[0040] In this embodiment, the hot / cold cup includes an outer container 10 , an inner container 20 , a medium container 30 , and a heat storage medium (not shown).

[0041] The inner container 20 is removably contained in the outer container 10. The medium container 30 is removably contained in the outer container 10 and is located between the outer container 10 and the inner container 20. The medium container 30 defines a storage space R. The storage space R contains a heat storage medium.

[0042] The embodiment of the present application sets up a hot and cold cup including an outer container 10, an inner container 20, a medium container 30 and a heat storage medium. The inner container 20 can be removed and accommodated in the outer container 10, and the medium container 30 can be removed and accommodated in the outer container 10 and is located between the outer container 10 and the inner container 20. A accommodating space R is provided in the medium container 30, and the heat storage medium is accommodated in the accommodating space R, which can improve the efficiency and uniformity of heat conduction. Through testing, ice cubes were placed between the inner container and the outer container as a comparative example. The ice cubes and the medium container were placed in a refrigerator for pre-cooling, and then respectively placed in the gap between the inner and outer containers. The initial cooling efficiency of the solution using the medium container in the present application was significantly higher than that of the solution using ice cubes in the comparative example, and the uniformity of cooling in different parts was significantly higher than that of the comparative example.

[0043] It should be understood that the hot and cold cups of the present invention are not limited to cooling the liquid in the inner container 20; they can also heat the liquid in the inner container 20. For example, the medium container 30 can be placed in a refrigerator for a period of time before being placed in the outer container 10 to freeze the liquid in the inner container 20. In another use case, the medium container 30 can be placed in boiling water for a period of time before being placed in the outer container 10 to heat the liquid in the inner container 20. In some use cases, two medium containers 30 can be configured and used interchangeably, with the two medium containers 30 containing different heat storage media, one for heat storage and the other for cold storage. Of course, a single medium container 30 can also be configured to achieve both heat and cold storage. The heat storage medium is typically a liquid, solid, or gel with a high specific heat capacity. For example, in one embodiment, the heat storage medium can be a cryogel, an aqueous solution of ethylene glycol or propylene glycol, or simply water, although this embodiment is not limited to this.

[0044] Optionally, in this embodiment, the medium container 30 is cylindrical and surrounds the inner container 20 when the inner container 20 is accommodated in the outer container 10. In some embodiments, the medium container may include a bottom wall, thereby further improving the efficiency of heat and cold conduction.

[0045] Optionally, the medium container 30 includes a sealing member 31 and a cylindrical main body 32 . A notch H is formed at the end of the main body 32 . An injection port F is provided at the notch H. The sealing member 31 is disposed at the injection port F and is used to seal the injection port F.

[0046] In one embodiment, the hot / cold cup further includes a connector 40 having a first coupling structure 41, and the outer container 10 is provided with a second coupling structure 11 corresponding to the first coupling structure 41. The first coupling structure 41 can be a threaded structure provided on the connector 40, and the second coupling structure 11 can be a threaded structure provided on the outer container 10 and matching the threaded structure on the connector 40. For example, one of the first coupling structure 41 and the second coupling structure 11 can be an internal thread, and the other can be an external thread. In other embodiments, the first coupling structure 41 and the second coupling structure 11 can be mated in other ways, such as a snap fit, an interference fit, etc., and this embodiment of the present application is not limited thereto.

[0047] Optionally, the first coupling structure 41 is disposed on the inner wall of the connector 40, and the second coupling structure 11 is disposed on the outer wall of the outer container 10. By disposing the second coupling structure 11 on the outer wall of the outer container 10, it is possible to prevent interference with the removal and insertion of the inner container 20 and the medium container 30 from the outer container 10. For example, the first coupling structure 41 may be an internally threaded structure disposed on the inner wall of the connector 40, and the second coupling structure 11 may be an externally threaded structure disposed on the outer wall of the outer container 10. The connector 40 and the outer container 10 are mated via a threaded connection.

