[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0071] As shown in the attached figure, the dual-chamber container bottle provided in this embodiment mainly includes a bottle body 10, a valve assembly 20, an operating component, and a bottle cap assembly 40.

[0072] First, please refer to Figure 1 and Figure 2 The bottle body 10 will be described.

[0073] The bottle body 10 has a first chamber (not shown) and a second chamber (not shown) that are physically isolated from each other, which can be used to hold two different liquids (such as wines of different strengths). The neck of the bottle body 10 has an integrated bottle neck structure, which includes a first outlet channel 13 and a second outlet channel 14. The first outlet channel 13 communicates with the first chamber, and the second outlet channel 14 communicates with the second chamber. The first outlet channel 13 is located inside the second outlet channel 14. In this preferred embodiment, the first outlet channel 13 and the second outlet channel 14 are coaxially arranged, forming a double-layered tubular structure, which makes the structure compact and facilitates the installation of subsequent valve assemblies.

[0074] Next, please refer to Figure 3A , 3B The valve assembly 20 is described in detail using 4A, 4B, 5A, 5B, 6A, and 6B.

[0075] The valve assembly 20 is the core of the system for dispensing two liquids on demand. It mainly consists of a valve seat 21 and a valve core 22.

[0076] The valve seat 21 is a stationary component, which is connected to the first outlet 13 and the second outlet 14 of the bottle body 10. In this embodiment, the valve seat 21 includes a central sleeve 211 and an outer peripheral sleeve 212.

[0077] The central sleeve 211 is inserted into and seals against the inner wall of the first outlet channel 13. The internal space of the central sleeve 211 defines a valve chamber 23, in which the valve core 22 is housed. The bottom of the central sleeve 211 has a first inlet 214a, which directly connects to the first outlet channel 13. One or more second inlets 214b are provided on the side wall of the central sleeve 211.

[0078] To achieve precise positioning, an annular limiting part 25 (e.g., a limiting step or flange) is provided on the outer wall of the central sleeve 211. When the valve seat 21 is installed, the limiting part 25 abuts against the upper end face of the first outlet channel 13, thereby achieving precise axial positioning of the central sleeve 211. The second inlet 214b is preferably located above the limiting part 25.

[0079] The outer peripheral sleeve 212 is arranged annularly outside the central sleeve 211 and is sealed to the inner wall of the second outlet channel 14. In this way, an annular flow channel communicating with the second outlet channel 14 is formed between the side wall of the central sleeve 211 and the inner wall of the outer peripheral sleeve 212. This annular flow channel is connected to the valve chamber 23 through the second inlet 214b on the side wall of the central sleeve 211.

[0080] To securely fix the valve seat 21 to the bottle body 10 and prevent it from rotating during use, this embodiment also includes a fixing sleeve 213. The fixing sleeve 213 is circumferentially disposed outside the outer peripheral sleeve 212, and its inner wall is provided with a first anti-rotation structure and a first axial limiting structure between it and the outer wall of the second outlet channel 14. As an example, the first anti-rotation structure includes an axially extending first rib 141 disposed on the outer wall of the second outlet channel 14 and an axially extending first groove 213a disposed on the inner wall of the fixing sleeve 213. The engagement of the first rib 141 and the first groove 213a ensures that the entire valve seat 21 will not rotate relative to the bottle body 10. The first axial limiting structure includes a circumferentially extending first boss 142 disposed on the outer wall of the second outlet channel 14 and a circumferentially extending first buckle 213b disposed on the inner wall of the fixing sleeve 213. The first buckle 213b engages with the first boss 142.

[0081] The valve core 22 is a rotating component, rotatably housed within the valve cavity 23 of the valve seat 21. The valve core 22 has an axially extending main outlet channel 221 running through it. Two independent outlets are located on its bottom and sidewall: a first outlet 222a and a second outlet 222b, both of which communicate with the main outlet channel 221.

