Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, specifically a thermos cup with a novel sealing structure. Background Technology

[0002] A thermos is a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm.

[0003] To ensure a good seal and insulation, a sealing ring is usually installed inside the lid of a thermos. The sealing ring also prevents water from spilling out from the gap between the body and the lid. The thermos usually contains water at a relatively high temperature. After the water cools down, the air pressure inside the thermos decreases, creating a negative pressure state. The sealing ring and the opening at the top of the body can easily stick together due to the air pressure, causing the sealing ring to be pulled out of the lid and affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a novel thermos cup with a sealing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel thermos cup with a sealing structure, comprising:

[0006] The thermos body, lid, upper vent, sealing gasket, corresponding connecting hole, and lower vent hole;

[0007] The cup lid is detachably connected to the upper opening of the insulated cup body. The sealing gasket is embedded in the upper inner wall of the cup lid. The sealing gasket is a hollow ring. The corresponding connecting hole and the lower vent hole are respectively opened on the upper and lower outer walls of the sealing gasket, and the positions of the corresponding connecting hole and the lower vent hole are staggered.

[0008] The upper vent is longitudinally formed on the upper surface of the cup lid, and the upper vent penetrates the cup lid and corresponds to the position of the corresponding connecting hole.

[0009] Preferably, the outer wall of the upper opening of the thermos cup body is provided with an external thread, and the inner wall of the cup lid is provided with an internal thread that engages with the external thread.

[0010] Preferably, the cup lid includes an outer decorative layer and an insulating plastic layer disposed on the inner wall of the outer decorative layer.

[0011] Preferably, an insertion sealing block is formed on the upper side of the inner cavity of the cup lid, and the insertion sealing block is inserted into the upper opening of the insulated cup body.

[0012] Preferably, a sealing groove is formed between the outer periphery of the inserted sealing block and the upper end of the inner wall of the cup lid, and the sealing gasket is embedded in the sealing groove.

[0013] Preferably, the upper ends of the sealing embedding groove are provided with limiting grooves, and the upper parts of the inner and outer walls of the sealing gasket are provided with limiting rings that match the limiting grooves.

[0014] Preferably, the sealing gasket and the limiting ring are both made of rubber, and the sealing gasket and the limiting ring are integrally formed.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When in use, after the connection between the thermos body and the lid is tightened, the pressure from the upper opening of the thermos body causes the lower vent hole of the sealing gasket to be blocked. At the same time, the air inside the sealing gasket is squeezed out from the corresponding connecting hole and the upper vent hole. At this time, the corresponding connecting hole is sealed by the lower layer of the sealing gasket. The lid and sealing gasket separate the upper opening of the thermos body from the outside, achieving a good insulation and sealing effect.

[0017] Furthermore, when the lid is removed, the sealing gasket allows air to enter simultaneously, making it less likely to detach from the lid. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: a novel sealed thermos cup, comprising: a thermos cup body 1, a cup lid 3, an upper vent 11, a sealing gasket 8, a corresponding connecting hole 10, and a lower vent hole 12;

[0026] The cup lid 3 is detachably connected to the upper opening of the insulated cup body 1. The sealing gasket 8 is embedded in the upper inner wall of the cup lid 3. The sealing gasket 8 is hollow and annular. The corresponding connecting hole 10 and the lower vent hole 12 are respectively opened on the upper and lower outer walls of the sealing gasket 8, and the positions of the corresponding connecting hole 10 and the lower vent hole 12 are staggered. The upper vent hole 11 is longitudinally opened on the upper surface of the cup lid 3, and the upper vent hole 11 penetrates the cup lid 3 and corresponds to the position of the corresponding connecting hole 10. An insertion sealing block 5 is formed on the upper side of the inner cavity of the cup lid 3. The insertion sealing block 5 is inserted into the upper opening of the insulated cup body 1. A sealing embedding groove 6 is formed between the outer periphery of the insertion sealing block 5 and the upper end of the inner wall of the cup lid 3, and the sealing gasket 8 is embedded in the sealing embedding groove 6.

