[0043] like Figures 1 to 6 As shown, this embodiment provides a multifunctional milk storage container, comprising:

[0044] The inner bottle 10 and the outer bottle 20 are both hollow structures with one end open. The inner bottle 10 is used to hold liquid, and at least a portion of the inner bottle 10 is inserted into the cavity of the outer bottle 20;

[0045] A bottle cap 30 is provided on the opening of the inner bottle 10;

[0046] The adapter 40 is a hollow structure with openings at both ends. The adapter 40 is sleeved on the inner bottle 10. The adapter 40 is respectively provided with a first connecting part 41, a second connecting part 42, and a third connecting part 43 that are detachably connected to the inner bottle 10, the outer bottle 20 and the bottle cap 30. The third connecting part 43 is also configured to be adaptable and connected to a milk warmer or a breast pump. When the bottle cap 30 is taken off, the inner bottle 10 can be connected to the milk warmer or the breast pump through the adapter 40.

[0047] The adapter 40 is a hollow shell structure at both ends. The adapter 40 can be detachably connected to the inner bottle 10, the outer bottle 20, and the bottle cap 30. Specifically, the adapter 40 is provided with a first connecting portion 41.

[0049] The adapter 40 is also provided with a third connecting portion 43, and the bottle cap 30 can be used to seal the opening of the inner bottle 10. When the bottle cap 30 is covered on the opening of the inner bottle 10, the third connecting portion 43 on the adapter 40 can be detachably connected to the bottle cap 30 to fix the bottle cap 30 on the adapter 40, thereby sealing the opening of the inner bottle 10.

[0050] It should be noted that the first connecting portion 41 and the inner bottle 10, the second connecting portion 42 and the outer bottle 20, and the third connecting portion 43 and the bottle cap 30 can be detachably connected by one or a combination of snap-fit, threaded, press-fit, or other connection methods. For example, the first connecting portion 41 is a threaded structure, and the inner bottle 10 is provided with a threaded structure that is threadedly connected to the first connecting portion 41, and the first connecting portion 41 is threadedly connected to the inner bottle 10.

[0051] Furthermore, the third connecting portion 43 can be connected not only to the bottle cap 30 but also to a breast pump or milk warmer. For example, the third connecting portion 43 is a threaded structure, and the bottle cap 30, the breast pump, or the milk warmer are all provided with a threaded structure that can be threadedly connected to the third connecting portion 43. When the bottle cap 30 is removed from the adapter and the third connecting portion 43 is connected to the breast pump, the breast pump directly transfers the sucked milk to the liquid storage chamber of the inner bottle 10. When the third connecting portion 43 is connected to the milk warmer, the milk warmer can heat and maintain the temperature of the liquid stored in the inner bottle 10.

[0052] Furthermore, the liquid contained in the inner bottle 10 is not limited to milk, but can also be other liquids such as beverages and wine.

[0053] The multifunctional milk storage container in the above embodiment includes an inner bottle 10, an outer bottle 20, a bottle cap 30 and an adapter 40. The adapter 40 is provided with a first connection part 41, a second connection part 42 and a third connection part 43. The adapter 40 is a hollow structure with two ends open. The adapter 40 is sleeved on the inner bottle 10 and the adapter 40 is detachably connected to the inner bottle 10 through the first connection part 41; the inner bottle 10 is partially inserted into the cavity formed inside the outer bottle 20 and the adapter 40 is detachably connected to the inner bottle 10 through the second connection part 42. The adapter 40 is detachably connected to the outer bottle 20; the adapter 40 can also be detachably connected to the bottle cap 30 or a breast pump or a milk warmer via the third connection portion 43. When the third connection portion 43 is connected to the bottle cap 30, the bottle cap 30 is used to seal the opening of the inner bottle 10; when the third connection portion 43 is connected to the breast pump, the breast pump transfers the sucked milk to the liquid storage chamber of the inner bottle 10 through the adapter 40; when the third connection portion 43 is connected to the milk warmer, the milk warmer can heat and keep the liquid in the inner bottle 10 warm. The present application utilizes the mutual cooperation of the adapter 40 with the inner bottle 10, the outer bottle 20, and the bottle cap 30 to enable the milk storage container to adapt to the entire process from sucking and bagging milk to keeping the milk refrigerated and heating and keeping it warm. This eliminates the need for additional adapter accessories, simplifies operation, and thus improves the user experience.

[0054] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the first connecting portion 41 is a threaded structure, and the inner bottle 10 is provided with a fourth connecting portion 110 threadedly connected to the first connecting portion 41.

