner wall of the cup opening. In the open state, the flap rotates upward to face the handle and pushes the connecting rod downward, the sealing plate moves away from the elastic seal, and the elastic seal contracts and separates from the inner wall of the cup opening.

[0008] When the flap is turned downwards, the inner wall of the elastic seal contacts the inclined surface and expands outwards along the inclined surface. Thus, in the locked state, the elastic seal expands from the inside out and presses against the inner wall of the cup opening through the sealing plate. It no longer relies solely on the deformation of the elastic seal itself to press against the inner wall of the cup opening, thereby improving the sealing effect of the elastic seal on the cup opening in the locked state and extending the service life of the elastic seal. The handle provides a force point for the user's hand. When it is necessary to unlock the cup lid, one hand only needs to hold the handle to directly turn the flap upwards, improving the convenience of opening the cup lid. The rotation space formed by the handle and the cup lid can shield and protect the flap, reducing the possibility of accidentally touching the flap and causing it to rotate downwards when it is open.

[0009] Preferably, in the above-described threadless handle cover, the lower end of the elastic seal is coaxially provided with a limiting ring, and the side wall of the water sealing plate is provided with an annular groove. In the locked state, the lower end of the limiting ring is inserted into the annular groove and abuts against the bottom wall of the annular groove, and the upper end of the limiting ring is pressed against the inner wall of the cup opening.

[0010] The limiting ring not only strengthens the local thickness of the elastic seal, but also, in conjunction with the ring groove, allows the elastic seal to be pressed more tightly against the cup opening, further improving the tightness of the seal.

[0011] Preferably, in the above-described threadless handle cover, the upper surface of the cup cover is provided with a limiting groove communicating with the receiving cavity, the edge of the cup cover is provided with a clearance notch communicating with the limiting groove, and the end of the flap is provided with a protrusion. In the locked state, the flap is placed flat in the limiting groove, and the protrusion is located above the clearance notch and directly opposite the clearance notch.

[0012] The limiting groove restricts the flipper, and also allows the flipper to be embedded in the cup lid in the locked state, further preventing accidental activation of the flipper; the protrusion provides a contact point for the user's hand, and the clearance notch provides space for the user's hand, thus making it easier for the user to flip the flipper upwards.

[0013] Preferably, in the aforementioned threadless handle cover, the flap includes a horizontal plate and a connecting frame disposed on the lower surface of the horizontal plate. The connecting frame covers the upper end of the connecting rod and is rotatably connected. The connecting rod is provided with a pushing surface. In the locked state, the end of the connecting frame interferes with the bottom wall of the receiving cavity and restricts the flap from flipping upward. In the open state, the end of the horizontal plate rotates towards the pushing surface and pushes the connecting rod downward through the pushing surface. The end of the horizontal plate presses against the bottom wall and the pushing surface of the receiving cavity, forming interference to restrict the flap from flipping downward.

[0014] The flapper forms an interference fit with the bottom wall of the receiving cavity through the connecting frame, the cross plate, and the flapper itself, which restricts the flapper's rotation and improves the stability of the flapper in the open or locked state. Through the lever principle, when the flapper rotates upward, it will first drive the connecting rod to move downward slightly, which allows the inside of the cup lid to vent through the moving path of the connecting rod. Furthermore, the cooperation between the flapper and the pushing surface reduces the degree of resistance encountered when pushing the connecting rod downward.

[0015] Preferably, in the above-described threadless handle cover, the cup cover includes an upper cover and an inner plug. The handle is disposed on the upper surface of the upper cover, the elastic seal is disposed at the lower end of the inner plug, a protruding strip is disposed on the inner side wall of the upper cover, and an outwardly extending extension platform is disposed at the upper end of the inner plug. The extension platform is inserted between the protruding strip and the top inner wall of the upper cover for a mating fit.

[0016] The inner plug and the top cover are assembled through the cooperation of the extension platform and the convex strip, which has the advantages of simple structure and easy assembly; the cup lid is divided into a top cover and an inner plug for disassembly and installation, which facilitates modular production and assembly.

[0017] Preferably, in the above-described threadless handle cover, a positioning groove is provided on the side end of the extension platform, and a positioning block is provided on the inner side wall of the upper cover. The positioning block is inserted into the positioning groove and engaged. A vertical plate is provided on the inner plug, and the vertical plate abuts against the inner wall of the opening of the receiving cavity.

[0018] The horizontal positioning of the inner plug is limited by the insertion and engagement of the positioning groove and the positioning block, which further improves the stability of the inner plug when it is installed on the top cover. The installation angle of the inner plug can be positioned by the cooperation between the vertical plate and the receiving cavity. This not only prevents the inner plug from rotating when it is installed on the top cover, but also prevents the inner plug from rotating when the flap is rotated, which makes it convenient to use.

