Description

Technical Field

[0001] This invention relates to the field of dual-compartment container technology, specifically a dual-compartment rotary puncture container. Background Technology

[0002] To improve the stability and efficacy of active ingredients, cosmetic serums often store different components separately. For example, some active ingredients that are easily deactivated, oxidized, or react are not suitable for long-term mixing with the main serum at the time of manufacture. Otherwise, the product may experience problems such as decreased activity, unstable ingredients, and weakened efficacy during storage. Therefore, in the existing technology, dual-compartment containers / packaging are often used to store the two materials separately and then mix them before use.

[0003] While existing dual-compartment cosmetic containers can achieve separate storage to some extent, we have found some shortcomings in practical applications: On the one hand, the opening and mixing methods of existing products are relatively complicated, usually requiring users to perform multiple steps such as pressing, pulling out, disassembling, and puncturing, which is not convenient to use. Especially for cosmetic consumers, if the operation process is too cumbersome, it can easily affect the user experience. On the other hand, existing dual-compartment containers have poor structural linkage during the opening process, which can easily lead to incomplete opening, insufficient material release, and uneven mixing, thus affecting the product's performance. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a dual-compartment rotary puncture container, which has the advantages of convenient operation, reliable opening and sealing, and uniform mixing.

[0005] (II) Technical Solution To achieve the aforementioned objectives of convenient operation, reliable opening, and uniform mixing, this invention provides the following technical solution: a dual-compartment rotating puncture container. It includes a middle layer and an inner layer, the bottoms of which are connected to form a first interlayer between them; The top of the inner cylinder is sealed by a sealing diaphragm, and a first material cylinder for holding the first material is detachably connected to the inner wall of the inner cylinder. A bearing cylinder is rotatably installed inside the first interlayer, and a second material cylinder for holding the second material is installed on the bearing cylinder; The bearing cylinder is provided with a puncturing element that moves up and down along its axial direction to puncture the sealing diaphragm. When the middle layer cylinder and the inner layer cylinder rotate relative to the bearing cylinder and the second material cylinder, they can drive the piercing element to move toward the sealing diaphragm, thereby piercing the sealing diaphragm.

[0006] In this invention, the piercing element is a piercing cylinder that is movably arranged up and down along the axial direction of the bearing cylinder, and the bottom end of the piercing cylinder is provided with a piercing blade for piercing the sealing diaphragm.

[0007] In this invention, the outer wall of the bearing cylinder is provided with a mounting platform, the second material cylinder is mounted on the mounting platform, and the second material cylinder covers the top of the bearing cylinder; The end of the second barrel has a discharge nozzle.

[0008] Furthermore, in this invention, an outer cover is provided outside the middle layer cylinder, and the outer cover is connected to the top of the middle layer cylinder to form a second interlayer between the two. It also includes a bottom shell, the top of which is provided with a snap-fit ​​for fastening into the second interlayer; The bottom shell is used to cover and protect the first material cylinder.

[0009] In this invention, the top of the first material cylinder has a connecting cylinder, which is threadedly connected to the inner wall of the inner cylinder.

[0010] In this invention, further, an annular groove is formed in the outer wall of the bottom of the bearing cylinder, and an annular protrusion is formed on the inner wall of the middle layer cylinder to cooperate with the annular groove. The annular protrusion is rotatably disposed in the annular groove so that the bearing cylinder rotates relative to the middle layer cylinder and restricts the bearing cylinder from detaching axially.

[0011] Furthermore, in this invention, a rotating cylinder is rotatably installed inside the bearing cylinder, and the rotating cylinder is integrated with the inner cylinder; The piercing cylinder is movably disposed inside the rotating cylinder, and a sliding column is fixedly installed on its outer wall; The sliding column cooperates with the guide portion provided on the bearing cylinder and the rotating cylinder to drive the puncture cylinder to move downward along the axial direction when the rotating cylinder and the bearing cylinder rotate relative to each other.

[0012] In this invention, the guide portion further includes a positioning groove and a vertical groove formed on the outer wall of the rotating cylinder. The positioning groove and the vertical groove are connected to form an inverted L-shaped guide groove. The guide section also includes an inclined guide groove formed on the inner wall of the bearing cylinder; The end of the sliding column passes through the inverted L-shaped guide groove and is located in the inclined guide groove.

[0013] Furthermore, in this invention, a locking protrusion is formed on the outer wall of the inner layer cylinder, and the locking protrusion is engaged in a locking groove. The locking groove is formed on the inner wall of the rotating cylinder so that the inner layer cylinder and the rotating cylinder rotate synchronously.

[0014] Furthermore, in this invention, an anti-reverse rotation protrusion is fixedly installed on the outer wall of the bearing cylinder, and a blocking protrusion for preventing the anti-reverse rotation protrusion from rotating in the opposite direction is fixedly installed on the inner wall of the middle layer cylinder.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a dual-compartment rotary puncture container, which has the following beneficial effects: 1. This dual-compartment rotating puncture container, by setting up a first material cylinder and a second material cylinder, allows the first material and the second material to be stored independently, thereby avoiding premature contact between the two essence components during storage and transportation, which helps maintain the stability of the active ingredients and reduces the risk of inactivation, oxidation, and deterioration.

