Description

Technical Field

[0001] This utility model relates to the field of box technology, and in particular to an anti-opening packaging box. Background Technology

[0002] Currently, flip-top packaging boxes typically consist of two parts: a box body and a lid. The rear end of the lid connects to the box body, forming a flip-top structure. These boxes are widely used in food packaging, such as for restaurant delivery. However, during delivery, the boxes may be opened by unauthorized personnel, and it's difficult to visually determine if they've been opened after being resealed, posing risks of food contamination, tampering, or other safety hazards. To address this issue, a common practice is for vendors to seal the joint between the lid and box body with stickers or other adhesive materials after packaging. Once the sticker is torn off, it leaves a visible mark, allowing recipients to determine if the box has been illegally opened during delivery. However, this anti-tampering method has limitations in practical application: firstly, vendors need to perform additional sealing after packaging, increasing the complexity of the packaging process and affecting efficiency; secondly, sealing materials need to be purchased and used separately, increasing the hassle and cost of additional packaging materials.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An tamper-evident packaging box includes a lid 100 and a box body 200. The box body 200 has a receiving cavity 201 with an upper opening. One side of the lid 100 is connected to the box body 200 and can rotate and open relative to the box body 200 to cover or open the opening of the receiving cavity 201. The other side of the lid 100 is provided with an insert portion 110. The side of the box body 200 corresponding to the insert portion 110 is a front wall portion 210. The front wall portion 210 and the insert portion 110... One of the two is provided with a first tongue 220, and the other is provided with a first slot 111 for the first tongue 220 to be inserted. The side of the first tongue 220 is provided with a hook 221. When the first tongue 220 is inserted into the first slot 111, the front wall 210 and the insert 110 can be engaged through the hook 221. The side of the first slot 111 is provided with an easy-tear line 112 so that the first slot 111 can be torn open.

[0024] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, the box body 200 has an open container structure, with a accommodating cavity 201 with an upper opening in the middle. Its rear side is connected to the rear side of the cover body 100. The cover body 100 can rotate and open relative to the box body 200. The insert part 110 is provided on the front side of the cover body 100 and is used to cooperate with the front wall part 210 of the box body 200. When packaging food, the food is placed into the receiving cavity 201 of the box body 200, and then the lid 100 is flipped and closed so that the lid 100 covers the opening of the receiving cavity 201. At the same time, the insert portion 110 is flipped to be aligned with the front wall portion 210, so that the first insert tongue 220 is inserted into the first insert slot 111. The latch portion 221 of the first insert tongue 220 engages with the front wall portion 210, thereby locking the lid 100 and reducing the possibility of it being opened. When the person receiving the food opens the packaging box, they can tear open the first insert slot 111 through the easy-tear line 112 on the side of the first insert slot 111, thereby allowing the latch portion 221 of the first insert tongue 221 to engage. The lid 100 can be opened by disengaging the front wall 210 and the insert 110, allowing the receiving personnel to easily consume the food in the receiving cavity 201. If the packaging box is opened without authorization by someone other than the receiving personnel during delivery, the easy-tear line 112 on the side of the first insert 111 will tear at the first insert 111 when the hook 221 is forcibly disengaged. The receiving personnel can then determine whether the packaging box has been illegally opened during delivery by observing the tear condition of the easy-tear line 112 at the first insert 111, thus achieving an anti-opening function. This anti-opening design avoids the hassle of using stickers for sealing, simplifies the packaging process, reduces packaging material costs, and is easy to use. In practical applications, the specific structure of the box body 200 and the lid 100 can be changed according to actual usage needs.

[0025] In some embodiments, the front wall portion 210 is provided with a first notch 211, the first tongue 220 is provided at the first notch 211, and the first insertion slot 111 is provided at the middle of the insertion portion 110.

[0026] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the first tongue 220 is located at the first notch 211 of the front wall portion 210, and has hook portions 221 on both its left and right sides. The first insertion slot 111 is located in the middle of the insertion piece portion 110, and has easy-tear lines 112 on both its left and right sides. In use, the first tongue 220 is inserted into the first insertion slot 111. Due to the pressure of the insertion piece portion 110, the hook portions 221 on both sides of the first tongue 220 bend backward and engage with the lower wall of the first insertion slot 111, so that the front wall portion 210 and the insertion piece portion 110 are engaged and locked. This design allows the front wall portion 210 and the insertion piece portion 110 to achieve a good covering effect and good engagement stability. In practical applications, in addition to the above structure, the first insertion slot 111 and the easy-tear line 112 can also be set on the front wall portion 210, and the first insertion tongue 220 can be set on the insertion piece portion 110. The specific settings can be made according to the actual needs of use.

[0027] In some embodiments, the side of the first tongue 220 facing the first slot 111 has an arc-shaped structure, and the hook portion 221 has a barb-shaped structure. It is understood that, as Figure 1 and Figure 3 As shown, the upper side of the first tongue 220 has an arc-shaped structure to facilitate its insertion into the first slot 111, and the hook portion 221 has a barb-shaped structure to facilitate the hook portion 221 engaging with the lower wall of the first slot 111, thereby achieving a relatively stable engaging effect. In practical applications, the specific structures of the first tongue 220 and the hook portion 221 can be varied according to actual usage needs.

