Description

Technical Field

[0001] The present application relates to the field of anti-counterfeiting marks, and in particular to a packaging structure and an identification method for cosmetic products containing liquid crystal components. Background Art

[0002] At present, with the improvement of the quality of life, more and more cosmetics are entering our daily lives. Various brands of cosmetics are emerging one after another. In order to make the cosmetics work better on the skin and enhance the effect when used, liquid crystal ingredients such as ceramide, phospholipids, surfactants and cholesterol are added to the cosmetics to enhance the emulsion stability of the cosmetics and enhance the active ingredients and moisturizing ability of the cosmetics.

[0003] At the same time, with the growth in sales of various brands of cosmetics, some cosmetic products claiming to contain liquid crystal ingredients may not add liquid crystal ingredients to the cosmetics in order to save costs, or only add very small amounts of ingredients, which brings a bad experience to consumers who use them.

[0004] In the traditional field, there are already various anti-counterfeiting methods, such as anti-counterfeiting labels, on which a unique QR code can be assigned to each cosmetic product, and consumers can verify the authenticity of the cosmetic product by scanning the QR code with their mobile phones.

[0005] However, traditional verification methods can usually only verify the authenticity of the product through the external packaging information, and cannot achieve the purpose of anti-counterfeiting for counterfeit products that use genuine packaging but replace the internal products. Therefore, how to facilitate consumers to prevent and verify the cosmetic liquid itself has become a technical problem to be solved. Summary of the invention

[0006] In order to solve or at least partially solve the above technical problems, the embodiments of the present application provide the following technical solutions.

[0007] A packaging structure, characterized in that the packaging structure comprises: a supporting structure, a first polarizer and a second polarizer. The supporting structure is used to place a cosmetic product containing a liquid crystal component. The first polarizer is arranged on a first side wall of the supporting structure. The second polarizer is arranged on a second side wall of the supporting structure. The first polarizer and the second polarizer are arranged on two sides of the cosmetic product relative to each other, and the angle between the deflection direction of the first polarizer and the deflection direction of the second polarizer 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, and 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 side wall, and the first polarizer is embedded in the first through hole. A second through hole is formed on the second side wall, and the second polarizer is embedded in the second through hole.

[0010] Preferably, the supporting structure also 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 polarizer or the second polarizer is embedded in the movable ring, and the movable ring can rotate freely to adjust the deflection direction of the first polarizer relative to the second polarizer.

[0011] Preferably, teeth are arranged on the outer circumference of the movable ring, 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 to drive the gear to rotate.

[0012] Preferably, the device further comprises: a deflection direction indicator, which is arranged 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 containing cosmetic products. The first polarizer and the second polarizer are both attached to the outer surface of the container.

[0014] Preferably, the packaging structure further includes: a light source component. The light source component is arranged in the supporting structure component, and the light irradiated by the light source component passes through the first polarizer, the cosmetic product and the second polarizer in sequence. The supporting structure is also provided with a first observation hole and a second observation hole, the first observation hole and the second observation hole are 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 light path emitted by the light source component.

[0015] Preferably, the deflection directions of the first polarizer and the second polarizer are perpendicular to each other. The first polarizer and the second polarizer both include: a PVA film, two layers of TAC film, a reflective film, a phase difference film and a PSA film. The PVA film can polarize light to limit the vibration of light waves in one direction. The two layers of TAC film are respectively arranged on the upper and lower surfaces of the PVA film to protect the PVA film. The reflective film is covered on the TAC film and 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 during observation. The PSA film is attached to the outer surface of the reflective film to improve the scratch resistance of the reflective film and protect the reflective film.

[0016] The embodiment of the present application also includes a method for identifying a cosmetic product containing a liquid crystal component, comprising the following steps:

[0017] The first polarizer and the second polarizer are respectively arranged on two sides of the cosmetic product, so that the angle between the deflection direction of the first polarizer and the deflection direction of the second polarizer is greater than 0 degree;

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

[0019] Preferably, the method for identifying a cosmetic product containing liquid crystal components further comprises:

[0020] During the observation step, if no colored texture is seen, then:

[0021] rotating either one of the first polarizer and the second polarizer;

[0022] Observe whether the light successively passing through the first polarizer, the cosmetic product and the second polarizer produces a color 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 embodiments of the present application have the following beneficial effects:

[0024] Since light will have vibration waves in different directions under normal irradiation, first of all, all the light waves in the light are filtered so that the light cannot be observed by the naked eye. Secondly, by using the liquid crystal component to deflect the light, the light waves that were originally deflected and could not be observed are deflected again, thereby generating color textures. The liquid crystal component can be judged by whether there is a color texture, and it can be detected whether the liquid in the bottle contains a sufficient amount of liquid crystal components. In this way, the liquid in the container can be directly identified, and it can be intuitively clear that the cosmetic product contains liquid crystal components. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] As mentioned above, some cosmetic products claiming to contain liquid crystal ingredients may not add liquid crystal ingredients to the cosmetics in order to save costs, or only add very small amounts of ingredients, which brings a bad experience to consumers who use them.

