Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a dual-chamber micro-filling easy-to-extract single-use microcapsule for high-concentration, high-viscosity cosmetics. Background Technology

[0002] Single-use cosmetic containers are popular due to their advantages such as simplified ingredients, portability, compact size, and space-saving design. However, existing containers typically use a one-packet format, meaning each container contains a single type of cosmetic with a fixed volume. In practice, users often mix or sequentially use two or more cosmetics, with specific proportions for each. Therefore, with existing containers, users face two problems: first, they need to use multiple containers with different cosmetics; second, because each container has a fixed volume, the proportions may not be the correct ratio for mixing and matching, potentially leading to too much or too little of one cosmetic, thus inconveniencing proper use. Utility Model Content

[0003] The purpose of this invention is to design a dual-chamber micro-filling, easily extruded, single-use microcapsule for high-concentration, high-viscosity cosmetics, to solve the problems mentioned in the background art. To achieve the above objective, the invention includes a main body, the interior of which is divided into a first chamber and a second chamber by a partition structure. The first chamber and the second chamber are arranged laterally side-by-side, and the volume ratio of the first chamber to the second chamber is 1:1 to 1:5. The main body also has an extrusion nozzle, which communicates with at least one of the first chamber and the second chamber. When the extrusion nozzle is connected to one of the first chamber and the second chamber, the partition structure is a breakable connection structure.

[0004] Furthermore, the end of the extrusion nozzle is connected to a tear section via an easy-tear seal, and the tear section has an air cavity inside.

[0005] Furthermore, the separation structure includes an inner heat-sealing line and an outer reinforcing heat-sealing line located on both sides of the inner heat-sealing line.

[0006] Furthermore, a reinforcing rib is provided between the inner heat-sealing line and the outer reinforcing heat-sealing line.

[0007] Furthermore, the extrusion nozzle includes two liquid outlet sections communicating with the tear section through the easy-tear seal, and the first chamber and the second chamber are respectively connected to one of the liquid outlet sections through a conical transition section; Alternatively, the first chamber and the second chamber are respectively connected to one of the liquid outlet sections via a conical transition section, and the tear section is divided into a left tear section and a right tear section by the partition structure. The left tear section and the right tear section are respectively connected to one of the liquid outlet sections via an easy-tear seal.

[0008] Furthermore, the separation structure is a breakable connection structure, which can be separated when subjected to a preset tensile force, and after separation, the first compartment and the second compartment are internally connected.

[0009] Furthermore, the extrusion nozzle includes a liquid outlet section communicating with the tear section through the easy-tear seal, and the first chamber or the second chamber is connected to the liquid outlet section through a conical transition section.

[0010] Furthermore, the inner wall of the conical transition section is provided with spiral guide patterns.

[0011] Furthermore, the taper of the tapered transition section is 5°-15°.

[0012] Furthermore, the main body includes a composite layer, which consists of an anti-adhesion layer, an elastic transition layer, a barrier layer, and a protective layer from the inside out.

[0013] Furthermore, the outer contours of the main body and the torn portion are one of heart-shaped, shield-shaped, square, or conical.

[0014] Furthermore, when the main body is heart-shaped, shield-shaped, or cone-shaped, the main body gradually narrows from wide to narrow along the direction from the end to the tear.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of this utility model is provided with a first chamber and a second chamber. During the production process, according to the statistical user demand, two cosmetics are injected into the single-use container in a specific ratio. Therefore, in actual use, the user only needs to hold the tear part to tear open the easy-tear seal, thereby connecting the internal channel of the extrusion nozzle with the outside. Then, the two cosmetics with a specific ratio can be squeezed out for use. This eliminates the need for users to use multiple single-use containers with different cosmetics in the past. In addition, the actual ratio of the two cosmetics is difficult to control, resulting in one single-use container containing too much or too little cosmetic. Attached Figure Description