[0048] In one embodiment, the hot / cold cup may further include an upper cover 50. One end of the connector 40 is used to connect to the outer container 10, and the other end of the connector 40 is used to connect to the upper cover 50. The diameter of the end of the connector 40 used to connect to the outer container 10 is larger than the diameter of the end of the connector 40 used to connect to the upper cover 50. In this way, the diameter of the outer container 10 can be set to be larger, which makes it easier to place the inner container 20 and the medium container 30 into the outer container 10. In order to facilitate the unscrewing of the connector 40 from the outer container 10, the diameter of the end of the connector 40 connected to the upper cover 50 is set to be larger than the diameter of the end of the connector 40 connected to the outer container 10. In this way, a person can hold the connector 40 and screw it, while ensuring that the outer container 10 has a sufficient diameter to allow the inner container 20 and the medium container 30 to be taken out and put in.

[0049] Optionally, the upper cover 50 is provided with a third coupling structure 51, and the connector 40 is provided with a fourth coupling structure 42. The upper cover 50 and the connector 40 are connected and detached from each other through the cooperation of the third coupling structure 51 and the fourth coupling structure 42. The third coupling structure 51 and the fourth coupling structure 42 can be matching threaded structures. For example, the third coupling structure 51 is an internal threaded structure provided on the inner wall of the upper cover 50, and the fourth coupling structure 42 can be an external threaded structure provided on the outer wall of the connector 40. By setting the diameter of the end of the connector 40 connected to the upper cover 50 to be larger than the diameter of the end of the connector 40 connected to the outer container 10, it is possible to ensure that a person can hold the upper cover 50 for tightening while ensuring that the outer container 10 has a sufficient diameter to allow the inner container 20 and the medium container 30 to be taken out and put in.

[0050] In one embodiment, the cup may further include a handle 60 connected to the connector 40. The handle 60 allows the user to lift the cup. The handle 60 also facilitates tightening or loosening the threaded connection between the connector 40 and the outer container 10 by gripping the handle 60.

[0051] In one embodiment, there are at least two inner containers 20, which are stacked and placed within the outer container 10. Providing at least two inner containers 10 allows milk produced at different time periods to be stored separately, such as milk extracted from a breast pump at different time periods. This prevents milk from different time periods from mixing together, as milk stored for a long time may affect the quality of fresh milk and cause it to taint and spoil. In this embodiment, the number of inner containers 20 is preferably two. In other embodiments, the number of inner containers 20 may also be one, three, or more, and this embodiment of the present application is not limited thereto.

[0052] In one embodiment, the bottom of the inner container 20 is provided with a recessed structure A. By providing the recessed structure A, when at least two inner containers 20 are stacked in the outer container 10, the top of the lower inner container 20 can be at least partially accommodated in the recessed structure A of the upper inner container 20. This saves space and ensures the stability of the stacked inner containers 20.

[0053] Optionally, the inner container 20 is provided with a connection structure that mates with a breast pump or pacifier. For example, the inner container includes a bottle body 21 and a bottle cap 22, which are threadedly connected. The threads on the bottle body 21 can mate with the threads of the milk outlet in the three-way structure (negative pressure interface, milk suction channel, and milk outlet) of a breast pump, so that milk sucked by the breast pump can be directly sucked into the inner container 20. For another example, the threads on the bottle body 21 can be threadedly connected to a cap with a pacifier, so that after the bottle body 21 of the inner container 20 is connected to the pacifier, it can be directly fed to the child.

[0054] In one embodiment, a vacuum insulation cavity is opened inside the side wall and / or bottom wall of the outer container 10, and the vacuum insulation cavity is vacuum, thereby isolating the temperature transfer between the hot and cold cup and the outside world.

[0055] In one embodiment, the upper cover 50 includes a cover shell 52 and a thermal insulation material 53 filled within the cover shell 52, thereby reducing temperature exchange between the interior of the outer container 10 and the outside. After being connected to the connector 40, the upper cover 50 abuts against the upper surface of the inner container 20. The upper cover 50 does not contact or couple with the connector 40.

[0056] The embodiment of the present application provides a hot and cold cup including an outer container, an inner container, a medium container and a heat storage medium. The inner container can be removably accommodated in the outer container, the medium container can be removably accommodated in the outer container and is located between the outer container and the inner container, and a accommodating space is provided in the medium container, and the heat storage medium is accommodated in the accommodating space, which can improve the efficiency and uniformity of heat conduction.