[0082] To achieve precise rotational positioning and a good user experience, the outer wall of the valve core 22 is provided with one or more radially protruding limiting protrusions 223, while the top inner wall of the valve seat 21 is provided with a limiting recess 24 that matches the limiting protrusions 223. The valve core is circumferentially positioned by the limiting protrusions 223 and the limiting recess 24.

[0083] The operating element facilitates user-driven rotation of the valve core 22. In this embodiment, the operating element is specifically an outer sleeve 30. The inner side of the outer sleeve 30 is connected to the upper end of the valve core 22 via a non-circular fit (e.g., spline or D-shaped surface), ensuring that the valve core 22 rotates synchronously when the user rotates the outer sleeve 30. The upper end of the outer sleeve 30 is integrally formed or connected to a unified liquid outlet 31. The upper end of the valve core 22 is inserted into the outer sleeve 30, and the main liquid outlet channel 221 of the valve core 22 is aligned with and connected to the unified liquid outlet 31.

[0084] To make rotation smoother and the structure more stable, this embodiment also includes a middle sleeve 60. The middle sleeve 60 is fixedly fitted around the outer periphery of the fixed sleeve 213, while the lower section of the outer sleeve 30 is rotatably fitted around the outer side of the middle sleeve 60, forming a stable rotational support structure. A second anti-rotation structure is provided between the inner wall of the middle sleeve 60 and the outer wall of the fixed sleeve, and a second axial limiting structure is provided between the inner wall of the middle sleeve 60 and the outer wall of the second outlet channel. As an example, the second anti-rotation structure includes an axially extending second rib 213c provided on the outer wall of the fixed sleeve 213 and an axially extending second groove 61 provided on the inner wall of the middle sleeve 60, the second rib 213c engaging with the second groove 61. The second axial limiting structure includes a circumferentially extending second boss 143 provided on the outer wall of the second outlet channel 14 and a circumferentially extending second buckle 62 provided on the inner wall of the middle sleeve 60, the second buckle 62 engaging with the second boss 143.

[0085] A third axial limiting mechanism is provided between the outer wall of the middle sleeve 60 and the inner wall of the outer sleeve 30. As an example, the third axial limiting mechanism includes a third groove 63 extending circumferentially on the outer wall of the middle sleeve 60 and a third buckle 32 on the inner wall of the outer sleeve 30. The third buckle 32 cooperates with the third groove 63.

[0086] Finally, to keep the contents clean and prevent leakage when not in use, a cap assembly 40 is provided, which can be screwed on or snapped on to detachably seal the unified liquid outlet 31. The cap assembly 40 is prior art and will not be described in detail here.

[0087] The working principle of this utility model is as follows:

[0088] The valve core 22 of this invention can be switched to at least two working positions.

[0089] When in the first working position (see Figure 1 When the user rotates the outer sleeve 30, the first outlet 222a on the valve core 22 is precisely aligned with the first inlet 214a on the valve seat 21. At this time, the solid wall of the valve core 22 completely seals the second inlet 214b. When the user pours or squeezes the bottle, the liquid in the first chamber will flow out along the following path: first chamber -> first outlet 13 -> first inlet 214a -> first outlet 222a -> main outlet channel 221 -> unified outlet 31. At this time, the passage to the second chamber is cut off.

[0090] When in the second working position: the user continues to rotate the outer sleeve 30 to the next position, so that the second outlet 222b on the valve core 22 is precisely aligned with the second inlet 214b on the valve seat 21. At this time, the solid wall of the valve core 22 closes the first inlet 214a. When the user pours or squeezes the bottle, the liquid in the second chamber will flow out along the following path: second chamber -> second outlet 14 -> ... -> second inlet 214b -> second outlet 222b -> main outlet channel 221 -> unified outlet 31. At this time, the passage of the first chamber is cut off.

[0091] In summary, this utility model, through its ingeniously designed coaxial bottle mouth and rotary valve assembly consisting of a valve seat and a valve core, allows for convenient and reliable selective dispensing of different liquids from a single outlet into two chambers simply by rotating the operating component. It features a compact structure, a good user experience, and high practical value.

[0092] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
