Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a buffer packaging box with an anti-theft function. Background Art

[0002] With the popularity of online shopping, express delivery has developed rapidly. When fragile items or some high-precision equipment with weak impact resistance need to be transported, it is usually necessary to use special packaging materials or put protective devices in the packaging box to protect the products to be transported, so as to reduce the collision between the products and the packaging box during transportation. When sealing the box, it is usually connected by gluing or alternate cardboard clipping. The use of plastic tape increases the cost, and the gluing process requires additional steps, which wastes the assembly time of the carton and reduces the speed of the carton production. When unpacking, it is usually necessary to prepare auxiliary tools such as knives and scissors to complete it, which is both dangerous and inconvenient.

[0003] In addition, most of the existing tape-free cartons do not have anti-theft functions. They can be opened without damage by bare hands, and the items inside can be taken away or replaced at will, and then the lid can be restored to its original state. It is difficult to judge whether the lid has been opened from the appearance alone, and the safety of the items in the box cannot be guaranteed. The anti-theft function here means that the box cannot be opened without destroying the structure of the box, and the damaged parts cannot be restored once the box is opened. At present, the design structure of cartons with such anti-theft functions is relatively complex, and the anti-theft device occupies too much effective space in the box.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figure 1 and Figure 2 The utility model discloses a buffer packaging box with an anti-theft function, which includes a box body 1 and a box cover 3; wherein a buffer assembly 2 is provided in the box body 1, specifically, the buffer assembly 2 includes a pad 21 and a plurality of support plates 22, and one end of the support plate 22 is connected to the pad 21, and the other end of the support plate 22 is against the inner wall of the box body 1, so that a buffer interval is formed between the pad 21 and the inner wall of the box body 1.

[0034] See also Figure 2The box body 1 has an opening 10, and the box cover 3 is rotatably connected to the opening 10, and the box cover 3 is used to open or cover the opening 10 during the rotation process. The box cover 3 includes a main board 31 and a folding plate 32, one side of the main board 31 is rotatably connected to one side of the opening 10, so that the box cover 3 can rotate relative to the box body 1; the other side of the main board 31 is rotatably connected to the folding plate 32, and the folding plate 32 is used to fit on one side of the box body 1 when the box cover 3 covers the opening 10. It is worth noting that the box cover 3 is provided with a first connecting portion 33, and the box body 1 is provided with a second connecting portion 11, and the first connecting portion 33 is used to be locked and connected with the second connecting portion 11 when the box cover 3 covers the opening 10. In addition, the box cover 3 is provided with a separation portion 34, and the separation portion 34 is used to separate from the box cover 3 under the action of an external force.

[0035] Based on this structure, when using the packaging box of the utility model, when packaging the product, the product can be limited on the pad 21. Specifically, the product can be glued to the pad 21 or a limiting groove can be set on the pad 21, and the product can be placed in the limiting groove. When sealing the box, the box cover 3 is rotated toward the box body 1 and the first connecting part 33 on the box cover 3 is locked and connected with the second connecting part 11 on the box body 1 to seal the opening 10. When opening the box, the locking effect between the box body 1 and the box cover 3 is released by separating the separation part 34 on the box cover 3, and the box cover 3 is rotated away from the box body 1 to open the opening 10, so that the product can be taken in and out.

[0036] Among them, the support plate 22 is arranged below the pad 21 and connected to the outer periphery of the pad 21, and the end of the support plate 22 away from the pad 21 is against the angle formed by the bottom wall and the side wall of the box body 1, and the support plate 22 is gradually inclined from the end close to the pad 21 to the end away from the pad 21, thereby forming a buffer interval at the bottom and around the pad 21, and the support plate 22 can support the pad 21 with the help of the inner wall of the box body 1. When the box body 1 falls or is hit by foreign objects during transportation or movement, the box body 1 can absorb the external impact force through the buffer interval, slow down or block the transmission of the impact force to the product, and protect the product.

[0037] It should be noted that when the box is sealed, the box body 1 and the box cover 3 are locked and connected through the first connection part 33 and the second connection part 11. The locked connection here means that the first connection part 33 and the second connection part 11 are self-locking when connected. The first connection part 33 and the second connection part 11 cannot be unlocked from the outside of the box body 1. The box can only be opened by destroying the structure of the first connection part 33 and the second connection part 11, or destroying other parts of the packaging box. Therefore, once the packaging box has been opened, damage will be formed on the surface of the packaging box, and it is clear at a glance whether the packaging box has been opened, which plays an anti-theft role.

