The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0028] In the description of this utility model, "more than" means two or more, and "greater than," "less than," "exceeding," etc., are understood to exclude the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.
[0029] Reference Figures 1 to 3 A food preservation cup, the structure of which mainly includes an outer cup 100, an inner liner 200, a fixing ring 300 and a lid 400; specifically, the outer cup 100 is composed of two parts: a cup mouth 110 and a cup body 120. The cup body 120 is designed with a vacuum chamber 101 to effectively isolate external heat. The inner liner 200 is detachable and installed in the inner cavity of the cup body 120. The inner cavity 200 is filled with a filling cavity 201, which is pre-filled with a high-efficiency cold storage agent to maintain a low temperature environment.
[0030] When using this preservation cup, first place the inner liner 200 in the refrigerator to allow the refrigerant in the filling chamber 201 to fully store cold energy. Then, the user can directly pour breast milk into the inner liner 200, or place a bottle or sealed bag containing breast milk inside. During storage, the refrigerant will gradually release the stored cold energy, ensuring the breast milk remains in a low-temperature environment and effectively extending its preservation time. Simultaneously, place the inner liner 200 inside the cup body 120, and secure it to the outer cup 100 using the fixing ring 300. Then, install the cup lid 400, completely sealing the inner liner 200. In this way, the vacuum chamber 101 of the outer cup 100 effectively blocks heat transfer, allowing the inner liner 200 to maintain a low-temperature environment for an extended period, significantly improving the preservation effect of breast milk.
[0031] In addition, the inner cavity of the cup lid 400 can be vacuumed or filled with insulating material to further enhance the cold retention effect and ensure that breast milk stays fresh for a longer period of time.
[0032] Reference Figure 3 , 4 As shown in Figure 8, the fixing ring 300 includes an annular groove 310, which is used to insert the cup mouth 110. The annular groove 310 is composed of a first side wall 311 located on the outer side and a second groove wall 312 located on the inner side. The bottom of the second groove wall 312 is pressed against the edge of the top opening of the inner liner 200.
[0033] A second thread 111 is provided on the outer wall of the cup mouth 110, and a matching first thread 3111 is provided on the first side wall 311. Through the meshing connection of the first thread 3111 and the second thread 111, the fixing ring 300 can be firmly fixed at the cup mouth 110, the inner liner 200 can be pressed and fixed inside the outer cup 100, and the cup lid 400 can be installed.
[0034] When it is necessary to remove the inner liner 200 from the outer cup 100, simply rotate the retaining ring 300 to remove it from the cup opening 110, so that the inner liner 200 is no longer pressed and fixed by the retaining ring 300. The inner liner 200 can then be removed for cleaning or put back into the refrigerator to fully store cold energy.
[0035] When the inner liner 200, after being cleaned or fully stored for cold energy, is inserted into the outer cup 100, simply rotate the retaining ring 300 to install it at the cup opening 110. The retaining ring 300 will then press the inner liner 200 tightly into the outer cup 100, ensuring that the inner liner 200 will not detach from the outer cup 100.
[0036] Reference Figure 3 , 4As shown in Figures 7 and 8, in order to further enhance the sealing performance of the inner liner 200, prevent the leakage of cold energy, and extend the cold retention time of the inner liner 200, a first sealing ring 320 is installed at the lower part of the second groove wall 312. When the fixing ring 300 is installed on the cup mouth 110, the first sealing ring 320 is pressed against the edge of the top opening of the inner liner 200 to achieve a preliminary sealing effect.
[0037] Meanwhile, a second sealing ring 330 is installed in the annular groove 310. When the fixing ring 300 is installed on the cup mouth 110, the second sealing ring 330 fits tightly with the top surface of the cup mouth 110, thereby enhancing the sealing effect. At the same time, the double sealing of the first sealing ring 320 and the second sealing ring 330 significantly improves the sealing performance of the inner liner 200 and prevents the leakage of cold air.
[0038] To ensure the stability of the first sealing ring 320 during installation, a raised ring 3121 is provided at the lower part of the second groove wall 312, while the first sealing ring 320 is provided with a corresponding grooved ring 321.
[0039] When installing the first sealing ring 320, simply insert the convex ring 3121 into the groove ring 321 to securely fix the first sealing ring 320 to the lower part of the second groove wall 312, thus preventing the first sealing ring 320 from detaching and affecting the sealing effect.
[0040] During use, the inner liner 200 needs to be inserted into the cup body 120 of the outer cup 100. In order to allow the inner liner 200 to be easily removed and inserted, the outer diameter of the inner liner 200 will be slightly smaller than the inner diameter of the cup body 120 to reduce friction between the inner liner 200 and the cup body 120, or to avoid friction between the inner liner 200 and the cup body 120. This will create a certain gap between the outer wall of the inner liner 200 and the inner wall of the cup body 120, causing cold air to be lost through this gap.
[0041] To this end, a sealing protrusion 322 is provided on the side wall of the first sealing ring 320. The sealing protrusion 322 faces the inner wall of the cup mouth 110. When the fixing ring 300 is fixed at the cup mouth 110, the sealing protrusion 322 will tightly fit against the inner wall of the cup mouth 110, and the sealing protrusion 322 is located above the gap, thereby achieving the sealing of the gap between the outer wall of the inner liner 200 and the inner wall of the cup body 120 by the first sealing ring 320, effectively preventing the loss of cold energy and extending the preservation time.
[0042] Reference Figure 3 , 4As shown in Figure 8, in order to facilitate the installation of the cup lid 400, a third thread 340 is provided on the inner wall of the fixing ring 300, and a matching fourth thread 410 is provided on the outer wall of the cup lid 400. Through the meshing connection between the fourth thread 410 and the third thread 340, the cup lid 400 can be firmly installed on the top of the inner liner 200. The cup lid 400 completely seals the inner cavity of the inner liner 200, forming a sealed environment to prevent the leakage of cold air.
[0043] Reference Figure 5 , 6 The inner liner 200 includes an outer shell 210 and an inner shell 220. The inner shell 220 is installed inside the outer shell 210, and the top of the outer shell 210 is connected to the top of the inner shell 220, thereby forming a filling cavity 201 between the outer shell 210 and the inner shell 220. The filling cavity 201 is pre-filled with a high-efficiency cold storage agent. The cold storage agent can store cold energy in a low-temperature environment and release cold energy when storing breast milk, so that the breast milk is in a low-temperature environment, ensuring the freshness of the breast milk and preventing the breast milk from spoiling.
[0044] When storing breast milk in a container, it is inconvenient to remove the container from the inner liner 200. The inner liner 200 needs to be inverted to remove the container, which is very inconvenient.
[0045] Therefore, the inner shell 220 includes a flared portion 221 and a straight portion 222 from top to bottom. Since the diameter of the flared portion 221 is larger than the diameter of the straight portion 222, the upper part of the container can be easily clamped and removed by hand, making it convenient to remove the container placed in the inner liner 200.
[0046] Meanwhile, to ensure the sealing of the filling cavity 201, the top of the flared part 221 is connected to the top of the outer shell 210 to ensure the stability of the structure and the sealing of the filling cavity 201, so as to avoid leakage of the pre-filled high-efficiency refrigerant and affect the cooling effect of the inner liner 200.
[0047] To make it easier to carry the food storage cup, a handle 500 is specially installed, allowing users to easily carry the food storage cup. At the same time, both ends of the handle 500 can be detached and attached to the fixing ring 300, making it convenient for consumers to remove, replace or clean the handle 500.
