[0040] See also Figures 1 to 3 , Figures 1 to 3 The structural schematic diagram and cross-sectional schematic diagram of a mixing bottle cap and a container in an embodiment of the present application are respectively shown.

[0041] See also Figure 2 A mixing bottle cap provided in one embodiment of the present application includes an inner cap 1 and an inner sleeve 2. The mixing bottle cap is installed on a container to achieve storage and mixing of two liquids.

[0042] Specifically, the inner cover 1 includes a first accommodating cavity 12 for storing a first liquid, and an opening 11 is provided at the bottom of the first accommodating cavity 12. The inner sleeve 2 is relatively movably provided at one side of the bottom of the inner cover 1, and the inner sleeve 2 includes an infusion channel 25 that can communicate with the first accommodating cavity 12. When the inner cover 1 and the inner sleeve 2 are in a first position, the top of the inner sleeve 2 is sealed against the opening 11 to form a seal; when the inner cover 1 and the inner sleeve 2 are in a second position, the infusion channel 25 is communicated with the opening 11.

[0043] In this embodiment, the bottom of the inner cover 1 is mounted on the inner sleeve 2 , and the top of the inner sleeve 2 is embedded in the opening 11 at the bottom of the inner cover 1 to close the first accommodating chamber 12 so as to store the first liquid in the first accommodating chamber 12 .

[0044] In this embodiment, the container includes a bottle body 5 , the mixing bottle cap is installed on the bottle body 5 of the container, and the bottle body 5 stores the second liquid.

[0045] See also Figure 2 In the specific implementation process, when the inner cover 1 and the inner sleeve 2 are in the first position, that is, the inner cover 1 and the inner sleeve 2 do not move relative to each other, the top of the inner sleeve 2 is embedded in the opening 11 to block the opening 11 and form a seal.

[0046] See also Figure 3 When the inner cover 1 and the inner sleeve 2 are in the second position, that is, when an external force is applied to the mixing bottle cap, the inner cover 1 and the inner sleeve 2 are separated due to the relative movement between them, and then the infusion channel 25 is connected with the opening 11 and the first accommodating chamber 12, so that the first liquid in the first accommodating chamber 12 can flow out. When in use, the above-mentioned mixing bottle cap is usually installed on the bottle body 5, and the bottle body 5 is filled with the second liquid. After the inner cover 1 and the inner sleeve 2 move relative to each other, the first liquid flows into the bottle body 5 and mixes with the second liquid, thereby realizing the mixing process of the two liquids.

[0047] As described above, by designing the structure of the mixing bottle cap, the two liquids can be automatically mixed in the process of opening the bottle cap without the need for additional tools or complicated operations, which is conducive to simplifying the mixing operation and improving the user experience. In addition, the accuracy of the mixing ratio of the two liquids can be ensured by pre-packaging a certain proportion of the first liquid or the second liquid in the first accommodating cavity 12 or the bottle body 5.

[0048] In one embodiment, an opening 11 is provided at the bottom of the first accommodating cavity 12, and the opening 11 is used to seal with the inner sleeve 2 to form a closed space.

[0049] In one of the embodiments, the inner sleeve 2 is arranged on one side of the bottom of the inner cover 1, and the shape and size of the top thereof match the opening 11 of the inner cover 1, so that the outer peripheral side wall of the top of the inner sleeve 2 is in sealing contact with the inner wall of the inner cover 1, which is used to seal the above-mentioned opening 11, thereby forming a closed first accommodating cavity 12 together with the inner cover 1.

[0050] In one embodiment, the mixing bottle cap further comprises a first sealing member 10 , and the first sealing member 10 is sealingly disposed at the contact portion between the opening 11 and the top of the inner sleeve 2 .

[0051] Specifically, the first sealing member 10 is disposed around the inner wall of the opening 11 at the contact portion between the inner wall of the opening 11 and the top of the inner sleeve 2, forming an effective sealing barrier to ensure that the liquid in the first accommodating chamber 12 will not leak under normal storage conditions. Alternatively, the first sealing member 10 is disposed around the outer wall of the top of the inner sleeve 2.

[0052] In this embodiment, the first sealing member 10 is designed to be easy to fall off. When the inner cover 1 and the inner sleeve 2 move relative to each other and separate, the first sealing member 10 will automatically fall off, thereby allowing the first liquid to flow out and achieving a mixing operation.

[0053] In this embodiment, the top of the inner sleeve 2 is embedded in the opening 11 of the inner cover 1 to form a natural seal, thereby forming a closed first accommodating chamber 12. A first sealing member 10 is additionally provided at the contact portion between the inner sleeve 2 and the inner cover 1 to further improve the sealing performance of the two, and can be adaptively selected and adjusted according to specific usage requirements.

[0054] In this embodiment, the inner cover 1 and the inner sleeve 2 are connected by thread, snap or other detachable connection. When the liquid needs to be mixed, the user can separate the inner cover 1 from the inner sleeve 2 by rotating, pressing or other operations, and the relative movement of the inner cover 1 and the inner sleeve 2 causes the first sealing member 10 to fall off, so that the first liquid can flow out.

[0055] In this embodiment, liquid or powder can be stored in the first accommodating cavity 12, and liquid or powder can be stored in the bottle body 5. The items stored in the first accommodating cavity 12 and the bottle body 5 can be adaptively adjusted according to specific usage requirements.

In some embodiments, the inner periphery of the inner sleeve 2 is provided with an embedded portion, the embedded portion is provided in the open opening 11, and the periphery of the embedded portion of the inner sleeve 2 is provided with an infusion channel, which is connected to the first accommodating cavity to achieve the outflow of the first liquid.

