Description

Technical Field

[0001] This application relates to the field of packaging technology, specifically to the field of biphase mixing bottle technology. Background Technology

[0002] In multiple sectors, including cosmetics, beverages, and chemical products, there is a need to package active ingredients separately from the base liquid to ensure product stability and efficacy.

[0003] For example, in the cosmetics market, especially for high-efficiency skincare products, there are usually two parts: a base liquid and active ingredients. The base liquid often contains ingredients that adjust the skin feel, moisturize, and provide other auxiliary functions, such as glycerin, sodium hyaluronate, and butylene glycol. The active ingredients, on the other hand, may exist in the form of liquid serums or powders, such as vitamin C, peptides, and yeast extracts, which are substances with highly effective antioxidant and anti-aging functions.

[0004] Active ingredients are prone to oxidation or degradation when stored in aqueous solutions for extended periods, thus reducing their effectiveness. Some active ingredients may be in solid powder form; direct mixing with liquids may result in insufficient solubility or precipitation, affecting the product's efficacy. Once two ingredients are mixed, the product's shelf life will be significantly shortened due to the aforementioned chemical reactions or physical changes.

[0005] In response, patent CN201921441966.3 discloses a two-liquid mixing titration bottle with a puncture device fixedly connected to the mixing bottle, allowing mixing by puncturing the seal. However, this solution has the potential problem of insufficient mixing due to unsatisfactory flow after puncture, as well as inconvenience in use.

[0006] Meanwhile, after mixing, the bottle remains intact due to the presence of puncture-resistant parts, making it inconvenient to use. To address this, patent CN202410135126.3 discloses a container bottle with a mixing dispensing mechanism that allows the pressing plate to apply pressure to the dispensing pump at different levels by rotating the adjusting seat, thereby extracting substances in different proportions for mixing. However, this immediate extraction and mixing method may result in insufficient mixing if applied to the cosmetics industry. Summary of the Invention

[0007] In response to the aforementioned needs, this application proposes a biphasic mixing bottle, which aims to achieve safe storage of two different cosmetic ingredients in the same bottle through a novel packaging design, and to allow users to easily mix and use the ingredients instantly.

[0008] To achieve the above objectives, the present application adopts the following technical solution:

[0009] A biphase mixing bottle includes a bottle body for filling a first component, a bottle cap, and an essence chamber that can be fitted onto the top surface of the bottle opening and partially enters the interior of the bottle body. The essence chamber is filled with a second component, and the bottom of the essence chamber is provided with a release port for releasing the second component into the bottle body.

[0010] It also includes a connecting rod that seals the release port at its lower end when the first component and the second component are separated, is interference-fitted with the bottle cap, and applies pressure to seal the release port as the bottle cap is tightened. The connecting rod moves as the bottle cap is turned open and releases the seal of the release port.

[0011] It also includes a replaceable sealing cap when the first and second components are mixed.

[0012] In this way, by storing the first and second ingredients separately in the bottle and the essence compartment, the chemical reactions or physical incompatibility problems (such as oxidation, precipitation, etc.) that may be caused by mixing the two ingredients in advance are avoided, thereby ensuring the optimal stability and effectiveness of each ingredient.

[0013] Users simply twist open the cap to trigger the connecting rod, releasing the seal on the release port and allowing the second ingredient to flow smoothly into the bottle and mix with the other ingredients. This design is not only easy to operate but also requires no additional tools or complicated steps, greatly enhancing the user experience. Furthermore, after mixing, the original cap can be replaced with a sealing cap for convenient storage and use.

[0014] In some possible implementations, the sealing cap is a solution extraction cap and / or a bottle cap.

[0015] In some possible implementations, the solution extraction cap is a dropper head and / or a pump head.

[0016] In some possible implementations, the dropper head is provided with a suction tip that passes through the discharge port.

[0017] In some possible implementations, the pump head is provided with a suction tube that passes through the release port.

[0018] In some possible implementations, the essence container has a protective film on its top before the second ingredient is filled.

[0019] In some possible implementations, the lower end of the essence chamber is provided with a base cavity that is separated from its inner cavity, and the lower end of the connecting rod is completely housed in the base cavity after being inserted into the release port.

[0033] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0034] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0035] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0036] Please refer to Figure 1 This application discloses a twist-open dual-chamber essence device for scenarios where a portion of the base liquid and active ingredients are stored separately in one container, and then mixed during use. The active ingredients can be liquid or powder, and the ratio of base liquid to active ingredients generally varies greatly depending on the application, such as 2:1 or 5:1. Therefore, ensuring compatibility during mixing is crucial. Simultaneously, the universality of the container must be considered. In the cosmetics industry, for example, there are numerous product categories and standard cap sizes, such as 24cm and 28cm, necessitating consideration of compatibility with existing caps.

