At present, the snack boxes used mostly use plastic foam molding boxes, although they can also be used for one time, but after use, it is very difficult to deal with these wastes, and its accumulation will directly affect our ecological environment. Now, a large number of users are gradually switching to disposable paper lunch boxes, which have various shapes, such as barrel type, rectangular type, etc. However, due to the limitations of their shape and materials, the sealing between the box cover and the box body is poor and the cover is not tight, which is easy to make dust enter the food in the box, which is very unsanitary.

壹诺包装所生产制造实用新型的目的是，用整张纸折叠成型一个餐盒，其结构能使盒盖盖紧在盒体上，密封性好，同时又使用方便卫生。

The purpose of the utility model produced and manufactured by Yinuo Packaging Institute is to fold a whole piece of paper to form a lunch box. Its structure can make the box cover tightly on the box body, with good sealing performance and convenient and sanitary use.

壹诺包装所生产制造实用新型的产品是这样实现的，它包括连为一体的盒盖和盒体，其特征在于，它是由一整张成型的纸折叠而成的，其中盒盖的前壁两端有向外延伸的护翼，折叠后可夹在盒盖的两侧壁上，以便在盖上时将盒盖的前壁拉紧。

The product of the utility model produced by Yinuo Packaging Co., Ltd. is realized in this way, which comprises a box cover and a box body connected as a whole. It is characterized in that it is folded by a whole piece of formed paper, in which the two ends of the front wall of the box cover are provided with outward extending protective wings, which can be clamped on the two side walls of the box cover after folding, so as to tighten the front wall of the box cover when it is covered.

在盒体成型后，其四角的多余部分向外折叠并固定在盒体侧壁的外翻边上，使盒两壁加强，使盒体内表面光滑；盒体的一边有向外折叠的活飞边，盒盖盖上后，即起封密作用，又撑紧盒盖，使盒盖不易自动脱开，同时也使盒体前壁加强。

After the box body is formed, the excess parts of its four corners are folded outward and fixed on the outer turned edge of the side wall of the box body, so as to strengthen the two walls of the box and make the inner surface of the box smooth; One side of the box body is provided with a movable flash folded outward. After the box cover is covered, it not only plays a sealing role, but also supports the box cover tightly, so that the box cover is not easy to automatically disengage, but also strengthens the front wall of the box body.
