Description

Technical Field

[0001] The invention relates to a cup cover and a liquid container having the same. Background Art

[0002] The lid of a liquid container such as a water cup or coffee cup is often tightly connected to the cup body by means of threads or buckles. When drinking the liquid in the cup body, it is necessary to open the entire lid or part of the lid. There are two existing ways to open it: unscrewing the lid to separate it from the cup body; opening a part of the lid so that the liquid in the cup can flow out of the lid from the opened part. Since unscrewing the lid is inconvenient, more and more lids have separate opening and closing structures.

[0003] A Chinese invention patent application with application publication number CN107853959A (hereinafter referred to as prior art 1) discloses a convenient flap-opening water outlet cover, which includes a cover body with a water outlet, a flap is rotatably mounted on the upper part of the cover body, a water blocking plate is arranged on the lower side of the flap, and one end of the water blocking plate is hinged to one side of the cover body. The flap is connected to the middle part of the water blocking plate through two circular guide lugs and an eccentric shaft, and the flap drives the circular guide lug to rotate when opening and closing, and the circular guide lug drives the eccentric shaft fixed between the two circular guide lugs to swing up and down with the rotation of the flap, thereby causing the water blocking plate to rotate to open or close the water outlet with the up and down swing of the eccentric shaft.

[0004] The water outlet cover structure disclosed in the prior art 1 has a wide range of applications because it can realize the one-handed opening and closing of the cup cover. However, in order to establish the motion relationship between the rotation of the lift-off piece and the rotation of the water blocking plate, the middle part of the water blocking plate is rotatably connected to the eccentric shaft, and the water blocking plate is rotatably connected to one side of the cup cover, and its connection with the eccentric shaft deviates from the position where it is rotatably connected to the cup cover. Therefore, in the process of the eccentric shaft swinging up and down, the water blocking plate is equivalent to being pushed away a very small distance (i.e., the distance of the eccentric shaft swinging up and down) at a position deviating from its rotation axis. Due to the size of the cup cover itself, the distance of the eccentric shaft moving up and down is very small, which is why the water blocking plate can only be turned away by a very small angle relative to the lift-off piece. When cleaning the cup cover, there is a dead angle between the water blocking plate and the lift-off piece that is difficult for cleaning tools to reach. When the cup cover is stained with liquids that need to be cleaned, such as coffee and juice, this dead angle will cause a health hazard to the liquid container itself. Summary of the invention

[0005] Through the above analysis, it can be seen that there is such a contradiction in the design of the opening structure of the cup cover in the prior art: there must be a linkage relationship between the structure for sealing the water outlet and the structure for users to flip open, but this linkage relationship inevitably makes the two parts unable to be "independent of each other", causing difficulties in cleaning. In particular, when this design is applied to the cup cover, the structural size, weight and ease of operation all restrict the improvement of the structure.

[0006] In view of this, it is necessary to provide a cup lid and a liquid container having the same to address the above-mentioned problems, wherein the flap and the rotating plate of the cup lid are independently rotatable and connected to the two sides of the cover body. When the cup lid needs to be cleaned, the rotating plate can be rotated to a larger angle independently of the flap, thereby facilitating the cleaning process of the cup lid.

[0007] A cup cover comprises a cover body, a water outlet penetrating the cover body is formed on the cover body, a flap is rotatably connected to one side surface of the cover body, a rotating plate is rotatably connected to the other side surface of the cover body, the rotating plate is maintained in a position closing the water outlet under the action of a reset member, an actuating member is arranged on a side surface of the rotating plate facing the water outlet, an actuating protrusion is arranged on the flap, and during the process of the flap being rotated to open, the actuating protrusion contacts the actuating member at a position deviating from the rotating axis of the rotating plate, pushing the rotating plate to rotate and release the closure of the water outlet.

[0008] In one embodiment, the actuating member includes an opening section protruding toward the water outlet and a locking groove concave away from the water outlet. When the actuating protrusion contacts the opening section, the rotating piece rotates to open the water outlet. When the actuating protrusion enters the locking groove, the flap is locked.

[0009] In one of the embodiments, a locking protrusion is provided on the flap, and after the flap is rotated until the actuating protrusion escapes from the locking groove, the locking protrusion can be locked into the locking groove.

[0010] In one embodiment, when the flap is in the closed position, the actuating protrusion abuts against an end of the opening section.

[0011] In one embodiment, the cover body has a second buckling edge corresponding to the fully opened position of the flap, and when the locking protrusion is locked in the locking groove, the flap abuts against the second buckling edge.

[0012] In one of the embodiments, a spring buckle point is provided on the cover body, and the reset member is configured as a torsion spring, one end of which is clamped to the rotating piece, and the other end is clamped to the spring buckle point.

