一體成型淋膜餐盒One-piece laminating lunch box

本創作有關一種一體成型淋膜餐盒，尤指一種以蒸氣使餐盒紙胚具有延展性，使得成型餐盒具有足夠的結構強度。The present invention relates to a one-piece laminating lunch box, in particular to a vapour that makes the lunch box of the lunch box malleable, so that the molded lunch box has sufficient structural strength.

按，傳統的免洗餐具(一次性餐具)大都是塑膠製品、保麗龍 (聚苯乙烯)或紙類所製成，其中又以保麗龍(聚苯乙烯)所製成之免洗餐具，遇熱會排放出毒素，對人體健康有害，且該餐具無法自然分解，會造成環境的污染，因已經被很多國家禁止使用。According to the traditional disposable tableware (disposable tableware), most of them are made of plastic products, styrofoam (polystyrene) or paper, and the disposable tableware made of styrofoam (polystyrene). The heat will emit toxins, which are harmful to human health, and the tableware cannot be naturally decomposed, which will cause environmental pollution, which has been banned in many countries.

因此市場對紙製餐盒需求量大增，遂有業者不斷研發出各種不同結構之紙製餐盒。而傳統紙製餐盒之結構及製法，係如圖1A及1B所示，將紙板裁切成一預定形狀的餐盒紙胚60，該餐盒紙胚60具有盒底61、盒邊板62、四端角之摺片63及蓋體64等，上述各部位皆係相互連結為一體，經一成型模具熱壓合，使上述四端角之摺片63相互貼合，成為一立體紙製餐盒60A。Therefore, the demand for paper lunch boxes has increased greatly in the market, and many manufacturers have continuously developed paper lunch boxes of various structures. The structure and manufacturing method of the conventional paper lunch box are as shown in FIGS. 1A and 1B, and the paperboard is cut into a predetermined shape of a lunch box paper 60 having a box bottom 61 and a box side board 62. The four-end corner flap 63 and the lid body 64 are integrally connected to each other, and are thermocompression-bonded by a molding die to bond the four-end corner flaps 63 to each other to form a three-dimensional paper system. Lunch box 60A.

惟查，傳統紙製餐盒60A結構，其最大的問題點在於其熱壓合成型後的盒體61a或蓋體64a，因為紙板不具延伸性，所以無法像塑膠或保麗龍餐盒，可以一體成型具有凹凸之補強肋體或表面，因此成型後之紙製餐盒60A，其結構強度相對不足，承放食物時易產生變形；再者，其四端角之摺片63重疊後之結合面利用膠體予以黏著貼合，但此種黏合方式成型後之立體紙餐盒60A的結構較不牢固，若往兩相對框邊稍加施力外拉，容易導致端角之摺片63撕開或損壞，如此一來，當餐盒內盛裝菜餚湯汁時，容易從貼合處滲漏，是故，尚有改善空間。However, the traditional paper box 60A structure, the biggest problem lies in its hot-pressed type of box body 61a or cover body 64a, because the cardboard is not extensible, it can not be like plastic or styrofoam lunch box, can The reinforcing ribs or surfaces having irregularities are integrally formed, so that the formed paper lunch box 60A has a relatively insufficient structural strength, and is easily deformed when the food is placed; further, the combination of the four-corner flaps 63 is overlapped. The surface is adhered by a colloid, but the structure of the three-dimensional paper lunch box 60A formed by the bonding method is relatively weak, and if the two opposite sides of the frame are slightly applied, the flap 63 of the end corner is easily torn. Or damage, as a result, when the soup is contained in the lunch box, it is easy to leak from the fitting. Therefore, there is still room for improvement.
