Description

Technical Field

[0001] The utility model relates to a water cup, in particular to a cup cover and a water cup with a detachable lock tongue. Background Art

[0002] A water cup is a water container, generally including a cup body and a cup cover. The cup cover is provided with a water outlet. A flip cover is arranged on the cup cover to seal the water outlet. When the flip cover is opened, the user can directly drink through the water outlet; or an elastic telescopic straw is arranged in the cup body, and when the flip cover is opened, the straw pops out from the water outlet for the user to drink. In order to prevent the water in the cup from pouring out when the flip cover is opened when the cup is idle, a locking structure is generally added to the flip cover to lock the flip cover.

[0003] For example, a lockable thermos cup disclosed in the Chinese utility model patent CN219556879U includes a cup body and a cup cover. The cup cover is provided with a locking assembly and a water outlet. The locking assembly includes a locking seat hinged to the rear end of the cup cover. A lock tongue protrudes forward from the locking seat to the outside of the front end of the locking seat. A lock groove is opened at the position of the cup cover corresponding to the lock tongue. When the lock tongue is inserted into the lock groove, the water outlet is closed by the locking seat. An elastic member for providing a reset force to the lock tongue is arranged on the locking seat. The locking seat includes an upper connecting seat and a lower connecting seat. The lower connecting seat is provided with a buckling portion extending upward. When the lower connecting seat and the upper connecting seat are aligned, the buckling portion is buckled with the upper connecting seat, so that an activity cavity for the lock tongue to slide back and forth is formed between the upper connecting seat and the lower connecting seat.

[0004] The existing cup cover has the problem that since people need to replenish water many times a day, it is necessary to frequently slide the lock tongue to unlock and lock. Frequent sliding of the lock tongue for a long time is likely to cause damage to the lock tongue or the elastic member to lose its elasticity, thus affecting the locking effect of the flip cover. It is necessary to disassemble the locking seat to replace the internal lock tongue or elastic member. The existing upper connecting seat and lower connecting seat of the locking seat are connected by buckling through the buckling portion. After buckling, it is very difficult to disassemble the upper connecting seat and the lower connecting seat. If forced to disassemble, it is easy to cause damage to the buckling portion, making the upper connecting seat and the lower connecting seat unable to form a buckle again. If the lock tongue or elastic member is not disassembled and replaced, the entire cup cover or flip cover needs to be replaced, increasing the cost. Content of the Utility Model

Specific embodiments

[0036] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0037] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0038] Figures 1 - 17 As shown, the water cup includes a cup body 1 and a cup lid. The upper end of the cup body 1 has a cup mouth, and the cup lid covers the cup mouth.

[0039] Figure 2 As shown, the cup body 1 includes an outer shell 5 and an inner liner 6. The upper ends of the outer shell 5 and the inner liner 6 are connected and there is a vacuum cavity between them.

[0040] Figure 7 , Figure 8As shown, the cup lid is threadedly connected to the cup mouth. The cup lid includes a cup lid body 2, a flip lid 3 hinged to the rear end of the cup lid body 2, and a locking member 4 that slides back and forth on the flip lid 3. An assembly cavity 17 for installing the locking member 4 is provided on the flip lid 3. The front end of the locking member 4 is provided with a locking tongue 32, and the locking tongue 32 protrudes outside the front side of the assembly cavity 17. An elastic member that provides a reset force to the locking member 4 is provided in the assembly cavity 17. A water outlet 29 and a locking groove 34 corresponding to the locking tongue 32 are provided on the cup lid body 2. When the flip lid 3 is flipped down to cover the water outlet 29 to close the water outlet 29, the locking tongue 32 is inserted into the locking groove 34 to restrict the flip lid 3 from flipping up and opening.

[0041] A straw 8 is provided inside the cup body 1. The upper end of the straw 8 is located inside the water outlet 29. The lower end of the straw 8 is connected to an elastic silica gel tube 7, and the total length of the straw 8 and the silica gel tube 7 after connection is greater than the height of the cup body 1.