[0016] 2. This dual-compartment rotary puncture container can convert the rotation of the base into the axial downward movement of the puncture component, making operation more convenient and ensuring the stability and reliability of the puncture action, thus avoiding situations where the seal is not fully opened or the puncture is insufficient.

[0017] 3. The dual-compartment rotating puncture container provides good protection for the first material cylinder through the bottom shell, thereby reducing the impact of collisions on the first material cylinder during transportation, carrying, and daily use.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Please see Figures 1-6 This invention discloses a dual-compartment rotating puncture container, mainly used for the compartmentalized storage of cosmetic essences and for immediate mixing during use.

[0023] like Figure 2 and Figure 3 As shown, the container includes a middle cylinder 2 and an inner cylinder 3, with the bottoms of the middle cylinder 2 and the inner cylinder 3 connected to form a first interlayer between them; In this embodiment, the top of the inner cylinder 3 is sealed by a sealing diaphragm 4, and a first material cylinder 5 for holding the first material is detachably connected to the inner wall. Specifically, the top of the first material cylinder 5 has a connecting cylinder 6, which is threaded to the inner wall of the inner cylinder 3. The threaded connection facilitates the assembly, replacement, and installation and fixation of the first material cylinder 5 after filling. To further ensure the sealing, a sealing ring 7 can be provided at the top of the connecting cylinder 6. In this way, the first material is stored in the first material cylinder 5, and due to the sealing diaphragm 4, the first material is in a sealed storage state.

[0024] The sealing diaphragm 4 can be made of aluminum foil, composite sealing film, or other thin film structure that can be pierced by the piercing head 17. Those skilled in the art can make the selection based on the properties of the essence contained, sealing requirements, cost, and other considerations. By setting the sealing diaphragm 4, the two materials can always be kept in an independent sealed state during the product storage, transportation, and sales stages, thereby reducing the risk of active ingredients being deactivated, volatilized, or contaminated.

[0025] like Figure 2 and Figure 3 As shown, an outer cover 1 is provided outside the middle layer cylinder 2. The outer cover 1 is connected to the top of the middle layer cylinder 2, thus forming a second interlayer between the two. After the bottom shell 8 covers and protects the first material cylinder 5, it is snapped into the second interlayer by the snap-fit ​​component on its top, thereby providing better protection for the first material cylinder 5 and helping to reduce the impact of collisions on the first material cylinder 5 during transportation, carrying and daily use. The specific form of the snap-fit ​​component can be selected by those skilled in the art according to actual needs, such as buckles, protrusions and other methods. After the bottom shell 8 is installed, it can form a complete external shell structure together with the outer shell 1 and the middle cylinder 2, so that the first material cylinder 5 inside is covered inside. This not only improves the integrity of the overall appearance, but also improves the user's grip and facilitates the user's rotation operation. When in use, one hand holds the second material cylinder 11 and the other hand rotates the bottom shell 8, so that the user can intuitively complete the opening action. The operation method is simple and easy to understand.

[0026] In this invention, a bearing cylinder 9 is rotatably installed within the first interlayer, and a mounting platform 10 is provided on the outer wall of the bearing cylinder 9. A second material cylinder 11 is detachably installed on the mounting platform 10 via a clamping or other means, and is used to hold the second material. Figure 2 The second material cylinder 11 is covered on top of the bearing cylinder 9 to prevent leakage. In order to facilitate material discharge, in this embodiment, a discharge nozzle 12 is also provided at the end of the second material cylinder 11. The second material cylinder 11 can be pre-filled with the second material before being installed on the mounting platform 10, which facilitates production assembly. After the second material cylinder 11 is placed on top of the carrier cylinder 9, it can not only protect the upper part of the carrier cylinder 9, but also facilitate the mixing of the two materials after the sealing diaphragm 4 is punctured. The setting of the discharge nozzle 12 makes it convenient for users to directly squeeze out and pour out the mixed essence after mixing, which is convenient to use.

[0027] Regarding the rotatable installation of the bearing cylinder 9 within the first interlayer, in this embodiment, as follows: Figure 4 and Figure 5 As shown, an annular groove 13 is recessed on the outer wall of the bottom of the bearing cylinder 9, and an annular protrusion 14 is protruded on the inner wall of the middle cylinder 2 to cooperate with the annular groove 13. The annular protrusion 14 is rotatably disposed in the annular groove 13, so that the bearing cylinder 9 can rotate relative to the middle cylinder 2 and restrict the bearing cylinder 9 from detaching axially.

