[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0025] Reference Figures 1 to 6 This embodiment provides a food preservation cup for storing and carrying foods that require low-temperature preservation (such as dairy products, breast milk, etc.).
[0026] like Figure 1 , Figure 2 and Figure 6 As shown, the food preservation cup of this embodiment includes a cup body 1, a detachable cup lid 6, and a separable inner liner 2 inserted into the cup body 1. The cup lid 6 is located at the opening of the cup body 1 to close one side of the opening of the inner liner 2. Of course, the cup lid 6 may also be provided with a rotatable handle 61.
[0027] The bottom of the cup body 1, away from its opening, is provided with a receiving cavity 11. The receiving cavity 11 is provided with a first cooling box 3 for storing cooling materials. The first cooling box 3 is used to cool the inner liner 2 located inside the cup body 1, so as to preserve the food inside the inner liner 2.
[0028] In this embodiment, the inner liner 2 and the first cooling box 3 are spaced apart to prevent mechanical interference between the inner liner 2 and the first cooling box 3 inside the cup body 1, and also to prevent the inner liner 2 from being unable to be fully inserted into the cup body 1.
[0029] like Figure 3 As shown, the outer peripheral surface of the first cooling box 3 is provided with a coolant inlet / outlet 32 to enable the coolant to be loaded into or removed from the first cooling box 3.
[0030] When needed, first put the coolant (such as ice water) into the first cooling box 3 through the coolant inlet 32, then put the first cooling box 3 into the receiving cavity 11 located at the bottom, then insert the inner liner 2 into the cup body 1, and then put the cup lid 6 on.
[0031] The inner liner 2 located inside the cup body 1 is cooled by the first cooling box 3 to ensure that the temperature inside the inner liner 2 remains in a low temperature range for a longer period of time, thereby keeping the food inside the inner liner 2 fresh for a longer period of time without spoilage or deterioration.
[0032] In another preferred embodiment, such as Figure 1As shown, a vacuum insulation cavity 12 is provided inside the wall of the cup body 1 to form a vacuum cup body 1 structure, which can further insulate the heat. Of course, in other embodiments, the cup body 1 may not need the vacuum insulation cavity 12, as long as the cup body 1 and the inner liner 2 are not in direct contact with each other.
[0033] Further preferred, such as Figure 3 As shown, the first cooling box 3 has concave surfaces 31 at its upper and lower ends in the axial direction to further prevent mechanical interference. Of course, in other embodiments, the concave surface 31 may also be provided at one end of the first cooling box 3.
[0034] Further preferred, such as Figure 1 As shown, the circumferential inner wall of the cup body 1 and the outer circumferential surface of the inner liner 2 are spaced apart and together form a circumferential cavity 4 that connects to the receiving cavity 11.
[0035] Two second cooling boxes 5 for storing coolant are provided inside the circumferential cavity 4. Each second cooling box 5 can be detachably inserted into the circumferential cavity 4, and when in use, the two second cooling boxes 5 are arranged around the outer circumferential surface of the inner liner 2.
[0036] In this specific embodiment, the inner liner 2 has a circular cross-sectional shape; therefore, the cup body 1 and the lid 6 are both circular. Of course, in other embodiments, the shape of the food preservation cup can also be elliptical, square, or polygonal, etc.
[0037] like Figure 1 As shown, a limiting wall 13 is provided between the receiving cavity 11 and the circumferential cavity 4. The cup body 1 includes a first cup body 14, a second cup body 15, and a transition section 16 connecting the first cup body 14 and the second cup body 15. The inner wall of the first cup body 14 and the outer wall of the inner liner 2 together form the circumferential cavity 4. The inner cavity of the second cup body 15 is the receiving cavity 11. The transition section 16 is inclined. At this time, the inner wall of the transition section 16 is the limiting wall 13, so as to ensure that the inner diameter of the circumferential cavity 4 on the side close to the receiving cavity 11 gradually decreases. Therefore, the second cooling box 5 can be prevented from falling into the receiving cavity 11 by the limiting wall 13, that is, the second cooling box 5 is limited in the circumferential cavity 4.