[0042] Figures 1 - 3 As shown, when it is necessary to close the water outlet 29, move the locking member 4 backward so that the locking tongue 32 at the front end of the locking member 4 retracts into the assembly cavity 17. At the same time, flip the flip lid 3 downward so that the flip lid 3 covers the water outlet 29 to close the water outlet 29. At this time, the locking tongue 32 is opposite to the locking groove 34 on the cup lid body 2. Release the locking member 4, and the elastic member pushes the locking member 4 forward to reset, so that the locking tongue 32 protrudes forward outside the front side of the assembly cavity 17 and snaps into the opposite locking groove 34 to form a lock. In this state, the silica gel tube 7 is bent, the upper end of the straw 8 is pressed by the flip lid 3 at the water outlet 29, and the upper end of the straw 8 abuts against the bottom of the flip lid 3; Figures 4 - 6 As shown, when the locking member 4 is moved so that the locking tongue 32 disengages from the locking groove 34, the rotation restriction on the flip lid 3 is released, and the flip lid 3 is flipped upward to open the water outlet 29. Since the pressure on the upper end of the straw 8 is removed, the silica gel tube 7 rebounds to eject the upper end of the straw 8 out of the water outlet 29 for the user to drink.

[0043] A sealing plug 23 is fixed to the bottom of the flip lid 3. When the flip lid 3 is flipped downward to cover above the water outlet 29, the sealing plug 23 is plugged into the water outlet 29 to seal the water outlet 29. The sealing plug 23 is made of elastic silica gel or rubber.

[0044] Figure 3 As shown, preferably, an installation portion 26 is provided at the bottom of the flip lid 3. The sealing plug 23 has a central hole 28. The sealing plug 23 is sleeved outside the installation portion 26 through the central hole 28. The lower end of the installation portion 26 has a flanging 25. A clamping groove 24 is provided on the inner wall of the central hole 28 of the sealing plug 23, and the flanging 25 is snapped into the clamping groove 24 to fix the sealing plug 23 to the bottom of the flip lid 3.

[0045] In addition, a positioning groove 27 is provided at the bottom of the installation part 26. The positioning groove 27 is opposite to the central hole 28. When the flip cover 3 is flipped downward to close the water outlet 29, the upper end of the straw 8 is inserted into the positioning groove 27 to limit displacement.

[0046] A limiting ring 53 extending downward is provided below the water outlet 29 of the cup cover body 2. The upper end of the straw 8 is positioned and accommodated within the limiting ring 53. Since the limiting ring 53 is provided below the water outlet 29, when the flip cover 3 presses on the water outlet 29 or the flip cover 3 is flipped upward to open, the upper end of the straw 8 is always restricted within the limiting ring 53.

[0047] The straw 8 includes a tube body 50 and a nozzle 51. The nozzle 51 is connected to the upper end of the tube body 50, and the silicone tube 7 is connected to the lower end of the tube body 50. When the flip cover 3 covers the water outlet 29 to close the water outlet 29, the upper end of the nozzle 51 is inserted into the positioning groove 27; when the flip cover 3 is flipped upward to open the water outlet 29, the nozzle 51 pops out from the water outlet 29 for the user to drink water.

[0048] An outer ring edge 52 is provided at the lower end of the nozzle 51. When the nozzle 51 pops out from the water outlet 29, the outer ring edge 52 abuts against the lower edge of the limiting ring 53 to restrict the straw 8 from moving upward further.

[0049] The nozzle 51 is detachable from the tube body 50, and the tube body 50 is detachable from the silicone tube 7. Disassembling the nozzle 51, the tube body 50, and the silicone tube 7 facilitates the user to clean them. Preferably, the lower end of the nozzle 51 is tightly fitted on the upper end of the tube body 50 and can be pulled apart between the two. The silicone tube 7 is sleeved on the lower end of the tube body 50, and there is an interference fit between the two, and the silicone tube 7 can be pulled off from the lower end of the tube body 50.

