Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and in particular to a novel disposable, tamper-proof food packaging box. Background Technology
[0002] Food packaging boxes are commonly used for pastries, cakes, ice cream, and takeout meals. Currently, for foods like cakes, the packaging mainly consists of a base and a lid. The cake is placed on the base, and then the lid is placed on top, with the lid and base secured by snaps or adhesive tape. Takeout meals mostly use disposable plastic containers. The food is placed inside the bottom of the plastic container, and then a plastic lid is placed on top, its edge snapping into the bottom. Currently, neither cake nor takeout meal packaging has tamper-proof features. Third parties could easily open the containers, add foreign objects, or even maliciously poison them, threatening consumer safety and seriously undermining public trust. Therefore, we propose a new type of disposable, tamper-proof food packaging box. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a novel disposable, tamper-proof food packaging box.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel disposable, tamper-proof food packaging box, comprising a bottom box and a top cover. The bottom box has an inclined box wall, and the inclined box wall has several folding teeth at the edge of the bottom box opening. The top cover has a pressing edge groove at its opening. When the top cover is placed into the bottom box opening, the upper edge of the pressing edge groove of the top cover is lower than the root of the folding teeth of the bottom box. The folding teeth of the bottom box fold towards the pressing edge groove of the top cover, thereby fixing the top cover to the bottom box.
[0005] To further elaborate, the bottom box has at least two external tear lines on the outer wall of the inclined box wall, with each pair of external tear lines forming a group. A hand-tearable part is provided between the two external tear lines. When tearing the hand-tearable part, the bottom box can be torn open along the two external tear lines.
[0006] To further elaborate, the inner wall of the inclined box wall of the bottom box is provided with an inner knife line, and two inner knife lines are provided between every two outer tear lines, and the inner knife lines are parallel to the outer tear lines.
[0007] To further elaborate, the tilt angle of the inclined box wall of the bottom box is α, where 1°≤α<45°.
[0008] To further elaborate, when 1°≤α≤10°, the inclined box wall of the bottom box is provided with an annular inner convex edge, and when the top cover is placed into the opening of the bottom box, the annular inner convex edge supports the top cover.
[0009] To elaborate further, the toothed portion of the bottom box is provided with a half-cutting line.
[0010] The beneficial effects of this utility model are as follows: This utility model achieves sealing between the bottom box and the top cover by folding the toothed part of the bottom box over the pressing edge groove of the top cover. It is suitable for packaging food such as rice balls, pastries, and takeaway meals, preventing others from opening the food box at will and ensuring the food safety of the packaged food.

[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0020] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 4As shown, a novel disposable, tamper-proof food packaging box includes a base box 10 and a top cover 20. The base box 10 has an inclined box wall 11, and the inclined box wall 11 has several inwardly folding teeth 12 at the edge of the box opening. The top cover 20 has a pressing edge groove 21 at the opening. Figure 4 As shown, when the top cover 20 is placed into the opening of the bottom box 10, the upper edge 211 of the pressing ring groove 21 of the top cover 20 is lower than the root 121 of the toothed part 12 of the bottom box 10; the toothed part 12 of the bottom box 10 folds over the pressing ring groove 21 of the top cover 20, thereby fixing the top cover 20 to the bottom box 10.
[0021] This utility model is applicable to the packaging of foods such as rice balls and pastries. The bottom box 10 is made of coated paper cups, and the top cover 20 can be made of plastic. If this utility model is applied to ice cream, a wafer cone is also required below the ice cream, with the ice cream contained within the wafer cone, which is placed inside the bottom box 10. (See attached...) Figure 1 As shown, the shape of this utility model can be circular, or it can also be an appendix. Figure 5 The square shown, with Figure 1 and attached Figure 5 The shapes shown can all be used for packaging rice balls, pastries, and other foods. Furthermore, this invention can also be applied to takeout meals, as shown in the attached... Figure 6 and attached Figure 7 As shown, the structure of this utility model can prevent others from opening the lunch box at will, and avoid others from maliciously putting foreign objects or even poisoning it.
[0022] As attached Figure 4 As shown, after the folded teeth 12 of the bottom box 10 folds over the pressing ring groove 21 of the upper cover 20, the bottom box 10 and the upper cover 20 are sealed together. If you want to open the upper cover 20 later, you can only manually pry out the folded teeth 12 of the bottom box 10 one by one from the pressing ring groove 21 of the upper cover 20. It is easy for pry marks to appear at the folded teeth 12 of the bottom box 10.
[0023] Additionally, as attached Figure 4 As shown, a half-cut line 122 can be provided at the zigzag part 12 of the bottom box 10. When the zigzag part 12 of the bottom box 10 is pried out from the pressing ring groove 21 of the top cover 20, the zigzag part 12 of the bottom box 10 will break at the half-cut line 122, making the traces of it being opened more obvious.
[0024] As attached Figure 1As shown, the outer wall of the inclined box wall 11 of the bottom box 10 is provided with at least two external tear lines 111, with each pair of external tear lines 111 forming a group. A hand-tearable part 113 is provided between the two external tear lines 111. When the hand-tearable part 113 is pulled, the bottom box 10 can be torn open along the two external tear lines 111. Since the bottom box 10 and the top cover 20 are fixedly connected by the toothed part 12, directly opening and prying out the toothed part 12 is too inconvenient. However, by setting external tear lines 111 on the outer wall of the bottom box 10, the paper bottom box 10 can be torn open along the external tear lines 111 by manually pulling the hand-tearable part 113.
[0025] Additionally, as attached Figure 1 As shown, to ensure that the paper strip torn from the bottom box 10 is a continuous strip, an inner knife line 112 is provided on the inner wall of the inclined box wall 11 of the bottom box 10. Two inner knife lines 112 are provided between every two outer tear lines 111, and the inner knife lines 112 are parallel to the outer tear lines 111. When the hand-tearable part 113 is manually pulled, the outer wall of the bottom box 10 is torn along the outer tear line 111, and the inner wall of the bottom box 10 is torn along the inner knife line 112, thereby ensuring that the paper strip torn from the bottom box 10 is a continuous strip without any discontinuity.
[0026] Combined with appendix Figure 3 As shown, the tilt angle of the inclined box wall 11 of the bottom box 10 is α, where 1°≤α<45°. The tilt angle α of the inclined box wall 11 of the bottom box 10 is an important factor affecting the relative assembly relationship between the top cover 20 and the bottom box 10. If the tilt angle α is too small, the inclined box wall 11 of the bottom box 10 will be relatively steep. When the top cover 20 is placed into the opening of the bottom box 10, the lower side of the top cover 20 cannot be placed on the inclined box wall 11 of the bottom box 10, and the entire top cover 20 may sink directly into the bottom of the bottom box 10.
[0027] Additionally, for cases where 1°≤α≤10°, an annular inner protrusion 13 can be provided on the inclined box wall 11 of the base box 10. When the top cover 20 is placed into the opening of the base box 10, the annular inner protrusion 13 supports the top cover 20. The annular inner protrusion 13 can improve the supporting effect of the base box 10 on the top cover 20, preventing the entire top cover 20 from sinking directly into the bottom of the base box 10.
[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
