[0022] However, in the prior art, the replacement core structure and / or the box body do not have a positioning structure, making it difficult to fix the replacement core structure in the box body; or, the positioning structure of the replacement core structure and the box body is too complex, making the installation process of the replacement core structure complicated and difficult to operate.

[0023] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0024] This application provides a packaging box, such as Figure 1-5 As shown, the packaging box includes: box body 2 and replacement core structure 1.

[0025] The replacement core structure 1 includes: an inner liner 11, an upper edge 12, and at least two handles 13.

[0026] The upper edge 12 is fixed to the outer periphery of the top opening of the inner liner 11 and extends outward, and at least two handles 13 are provided on the outer side of the upper edge 12 at circumferential intervals.

[0027] The box body 2 includes a first groove 211 with a top opening and at least two positioning grooves 221 disposed on the outer periphery of the first groove 211; the handle portion 13 is configured to be bent downward and detachably confined in the positioning grooves 221, such that the inner liner portion 11 of the replacement core structure 1 is confined in the first groove 211.

[0028] The packaging box provided in this application embodiment has a replacement core structure 1 including an upper edge 12, an inner liner 11, and at least two handles 13. The upper edge 12 is fixed to the outer periphery of the top opening of the inner liner 11 and extends outward. The at least two handles 13 are arranged at circumferential intervals on the outer side of the upper edge 12. The box body 2 includes a first groove 211 with a top opening and at least two positioning grooves 221 arranged on the outer periphery of the first groove 211. The handles 13 can be bent downward and inserted into the positioning grooves 221, realizing a detachable connection between the handles 13 and the positioning grooves 221. When all the handles 13 are inserted into the corresponding positioning grooves 221, the inner liner 11 is located in the first groove 211. Since the first groove 211 can limit the inner liner 11, and the positioning grooves 221 can also limit the handles 13, the replacement core structure 1 can be fixed in the box body. Moreover, this application only requires bending the handle 13 and inserting it into the corresponding positioning groove 221, while placing the inner liner 11 into the first groove 211, to complete the installation of the replacement core structure 1 and the box body 2. The structure is simple and easy to operate.

[0029] In this embodiment, the inner liner 11, the upper edge 12, and the handle 13 are manufactured as a single piece, resulting in a smoother transition at the connection between the inner liner 11 and the upper edge 12. This avoids steps at the connection point that could leave cosmetic residue that cannot be removed, thus improving the user experience. Furthermore, the single-piece molding process simplifies the manufacturing process of the inner liner 11, the upper edge 12, and the handle 13.

[0030] In this embodiment, the handle 13 is printed with relevant information about the replacement core structure 1, including the type of cosmetics contained in the replacement core structure 1, the number of the box 2 that is compatible with the replacement core structure 1, and the number of the replacement core structure 1, so that the replacement core structure 1 can be quickly assembled into different boxes 2.

[0031] In this embodiment of the application, when the replacement core structure 1 is not installed in the box 2, the top surface of the handle portion 13 is coplanar with the top surface of the upper edge portion 12.

[0032] Optionally, in one embodiment of this application, such as Figure 1-2 As shown, in the axial plane of the box 2, the angle between the positioning groove 221 and the top of the box 2 is an acute angle.

[0033] In this embodiment, the angle between the positioning groove 221 and the top of the box 2 in the axial plane of the box 2 is an acute angle. When the handle 13 is bent and inserted into the positioning groove 221, the angle between the handle 13 and the top of the upper edge 12 is also an acute angle. That is, the handle 13 needs to be bent at a greater than 90 degrees from the plane that is on the same plane as the upper edge 12 before it can be inserted into the positioning groove 221. The plane on which the handle 13 is inserted into the positioning groove 221 intersects with the plane on which the top of the box 2 is located but is not perpendicular. Therefore, when the box 2 is flipped up and down, the handle 13 is not easy to fall out of the positioning groove 221, that is, the replacement core structure 1 is not easy to fall out of the box 2, thereby achieving the fixation of the replacement core structure 1 in the box 2.

[0034] Optionally, in one embodiment of this application, such as Figure 1 and Figure 3-5 As shown, at least two handle portions 13 are equally spaced along the circumference of the upper edge portion 12 on the outer side of the upper edge portion 12.

[0035] In this embodiment, at least two handle portions 13 are equally spaced along the circumference of the upper edge portion 12 on the outer side of the upper edge portion 12, and at least two positioning slots 221 are equally spaced along the circumference of the box body 2 on the outer periphery of the first groove 221. Since the spacing between each handle portion 13 is equal, when the replacement core structure 1 is installed into the box body 2, any handle portion 13 can be inserted into any positioning slot 221. There will be no problem that a certain handle portion 13 is inserted into the wrong positioning slot 221, causing another handle portion 13 to be unable to be inserted into another positioning slot 221. The operation is simple and the user experience is improved.

[0036] Optionally, in some embodiments, the number of positioning slots 221 in the housing 2 may be greater than the number of handle parts 13 in the replacement core structure 1, as long as all handle parts 13 can be inserted into the corresponding positioning slots 221. The number of positioning slots 221 in the housing 2 may also be equal to the number of handle parts 13 in the replacement core structure 1, with each handle part 13 and each positioning slot 221 being set in a one-to-one correspondence.

