The packaging structure comprises a supporting structure, a first polarizing element and a second polarizing element. The supporting structure is used to accommodate the cosmetic product containing the liquid crystal component. The first polarizing element is arranged on a first side wall of the supporting structure. The second polarizing element is arranged on a second side wall of the supporting structure. The first polarizing element and the second polarizing element are oppositely arranged on two sides of the cosmetic product, and the included angle between the deflection direction of the first polarizing element and the deflection direction of the second polarizing element is greater than 0 degrees.

Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting markings, and in particular to a method for identifying packaging structures and cosmetic products containing liquid crystal components. Background Technology

[0002] With the improvement of living standards, more and more cosmetics are entering our daily lives. Various brands of cosmetics are emerging in endless succession. To improve the skin's absorption and effectiveness of cosmetics, liquid crystal ingredients such as ceramides, phospholipids, surfactants, and cholesterol are added to enhance the stability of the emulsion and strengthen the active ingredients and moisturizing ability of the cosmetics.

[0003] At the same time, with the increase in sales of various brand cosmetics, some cosmetic products that claim to have liquid crystal components may not contain liquid crystal components or only contain a very small amount of them in order to save costs, which brings a bad experience to consumers.

[0004] In traditional sectors, various anti-counterfeiting measures already exist. For example, anti-counterfeiting labels can assign a unique QR code to each cosmetic product, allowing consumers to scan the code with their mobile phones to verify the product's authenticity.

[0005] However, traditional verification methods typically only rely on external packaging information to verify authenticity. They are ineffective against counterfeit products that use genuine packaging but replace the actual product inside. Therefore, how to facilitate consumer verification of the authenticity of cosmetic liquids themselves has become a pressing technical problem. Summary of the Invention

[0006] To solve or at least partially solve the above-mentioned technical problems, the embodiments of this application provide the following technical solutions.

[0007] A packaging structure, characterized in that it comprises: a supporting structural member, a first polarizing element, and a second polarizing element. The supporting structural member is used to hold a cosmetic product containing liquid crystal components. The first polarizing element is disposed on a first side wall of the supporting structural member. The second polarizing element is disposed on a second side wall of the supporting structural member. The first and second polarizing elements are disposed opposite each other on both sides of the cosmetic product, and the angle between the deflection direction of the first polarizing element and the deflection direction of the second polarizing element is greater than 0 degrees.

[0008] Preferably, the supporting structure has a bottom wall and a plurality of side walls vertically connected to the bottom wall, wherein the first side wall and the second side wall are parallel to each other.

[0009] Preferably, a first through hole is formed on the first sidewall, and a first polarizing element is fitted into the first through hole. A second through hole is formed on the second sidewall, and a second polarizing element is fitted into the second through hole.

[0010] Preferably, the support structure further includes a movable ring disposed on at least one of the first through hole or the second through hole. At least one of the first polarizing element or the second polarizing element is embedded in the movable ring, which can rotate freely to adjust the deflection direction of the first polarizing element relative to the second polarizing element.

[0011] Preferably, the outer circumference of the movable ring is provided with teeth, and the supporting structure also includes a gear and a handle. The gear is meshed with the movable ring. The handle is connected to the gear and is used to drive the gear to rotate.

[0012] Preferably, it also includes a deflection direction indicator. The deflection direction indicator is disposed on the movable ring to indicate the deflection direction of the first polarizer and / or the second polarizer.

[0013] Preferably, the supporting structure is a container for holding cosmetic products. Both the first polarizing element and the second polarizing element are attached to the outer surface of the container.

[0014] Preferably, the packaging structure further includes a light source component. The light source component is disposed within the supporting structure, and the light emitted by the light source component passes sequentially through a first polarizer, the cosmetic product, and a second polarizer. The supporting structure also has a first observation hole and a second observation hole, located on both sides of the cosmetic product, and the line connecting the first observation hole and the second observation hole is perpendicular to the path of the light emitted by the light source component.

[0015] Preferably, the deflection directions of the first polarizer and the second polarizer are perpendicular to each other. Both the first polarizer and the second polarizer include: a PVA film, two TAC films, a reflective film, a phase retardation film, and a PSA film. The PVA film polarizes light to limit the vibration of light waves in one direction. The two TAC films are respectively disposed on the upper and lower surfaces of the PVA film to protect it. The reflective film, covering the TAC film, reflects external light as a light source. The phase retardation film compensates for the phase difference during observation to correct the viewing angle. The PSA film is attached to the outer surface of the reflective film to improve its scratch resistance and protect it.

