[0002] The existing thermos cup structure, especially the flip-top or flip-top type, generally has a small hole for exhaust (also known as pressure relief) on the cup cover, and when the cover is closed, the small hole is blocked by a sealing column on the cover to ensure the tightness of the cup body. The purpose of this is that when the thermos cup is filled with hot water, the cup body will expand and form a different air pressure from the outside. If there is no exhaust hole, the hot water in the cup body will spray out due to uneven air pressure when the drinking spout is opened.

[0003] In the above common structures, the exhaust holes are generally exposed to the outside when drinking, which are easily contaminated, and an additional sealing column is required to seal the exhaust holes. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present application provides an insulated coffee cup, which aims to simplify the existing common structure on the basis of meeting the existing functions, and also provides a new feasible solution for the design of the insulated cup cover.

DETAILED DESCRIPTION

[0026] Reference Figure 1-8 As shown, it is a specific embodiment of the present application: a heat preservation coffee cup, which can be used to hold hot drinks such as coffee, milk tea, hot tea, etc. The heat preservation coffee cup mainly includes a cup body 1 and a cup cover 2 detachably combined with the cup body 1. In this embodiment, the cup body 1 has a heat preservation function, specifically, the cup body includes an outer layer 11, an inner layer 12 and a vacuum layer 13 placed therebetween, and the vacuum layer 13 is used as a heat insulation medium layer to provide heat preservation; the cup cover 2 and the cup body 1 can be connected by threads, or other methods can be used. For example, in this embodiment, the cup cover 2 includes a side edge 21 and a lower edge 22, and the outer diameter of the side edge 21 is set to be at least larger than the inner diameter of the cup body 1, and the outer diameter of the lower edge 22 is set to be at least smaller than the inner diameter of the cup body 1. A sealing ring 4 is sleeved on the lower edge 22, and the sealing ring 4 is sealed between the cup body 1 and the lower edge 22; when the cup cover 2 is combined with the cup body 1, the cup cover 2 is pressed against the cup body 1 by the interference deformation of the sealing ring 4.

[0027] Furthermore, the cup cover 2 is provided with a drinking port 23 and an exhaust hole 24 connected to the inner cavity of the cup body 1. The drinking port 23 provides a drinking function, which can be directly in contact with the mouth for direct drinking, or a straw can be inserted to form a straw-style drinking; and the exhaust hole 24 provides pressure relief for the drinking port 23 when it is opened, so as to balance the pressure inside and outside the cup body 1 and prevent high-temperature hot water from spraying directly from the drinking port 23.

[0028] In this embodiment, a connecting pipe 3 is provided, and the connecting pipe 3 has a through passage 31. One end of the connecting pipe 3 is sealed and connected to the exhaust hole 24, and the other end of the connecting pipe 3 is provided with a sealing plug 32. The sealing plug 32 can be selectively sealed on the drinking port 23, that is, when the water needs to be kept warm when not drinking, the sealing plug 32 blocks the drinking port 23; when drinking is needed, the sealing plug 32 is removed from the drinking port 23, and at this time, the high-pressure hot air inside the cup body 1 will simultaneously communicate with the outside through the connecting pipe 3 to release the pressure.

[0029] As a preferred embodiment of the connecting tube 3, the sealing plug 32 includes a convex edge 321. When the sealing plug 32 is sealed on the drinking port 23, the convex edge 321 is pressed against the upper edge of the drinking port 23. At the same time, the connecting tube 3 and the sealing plug 32 are an integrated structure, and the whole is made of soft rubber. In this way, the convex edge 321 can provide a pinching area for the sealing plug 32 when it is pulled out, so as to avoid directly pulling the tube body 33 of the connecting tube 3 and causing it to break. At the same time, the convex edge 321 can also play a role of further sealing and decoration.

[0030] In order to drink more conveniently, the cup cover 2 is provided with a step 5 which at least partially protrudes upward, and the drinking port 23 is arranged at the step 5. In this way, a protruding drinking portion is formed, which facilitates the user's mouth to better contact with the drinking port to prevent leakage.

[0031] In order to fix the connecting tube 3 when drinking, to prevent the connecting tube 3 from touching the mouth or face of a person and causing discomfort, a fixing part for fixing the connecting tube 3 is also provided on the cup cover 2. The present application provides the following three different implementations for the fixing part.

[0032] like Figure 4 As shown, as a first embodiment of the fixing portion: the step 5 is an annular boss formed on the cup cover 2, and the fixing portion is a slot 61 arranged on the annular boss, and the slot 61 is arranged on the side opposite to the drinking port 23. When drinking, the tube body 33 of the connecting tube 3 is limited by the slot 61.

[0033] like Figure 5 As shown, as a second embodiment of the fixing portion: the step 5 is a partial boss formed on the cup cover 2, and the fixing portion includes two clamping strips 62 extending vertically from the top surface of the cup cover 2, and the area between the clamping strips 62 forms a second clamping groove 63, through which the tube body 33 of the connecting tube 3 when drinking is fixed.

[0034] like Figure 6 As shown, as a third embodiment of the fixing part: the step 5 is a partial boss formed on the cup cover 2, and the fixing part includes a clamping column 64 extending vertically from the top surface of the cup cover 2, and the clamping column 64 is hollow and is provided with an open groove 641 on one side, and an exhaust groove 65 communicating with the open groove 641 is provided on the top surface of the cup cover 2 on the side of the open groove 641. When drinking, the cavity 322 inside the sealing plug part 32 communicates with the through-type channel 31, and the cavity 322 is sealed on the clamping column 64. At the same time, the inner cavity of the cup body 1, the connecting pipe 3, the clamping column 64, and the exhaust groove 65 are sequentially connected and communicated with the outside to ensure that the exhaust state is continuous.

[0035] Based on the above embodiment, in order to facilitate the rotation of the connecting pipe 3 and facilitate the clamping, as shown in FIG. Figure 2 and 3 As shown, the end of the connecting pipe 3 connected to the exhaust hole 24 is provided with an annular groove 34 , and the annular groove 34 is sealingly clamped on the wall of the exhaust hole 24 .

[0036] As another way to use this application, Figure 8 As shown, the cup cover 2 is removed from the cup body 1, and a disposable coffee cup 7 made of paper or plastic is placed into the cup body 1, thereby achieving the effect of keeping warm the coffee beverages to be taken out or packaged.

[0037] The above is only a preferred embodiment of the present application and does not impose any form of limitation on the present application. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present application shall fall within the scope of protection of the present application.