[0038] See also Figure 2, the present application sets a separation portion 34 on the box cover 3 to realize barehanded opening of the box. Specifically, the separation portion 34 is used to separate from the box cover 3 under the action of external force, and in the process of separation, the box cover 3 is divided into two parts, one part of the box cover 3 is still rotatably connected to one side of the opening 10 and can rotate relative to the opening 10; the other part of the box cover 3 is connected to the side of the box body 1 through the first connection portion 33 and the second connection portion 11. Therefore, the user can break the box cover 3 from the separation portion 34 to open the opening 10 without using tools, and the box opening is convenient.

[0039] In addition, when the box cover 3 seals the opening 10, the main board 31 covers the opening 10, and the folding plate 32 is attached to one side of the box body 1. The corner connection between the main board 31 and the folding plate 32 can block the gap between the bottom of the main board 31 and the upper end of the opening 10, preventing rainwater from entering the packaging box through the gap at the upper end of the opening 10 during transportation.

[0040] Furthermore, the first connection part 33 includes a self-locking tongue, the second connection part 11 includes a slot, and the self-locking tongue is used to be squeezed by the box body 1 during the process of plugging with the slot and deformed so that the self-locking tongue can be plugged into the slot. After the self-locking tongue returns to its original shape, it abuts against the box body 1 so that the self-locking tongue is locked in the slot.

[0041] Based on this structure, the packaging box of the present application can be a corrugated box, a cardboard box, etc., and the self-locking tongue and the slot are integrally formed on the packaging box. When sealing the box, the box cover 3 is rotated toward the box body 1, and the self-locking tongue is inserted and locked into the slot under the action of external force. Specifically, the self-locking tongue includes a first plug-in section and a second plug-in section along the plug-in direction, and the first plug-in section is located outside the second plug-in section. Among them, the length of the first plug-in section in the length direction of the slot is greater than the length of the slot, and the length of the second plug-in section in the length direction of the slot is not greater than the length of the slot.

[0042] When the self-locking tongue is plugged into the slot, the first plug-in section will be squeezed by the cardboard around the slot during the process of being inserted into the slot by external force, so that the first plug-in section can be deformed along the thickness direction of the slot, thereby reducing the length of the first plug-in section in the length direction of the slot, so that the first plug-in section can be inserted into the box body 1 through the slot after deformation. Since the length of the second plug-in section in the length direction of the slot is less than the length of the slot, the second plug-in section can be directly inserted into the slot. Among them, since the packaging box of the present application is made of cardboard material, the first plug-in section and the slot both have a certain elastic deformation ability. The first plug-in section can return to its original shape after being not squeezed by the slot, and after returning to its original shape, it abuts against the inner wall of the box body 1, thereby being locked inside the box body 1.

[0043] The length of the first plug-in section in the length direction of the slot should not be set too large to avoid excessive squeezing and damage to the first plug-in section or the slot, resulting in the first plug-in section being unable to return to its original shape in the box 1, causing the locking effect of the self-locking tongue and the slot to fail.

[0044] Thus, the box cover 3 can be locked with the slot by the self-locking tongue, eliminating the need to use plastic tape to seal the box, which not only shortens the sealing time, but also saves costs and reduces pollution. The self-locking tongue is locked inside the box body 1, so the locking structure between the self-locking tongue and the slot cannot be unlocked from outside the packaging box, and can only be unlocked by destroying the packaging box, which can play an anti-theft role.

[0045] In addition, the first connection part 33 may also include a main plug tongue and a secondary plug tongue, wherein the secondary plug tongue is connected to one side of the main plug tongue along the length direction, and the secondary plug tongue is folded to one side of the main plug tongue along the thickness direction, and the secondary plug tongue and the main plug tongue present a zigzag shape when not under force; the second connection part 11 includes a slot. When the first connection part 33 is connected to the second connection part 11, an external force is used to press the secondary plug tongue and the main plug tongue in the thickness direction into a straight line, and then the secondary plug tongue is directly inserted into the slot. After the external force is removed, the secondary plug tongue and the main plug tongue are separated from each other in the box body 1 and present a zigzag shape again. At this time, the main plug tongue is connected to the slot, and the secondary plug tongue is against the inner wall of the box body 1, and the first connection part 33 is locked inside the box body 1.