[0037] Optionally, in some embodiments, the number of handle portions 13 includes an odd number of not less than 3, and the odd number of handle portions 13 are equally spaced along the circumference of the upper edge portion 12 on the outer side of the upper edge portion 12. In some embodiments, the number of handle portions 13 includes an even number of not less than 2, and the even number of handle portions 13 are equally spaced along the circumference of the upper edge portion 12 on the outer side of the upper edge portion 12.

[0038] Optionally, in one embodiment of this application, such as Figure 1 and Figure 3-5 As shown, there is an even number of handles 13, and the even number of handles 13 are symmetrically arranged on the outer side of the upper edge 12 along the circumference of the upper edge 12.

[0039] In one specific embodiment of this application, the number of handle parts 13 includes two, which are symmetrically arranged on the outer side of the upper edge 12 along the circumference. It should be noted that in this embodiment of the application, when the number of handle parts 13 is even, the number of handle parts 13 can also be four, six, etc. The number of handle parts 13 is set according to the specific actual situation, and is not limited in this application.

[0040] Optionally, in one embodiment of this application, such as Figure 4-5 As shown, the upper edge portion 12 includes a first portion 121, a second groove 122 and a second portion 123 distributed from the inside out. The opening orientation of the second groove 122 is the same as the opening orientation of the inner liner portion 11. The annular second groove 122 is arranged circumferentially along the upper edge portion 12.

[0041] In this embodiment, the unused replacement core structure 1 uses an aluminum-plastic film or similar sealing film to seal the opening of the inner liner 11. An annular second groove 122 is arranged circumferentially along the upper edge 12. Within the plane of the upper edge 12, the second groove 122 is located closer to the outer edge of the upper edge 12, making the width of the first part 121 greater than the width of the second part 123. This increases the contact area between the sealing film of the inner liner 11 opening and the first part 121, improving the sealing effect of the opening film. Simultaneously, the opening film does not completely cover the upper edge 12, ensuring that when the opening film of the inner liner 11 is torn open, it will not lift the film covering the top surface of the second part 123, thus preventing the film covering the top surface of the first part 121 from being lifted, thereby maintaining the integrity of the upper edge 12 structure. It should be noted that the width of the first part 121 refers to the width of the annulus of the first part 121, and the width of the second part 123 refers to the width of the annulus of the second part 123.

[0042] Optionally, in one embodiment of this application, such as Figure 4-5 As shown, at least two handle portions 13 are equally spaced along the circumference of the second portion 123 on the outer side of the second portion 123.

[0043] In this embodiment, the number of handle portions 13 can be odd. When the number is odd, the number of handle portions 13 is at least three. The odd number of handle portions 13 are evenly spaced on the outer side of the second part 123 along the circumference of the upper edge portion 12. The number of handle portions 12 can also be even. When the number is even, the number of handle portions 13 is at least two. The even number of handle portions 13 are evenly spaced on the outer side of the second part 123 along the circumference of the upper edge portion 12.

[0044] Optionally, in one embodiment of this application, such as Figure 4-5As shown, a third groove 131 is provided on the handle portion 13. The extension direction of the third groove 131 is tangent to the outer periphery of the contacting upper edge portion 12, and the third groove 131 partially overlaps with the second groove 122.

[0045] In this embodiment, a third groove 131 is provided on the handle portion 13, and the extending direction of the third groove 131 is tangent to the outer periphery of the contacting upper edge portion 12. Thus, when the handle portion 13 is bent, the handle portion 13 can be easily bent along the position where the third groove 131 is located, so that the surface of the bent part of the handle portion 13 is flat and will not drive the upper edge portion 12 that is close to the handle portion 13. This avoids the problem that when the handle portion 13 is bent, the upper edge portion 12 that is close to the handle portion 13 is driven due to the unclear bending point, resulting in an uneven surface of the upper edge portion 12 that is close to the handle portion 13.

[0046] Furthermore, since the handle 13 can be bent along the third groove 131, the surface of the bent part of the handle 13 is flat and the surface of the upper edge 12 is flat, so that the bent part fits more closely with the edge of the top of the box body 2 and the upper edge 12 fits more closely with the top of the box body 2.

[0047] Optionally, in one embodiment of this application, such as Figure 4-5 As shown, based on the plane where the bottom of the inner liner 11 is located, the top surface of the second part 123 of the upper edge 12 is lower than the top surface of the first part 121 of the upper edge 123.

