[0002] The dual-compartment bottles in cosmetics mainly address the need for stability in cosmetic formulas and preservation of active ingredients. Each compartment is used to store different materials, which are then mixed before use to improve the stability and preserve the active ingredients of the cosmetics.

[0003] When using cosmetics in a dual-compartment bottle, users often need to mix the different ingredients before pouring out the mixture. Existing dual-compartment bottles typically use a pusher on the pump to allow mixing of the inner and outer compartments. Pressing the pump opens the bottom of the inner compartment, allowing for mixing. This type of dual-compartment bottle requires a specific inner bottle with an openable bottom; it cannot use common one-piece glass bottles, resulting in a complex structure and inconvenient operation. Utility Model Content

[0039] 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 other different 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.

[0040] like Figure 1 As shown, the puncture-type mixing dual-compartment bottle packaging of this utility model includes an outer bottle assembly 1, a bottom cap assembly 2, and a sealed inner bottle 3. The outer bottle assembly 1 has a pointed nozzle on its inner top facing the bottom of the outer bottle. The bottom cap assembly 2 is located at the bottom of the outer bottle assembly 1. The inner bottle 3 is located on the bottom cap assembly 2 inside the outer bottle assembly 1. The inner bottle 3 can be, for example, a glass bottle or a vial, etc., without limitation. The sealing material of the inner bottle 3 is, for example, an aluminum-plastic seal or an aluminum foil seal. It should be noted that the sealing material can be other easily puncturable materials, without limitation. The outer bottle assembly 1 and the inner bottle 3 contain materials. The bottom cap assembly 2 can move the inner bottle 3 within the outer bottle assembly 1 towards the pointed nozzle at the top until the pointed nozzle punctures the seal of the inner bottle 3, thereby achieving mixing of the materials in the outer bottle assembly 1 and the inner bottle 3. It should be noted that the materials can be liquid or solid, without limitation. The puncture-type mixing double-compartment bottle packaging of this utility model can be used to hold cosmetics, etc., and is not limited here.

[0041] like Figure 2 and Figure 3 As shown, the outer bottle assembly 1 of this utility model includes an outer bottle 11, a stopper 12, a top cap 13, and a clamping plate 14. The inner bottle 3 is located inside the outer bottle 11. The outer bottle 11 can be transparent, and the inner bottle 3 can also be transparent, allowing the user to see the materials inside both the outer bottle 11 and the inner bottle 3 from the outside, and also to observe the mixing process of the two materials, making it easy for the user to understand whether the mixing is complete. Of course, the materials and transparency of the inner bottle 3 and the outer bottle 11 are not limited. The upper end of the stopper 12 is airtightly connected and inserted into the mouth of the outer bottle 11, while the lower end of the stopper 12 is located inside the outer bottle 11. The top cap 13 covers the mouth of the outer bottle 11. One side of the clamping plate 14 is pressed tightly against the inside of the top cap 13, and the other side is pressed against the mouth of the outer bottle 11, forming an airtight effect.

[0042] In this example, such as Figure 4As shown, the outer bottle 11 is used to hold materials, which can be solid or liquid. The outer surface of the bottle opening of the outer bottle 11 is threaded, and the inner wall of the top cover 13 is also threaded, thus the top cover 13 is detachably threadedly connected to the bottle opening of the outer bottle 11. Figure 5 and Figure 6 As shown, the upper outer wall of the stopper 12 has an airtight ring 123. The airtight ring 123 can be press-fitted with the inner wall of the bottle mouth of the outer bottle 11. Furthermore, the inner wall of the bottle mouth of the outer bottle 11 is provided with a groove for securing the stopper 12. The airtight ring 123 is secured in the groove, forming an press-fit airtight connection to prevent excessive force from squeezing out the stopper 12 during use and to prevent leakage. Continuing as... Figure 6 As shown, the bottle stopper 12 has a cavity 122 in the middle, through which the mixed material inside the outer bottle 11 can be poured out. The lower end of the bottle stopper 12 has a pointed tip 121 facing the bottom of the bottle, used to puncture the seal of the inner bottle 3. The side wall of the bottle stopper 12 has a wall hole 124 communicating with the cavity 122, through which residual material in the outer bottle can be poured out.

