Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a cake box that can be resealed. Background Technology

[0002] Cakes are mostly made of soft materials, so during transportation, they need to be placed on a cake plate first, and then the cake plate is placed in a cake box for transport. The main purpose of the cake box is to prevent the cake from coming into contact with the outside world during transportation, thus maintaining the cake's shape. Due to changes in purchasing methods, cake sales have shifted from offline self-pickup to online logistics. Online logistics involves merchants packaging cakes in cake boxes and handing them over to a transportation company for transport, with delivery and acceptance at a designated location. Online logistics requires that once the cake box is opened, it cannot be restored to its original packaging form to ensure food safety during transportation. In addition, to adapt to the long-distance and even stacked transportation environment of online logistics, cake boxes are mostly made of cardboard and do not have transparent parts, thus meeting the strength and cost requirements of the cake box. To meet these requirements, existing cake boxes often use a resealable structure combined with additional seals, but this inevitably results in accessories other than the cake box itself. If a cake box that cannot be restored after opening is used alone, it becomes difficult for the buyer to store or transport the cake after acceptance and opening. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a cake box that can be resealed, which meets the requirement that the original packaging form cannot be restored after opening, and can be resealed after opening; at the same time, this technical solution is easy to disassemble and assemble, and does not easily generate additional vibration, so as to ensure the integrity of the cake shape; it can also meet the requirement of packaging and transporting cakes and related accessories at the same time.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0005] A resealable cake box includes a box body with a first opening. A first outer cover and a second outer cover are rotatably connected to the first opening. The first outer cover has a first insertion hole, and the second outer cover has a first insertion block that mates with the first insertion hole. The box also includes an adhesive component, which is disposed between the first and second outer cover and fixes the first and second outer cover together.

[0006] This technical solution is achieved by adhesive (such as glue) during the initial packaging. When it is opened for acceptance, it needs to be done by destroying the structure of the outer cover or the fixed connection between the first outer cover and the second outer cover, so the original packaging form cannot be restored. During the secondary packaging, it is achieved by the matching first insertion hole and first insertion block.

[0007] Furthermore, the first socket is located near the rotating end of the first outer cover, and the adhesive part engages with the free end of the first outer cover; a break strip is also provided on the first outer cover, and the break strip is located between the first socket and the free end of the first outer cover.

[0008] To ensure the sealing strength of the cake box during the initial sealing, the adhesive parts are mostly made of materials with high adhesive strength, thus ensuring that the first and second outer covers are not easily separated. By setting a disconnect strip, the rotating end of the first outer cover and the free end of the fixed first outer cover are disconnected, allowing the rotating end of the first outer cover to rotate freely, while the original free end of the first outer cover is still fixed to the second outer cover, thereby reducing the vibration that may be generated when opening. At the same time, the first insertion hole is retained on the rotating end side of the first outer cover, so that secondary sealing can still be achieved.

[0009] Furthermore, the disconnect strip includes a starting part and a connecting part. The starting part is located at one end of the disconnect strip and is connected to the connecting part. The two sides of the starting part are disconnected from the first outer cover piece. The connecting part is point-connected or intermittently connected to the first outer cover piece.

[0010] Since the starting part is not fixed on both sides, the user can easily pull the starting part outward in a direction perpendicular to the first outer cover to disconnect the point connection or intermittent connection on both sides of the first outer cover, making it easy to open and reducing vibration.

[0011] Preferably, the number of connecting parts is at least two, and the starting part and the connecting parts are rotatably connected as well as adjacent connecting parts.

[0012] The rotating connection between the starting part and the connecting part, as well as between adjacent connecting parts, ensures that the starting part and the disconnected connecting parts are not affected by the connecting parts that are still connected. The disconnect strip can be pulled open more easily, thus making it easier to open and reducing vibration.

[0013] Furthermore, the first insert is rotatably connected to the free end of the second outer cover.

[0014] During the initial packaging, the first insert and the second outer cover are on the same plane. During the secondary packaging, the first insert is rotated to mate with the first socket, which does not occupy extra space and is easy to operate when connected to the free end of the second outer cover.

