[0055] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0056] like Figures 1-5 As shown, the multi-bottle combination packaging structure of this utility model is a cosmetic multi-bottle combination packaging structure, which includes a bottle group 10, a bottle mouth lock 20, a dispensing nozzle 30, a shoulder cover 40, an outer cap 50, and an outer frame 60. The bottle group 10 includes two or more interlocking bottle bodies. In this example, continuing as... Figure 1 and Figure 6 As shown, specifically, there are two adjacent bottle bodies, namely the first bottle body 11 and the second bottle body 12, which are connected to each other by a male and female fastener 13. Figure 1 and Figure 6As shown, the first bottle body 11 has a first concave surface 11a and a first convex surface 11b on its fastening surface, and the second bottle body 12 has a second concave surface 12a and a second convex surface 12b on its fastening surface. The male and female fasteners 13 include a male fastener 13a and a female fastener 13b. In this example, the male fastener 13a is a ring-shaped protrusion, which is respectively installed on the first convex surface 11b of the first bottle body 11 and the second convex surface 12b of the second bottle body 12. The female fastener 13b is a ring-shaped hole that can be pressed and fastened to the ring-shaped protrusion, which is respectively installed on the first concave surface 11a of the first bottle body 11 and the second concave surface 12a of the second bottle body 12. By interlocking and fitting the female buckle 13b on the first concave surface 11a with the male buckle 13a on the second convex surface 12b, and by interlocking and fitting the male buckle 13a on the first convex surface 11b with the female buckle 13b on the second concave surface 12a, the combination and connection of the first bottle body 11 and the second bottle body 12 can be achieved. At the same time, since the fastening surfaces of the adjacent bottles are both concave and convex, the outer contour of the bottle group 10 formed by the combination and connection is more neat and beautiful, which makes it easier to pick up or repackage.

[0057] To further ensure the tightness and stability of the bottle assembly 10 formed by the combined connection, bottle neck locks 20 are locked onto the bottle necks 14 of all bottles in the bottle assembly 10. Furthermore, the bottle neck locks 20 possess a certain elastic tension, naturally remaining open, meaning they can be freely closed or opened manually. Specifically, for example... Figure 7 The illustration shows an example of a bottle neck lock 20. The bottle neck lock 20 has an interconnecting end 21, an opening end 25, and a first clamping arm 22 and a second clamping arm 23 respectively connected to the interconnecting end 21 and disposed opposite to each other. One end of the first clamping arm 22 and the second clamping arm 23 are integrally connected to form the interconnecting end 21, and the other end of the first clamping arm 22 and the other end of the second clamping arm 23 are interlocked to form the opening end 25. Specifically, the first clamping arm 22 and the second clamping arm 23 are interlocked at the opening end 25 by a first connecting member 24. The first connecting member 24 includes a first snap-fit ​​24a and a first slot 24b that are interlocked. In one example, the first clamping arm 22 has a first snap-fit ​​24a on its inner sidewall at the opening end 25, and the second clamping arm 23 has a first slot 24b on its outer sidewall at the opening end 25. In another example, the second clamping arm 23 has a first latch 24a on its outer side wall at the opening 25, and the first clamping arm 22 has a first slot 24b on its inner side wall at the opening 25. In yet another preferred example, such as... Figure 6As shown, the first clamping arm 22 has a first buckle 24a and a first slot 24b on its inner sidewall at the opening 25. The second clamping arm 23 also has a corresponding first slot 24b and a first buckle 24a on its outer sidewall at the opening 25. The first buckle 24a on the first clamping arm 22 and the first slot 24b on the second clamping arm 23 interlock, and the first slot 24b on the first clamping arm 22 and the first buckle 24a on the second clamping arm 23 are connected by an interlocking mechanism. Alternatively, in another example of a bottle neck yoke 20, such as... Figures 10-12 As shown, the bottle neck yoke 20 has a detachable first clamping arm 22, a second clamping arm 23, and a first locking block 61 and a second locking block 62 symmetrically fixed on the outer frame 60. One end of the first clamping arm 22 and one end of the second clamping arm 23 are connected to the first locking block 61, and the other ends of the first clamping arm 22 and the second clamping arm 23 are connected to the second locking block 62 via a fourth connecting member. Similarly, a portion of the fourth connecting member is located on the outer walls of both ends of the first clamping arm 22 and the second clamping arm 23, while the other portion is located on the inner walls of the first locking block 61 and the second locking block 62. The portion and the other portion of the fourth connecting member are mutually connected. Specifically, the fourth connecting member includes a longitudinal buckle 26a and a longitudinal groove 26b that are mutually connected; the longitudinal buckle 26a can be located on the outer walls of the first clamping arm 22 and the second clamping arm 23, while the longitudinal groove 26b is located on the inner walls of the first locking block 61 and the second locking block 62. Alternatively, the longitudinal slot 26b can be provided on the outer side wall of the first clamping arm 22 and the second clamping arm 23, while the longitudinal buckle 26a can be provided on the inner side wall of the first locking block 61 and the second locking block 62. Of course, the longitudinal buckle 26a and the longitudinal slot 26b can also be provided on the outer side wall of the first clamping arm 22 and the second clamping arm 23 at the same time. In this case, the longitudinal slot 26b and the longitudinal buckle 26a are correspondingly provided on the inner side wall of the first locking block 61 and the second locking block 62, thereby realizing the mutual engagement of the first clamping arm 22 and the second clamping arm 23.