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

[0042] First embodiment

[0043] like Figure 1As shown, a packaging structure is disclosed in the first embodiment of the present application, and the packaging structure includes: a supporting structure 1, a first polarizer 21 and a second polarizer 22. The supporting structure 1 is used to place a cosmetic product containing liquid crystal components. The first polarizer 21 is arranged on the first side wall 11 of the supporting structure 1. The second polarizer 22 is arranged on the second side wall 12 of the supporting structure 1. The first polarizer 21 and the second polarizer 22 are arranged on both sides of the cosmetic product, and the angle between the deflection direction of the first polarizer 21 and the deflection direction of the second polarizer 22 is greater than 0 degrees.

[0044] The first embodiment of the present application also discloses a method for identifying a cosmetic product containing a liquid crystal component, referring to Figure 5 As shown, the following steps are included:

[0045] S1. Arrange the first polarizer 21 and the second polarizer 22 on two sides of the cosmetic product respectively, so that the angle between the deflection direction of the first polarizer 21 and the deflection direction of the second polarizer 22 is greater than 0 degree.

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

[0047] Common liquid crystal association forms include non-continuous cubic liquid crystal, hexagonal liquid crystal, bicontinuous cubic liquid crystal, lamellar liquid crystal, inverse bicontinuous cubic liquid crystal, inverse hexagonal liquid crystal, and inverse non-continuous cubic liquid crystal. Among them, hexagonal liquid crystal, lamellar liquid crystal and inverse hexagonal liquid crystal can be observed to be polarized under a polarizing plate. Hexagonal liquid crystal is one of the typical structures of liquid crystal. It is a hexagonal structure formed by rod-shaped micelles with hydrophilic and lipophilic groups in the molecule. Generally, amphiphilic molecules with large hydrophilic groups and strong hydrophilicity form hexagonal liquid crystals. Inverse hexagonal liquid crystal is one of the typical structures of liquid crystal formed by amphiphilic molecules with hydrophilic and lipophilic groups in the molecule. Rod-shaped micelles with lipophilic groups facing outward form hexagonal crystals. Strongly hydrophobic amphiphilic compounds with large lipophilic groups form inverse hexagonal liquid crystals. Lamellar liquid crystal is one of the typical structures of liquid crystal. It is formed by amphiphilic molecules with hydrophilic and lipophilic groups in the molecule. It is a liquid crystal with a lamellar structure. The bilayer film of amphiphilic molecules holds water in the hydrophilic part and arranges in a lamellar manner, and oil may also exist in the lipophilic part. Because its hydrophilicity and lipophilicity are balanced, it tends to form lamellar liquid crystals.

[0048] Adding hydrophilic liquid crystals to water-based cosmetics, or adding lipophilic liquid crystals to oily cosmetics, can greatly improve the quality of the cosmetics.

[0049] The inventor of the present application discovered that Figure 7As shown in , when a light wave passes through a polarizer, the part with the same deflection direction as the polarizer can continue to pass through the polarizer. Figure 8 and Fig. 9 As shown in FIG. 1 , 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 product with a liquid crystal component is set between the two polarizers, Fig.10 As shown, the deflection direction of the light wave passing through the liquid crystal will be distorted by the liquid crystal, so that the light wave can still partially pass through the second polarizer 22 which is perpendicular to the first polarizer 21 .

[0050] In addition to allowing light waves that should not pass through the second polarizer 22 to pass through, the white light is deflected due to passing through the liquid crystal, so the light waves passing through the second polarizer 22 can produce colorful light spots visually. Typical effects are as follows: Figure 6 As shown. The appearance of these colored light spots does not necessarily require that the first polarizer 21 must be perpendicular to the second polarizer 22. It is easy to understand that even if the first polarizer 21 and the second polarizer 22 are not perpendicular, colored light spots can still appear. However, since light waves have different vibration directions, in order to be able 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 direction of the first polarizer 21 and the deflection direction of 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. The two perpendicular polarizers can completely block the normal light waves that are not deflected by the liquid crystal. Such a setting can make the refraction effect observed in the end more obvious.