[0015] Preferably, the first plug is composed of a first plug and a first tail, with the free ends of the first plug, the first tail, and the second outer cover connected in sequence. The width of the first plug gradually increases from the free end of the first plug towards the first tail. The minimum width of the first plug is less than or equal to and the maximum width is greater than or equal to the width of the first socket. The width of the first tail is less than or equal to the width of the first socket.

[0016] The structure of the first plug and the first tail allows the first plug to pass completely through the first socket and be confined inside the first socket, making it difficult for it to move.

[0017] Furthermore, the first outer cover and the second outer cover are disposed on opposite sides of the first opening, and an inner cover is rotatably connected to the first opening. The inner cover includes a bent portion, an extension portion, and a partition portion. The first opening, the bent portion, the extension portion, and the partition portion are rotatably connected in sequence. The bent portion contacts and engages with the first outer cover and / or the second outer cover. The extension portion is disposed toward the inner side of the box, and the partition portion divides the space inside the box.

[0018] The inner lid not only provides sealing but also divides the space inside the box, allowing the cake and related accessories to be placed in the same cake box without affecting each other.

[0019] Preferably, the inner cover includes a first inner cover and a second inner cover, which are disposed on opposite sides of the first opening. The spacer portion of the first inner cover and the spacer portion of the second inner cover cooperate to divide the internal space of the box into two parts.

[0020] The first and second inner cover sheets, which are positioned opposite each other, can be sealed by pressing the extension part into the box with both hands, making the operation more convenient.

[0021] Preferably, the separating portion is provided with an opening or a slot.

[0022] The openings or slots make it easier to open the partition.

[0023] Preferably, the box body is further provided with a second opening, which is disposed opposite to the first opening. The second opening is rotatably connected to a third outer cover and a fourth outer cover. The third outer cover is provided with a second insertion hole. The free end of the fourth outer cover is rotatably connected to a second plug that mates with the second insertion hole. The second plug consists of a second plug and a second plug tail. The second plug includes a main body and a side wing. One side of the main body is connected to the second plug tail, and at least one side intersecting with it is rotatably connected to the side wing. The width of the main body and the second plug tail is less than or equal to the width of the first insertion hole. The sum of the widths of the main body and the side wing after unfolding is greater than the width of the first insertion hole. The sum of the thicknesses of the main body and the side wing after folding is less than or equal to the height of the first insertion hole.

[0024] The second opening is designed to be sealed from the outside. The structure of the second plug allows the second plug to fully enter the second socket. After entering, the side wings will spring out without external force, thus locking onto the inner wall of the third outer cover to prevent the second plug from being pulled out of the second socket. After the cake is taken out of the cake box, the user can operate the side wings from the inside of the cake box to remove the second plug from the second socket, thus folding the cake box for storage. When needed, the cake box can be reassembled to be sealed through the first socket and the first plug, and the second socket and the second plug.

[0026] 1. It meets the requirement that the cake box cannot be restored to its original packaging form after being opened, and it can be resealed after being opened;

[0027] 2. The split strip structure makes it easy to open the cake box after the initial sealing, and it is less likely to cause additional vibration, so as to ensure the cake's shape remains intact;

[0028] 3. The structure of the first insert block ensures that the cake box after secondary sealing is both reliably positioned and easy to open again;

[0029] 4. The inner lid structure divides the internal space of the box into two parts, which can meet the requirements of packaging and transporting cakes and related accessories at the same time, and is convenient to operate;

[0050] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0051] The resealable cake box in this embodiment is made of corrugated cardboard, which is lightweight and strong, making it suitable for online logistics applications. The rotational connection between different parts is achieved through preset creases. In other embodiments, it can also be made of resin, metal or other materials suitable for transport packaging.