[0013] In one embodiment, the actuating member and the rotating plate are integrally formed.

[0014] In one of the embodiments, a sealing ring surrounding the water outlet is further provided on the rotating plate.

[0015] In one of the embodiments, a sealing flange is formed on a side surface of the water outlet facing the rotating plate, and the sealing ring is pressed against the sealing flange.

[0016] In one embodiment, the flap is rotatably connected to the cover body via a pivot shaft, one end of the flap extends beyond the edge of the cover body to form a driving end, and the actuating protrusion and the driving end are respectively located at two ends of the pivot shaft.

[0017] In one of the embodiments, the cover body has a first buckling edge corresponding to the closed position of the flap, and the first buckling edge and the flap are respectively provided with a buckling groove and a buckling protrusion.

[0018] Another aspect of the present invention provides a liquid container, which includes the aforementioned cup cover.

[0019] In the above cup cover, the rotating piece is kept in the position of closing the water outlet under the action of the reset member. The actuating protrusion on the flap contacts the actuating member on the rotating piece as the flap rotates to open, thereby pushing the rotating piece to overcome the force of the reset member and flip open, thus establishing a linkage relationship between the rotating piece and the flap. When cleaning the cup cover, the flap and the rotating piece can rotate independently relative to the cover body, making cleaning more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0037] According to a cup cover of one embodiment of the present invention, Figures 1 to 9As shown in , it includes a cover body 1, and a water outlet 10 penetrating the cover body 1 is formed on the cover body 1. When the cup cover is used with a liquid container such as a water cup, a coffee cup, etc., the cup cover is closed onto the mouth of the cup. In some embodiments, a cover body thread 18 is provided on the outer peripheral surface of the cover body 1, and when the cup cover is closed onto the mouth of the cup, the cover body thread 18 is screwed onto the thread of the mouth of the cup. It is understandable that the cup cover can also be fixed to the mouth of the cup by snap-fitting or other connection forms. The aforementioned "water outlet 10 penetrating the cover body 1" means that when the cover body 1 is closed and buckled, the liquid in the liquid container can flow out through the water outlet 10.

[0038] A flap 2 is rotatably connected to one side of the cover 1, and a rotating piece 4 is rotatably connected to the other side. In particular, with the state where the cup cover is closed to the cup mouth as a reference, the rotating piece 4 is rotatably arranged on the side of the cover 1 facing the inside of the liquid container, and the flap 2 is rotatably connected to the side of the cover located outside the liquid container, so that the user can open or close the cup cover by operating the flap 2.

[0039] The cover body 1 is provided with a rotating piece pivot 15 on one side surface of the rotating piece 4 to which the rotating piece 4 is rotatably connected, and the rotating shaft 40 of the rotating piece 4 is rotatably connected to the rotating piece pivot 15. The rotating piece 4 is maintained at the position of closing the water outlet 10 by a reset member. It can be understood that the function of the reset member is to maintain the closed state of the rotating piece 4 relative to the water outlet 10, that is, when the force that pushes the rotating piece 4 to rotate to open the water outlet 10 disappears, the reset member can drive the rotating piece 4 to return to the position of closing the water outlet 10. In some embodiments, the reset member is configured as a torsion spring 6, and the torsional elastic force of the torsion spring 6 keeps the rotating piece 4 at the position of closing the water outlet 10. A spring buckle point 16 is provided on the cover body 1, and correspondingly, a buckle point (not shown in the figure) is also provided at a corresponding position on the rotating piece 4, and the two ends of the torsion spring 6 are clamped to the buckle point on the rotating piece 4 and the spring buckle point 16 respectively.

[0040] The cover body 1 is provided with a flap pivot 11 on one side surface to which the flap 2 is rotatably connected, and a pivot shaft 22 of the flap 2 is rotatably connected to the flap pivot 11. With reference to the location of the pivot shaft 22, one end of the flap 2 preferably extends beyond the edge of the cover body 1 to form a driving end 24, and an actuating protrusion 20 is located at the other end of the flap 2. In some embodiments, the rotation of the flap 2 has two extreme positions: a closed position and a fully open position, and correspondingly, a first snapping edge 12 and a second snapping edge 13 are provided on the cover body 1. A snapping groove 14 and a snapping protrusion 23 are also provided on the first snapping edge 12 and the flap 2, respectively. When the flap 2 is rotated to the closed position, the snapping protrusion 23 is snapped into the snapping groove 14, thereby limiting the flipping of the flap 2. It is understandable that the setting positions of the snapping protrusion 23 and the snapping groove 14 can be interchanged.