[0046] Further, the first connection portion 33 includes two self-locking tongues, and the two self-locking tongues are arranged at intervals along the length direction of the box cover 3. Correspondingly, the second connection portion 11 includes two slots, and the two slots are arranged one-to-one with the two self-locking tongues.

[0047] Thus, the box cover 3 is connected to the box body 1 by locking the two self-locking tongues in the two slots, which can enhance the connection strength between the box cover 3 and the box body 1, and further press the box cover 3 on the box body 1 to prevent the product from falling out. In addition, the one-step unlocking can be achieved by separating the separation part 34 from the box cover 3.

[0048] Furthermore, guide surfaces 331 are provided on both sides of the self-locking tongue, and the guide surfaces 331 are used to guide the self-locking tongue to be inserted into the slot when the self-locking tongue is plugged and matched with the slot.

[0049] The self-locking tongue includes a first plug-in section and a second plug-in section, and guide surfaces 331 are arranged on both sides of the first plug-in section; since the first plug-in section is relatively long in the length direction of the slot, it is not easy for the first plug-in section to be plugged into the slot. Therefore, the length of the front end of the first plug-in section is set to be relatively small, and the length is gradually increased from the front end to the rear end, so that inclined guide surfaces 331 can be formed on both sides of the first plug-in section, and the guide surfaces 331 can guide the first plug-in section to be inserted into the slot.

[0050] In addition, after the first plug-in section is locked in the box body 1, the rear end of the first plug-in section (where the length is the largest) abuts against the inner wall of the box body 1, thereby preventing the first connecting portion 33 from being separated from the second connecting portion 11.

[0051] Furthermore, the first connection portion 33 is disposed on a side of the folding plate 32 away from the main board 31 , and the second connection portion 11 is disposed on a side of the box body 1 , and there is a gap between the second connection portion 11 and the upper end of the box body 1 .

[0052] Based on this structure, when sealing the box, the box cover 3 is first rotated toward the box body 1, so that the main board 31 of the box cover 3 covers the opening 10 of the box body 1, and the folding plate 32 is attached to the side of the box body 1. When the folding plate 32 is attached to the side of the box body 1, the first connecting portion 33 on the folding plate 32 can be connected to the second connecting portion 11 on the side of the box body 1.

[0053] Since there is a gap between the second connection part 11 and the upper end of the box body 1, the fitting area between the folding plate 32 and the side of the box body 1 can be ensured, and the folding plate 32 can block the opening 10 of the box body 1 from the side of the box body 1 to prevent rainwater from entering the box from the gap of the opening 10. In addition, the connection between the first connection part 33 and the second connection part 11 can further press the main board 31 of the box body 1 against the opening 10, and press the folding plate 32 against the side of the box body 1 to ensure the tightness of the box sealing.

[0054] Further, the separation portion 34 is a tear strip, and the tear strip extends along the length direction of the box cover 3 and penetrates the box cover 3 .

[0055] Wherein, the tear strip can be arranged on the main board 31 or on the folding plate 32. When the tear strip is arranged on the main board 31, the tear strip is separated from the main board 31 under the action of external force, and the main board 31 is divided into two plates, one of which is rotatably connected to the box body 1, and the other plate is connected to the side of the box body 1 through the folding plate 32, and the opening 10 can be opened after the two plates are opened separately. When the tear strip is arranged on the folding plate 32 or on the side of the folding plate 32 close to the main board 31, the tear strip is separated from the folding plate 32 under the action of external force, and the main board 31 is divided from the folding plate 32, wherein the main board 31 can rotate relative to the box body 1 to open the opening 10, and the folding plate 32 is connected to the side of the box body 1 through the locking connection. In this case, the main board 31 remains intact, and the opening 10 can be normally covered in subsequent use, so that the packaging box can be recycled.

[0056] More specifically, the tear strip can be a long strip, which is integrally formed with the box cover 3 and connected to the main board 31 or the folding plate 32 via a virtual knife line or a toothed knife line. When unpacking, the opening 10 can be opened by tearing off the long strip along the virtual knife line or the toothed knife line.

