Description

Technical Field

[0001] The utility model relates to the field of box body anti-counterfeiting, and more specifically, to an anti-counterfeiting cutting edge and a cutting pull ring for a box body. Background Technique

[0002] The anti-counterfeiting of packaging boxes is one of the safeguards for the interests of both buyers and sellers. At present, one of the anti-counterfeiting methods for packaging boxes lies in the opening structure of the packaging box, such that the opening of the packaging box requires the destruction of some irreparable structures, thereby judging whether the packaging box has been opened in advance by whether a specific structure has been damaged.

[0003] The patent with the publication number CN217674356U discloses a cutting pull tab for opening a box body. In the utility model, the cutting piece is designed as a composite cutting piece formed by injection molding of a metal cutting piece and a plastic cutting piece, which significantly improves the strength of the cutting piece without changing the original usage method. Applying pressure to the connecting rib can easily cut off the connecting rib, making it more convenient and fast for users. However, during the injection molding process, the plastic completely covers the metal cutting piece, and the edge part is still made of plastic. Although the overall strength of the cutting piece has increased, the sharpness of the edge part is insufficient. If the connecting rib is not quickly cut off after being pressed, the connecting rib will pull the box body, possibly causing the box body to wrinkle or even crack. Summary of the Utility Model

[0017] The cutting edge structure of the present utility model, which completely wraps the inner sheet body with an outer package body, is improved to a structure where the side of the inner sheet body is exposed. The cutting of the connecting rib is realized by the cutting edge of the inner sheet body to ensure the strength and force of the cutting edge. Since the cutting edge of the inner sheet body needs to be exposed from the outer package body, strip-shaped holes for the exposure of the inner sheet body will be formed on both sides of the outer package body. The existence of the strip-shaped holes will weaken the wrapping force of the outer package body, and the relative position between the outer package body and the inner sheet body may change. Especially during the process of cutting the connecting rib, after the inner sheet body is stressed, the relative position between the inner sheet body and the outer package body is more likely to change. Therefore, the present utility model also improves the structure of the inner sheet body. A first notch is provided on the inner sheet body, which can facilitate the flow of glue during the injection molding process and increase the adhesion area between the glue and the inner sheet body, thereby improving the connection stability between the outer package body and the inner sheet body.

Detailed implementation manner

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0028] The applicant has been committed to the improvement of the anti-counterfeiting structure of the packaging box. Currently, the anti-counterfeiting main structure conceived by the applicant includes a packaging box and a cutting pull ring. The packaging box includes a base and a cover. After placing the item on the base, the cover is closed. As Figure 6 shown, an opening is provided on the base, and the base also has an annular hole as Figure 7 shown. The inner ring wall and the outer ring wall of the annular hole are connected by a connecting rib. The opening is located in the enclosed area of the annular hole. The opening can be used for the clamping piece to pass through. The clamping piece is clamped with the inner wall of the base. A channel for the clamping piece to pass through is also provided on the cover. A splitting piece is provided on the clamping piece. The splitting piece is inserted into the annular hole. When the clamping piece is rotated, the splitting piece cuts the connecting rib, thereby realizing the separation of the cover and the base. Since the separation of the cover and the base requires the destruction of the connecting rib, it can be known whether the package has been opened in advance by whether the connecting rib has been damaged in advance, thereby playing a role in anti-counterfeiting. The applicant applied for a patent with the publication number of CN217674356U on January 20, 2022: a cutting type pull buckle for opening a box body. In this application, the cutting piece is designed as a composite cutting piece formed by injection molding of a metal cutting piece and a plastic cutting piece, which significantly improves the strength of the cutting piece without changing the original usage method. The connecting rib can be easily cut off by applying pressure to the connecting rib. It is more convenient and fast for users to use. However, during the injection molding process, the plastic completely wraps the metal cutting piece, and the blade part is still made of plastic. Although the overall strength of the cutting piece increases, the sharpness of the blade part is insufficient. If the connecting rib is not quickly cut off after being pressed, the connecting rib will pull the box body, which may cause the box body to wrinkle or even crack. Therefore, the applicant further improved the structure of the cutting piece and conceived the technical solutions in the following embodiments.

[0029] Embodiment 1

[0030] AsFigures 1-3 As shown in the figure, a box body anti-counterfeiting cutting edge includes a cutting body, and the cutting body includes an inner sheet body 1 and an outer wrapping body 2. Blade parts 11 are provided on both sides of the inner sheet body 1 in the width direction, and first notches 12 are provided on one side or both sides of the inner sheet body 1 in the length direction; the inner sheet body 1 is embedded in the outer wrapping body 2, and the blade parts 11 of the inner sheet body 1 are exposed from the outer wrapping body 2, and the outer wrapping body 2 is made of plastic material.