[0043] Continue as Figure 2 and Figure 3 As shown, the bottom cap assembly of this utility model includes a push rod 21, a middle ring 22, and a bottom cap 23. The push rod 21 is located inside the outer bottle 11 of the outer bottle assembly and can move towards the top of the outer bottle 11. The lower section of the push rod 21 passes through the middle ring 22 to the bottom cap 23. The middle ring 22 is located at the bottom of the outer bottle 11, and the middle ring 22 and the bottom of the outer bottle 11 cannot rotate relative to each other. The upper end of the bottom cap 23 is rotatably connected to the middle ring 22, while the lower part of the push rod 21 is axially movable but circumferentially non-rotatable, passing through the bottom cap 23. That is, the bottom cap 23 and the push rod 21 are relatively stationary in the circumferential direction.

[0044] In this example, such as Figure 7 and Figure 8 As shown, the upper section of the push rod 21 is an airtightly connected push seat cavity 211 that passes through the outer bottle 11, and the inner bottle 3 is fixedly held in the push seat cavity 211. The upper part of the inner cavity of the push seat cavity 211 has at least two spaced-apart fixing buckles 2111 that abut against the shoulder of the inner bottle 3, which can fix the inner bottle 3 in the push seat cavity 211 and prevent the inner bottle 3 from shaking. The outer wall of the push seat cavity 211 has a rod airtight ring 2112 that forms an interference fit with the inner wall of the outer bottle 11, ensuring an airtight connection between the push seat cavity 211 of the push rod 21 and the outer bottle 11.

[0045] like Figures 8-10 As shown, the upper part of the middle ring 22 is interlocked with the bottom of the outer bottle 11 of the outer bottle assembly via a circumferential first buckle and a first slot, thus fixing the middle ring 22 to the outer bottle 11 in the axial direction and preventing the middle ring 22 from falling off the bottom of the outer bottle 11. In one example, continuing as... Figure 10As shown, the first slot 221 is located on the upper outer surface of the middle ring 22, and so on. Figure 4 As shown, the first snap fastener 111 is located on the inner surface of the bottom of the outer bottle 11. In another example (not shown), the first snap fastener is located on the upper outer surface of the middle ring 22, and the first slot is located on the inner surface of the bottom of the outer bottle 11. The upper part of the middle ring 22 and the bottom of the outer bottle 11 of the outer bottle assembly are interlocked by axial anti-rotation ribs and anti-rotation slots, that is, the middle ring 22 and the outer bottle 11 are fixed in the circumferential direction to prevent the middle ring 22 from rotating circumferentially relative to the bottom of the outer bottle 11. In one example, continuing as... Figure 10 As shown, the anti-rotation groove 222 is located on the upper part of the middle ring 22, continuing as... Figure 4 As shown, anti-rotation ribs 112 are located at the bottom of the outer bottle 11. Furthermore, two anti-rotation grooves 222 are symmetrically arranged on the upper part of the middle ring 22, and two anti-rotation ribs 112 are symmetrically arranged on the bottom of the outer bottle 11. The two anti-rotation ribs 112 are respectively engaged within the two anti-rotation grooves 222. It should be noted that the number of anti-rotation grooves 222 and anti-rotation ribs 112 is not limited, as long as they can fix the middle ring 22 and the outer bottle 11 relatively in the circumferential direction. In another example (not shown), the anti-rotation ribs are located on the upper part of the middle ring 22, and the anti-rotation grooves are located at the bottom of the outer bottle 11. Continuing as... Figures 8-10 As shown, the inner surface of the middle ring 22 has an internal thread, and the outer surface of the lower rod of the push rod 21 has an external thread. The external thread of the lower rod of the push rod 21 passes through the inner surface of the middle ring 22 and is connected to the internal thread. That is, the lower rod of the push rod 21 and the middle ring 22 can rotate relative to each other. Thus, when the push rod 21 is rotated, the push rod 21 can move up and down under the action of the thread.