[0057] In addition, the tear strip can also be a plastic tear tape, which is arranged at the internal position of the part to be separated 34. The plastic tear tape can tear off the carton at the part to be separated 34 under the action of external force, so that the box cover 3 is separated from the part to be separated 34, thereby opening the opening 10.

[0058] Thus, the box can be opened by hand without using tools, and damage to the box body 1 can be reduced.

[0059] It should be noted that the separation portion 34 can also be a separation plate, and specifically, the folding plate 32 itself can be formed as a separation plate. Specifically, the folding plate 32 and the main board 31 are integrally formed, and the folding plate 32 and the main board 31 are connected by a virtual knife line or a serrated knife line. When unpacking, the folding plate 32 is torn off as a whole along the virtual knife line or the serrated knife line, so that the main board 31 and the folding plate 32 can be separated, thereby releasing the connection between the main board 31 and the box body 1, and the main board 31 can be rotated relative to the box body 1 to open the opening 10.

[0060] Further, see Figure 4 Along the length direction of the tear strip, at least one end of the tear strip is provided with a pull-out structure 341.

[0061] Specifically, the pull-out structure 341 can be a tear-off plate segment or a tear-off strip segment, which is arranged on the box cover 3 or protrudes from the edge of the box cover 3. The pull-out structure 341 is connected to the main body segment of the tear strip, and the width of the pull-out structure 341 is greater than the width of the main body segment, so that a person can grasp the pull-out structure 341 and tear off the main body segment with force, thereby realizing tool-free box opening.

[0062] Further, see Figure 3 and Figure 4 The box body 1 includes a bottom plate 12, a front side plate 13 and a rear side plate 15 arranged opposite to each other, a left end plate 14 and a right end plate 16 arranged opposite to each other, and the front side plate 13, the left end plate 14, the rear side plate 15 and the right end plate 16 are sequentially connected to the periphery of the bottom plate 12, so that the front side plate 13, the left end plate 14, the rear side plate 15, the right end plate 16 and the bottom plate 12 are collectively enclosed to form a receiving space. Among them, one side of the main plate 31 is rotatably connected to the upper end of the rear side plate 15, and the folding plate 32 is used to fit with the front side plate 13 when the box cover 3 covers the opening 10.

[0063] On the basis of this structure, the panels of the box body 1 and the box cover 3 are integrally formed. Specifically, a whole plate is cut and creased so that the whole plate is divided into different panels by the creases, and different panels can be folded into the box body 1 through the creases.

[0064] Therefore, the panels of the box body 1 and the box cover 3 are manufactured by integral molding, which can save sheet materials, and the components are connected by folding, reducing or eliminating the use of glue, tape, etc., which can save resources and protect the environment.

[0065] Furthermore, the upper end of the front side plate 13 is rotatably connected to a connecting plate 18 , and a side of the connecting plate 18 away from the front side plate 13 is connected to the buffer assembly 2 .

[0066] Among them, compared with manufacturing the buffer component 2 and the box body 1 separately and then assembling them, the buffer component 2 in the present application is integrally formed with the box body 1, which can save materials; the buffer component 2 is rotatably connected to the box body 1 through the connecting plate 18, and the buffer component 2 can be installed into the box body 1 during the rotation process to achieve assembly, or it can be placed outside the box body 1, saving assembly time and ready for use.

[0067] In addition, the buffer assembly 2 can also be connected to the left end plate 14 or the right end plate 16 of the box body 1 through the connecting plate 18 .

[0068] Furthermore, the upper ends of the left end plate 14 and the right end plate 16 are both rotatably connected with the vertical plate 17, and the vertical plate 17 is provided with a connecting tongue 171 protruding outward at one end away from the left end plate 14 or the right end plate 16. Correspondingly, the bottom plate 12 is provided with a connecting groove 121. The connecting tongue 171 is used to be plugged and matched with the connecting groove 121 when the vertical plate 17 is rotated to fit with the left end plate 14 or the right end plate 16.

