At present, "disposable food containers" are usually made of paper, so there are also "disposable paper containers" "And "disposable paper containers" etc.
习知常见的纸制容器是以纸片为材料,由弯折、层叠、压轧等手段,制造出围绕成一圈的本体及一结合于底部的底片,由该本体及该底片所共同界定出的容积范围即为一盛装空间,该本体的纸片底部与该底片的纸片周缘间是经由层叠及压轧的手段达成结合作用,以围覆出一底部空间,该本体的纸片顶部则经由向外弯折的手段产生出一顶缘,也因此在该顶缘的内部一定会存在一空隙。习知纸制容器因为只是以薄片状的纸片为材料制成,所以在无其他更佳替代品的情形下,勉强被采用来盛装热食(热汤或热咖啡、热茶等),但其实习知纸制容器在实际使用时存在着防烫效果差、耐热效果不佳、遇热易软化(尤其顶缘更是容易软化)及底部难以散热等诸项缺失。The conventional paper container is made of paper as a material, by means of bending, lamination, pressing, etc., a body surrounded by a circle and a bottom sheet combined with the bottom are manufactured, which are jointly defined by the body and the bottom sheet The volume range of the main body is a containing space. The bottom of the paper sheet of the main body and the periphery of the paper sheet of the negative sheet are combined to form a bottom space by means of lamination and rolling. The top of the paper sheet of the main body is A top edge is created by bending outwards, and therefore there must be a gap inside the top edge. Conventional paper containers are only made of thin sheets of paper, so they are barely used to hold hot food (hot soup or hot coffee, hot tea, etc.) when there is no better alternative. His practice knows that paper containers have poor anti-scalding effect, poor heat resistance effect, easy softening when exposed to heat (especially the top edge is easy to soften), and the bottom is difficult to dissipate heat.
在“物资循环”、“绿色环保”、“友善地球”的大自然环境要求下,申请人已经研发出由“纸塑产品的制造技术”制造而成的「防烫纸塑容器」产品,将可逐步取代习知常见的纸制容器。所指的“纸塑产品的制造技术”,概略而言,是以纸浆纤维材料及/或含括植物纤维材料混合打浆为浆质材料注于浆槽内,然后由一吸浆模进入该浆槽内吸浆附着为一浆料层,将该浆料层经过挤压脱水成为 一初胚品,再将该初胚品经过热压定型成为纸塑产品。Under the natural environment requirements of “material recycling”, “green environmental protection”, and “earth-friendly”, the applicant has developed a “anti-scalding paper-plastic container” product manufactured by “manufacturing technology of paper-plastic products”. It can gradually replace conventional paper containers. The "manufacturing technology of paper-plastic products" referred to, roughly speaking, is based on mixing pulp fiber materials and/or including plant fiber materials as the pulp material into the pulp tank, and then enters the pulp from a suction mold The slurry suction in the tank is attached to a slurry layer, the slurry layer is squeezed and dehydrated into a primary embryo, and then the primary embryo is shaped into a paper-plastic product through hot pressing.
