Description

Technical Field

[0001] This application relates to the field of food packaging box technology, and in particular to an anti-theft food packaging box. Background Technology

[0002] With the rapid development of the food industry and the increasing awareness of food safety among consumers, food packaging technology is also constantly innovating and improving. Traditional food packaging boxes typically use a simple lid-and-box structure, allowing consumers to easily open the packaging and access the food. However, in certain special application scenarios, such as packaging for high-value foods, pharmaceuticals, health products, or foods requiring controlled access, traditional packaging structures have significant shortcomings. Traditional packaging boxes often use a simple nesting or snap-fit ​​connection between the lid and the box body, leaving the lid edge completely exposed. Anyone can easily lift the lid, failing to provide effective anti-theft or anti-accidental opening functions. Utility Model Content

[0003] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide an anti-theft food packaging box with a lid that is difficult to open, thus offering higher anti-theft performance.

[0004] An anti-theft food packaging box, comprising: The box body has a first annular step and a second annular step arranged around the inside of the opening side of the box body. The first annular step is located below the second annular step and the first annular step and the second annular step are connected in sequence. From the inside to the outside of the box body, there are a first step surface, a second step surface and a third step surface. The diameters of the first step surface, the second step surface and the third step surface increase in sequence. A break line is provided on the second annular step, which extends from the edge of the second step surface to the third step surface. The area enclosed by the break line is a detachable structure. The lid has a raised edge on its edge. After the lid is assembled onto the box body, the raised edge is mounted on the first annular step, and the edge of the lid is located below the third step surface.

[0005] In an optional or preferred embodiment, the edge of the lid is provided with a flange for fitting against the second step surface.

[0006] In an optional or preferred embodiment, the width of the flange is less than or equal to the width of the second step surface.

[0007] In an optional or preferred embodiment, the lid is provided with a vent hole, and a baffle is provided in the vent hole.

[0008] In an optional or preferred embodiment, the surface of the detachable structure is provided with a first friction texture.

[0009] In an optional or preferred embodiment, the flange is provided with a second friction pattern on one side of the second step surface.

[0010] In an optional or preferred embodiment, a groove is provided at the corner of the second annular step, and the edge of the flange is embedded in the groove.

[0011] In an optional or preferred embodiment, the top of the box is a circular structure and the bottom is a square structure.

[0012] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: When a consumer opens the box lid for the first time, they need to tear open the detachable structure along the fracture line. This creates a notch in the box, which the consumer must insert their hand to remove the lid. The fracture line and detachable structure ensure the uniqueness and irreversibility of the first opening. Once opened, the detachable structure will not revert, effectively preventing the packaging from being opened by others beforehand, providing a significant anti-theft effect. The edge of the lid is completely hidden below the third step surface. This structure avoids the situation where the edge of the lid is exposed and easily pried open, increasing the difficulty of opening and improving anti-theft performance. Attached Figure Description

[0021] With the rapid development of the food industry and the increasing awareness of food safety among consumers, food packaging technology is also constantly innovating and improving. Traditional food packaging boxes usually adopt a simple lid-and-box structure, allowing consumers to easily open the packaging and access the food. However, in certain special application scenarios, such as packaging for high-value foods, pharmaceuticals, health products, or foods requiring controlled access, traditional packaging structures have significant shortcomings.

[0022] Traditional packaging boxes typically use a simple nesting or snap-fit ​​connection between the lid and the box body, with the edge of the lid completely exposed. Anyone can easily open the lid, which cannot provide effective anti-theft or anti-accidental opening functions. Although there are some packaging options on the market with security seals or plastic film coverings, these solutions usually require additional materials and processes, increasing packaging costs.

[0023] Reference Figures 1 to 4 This application provides an anti-theft food packaging box, including a box body 100 and a box lid 200.

[0024] The opening side of the box 100 is surrounded by a first annular step 110 and a second annular step 120. The first annular step 110 is located below the second annular step 120, and the first annular step 110 and the second annular step 120 are connected in sequence. From the inside to the outside of the box 100, there are three steps: a first step surface 130, a second step surface 140, and a third step surface 150, and the diameters of the three increase sequentially.