[0038] Also, such as Figure 4 As shown, the second cooling box 5 has an arc-shaped groove 51 on the side facing the inner liner 2 to match the outer circumferential surface of the inner liner 2, and to make the two second cooling boxes 5 surround the outer circumferential surface of the inner liner 2 with a gap.
[0039] Of course, in other embodiments, the number of second cooling boxes 5 can also be one or more, with multiple second cooling boxes 5 arranged in a ring at equal intervals in the inner liner 2.
[0040] Further preferred, such as Figure 1 and Figure 5 As shown, a connecting seat 7 is provided between the cup lid 6 and the inner liner 2. The connecting seat 7 has a first connecting wall 72 and a second connecting wall 73 that protrude outwards at the lower end of the cup body 1. The center of the connecting seat 7 is provided with a channel 71 that axially penetrates its inner and outer surfaces. When the cup lid 6 is closed, the first connecting wall 72 and the second connecting wall 73 both extend into the circumferential cavity 4.
[0041] The first connecting wall 72 and the second connecting wall 73 are annular and spaced apart from each other. The first connecting wall 72 surrounds the second connecting wall 73, and the second connecting wall 73 surrounds the opening of the channel 71. The outer peripheral surface of the first connecting wall 72 is provided with an external thread to match the internal thread of the cup body 1 so as to screw the connecting seat 7 to the cup body 1. The inner peripheral wall of the second connecting wall 73 is provided with an internal thread to screw the external thread of the inner liner 2. When the cup lid 6 is closed, it can close the opening of the circumferential cavity 4 to prevent heat transfer.
[0042] More preferably, the upper end of the connecting seat 7 facing the cup lid 6 has a third connecting wall 74 that extends outward, the third connecting wall 74 is annular, and the third connecting wall 74 surrounds the channel opening of the channel 71.
[0043] The outer peripheral surface of the third connecting wall 74 is provided with an external thread to match the internal thread of the cup lid 6 so that the cup lid 6 can be detachably screwed to the connecting seat 7.
[0044] When needed, first place the first cooling box 3 into the receiving cavity 11 located at the bottom, then insert the inner liner 2 into the cup body 1, then insert the two second cooling boxes 5 into the circumferential cavity 4 between the inner liner 2 and the cup body 1 respectively, then screw the first connecting wall 72 and the second connecting wall 73 of the connecting seat 7 to the cup body 1 and the inner liner 2 respectively, and finally screw the cup lid 6 to the third connecting wall 74 of the screw seat.
[0045] By screwing the connecting seat 7 and the inner liner 2 together to form the inner liner 2 assembly, and screwing the connecting seat 7 of the inner liner 2 assembly to the cup body 1, the inner liner 2 assembly and the cup body 1 are integrally connected. Therefore, by simply opening the cup lid 6, the channel 71 that connects to the inner cavity of the inner liner 2 can be exposed, and the food inside the inner liner 2 can be quickly taken out.
[0046] In addition, when the food preservation cup of this embodiment does not require the first cooling box 3 and the second cooling box 5, that is, when the first cooling box 3 and the second cooling box 5 are no longer placed in the cup body 1, the inner cavity of the inner liner 2 can be used as a loading space for cooling substances or food. The storage cavity formed by the corresponding receiving cavity 11 and the circumferential cavity 4 can also be used as a loading space for food or cooling substances. For example, cooling substances are placed in the inner liner 2 and food is placed in the storage cavity, or food is placed in the inner liner 2 and cooling substances are placed in the storage cavity.
[0047] Of course, in other embodiments, the cup lid 6, the inner liner 2, and the connecting seat 7 can also be connected to each other using a snap-fit structure.
[0048] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