[0016] Embodiments of this application also include a method for identifying cosmetic products containing liquid crystal components, comprising the following steps:

[0017] The first polarizing element and the second polarizing element are respectively placed on both sides of the cosmetic product, and the angle between the deflection direction of the first polarizing element and the deflection direction of the second polarizing element is greater than 0 degrees.

[0018] Observe whether the light passing through the first polarizer, the cosmetic product, and the second polarizer in sequence forms a colored texture; if so, it is determined that the cosmetic product contains liquid crystal components.

[0019] Preferably, the identification method for cosmetic products containing liquid crystal components also includes:

[0020] If no colored texture is observed during the observation process, then:

[0021] Rotate either the first polarizer or the second polarizer;

[0022] Observe whether the light passing through the first polarizer, the cosmetic product, and the second polarizer in sequence produces a colored texture that changes with rotation; if so, it is determined that the cosmetic product contains liquid crystal components; if not, it is determined that the cosmetic product does not contain liquid crystal components.

[0023] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0024] Because light emits vibrations in different directions under normal illumination, the light waves are first filtered out to make them invisible to the naked eye. Then, by utilizing the refraction of light by liquid crystal components, the light waves that were originally obscured are further refracted, creating colored textures. The presence or absence of these colored textures indicates the presence of liquid crystal components, allowing for the detection of whether the liquid in the bottle contains a sufficient amount. This method enables direct identification of the liquid in the container, clearly demonstrating the presence of liquid crystal components in cosmetic products. Attached Figure Description

[0040] As mentioned earlier, some cosmetic products that claim to contain liquid crystal components may not contain liquid crystal components at all, or only contain a very small amount of them, in order to save costs. This leads to a poor experience for consumers.

[0041] In view of this, this patent uses optical methods to allow consumers to intuitively perceive the presence and content of liquid crystal components in the product, thereby improving the user experience.

[0042] First Embodiment

[0043] like Figure 1As shown in the first embodiment of this application, a packaging structure is disclosed, comprising: a supporting structure 1, a first polarizing element 21, and a second polarizing element 22. The supporting structure 1 is used to hold a cosmetic product containing liquid crystal components. The first polarizing element 21 is disposed on a first sidewall 11 of the supporting structure 1. The second polarizing element 22 is disposed on a second sidewall 12 of the supporting structure 1. The first polarizing element 21 and the second polarizing element 22 are disposed opposite to each other on both sides of the cosmetic product, and the angle between the deflection direction of the first polarizing element 21 and the deflection direction of the second polarizing element 22 is greater than 0 degrees.

[0044] The first embodiment of this application also discloses a method for identifying cosmetic products containing liquid crystal components, referencing... Figure 5 As shown, it includes the following steps:

[0045] S1. The first polarizing element 21 and the second polarizing element 22 are respectively disposed on both sides of the cosmetic product, such that the angle between the deflection direction of the first polarizing element 21 and the deflection direction of the second polarizing element 22 is greater than 0 degrees.

[0046] S2. When the material has good transparency, observe whether the light passing through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence forms a colored texture; if so, it is determined that the cosmetic product contains liquid crystal components.

[0047] Common liquid crystal association morphologies include discontinuous cubic liquid crystals, hexagonal liquid crystals, bicontinuous cubic liquid crystals, lamellar liquid crystals, inverse bicontinuous cubic liquid crystals, inverse hexagonal liquid crystals, and inverse discontinuous cubic liquid crystals. Among these, hexagonal liquid crystals, lamellar liquid crystals, and inverse hexagonal liquid crystals can exhibit polarization phenomena under a polarizing plate. Hexagonal liquid crystals are a typical structure of liquid crystals, formed by rod-shaped micelles with both hydrophilic and lipophilic groups within the molecule, creating a hexagonal structure. Generally, amphiphilic molecules with large hydrophilic groups and strong hydrophilicity form hexagonal liquid crystals. Inverse hexagonal liquid crystals are a typical structure of liquid crystals formed by amphiphilic molecules with both hydrophilic and lipophilic groups within the molecule. Rod-shaped micelles with lipophilic groups facing outwards form hexagonal crystals. Strongly hydrophobic amphiphilic compounds with large lipophilic groups form inverse hexagonal liquid crystals. Lamellar liquid crystals are a typical structure of liquid crystals, formed by amphiphilic molecules with both hydrophilic and lipophilic groups within the molecule, exhibiting a layered structure. Amphiphilic molecules have a bilayer membrane in which water is retained in the hydrophilic portion and arranged in a layered manner, while oil may also be present in the lipophilic portion. Because their hydrophilicity and lipophilicity are in balance, they tend to form layered liquid crystals.