[0058] for Figure 7 The bottle neck yoke 20 shown in the example has a certain elastic tension, so the elastic buckle structure formed by the first buckle 24a and the first slot 24b can be freely fastened or opened by human force. Meanwhile, continuing as... Figure 7 and Figure 9As shown, between the first clamping arm 22 and the second clamping arm 23, which are mutually engaged by the first buckle 24a and the first slot 24b, several latches 20a corresponding to the bottle openings 14 of the bottle body are formed. These latches 20a can be secured to the corresponding bottle openings 14. In other words, the latches 20a formed within the bottle opening yoke 20 can secure the bottle openings 14 of all the bottles in the entire bottle assembly 10. In summary, based on connecting several bottles to form the bottle assembly 10 using the male and female buckles 13, this example further utilizes the bottle opening yoke 20 to secure the entire bottle assembly, ensuring the tightness and stability of the bottle assembly. In this example, continuing as... Figure 7 As shown, after the first clamping arm 22 and the second clamping arm 23 are snapped together, they form two latches 20a that correspond to and lock the bottle openings 14 of the first bottle body 11 and the second bottle body, respectively. This further makes the closed bottle opening yoke 20 form as shown in the image. Figure 7 The figure-eight shape shown. In addition, to further ensure the locking effect of the bottle neck lock 20, continue as follows... Figure 8 , Figure 9 and Figure 11 As shown, a shoulder sleeve 40 is also fitted around the bottle neck yoke 20. The shoulder sleeve 40 is tightly fitted around the bottle neck yoke 20 via a second connector 41 to prevent accidental opening of the bottle neck yoke 20. Specifically, the second connector 41 includes a second buckle 41a and a second slot 41b that are interlocked. Similarly, the second buckle 41a can be located on the inner wall of the shoulder sleeve 41, while the second slot 41b is located on the outer wall of the bottle neck yoke 20, that is, on the outer walls of the first clamping arm 22 and the second clamping arm 23 (e.g., ...). Figure 9 As shown), when a first locking block 61 and a second locking block 62 are also provided, the second slot 41b can also be provided simultaneously or separately on the outer side wall of the first locking block 61 and the second locking block 62 (as shown). Figure 11 (As shown); or, the second slot 41b can be located on the inner wall of the shoulder sleeve 41, while the second buckle 41a is located on the outer wall of the bottle neck yoke 20 and / or the first locking block 61 and the second locking block 62. Of course, continuing as... Figure 2 As shown, an outer frame 60 is also provided around the outer wall of the bottle assembly 10. The bottle body is a soft bottle structure that can be squeezed from the side. After the first bottle body 11 and the second bottle body 12 are fastened together, the outer frame 60 surrounds the hard sides of the first bottle body 11 and the second bottle body 12 without covering the soft part. That is to say, the surrounding outer frame 60 not only ensures the stability of the bottle assembly 10 and protects the bottle body from damage, but also reserves the soft part of the bottle body for easy squeezing operation by the user. Furthermore, the soft part is made using a two-color molding process to make it easier for users to distinguish the soft part.

[0059] And continue as Figure 2 , Figure 8 and Figure 9As shown in this example, a discharge nozzle 30 is inserted into the bottle opening 14 of the first bottle body 11 and the second bottle body 12, respectively. The discharge nozzle 30 is connected to the bottle opening 14, and the outer wall of the discharge nozzle 30 is also airtightly connected to the inner wall of the bottle opening 14. An outer cover 50 is also provided above the discharge nozzle 30. The outer cover 50 has two airtight columns 51 corresponding to the number and position of the discharge nozzles 30. Preferably, these are soft rubber airtight columns. By airtightly covering the corresponding discharge nozzles 30 with the airtight columns 51, material leakage can be effectively prevented. The outer cover 50 is fixed to the shoulder sleeve 40 by a third connector. Similarly, the third connector can be a third buckle 42a and a third slot 42b that are interlocked. The third buckle 42a is located on the outer side wall of the shoulder sleeve 40, and the third slot 42b is located on the inner side wall of the outer cover 50; or, the third slot 42b is located on the outer side wall of the shoulder sleeve 40, and the third buckle 42a is located on the inner side wall of the outer cover 50.
