对于保鲜餐盒，目前的餐盒主要分为塑料餐盒和纸餐盒。一般是将食物放在盒子里，再盖上一层保鲜膜，形成保鲜饭盒结构。那么要如何制作纸餐盒？

For fresh-keeping lunch boxes, the current lunch boxes are mainly divided into plastic lunch boxes and paper lunch boxes. Generally, food is put in a box and covered with a layer of fresh-keeping film to form a fresh-keeping lunch box structure. So how to make a paper lunch box?

具体技术方案为：一种便于堆叠的一次性纸餐盒，包括由整块纸板切割后挤压而成的盒体，所述盒体包括底壁、至少三个侧壁和与侧壁相等的围壁，所述围壁与侧壁相邻设置，所述围壁由纸板上相邻且分离的切割边重叠并通过挤压模具挤压而成。

The specific technical scheme is: a disposable paper lunch box that is easy to stack, including a box body formed by extrusion after cutting a whole piece of paperboard, the box body includes a bottom wall, at least three side walls and an enclosure wall equal to the side wall, the enclosure wall is adjacent to the side wall, and the enclosure wall is formed by overlapping adjacent and separated cutting edges on the paperboard and extrusion through an extrusion die.

此外，至少一个围壁的内侧表面或外侧表面在挤压模具的挤压成型过程中形成有凸起，以在堆叠多个盒子时留出间隙。包括通过吸塑工艺覆盖在盒体内表面上的薄膜层，至少部分围壁由两层纸板叠合在挤压模具上挤压而成。

In addition, the inner surface or outer surface of at least one enclosure wall forms a bulge during the extrusion molding process of the extrusion die to leave a gap when stacking a plurality of boxes. The utility model comprises a film layer covered on the surface of the box body through a plastic absorption process, and at least part of the enclosure wall is formed by superimposing two layers of cardboard on the extrusion die.

箱体包括四个侧壁和四个围壁，底壁为圆弧形过渡的四边形，四个侧壁连接到底壁的四个边上，四个围壁连接到底壁的四个角位上，围壁由相邻侧壁的刃口在角位处重叠而成。四个侧壁的刃口均形成有片状部，片状部被动层压在挤压模具中的相邻侧壁上形成层压区，凸起形成在层压区中。

The box body consists of four side walls and four enclosure walls. The bottom wall is a quadrangle with arc transition. The four side walls are connected to the four sides of the bottom wall, and the four enclosure walls are connected to the four corners of the bottom wall. The enclosure wall is formed by overlapping the cutting edges of adjacent side walls at the corners. The cutting edges of the four side walls are formed with sheet parts, which are passively laminated to form a lamination area on the adjacent side walls in the extrusion die, and the bulges are formed in the lamination area.

片材的外边缘还设有延伸部，该延伸部叠置在相邻的侧壁上。四个侧壁和环绕壁的外边缘也向外翻以形成凸缘，并且薄膜层的外围结合到凸缘。每个围壁的内表面形成有凸起，每个围壁的外表面形成有凸起。

The outer edge of the sheet is also provided with an extension part, which is superimposed on the adjacent side wall. The outer edges of the four side walls and the surrounding walls are also turned outward to form a flange, and the periphery of the film layer is bonded to the flange. The inner surface of each enclosure wall forms a bulge, and the outer surface of each enclosure wall forms a bulge.

上述便于堆叠的一次性纸餐盒的有益效果是：该便于堆叠的纸餐盒盒体包括底壁、侧壁和围壁，围壁上设有凸起，使得多个纸质饭盒间隔堆叠，解决了机械臂的爪子或气爪难以逐个抓取纸质饭盒的问题，从而实现了生产线的自动化生产，不良率大大降低，操作人员无需实时辅助机械臂一个个抓取纸质饭盒，大大减轻了操作人员的工作量。

The beneficial effect of the disposable paper lunch box that is easy to stack is that the box body of the paper lunch box that is easy to stack includes a bottom wall, a side wall and an enclosure wall, and the enclosure wall is provided with a bulge, so that multiple paper lunch boxes are stacked at intervals, which solves the problem that it is difficult for the claws or air claws of the mechanical arm to grasp the paper lunch boxes one by one, thus realizing the automatic production of the production line and greatly reducing the defect rate, The operator does not need to assist the manipulator to grasp the paper lunch boxes one by one in real time, which greatly reduces the workload of the operator.
