Detailed Implementation

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] This embodiment mainly describes a thermos cup designed to prevent accidental opening, as detailed below:

[0031] like Figures 1 to 9As shown, a thermos cup designed to prevent accidental opening includes a cup body 1, a cup lid, and a connecting cover 2 disposed between the cup body 1 and the cup lid for connecting the cup lid to the cup body 1. The connecting cover 2 is threadedly connected to the cup body 1. The connecting cover 2 has a protrusion 21, on which a drinking spout 22 communicating with the cup body 1 and a straw spout 23 are provided. The lid body 3 includes a main lid body 31, a first flip cover 32, and a second flip cover 33. The main lid body 31 is fixedly sleeved on the outside of the connecting cover 2. Specifically, the connecting cover 2 has a vertically arranged elastic protrusion 24 on its side wall, and the main lid body 31 has a vertically arranged elastic protrusion 24 on its inner wall that cooperates with the elastic protrusion 24. The elastic protrusion 24 of the connecting cover 2 slides from the bottom of the vertical groove 315 of the main cover 31 into the vertical groove 315 and is interference-fitted with the vertical groove 315 to snap the main cover 31 onto the connecting cover 2. In order to enhance the stability of the main cover 31 and the connecting cover 2 and prevent the main cover 31 from slipping off the connecting cover 2, the side wall of the connecting cover 2 is provided with an elastic protrusion ring 25 along the circumferential direction, and the side wall of the main cover 31 is provided with an annular groove 316 along the circumferential direction to cooperate with the elastic protrusion ring 25. When the main cover 31 is fitted onto the connecting cover 2, the elastic protrusion ring 25 is snapped into the annular groove 316 and is interference-fitted with the annular groove 316. The first flip cover 32 is rotatably connected to the main cover 31 via a rotating shaft. The first flip cover 32 has protruding connecting walls 325 on both sides. The second flip cover 33 has hinge shafts on both side walls and is rotatably connected between the two connecting walls 325 via the hinge shafts. An elastic block 324 is fixedly provided on the top surface of the first flip cover 32 away from the rotatable connection. The inner wall of the second flip cover 33 has a limiting groove 331 that cooperates with the elastic block 324. The second flip cover 33 rotates to cover the silicone nozzle 41, and the elastic block 324 cooperates with the limiting groove 331 to fix the second flip cover 33 onto the first flip cover 32. A handle 8 is also rotatably mounted on the hinge shaft and fitted onto the outside of the second flip cover 33. Two elastic protrusions 332, with a spacing adapted to the handle 8, are vertically provided on both side walls of the second flip cover 33. The handle 8 can rotate between the two elastic protrusions 332 and be limited by them.

[0032] like Figure 6 , Figure 8 Figure 9As shown, the main cover 31 has a through hole 311 for the boss 21 to pass through. The upper end of the boss 21 passes through the through hole 311, causing the drinking spout 22 and the straw spout 23 to protrude between the main cover 31 and the first flip cover 32. The first flip cover 32 has a silicone component 4 corresponding to the drinking spout 22 and the straw spout 23. The silicone component 4 is used to seal the drinking spout 22 and the straw spout 23 to achieve long-term heat preservation of the cup body 1. The specific connection structure between the silicone component 4 and the first flip cover 32 is as follows: the first flip cover 32 has a connection hole 322 corresponding to the mounting hole. The silicone component 4 is fitted into the mounting hole. The silicone component 4 includes a silicone spout 41 and a sealing ring 42. The upper end of the silicone spout 41 passes through the mounting hole so that the spout is located above the first flip cover 32. For convenient drinking, the silicone spout 41 is positioned upwards on the side away from the rotating hinge on the upper side of the first flip cover 32. The silicone nozzle 41 is tilted and its middle part is tightly fitted to the wall of the mounting hole. The lower end of the silicone nozzle 41 is located under the first flip cover 32. When the first flip cover 32 is closed on the main cover 31, the lower end of the silicone nozzle 41 is connected to and tightly fitted with the straw opening 23 to achieve a sealed connection between the nozzle and the straw opening 23. The bottom of the first flip cover 32 is provided with an annular sleeve 323 that extends vertically downward along the edge of the mounting hole and abuts against the boss 21. The annular sleeve 323 is used to cover the drinking mouth 22 and the straw opening 23 inside the annular sleeve 323. The sealing ring 42 is fitted on the bottom of the annular sleeve 323. The sealing ring 42 can seal the connection between the boss 21 and the annular sleeve 323. When the first flip cover 32 is closed on the main cover 31, the lower end of the sealing ring 42 is tightly abutted against the top surface of the boss 21 and covers the drinking mouth 22 to seal the drinking mouth 22.

[0033] Figure 4 , Figure 5 and Figure 9 As shown, the connecting hole 322 is a stepped hole. The silicone nozzle 41 is provided with a support platform 411 that abuts against the step of the stepped hole. The bottom wall and side wall of the support platform 411 are in close contact with the step and side wall of the stepped hole, respectively, which improves the sealing performance of the cover 3. The arrangement of the support platform 411, the stepped hole, the annular sleeve 323 and the sealing ring 42 forms a sealed space that covers the drinking spout 22, thus sealing the drinking spout 22.

