日常外卖中，为了方便携带，需要将多个纸质外卖打包盒叠放在一起。通常纸质餐盒使用的塑料上盖或纸质上盖比较柔软，当纸质餐盒所装食物较重时，下方餐盒的上盖因为无法承受上方叠放餐盒的重量而受损，而且在运送过程中很容易打滑翻车。那么如何解决外卖打包盒密封性差、容易侧翻的问题？一次性外卖打包盒厂家为您提出建议：

In daily takeout, in order to facilitate carrying, multiple paper takeout boxes need to be stacked together. Usually, the plastic upper cover or paper upper cover used in the paper lunch box is relatively soft. When the food contained in the paper lunch box is heavy, the upper cover of the lower lunch box is damaged because it cannot bear the weight of the stacked lunch boxes above, and it is easy to slip and overturn during transportation. So how to solve the problem of poor sealing and easy overturning of the take out packaging box? The manufacturer of disposable take out packing boxes gives you suggestions:

为了克服上述问题，技术人员提供了一种环保外卖打包盒。该外卖打包盒采取的技术方案是：一种环保外卖打包盒，包括纸盒体和与纸盒体相互扣合的盒盖，纸盒体的上边缘设有上翘的卷边，卷边的横截面呈弧形，向外凸出的弧顶大致在高度的中间；

In order to overcome the above problems, the technician provides an environmental protection takeout packing box. The technical scheme adopted by the take out packing box is: an environmental protection take out packing box, which includes a carton body and a lid that is interlocked with the carton body. The upper edge of the carton body is provided with an upturned curl. The cross section of the curl is arc-shaped, and the outwardly protruding arc top is approximately in the middle of the height;

纸盒体的底面凹陷形成台阶面，纸盒体的下缘作为支撑脚支撑下方叠放的纸质餐盒；盒盖包括纸板和边框，纸板的外缘通过注塑连接有由可生物降解材料制成的边框，边框具有垂直于纸板的侧壁和平行于纸板的顶面，边框的侧壁内侧具有相对于侧壁自上而下凸起的斜面；斜面的底部连接有凸起的卡肋，卡肋基于框架的侧壁向内突出，卡肋的顶部高于斜面底部的凸起高度；

The bottom surface of the carton body is recessed to form a step surface, and the lower edge of the carton body serves as a support foot to support the paper lunch boxes stacked below; The box cover comprises a cardboard and a frame, the outer edge of the cardboard is connected with a frame made of biodegradable material by injection molding, the frame has a side wall perpendicular to the cardboard and a top surface parallel to the cardboard, and the inner side of the side wall of the frame has a slope raised from top to bottom with respect to the side wall; The bottom of the inclined surface is connected with a convex rib, the rib protrudes inward based on the side wall of the frame, and the top of the rib is higher than the convex height of the bottom of the inclined surface;

斜面下部与纸箱体侧壁之间的距离小于弧形顶部与纸箱体侧壁之间的距离，夹杆端部与纸箱体侧壁之间的距离略小于弧形顶部与纸箱体侧壁之间的距离，夹条的凸顶与纸板之间的距离大于卷边高度的1/2且小于9/10，在扣合过程中夹条和斜面压住卷边的曲顶弹性变形并嵌入卷边中；

The distance between the lower part of the slope and the side wall of the carton body is less than the distance between the arc top and the side wall of the carton body, the distance between the end of the clamp rod and the side wall of the carton body is slightly less than the distance between the arc top and the side wall of the carton body, the distance between the convex top of the clamp strip and the cardboard is greater than 1 / 2 and less than 9 / 10 of the crimping height, and the curved top of the clamp strip and the slope pressing the crimping is elastically deformed and embedded in the crimping during the fastening process;

框架顶面的内侧设有向内延伸的桌面，桌面位于纸盒体的支脚下方，桌面设有突出的限位台阶，限位台阶环绕纸盒体设置，限制纸盒体的水平位移。外卖打包盒框架的内角为圆弧，圆弧两端之间的水平长度大于、等于或小于圆弧两端之间的垂直高度。

The inner side of the top surface of the frame is provided with an inwardly extending table top, which is located under the support foot of the carton body. The table top is provided with a protruding limit step, which is arranged around the carton body to limit the horizontal displacement of the carton body. The internal angle of the take out packing box frame is an arc, and the horizontal length between the two ends of the arc is greater than, equal to or less than the vertical height between the two ends of the arc.

外卖打包盒镜架内角为圆弧，分散应力，避免应力集中，降低了注射成型生物降解材料镜架的风险。圆弧两个端点之间的水平长度大于、等于或小于圆弧两个端点之间的垂直高度，框架内角的形状尽可能与卷边的弧度相匹配，既增加了框架的强度，又进一步增加了防漏性能。

The inner angle of the lens frame of the take out packing box is circular arc, which disperses the stress and avoids the stress concentration, reducing the risk of injection molding biodegradable material lens frame. The horizontal length between the two ends of the arc is greater than, equal to or less than the vertical height between the two ends of the arc. The shape of the inner corner of the frame is matched with the arc of the curling as much as possible, which not only increases the strength of the frame, but also further increases the leak proof performance.

生物降解材料价格昂贵，只需在纸板上注塑生物降解框架，成本相对较低，提高了市场竞争力。外卖打包盒框架上设有多个通孔，可以节省可生物降解的材料，同时框架美观。如果您需要定制或者想了解更多问题，就来我们网站http://www.sdynbz.com咨询了解吧！

The price of biodegradable materials is expensive, so only the biodegradable frame needs to be injected on the board, and the cost is relatively low, which improves the market competitiveness. A plurality of through holes are arranged on the frame of the take out packing box, which can save biodegradable materials and make the frame beautiful.