[0055] The above embodiment further defines that the first connection portion 41 and the fourth connection portion 110 are both threaded structures, and the adapter 40 and the inner bottle 10 are threadedly connected via the first connection portion 41 and the fourth connection portion 110, thereby achieving detachable connection between the adapter 40 and the inner bottle 10, so that the inner bottle 10 can be used in combination with adapters 40 of corresponding specifications according to different sizes of outer bottles 20, bottle caps 30, breast pumps or milk warmers, without the need to replace the inner bottle 10. In addition, the adapter 40 and the inner bottle 10 are fixed by threaded connection, which is easy to assemble and disassemble and has high reliability.

[0056] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines that: a first sealing member 51 is provided between the adapter 40 and the inner bottle 10 .

[0057] The above embodiment further defines that a first seal 51 is provided between the adapter 40 and the inner bottle 10. The first seal 51 can seal the gap between the adapter 40 and the inner bottle 10 to prevent the liquid stored in the inner bottle 10 from leaking from the gap between the adapter 40 and the inner bottle 10.

[0058] Among them, the first connecting part 41 is distributed on the cavity wall of the adapter 40, and a first annular limit platform 410 is provided on the cavity wall of the adapter 40. The first sealing member 51 is an annular sealing ring structure, and the first sealing member 51 is provided on the first annular limit platform 410. As the inner bottle 10 is threadedly connected to the adapter 40, the bottle mouth of the inner bottle 10 gradually abuts against the side of the first sealing member 51 away from the first annular limit platform 410 and gradually adheres to it, thereby realizing the gap between the sealing adapter 40 and the inner bottle 10.

[0059] like Figures 1 to 3 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second connecting portion 42 is a threaded structure, and the outer bottle 20 is provided with a fifth connecting portion 210 threadedly connected to the second connecting portion 42.

[0060] In the above embodiment, it is further defined that the second connection portion 42 and the fifth connection portion 210 are both threaded structures, and the adapter 40 and the outer bottle 20 are threadedly connected via the second connection portion 42 and the fifth connection portion 210, thereby realizing that the adapter 40 is detachable relative to the outer bottle 20. Based on the detachability between the adapter 40 and the outer bottle 20, hot water or ice cubes can be poured into the cavity of the outer bottle 20 to heat or cool the liquid stored in the inner bottle 10 accordingly.

[0061] The second connection portion 42 can be distributed on the surface or inner sidewall of the adapter 40. For example, the second connection portion 42 is distributed on the surface of the adapter 40, and the diameter of the opening of the outer bottle 20 is not only larger than the diameter of the inner bottle 10, but also larger than the diameter of the adapter 40 where the second connection portion 42 is distributed. Part of the inner bottle 10 and part of the adapter 40 are inserted into the cavity of the outer bottle 20, and then the second connection portion 42 is threadedly connected to the fifth connection portion 210.

[0062] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the third connecting portion 43 is a threaded structure, a sixth connecting portion 310 threadedly connected to the third connecting portion 43 is provided on the bottle cap 30, and a milk warmer or a breast pump can be threadedly connected to the third connecting portion 43.

[0063] The above embodiment further defines that the third connection portion 43 and the sixth connection portion 310 are both threaded structures, and the adapter 40 and the bottle cap 30 are threadedly connected via the third connection portion 43 and the sixth connection portion 310, thereby realizing that the adapter 40 is detachable relative to the bottle cap 30. Based on the detachability between the adapter 40 and the bottle cap 30, when the bottle cap 30 is assembled on the adapter 40, the bottle cap 30 can seal the opening of the inner bottle 10 to prevent leakage of the liquid stored in the inner bottle 10; when the bottle cap 30 is removed from the adapter 40, the adapter 40 can be connected to a milk warmer or a breast pump through the third connection portion 43.

[0064] It should be noted that the above-mentioned milk warmer or breast pump is provided with a structure that can be threadedly connected to the third connecting part 43. When the third connecting part 43 is threadedly connected to the milk warmer, the milk warmer is connected to the liquid storage chamber of the inner bottle 10 through the adapter 40; similarly, when the third connecting part 43 is threadedly connected to the breast pump, the breast pump is connected to the liquid storage chamber of the inner bottle 10 through the adapter 40.

[0065] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the diameter of the end of the adapter 40 where the first connection portion 41 is distributed is smaller than the diameter of the end of the adapter 40 where the third connection portion 43 is distributed.

[0066] In the above embodiment, it is further defined that the diameter of the connection between the adapter 40 and the outer bottle 20 is larger than the diameter of the connection between the adapter 40 and the bottle cap 30. Based on the above design, it is convenient to distinguish the direction of the adapter 40 during the product assembly process of the milk storage container, thereby improving the assembly effect. In addition, the diameter of the connection between the adapter 40 and the bottle cap 30 is smaller, which can adapt to the connection diameter of most breast pumps or milk warmers on the market. There is no need to modify the existing breast pumps or milk warmers, thereby reducing the cost of use.

[0067] It should be noted that the first connection portion 41 may be distributed between the second connection portion 42 and the third connection portion 43 .

[0068] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines that a second sealing member 52 is provided between the adapter 40 and the outer bottle 20 .