[0028] like Figure 3 As shown, inside the bearing cylinder 9, a piercing element for piercing the sealing diaphragm 4 is movably arranged up and down along its axial direction. Specifically, when the middle layer cylinder 2 and the inner layer cylinder 3 rotate relative to the bearing cylinder 9 and the second material cylinder 11, they can drive the piercing element to move toward the sealing diaphragm 4, thereby piercing the sealing diaphragm 4, so as to realize the communication and mixing of the first material and the second material. That is, in the initial state, the first material and the second material are stored independently in the first material cylinder 5 and the second material cylinder 11, respectively; when the user performs a rotation operation, the puncturing element is driven to move down and puncture the sealing diaphragm 4, so that the first material that was originally sealed and separated is released and comes into contact with the second material, thereby achieving instant mixing before use.

[0029] Preferably, the puncturing element is a puncturing cylinder 16 that is movably disposed vertically along the axial direction of the bearing cylinder 9, such as... Figure 3The bottom end of the piercing cylinder 16 is provided with a piercing blade 17 for piercing the sealing diaphragm 4. The piercing blade 17 can be set as a pointed cone, multi-blade, or other structure that facilitates piercing, as long as it can effectively pierce the sealing diaphragm 4 when the piercing cylinder 16 moves downward.

[0030] In this embodiment, a rotating cylinder 15 is rotatably installed inside the bearing cylinder 9. The rotating cylinder 15 is integrated with the inner cylinder 3 and can rotate synchronously. Specifically, as shown in the figure... Figure 4 and Figure 5 As shown, a locking protrusion 22 is formed on the outer wall of the inner cylinder 3. The locking protrusion 22 is engaged in the locking groove 23. The locking groove 23 is opened on the inner wall of the rotating cylinder 15. By the locking protrusion 22 being engaged in the locking groove 23, the inner cylinder 3 can rotate synchronously with the rotating cylinder 15. Specifically, the inner cylinder 3 drives the rotating cylinder 15 to rotate. With this configuration, when the user rotates the bottom shell 8, the rotational motion can be transmitted to the rotating cylinder 15 through the outer shell 1, the middle cylinder 2, and the inner cylinder 3. Meanwhile, the bearing cylinder 9 can remain relatively stationary because the second material cylinder 11 is held by the user's other hand, thus creating a relative rotational relationship between the rotating cylinder 15 and the bearing cylinder 9.

[0031] like Figure 6 As shown, the puncture tube 16 is movably arranged inside the rotating tube 15, and a sliding column 18 is fixedly installed on the outer wall of the puncture tube 16. The sliding column 18 cooperates with the guide part provided on the bearing tube 9 and the rotating tube 15, so that when the rotating tube 15 and the bearing tube 9 rotate relative to each other, the puncture tube 16 can be driven to move downward along the axis. Specifically, the guide section includes a positioning groove 19 and a vertical groove 20 on the outer wall of the rotating cylinder 15. The positioning groove 19 and the vertical groove 20 are connected to form an inverted L-shaped guide groove. The guide section also includes an inclined guide groove 21 on the inner wall of the bearing cylinder 9. The end of the sliding column 18 passes through the inverted L-shaped guide groove and is located in the inclined guide groove 21. The positioning groove 19 is used to limit the initial position of the puncture tube 16 so that the puncture tube 16 is stably kept in a high position when it is not opened; the vertical groove 20 is used to provide downward guidance for the sliding column 18; and the oblique guide groove 21 is used to apply axial guidance to the sliding column 18 when it is rotated, thereby forcing the sliding column 18 to gradually move downward.

[0032] like Figure 6As shown, when the sliding column 18 is located in the positioning groove 19 and at the top of the inclined guide groove 21, the piercing cylinder 16 is in a high position. When the bottom shell 8 is rotated, the bottom shell 8 drives the outer cover 1, the middle layer cylinder 2 and the inner layer cylinder 3 to rotate. The rotation of the inner layer cylinder 3 drives the rotating cylinder 15 to rotate. When the rotating cylinder 15 rotates, the sliding column 18 is initially moved from the positioning groove 19 to the vertical groove 20. Then, as the rotating cylinder 15 continues to rotate, the sliding column 18 will gradually move down under the squeezing action of the inclined guide groove 21. The downward movement of the sliding column 18 can drive the piercing cylinder 16 to move down, and then the piercing head 17 can pierce the sealing diaphragm 4. When the sealing diaphragm 4 is punctured, the first material in the first material cylinder 5 can be released through the puncture and communicate with the second material in the second material cylinder 11. At this time, the user can shake or invert the container as needed to mix the two essence components. Then, the mixed essence can be discharged through the outlet 12 for use.

[0033] In order to ensure that the user can always rotate in the correct direction when performing rotation operation, in this embodiment, an anti-reverse rotation protrusion 24 is fixedly installed on the outer wall of the bearing cylinder 9, and a blocking protrusion 25 is fixedly installed on the inner wall of the middle cylinder 2 to prevent the anti-reverse rotation protrusion 24 from rotating in the opposite direction. By blocking the anti-reverse rotation protrusion 24 with the blocking protrusion 25, the rotation direction can be limited.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