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example: In actual use, cosmetics are usually used by mixing two or more cosmetics or using them in sequence, and the amount used is in a certain ratio. Therefore, based on the existing single-use containers, users need to use multiple single-use containers containing different cosmetics. Secondly, since the cosmetics in each single-use container have a fixed capacity, the ratio between these capacities may not be the actual ratio required for use together, which may result in too much or too little of one cosmetic. This makes it inconvenient for users to use the product normally. This utility model uses the combination of two cosmetic products as an example; please refer to... Figs. 1-3This invention provides a dual-chamber micro-filling easy-to-extract single-use microcapsule for high-concentration, high-viscosity cosmetics. It includes a main body 1, whose interior is divided into a first chamber 2 and a second chamber 3 by a partition structure 4. The first chamber 2 and the second chamber 3 are arranged horizontally side-by-side, with a volume ratio of 1:1 to 1:5. During production, two cosmetics are injected into the single-use container in a specific ratio according to user demand. The main body also has an extrusion nozzle 9, which is connected to at least one of the first and second chambers. The end of the nozzle 9 is connected to a tear section 6 via an easy-tear seal 5. The easy-tear seal 5 uses a common easy-tear line; the user simply lifts the tear section 6 to tear open the seal 5, connecting the internal channel of the nozzle 9 to the outside. The two cosmetics in the specific ratio can then be extruded and used. This eliminates the need for multiple single-use containers containing different cosmetics, which previously required controlling the actual ratio of the two cosmetics, leading to situations where one container contained too much or too little cosmetic.

[0021] In this embodiment, the dual-compartment structure described above offers the following advantages over traditional single-use containers: 1. Precise compartmentalization for enhanced efficacy: The dual-compartment design allows for independent packaging of different active ingredients, preventing mutual interference. For example, one compartment focuses on basic repair (such as collagen), while the other targets specific issues (such as acne treatment, whitening, and anti-aging), achieving a synergistic effect of "1+1>2." This modular design meets the needs of different skin types, making it especially suitable for oily, acne-prone, sensitive skin, or users with anti-aging requirements. 2. Freeze-drying for enhanced freshness and higher activity: Ultra-low temperature freeze-drying technology (such as -4°C) is employed. 1. **Cooling at 0℃:** This effectively locks in active ingredients (such as collagen and peptides), reducing the attenuation of active ingredients after opening. The independently sealed dual-compartment design further extends the shelf life, ensuring fresh, highly active skincare ingredients with each use. 2. **Convenient and Efficient, Simple to Use:** The dual-compartment design typically features a press-type dispensing device for precise dosage control, avoiding waste. The product also supports a "twist to activate" function, quickly mixing the ingredients in both compartments, simplifying skincare steps and suitable for busy lifestyles. 3. **Comfortable Feel, Wide Applicability:** Dual-compartment products can adjust texture and formula according to different skin types and needs. For example, the essence compartment has a refreshing texture, while the cream compartment is moisturizing but not greasy, meeting the personalized needs of different skin types such as oily and dry skin. In addition, some products incorporate membrane-penetrating peptide technology to promote ingredient penetration and improve absorption efficiency. 4. **Scientific Skincare, Highly Targeted:** The dual-compartment design reflects a precise understanding of skin problems, such as a "oil-clearing + anti-aging" combination for oily skin, or a "soothing + repairing" solution for sensitive skin. This scientific compartmentalization method provides customized solutions for different skin types, enhancing skincare effectiveness. In summary, the aforementioned dual-compartment design for skincare products, through precise compartmentalization, freeze-drying for freshness preservation, convenient operation, and personalized formulation, offers consumers a more efficient and scientific skincare experience.

[0022] In this embodiment, the tear section 6 has an internal air cavity to facilitate the user's tearing of the easy-tear seal 5; the separation structure 4 includes an inner heat-sealing line and an outer reinforcing heat-sealing line located on both sides of the inner heat-sealing line, thereby improving the tear resistance and preventing liquid leakage during extrusion, thus extending the shelf life of the two cosmetics. Reinforcing ribs are provided between the inner heat-sealing line and the outer reinforcing heat-sealing line, further improving the tear resistance and increasing the tensile strength of the main body 1 in the vertical direction. This ensures that when the user forcibly pulls the tear section 6 away from the main body 1, the breakage occurs first at the easy-tear seal 5, not the main body 1, thus maintaining the integrity of the main body 1 even in cases of abnormal tearing and preventing cosmetic leakage. At this time, the extrusion nozzle 9 includes the easy-tear seal 5 and the tear section 6... Two interconnected liquid outlet sections 7, the first chamber 2 and the second chamber 3 are respectively connected to one liquid outlet section 7 via a conical transition section 8, thereby enabling the extrusion of two cosmetics from the main body 1 in sequence or simultaneously but without mixing; in other embodiments, the first chamber 2 and the second chamber 3 are respectively connected to one liquid outlet section 7 via a conical transition section 8, and the tear section 6 is divided into a left tear section 6 and a right tear section 6 by a partition structure 4. The left tear section 6 and the right tear section 6 are respectively connected to one liquid outlet section 7 via an easy-tear seal 5, thereby ensuring that the two cosmetics do not interfere with each other when extruded sequentially, ensuring that the other cosmetic is not extruded while one cosmetic is being extruded, and both the left tear section 6 and the right tear section 6 are provided with an air chamber; facilitating the tearing operation.

