Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food packaging, and specifically relates to a packaging box with a disposable anti-theft buckle. Background Art
[0002] The main function of a disposable anti-theft buckle packaging box is to prevent the goods from being unauthorizedly opened or replaced during transportation or sales. This kind of packaging box usually has a special design. Once it is opened, the relevant anti-theft mechanism will fail, thus reminding consumers that the packaging may have been tampered with. The packaging box with a disposable anti-theft buckle is mainly used in takeaways. Consumers can judge whether the packaging has been opened by checking the integrity of the anti-theft buckle, ensuring that the delivery staff has not stolen or added items to the contents inside the packaging box. However, the disposable packaging box is made of plastic and has flexibility. When the anti-theft buckle is thin and in the form of a buckle lock pressing, the lid of the packaging box can deform softly under its flexibility, and then the lid is easily separated from the position pressed by the anti-theft buckle and loosened, resulting in poor anti-theft effect. Summary of the Utility Model
[0003] The utility model provides a packaging box with a disposable anti-theft buckle, which overcomes the deficiencies described in the background art.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] A packaging box with a disposable anti-theft buckle includes a cover plate, a protruding block, and a containing box. The protruding block is arranged on the upper surface of the cover plate, and the cover plate coincides with the upper edge of the protruding block. When the protruding block is screwed, the containing box is fixed, driving the protruding block to rotate and loosen the connection with the containing box.
[0006] The cover plate includes a connecting ring, a plastic plate, a transparent cover, an anti-theft block, and a sealing plate. The sealing plate protrudes from the surface of the connecting ring and abuts against the lower end of the transparent cover. The connecting ring is arranged outside the containing box and protrudes outwards. Two anti-theft blocks are respectively arranged on the outside of the transparent cover and the connecting ring, and the two anti-theft blocks are connected up and down by a plastic plate. And the four anti-theft blocks are provided with two groups, symmetrically arranged at the left and right ends of the transparent cover. When the transparent cover rotates, since the connecting ring is connected and fixed to the side surface of the containing box, the lower surface of the transparent cover is in sliding fit with the connecting ring, and the transparent cover drives the upper anti-theft block to form a torsion force on the lower anti-theft block to tear the plastic plate.
[0007] A preferred technical solution: The transparent cover includes a rotating mark adhered to the surface of the cover body, and there are two rotating marks distributed around the protruding block.
[0008] A preferred technical solution: The protruding block is located on the upper surface in the middle of the transparent cover, and the protruding block is in the shape of an inverted "convex" with a wide upper end and a narrow lower end.
[0009] A preferred technical solution: the plastic plate is formed by a plurality of thin plastic strips arranged and distributed, and the plastic plates are arranged at one quarter of the outer side of the anti-theft block.
[0010] A better technical solution: the sealing plate includes a sliding bar and a stress bar, and the sliding bar is in a triangular shape, the contact area between the top of the sliding bar and the bottom surface of the transparent cover is small, and the stress bar is made of sponge material, and the stress bar is against and slides against the lower surface of the transparent cover.
[0011] Compared with the prior art, this technical solution has the following advantages:
[0012] After the containing box is fixed in the utility model, the protruding block is manually rotated to drive the cover body in the transparent cover to rotate on the sealing plate on the surface of the connecting ring, so that the cover body and the connecting ring form a reverse rotation, so that the two anti-theft blocks are twisted in the direction of the connecting ring and the transparent cover, and the plastic plate between the two anti-theft blocks is disconnected due to the rotational torque. After the two anti-theft blocks are disconnected, they are no longer complete, so opening and closing the transparent cover and the containing box will destroy the integrity of the plastic plate, thereby achieving a better anti-theft effect.
[0013] When the transparent cover in the utility model rotates, the bottom plane of the cover body rotates and slides on the top of the sliding strip, thereby reducing the friction resistance of rotation, and the force strip is pressed and compressed by the bottom of the cover body, so that when the inside of the protruding block is covered by the transparent cover, the connection is compressed and sealed by the force strip, thereby enhancing the sealing performance of the food inside the protruding block.