[0052] As for the structure of the polarizer, the first polarizer 21 and the second polarizer 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 can polarize light to limit the vibration of light waves in one direction. Two layers of TAC film are respectively arranged on the upper and lower surfaces of the PVA film to protect the PVA film. The reflective film is covered on the TAC film 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 during observation. The PSA film is attached to the outer surface of the reflective film to improve the scratch resistance of the reflective film and protect the reflective film.

[0053] Of course, in order 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 the cosmetic products in the container need to be transported, the outer packaging is inevitably bumped. The protective film layer can protect the first polarizer 21 and the second polarizer 22 from damage by external forces, thereby extending 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 the liquid crystal on the light wave in the cosmetic product, the light wave needs to be able to pass through the first polarizer 21 and the second polarizer 22 respectively, so the first polarizer 21 and the second polarizer 22 must be located on the irradiation path of the light wave.

[0056] In view of this, if Figure 1 As shown, the supporting structure 1 has a bottom wall and a plurality of side walls vertically connected to the bottom wall, and the first side wall 11 and the second side wall 12 are parallel to each other.

[0057] The first polarizer 21 and the second polarizer 22 are disposed on the first side wall 11 and the second side wall 12 respectively. Therefore, the positional relationship between the first side wall 11 and the second side wall 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 deflect the light, the light needs to pass through the first polarizer 21 and the second polarizer 22, so that the light waves in the light are deflected and become invisible. When the first polarizer 21 and the second polarizer 22 are parallel to each other in structure, 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] In order to facilitate the installation of the first polarizer 21 and the second polarizer 22, refer to Figure 1 The first side wall 11 is provided with a first through hole 111 , and the first polarizer 21 is engaged with the first through hole 111 . The second side wall 12 is provided with a second through hole 121 , and the second polarizer 22 is engaged with the second through hole 121 .

[0060] The first through hole 111 and the second through hole 121 provided on the first side wall 11 and the second side wall 12 are the same as the inside of the supporting structure 1, which can facilitate the user to observe the internal situation. The first polarizer 21 and the second polarizer 22 are respectively embedded in the first through hole 111 and the second through hole 121. At this time, the first polarizer 21 will overlap with the first through hole 111. Similarly, the second polarizer 22 will overlap with the second through hole 121. Through the first polarizer 21 and the second polarizer 22, the inside of the supporting structure 1 can be observed, and whether the inside of the cosmetic product contains liquid crystal components can be detected and confirmed.

[0061] Third embodiment

[0062] In the first embodiment, a packaging structure is provided, and liquid crystal in the cosmetic product is observed by combining the first polarizer 21 and the second polarizer 22. Based on the first embodiment, the third embodiment of the present application provides an improved packaging structure, which can improve the observation effect.

[0063] refer to Figure 2 The supporting structure 1 further 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 polarizer 21 or the second polarizer 22 is embedded in the movable ring 112, and the movable ring 112 can rotate freely to adjust the deflection direction of the first polarizer 21 relative to the second polarizer 22.

[0064] The third embodiment of the present application also discloses a method for identifying a cosmetic product containing a liquid crystal component. Based on the identification method of the first embodiment and the above structure, the identification method of the third embodiment includes:

[0065] S1. Dispose the first polarizer 21 and the second polarizer 22 on two sides of the cosmetic product respectively.

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

[0067] S3. In the observation step, if no color texture is seen, then: rotate any one of the first polarizer 21 and the second polarizer 22 .

[0068] S4, observing whether the light successively passing through the first polarizer 21, the cosmetic product and the second polarizer 22 produces a color texture that changes with the rotation; if so, determining that the cosmetic product contains liquid crystal components; if not, determining that the cosmetic product does not contain liquid crystal components.

[0069] As mentioned above, when the light wave passes through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence, the cosmetic product containing liquid crystal can deflect the light wave and produce the following Figure 6 The colored spots shown prove the presence of liquid crystal components in the cosmetic product to be observed.

[0070] However, by embedding at least one of the first polarizer 21 or the second polarizer 22 into the movable ring 112, the first polarizer 21 and / or the second polarizer 22 can be rotated by rotating the movable ring 112 to adjust the deflection direction of the first polarizer 21 and / or the second polarizer 22. Further, when the deflection direction angle between the first polarizer 21 and the second polarizer 22 changes, the deflection effect of the light will also change. At this time, the liquid crystal in the cosmetic product can deflect the deflected light to present different and gorgeous color effects. By setting it in this way, the user's attention and enthusiasm can be mobilized, thereby further improving the efficiency of anti-counterfeiting identification.

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

[0072] In the first case, the cosmetic product being observed does not contain liquid crystal components, so the deflected light cannot be deflected again. In this case, no matter how the polarizer is rotated, no colored light spots can be observed.