[0023] In other embodiments, the separation structure 4 is a breakable connection structure that can be separated when subjected to a preset tensile force. After separation, the first chamber 2 and the second chamber 3 are internally connected. The extrusion nozzle 9 includes a liquid outlet section 7 that is connected to the tear section 6. The first chamber 2 or the second chamber 3 is connected to the liquid outlet section 7 through a conical transition section 8. When two cosmetics need to be mixed before use, the breakable connection structure can be separated first, and then the two cosmetics can be mixed inside the main body 1. This eliminates the previous process of having to get the cosmetics on one's hands to mix them, ensuring the uniformity of mixing while reducing the contamination of the cosmetics.

[0024] It is worth mentioning that, due to the poor fluidity of highly concentrated and viscous cosmetics (such as thick essences and face creams), they tend to accumulate in the transition section of the main body 1 (the area connecting the chamber to the extrusion nozzle 9). Therefore, in this invention, the inner wall of the conical transition section 8 is provided with spiral guide patterns. The spiral guide patterns can form a "directional channel," guiding the material along the spiral trajectory to concentrate towards the extrusion nozzle 9 during extrusion, avoiding local stagnation. It can also reduce extrusion resistance, i.e., traditional smooth inner walls require greater pressing force to push viscous materials, while the spiral guide patterns can disperse material stress through "diversion + guidance," reducing the friction area between the material and the inner wall, making extrusion easier, especially suitable for female users' operating force. In addition, it can also reduce residue: the spiral structure can conform to the viscous characteristics of the material, and during extrusion, it can drive the residual material attached to the inner wall to move towards the outlet along the spiral trajectory. Combined with the anti-stick coating on the inner wall of the chamber, it can further reduce material residue and improve product utilization. In this embodiment, the taper of the conical transition section 8 is 5°-15°, which can effectively reduce the residue of highly concentrated and viscous materials at the outlet of the main body 1.

[0025] In this embodiment, the main body 1 includes a composite layer, which, from the inside out, consists of an anti-adhesion layer, an elastic transition layer, a barrier layer, and a protective layer. The anti-adhesion layer is made of modified food-grade polyethylene-vinyl acetate copolymer (EVA) film with a thickness of 0.025-0.03 mm, preventing highly viscous materials from sticking together and resisting corrosion from cosmetic ingredients (such as vitamin C and retinol). The elastic transition layer is made of thermoplastic elastomer (TPE) film with a thickness of 0.01-0.015 mm, improving the resilience of the main body 1 after extrusion, facilitating... Residual material flows towards the extrusion end; the barrier layer adopts a double-layer composite structure, with an inner EVOH film (thickness 0.012-0.015mm) and an outer polyamide (PA) film (thickness 0.008-0.01mm), which enhances barrier properties and improves puncture resistance; the protective layer uses a wear-resistant nylon 66 film with a thickness of 0.015-0.02mm and a 0.005-0.008mm thick polytetrafluoroethylene (PTFE) coating on the surface to improve wear resistance and prevent wear during transportation and storage.

[0026] The outer contours of the main body 1 and the tear section 6 are one of heart shape, shield shape, square shape or cone shape. In order to ensure aesthetics, the shapes of the main body 1 and the tear section 6 are chosen to be consistent. When the main body 1 is heart shape, shield shape or cone shape, the main body 1 gradually changes from wide to narrow in the direction from the end to the tear section 6, which makes it easier to squeeze by hand and improves the squeezing efficiency.

[0027] Working principle: Based on the statistical user demand, two cosmetics are injected into the single-use container in a specific ratio during the production process. Therefore, in actual use, the user only needs to hold the tear part 6 to tear open the easy-tear seal 5, thereby connecting the internal channel of the extrusion nozzle 9 with the outside. Then, the two cosmetics in the specific ratio can be squeezed out for use. This eliminates the previous need for users to use multiple single-use containers with different cosmetics; and the difficulty in controlling the actual ratio of the two cosmetics, which led to one single-use container containing too much or too little cosmetic.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
