Description

Technical Field

[0001] This utility model relates to a packaging box. Background Technology

[0002] Plane mirror imaging follows the law of reflection, where the angle of incidence equals the angle of reflection. When light propagates between parallel mirrors, each reflection generates a symmetrical virtual image. If the mirrors are parallel and of sufficient size, light can theoretically reflect an infinite number of times, forming an infinitely nested sequence of images, known as infinite reflection. The essence of infinite reflection is the geometric representation of the cyclic path of light within an ideal parallel reflecting interface and the conservation of energy. Its realization depends on the flatness, parallelism, and reflectivity of the mirrors, but real-world attenuation makes "infinity" merely a visual approximation.

[0003] Display is a fundamental function of packaging. Visual perception theory indicates that the human brain has a rapid response to color and pattern; therefore, the visual appeal of packaging design directly affects a product's attractiveness. With increasing market competition, consumers have higher and higher demands for the visual experience of products. However, existing packaging boxes can only display the physical appearance, lacking creativity and appeal. Utility Model Content

[0004] This invention aims to give packaging boxes a unique visual effect through the application of the principle of infinite reflection optics, which can more effectively attract consumers' attention. To solve the above-mentioned technical problems, the technical solution adopted by this invention is a packaging box, including a box body for loading objects, characterized in that a semi-reflective mirror is provided on side A of the box body, and a reflector is provided on side B of the box body. Sides A and B are located on opposite sides of the object; the reflector is selected from a specular reflector or a semi-reflective mirror.

[0005] In one embodiment, the housing is equipped with a light-emitting component. This provides illumination to the space or object inside the housing, compensating for insufficient or attenuated light, thus making the virtual image in the infinite reflection phenomenon clearer and increasing the number of virtual images.

[0006] In one embodiment, the box is partially or entirely transparent or semi-transparent, allowing for direct observation of the infinite reflection phenomenon of the object without opening the box.

[0007] In one embodiment, side A of the housing is formed by a semi-reflective lens.

[0008] In one embodiment, the housing consists of several sets of opposing semi-reflective lenses.

[0009] In one embodiment, the angle between the mirror surfaces of the A-side semi-reflective lens and the B-side reflector ranges from 0 to 20 degrees. Furthermore, the A-side semi-reflective lens and / or the B-side reflector are mounted on a swing shaft, and a driving component causes the A-side semi-reflective lens and / or the B-side reflector to swing. This allows for different mirror angles to be presented at any time, forming a dynamic reflection system and further enriching the visual effect.

[0010] Preferably, the shape of the box is selected from tetrahedron, hexahedron, octahedron, cylinder, and multifaceted cube.

[0011] Preferably, the mirror structure of the semi-reflective mirror and / or the reflector is selected from a plane mirror, a curved mirror, or an irregularly shaped mirror.

[0012] In one embodiment, the object contained in the box is a birthday cake or a birthday gift.

[0013] The beneficial effects of this utility model are that, by adopting the above-mentioned solution and creating a unique visual effect through optical principles, it can significantly enhance the product's attractiveness, making it stand out among many similar products, attracting consumers' attention, and improving the product's market competitiveness. Consumers can appreciate the visual effect of infinite reflection of the packaged object, increasing the product's interest and visual appeal, and enhancing consumers' desire to purchase. This utility model has a simple structure, is easy to manufacture and use, has low cost, and has high market promotion value.

[0030] Example 1: See Appendix Figure 1-2 This illustrates a specific structure of the present invention. The packaging box includes a box body for holding an object—a birthday cake. A first semi-reflective lens 3 is provided on side A of the box body 1, and a reflector 4 is provided on side B of the box body 1. Sides A and B are located on opposite sides of the birthday cake. The reflector 4 can be a mirror or a second semi-reflective lens. In this example, the box body 1 includes a light-emitting component—a switch-controlled light strip 5. The light-emitting component can be installed inside or outside the box body 1, sufficient to provide illumination for the space or object inside the box, compensating for insufficient or attenuated light to make the virtual image in the infinite reflection phenomenon clearer and more numerous. In well-lit environments, the light-emitting component may not be necessary.

[0031] In the example, the box 1 can be entirely transparent or semi-transparent. For instance, sides A and B can be semi-reflective lenses, while the other two sides and the lid (not shown in the figure) are transparent, so that the infinite reflection of the birthday cake, candlelight, and cake fireworks can be directly observed without opening the box, effectively enhancing the atmosphere of the birthday party.

[0032] In other embodiments, side A, side B, and the other two sides may also be semi-reflective mirrors.

[0033] The box 1 can also be partially transparent, such as only side A being a semi-reflective mirror, side B being an opaque mirror, and the rest being opaque. When an observer looks inside the box through the first semi-reflective mirror 3, they can see the virtual image of the cake being reflected repeatedly, creating the visual effect of "countless cakes".

[0034] In the example, side A of the housing 1 is directly formed by the first semi-reflective lens 3. In other embodiments, a transparent side can also be provided on side A of the housing 1, and the first semi-reflective lens 3 can be mounted on this side.