[0019] Preferably, in the aforementioned threadless handle cover, the flap protrudes upwards from the upper surface of the connecting frame to form a reinforcing rib, and the reinforcing rib has the same shape as the connecting frame.

[0020] By adding reinforcing ribs, the structural strength of the connecting frame and the forming part of the flip piece is enhanced, preventing the horizontal plate from deforming due to bending when the flip piece rotates. On the other hand, the connecting frame and the forming part of the horizontal plate can be covered and decorated, improving the aesthetics of the flip piece.

[0021] Preferably, in the aforementioned threadless handle cover, a return spring is sleeved on the outside of the connecting rod. One end of the return spring abuts against the bottom of the inner plug, and the other end of the return spring abuts against the upper surface of the water sealing plate. The return spring pushes the water sealing plate to move downward.

[0022] The return spring applies a downward force to the sealing plate, improving the smoothness of rotating the flap upwards and opening the cup lid.

[0023] Preferably, in the above-described threadless handle cover, the connecting rod has a rotating shaft, the outer surface of the rotating shaft is coaxially provided with abutting teeth, the connecting frame has a connecting hole, the rotating shaft is inserted into the connecting hole for insertion and engagement, and the abutting teeth abut against the inner wall of the connecting hole.

[0024] The abutting teeth enhance the tightness of the connection between the rotating shaft and the connecting hole, thereby improving the stability of the connection between the flap and the connecting rod. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0032] like Figures 1-5 As shown, a threadless handle cover includes a cup lid 1, a flap 2, a connecting rod 3, an elastic seal 4, and a water-sealing plate 5. The cup lid 1 has a receiving cavity 10, and a handle 6 is provided on the cup lid 1 above the receiving cavity 10. The handle 6 and the receiving cavity 10 enclose a rotation space 7. The connecting rod 3 is movably inserted into the cup lid 1, and the upper end of the connecting rod 3 extends out from the bottom of the receiving cavity 10. The flap 2 is rotatably connected to the top of the connecting rod 3 and rotates along the height direction within the rotation space 7. The flap 2 drives the connecting rod 3 and the water-sealing plate 5 to move along the height direction. The water-sealing plate 5 is provided with a pushing slope 51, which gradually slopes downward and outward along the height direction.

[0033] The cup lid 1, flap 2, connecting rod 3, and elastic seal 4 are in a locked state and an open state. In the locked state, the flap 2 is fastened to the cup lid 1, the connecting rod 3 and the sealing plate 5 move upward with the flap 2, the inner wall of the elastic seal 4 connects with the pushing slope 51 and gradually unfolds outward along the pushing slope 51, and the sealing plate 5 pushes the elastic seal 4 to press against the inner wall of the cup opening; in the open state, the flap 2 rotates upward to face the handle 6 and pushes the connecting rod 3 downward, the sealing plate 5 moves away from the elastic seal 4, and the elastic seal 4 contracts and separates from the inner wall of the cup opening.

[0034] Preferably, the lower end of the elastic seal 4 is coaxially provided with a limiting ring 41, and the side wall of the water sealing plate 5 is provided with an annular groove 52. In the locked state, the lower end of the limiting ring 41 is inserted into the annular groove 52 and abuts against the bottom wall of the annular groove 52, and the upper end of the limiting ring 41 is pressed against the inner wall of the cup opening.

[0035] Preferably, the upper surface of the cup lid 1 is provided with a limiting groove 11 communicating with the receiving cavity 10, and the edge of the cup lid 1 is provided with a clearance notch 12 communicating with the limiting groove 11. The end of the flip piece 2 is provided with a protrusion 21. In the locked state, the flip piece 2 is placed flat in the limiting groove 11, and the protrusion 21 is located above the clearance notch 12 and directly opposite the clearance notch 12.

[0036] Preferably, the flipper 2 includes a horizontal plate 22 and a connecting frame 23 disposed on the lower surface of the horizontal plate 22. The connecting frame 23 covers the upper end of the connecting rod 3 and is rotatably connected. The connecting rod 3 is provided with a pushing surface 31. In the locked state, the end of the connecting frame 23 interferes with the bottom wall of the receiving cavity 10 and restricts the flipper 2 from flipping upward. In the open state, the end of the horizontal plate 22 rotates towards the pushing surface 31 and pushes the connecting rod 3 downward through the pushing surface 31. The end of the horizontal plate 22 presses against the bottom wall of the receiving cavity 10 and the pushing surface 31, and forms interference to restrict the flipper 2 from flipping downward.