[0020] like Figures 1 to 4As shown, the utility model proposes a packaging box with a disposable anti-theft buckle, comprising a cover plate 1, a protruding block 2, and a containing box 3. The protruding block 2 is arranged on the upper surface of the cover plate 1, and the cover plate 1 is matched with the upper edge of the protruding block 2. When the protruding block 2 is screwed, the containing box 3 is fixed, and the protruding block 2 is driven to rotate and loosen the connection with the containing box 3;
[0021] The covering plate 1 includes a connecting ring 11, a plastic plate 12, a transparent cover 13, an anti-theft block 14, and a sealing plate 15. The sealing plate 15 protrudes from the surface of the connecting ring 11 and abuts against the lower end of the transparent cover 13. The connecting ring 11 is arranged on the outside of the containing box 3 and protrudes outward. Two anti-theft blocks 14 are respectively arranged on the outside of the transparent cover 13 and the connecting ring 11, and the two anti-theft blocks 14 are connected up and down by the plastic plate 12. There are two groups of four anti-theft blocks 14, which are symmetrically arranged at the left and right ends of the transparent cover 13. When the transparent cover 13 rotates, since the connecting ring 11 is connected and fixed to the side of the containing box 3, the lower surface of the transparent cover 13 slides with the connecting ring 11, and the transparent cover 13 drives the upper anti-theft block 14 to form a torsional tear on the lower anti-theft block 14. The plastic plate 12 is torn.
[0022] The transparent cover 13 includes a rotation mark 131 bonded to the surface of the cover body 132, and the rotation mark 131 is provided with two surrounding protrusion blocks 2, and the rotation mark 131 has the effect of indicating the rotation of the protrusion block 2, and the twisting effect can be achieved by rotating clockwise or counterclockwise.
[0023] The protruding block 2 is located on the upper middle surface of the transparent cover 13, and the protruding block 2 is in a reverse "convex" shape with a wide upper end and a narrow lower end. The protruding position is convenient for finger operation and rotation.
[0024] Among them, the plastic plate 12 is formed by a plurality of thin plastic strips arranged and distributed, and the plastic plate 12 is arranged and arranged at one quarter of the outer side of the anti-theft block 14, and the position where it connects to the anti-theft block 14 is small, so that the rotational torque of the transparent cover 13 can easily break the plastic plate 12, preventing the plastic plate 12 from being easily broken and affecting the opening of the containing box 3.
[0025] The sealing plate 15 includes a sliding bar 151 and a stress bar 152, and the sliding bar 151 is in a triangular shape. The contact area between the top of the sliding bar 151 and the bottom surface of the transparent cover 13 is small. The stress bar 152 is made of sponge material, and the stress bar 152 is against and slides against the lower surface of the transparent cover 13.
[0026] In the present utility model, after the fixed storage box 3 is placed, the protruding block 2 is manually rotated, driving the lid body 132 in the transparent lid 13 to rotate on the sealing plate 15 on the surface of the connecting ring 11, so that a reverse rotation is formed between the lid body 132 and the connecting ring 11. As a result, the two anti-theft blocks 14 are twisted in the direction of the connecting ring 11 and the transparent lid 13, and the plastic plate 12 between the two anti-theft blocks 14 is disconnected due to the rotational torque. After the two anti-theft blocks 14 are disconnected, they are no longer complete. Therefore, opening and closing the transparent lid 13 and the storage box 3 will damage the integrity of the plastic plate 12, achieving a better anti-theft effect.
[0027] When the transparent lid 13 rotates in the present utility model, the bottom plane of the lid body 132 rotates and slides on the top of the sliding strip 151, reducing the frictional resistance of the rotation. And the force-receiving strip 152 is compressed by being pressed against the bottom of the lid body 132, so that when the inside of the protruding block 2 is covered by the transparent lid 13, the connection part is compressed and sealed by the force-receiving strip 152, enhancing the food tightness inside the protruding block 2.
[0028] It is necessary to explain that in the present utility model, rotating the protruding block 2 can twist and disconnect the connection of the plastic plate 12 between the anti-theft blocks 14 of the transparent lid 13, realizing the one-time anti-theft opening and closing of the transparent lid 13 and the storage box 3. In addition to the rotating protruding block 2, in the present utility model, the two anti-theft blocks 14 can also be directly rotated by hand. The two anti-theft blocks 14 are made of plastic and are irregularly extruded after generating rotational deformation, which can cause the plastic plate 12 between the two anti-theft blocks 14 to crack. In the present utility model, both of the two usage methods can achieve the effect of disconnecting the integrity of the anti-theft blocks 14 and opening the transparent lid 13.
[0029] The above is only a preferred embodiment of the present utility model, so the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present utility model patent and the content of the specification should still fall within the scope covered by the present utility model.