[0052] The shape of the box in this technical solution is not limited, such as a prism with a triangular, polygonal, or circular cross-section, or a tetrahedron or frustum of a cone, etc. In this embodiment, box 1 is a cuboid, such as... Figure 1 As shown, a first opening 11 and a second opening 12 are provided on opposite sides of the box 1, allowing external items to enter the box 1 through either the first opening 11 or the second opening 12. (Combined with...) Figure 8 The upper side of the first opening 11 is rotatably connected to a first outer cover piece 2, and the lower side is rotatably connected to a second outer cover piece 3. The left and right sides are respectively rotatably connected to a first inner cover piece 4 and a second inner cover piece 5. The upper side of the second opening 12 is rotatably connected to a fourth outer cover piece 7 (not shown in the figure), and the lower side is rotatably connected to a third outer cover piece 6. The left and right sides are respectively rotatably connected to a third inner cover piece 8 and a fourth inner cover piece 9. Combined Figures 3 to 5 The upper side of the first outer cover 2 is a rotating end connected to the first opening 11, and a fixing piece 22 connected by a disconnecting strip 23 is provided below it. The two sides of the disconnecting strip 23 are connected to the first outer cover 2 at multiple connection points 233. In some embodiments, the disconnecting strip 23 can also be connected to the first outer cover 2 intermittently by using spaced edges as connecting edges. A first insertion hole 21 is provided between the rotating end and the disconnecting strip 23, so that even after the disconnecting strip 23 is disconnected, the first insertion hole 21 can still be located on one side of the rotating end. The lower side of the second outer cover 3 is a rotating end connected to the first opening 11, and a first insert block 31 is rotatably connected above it. The position of the second outer cover 3 near the rotating end is the adhesive area 32. The adhesive area 32 is fixedly connected to the fixing piece 22 to achieve initial sealing. Figure 1The image shows the initial packaging state. The first outer cover 2 is located outside the second outer cover 3. Adhesive materials (such as adhesive, double-sided tape, etc.) are used on the outer side of the adhesive area 32 or the inner side of the fixing piece 22 to fix the adhesive area 32 and the fixing piece 22 together. These adhesive materials can be disposable or have high adhesive strength so that forced separation after bonding would cause structural damage. Because the adhesive materials make the first outer cover 2 and the second outer cover 3 relatively firmly connected, the first outer cover 2 and the second outer cover 3 are released by the disconnecting strip 23, that is, the connection between the rotating end of the first outer cover 2 and the fixing piece 22 is broken, allowing the rotating end to rotate freely. The disconnecting strip 23 includes a starting part 231 and multiple connecting parts 232. The starting part 231 is located at both ends of the disconnecting strip 23, and neither side of the starting part 231 is connected to the first outer cover 2. The connecting parts 232 are connected sequentially. The starting part 231 and the connecting parts 232, as well as the adjacent connecting parts 232, are rotatably connected. The rotation direction is such that the disconnecting strip 23 moves away from the box body 1. The connection point 233 is located in the rotatably connected part. When the user pulls the starting part 231 outward, the connection point 233 on the connecting part 232 near the starting part 231 is disconnected under the action of the pulling force. Because of the rotatable connection, the disconnected connecting part 232 can also be easily pulled up, thereby driving the subsequent connecting parts 232 to disconnect the connection at the connection point 233. When the connection between all connecting parts 232 and the first outer cover 2 is disconnected, the rotating end and the fixing piece 22 are separated. At the same time, because the disconnecting strip 23 is disconnected and the fixing piece 22 is retained on the second outer cover 3, the box body 1 cannot be restored to the initial sealed state after the initial sealing is opened.

[0053] Combination Figure 2When secondary encapsulation is required, the second outer cover 3 is placed outside the first outer cover 2, and the first insert 31 is inserted into the first socket 21. The first socket 21 has a width L1 and a height H1. The first insert 31 consists of a first plug 311 and a first tail 312. The first tail 312 is rotatably connected to the second outer cover 3. The first plug 311 is approximately trapezoidal, with the side connected to the first tail 312 being the long side and the opposite side being the short side. The short side has a width L2, and the long side has a width L3. The width of the first tail 312 is the same as the width L2 of the short side. Preferably, L2 is slightly smaller than L1, such as within 2 mm. Alternatively, L1 = L2 or a smaller L2 can be used. Preferably, L3 is slightly smaller than L1. For sizes greater than L1, such as within 2mm, L1=L3 or a larger L3 can be used. Since the corrugated cardboard in this embodiment has a certain degree of elasticity, the structure of the first plug 311, which is narrow at the front and wide at the back, allows the first plug 311 to be smoothly and completely inserted into the first socket 21. Without external pulling force, the long side of the first plug 311 cooperates with the inner side of the first outer cover 2 to prevent the first plug block 31 from exiting. The first plug tail 312 cooperates with the first socket 21 to perform horizontal limiting. When external pulling force is applied to the second outer cover 3, the second outer cover 3 drives the first plug block 31. Under the action of elasticity, the first plug block 31 can also be smoothly exited from the first socket 21, realizing the release of the secondary packaging.