[0031] In the specific implementation process, the inner sheet body 1 can be made of metal material, such as Figure 3 As shown in the figure, in this embodiment, by setting the side wall of the inner sheet body 1 as the blade part 11, and then during the process of injection molding the inner sheet body 1 and the outer wrapping body 2 into one body, the blade part 11 is exposed outside the outer wrapping body 2. However, due to the exposure of the blade part 11, a disconnection occurs in the outer wrapping body 2, and the covering stability decreases. The relative position between the outer wrapping body 2 and the inner sheet body 1 may change. Especially during the process of cutting the connecting rib 9, after the inner sheet body 1 is stressed, the relative position between the inner sheet body 1 and the outer wrapping body 2 is more likely to change. Therefore, the structure of the inner sheet body 1 of the present utility model is further improved, as Figure 1 As shown in the figure, a first notch 12 is provided on the inner sheet body 1. Through the first notch 12, it is convenient for the glue to flow during the injection molding process, and the adhesion area between the glue and the inner sheet body 1 is increased, thereby improving the connection stability between the outer wrapping body 2 and the inner sheet body 1. One first notch 12 can be provided, or two can be provided as Figure 1 As shown in the figure, or even multiple notches can be provided on one side of the inner sheet body 1 in the length direction, all of which can improve the connection stability between the outer wrapping body 2 and the inner sheet body 1, and no specific limitation is made in this embodiment.

[0032] Embodiment 2

[0033] In order to achieve the position stability of the two inner sheet bodies 1 during the injection molding process and the overall strength of the cutting edge after injection molding, as Figures 1-3 As shown in the figure, in this embodiment, there are at least two inner sheet bodies 1, which are respectively a first splitting sheet 13 and a second splitting sheet 14; this box body anti-counterfeiting cutting edge includes a connecting body 3. There are two inner sheet bodies 1, and the two inner sheet bodies 1 are connected by the connecting body 3. The connecting body 3 is provided with a second notch 31, and the second notch 31 communicates with the first notch 12 at one end of the inner sheet body 1 close to the connecting body 3. The connecting body 3 is further provided with an opening 32, and the opening 32 is located between the two second notches 31. The connecting body 3 is embedded in the outer wrapping body 2.

[0034] In the specific implementation process, the specifications and sizes of the first splitting piece 13 and the second splitting piece 14 can be exactly the same or can be different. In this embodiment, the cutting edge is set as two inner bodies 1, and then two splitting pieces are formed after injection molding for cutting the connecting ribs 9. If the two inner bodies 1 are not connected into one body through the connecting body 3, it is difficult to ensure the relative positions of the two inner bodies 1 during the injection molding process. Therefore, in this embodiment, the connecting body 3 is provided, as shown in Figure 1 or Figure 2 shown. A second notch 31 is provided on the connecting body 3 and the second notch 31 communicates with the first notch 12, further enhancing the flow of glue at the first notch 12. The settings of the second notch 31 and the opening 32 also make the connection between the outer package 2 and the connecting body 3 more stable. In addition, the opening 32 can also make the cutting edge form an opening 32 for the buckle 7 to be inserted. The structure of the buckle 7 can be referred to Figure 5 shown, which is a fitting in the cutting pull ring previously conceived by the applicant. The structure after its assembly with the cutting edge can be referred to Figure 4 and Figure 6 , and it can be snapped into the opening 32 of the cutting edge. The buckle 7 can be made of a metal material: copper or silver. The metal material can increase the texture of the buckle 7, especially the texture of the pattern on the surface of the buckle 7.

[0035] Embodiment 3

[0036] In order to further avoid wrinkles or cracks on the side wall of the box body, improvements are made on the basis of Embodiment 2, as shown in Figures 1-2 shown. In this embodiment, the width of the first splitting piece 13 is greater than the width of the second splitting piece 14.

[0037] In the specific implementation process, if the widths of the two inner bodies 1 are the same, when opening the box body and rotating the cutting edge, the two inner bodies 1 will contact the connecting ribs 9 at the same time. When the two inner bodies 1 split the connecting ribs 9 at the same time, the two opposite connecting ribs 9 will pull and twist the side wall of the box body at the same time. Since the packaging box is mostly made of paper material, the packaging box is prone to wrinkles or even cracks. Therefore, in this embodiment, the two inner bodies 1 are set to have different widths. After the first splitting piece 13 with a larger width cuts the connecting rib 9, the second splitting piece 14 with a smaller width cuts the other connecting rib 9, and so on until all the connecting ribs 9 are cut off. The connecting ribs 9 can be as shown in Figure 7 shown, and 4 are provided. On the basis of ensuring the connection stability, the number to be cut is reduced, thereby simplifying the operation of opening the packaging box.

