Figure 5 The liquid-containing section 16 is not shown in the diagram. The following is in conjunction with... Figures 1 to 5 Explain the structure of the packaging bottle.

[0029] This invention designs a magnetic packaging bottle, mainly composed of a bottle body 1 and a bottle cap 2. The bottle body 1 is equipped with a first magnetic element, and the bottle cap 2 is equipped with a second magnetic element. The first and second magnetic elements have a magnetic attraction. When the bottle cap 2 approaches the bottle body 1, it is attracted to the bottle body 1, completing the fastening process. When it is necessary to open the bottle cap, simply use appropriate force to pull it out, separating the cap from the bottle body. This achieves convenient opening and closing of the bottle cap, solving the problem of inconvenient closure in traditional packaging bottles. Specifically, the first and second magnetic elements can be a magnet 4 and an iron plate 3, respectively, or two magnets with oppositely arranged irregular magnetic poles. The magnet or iron plate can be placed on the bottle cap 2 or the bottle body 1. The first magnetic element can also be made of cobalt-nickel alloy or ferrite material, which has good magnetic conductivity and corrosion resistance. Multiple layers of parallel thin iron plates can also be used, making them easier to cut and process. Furthermore, the magnetic force between the iron plates and the magnets can be adjusted by adjusting the distance between the iron plates, thus facilitating the optimal tightness of the bottle cap fastening during the assembly process.

[0030] The following description focuses on an embodiment where the first magnetic element is an iron plate 3 and the second magnetic element is a magnet 4, illustrating the implementation of this utility model. With this design, the magnetic force between the bottle cap and the bottle body is more easily controlled by adjusting the thickness of the iron plate and the multi-layered structure, facilitating the adjustment of the cap's adhesion tightness.

[0031] The bottle cap 2 of the packaging bottle adopts a double-layer cap design. The bottle cap 2 is composed of a first cap body 5 and a second cap body 6. The first cap body can be shell-shaped with a hollow structure, and its external shape determines the shape of the bottle cap. The second cap body is completely embedded inside the first cap body, and the two are tightly joined, forming a cavity between them. This double-layer design significantly reduces the weight of the bottle cap. In daily use, whether opening or closing the cap with one hand, the lighter cap significantly reduces hand strain and improves the user experience. The modular cap design also simplifies the structure of the cap components; the first cap body determines the product's appearance, and the second cap body is used to fasten it to the bottle body. A magnet is located inside the aforementioned cavity. During the fastening process of the cap and bottle body, the magnet can attract the metal plate inside the bottle body through the second cap body, assisting in closing the cap.

[0032] In addition, the second cover body can be designed in accordance with the structure of the bottle body to ensure successful engagement of the bottle cap. For example, the top of the bottle body 1 can be provided with a spout 15, a bottle mouth, and other protruding parts, and the middle of the second cover body can be provided with a protruding part 18 with a similar height, which can surround the spout, bottle mouth, and other parts. Therefore, for bottle caps with the same appearance, the first cover body 5 is the same, and by combining the second cover body with different structures with the first cover body, the bottle cap can be adapted to bottle bodies of different shapes, thereby improving the interchangeability of bottle cap parts and reducing production costs.

[0033] To achieve stable connection of the first cover body and the second cover body, a protruding strip 12 is provided on the outer side of the side wall of the rectangular shell of the second cover body, and the inner side of the first cover body is provided with a recess 13 with a matching shape. During assembly, the protruding strip can be precisely inserted into the recess to smoothly complete the fixed connection of the first cover body and the second cover body. This connection method is simple to operate and easy to assemble, which helps to improve production efficiency and ensures stable connection. During transportation or frequent use, it can effectively ensure the stability of the double-layer cover body structure and prevent easy separation.

[0034] As an alternative embodiment, a hollow rectangular shell 8 can be provided at the bottom of the second cover body. The bottom of the rectangular shell is provided with a rectangular opening 9 facing the bottom of the second cover body. Correspondingly, a rectangular boss 10 with the same cross-sectional shape as the rectangular opening is provided on the bottle body 1. When the bottle body and the bottle cap are engaged, the rectangular boss can slide into the rectangular shell through the rectangular opening. The bottle cap and the bottle body are connected by the sliding fit of the rectangular boss and the rectangular shell. The shape of the cross section makes it impossible to rotate relative to each other. A first top plate 11 is provided at the top of the rectangular shell 8, i.e., the side away from the rectangular opening 9, and the magnet 4 is fixedly connected to the side of the first top plate 11 away from the rectangular opening. The magnet 4 can be multiple or arranged circumferentially on the first top plate to make the attractive force between the bottle cap and the bottle body more uniform.

