Description

Technical Field

[0001] The utility model belongs to the technical field of cups and relates to a rotary sealing cup cover and a cup. Background Art

[0002] Most of the existing push-piece covers do not have a sealing function, and only play a role in preventing spillage but not leakage. For the push-piece covers with sealing functions, the push pieces on the cover are tightly combined with the main cover, which makes it difficult to push the push pieces and inconvenient to operate. For example, the Chinese patent literature discloses a utility model patent for a cup cover with a rotary disassembly sliding switch, and the authorization announcement number is CN218164818U. The upper cover sliding member is arranged on the cover body, and the connecting rod of the upper cover sliding member passes through the cover body. The connecting rod and the rotating connecting member under the cover body are connected to each other through a buckle. The upper slider on the top of the rotating connecting member is stuck in the slide groove of the cover body. The cover body is provided with a water outlet, and the inner side of the bottom of the cover body is provided with an internal thread, and the top of the inner side of the cover body is provided with a leak-proof rubber ring. The cup cover assembled by the cover body, the rotating connecting member and the upper cover sliding member, the upper cover sliding member slides above the cover body, and the sliding of the rotating connecting member is linked to realize the closing and opening of the water outlet on the cover body, so as to achieve the sealing and leak-proof function. If the sealing effect between the rotary connector and the cover body is good, the upper cover sliding member needs to overcome a large resistance when sliding, and the operation is inconvenient. Summary of the invention

[0003] The utility model proposes a rotary sealing cup cover and a cup in view of the problems existing in the prior art, aiming to overcome the defect that the upper cover sliding part on the existing sealing push piece cover has a large sliding resistance.

[0004] The utility model is achieved in this way:

[0005] A rotary sealed cup cover, comprising a cover body, characterized in that the cover body is provided with a drinking port and a long strip opening, the cover body is provided with a connecting piece passing through the long strip opening, the upper end of the connecting piece is provided with an operating piece, and the lower end of the connecting piece is provided with a sealing piece, so that when the operating piece moves, the sealing piece covers or staggers the drinking port;

[0006] A rotating lifting structure is provided between the operating member and the sealing member, so that when the operating member rotates, the sealing member moves upward or downward.

[0007] The connecting piece can move along the long strip opening. When the user pushes the operating piece, the operating piece drives the connecting piece to move along the long strip opening, and the connecting piece drives the sealing piece to move. When the operating piece moves in a first direction, the sealing piece can move from a position offset from the drinking opening to a position covering the drinking opening. The sealing piece covers the drinking opening from below the drinking opening. When the operating piece moves in a second direction, the sealing piece can move from a position covering the drinking opening to a position offset from the drinking opening, thereby facilitating the drinking water under the cover body to pass smoothly through the drinking opening.

[0008] When the seal is in the position of covering the drinking opening, rotating the operating member can move the seal upward, so that the sealing ring on the seal can be tightly abutted against the cover body, thereby sealing the drinking opening and preventing the liquid under the cover body from flowing out of the drinking opening. Rotating the operating member in the opposite direction can move the seal downward, so that the sealing ring on the seal and the cover body form a certain gap or slight contact, reducing the resistance of pushing the operating member. In this way, the cup cover can easily push the operating member and achieve a good seal on the drinking opening.

[0009] Preferably, the rotary lifting structure includes a first thread on the operating member, and a second thread on the connecting member and matched with the first thread, and the lower end of the connecting member is fixed to the sealing member. The thread matching allows the operating member and the connecting member to be connected to prevent the operating member from being separated, and at the same time, the rotation of the operating member relative to the connecting member can drive the connecting member to move up and down, thereby driving the sealing member to move up and down.

[0010] Preferably, a circumferential positioning structure is provided between the connecting member and the cover body, so that when the operating member rotates relative to the cover body, the connecting member is circumferentially fixed relative to the cover body. When the operating member is rotated, the circumferential positioning structure can prevent the connecting member from rotating with the operating member, ensuring that the operating member can rotate relative to the connecting member, thereby ensuring that the rotation of the operating member can drive the connecting member to move up and down.

[0011] Preferably, the circumferential positioning structure includes a positioning plane located in the middle of the connector, the positioning plane cooperates with the side wall of the long strip opening to fix the connector circumferentially relative to the cover body. The cooperation between the planes can prevent the connector from rotating relative to the cover body.

[0012] Preferably, when the sealing member covers the drinking opening, the operating member covers the drinking opening from above the drinking opening, so that the operating member can play a dustproof role and is conducive to keeping the drinking opening clean.

[0013] Preferably, the sealing member is provided with a sealing ring, the cover body is provided with a sealing rib at the periphery of the drinking opening, when the cup cover is in a sealed state, the sealing ring and the sealing rib abut against each other, and when the cup cover is in a dustproof state, there is a gap between the sealing ring and the sealing rib. The abutment of the sealing rib and the sealing ring is conducive to the deformation of the sealing ring, thereby improving the sealing performance.