[0069] Based on this structure, the left end plate 14 and the right end plate 16 are connected to the vertical plate 17 through folds, so that the vertical plate 17 can rotate around the folds. Figure 4 , the vertical plate 17 can be in the same plane with the left end plate 14 and the right end plate 16 after rotation, and the packaging box is in an unfolded cardboard state that is convenient for transportation; when the unfolded cardboard is folded into a packaging box, refer to Figure 3 , the left end plate 14 and the right end plate 16 are rotated to be perpendicular to the bottom plate 12 of the box body 1, and then the vertical plate 17 is rotated 180° around the fold, so that the end of the vertical plate 17 with the connecting tongue 171 is facing the bottom plate 12, so that the connecting tongue 171 can be inserted into the connecting groove 121.

[0070] Therefore, through the limiting connection between the vertical plate 17 and the bottom plate 12, the vertical plate 17 can be vertically installed on the inner side of the left end plate 14 and the right end plate 16. The vertical plate 17 can support the left end plate 14 and the right end plate 16, thereby enhancing the strength of the side of the box body 1.

[0071] In addition, the connecting groove 121 on the bottom plate 12 can be set at the edge of the bottom plate 12, so that after the vertical plate 17 is connected to the bottom plate 12, the left end plate 14 and the right end plate 16 are both in contact with the vertical plate 17, which can reduce the space occupied by the vertical plate 17 and ensure the capacity of the internal accommodating space of the box body 1.

[0072] Further, see Figure 1 The buffer assembly 2 includes four support plates 22, the pad 21 is in a square shape, and the four support plates 22 are connected to the four sides of the pad 21. Specifically, the support plate 22 includes a support plate segment 221 and a clamping plate segment 222, the support plate segment 221 is rotatably connected to the pad 21, and the clamping plate segment 222 is arranged above the middle of the support plate segment 221. The clamping plate segments 222 on the four support plates 22 are arranged to form a limiting groove, and the two clamping plate segments 222 arranged opposite to each other are used to approach or move away from each other during the rotation process, so that the size of the limiting groove can be adjusted.

[0073] Based on this structure, when packaging products, the support plate segment 221 can be adjusted to rotate downward relative to the pad 21, and the clamping plate segment 222 can rotate upward under the drive of the support plate segment 221, so that the two clamping plate segments 222 arranged opposite to each other are moved away from each other, so as to adjust the size of the limiting groove to be larger. Then, the product is placed in the limiting groove, and the pad 21 is depressed downward under the pressure of the product's gravity, while the support plate segment 221 rotates upward relative to the pad 21 to the side of the pad 21 under the pressure of the pad 21, and the clamping plate segment 222 rotates downward and approaches the product under the drive of the support plate segment 221, so as to automatically clamp the product.

[0074] When the support plate segment 221 rotates upward relative to the backing plate 21 to the side of the backing plate 21, the support plate segment 221 is pressed against the side wall of the box body 1, thereby supporting the clamping plate segment 222 to clamp the product. In addition, the gravity of the product acts on the clamping plate segment 222, and the clamping plate segment 222 supports the product obliquely upward. The inner walls of the box body 1 provide support force to the clamping plate segment 222 through the support plate segment 221, so that the four clamping plate segments 222 can clamp the product.

[0075] In this way, the product can be pressed down under its own weight, and at the same time drive the two relatively arranged clamping plate segments 222 to approach each other until they abut against the sides of the product, thereby automatically clamping the product in the limiting groove. The four clamping plate segments 222 can limit the product from the sides of the product to ensure that the product does not swing back and forth or left and right during transportation. As a result, the clamping plate segments 222 can hold the product in the air to prevent the product from directly contacting the inner wall of the box 1, thereby reducing the collision force on the product during transportation.

[0076] It should be noted that the pad 21 is also provided with receiving grooves 211 around its edges, and the receiving grooves 211 are used to receive the clamping plate sections 222 when the packaging box is in an unfolded cardboard state, so that the unfolded cardboard of the packaging box can be laid flat for easy transportation.

[0077] In addition, the pad 21 may also be circular in shape, and correspondingly, two or three support plates 22 may be provided, and the plurality of support plates 22 are provided around the circumference of the pad 21. The cross-sectional shape of the clamping plate segment 222 facing the product is adapted to the peripheral shape of the product, so that when the clamping plate segment 222 clamps the product, the connection area between the clamping plate segment 222 and the product is increased, thereby ensuring the clamping effect.

[0078] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