[0073] In the second case, the cosmetic product contains liquid crystal components, but since the deflection directions of the first polarizer 21 and the second polarizer 22 are completely consistent, the light source passing through the first polarizer 21 is redirected by the liquid crystal components and cannot pass through the second polarizer 22, so it is difficult to produce colored light spots. Under this premise, by rotating one of the polarizers to change the deflection direction, the colored light spots can be reappeared, thereby achieving an identification effect.

[0074] Fourth embodiment

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

[0076] As a further improvement of the third embodiment, in the fourth embodiment, referring to Figure 3 As shown, teeth 1121 are also arranged on the outer circumference of the movable ring 112, and the supporting structure 1 further comprises: 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 the first polarizer 21 or the second polarizer 22 needs to be adjusted, by rotating Figure 3 The handle 114 in the middle rotates to drive the gear 113 to rotate, and the rotated gear 113 can drive the movable ring 112 with teeth 1121 around the 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 with the third embodiment in which only a separate movable ring 112 is provided, the rotation of the movable ring 112 driven by the handle 114 and the gear 113 is obviously more convenient for the user to operate. It is worth noting that after the user gets the packaging structure, when he sees the handle 114 provided on the outside, he can directly associate it with the possibility of rotation. Such a setting can guide the user to observe the liquid crystal component in the cosmetic product by rotating the first polarizer 21 or the second polarizer 22.

[0079] It is worth mentioning that although Figure 3 , Figure 4 In the embodiment, the gear 113 and the movable ring 112 are exposed outside the supporting structure 1. Obviously, these structures can also be arranged in the interlayer of the packaging structure.

[0080] In addition, the supporting structure 1 may further include: a deflection direction indicator. The deflection direction indicator is arranged 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, so that the user can grasp the current deflection direction of the first polarizer 21 or the second polarizer 22, making the operation more convenient and improving the interest of the operation.

[0082] Fifth embodiment

[0083] In the previous embodiments, it is necessary to observe the cosmetic products with the help of external light, so it is difficult to observe the cosmetic products in an environment with poor light.

[0084] In view of this, refer to Fig.11 and Fig.12 As shown, the packaging structure further includes: a light source component 3. The light source component 3 is arranged in the supporting structure component 1, and the light irradiated by the light source component 3 sequentially passes through the first polarizer 21, the cosmetic product and the second polarizer 22. The supporting structure is also provided with a first observation hole 13 and a second observation hole 14, and the first observation hole 13 and the second observation hole 14 are located on both sides of the cosmetic product.

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

[0086] When the cosmetic product needs to be observed, the light source component 3 in 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 on the support structure.

[0087] When the light source component 3 is not provided, the packaging structure is placed under natural light, so that the natural light passes through the first polarizer 21, the cosmetic product and the second polarizer 22 in sequence, and a light spot is generated when the cosmetic product contains a liquid crystal component. However, if the weather is bad and the light is weak, it will become difficult to observe the cosmetic product. The light source component 3 can be switched on and off as needed to provide light at any time. Compared with simply relying on natural light, the light of the light source component 3 is more controllable and can adapt to more usage scenarios.

[0088] The first observation hole 13 and the second observation hole 14 are not located on the light path emitted by the light source component 3, and the first polarizer 21 and the second polarizer 22 are not located on the line connecting the first observation hole 13 and the second observation hole 14. Therefore, when observing the cosmetic product through the first observation hole 13 and the second observation hole 14, the original color of the cosmetic product under natural light can be observed. Such a setting facilitates the user to compare the deflected color stripes with each other, making the identification result more rigorous.

[0089] Sixth embodiment

[0090] In the above-mentioned embodiments, the packaging structure is exemplarily represented as an outer packaging box. A transparent container containing cosmetic products is placed in the outer packaging box, so as to realize the identification of the cosmetic products in the container.

[0091] The difference from the above-mentioned embodiments is that in the sixth embodiment of the present application, the supporting structure 1 can also be a container for containing 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, by lifting the container, it is possible to directly observe whether the light passing through the container forms a colored light spot, thereby completing the identification of whether the cosmetic product contains liquid crystal.

[0093] Compared with setting it on the outer packaging box, this design makes the packaging structure simpler and can also reduce costs.

[0094] In addition, two symmetrical slots can also be set on the outer surface of the container, and the first polarizer 21 and the second polarizer 22 can be bent and inserted into the slots respectively to facilitate the detection of cosmetic products in the container. After the detection, the first polarizer 21 and the second polarizer 22 can be retained for the detection of other cosmetic products, thereby reducing the consumption of the first polarizer 21 and the second polarizer 22.

[0095] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