[0069] The above embodiment further defines a second seal 52 between the adapter 40 and the outer bottle 20. The second seal 52 can seal the gap between the adapter 40 and the outer bottle 20 to prevent the liquid stored in the outer bottle 20 from leaking from the gap between the adapter 40 and the outer bottle 20.

[0070] Among them, the second connecting part 42 is distributed on the surface of the adapter 40, a second annular limit platform 420 is provided on the surface of the adapter 40, and the second sealing member 52 is an annular sealing ring structure, and the second sealing member 52 is provided on the second annular limit platform 420. As the outer bottle 20 is threadedly connected to the adapter 40, the bottle mouth of the outer bottle 20 gradually abuts against the side of the second sealing member 52 away from the second annular limit platform 420 and gradually adheres to it, thereby achieving a gap between the sealing adapter 40 and the outer bottle 20.

[0071] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiment, this embodiment further defines: the bottle cap 30 includes a cap body 31 and a water sealing valve 32 connected to the cap body 31, and the side of the water sealing valve 32 opposite to the opening of the inner bottle 10 is made of soft material, and the water sealing valve 32 is used to seal the opening of the inner bottle 10.

[0072] In the above embodiment, it is further specified that the material of the side of the water sealing valve 32 facing the opening of the inner bottle 10 is a soft material. When the cap body 31 is connected and assembled with the third connecting portion 43 on the adapter 40, the end of the water sealing valve 32 made of the soft material blocks the opening of the inner bottle 10 to prevent leakage of the liquid stored in the inner bottle 10.

[0073] The soft material may be one of food-grade silicone rubber, EPDM rubber, fluororubber, and polytetrafluoroethylene.

[0074] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: the water sealing valve 32 includes a valve body 321 and a transition connector 322, the valve body 321 is a sealing cover structure sleeved on the transition connector 322, the valve body 321 is made of soft material, the diameter of the valve body 321 gradually decreases towards the opening of the inner bottle 10, the valve body 321 is interference fit with the adapter 40 or the opening of the inner bottle 10, and the transition connector 322 abuts against the cap body 31.

[0075] The above embodiment further defines that during the process of threaded connection between the cap body 31 and the adapter 40, the valve body 321 portion gradually abuts against the cavity wall of the adapter 40 or the bottle mouth of the inner bottle 10 and forms an interference fit, thereby achieving sealing of the opening of the inner bottle 10 and preventing leakage of the liquid stored in the inner bottle 10.

[0076] The valve body 321 is a sealing cover structure whose diameter gradually decreases toward the opening of the inner bottle 10. The valve body 321 is sleeved on the transition connector 322. When the cap body 31 is threadedly connected to the third connecting portion 43 of the adapter 40, the transition connector 322 is squeezed by the cap body 31, causing the valve body 321 to gradually extend toward the opening of the inner bottle 10, so that the valve body 321 abuts the cavity wall of the adapter 40 or the bottle mouth of the inner bottle 10. For example, the valve body 321 abuts the first annular stop 410 on the adapter 40. As the threaded connection progresses, the valve body 321 and the first annular stop 410 form an interference fit, thereby sealing the opening of the inner bottle 10. It should be noted that the valve body 321 can also extend into the liquid storage cavity of the inner bottle 10, abutting and forming an interference fit with the bottle mouth of the inner bottle 10.

[0077] In addition, the transition connector 322 can be a columnar structure provided with a slot 301. Accordingly, a protruding column 311 is provided on the cap body 31, and the protruding column 311 can be inserted into the slot 301 and abut against the bottom of the slot 301. As the cap body 31 and the adapter 40 are threadedly connected, the protruding column 311 pushes the transition connector 322 toward the opening direction of the inner bottle 10, thereby realizing the abutment between the valve body 321 and the first annular limit platform 410 of the adapter 40 or the bottle mouth of the inner bottle 10.

[0078] In addition to the features of the above embodiment, this embodiment further defines that: the outer bottle 20 is a vacuum bottle.

[0079] The above embodiment further defines that the outer bottle 20 adopts vacuum technology. Based on the above design, the vacuum layer of the outer bottle 20 can reduce the heat transfer between the liquid stored in the inner bottle 10 and the outside air, thereby improving the thermal insulation effect.

[0080] like Figure 2 As shown, in addition to the features of the above embodiment, this embodiment further defines that: a gap is left between the outer wall of the inner bottle 10 located in the cavity of the outer bottle 20 and the inner wall of the outer bottle 20, and the gap is used to fill the insulation liquid.

[0081] The above embodiment further defines a gap between the outer bottle 20 and the inner bottle 10 , and the user can pour hot water or ice cubes into the cavity of the outer bottle 20 to heat or cool the liquid stored in the inner bottle 10 accordingly.

[0082] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of this utility model patent shall be determined by the appended claims.