[0035] In actual manufacturing, the magnet can be bonded to the first top plate 11 to ensure that the magnet remains in a stable position and does not displace during multiple uses. The first top plate 11 separates the magnet from the bottle body, thereby ensuring a certain air tightness in the cavity and reducing the oxidation reaction of the magnet in the air. In order to make the installation of the magnet more secure, the magnet 4 can be installed and fixed on the first top plate 11 by the fixing ring 20. The fixing ring can be first fixed on the first top plate by bonding or other methods, and then the magnet can be bonded in the fixing ring; or the fixing ring and the first top plate 11 can be integrally injection molded. This design can improve the installation precision of the magnet, simplify the installation process, and avoid wasting time on manual alignment. The inner circle of the fixing ring 20 can be provided with a plurality of elastic sheets 7 in the circumferential direction, and the inner side of the elastic sheet 7 surrounds a circular installation channel, which has a diameter slightly smaller than that of the magnet. When the magnet is installed, the elastic sheet is slightly deformed, generating a radial clamping force, and the magnet can be fixed in the fixing ring in two ways of bonding and clamping, thereby improving the reliability of the structure.

[0036] The fixing ring can be arranged along the diagonal of the first top plate 11 and disposed on both sides of the protruding portion 18. With this magnet arrangement design, the torque generated by the magnetic force between the bottle cap and the bottle body can be balanced. When the user inserts or pulls out the bottle cap, a stable hand feeling can be obtained, and the trend of additional rotational movement of the bottle cap due to unbalanced magnetic force can be avoided, resulting in unstable hand feeling.

[0037] Optionally, the second cover body can be made of a non-magnetic material, such as common plastics, wood, glass, etc. The key purpose of selecting such materials is to avoid interference with the magnetic force between the magnet and the iron plate, to ensure that the magnetic force can stably and efficiently act on the iron plate of the bottle body, and thus to ensure that the magnetic attraction effect between the bottle cap and the bottle body is not affected. Moreover, plastic materials can be quickly formed into complex shapes through injection molding process, reducing processing cost and difficulty, so that the structure of the second cover body can be more flexibly designed to adapt to different shapes of the bottle body.

[0038] As an optional embodiment, the bottle body can include a nozzle 15, a liquid containing portion 16, and a hollow rectangular boss 10. The nozzle 15 can be screwed to the liquid containing portion 16 for drawing liquid from the liquid containing portion 16. The rectangular boss 10 can be disposed above the liquid containing portion 16. The top of the rectangular boss has a second top plate 14, which serves as a limiting function. Specifically, when the bottle cap is closed with the bottle body, the rectangular boss 10 will slide into the rectangular shell 8 until the second top plate 14 abuts against the first top plate 11.

[0039] In addition, the rectangular boss is used to contact with the rectangular shell at the bottom of the second cover, and magnetic attraction is achieved, so that a matching component such as an iron plate needs to be arranged in the rectangular boss to provide sufficient attraction. Specifically, the second top plate can be embedded with an iron plate 3, or the second top plate is made of a non-magnetic material, and the iron plate is fixedly connected to one side of the second top plate facing the inside of the rectangular boss, which can be achieved by adhesion. In the latter scheme, the rectangular boss and the top of the liquid containing part 16 form a cavity, and the iron plate is arranged in the cavity. At this time, the position of the iron plate is closest to the top of the rectangular boss, and the maximum attraction is generated when the bottle cap approaches the bottle body. As shown in Figure 5 The iron plate is located below the second top plate, that is, in the inside of the rectangular boss. By placing the iron plate in the inside of the rectangular boss, the iron plate is effectively isolated from the outside air and spilled cosmetics, thereby slowing down the rusting speed of the iron plate.

[0040] In order to ensure the stability of the chemical properties of the cosmetics in the liquid containing part, the liquid containing part is often made of glass, and the rectangular boss, which is a special structure with a special shape, is often made of plastic or other materials that are easy to form. The rectangular boss is often adhered to the liquid containing part by glue or the like. However, as the use time increases, the adhesive material is prone to aging, and the risk of the rectangular boss falling off increases. Since the bottle cap is fixed to the rectangular boss by magnetic attraction to obtain fixation, once the rectangular boss falls off, the bottle cap will also fall off; even if it is not completely detached, but the structure is loose, it will also seriously reduce the use experience.