[0050] A threaded connection portion 9 for threaded connection with the cup mouth of the cup body 1 is provided on the cup cover body 2.

[0051] Figures 9 - 17 As shown, the flip cover 3 includes an upper cover body 31 and a lower cover body 30. A slot 46 for the upper cover body 31 to slide and insert is provided on the lower cover body 30. Slide rails for sliding cooperation with both sides of the upper cover body 31 are provided on the slot walls on both left and right sides of the slot 46. Positioning grooves 27 are provided on the slot walls on both left and right sides of the slot 46. Positioning protrusions 44 cooperating with the positioning grooves 27 are provided on the side walls on both left and right sides of the upper cover body 31. And the slot walls on both left and right sides of the slot 46 and / or the side walls on both left and right sides of the upper cover body 31 are elastic. When the upper cover body 31 slides and inserts into the slot 46, the positioning protrusions 44 are elastically deformed through the slot walls of the slot 46 and / or the side walls of the upper cover body 31 and snap into the positioning grooves 27. At this time, an assembly cavity 17 for assembling and locking the locking member 4 is formed between the upper cover body 31 and the lower cover body 30.

[0052] The upper cover body 31 is slidably inserted into the slot 46 in its front-rear direction to form a connection with the lower cover body 30. The front-rear direction is the length direction of the upper cover body 31 in the attached drawing.

[0053] The assembly cavity 17 for installing the locking member 4 is formed by the upper cover body 31 slidingly inserted into the slot 46 on the lower cover body 30. When it is necessary to replace the locking member 4 with a locking tongue 32 or the elastic member, the upper cover body 31 and the lower cover body 30 are slid relative to each other, so that the positioning convex block 44 is disengaged from the positioning groove 27 to release the locking of the relative movement between the upper cover body 31 and the lower cover body 30. At this time, the upper cover body 31 can be slid out backward from the slot 46 to open the assembly cavity 17, and the locking member 4 with the locking tongue 32 or the elastic member installed inside is removed. The upper cover body 31 and the lower cover body 30 are combined and connected or disassembled by a sliding push-pull method similar to a drawer, which is more convenient for disassembly and assembly. And during the disassembly and assembly process, the positioning convex block 44 is engaged with or disengaged from the positioning groove 27 by the elastic deformation of the slot wall of the slot 46 and / or the side wall of the upper cover body 31. This process is not easy to damage the upper cover body 31 and the lower cover body 30, and the connection structure is more firm.

[0054] Figure 13 、 Figure 15 、 Figure 16 As shown, the upper cover body 31 includes a cover plate 10 and a bottom protrusion 18 provided at the bottom of the cover plate 10 and slidably inserted into the slot 46. The bottom protrusion 18 includes a rear side plate 41 and two first side plates 42 arranged on the left and right. The rear side plate 41 and the two first side plates 42 on the left and right enclose an upper slot 45. Positioning convex blocks 44 are provided on the outer side walls of the two first side plates 42. The lower cover body 30 includes a bottom plate 40, second side plates 43 provided on the left and right sides of the bottom plate 40, and a front side plate 47 provided on the front side of the bottom plate 40. A slot 46 is formed between the two second side plates 43. Slide rails and positioning grooves 27 are provided on the opposite inner surfaces of the two second side plates 43. When the bottom protrusion 18 slides forward from the opening at the rear of the lower cover body 30 and is inserted into the slot 46, by continuously moving the bottom protrusion 18 forward, the positioning convex block 44 is engaged with the positioning groove 27 to limit the relative movement between the upper cover body 31 and the lower cover body 30. At this time, the front side plate 47 blocks the opening at the front side of the bottom protrusion 18, and the rear side plate 41 blocks the opening at the rear side of the lower cover body 30. The cover plate 10, the rear side plate 41, the first side plates 42, the second side plates 43, the bottom plate 40, and the front side plate 47 enclose the assembly cavity 17. Preferably, the bottom protrusion 18 is U-shaped.