[0057] In one embodiment, the embedded portion includes a first section 21 and a second section 22. The first section 21 is arranged in a direction perpendicular to the axial direction of the inner sleeve 2, that is, it is arranged horizontally perpendicular to the axial direction of the inner sleeve 2. The first section 21 is embedded in the opening 11 to achieve the closure of the first accommodating cavity 12.

[0058] In one embodiment, the second section 22 is connected to the first section 21, and the second section is arranged along the axial direction of the inner sleeve 2, that is, vertically arranged along the axial direction of the inner sleeve 2, and the second section 22 and the first section 21 are embedded in the opening 11. The outer wall of the second section 22 is in sealing contact with the inner wall of the opening 11, further improving the sealing effect.

[0059] In one embodiment, the inner sleeve 2 includes a third section 23, which is arranged on the periphery of the embedded part of the inner sleeve 2, and is connected to the second section 22. There are gaps between multiple third sections 23 to form an infusion channel 25, so as to realize the connection between the inner sleeve 2 and the inner cover 1, and realize the first liquid flowing out from the first accommodating cavity 12 through the infusion channel 25.

[0060] In the specific implementation process, the inner cover 1 is threadedly matched with the inner sleeve 2. When the bottle cap rotates, due to the relative rotational movement of the inner cover 1 and the inner sleeve 2, the first seal 10 automatically falls off, so that the first liquid in the first accommodating chamber 12 is released and flows into the infusion channel 25.

[0061] In one embodiment, the second section 22 of the inner sleeve 2 is arranged at a certain angle to the first section 21, the second section 22 extends downward from the extended end of the first section 21, the outer wall of the second section 22 is in close contact with the inner wall of the opening 11 of the inner cover 1, and the first sealing member 10 is arranged at the contact portion between the two, that is, it is arranged circumferentially around the outer wall of the second section 22 or around the inner wall of the opening 11 to form a sealing barrier. In this embodiment, the angle between the second section 22 and the first section 21 can be a right angle, an acute angle or an obtuse angle, and can be adaptively adjusted according to specific usage requirements, which will not be described in detail here.

[0062] In one embodiment, the third segments 23 extend downward from the second segment 22, bend at the end to form a certain angle, and then extend toward the outside of the second segment 22, that is, extend upward. In addition, there are gaps 26 between the third segments 23 to form an infusion channel 25.

[0063] In this embodiment, the diameter and shape of the gaps 26 between the plurality of third sections 23 can be adaptively adjusted according to specific usage requirements.

[0064] As described above, the three-stage structural design of the inner sleeve 2 realizes the release and mixing of the first liquid, thereby improving the user experience. In addition, the overall structure of the inner sleeve 2 is simple, which helps to reduce the manufacturing cost.

[0065] Combination Figure 2 , Figure 7 As shown, Figure 2 , Figure 7 They are respectively a cross-sectional schematic diagram of a mixing bottle cap and a container provided in an embodiment of the present application and a structural schematic diagram of a sealing cap 4. In some embodiments, the mixing bottle cap further comprises a sealing cap 4, and the sealing cap 4 is sealedly disposed on the top of the inner cap 1.

[0066] Specifically, an opening 11 is also provided on the top of the inner cover 1. The sealing cover 4 is sealed at the opening 11 on the top of the inner cover 1, and together with the inner cover 1 forms a closed first accommodating chamber 12 for storing a first liquid so as to mix it with a second liquid in the bottle body 5 during subsequent operations, while preventing the first liquid from leaking from the top of the inner cover 1 to ensure sealing.

[0067] In one embodiment, the mixing bottle cap further includes a second sealing member 40 , and the second sealing member 40 is disposed at the contact portion between the sealing cap 4 and the inner cap 1 .

[0068] Specifically, a second sealing member 40 is provided at the contact portion between the sealing cover 4 and the inner cover 1. The second sealing member 40 is arranged circumferentially around the side wall of the sealing cover 4, that is, located on the contact surface between the outer peripheral side wall of the sealing cover 4 and the inner wall of the inner cover 1. In this embodiment, the second sealing member 40 can be made of elastic material, such as silicone, rubber, etc., to ensure good sealing performance.

[0069] In this embodiment, the sealing cover 4 and the inner cover 1 are in contact with each other to form a natural seal to prevent liquid leakage. Alternatively, a second sealing member 40 is added to the contact portion between the sealing cover 4 and the inner cover 1 to further improve the sealing effect, which can be adaptively adjusted according to specific usage requirements.

[0072] In one embodiment, the bottom of the inner plug 3 is disposed in the bottle body 5, and the top of the inner plug 3 is matched with the inner sleeve 2. The inner plug 3 is provided with a through cavity 31 connected with the infusion channel 25, which is used to allow the first liquid in the first accommodating chamber 12 to flow into the bottle body 5 through the infusion channel 25 and the cavity 31 to mix with the second liquid after the mixing bottle cap is opened.

[0073] In the specific implementation process, when two liquids need to be mixed, the user rotates the mixing bottle cap to place the inner cover 1 and the inner sleeve 2 in the second position, thereby separating the inner cover 1 from the inner sleeve 2. At this time, the first liquid in the first accommodating chamber 12 flows into the bottle body 5 through the infusion channel 25 of the inner sleeve 2 and the cavity 31 of the inner plug 3, and mixes with the second liquid.

[0074] In this embodiment, the infusion channel 25 may include one or more openings to ensure that the liquid can flow out smoothly.

[0075] In this embodiment, the bottle body 5 may be made of glass, plastic or other materials suitable for liquid storage, and its shape and size may be adjusted according to actual needs.

[0076] As described above, a container with a mixing bottle cap can effectively separate and store two liquids and mix them instantly, which improves the convenience of the container and the user experience. At the same time, there is no need to use two separate containers for mixing, which simplifies the mixing operation and reduces the cost of use.