[0048] Adding hydrophilic liquid crystals to water-based cosmetics or lipophilic liquid crystals to oil-based cosmetics can significantly improve the quality of the cosmetics.

[0049] The inventors of this application discovered, see [link to relevant documentation] Figure 7As shown, when a light wave passes through a polarizer, the portion that is deflected in the same direction as the polarizer can continue to travel through it. (See also...) Figure 8 and Figure 9 As shown, when the deflection directions of the two polarizers are perpendicular to each other, the transmission of light waves can be completely blocked. However, when a liquid crystal component is placed between the two polarizers, reference... Figure 10 As shown, the deflection direction of light waves passing through the liquid crystal is distorted by the liquid crystal, which allows the light waves to still partially pass through the second polarizer 22, which is perpendicular to the first polarizer 21.

[0050] Besides allowing light waves that shouldn't pass through the second polarizer 22 to pass through, the white light is refracted by the liquid crystal, thus the light waves passing through the second polarizer 22 appear visually as colored spots. A typical effect is as follows: Figure 6 As shown. The appearance of these colored light spots does not necessarily require the first polarizer 21 to be perpendicular to the second polarizer 22. It is easy to understand that colored light spots can still appear even if the first polarizer 21 and the second polarizer 22 are not perpendicular. However, since light waves have different vibration directions, in order to deflect the light waves, the deflection directions of the first polarizer 21 and the second polarizer 22 must be different from each other. Therefore, the angle between the deflection directions of the first polarizer 21 and the second polarizer 22 is greater than 0 degrees.

[0051] However, as a further improvement, the deflection directions of the first polarizer 21 and the second polarizer 22 can be set to be perpendicular to each other. By using two perpendicular polarizers, all normal light waves that are not deflected by the liquid crystal can be blocked. This arrangement makes the final observed refraction effect more pronounced.

[0052] For the structure of the polarizing element, both the first polarizing element 21 and the second polarizing element 22 may include: a PVA film, two layers of TAC film, a reflective film, a phase difference film, and a PSA film. The PVA film polarizes light to limit the vibration of light waves in one direction. The two layers of TAC film are respectively disposed on the upper and lower surfaces of the PVA film to protect it. The reflective film, covering the TAC film, is used to reflect external light as a light source. The phase difference film is used to compensate for the phase difference during observation to correct the viewing angle. The PSA film is attached to the outer surface of the reflective film to improve its scratch resistance and protect it.

[0053] Of course, to protect the first polarizer 21 and the second polarizer 22, a protective film layer can be added to the outermost layer of the first polarizer 21 and the second polarizer 22. Since cosmetic products in containers require transportation, the outer packaging is inevitably subject to bumps and knocks. The protective film layer can protect the first polarizer 21 and the second polarizer 22 from damage by external forces and extend the service life of the first polarizer 21 and the second polarizer 22.

[0054] Second Embodiment

[0055] Referring to the first embodiment, we can see that in order to observe the deflection effect of liquid crystal on light waves in cosmetic products, light waves need to be able to pass through the first polarizer 21 and the second polarizer 22 respectively. Therefore, the first polarizer 21 and the second polarizer 22 must both be located on the irradiation path of the light waves.

[0056] In view of this, such as Figure 1 As shown, the support structure 1 has a bottom wall and multiple side walls vertically connected to the bottom wall, with the first side wall 11 and the second side wall 12 being parallel to each other.

[0057] The first polarizer 21 and the second polarizer 22 are respectively disposed on the first sidewall 11 and the second sidewall 12. Therefore, the positional relationship between the first sidewall 11 and the second sidewall 12 will determine the positional relationship between the first polarizer 21 and the second polarizer 22.

[0058] When the first polarizer 21 and the second polarizer 22 refract light, the light needs to pass through the first polarizer 21 and the second polarizer 22, thus making the light waves invisible. When the first polarizer 21 and the second polarizer 22 are structurally parallel to each other, it is easier to observe through a viewing angle perpendicular to the first polarizer 21 and the second polarizer 22, which is very convenient.

[0059] To facilitate the installation of the first polarizer 21 and the second polarizer 22, refer to Figure 1 A first through hole 111 is provided on the first sidewall 11, and a first polarizing element 21 is fitted into the first through hole 111. A second through hole 121 is provided on the second sidewall 12, and a second polarizing element 22 is fitted into the second through hole 121.