[0055] The rear end of the cover plate 10 is hinged to the top of the cup cover body 2.

[0056] Preferably, the first side plate 42 and the second side plate 43 are elastic.

[0057] Preferably, the positioning convex block 44 is provided at the rear end of the outer side surface of the first side plate 42, and the positioning groove 27 is provided at the rear end of the inner side surface of the second side plate 43.

[0058] Preferably, the slide rail is a chute 37 provided on the groove wall of the slot 46. The chute 37 extends forward from the rear of the second side plate 43. Both ends of the chute 37 penetrate the front and rear surfaces of the second side plate 43 and form notches on the surfaces on both sides. Sliding blocks 38 extending forward from the rear are provided on the outer sides of the two first side plates 42. The positioning convex block 44 is located above the sliding block 38, and the positioning groove 27 is provided above the chute 37.

[0059] When the upper cover 31 and the lower cover 30 are connected, the bottom protrusion 18 is inserted into the slot 46 from the opening at the rear of the lower cover 30. The sliding blocks 38 on the two first side plates 42 are respectively inserted into the chute 37 from the notches on the rear sides of the two second side plates 43. Move the upper cover 31 forward until the positioning convex block 44 is snapped into the positioning groove 27. During this process, the positioning convex block 44 contacts and forms extrusion with the second side plate 43 when the upper cover 31 moves forward. During the extrusion process, the second side plate 43 and the first side plate 42 undergo elastic deformation so that the positioning convex block 44 enters the slot 46 and is opposite to the inner side surface of the second side plate 43. Until the upper cover 31 moves forward to a position where the positioning convex block 44 is opposite to the positioning groove 27 on the inner side surface of the second side plate 43, the second side plate 43 and the first side plate 42 elastically reset to make the positioning convex block 44 snap into the positioning groove 27 to form a lock. At this time, the upper slot 45 and the slot 46 are combined to form the above-mentioned assembly cavity 17 for installing the locking member 4; when disassembling the upper cover 31 and the lower cover 30, push the upper cover 31 backward or push the lower cover 30 forward to make the upper cover 31 and the lower cover 30 move relatively forward and backward. At this time, the positioning convex block 44 stuck in the positioning groove 27 forms extrusion with the positioning groove 27, and the first side plate 42 and the second side plate 43 undergo elastic deformation due to the extrusion, so that the positioning convex block 44 moves out of the positioning groove 27 and is opposite to the inner side surface of the second side plate 43. The upper cover 31 and the lower cover 30 continue to move relatively until the positioning convex block 44 moves out of the inner side surface of the second side plate 43, and the second side plate 43 and the first side plate 42 elastically reset, and then the bottom convex block can be pulled out of the slot 46 to complete the disassembly.

[0060] Two locking tongues 32 are provided at the front end of the locking member 4. There is a notch 36 between the front side plate 47 and the second side plates 43 on both sides. The two locking tongues 32 respectively extend out of the front side outside of the assembly cavity 17 from the notches 36 on both sides.

[0061] Preferably, anti-slip patterns 39 are provided on the bottom surface of the lower cover 30. When sliding the lower cover 30 to separate the upper cover 31 and the lower cover 30, fingers can press on the anti-slip patterns 39 to push the lower cover 30. The anti-slip patterns 39 are more convenient for the user to apply force and avoid slipping during pushing.

[0062] Preferably, the bottom protrusion 18 and the lower cover body 30 are combined to form an assembly box 33. A lower groove 11 is provided on the top surface of the cup lid body 2. When the flip cover 3 is pressed down to close the water outlet 29, the assembly box 33 is accommodated in the lower groove 11, making the overall structure of the cup lid more compact.
