目前，由于餐飲業廣泛使用泡沫塑料(聚苯乙烯)制成的一次性快餐盒，造成了多處嚴重的白色污染，國家將逐步禁止生產和使用，提倡使用易于腐化、衛生、安全的紙制餐具，以附合環保要求。但用專用設備和材料生產紙飯盒，具有設備投資大、產品成本高、外形不美觀、盒體軟弱、盒蓋不易蓋緊固定、密封性差等缺點，因而難以推廣普及。

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.

這里提供一種可用普通機械和薄紙板制成的快餐盒，不但降低其設備投資和產品成本，而且力求在外形和使用效果上與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.

將紙板用一般制盒設備(如模切機等)按一定的圖形，進行模切、壓痕，使盒蓋和盒體成型在一整張紙板上，再通過折疊、固定，分別將盒蓋和盒體制成兩個不等梯形體，且兩口相對。其間相連處的活動折線為兩道，以使盒蓋開合自如，并通過折邊增強盒體強度、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.

該餐盒兩個梯形體的外形及大小比例與泡沫塑料餐盒基本相同本新型另一顯著特征是在盒體前壁折邊的中部，延伸有舌狀凸出，它能被人為的伸入盒蓋前壁中下部的槽口之內，故能將盒蓋緊密的固定封閉在盒體上。從而達到與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.

由于上述方案的實施，使本新型的工業化生產具有設備投資小、產品成本低、使用效果好、外形美觀、盒體強度大、密封性好、合上盒蓋后不會脫開、符合人們的傳統使用習慣、丟棄后易于腐化等優點。而且，由于可在紙上印刷彩色圖案，更能給人們以視覺上的享受，故爾能使人們樂于接受，從而完全取代用泡沫塑料制成的快餐盒，徹底解決由此帶來的白色污染。

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.

一次性紙餐盒這里的制作方法就是用普通薄紙板作材料,按一定的圖形進行模切、壓痕,再經過折疊、固定等工序,制成兩個不等梯形體的盒蓋和盒體。由于在盒體前壁折邊上有舌狀凸出,可方便的插入盒蓋前壁槽口之內,使得盒蓋緊密的封閉固定在盒體上,然后,使有防潮滅菌功效的專用防滲劑噴涂成膜于盒體表面。

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.