[0046] like Figure 11 As shown, the upper part of the bottom cover 23 and the outer surface of the middle ring 22 are connected to each other by a second circumferential latch and a second latch, that is, the bottom cover 23 and the middle ring 22 are fixed in the axial direction, but can rotate relative to each other in the circumferential direction. In one example, continuing as... Figure 11 As shown, the second slot 231 is located on the upper inner surface of the bottom cover 23, continuing as... Figure 9 As shown, the second latch 223 is located on the outer surface of the middle ring 22. In another example, not shown, the second latch is located on the upper inner surface of the bottom cover 23, and the second slot is located on the outer surface of the middle ring 22.

[0047] Continue as Figure 11 As shown, the bottom cover 23 has an internal cavity, and the lower rod of the push rod 21 passes through the internal cavity of the bottom cover 23. Furthermore, the shape of the cavity opening of the bottom cover 23 matches the shape of the lower rod of the push rod 21. A push string 232 is provided at the cavity opening of the bottom cover 23, and so on... Figure 8As shown, the lower rod of push rod 21 has at least one force-bearing surface 212 along its length, and push string 232 abuts against the force-bearing surface 212. Under the constraint of the force-bearing surface 212 and push string 232, the lower rod of push rod 21 and the bottom cover 23 are relatively stationary in the circumferential direction. Therefore, when the bottom cover 23 is rotated, push string 232 abuts against the force-bearing surface 212, causing push rod 21 to rotate together. Then, under the action of the internal thread of the middle ring 22, push rod 21 moves towards the top of the bottle. At this time, push string 232 always abuts against the force-bearing surface 212, and push rod 21 can only move towards the pointed tip of the bottle. In this example, there are two push strings, symmetrically arranged at opposite positions of the cavity opening of the bottom cover 23, and there are also two force-bearing surfaces, also symmetrically arranged on opposite sides of the lower rod of push rod 21. It should be noted that the number is not limited here. Continuing as... Figure 8 As shown, the upper end of the force-bearing surface 212 of the push rod 21 has a raised over-throttle trigger point 2121. Upon initial use, the bottom cover 23 needs to be rotated forcefully to move the over-throttle trigger point 2121 of the push rod 21 past the cavity of the bottom cover, preventing accidental twisting that could cause the push rod 21 to rise and puncture the seal of the inner bottle 3. The lower end of the force-bearing surface 212 of the push rod 21 has a limiting point 2122, such as a latch. This limiting point 2122 cannot pass past the cavity of the bottom cover, thus limiting the rising distance of the push rod 21 and preventing the lower end of the push rod 21 from detaching from the inner cavity of the bottom cover 23.

[0048] like Figure 12As shown, the dual-compartment bottle of this invention is in its initial state before use. At this time, the lower rod of the push rod 21 passes through the inner cavity of the middle ring 22 and the bottom cover 23, and the over-speed trigger point 2121 of the push rod 21 is located inside the cavity of the bottom cover 23. The inner bottle 3 in the upper push seat cavity 211 of the push rod 21 is completely located at the bottom of the outer bottle 11, and the bottle mouth of the inner bottle 3 is a certain distance away from the tip 121 of the stopper 12. When using the dual-compartment bottle, the inner bottle 3 needs to be raised first so that the tip 121 punctures the seal of the inner bottle 3, thereby mixing the material in the inner bottle 3 with the material in the outer bottle 11. Then the user can use the mixed material inside. Specifically, upon initial forceful rotation of the bottom cover 23, the bottom cover 23 drives the push rod 21 to rotate as well. At this time, the push rod 21 moves upward under the action of the thread within the fixed middle ring 22. The over-jump point 2121 on the force-bearing surface 212 of the push rod 21 passes the opening of the inner cavity of the bottom cover 23. Then, gently rotating the bottom cover 23 will move the inner bottle 3 towards the nozzle 121 until the limit point 2122 on the force-bearing surface 212 of the push rod 21 abuts against the opening of the inner cavity of the bottom cover 23, at which point the bottom cover 23 and the push rod 21 can no longer be rotated. At this point, the nozzle 121 just pierces the seal of the inner bottle 3. Gently shaking allows the material in the outer bottle 11 and the material in the inner bottle 3 to flow and mix through the pierced seal of the inner bottle 3 and the wall hole 124 of the stopper 12. Finally, opening the top cover 13 allows the mixture in the dual-compartment bottle to be poured out through the passage 122 of the stopper 12 for use. The structure is simple and the operation is convenient.

[0049] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