[0025] A fracture line 160 is provided at the upper end of the second annular step 120. The fracture line 160 extends from the edge of the second step surface 140 to the edge of the third step surface 150, and the area enclosed by the fracture line 160 is the detachable structure 170. When a consumer opens the box lid 200 for the first time, they need to tear open the detachable structure 170 along the fracture line 160. At this time, a notch will be formed on the box body 100, and the consumer can reach into the notch to remove the box lid 200. The fracture line 160 and the detachable structure 170 ensure the uniqueness and irreversibility of the first opening. Once opened, the detachable structure 170 will not be restored, which can effectively prevent the packaging from being opened by others in advance, and has a significant anti-theft effect. In order to facilitate users to quickly identify the detachable structure 170, in some embodiments, the surface of the detachable structure 170 is provided with a first friction texture 171.

[0026] Specifically, the fracture line 160 is a structure made up of rectangular through holes spliced ​​together at intervals. During use, an opening can be quickly torn out on the box 100 along the fracture line 160.

[0027] The lid 200 has a raised edge 210 around its edge. When the lid 200 is assembled onto the box body 100, the raised edge 210 is embedded in the first annular step 110. Simultaneously, the edge of the lid 200 is located below the third step surface 150. This structure conceals the edge of the lid 200 below the third step surface 150, preventing the edge of the lid 200 from being easily pried open, increasing the difficulty of opening and improving anti-theft performance.

[0028] In some embodiments, a flange 220 is provided around the edge of the lid 200, which is attached to the second stepped surface 140. The flange 220 allows the user to easily remove the detachable structure 170 and then grasp the flange 220 to open the lid 200. Simultaneously, because the flange 220 is attached to the second stepped surface 140, the sealing performance between the edge of the lid 200 and the edge of the box body 100 is improved.

[0029] In some embodiments, the flange 220 is provided with a second friction texture on one side of the second step surface 140. Thus, when the user removes the detachable structure 170 and grasps the flange 220 through the notch, the second friction texture increases the friction between the finger and the flange 220, resulting in better anti-slip performance.

[0030] Furthermore, the width of the flange 220 is equal to the width of the second step surface 140. This way, after the lid 200 is placed on the box body 100, the flange 220 covers the second step surface 140, reducing the stress points on the flange 220 and further preventing the lid 200 from being easily pried open. Of course, in other embodiments, the width of the flange 220 can also be set to be less than the width of the second step surface 140.

[0031] In some embodiments, the lid 200 has a vent hole, and a baffle 230 is installed in the vent hole. When the food needs to be vented or kept ventilated, the consumer presses the baffle 230 to open the vent hole. In addition, during the process of opening the lid 200, the baffle 230 can be pressed down and the consumer can put their hand into the vent hole to open the lid 200.

[0032] Specifically, the ventilation holes on the lid 200 are directly cut out, and the baffle 230 is also part of the lid 200.

[0033] In some embodiments, a groove is provided at the corner of the second annular step 120, and the edge of the flange 220 is embedded in the groove.

[0034] Specifically, the corner of the second annular step 120 is the corner between the second step surface 140 and the step elevation of the second annular step 120. After the lid 200 is assembled onto the box body 100, the edge of the flange 220 is embedded in the groove, thus concealing the edge of the flange 220. This prevents the flange 220 from being pried open from the second annular step 120, further improving the anti-theft performance. Furthermore, when the entire box body 100 is subjected to lateral compressive force, the flange 220, being concealed in the groove, restricts its movement. This effectively prevents the box body 100 from being deformed by compression, causing the lid 200 to detach, thus effectively improving the lateral compression resistance of the packaging box of this application.

[0035] The box 100 in this application has a circular top and a square bottom, forming a shape resembling a round heaven and a square earth.

[0036] Therefore, this anti-theft food packaging box can effectively solve the problems of traditional packaging structures being easily opened and having poor anti-theft performance in the background technology, and also has outstanding practical value in food preservation and transportation.

[0037] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application 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 this application.