[0060] The first through-hole 111 and the second through-hole 121, located on the first sidewall 11 and the second sidewall 12 respectively, are identical to the interior of the support structure 1, facilitating user observation of the internal structure. The first polarizer 21 and the second polarizer 22 are respectively fitted into the first through-hole 111 and the second through-hole 121. At this point, the first polarizer 21 partially overlaps with the first through-hole 111, and similarly, the second polarizer 22 partially overlaps with the second through-hole 121. Through the first polarizer 21 and the second polarizer 22, the interior of the support structure 1 can be observed, and the presence of liquid crystal components in cosmetic products can be detected and confirmed.

[0061] Third Embodiment

[0062] The first embodiment already provided a packaging structure for observing liquid crystals within cosmetic products through the combination of a first polarizer 21 and a second polarizer 22. Based on the first embodiment, the third embodiment of this application proposes an improved packaging structure that enhances the observation effect.

[0063] refer to Figure 2 The supporting structure 1 also includes a movable ring 112 disposed on at least one of the first through hole 111 or the second through hole 121. At least one of the first polarizing element 21 or the second polarizing element 22 is embedded in the movable ring 112, and the movable ring 112 can rotate freely to adjust the deflection direction of the first polarizing element 21 relative to the second polarizing element 22.

[0064] The third embodiment of this application also discloses a method for identifying cosmetic products containing liquid crystal components. Based on the identification method of the first embodiment and the above-described structure, the identification method of the third embodiment includes:

[0065] S1. The first polarizing element 21 and the second polarizing element 22 are respectively disposed on both sides of the cosmetic product.

[0066] S2. Observe whether the light passing through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence forms a colored texture; if so, determine that the cosmetic product contains liquid crystal components.

[0067] S3. If no colored texture is seen during the observation step, then: rotate either the first polarizer 21 or the second polarizer 22.

[0068] S4. Observe whether the light passing through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence produces a colored texture that changes with rotation; if yes, it is determined that the cosmetic product contains liquid crystal components; if no, it is determined that the cosmetic product does not contain liquid crystal components.

[0069] As mentioned earlier, when light waves pass sequentially through the first polarizer 21, the cosmetic product, and the second polarizer 22, the cosmetic product containing liquid crystals can cause the light waves to be deflected, producing a light wave such as… Figure 6 The colored light spots shown demonstrate the presence of liquid crystal components in the cosmetic product being observed.

[0070] Furthermore, by embedding at least one of the first polarizing element 21 or the second polarizing element 22 into the movable ring 112, the rotation of the movable ring 112 can adjust the deflection direction of the first polarizing element 21 and / or the second polarizing element 22. Moreover, when the angle between the deflection directions of the first polarizing element 21 and the second polarizing element 22 changes, the deflection effect on light also changes. At this time, the liquid crystal in the cosmetic product can refract the deflected light to present different and vibrant color effects. This design can stimulate the user's attention and engagement, thereby further improving the efficiency of anti-counterfeiting authentication.

[0071] It is worth mentioning that, given the presence of the first polarizer 21 and the second polarizer 22, if a colored light spot cannot be observed, the possible reasons include the following two situations:

[0072] In the first scenario, the cosmetic product being observed does not contain liquid crystal components, therefore it cannot re-refract the already refracted light. In this case, no matter how the polarizing element is rotated, a colored light spot cannot be observed.

[0073] In the second scenario, the cosmetic product contains liquid crystal components. However, because the deflection directions of the first polarizer 21 and the second polarizer 22 are completely aligned, the light source passing through the first polarizer 21, after being redirected by the liquid crystal components, cannot pass through the second polarizer 22, thus making it difficult to generate a colored light spot. Under this condition, by rotating one of the polarizers to change the deflection direction, the colored light spot can reappear, thereby achieving the identification effect.

[0074] Fourth embodiment

[0075] The third embodiment discloses a packaging structure with a movable ring 112, which can adjust the relative angle between the first polarizer 21 and the second polarizer 22 by rotating the movable ring 112.

[0076] As a further improvement to the third embodiment, in the fourth embodiment, reference is made to... Figure 3 As shown, the outer periphery of the movable ring 112 is also provided with teeth 1121, and the support structure 1 also includes a gear 113 and a handle 114. The gear 113 is meshed with the movable ring 112. The handle 114 is connected to the gear 113 and is used to drive the gear 113 to rotate.