[0014] Preferably, the sealing member and the connecting member are detachably connected by a thread, the outer diameter of the upper end of the connecting member is larger than the width of the long strip opening, and the outer diameter of the lower end of the connecting member is smaller than the width of the long strip opening. The larger outer diameter of the upper end of the connecting member is conducive to improving the connection strength between the connecting member and the operating member. During installation, the operating member and the connecting member can be fixed first, then the connecting member can be passed downward through the long strip opening, and then the sealing member can be fixed to the lower end of the connecting member.

[0015] Preferably, an elastic member is provided between the sealing member and the connecting member, a buckle is provided on the side wall of the long opening, and a slot is provided on the side wall of the connecting member, and when the cup cover is in a drinking state, the buckle is engaged in the slot. The elastic member is conducive to improving the tightness of the sealing member and the connecting member to prevent the two from loosening.

[0016] Preferably, the sealing member has a connection groove with an upward opening, the side wall of the connection groove has a thread that cooperates with the lower end of the connection member, and the elastic member is located in the connection groove and abuts against the lower end of the connection member. The elastic member is placed in the connection groove to prevent liquid from contacting the elastic member, which is conducive to extending the service life of the elastic member.

[0017] A cup, characterized in that it comprises the above-mentioned cup cover and also comprises a cup body, wherein the cup cover is detachably fixed to the cup body.

[0018] The utility model has the following beneficial effects: rotating the operating member can move the sealing member upward, so that the sealing ring on the sealing member can be tightly abutted against the cover body, thereby sealing the drinking opening and preventing the liquid under the cover body from flowing out of the drinking opening. Rotating the operating member in the opposite direction can move the sealing member downward, so that the sealing ring on the sealing member and the cover body form a certain gap or slight contact, reducing the resistance of pushing the operating member. In this way, the cup cover can not only push the operating member more easily, but also achieve a good seal on the drinking opening. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0030] This embodiment provides a cup, specifically a coffee cup, which is a specific application of the innovative solution of the utility model on a coffee cup. The innovative solution of the utility model can also be applied to cups such as thermos cups.

[0031] like Figure 1-9 As shown, the cup includes a cup cover and a cup body 100, and the cup cover is detachably fixed to the cup body 100. The cup cover includes a cover body 200, and the cover body 200 has a drinking port 210 and a long strip opening 220. The cover body 200 is provided with a connecting piece 300 passing through the long strip opening 220, and an operating piece 400 is provided at the upper end of the connecting piece 300, and a sealing piece 500 is provided at the lower end of the connecting piece 300, so that when the operating piece 400 moves, the sealing piece 500 covers or staggers the drinking port 210. The connecting member 300 can move along the long strip opening 220. When the user pushes the operating member 400, the operating member 400 drives the connecting member 300 to move along the long strip opening 220, and the connecting member 300 drives the sealing member 500 to move. When the operating member 400 moves in the first direction, the sealing member 500 can move from a position offset from the drinking port 210 to a position covering the drinking port 210. The sealing member 500 covers the drinking port 210 from below the drinking port 210. When the operating member 400 moves in the second direction, the sealing member 500 can move from a position covering the drinking port 210 to a position offset from the drinking port 210, thereby facilitating the drinking water below the cover body 200 to pass through the drinking port 210 smoothly.

[0032] A rotating lifting structure is provided between the operating member 400 and the sealing member 500, so that when the operating member 400 is rotated, the sealing member 500 moves upward or downward. When the sealing member 500 is in a position covering the drinking opening 210, rotating the operating member 400 can move the sealing member 500 upward, so that the sealing ring 510 on the sealing member 500 can be tightly abutted against the cover body 200, thereby sealing the drinking opening 210 and preventing the liquid under the cover body 200 from flowing out of the drinking opening 210. Rotating the operating member 400 in the opposite direction can move the sealing member 500 downward, so that the sealing ring 510 on the sealing member 500 and the cover body 200 form a certain gap or slight contact, thereby reducing the resistance of pushing the operating member 400. In this way, the cup cover can not only push the operating member 400 relatively easily, but also achieve a good seal on the drinking opening 210.

[0033] like Figure 4 , 6 As shown in FIGS. 8 and 9, the rotary lifting structure includes a first thread 410 located on the operating member 400, and a second thread 310 located on the connecting member 300 and matched with the first thread 410, and the lower end of the connecting member 300 is fixed to the sealing member 500. The thread matching allows the operating member 400 and the connecting member 300 to be connected to prevent the operating member 400 from being separated, and at the same time, the rotation of the operating member 400 relative to the connecting member 300 can drive the connecting member 300 to move up and down, thereby driving the sealing member 500 to move up and down. In other optional embodiments, tilting blocks and tilting grooves can also be provided on the operating member 400 and the connecting member 300 respectively so that when the operating member 400 rotates, the connecting member 300 can move up and down, wherein the downward movement of the connecting member 300 can be based on the gravity of the connecting member 300 and the sealing member 500.