[0054] Combination Figure 6 and 7The second opening 12 is encapsulated by the third outer cover 6 and the fourth outer cover 7. The encapsulation of the second opening 12 is designed to be released only from inside the box 1, and cannot be released from outside the box 1 like the first opening 11. The third outer cover 6 has a second insertion hole 61 with the same size as the first insertion hole 21. The free end of the fourth outer cover 7 is rotatably connected to the second insertion block 71. The second insertion block 71 consists of a main body 711, side wings 712, and a second insertion tail 713. The second insertion tail 713 is rotatably connected to the fourth outer cover 7 and one side of the main body 711. The two adjacent sides of the main body 711 are connected to the side wings 712. The side wings 712 are rotatably connected to the main body 711. When the side wings 712 are folded, the main body 711 alone has a width L4. When the side wings 712 are unfolded, the main body 711 plus the two side wings 712 have a width L5. Preferably, L1 = L 4. Alternatively, a smaller L4 can be selected, preferably L5 is greater than L1 by more than 10mm. The width of the second insertion tail 713 is the same as the width of the first insertion tail 312. When the second insertion block 71 needs to enter the second insertion hole 61, by folding the side wing 712 onto the main body 711, the width L1 and height H1 of the second insertion hole 61 allow it to pass through. After passing through the second insertion hole 61, the side wing 712 returns to the unfolded or semi-unfolded state under the action of elasticity or gravity. Then, mainly by the cooperation of the side wing 712 with the inner side of the third outer cover 6, the second insertion block 71 is prevented from exiting. The second insertion tail 713 cooperates with the second insertion hole 61 to perform horizontal limiting. Since the length of the side wing 712 exceeds its deformation range, pulling the fourth outer cover 7 from the outside cannot make the second insertion block 71 exit. Only when the user refolds the side wing 712 from the inside of the box 1 can the encapsulation of the second opening 12 be released.

[0055] Figure 8 Used to display the internal structure of box 1 Figure 8 The first outer cover 2 (not shown in the figure), the second outer cover 3, the third outer cover 6, and the fourth outer cover 7 (not shown in the figure) are in the unfolded state, while the first inner cover 4, the second inner cover 5, the third inner cover 8, and the fourth inner cover 9 are in the folded state. The third inner cover 8 and the fourth inner cover 9 are used in conjunction with the third outer cover 6 and the fourth outer cover 7 to encapsulate the second opening 12. Figure 9 The first inner cover 4 and the second inner cover 5 have basically the same structure, both consisting of bent portions 41 and 51, extension portions 42 and 52, and separating portions 43 and 53. The difference is that the second inner cover 5 is additionally provided with a slot 54. The shape of the slot 54 facilitates operation by the user's fingers. In other embodiments, the slot 54 can also be replaced by an opening. Since the first inner cover 4 and the second inner cover 5 have basically the same structure and are basically symmetrically arranged on opposite sides of the first opening 11, only the structure and arrangement of the second inner cover 5 are described here. Those skilled in the art can refer to the description in conjunction with... Figure 8 and9 The structure and arrangement of the first inner cover 4 are obtained. The second inner cover 5 includes a bent portion 51, an extension portion 52, and a partition portion 53. The two sides of the bent portion 51 are rotatably connected to the first opening 11 and the extension portion 52, respectively. The other side of the extension portion 52 is rotatably connected to the partition portion 53. The bent portion 51 has a short width to help the extension portion 52 rotate and enter the box body 1. It is also used to cooperate with the first outer cover 2 and / or the second outer cover 3 to close the left and right sides of the first opening 11. The extension portion 52 extends into the box body 1, and the extension distance is adapted to the size of the space to be divided. The partition portion 53 is arranged horizontally. By cooperating with the partition portion 43 of the first inner cover, the box body 1 is divided into a first space 13 and a second space 14. The first space 13 is used to place cake plates and cakes, and the second space 14 is used to place related accessories. With the cooperation of the partition portions 43 and 53, the items in the first space 13 and the second space 14 will not affect each other.