[0038] Embodiment 4

[0039] In order to cooperate with the injection molding process of the two inner bodies 1 with different widths, improvements are made on the basis of Embodiment 3, as shown in Figures 1-2As shown in the figure, in this embodiment, the width of the first notch 12 of the first splitting piece 13 is greater than the width of the first notch 12 of the second splitting piece 14, and the width of the second notch 31 is the same as that of the corresponding first notch 12. "Corresponding" refers to the first notch 12 communicating with the second notch 31.

[0040] During the specific implementation process, as Figure 1 shown, a wider first splitting piece 13 is provided with a wider notch to avoid the problem that the width of the first splitting piece 13 is too large while the first notch 12 is too small, resulting in too large a distance between the outer package 2 side at the end of the cutting edge 11 and the outer package 2 side at the end of the first notch 12, and reducing the connection stability between the outer package 2 and the inner sheet body 1.

[0041] Embodiment 5

[0042] As Figures 3-4 and Figure 6 shown, a pull - ring cutting device includes: the box - body anti - forgery cutting edge and the abutting block 4; the abutting block 4 is connected to the box - body anti - forgery cutting edge and is located between the two inner sheet bodies 1. The abutting block 4 includes: a first end portion 41, one end of the first end portion 41 is connected to the box - body anti - forgery cutting edge; a second end portion 42, the other end of the first end portion 41 is connected to the abutting end of the second end portion 42; there is a gap between the side wall at the other end of the first end portion 41 and the edge of the abutting end to form an abutting wall 421 at the abutting end.

[0043] During the specific implementation process, the previously conceived solution of the applicant was to directly clamp the inner wall of the box through the clamping piece 71 at the cutting - edge opening 32. The clamping piece 71 is provided with an outer hook portion 72. Since the packaging box is made of paper material, the clamping piece 71 does not contact the box body during the process of entering the box body. After entering the box body, the fastening nail 7 is inserted into the opening 32 of the cutting edge, and the clamping piece 71 is pushed apart to both sides by the fastening nail 7, so that the clamping piece 71 is clamped with the inner wall of the box body. This structure requires the pull - ring cutting device to be assembled to the box body first, and then the fastening nail 7 is assembled. When assembling the fastening nail 7, a certain pressure needs to be applied, and the packaging box is mostly made of paper material, so the assembly difficulty is relatively high. Therefore, the applicant conceived a structure of providing a claw 8 on the inner side wall of the base as Figure 6 shown. The assembly of the pull - ring cutting device is realized by the abutting of the claw 8 against the side wall of the abutting block 4. At this time, the clamping force comes from the elastically deformable claw 8 instead of the components on the pull - ring cutting device. Thus, the pull - ring cutting device can be pre - assembled with the fastening nail 7, reducing the difficulty of subsequent assembly with the box body as a whole.

[0044] As Figure 6 shown, in this embodiment, an abutting block 4 is provided, and an abutting wall 421 is formed on the side of the second end portion 42 close to the first end portion 41 by the height difference of the side walls at the connection of the first end portion 41 and the second end portion 42 for abutting against the free end of the claw 8.

[0045] Example 6

[0046] In order to reduce the possibility of damage to the fastening pin 7 of the snap piece 71 and improve the movement stability of the fastening pin 7, improvements are made on the basis of Example 5, as Figure 6 shown. In this embodiment, a cavity 411 is provided inside the first end portion 41, and the cavity 411 communicates with the opening 32; the abutting block 4 further includes: a guide rod 43, the inner wall of the first end portion 41 is connected to the guide rod 43, and the free end of the guide rod 43 extends toward the opening 32 and enters the opening 32, and a gap is left between the guide rod 43 and the side wall of the opening 32.

[0047] During the specific implementation process, the fastening pin 7 can be provided with a snap piece 71 as Figure 5 shown. The width of the gap can be greater than the maximum width of the snap piece 71 so that the snap piece 71 can smoothly enter the opening 32, and at the same time, the snap piece 71 has a certain moving space after being pressed by the side wall of the buckle. The maximum width of the snap piece 71 refers to Figure 6 in the cross-sectional view shown, the maximum distance between the upper and lower sides of the snap piece 71, the upper side refers to the side close to the side wall of the opening 32, and the lower side refers to the side close to the guide rod 43.

[0048] During the process of the snap piece 71 sliding along the side wall of the opening 32, if the fastening pin 7 is subjected to a radial force, the deformation of the snap piece 71 is relatively large. By the limitation and guidance of the guide rod 43, while reducing the possibility of damage to the snap piece 71, the movement of the snap piece 71 can be made more stable.

[0049] Exemplarily, the guide rod 43 can be as Figure 6 shown, connected to the bottom wall of the first end portion 41. At the same time, in order to increase the strength of the guide rod 43, the end of the guide rod 43 close to the bottom wall of the first end portion 41 can be larger than the end of the guide rod 43 close to the opening 32.