[0028] In some embodiments, the housing 200 is provided with side wings 230 on both the left and right sides of the opening of the accommodating cavity 201. It is understood that, as Figure 1 , Figure 2 and Figure 4 As shown, two side wings 230 are respectively disposed on the left and right sides of the opening of the receiving cavity 201. By providing the side wings 230, the support for the left and right sides of the lid 100 can be enhanced when the packaging box is in the closed state, while providing a better covering effect for the gaps on the left and right sides, making it convenient to use. In actual applications, the specific structure of the side wings 230 can be set according to the actual needs of use.

[0029] Furthermore, the cover 100 is provided with a second tongue portion 120 on both the left and right sides, and the side wing portion 230 is provided with a second insertion slot 231 for the second tongue portion 120 to be inserted. It is understood that, as... Figure 1 , Figure 2 and Figure 4As shown, in use, the lid body 100 is flipped to cover the box body 200, the front side thereof is locked by the engagement of the first tongue portion 220 and the first insertion slot 111, and the left and right sides thereof are engaged with the left and right sides of the box body 200 by inserting the second tongue portion 120 into the second insertion slot 231 of the side wing portion 230, which can achieve a relatively stable covering effect and is convenient for use. In practical applications, the second tongue portion 120 and the second insertion slot 231 can be set correspondingly according to actual use requirements.

[0030] Further, the left and right sides of the lid body 100 are both provided with a second notch position 101, and the second tongue portion 120 is disposed at the second notch position 101. It is understandable that, as shown in Figure 1 , Figure 2 and Figure 4 , by providing the second notch position 101 and arranging the second tongue portion 120 at the second notch position 101, the left and right sides of the lid body 100 can be substantially flush, which is beneficial for the lid to extend and cover to the left and right side edges of the box body 200, not only achieving a good shielding effect, but also obtaining good support, and is convenient for use. In practical applications, in addition to the above structure, the second tongue portion 120 may also be arranged to protrude or bend relative to the edge of the lid body 100, and the specific structure can be correspondingly changed according to actual use requirements.

[0031] Further, the second tongue portion 120 has a trapezoidal structure, and the second insertion slot 231 has a "C"-shaped structure. It is understandable that, as shown in Figure 1 , Figure 4 and Figure 5 , the second tongue portion 120 is of a trapezoidal structure to facilitate its insertion into the second insertion slot 231, and the second insertion slot 231 is of a "C"-shaped structure. When in use, the second tongue portion 120 can be pressed to push the "C"-shaped second insertion slot 231 to open, which further facilitates inserting the second tongue portion 120 into the second insertion slot 231 for convenient use. In practical applications, the specific structures of the second tongue portion 120 and the second insertion slot 231 can be correspondingly changed according to actual use requirements.

[0032] In some embodiments, an openable and closable exhaust structure is provided on the lid body 100, the box body 200, or between the lid body 100 and the box body 200. When the exhaust structure is opened, the accommodating cavity 201 can communicate with the external atmospheric environment through the exhaust structure.

[0033] It is understandable that, as shown in Figure 1 , Figure 2 and Figure 4As shown, by setting an openable and closable exhaust structure, when heat preservation is required, the exhaust structure can be closed to reduce heat loss from the container 201 and ensure a better heat preservation effect; when heat preservation is required, the exhaust structure can be opened to connect the container 201 with the external atmosphere, maintain ventilation, remove moisture from the box in time, prevent food from softening due to moisture accumulation, and make it easier to use.

[0034] Specifically, the venting structure is located at the connection between the cover 100 and the box 200 and includes two cutting slits 301. The two cutting slits 301 are spaced apart and a pressing part 310 that can be pressed and bent is formed between them. When the venting structure is opened, the pressing part 310 is bent and staggered relative to the connection between the cover 100 and the box 200, so that an vent hole 302 for venting is formed at the connection between the cover 100 and the box 200.

[0035] Understandably, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the venting structure is located at the connection between the cover 100 and the box 200 and includes two cuts 301. The cuts 301 are perpendicular to the rotational crease between the cover 100 and the box 200. The two cuts 301 are spaced apart, forming a pressable, bendable pressing part 310 between them. When the venting function is not needed, the pressing part 310 remains aligned with the connection between the cover 100 and the box 200, and the venting structure is closed. When the venting function is needed, refer to... Figure 2 Pressing the pressing part 310 causes it to bend and offset relative to the connection between the cover 100 and the box 200, forming an exhaust hole 302 for venting at the offset position. The venting structure is opened, and the accommodating cavity 201 can be connected to the external atmospheric environment through the exhaust hole 302. The above structure is simple and reasonable and easy to use.

[0036] In practical applications, in addition to the above structure, an exhaust hole 302 can also be opened on the box body 200 or the cover body 100. A detachable and tearable cover plate or a bendable and flip-up cover plate can be set at the exhaust hole 302 to cover the exhaust hole 302 and close the exhaust structure. By removing and tearing the cover plate or flipping the cover plate open, the cover plate on the exhaust hole 302 can be released, and the exhaust structure can be opened. The specific design can be changed according to the actual use needs.

[0037] In some embodiments, the cover 100 is provided with a transparent window 130. It is understood that, as Figure 5As shown, in use, a through hole can be provided in the middle of the cover 100, and a light-transmitting film or plastic plate can be placed at the through hole to form a transparent window 130, so as to facilitate observation of the food inside the packaging box and make it convenient to use. In actual application, the specific structure of the transparent window 130 can be set according to the actual use needs.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