[0034] Since the operating member 400 and the sealing member 500 are connected by the connecting member 300, the rotary lifting structure of this embodiment is located between the operating member 400 and the connecting member 300, which belongs to a type of rotary lifting structure located between the operating member 400 and the sealing member 500. In other optional embodiments, the connecting member 300 and the operating member 400 may also be connected as one body, in which case the rotary lifting structure is located between the connecting member 300 and the sealing member 500.

[0035] In other optional embodiments, the connector 300 and the sealing member 500 may be integrally connected, in which case the outer diameter of the upper end of the connector 300 is smaller than or equal to the width of the long strip opening 220, so that the connector 300 can be easily installed from bottom to top.

[0036] A circumferential positioning structure is provided between the connecting member 300 and the cover body 200, so that when the operating member 400 rotates relative to the cover body 200, the connecting member 300 is circumferentially fixed relative to the cover body 200. When the operating member 400 is rotated, the circumferential positioning structure can prevent the connecting member 300 from rotating with the operating member 400, ensuring that the operating member 400 can rotate relative to the connecting member 300, thereby ensuring that the rotation of the operating member 400 can drive the connecting member 300 to move up and down. When the operating member 400 rotates 90 degrees, the dustproof state and the sealing state of the cup cover can be switched.

[0037] Specifically, the circumferential positioning structure includes a positioning plane 320 located in the middle of the connecting member 300, and the positioning plane 320 cooperates with the side wall of the long strip opening 220 to fix the connecting member 300 circumferentially relative to the cover body 200. The cooperation between the planes can prevent the connecting member 300 from rotating relative to the cover body 200. In other optional embodiments, the circumferential positioning structure can also be a non-planar surface, as long as the horizontal length of the portion of the connecting member 300 in the long strip opening 220 is greater than the width of the long strip opening 220, so that the connecting member 300 cannot achieve 90-degree rotation in the long strip opening 220, the rotation angle of the connecting member 300 is limited, and the operating member 400 can achieve more than 90-degree rotation, that is, the rotation of the operating member 400 drives the connecting member 300 to move up and down.

[0038] In an embodiment without a circumferential positioning structure, the operating member 400 may also be pulled upward so that the sealing ring 510 on the sealing member 500 and the cover body 200 generate sufficient friction, thereby preventing the sealing member 500 from rotating when the operating member 400 rotates.

[0039] like Figure 2 , 4 As shown, when the sealing member 500 covers the drinking opening 210, the operating member 400 covers the drinking opening 210 from above the drinking opening 210. In this way, the operating member 400 can play a dustproof role, which is conducive to keeping the drinking opening 210 clean.

[0040] like Figure 4 , 6 As shown, the sealing member 500 is provided with a sealing ring 510, and the cover body 200 is provided with a sealing rib 230 at the periphery of the drinking port 210. When the cup cover is in a sealed state, the sealing ring 510 and the sealing rib 230 abut against each other, and when the cup cover is in a dustproof state, there is a gap between the sealing ring 510 and the sealing rib 230. The abutment of the sealing rib 230 and the sealing ring 510 is conducive to the deformation of the sealing ring 510, thereby improving the sealing performance.

[0041] like Figure 4 , 6As shown, the sealing member 500 and the connecting member 300 are detachably connected by threads, the outer diameter of the upper end of the connecting member 300 is larger than the width of the long strip opening 220, and the outer diameter of the lower end of the connecting member 300 is smaller than the width of the long strip opening 220. The larger outer diameter of the upper end of the connecting member 300 is conducive to improving the connection strength between the connecting member 300 and the operating member 400. During installation, the operating member 400 and the connecting member 300 can be fixed first, then the connecting member 300 can be passed downward through the long strip opening 220, and then the sealing member 500 can be fixed to the lower end of the connecting member 300. In other optional embodiments, the sealing member 500 can also be fixed or integrally connected to the lower end of the connecting member 300 by clamping.

[0042] like Figure 4 , 6 As shown, an elastic member 600 is provided between the sealing member 500 and the connecting member 300. The elastic member 600 is conducive to improving the tightness of the sealing member 500 and the connecting member 300 to prevent the two from loosening. The elastic member 600 adopts a silicone pad, and the sealing member 500 has a connecting groove with an upward opening, and the side wall of the connecting groove has a thread that cooperates with the lower end of the connecting member 300. The elastic member 600 is located in the connecting groove and abuts against the lower end of the connecting member 300. The elastic member 600 is placed in the connecting groove, which can prevent liquid from contacting the elastic member 600, which is conducive to extending the service life of the elastic member 600.

[0043] Furthermore, the side wall of the long opening 220 has a buckle 221, and the side wall of the connecting member 300 has a slot 330. When the cup cover is in the drinking state, the buckle 221 is engaged in the slot 330 to prevent the operating member 400 from sliding and blocking the drinking opening 210 during drinking.