[0041] Alternatively, a through hole 19 is arranged in the middle of the rectangular boss, and the bottom of the spray head 15 has a mounting section 21, which has a cylindrical side surface with a radial dimension greater than the hole diameter of the through hole 19. If the spray head is screwed to the liquid containing part, the mounting section 21 at the bottom of the spray head can abut against the top of the rectangular boss, that is, the upper side of the second top plate during the process of screwing the spray head. This design can assist in fixing the position of the rectangular boss, and ensures that even if the rectangular boss loses the fixing effect of the adhesive material, as long as the spray head is in a screwed state, the position of the rectangular boss can be fixed, and the bottle cap can still be normally buckled and separated from the bottle body. This design improves the durability of the packaging bottle.

[0042] The common structure of the spray head is a slidingly fitted pressing head and a mounting section 21. The mounting section is arranged at the bottom of the spray head and is screwed to the threaded section at the top of the liquid containing part. The outer side surface of the mounting section can be a cylindrical surface, and the second cover of the bottle cap has a similar radial dimension. The middle of the second cover is provided with a protruding part 18, which is adapted to the shape of the spray head. The protruding part is a hollow structure, and the diameter of the internal cavity is slightly larger than the outer diameter of the mounting section of the spray head.

[0043] Since the cross-sectional shape of the rectangular boss is rectangular, the cross-sectional shape of the rectangular shell of the second cap body that matches the rectangular boss when the bottle cap is installed is also rectangular. Therefore, after the bottle cap is buckled with the bottle body, it cannot rotate around the axis of the packaging bottle. The advantage of this structural design is that the connection is firm and not easy to fall off. In actual use, when the consumer closes the cap, he must first manually align the square joint of the bottle cap and the bottle body. If there is a slight deviation, it will not be tightly closed. This operation is very inconvenient in daily life scenarios, such as in a dimly lit environment or when in a hurry, which greatly affects the user experience.

[0044] As an alternative embodiment, a first guide rail 17 can be provided on the outside of the mounting section, the top of the first guide rail 17 has a guide slope, the first guide rail is spirally wound along the axis of the mounting section, and the guide rail protrudes outward from the mounting section. The inside of the protruding part is provided with a second guide rail with the same shape as the first guide rail, the first guide rail and the second guide rail extend along the cylindrical spiral line, and the spiral directions and pitches of the two guide rails are the same. The first guide rail and the second guide rail have guide slopes that slide with each other, and the difference between the cylindrical radii of the spiral lines of the two guide rails is less than the radial width of the guide slope, so as to ensure that the first guide rail and the second guide rail can contact each other during the buckling of the bottle cap.

[0045] The packaging bottle with the first guide rail and the second guide rail design, when the bottle cap is buckled, if the bottle cap is placed askew, that is, the four corners of the rectangular shell and the four corners of the rectangular boss are not aligned, but aligned with the four sides, the first guide rail and the second guide rail will contact, under the action of magnetic attraction between the bottle cap and the bottle body and the gravity of the bottle cap itself, the bottle cap will automatically rotate along the extension direction of the guide rail until the first guide rail and the second guide rail are out of contact, and at this time, the bottle cap is just rotated to the correct buckling position, that is, the four corners of the rectangular shell and the four corners of the rectangular boss are aligned, under the action of magnetic force, the bottle cap continues to fall and completes buckling. When the bottle cap is separated from the bottle body, the bottle cap is pulled out along the axial direction due to the guidance of the matching surface between the bottle cap and the bottle body. At this time, the first guide rail and the second guide rail will be misaligned and will not interfere with the pulling out of the bottle cap. Therefore, the circumferential distribution positions of the first guide rail and the second guide rail should be misaligned. One embodiment is that the outside of the mounting section 21 can be equally spaced with four first guide rails (not shown in the figure) Figure 4The inner side of the convex part is equidistantly distributed with four second guide rails. The height position of the first guide rail and the second guide rail on the mounting section and the convex part is the same. In the top view, the central angle of each first guide rail and second guide rail is 43-45 degrees, the middle part of the first guide rail is aligned with the center of the four corners of the rectangular boss, and the middle part of the second guide rail is aligned with the center of the four sides of the rectangular shell. It can also be the opposite, that is, the middle part of the first guide rail is aligned with the center of the four sides of the rectangular boss, and the middle part of the second guide rail is aligned with the center of the four corners of the rectangular shell. No matter what angle the bottle cap is offset when buckling with the bottle body, the first and second guide rails can automatically guide the bottle cap to rotate to the aligned position, so that it can fall and complete buckling.

[0046] The technical scope of the utility model is not limited to the above-mentioned content in the specification, and those skilled in the art can make various modifications and changes to the above-mentioned embodiments without departing from the technical thought of the utility model, and these modifications and changes should all belong to the scope of the utility model.