[0048] In this embodiment, based on the plane where the bottom of the inner liner 11 is located, the top surface of the second part 123 of the upper edge 12 is lower than the top surface of the first part 121 of the upper edge 123. The upper edge 12 includes a film, which is disposed on the top surface layer of the upper edge 12. When an aluminum-plastic film or other sealing film seals the opening of the inner liner 11, the edge of the sealing film is fixed to the film on the top surface layer of the first part 121 of the upper edge 12, while the edge of the sealing film is not fixed to the film on the top surface layer of the second part 123 of the upper edge 12, causing the sealing film of the opening of the inner liner 11 to separate from the film on the top surface layer of the second part 123. Since the film on the top surface layer of the second part 123 and the film on the top surface layer of the first part 121 are the same piece, when the sealing film of the opening of the inner liner 11 is torn open, it will not pull up the film on the top surface layer of the second part 123. During the tearing process of the sealing film, an upward separation will occur. The upward force acts on the first part 121 to lift the film on the top surface of the first part 121. At the same time, the film on the top surface of the second part 123, which is connected to the film on the top surface of the first part 121, generates a downward force. This downward force acts on the first part 121 to prevent the film on the top surface of the first part 121 from being lifted. The effects of the two forces cancel each other out, thereby preventing the film on the top surface of the first part 121 from being lifted. Therefore, when the opening seal of the inner liner 11 is torn open, the film on the top surface of the upper edge 12 will not be lifted, ensuring the integrity of the structure of the upper edge 12.

[0049] Optionally, in one embodiment of this application, such as Figure 1-3 As shown, the box body 2 includes a main body 21 and a peripheral part 22 surrounding the main body 21.

[0050] The first groove 211 is formed in the main body 21, and the positioning groove 221 is formed in the peripheral part 22.

[0051] Based on the plane where the bottom of the inner liner 11 is located, the top surface of the main body 21 of the box body 2 is higher than the top surface of the peripheral part 22 of the box body 1.

[0052] In this embodiment of the application, the first groove 211 of the box body 2 is used to limit the inner liner 1 of the replacement core structure 1, and the positioning groove 211 of the box body 2 is used to limit the handle 13 of the replacement core structure 1, thereby fixing the replacement core structure 1 in the box body 2.

[0053] In this embodiment, the positioning groove 221 is located in the area where the peripheral part 22 and the main body 21 meet. Based on the plane where the top of the inner liner 11 is located, the top surface of the main body 21 is higher than the top surface of the peripheral part 22. Therefore, during the process of inserting the bent handle part 13 into the positioning groove 221, the top surface of the peripheral part 22 will not interfere with the handle part 13, making it easier for the handle part 13 to be inserted into the positioning groove 221.

[0054] Optionally, in one embodiment of this application, such as Figure 1-3 As shown, the inner liner 11 is gap-fitted into the first groove 211; or, the inner liner 11 is interference-fitted into the first groove 211.

[0055] In this embodiment, the cross-section of the inner liner 11 in the plane perpendicular to the upper edge 12 includes a semi-ellipse, a circle, or a U-shape, etc., and the cross-section below the groove 211 includes a semi-ellipse, a circle, or a U-shape, etc.

[0056] In one specific embodiment of this application, the cross-sectional shape of the inner liner 11 in the plane perpendicular to the upper edge 12 includes a semi-elliptical shape. When the cross-sectional shape of the first groove 211 includes a semi-elliptical shape, the major axis dimension of the inner liner 11 is not greater than the major axis dimension of the first groove 211, and the minor axis dimension of the inner liner 11 is not greater than the minor axis dimension of the first groove 211. The inner liner 11 is loosely fitted into the first groove 211. In this structure, the replacement core structure 1 is fixed in the box body 2 by limiting the handle portion 13 in the positioning groove 221.

[0057] In one specific embodiment of this application, the cross-sectional shape of the inner liner 11 in the plane perpendicular to the upper edge 12 includes a semi-elliptical shape. When the cross-sectional shape of the first groove 211 includes a circle, the minor axis of the inner liner 11 is equal to the radius of the first groove 211, and the major axis of the inner liner 11 is greater than the radius of the first groove 211. Thus, when the inner liner 11 is placed in the first groove 211, the inner liner 11 and the first groove 211 are in an interference fit. In this structure, the limiting effect between the handle 13 and the positioning groove 221 and the limiting effect between the inner liner 11 and the first groove 211 are used to fix the replacement core structure 1 in the box body 2.

[0058] By applying the embodiments of this application, at least the following beneficial effects can be achieved: 1. The packaging box provided in this application embodiment includes a replacement core structure 1 comprising an upper edge 12, an inner liner 11, and at least two handles 13. The upper edge 12 is fixed to the outer periphery of the top opening of the inner liner 11 and extends outward. The at least two handles 13 are arranged at circumferential intervals on the outer side of the upper edge 12. The box body 2 includes a first groove 211 with a top opening and at least two positioning grooves 221 disposed on the outer periphery of the first groove 211. The handles 13 can be bent downward and inserted into the positioning grooves 221, thereby achieving a detachable connection between the handles 13 and the positioning grooves 221. When all the handles 13 are inserted into the corresponding positioning grooves 221, the inner liner 11 is located in the first groove 211. Since the first groove 211 can limit the inner liner 11, and the positioning grooves 221 can also limit the handles 13, the replacement core structure 1 can be fixed in the box body. Moreover, this application only requires bending the handle 13 and inserting it into the corresponding positioning groove 221, while placing the inner liner 11 into the first groove 211, to complete the installation of the replacement core structure 1 and the box body 2. The structure is simple and easy to operate.