[0037] Please refer to the reference. Figures 1 to 3 This application discloses a twist-open dual-chamber essence device, comprising an essence chamber 1 that can be fitted onto the top surface of the bottle opening 110 and partially enter the interior of the bottle body 100, and a connecting rod 2 that moves with the twisting of the bottle cap 200. Please refer to [reference needed] for details. Figure 2 In the diagram, the essence chamber 1 is fitted onto the top surface of the bottle opening 110 from top to bottom and enters at least the bottle opening 110. At the same time, the essence chamber 1 will partially enter the interior of the bottle body 100, where the bottle body 100 refers to the cavity including the bottle opening 110. In other words, the active ingredients in the essence chamber 1 are mostly contained within the bottle opening 110. If the bottle opening 110 is long enough, as mentioned above, the essence chamber 1 can remain only inside the bottle opening 110.

[0038] The following explains the sealing method when the essence compartment 1 is installed at the bottle opening 110. Please refer to... Figure 2 and Figure 3 The essence chamber 1 includes a chamber body 11 and a sealing skirt 12 formed by two-color injection molding at the upper end of the chamber body 11. The chamber body 11 is made of PP (polypropylene) material, and the sealing skirt 12 is made of TPU (thermoplastic polyurethane elastomer) material, which can achieve a good seal without the need for a gasket.

[0039] As another embodiment of the sealing method, please refer to Figures 4 to 6 The essence chamber 1 of this application is integrally molded and made of PP material. It has an outer edge 13 at its upper end, and a first sealing gasket 3 is provided between the outer edge 13 and the bottle mouth 110. At this time, under the condition of facilitating the processing of the essence chamber 1, it can be sealed with the help of the gasket.

[0040] Furthermore, please refer to the references. Figures 7 to 8The essence chamber 1 has a release port 12 at the bottom of its inner cavity. It is a through-hole design that allows the active ingredients inside the inner cavity to be released into the bottle body 100. The lower end of the connecting rod 2 has an insert 21 that can be fitted into the release port 12. At the same time, the upper end of the insert 21 has a sealing ring 22 that seals the release port 12 from top to bottom through the inner cavity of the essence chamber 1. Figure 7 This is a schematic diagram of the twist-open dual-chamber essence device of this application in the state without the cover 200 assembled. At this time, the essence chamber 1 and the connecting rod 2 are combined. During the product packaging process, a protective film (not shown in the figure) is covered on the upper end of the essence chamber 1 to prevent foreign objects from falling in during handling and placement.

[0041] Please continue to refer to this. Figure 8 In some embodiments, the lower end of the essence chamber 1 is provided with a base cavity 13 that is separated from its inner cavity. The insert portion 21 at the lower end of the sealing ring 22 is fully housed in the base cavity 13 after being fitted into the release port 12. At this time, the lower end of the connecting rod 2 is completely located within the base cavity 13 and does not exceed the opening plane of the base cavity 13, so as to ensure the stability of the essence chamber 1 on the placement surface.

[0042] Further, please refer to Figure 1 A first interference fit 10 is provided between the upper end of the connecting rod 2 and the bottle cap 200, and a second interference fit 20 is provided between the lower end of the connecting rod 2 and the essence chamber 100. The interference amount of the second interference fit 20 is less than that of the first interference fit 10, allowing the connecting rod 2 to release the seal on the release port 12 as the bottle cap 200 moves upward relative to the essence chamber 1 during the process of unscrewing the bottle cap 200.

[0043] In this way, the base liquid and active ingredients are effectively stored in separate spaces (i.e., the bottle body 100 and the essence compartment 1). In use, the user simply twists open the cap 200, triggering the connecting rod 2 to move upwards relative to the essence compartment 1, automatically releasing the seal on the release port 12. Instant mixing of the ingredients is achieved without additional tools or complicated steps. This design is not only easy to operate but also ensures that different ingredients are thoroughly mixed.

[0044] The interference fit is explained in detail below. Please refer to the following. Figure 8 and Figure 9The essence chamber 1 extends from the release port 12 into the base cavity 13 via a guide sleeve 14, which is the inner ring of the release port 12 of the essence chamber 1 extending downwards. The insert 21 fits into the guide sleeve 14, forming a second interference fit 20, which stably fixes the connecting rod 2 in the essence chamber 1 and maintains its axial vertical position. Specifically, the inner ring of the guide sleeve 14 may have a groove 141, and the corresponding insert 21 may have a flange 211. Both the groove 141 and the flange 211 may be annular, thus making it easier to disengage when the bottle cap 200 is opened through a smooth interference fit.

[0045] Furthermore, when the bottle cap 200 is screwed in, the sealing ring 22 applies pressure to the outer edge of the release port 12. At this time, stress concentration occurs in the interference-fit guide sleeve 14 and the insert 21, which may lead to deformation. To address this, this application provides at least one axial stress relief hole 212 in the portion of the insert 21 within the base cavity 13. Preferably, there is one stress relief hole 212, which is formed by axially hollowing out the insert 21 of the connecting rod 2. During the compression process of tightening the bottle cap 200, the normal operation and sealing performance of the connecting rod 2 can be ensured.