[0034] like Figure 7 As shown, the main cover 31 has a through hole 317 on the side wall away from the rotating connection side, such as... Figure 8 As shown, the side wall of the connecting cover 2 is provided with a sliding groove 26 corresponding to the through hole 317, such as Figure 6As shown, when the main cover 31 is connected to the connecting cover 2, the through hole 311 and the sliding groove 26 form an installation groove 5 extending from the outside of the side wall of the main cover 31 to the side wall of the connecting cover 2. The installation groove 5 is provided with a button 6 that moves in the radial direction of the main cover 31 when subjected to lateral force and resets when the force is lost. The button 6 is provided with a hook groove 61. The first flip cover 32 is provided with a first hook 321 that can be hooked on the hook groove 61. When the first hook 321 is hooked on the hook groove 61, the first flip cover 32 is closed on the main cover 31, and the drinking spout 22 is closed. When the button 6 is pressed laterally along the installation groove 5, the button 6 slides in the installation groove 5. When the hook groove 61 gradually moves away from the first hook 321 until it is disengaged from the first hook 321, the first flip cover 32 is opened.

[0035] Specifically, to avoid interference between the first flip cover 32 and the main cover 31 when the first flip cover 32 is closed on the main cover 31, the top surface of the main cover 31 near the mounting groove 5 has a notch 314 that extends downward and communicates with the mounting groove 5, and the first hook 321 is inserted into the hook groove 61 from the notch 314.

[0036] Specifically, to prevent accidental pressing of button 6 during transport, which could cause water inside the cup 1 to flow out from the drinking spout 22 and straw spout 23 and result in burns, the main cover 31 is provided with a limiting member 7 that can slide into the mounting groove 5 to restrict the radial movement of button 6. The limiting member 7 is an arc-shaped slider 71, which is equipped with a toggle block 72. The inner side wall of the main cover 31 is provided with an arc-shaped groove 312 arranged circumferentially. The arc-shaped groove 312 is used to install the arc-shaped slider 71. The arc length of the arc-shaped groove 312 is greater than the arc length of the arc-shaped slider 71. The arc-shaped groove 312 is connected to the mounting groove 5, and the bottom part of the arc-shaped groove 312 penetrates through the side wall of the main cover 31. The arc-shaped sliding hole 313 allows the actuating block 72 to pass through. When the actuating block 72 is pushed towards the button 6, the actuating block 72 can slide along the arc-shaped sliding hole 313, causing one end of the arc-shaped slider 71 to slide into the mounting groove 5 and abut against the inner wall of the button 6 to restrict the radial movement of the button 6. If the button 6 is accidentally pressed during use, the button 6 cannot be pushed to slide in the mounting groove 5 due to the obstruction of the arc-shaped slider 71, so that the hook groove 61 cannot disengage from the first hook 321. This prevents the first flip cover 32 from being opened by mistake, improves the safety of the cup, and avoids the accidental scalding caused by water flowing out of the drinking spout 22 and straw spout 23 in the cup body 1 due to accidental opening.

[0037] Specifically, the mounting groove 5 is a two-stage stepped groove, including a first-stage stepped groove 51 and a second-stage stepped groove 52. The button 6 is a two-stage stepped button adapted to the stepped groove, including a first-stage stepped button 64 and a second-stage stepped button 65. First hooks 511 are provided on both sides of the first-stage stepped groove 51. Second hooks 62, which hook onto the first hooks 511, are provided on both sides of the first-stage stepped button 64. The button 6 is slidably connected to the mounting groove 5 through the cooperation of the second hooks 62 and the first hooks 511. A return spring 63 is provided in the first-stage stepped groove 51. One end of the return spring 63 abuts against the bottom of the first-stage stepped groove 51, and the other end abuts against the inner wall of the first-stage stepped button 64. There is a gap between the inner wall of the second-stage stepped button 65 and the second-stage stepped groove 52 that is adapted to the arc-shaped slider 71. The second-stage stepped groove 52 is connected to the arc-shaped sliding groove 312, and the arc-shaped slider 71 can slide from the arc-shaped sliding groove 312 into the gap. The gap provides space for the sliding of button 6 and also serves as a space to accommodate the arc-shaped slider 71.

[0038] In the above, the first flip cover 32 is used to cover the drinking spout 22 and the straw opening 23, and the second flip cover 33 is used to cover the silicone spout 41. When the first flip cover 32 is opened and the second flip cover 33 is closed, the drinking spout 22 and the straw opening 23 are opened, and the water in the cup body 1 is poured out from the drinking spout 22 or drunk directly through the drinking spout 22. When the first flip cover 32 is closed and the second flip cover 33 is opened, the silicone spout 41 is opened, and water can be drunk directly through the silicone spout 41.
