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.

本公司所生產制造實用新型的目的是，用整張紙折疊成型一個餐盒，其結構能使盒蓋蓋緊在盒體上，密封性好，同時又使用方便衛生。

The purpose of the utility model produced and manufactured by the company 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, convenient and sanitary use at the same time.

本公司所生產制造實用新型的產品是這樣實現的，它包括連為一體的盒蓋和盒體，其特征在于，它是由一整張成型的紙折疊而成的，其中盒蓋的前壁兩端有向外延伸的護翼，折疊后可夾在盒蓋的兩側壁上，以便在蓋上時將盒蓋的前壁拉緊。

The product of the utility model produced and manufactured by the company 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.

在盒體成型后，其四角的多余部分向外折疊并固定在盒體側壁的外翻邊上，使盒兩壁加強，使盒體內表面光滑；盒體的一邊有向外折疊的活飛邊，盒蓋蓋上后，即起封密作用，又撐緊盒蓋，使盒蓋不易自動脫開，同時也使盒體前壁加強。

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.