[0046] Please refer to Figure 1 and Figure 10 A hollow sleeve 210 extending from the inside of the cap 200 into the inner cavity of the bottle body 100 is nested with the upper end of the connecting rod 2, forming a first interference fit portion 10. Specifically, a concave tolerance section 23 is provided at the upper end of the connecting rod 2, where the depth of the hollow sleeve 210 is greater than the length of the tolerance section 23. Thus, when the cap 200 is tightened, the tolerance section 23 can be nested into the hollow sleeve 210, and as the tightening process progresses, the interference fit between the cap 200 and the connecting rod 2 becomes increasingly tight. Simultaneously, because the depth of the hollow sleeve 210 is sufficient, the interference fit at the essence chamber 1 and the connecting rod 2 is not affected. Therefore, it can also be ensured that when the cap 200 is unscrewed, it can move the connecting rod 2 along with it, releasing the release port 12 and completing the mixing of active ingredients. Moreover, this creates a top-down through-hole mixing method, which has a better mixing effect than the method of piercing the protective film described in the background art.

[0047] Please refer to Figure 9 Considering that insufficient force may affect the sealing of the connecting rod 2 and the essence chamber 1 during the tightening process of the bottle cap 200, in some embodiments, a second sealing gasket 4 is provided between the sealing ring 22 and the bottom surface of the inner cavity of the essence chamber 1.

[0048] Please continue to refer to this. Figure 9When the connecting rod 2 moves, there is a risk that the moving components at the upper end of the sealing ring 22 may be carried out simultaneously. To address this, in some embodiments of this application, an oleophobic coating 221 is provided at the upper end of the sealing ring 22. Oleophobic coatings are a common technique in the industry, such as fluorocarbon coatings and siloxane coatings, which will not be described in detail here.

[0049] The following describes the two-phase mixing bottle used in the twist-open dual-chamber essence device described above. Since the active ingredients of the essence, in addition to the base solution, can be either liquid or powder, the mixing bottle used in this device will be described as a two-phase mixing bottle.

[0050] Please refer to Figure 11 This describes the process of filling a two-way mixing bottle using a twist-open dual-chamber essence device. In Figure (a), the base solution is filled into the empty bottle body 100. Then, as shown in Figure (b), the essence chamber 1 is installed and the active ingredients are filled. If there is a protective film on the top of the essence chamber 1, it can be removed at this stage. After filling the essence chamber 1, the bottle cap 200 is tightened as shown in Figure (c). The bottle cap 200 is a threaded cap. A first sealing gasket 3 can be added at this stage. If there is a sealing skirt 12, no additional gasket is needed.

[0051] It should be further noted that in practical applications, the proportion of the base solution is usually greater than that of the active ingredient. Therefore, the bottle contains 100ml of base solution. However, if other formulations result in a higher proportion of active ingredient than base solution, the filling positions of the base solution and active ingredient can be interchanged. This application does not impose specific limitations on this comparison. To illustrate that the filling can be interchanged, the component in the bottle containing 100ml is referred to as the first component, and the component in the essence container 1 is referred to as the second component.

[0052] Please continue to refer to this. Figure 12 When in use, as shown in Figure (a) of the product packaging status, and in Figure (b) of the product packaging status, unscrewing the cap 200, at which point the connecting rod 2 is removed. At this time, the active ingredients in the essence chamber 1 flow down and mix with the base solution in the bottle body 100. Afterwards, you can either tighten the cap 200 again for use, or remove the connecting rod 2, or even remove the essence chamber 1 and continue using it as a regular bottle.

[0053] The fixing cap can be replaced later. The fixing cap can be the bottle cap 200 that is removed from the connecting rod 2, or it can be the solution extraction cap. Please refer to the following embodiment.

[0054] Furthermore, removing the essence container 1 will simultaneously spill residual active ingredients and the mixed solution, posing a cumbersome and potentially problematic task. To address this, a solution extraction cap can be used to replace the cap 200 after unscrewing it, facilitating easier use. As shown in Figure (c), a dropper head 300 can be used; as shown in Figure (d), it can have a threaded cap screwed into the bottle body 100. In this case, the suction tip 310 can pass through the release port 12, allowing the suction tip 310 to remain stably centered during use.

[0055] Please refer to Figure 13 As shown in Figures (a) and (b), the bottle cap 200 can be unscrewed. Please refer to Figure (c) for the pump head 400, which, as shown in Figure (d), has a threaded cap that can be screwed into the bottle body 100. At this time, the straw 410 can pass through the release port 12, and the straw 410 can be kept in a stable central position during use.

[0056] As stated above, this case protects a two-phase mixing bottle, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