[0035] In one embodiment, the reflectivity of the semi-reflective mirror ranges from 20% to 80%, and the corresponding transmittance ranges from 80% to 20%. Based on the designed packaging visual effect, the reflectivity and transmittance of the semi-reflective mirror are adjusted within the range of values ​​to control the sharpness and number of virtual images and the distance between virtual images.

[0036] Existing technologies have achieved precise control of the reflectivity and transmittance of semi-reflective mirrors through coating processes. By coating the lens surface with corresponding multi-layered thin films, the desired reflectivity and transmittance ratio can be achieved. For example, a semi-reflective mirror with a reflectivity of 30% and a transmittance of 70% can be designed by adjusting the thickness and material of the thin films. In this example, the reflectivity and transmittance of the semi-reflective mirror can be adjusted as needed to achieve the designed packaging visual effect. The sum of the reflectivity and transmittance of the semi-reflective mirror is 100%, and they are inversely related. By adjusting the ratio of reflectivity to transmittance, the sharpness and number of virtual images and the distance between them can be controlled as needed. According to our experiments, the numerical range that best demonstrates the desired visual effect in packaging applications is: a reflectivity range of 20% to 80% for the semi-reflective mirror, and a corresponding transmittance range of 80% to 20%. The specific relationships within this numerical range can be seen in the actual data and relative effect descriptions shown in the table below:

[0037] Reflectivity (R) Transmittance (T) Virtual image sharpness Number of virtual images Distance between virtual images 20％ 80％ Highest least recent 30％ 70％ high few close 40％ 60％ Medium+ medium- medium- 50％ 50％ medium medium medium 60％ 40％ medium- Medium+ Medium+ 70％ 30％ Low many Far 80％ 20％ lowest most Farthest

[0038] Example 2 ： See appendix Figure 3This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the reflector 201 on side B of the box and the semi-reflective lens 205 on side A may not be parallel.

[0039] In existing theories of infinite reflection optics, light rays should propagate between parallel mirrors. That is, the angle between the two planes (called the mirror angle) of the semi-reflective mirror on side A and the mirror on side B should be zero. In practice, we have found that in packaging applications, the mirror angle can also be non-zero. A certain degree of mirror angle not only creates the infinite reflection effect required for packaging but also enriches the visual effect of the packaging design. In the example, the mirror angle between the semi-reflective mirror 205 on side A and the mirror 201 on side B ranges from 0 to 20 degrees. In the example, the mirror 201 on side B of the box is mounted on a swing shaft 202. The upper end of the swing shaft 202 is mounted in a bearing seat 204, and the lower end is connected to a drive motor 203. The drive motor 203 drives the mirror 201 to swing. When the mirror 201 swings, it presents different mirror angles with the semi-reflective mirror 205, forming a dynamic reflection system, further enriching the visual effect.

[0040] Example 3: See Appendix Figure 4 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the box body is a hexahedron, and the six sides can be divided into three corresponding groups of opposing sides: first A side 301 and first B side 302, second A side 303 and second B side 304, and third A side 305 and third B side 306. Each group of opposing sides is respectively provided with a semi-reflective lens and a reflector, and all the reflectors can be semi-reflective lenses.

[0041] Example 4: See Appendix Figure 5 This reflects another specific structure of the present invention. The difference from Embodiment 3 is that the box body is octahedral.

[0042] Example 5: See Appendix Figure 6 This reflects another specific structure of the present invention. The difference from Embodiment 3 is that the box body is a multi-faceted cube, composed of upper and lower boxes, which can be opened at the splicing part 503. The multiple sets of opposite sides corresponding to the multi-faceted cube can be divided into quadrilateral opposite sides 501 and triangular opposite sides 502. In the triangular opposite sides 502, the vertices of the triangles on side A and side B are reversed, which does not affect the achievement of the purpose of the invention. The reflectors are all semi-reflective mirrors for better effect.

[0043] Example 6 ： See appendix Figure 7This illustrates another specific structure of the present invention. The difference from Embodiment 1 is that the box body is cylindrical, and both the semi-reflective mirror 601 on side A and the reflector 602 on side B are semi-circular arcs. The two semi-circular arcs are joined together to form a cylinder, which is then mounted on the base 603. Using a semi-reflective mirror provides better performance.

[0044] Example 7: See Appendix Figure 8 This illustrates another specific structure of the present invention. The difference from Embodiment 1 is that both the semi-reflective mirror 701 on side A and the reflector 702 on side B are curved mirror surfaces. Using a semi-reflective mirror provides better performance. In this example, the concave portions of the two curved mirror surfaces are arranged opposite each other; in other embodiments, the convex portions of the two curved mirror surfaces may be arranged opposite each other, or the convex portion of one curved mirror surface may be arranged opposite the concave portion of another curved mirror surface.

[0045] Example 8: See Appendix Figure 9 This illustrates another specific structure of the present invention. The difference from Embodiment 1 is that the semi-reflective mirror 801 on side A and the reflector 802 on side B are both irregularly shaped mirrors mounted on the base 803, creating an effect similar to a funhouse mirror. The box in this example is not enclosed.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention.