[0041] An actuating member 3 is disposed on one side of the rotating piece 4 facing the water outlet 10, and an actuating protrusion 20 is correspondingly disposed on the end of the flap 2 opposite to the driving end 24. When the flap 2 rotates from the closed position to the fully open position, the actuating protrusion 20 contacts the actuating member 3 at a position deviating from the rotating shaft 40, so that the actuating protrusion 20 biases the actuating member 3, thereby pushing the rotating piece 4 to rotate.

[0042] Reference Figure 8 As shown, the actuating member 3 includes an opening section 30, a locking groove 31 and a slope section 32, wherein: the opening section 30 is set as an inclined arc structure protruding toward the water outlet 10; the locking groove 31 is set as a groove structure concave inwardly facing the water outlet 10; and the slope section 32 is set as an inclined surface or an inclined arc structure inclined from bottom to top toward the water outlet 10. In some embodiments, when the flap 2 is in the closed position, the actuating protrusion 20 abuts against the end of the opening section 30, and when the flap 2 starts to rotate, the actuating protrusion 20 almost simultaneously contacts the opening section 30, so that the cup cover can be opened by slightly rotating the flap 2, and when the rotation angle of the flap 2 is not large, the flap 2 can also form a certain shielding for the water outlet 10. When the liquid container matched with the cup cover contains boiling water or other high-temperature liquids, the flap 2 can be slightly rotated to discharge hot air from the opened water outlet 10, and due to the shielding effect of the flap 2, the hot air will not be directly sprayed onto the user's hand.

[0043] When the actuating protrusion 20 enters the locking groove 31 as the flap 2 further rotates, the flap 2 is locked. At this time, without the action of external force, the flap 2 stops at this position and does not deflect further. In some embodiments, a locking protrusion 21 is further provided on the flap 2, and during the process of the flap 2 rotating from the closed position to the fully open position, the locking protrusion 21 contacts the actuating member 3 after the actuating protrusion 20. A preferred embodiment is that when the actuating protrusion 20 leaves the locking groove 31 as the flap 2 further rotates under the action of external force, after sliding over the inclined surface section 32, the locking protrusion 21 begins to contact the actuating member 3. In other words, when the actuating protrusion 20 is about to withdraw from the contact with the actuating member 3, the locking protrusion 21 is about to enter the contact with the actuating member 3. At this time, the opening section 30, the locking groove 31 and the inclined section 32 on the actuating member 3 are all located between the actuating protrusion 20 and the locking protrusion 21. At this time, the flap 2 will not flip over without external force. After that, the locking protrusion 21 contacts the three surfaces on the actuating member 3, driving the rotating plate 4 to rotate around the rotating shaft 40.

[0044] Furthermore, when the flap 2 rotates to the fully open position, the driving end 24 contacts the second locking edge 13, and at this time, the locking protrusion 21 is locked in the locking groove 31. In other words, when the flap 2 is in the fully open position, the flap 2 is affected by the locking force between the locking protrusion 21 and the locking groove 31, and is kept in this position, and will not rotate without external force. When the user drinks the liquid in the container, there is no need to fix the flap 2 in this position by hand.

[0045] A cam motion mechanism similar to that of an expansion type is formed between the actuating member 3 and the actuating protrusion 20 and the locking protrusion 21. The reset member keeps the actuating protrusion 20 and / or the locking protrusion 21 in contact with the surface of the actuating member 3, and as the inclination of the surface of the actuating member 3 changes, the actuating protrusion 20 and / or the locking protrusion 21 rise and fall, thereby biasing the rotating plate 4 at the rotating shaft 40 that deviates from the rotating plate 4. This matching form well resolves the problem of linkage and independence between the flap 2 and the rotating plate 4, that is, the actuating protrusion 20 and the locking protrusion 21 are in contact with the surface of the actuating member 3 to realize the linkage between the flap 2 and the rotating plate 4 according to the expected movement law, and this contact can be disengaged at any time. When cleaning the cup cover, the rotating plate 4 can be turned by external force to a larger angle, which is convenient for cleaning the cup cover.

[0046] The actuating member 3 and the rotating piece 4 can be integrally formed, or they can be assembled and fixed by separate processing and common fixed connection forms such as bonding and clamping. The rotating piece 4 is also provided with a sealing ring 5 surrounding the water outlet 10. The sealing ring 5 can be directly fixed to the outer periphery of the rotating piece 4 or the active member 4 by its own elastic tension, or it can be fixed by Figure 8 In the manner shown in the figure, the sealing groove 41 is provided on the rotating plate 4 to fix it. Further, a sealing flange 17 is formed on one side of the water outlet 10 facing the rotating plate 4. When the rotating plate 4 closes the water outlet 10 under the action of the reset member, the sealing ring 5 is pressed against the sealing flange 17.

[0047] In addition, another aspect of the present invention provides a liquid container, which includes the cup cover of any one of the above embodiments.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