[0077] When it is necessary to adjust the first polarizer 21 or the second polarizer 22, by rotating... Figure 3 The handle 114 in the middle drives the gear 113 to rotate when the handle 114 is rotated. The rotated gear 113 can drive the movable ring 112 with teeth 1121 arranged around its outer periphery to move. At this time, the first polarizer 21 or the second polarizer 22 can be driven to rotate to adjust the deflection direction corresponding to the polarizer.

[0078] Compared to the third embodiment which only has a single movable ring 112, the rotation of the movable ring 112 driven by the handle 114 and gear 113 is obviously more convenient for the user. It is worth noting that upon receiving the packaging structure and seeing the externally mounted handle 114, the user can immediately associate it with rotation. This design guides the user to observe the liquid crystal components in the cosmetic product by rotating the first polarizing element 21 or the second polarizing element 22.

[0079] It is worth mentioning that, despite Figure 3 , Figure 4 In this configuration, gear 113 and movable ring 112 are exposed outside the supporting structure 1. However, these structures could also be housed within the interlayer of the packaging structure.

[0080] In addition, the support structure 1 may also include a deflection direction indicator. The deflection direction indicator is disposed on the movable ring 112 to indicate the deflection direction of the first polarizer 21 and / or the second polarizer 22.

[0081] The deflection direction indicator can indicate the deflection direction of the polarizer, making it easier for the user to grasp the current deflection direction of the first polarizer 21 or the second polarizer 22, making the operation more convenient and increasing the fun of operation.

[0082] Fifth embodiment

[0083] In the previous embodiments, it was necessary to use external light to observe cosmetic products. However, it is difficult to observe cosmetic products in environments with poor lighting.

[0084] In view of this, refer to Figure 11 and Figure 12 As shown, the packaging structure also includes a light source component 3. The light source component 3 is disposed within the support structure 1, and the light emitted by the light source component 3 passes sequentially through the first polarizer 21, the cosmetic product, and the second polarizer 22. The support structure also has a first observation hole 13 and a second observation hole 14, which are located on both sides of the cosmetic product.

[0085] Optionally, the line connecting the first observation hole 13 and the second observation hole 14 is perpendicular to the path of the light emitted by the light source component 3.

[0086] When it is necessary to observe the cosmetic product, the light source component 3 located inside the packaging structure is turned on, so that the light source component 3 can provide sufficient light for observing the cosmetic product. When the cosmetic product contains liquid crystal components, the observer can observe the colored light spots presented by the light passing through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence through the observation hole located on the support structure.

[0087] When the packaging structure is placed under natural light without the light source component 3, the natural light passes sequentially through the first polarizer 21, the cosmetic product, and the second polarizer 22, generating a light spot when the cosmetic product contains liquid crystal components. However, if the weather is bad and the light is weak, observing the cosmetic product becomes difficult. The light source component 3 can be switched on and off as needed to provide light, making the lighting more controllable and adaptable to more usage scenarios compared to relying solely on natural light.

[0088] Neither the first observation aperture 13 nor the second observation aperture 14 is located on the path of the light emitted by the light source component 3, and neither the first polarizer 21 nor the second polarizer 22 is located on the line connecting the first observation aperture 13 and the second observation aperture 14. Therefore, when observing cosmetic products through the first observation aperture 13 and the second observation aperture 14, the original color of the cosmetic product under natural light can be observed. This arrangement facilitates comparison of the refracted colored stripes by the user, making the identification results more rigorous.

[0089] Sixth Embodiment

[0090] In the aforementioned embodiments, the packaging structure mentioned is exemplarily represented as an outer packaging box. A transparent container containing cosmetic products is placed inside the outer packaging box, thereby enabling the identification of the cosmetic products within the container.

[0091] Unlike the examples in the preceding embodiments, in the sixth embodiment of this application, the support structure 1 can also be a container for holding cosmetic products. The first polarizer 21 and the second polarizer 22 are both attached to the outer surface of the container.

[0092] By attaching the first polarizer 21 and the second polarizer 22 to the outer surfaces of both sides of the container, the container can be lifted up to directly observe whether the light passing through the container forms a colored spot, thus completing the identification of whether the cosmetic product contains liquid crystal.

[0093] This design simplifies the packaging structure and reduces costs compared to placing it on the outer packaging box.

[0094] In addition, two symmetrical slots can be provided on the outer surface of the container to bend the first polarizing element 21 and the second polarizing element 22 and insert them into the slots for testing the cosmetic products inside the container. After testing, the first polarizing element 21 and the second polarizing element 22 can be retained for testing other cosmetic products, thus reducing the consumption of the first polarizing element 21 and the second polarizing element 22.

[0095] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above descriptions are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
