目前，由于餐饮业广泛使用泡沫塑料(聚苯乙烯)制成的一次性快餐盒，造成了多处严重的白色污染，国家将逐步禁止生产和使用，提倡使用易于腐化、卫生、安全的纸制餐具，以附合环保要求。但用专用设备和材料生产纸饭盒，具有设备投资大、产品成本高、外形不美观、盒体软弱、盒盖不易盖紧固定、密封性差等缺点，因而难以推广普及。

At present, the disposable fast food boxes made of foamed plastics (polystyrene) are widely used in the catering industry, causing serious white pollution in many places. The state will gradually prohibit the production and use, and advocate the use of paper tableware that is easy to decay, hygienic and safe, so as to meet the requirements of environmental protection. However, the production of paper lunch boxes with special equipment and materials has many disadvantages, such as large equipment investment, high product cost, unsightly appearance, weak box body, difficult to close and fix the box cover, poor sealing, etc., so it is difficult to popularize.

这里提供一种可用普通机械和薄纸板制成的快餐盒，不但降低其设备投资和产品成本，而且力求在外形和使用效果上与泡沫塑料快餐盒相似。

The utility model provides a fast-food box which can be made of ordinary machinery and thin cardboard, which not only reduces the equipment investment and product cost, but also strives to be similar to the foam plastic fast-food box in appearance and use effect.

将纸板用一般制盒设备(如模切机等)按一定的图形，进行模切、压痕，使盒盖和盒体成型在一整张纸板上，再通过折叠、固定，分别将盒盖和盒体制成两个不等梯形体，且两口相对。其间相连处的活动折线为两道，以使盒盖开合自如，并通过折边增强盒体强度、增加美感、提高密封效果。

Use general box making equipment (such as die-cutting machine) to perform die cutting and indentation on the paperboard according to a certain figure, so that the box cover and box body are formed on a whole piece of paperboard, and then through folding and fixing, the box cover and box body are respectively made into two unequal ladder shapes with two opposite ports. There are two movable fold lines at the connecting part, so that the box cover can be opened and closed freely, and the strength of the box body can be enhanced, the aesthetic feeling can be increased, and the sealing effect can be improved through folding.

该餐盒两个梯形体的外形及大小比例与泡沫塑料餐盒基本相同本新型另一显著特征是在盒体前壁折边的中部，延伸有舌状凸出，它能被人为的伸入盒盖前壁中下部的槽口之内，故能将盒盖紧密的固定封闭在盒体上。从而达到与泡沫塑料快餐盒使用效果及外形相似的目的。

The shape and size ratio of the two trapezoidal bodies of the lunch box are basically the same as that of the foam plastic lunch box. Another notable feature of the new model is that there is a tongue shaped projection extending in the middle of the folding of the front wall of the box body, which can be artificially extended into the notch at the middle and lower part of the front wall of the box cover, so the box cover can be tightly fixed and closed on the box body. So as to achieve the purpose of using effect and shape similar to the foam plastic fast food box.

由于上述方案的实施，使本新型的工业化生产具有设备投资小、产品成本低、使用效果好、外形美观、盒体强度大、密封性好、合上盒盖后不会脱开、符合人们的传统使用习惯、丢弃后易于腐化等优点。而且，由于可在纸上印刷彩色图案，更能给人们以视觉上的享受，故尔能使人们乐于接受，从而完全取代用泡沫塑料制成的快餐盒，彻底解决由此带来的白色污染。

Due to the implementation of the above scheme, the new type of industrial production has the advantages of small equipment investment, low product cost, good use effect, beautiful appearance, high box strength, good sealing, no separation after closing the box cover, conforming to people's traditional use habits, easy to decay after discarding, etc. Moreover, because the color pattern can be printed on paper, which can give people more visual enjoyment, it can make people happy to accept it, so as to completely replace the fast-food box made of foam plastic and completely solve the white pollution caused by it.

一次性纸餐盒这里的制作方法就是用普通薄纸板作材料,按一定的图形进行模切、压痕,再经过折叠、固定等工序,制成两个不等梯形体的盒盖和盒体。由于在盒体前壁折边上有舌状凸出,可方便的插入盒盖前壁槽口之内,使得盒盖紧密的封闭固定在盒体上,然后,使有防潮灭菌功效的专用防渗剂喷涂成膜于盒体表面。

The manufacturing method of disposable paper lunch box here is to use ordinary thin paper board as material, carry out die cutting and indentation according to certain graphics, and then fold and fix it to make two unequal ladder shaped box covers and boxes. Because there is a tongue like projection on the folding edge of the front wall of the box body, it can be conveniently inserted into the notch of the front wall of the box cover, so that the box cover is tightly closed and fixed on the box body, and then the special anti-seepage agent with moisture-proof and sterilization effect is sprayed on the surface of the box body.