[0050] Example 7

[0051] In order to facilitate the abutting block 4 to smoothly pass through the area formed by enclosing multiple claws 8, improvements are made on the basis of Example 6, as Figure 6 shown. In this embodiment, the side wall of the second end portion 42 includes: an inclined wall 422, and during the process of the inclined wall 422 extending away from the first end portion 41, it gradually converges inward.

[0052] During the specific implementation process, the claw 8 at least includes an inclined portion that cooperates with the inclined wall 422. During the process of the free end of the inclined portion extending toward the abutting block 4, it gradually converges inward, and the slope of the side wall of the inclined portion close to the first end portion 41 is greater than that of the inclined wall 422.

[0053] As Figure 6As shown, the second end portion 42 and the first end portion 41 are respectively located on both sides of the claw 8. During the process of the end of the second end portion 42 far from the first end portion 41 entering the enclosed space of the claw 8, under the action of the inclined wall 422, the claw 8 gradually opens. When the second end portion 42 completely passes through the enclosed space of the claw 8, the claw 8 resets. With the cooperation between the free end of the claw 8 and the bottom wall of the second end portion 42, the clamping and fixing of the cutting pull ring are realized. The slope of the side wall of the inclined portion close to the first end portion 41 is greater than that of the inclined wall 422 so that the second end portion 42 can push the claw 84 outwards during the forward movement.

[0054] Embodiment 8

[0055] In order to improve the stability when the second end portion 42 passes through the enclosed space of the claw 8, an improvement is made on the basis of Embodiment 7. In this embodiment, the side wall of the second end portion 42 further includes: a horizontal wall 423, the inclined wall 422 is connected to the horizontal wall 423, and the horizontal wall 423 is closer to the first end portion 41 than the inclined wall 422.

[0056] In the specific implementation process, since the slope of the side wall of the inclined portion close to the first end portion 41 is greater than that of the inclined wall 422, the contact between the second end portion 42 and the claw 8 is a line contact, and the rest of the positions are basically in a suspended state, and the moving stability is poor. Therefore, in this embodiment, a horizontal wall 423 is provided on the second end portion 42 to cooperate with the horizontal portion on the claw 8, so that during the process of the second end portion 42 passing through the enclosed space of the claw 8, the horizontal portion and the horizontal wall 423 abut against each other, and through the limit and guidance of the horizontal portion, the moving stability of the abutting block 43 is improved.

[0057] Embodiment 9

[0058] In order to simplify the forming process of the cutting pull ring, an improvement is made on the basis of Embodiment 6, as Figure 6 shown. In this embodiment, the inner wall of the opening 32 near one end of the abutting block 4 extends towards both sides of the opening 32 to form a clamping wall 321, and the clamping wall 321 is connected to the inner wall of the cavity 411.

[0059] In the specific implementation process, as Figure 5 shown, an outer hook portion 72 is provided on the snap fastener 7. In order for the clamping piece 71 to enter the opening 32 more conveniently, the end of the outer hook portion 72 far from the cap body is set as an inclined wall, so that the distance between the free ends of the two clamping pieces 71 is less than the inner diameter of the opening 32, and the free ends of the two clamping pieces 71 are more likely to enter the opening 32. When the inclined wall completely enters the opening 32, since the distance between the outer walls of the two outer hook portions 72 is greater than the inner diameter of the opening 32, the clamping piece 71 is pressed. When the outer hook portion 72 disengages from the opening 32, the clamping piece 71 rebounds, and the clamping piece 71 is clamped with the clamping wall 321. With the cooperation and limitation between the outer hook portion 72 and the clamping wall 321, the snap fastener 7 realizes clamping and fixing.

[0060] Compared with the structure in which the cavity 411 is separated from the opening 32 and the clamping groove is arranged on the side wall of the opening 32 to achieve clamping, in this embodiment, the cavity 411 of the first end portion 41 is communicated with the opening 32, and the clamping of the clamping piece 71 is achieved through the stepped structure formed by the inner walls of the two, which can simplify the forming process of the cutting pull ring.

[0061] Embodiment 10

[0062] In order to facilitate the rotation of the cutting pull ring, improvements are made on the basis of Embodiments 5-9. As Figures 3-4 shown, in this embodiment, it further includes: a grip ring 6, a shaft hole 5 is provided on the side wall of the anti-counterfeiting cutting edge of the box body, and the grip ring 6 is rotationally connected to the shaft hole 5 through a rotating shaft.

[0063] In the specific implementation process, the grip ring 6 is rotationally connected to the cutting edge. When it is necessary to rotate the cutting edge to cut the connecting rib 9, hold the grip ring 6 by hand and apply a rotational force.

[0064] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
