對于保鮮餐盒，目前的餐盒主要分為塑料餐盒和紙餐盒。一般是將食物放在盒子里，再蓋上一層保鮮膜，形成保鮮飯盒結(jié)構(gòu)。那么要如何制作紙餐盒？

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?

具體技術(shù)方案為：一種便于堆疊的一次性紙餐盒，包括由整塊紙板切割后擠壓而成的盒體，所述盒體包括底壁、至少三個側(cè)壁和與側(cè)壁相等的圍壁，所述圍壁與側(cè)壁相鄰設(shè)置，所述圍壁由紙板上相鄰且分離的切割邊重疊并通過擠壓模具擠壓而成。

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，至少一個圍壁的內(nèi)側(cè)表面或外側(cè)表面在擠壓模具的擠壓成型過程中形成有凸起，以在堆疊多個盒子時留出間隙。包括通過吸塑工藝覆蓋在盒體內(nèi)表面上的薄膜層，至少部分圍壁由兩層紙板疊合在擠壓模具上擠壓而成。

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.

箱體包括四個側(cè)壁和四個圍壁，底壁為圓弧形過渡的四邊形，四個側(cè)壁連接到底壁的四個邊上，四個圍壁連接到底壁的四個角位上，圍壁由相鄰側(cè)壁的刃口在角位處重疊而成。四個側(cè)壁的刃口均形成有片狀部，片狀部被動層壓在擠壓模具中的相鄰側(cè)壁上形成層壓區(qū)，凸起形成在層壓區(qū)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.

片材的外邊緣還設(shè)有延伸部，該延伸部疊置在相鄰的側(cè)壁上。四個側(cè)壁和環(huán)繞壁的外邊緣也向外翻以形成凸緣，并且薄膜層的外圍結(jié)合到凸緣。每個圍壁的內(nèi)表面形成有凸起，每個圍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.

上述便于堆疊的一次性紙餐盒的有益效果是：該便于堆疊的紙餐盒盒體包括底壁、側(cè)壁和圍壁，圍壁上設(shè)有凸起，使得多個紙質(zhì)飯盒間隔堆疊，解決了機械臂的爪子或氣爪難以逐個抓取紙質(zhì)飯盒的問題，從而實現(xiàn)了生產(chǎn)線的自動化生產(chǎn)，不良率大大降低，操作人員無需實時輔助機械臂一個個抓取紙質(zhì)飯盒，大大減輕了操作人員的工作量。

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.

針對現(xiàn)有技術(shù)中存在的上述問題，技術(shù)人員提供了一種便于堆疊的紙餐盒，以上便是相關(guān)的內(nèi)容了，更多信息獲取就來我們網(wǎng)站http://m.wxzaxf.com吧。