[0037] Preferably, the cup lid 1 includes an upper cover 13 and an inner plug 14. The handle 6 is disposed on the upper surface of the upper cover 13, the elastic sealing element 4 is disposed at the lower end of the inner plug 14, a protrusion 131 is disposed on the inner side wall of the upper cover 13, and an outwardly extending extension platform 141 is disposed at the upper end of the inner plug 14. The extension platform 141 is inserted between the protrusion 131 and the top inner wall of the upper cover 13 for insertion and engagement.

[0038] Preferably, the side end of the extension platform 141 is provided with a positioning groove 142, and the inner side wall of the upper cover 13 is provided with a positioning block 132. The positioning block 132 is inserted into the positioning groove 142 and engaged. The inner plug 14 is provided with a vertical plate 143, which abuts against the inner wall of the limiting groove 11.

[0039] Preferably, the flap 2 has a reinforcing rib 24 protruding upwards on the upper surface of the connecting frame 23, and the reinforcing rib 24 has the same shape as the connecting frame 23.

[0040] Preferably, a return spring 8 is sleeved on the outside of the connecting rod 3. One end of the return spring 8 abuts against the bottom of the inner plug 14, and the other end of the return spring 8 abuts against the upper surface of the water sealing plate 5. The return spring 8 pushes the water sealing plate 5 to move downward.

[0041] Preferably, the connecting rod 3 has a rotating shaft 32, and the outer surface of the rotating shaft 32 is coaxially provided with abutting teeth 321. The connecting frame 23 has a connecting hole 231, and the rotating shaft 32 is inserted into the connecting hole 231 for insertion and engagement. The abutting teeth 321 abut against the inner wall of the connecting hole 231.

[0042] Specifically, such as Figures 1-4 As shown, when it is necessary to open the cup lid 1, hold the handle 6 with one hand and flip the flap 2 upward with your fingers. The inner end of the flap 2 drives the connecting rod 3 to move downward slightly through the connecting frame 23, so that the inside of the cup lid 1 is vented through the movement of the connecting rod 3, which makes it easier for the flap 2 to push the connecting rod 3 and the sealing plate 5 downward.

[0043] As the flap 2 rotates further upward, the inner end of the flap 2 contacts the pushing surface 31 and presses the connecting rod 3 downward until the pushing surface 31 is flush with the bottom wall of the receiving cavity 10. At this time, the inner end of the flap 2 presses against the pushing surface 31 and the bottom wall of the receiving cavity 10 and forms an interference fit, so that the flap 2 can be kept in the open state relatively stably.

[0044] like Figures 1-4 As shown, a sealing step is integrally formed on the inner wall of the cup opening, and the sealing step is diagonally arranged with the annular groove 52. When it is necessary to lock the cup lid 1, simply flip the flap 2 downwards and fasten it onto the cup lid 1. During the downward flipping of the flap 2, the flap 2 drives the connecting rod 3 and the water sealing plate 5 to move upwards through the lever principle. The water sealing plate 5 gradually extends into the elastic sealing element 4, and the lower inner wall of the elastic sealing element 4 gradually expands outwards along the pushing slope 51. Thus, when the flap 2 is fastened onto the cup lid 1, the water sealing plate 5 presses the upper side of the limiting ring 41 against the sealing step through the annular groove 52, and the lower side of the limiting ring 41 presses against the bottom wall of the annular groove 52. This clamps the limiting ring 41, so that the elastic sealing element 4 can effectively seal the cup opening.

[0045] When the flap 2 is rotated downwards, the inner wall of the elastic seal 4 comes into contact with the pushing slope 51 and expands outwards along the pushing slope 51. Thus, in the locked state, the elastic seal 4 is pressed against the inner wall of the cup opening from the inside out through the sealing plate 5. It does not only rely on the deformation angle of the elastic seal 4 itself to abut against the inner wall of the cup opening, but also improves the sealing effect of the elastic seal 4 on the cup opening in the locked state and extends the service life of the elastic seal 4.

[0046] like Figure 1 As shown, the handle 6 provides a point of leverage for the user's hand. When it is necessary to unlock the cup lid 1, one hand can be held on the handle 6 to directly turn the flip plate 2 upward, which improves the convenience of opening the cup lid 1. The rotation space 7 formed by the handle 6 and the cup lid 1 can protect the flip plate 2, reducing the possibility of accidentally touching the flip plate 2 when it is open and causing the flip plate 2 to rotate downward, which makes it more convenient to use.

[0047] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