[0027] Analysis of the above content: When using it, follow... Figure 2 In this manner, the sealing gasket 8 is embedded into the upper inner side of the cup lid 3, so that the corresponding connecting hole 10 is connected to the upper vent hole 11 (since the size of the corresponding connecting hole 10 is relatively larger than that of the upper vent hole 11, the connection between the corresponding connecting hole 10 and the upper vent hole 11 is relatively simple, and the sealing gasket 8 is tightly connected to the cup lid 3, so that when the cup lid 3 rotates on the insulated cup body 1, the sealing gasket 8 will not rotate relative to the cup lid 3 due to friction. If necessary, adhesive can be used to bond and fix the sealing gasket 8). This also prevents the sealing gasket 8 from falling off the cup lid 3. The sealing gasket 8 is clamped in the sealing embedding groove 6, so that the sealing gasket 8 is squeezed and clamped by the sealing embedding groove 6 and is not easy to fall off.

[0028] When the thermos body 1 and the lid 3 are connected, the upper opening of the thermos body 1 pushes into the sealing groove 6 and squeezes the sealing gasket 8. At this time, the lower vent hole 12 first contacts the upper opening of the thermos body 1 and is sealed. As the upper opening of the thermos body 1 moves upward, it squeezes the sealing gasket 8, causing the sealing gasket 8 to be compressed and deformed, and the air in the sealing gasket 8 is discharged through the corresponding connecting hole 10 and the upper vent hole 11. Since the corresponding connecting hole 10 and the lower vent hole 12 are staggered, after the upper and lower side walls of the sealing gasket 8 are compressed and attached, the corresponding connecting hole 10 and the lower vent hole 12 are both sealed.

[0029] When the lid 3 is removed, the lid 3 rises relative to the insulated cup body 1, and the sealing gasket 8 expands. External air can enter the sealing gasket 8 through the upper vent 11 and the corresponding connecting hole 10, while air enters through the lower vent 12. Air enters between the insulated cup body 1 and the sealing gasket 8, and the insulated cup body 1 will not pull the sealing gasket 8 down from the lid 3.

[0030] Because the upper vent 11 has a small diameter, it is not easy for dust to enter. Also, because the corresponding connecting hole 10 and the lower detachment vent 12 are staggered, even if a small amount of dust enters, it is not easy to reach the lower detachment vent 12. Furthermore, the cup is frequently cleaned, so even if dust enters, it will be cleaned. Therefore, the insulated cup body 1 here is a conventional insulated cup body.

[0031] Example 2:

[0032] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: an external thread 2 is provided on the outer wall of the upper opening of the thermos cup body 1, and an internal thread 4 is provided on the inner wall of the cup lid 3 to cooperate with the external thread 2.

[0033] Analysis of the above content: The use of threaded connection is a conventional connection method, which will not be elaborated here.

[0034] Example 3:

[0035] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: the cup lid 3 includes an outer decorative layer and a heat-insulating plastic layer disposed on the inner wall of the outer decorative layer.

[0036] Analysis of the above content shows that the thermal insulation plastic layer has excellent thermal insulation effect.

[0037] Example 4:

[0038] Please see Figure 1-3This utility model provides a technical solution based on Embodiment 1: Limiting grooves 7 are formed at both ends of the upper part of the sealing embedding groove 6, and limiting rings 9 matching the limiting grooves 7 are provided on the upper parts of the inner and outer walls of the sealing gasket 8. Both the sealing gasket 8 and the limiting rings 9 are made of rubber, and are integrally formed together.

[0039] Analysis of the above content: The limiting ring 9 is embedded in the limiting groove 7, making it difficult for the sealing gasket 8 and the limiting ring 9 to detach from the sealing embedding groove 6 and the limiting groove 7.
