摘要： An article and a method are disclosed for substantially removing surfaces defects that are attendant with plastic blanks formed by cutting out squares from sheet stock material that are subsequently forged by means of non-melt, high pressure or solid-phase forming of preforms and thereafter thermoforming said preforms into containers. The blank itself comprises a tabular body having a pair of major faces located substantially parallel to one another, minor faces integrally formed and extending outwardly from said major faces, said minor faces presenting a smooth surface commensurate to that of said major faces, and a vertical portion integrally formed with said minor faces and defining an outer peripheral band or line having an unsmooth surface. A method of forming said plastic blank comprises providing a sheet of polymeric material, pressing lines of demarkation upon said sheet, severing said sheet within said lines to separate and cut said sheet into individual blank, whereby each blank is formed having a smooth surface provided by said pressing step and a rough surface provided by said severing step, thereafter forging said blank to a predetermined preform and reforming said preform to a container free of any imperfection.
摘要翻译：公开了一种用于基本上去除表面缺陷的制品和方法，所述缺陷是由通过从预成型件的非熔体，高压或固相形成随后锻造的片材原料切出正方形而形成的塑料坯料，然后热成型所述预成型件形成容器。坯料本身包括具有一对基本上彼此平行的主面的平板体，小面整体形成并从所述主面向外延伸，所述小面具有与所述主面相当的平滑表面，垂直方向部分与所述小面一体地形成，并且限定具有不平滑表面的外周带或线。形成所述塑料坯料的方法包括提供聚合物材料片材，在所述片材上挤压划线，在所述线材内切断所述片材以将所述片材分离并切割成单个毛坯，由此形成每个坯料具有由所述压制步骤和由所述切割步骤提供的粗糙表面，然后将所述坯料锻造到预定的预成型件，并将所述预成型件重整成没有任何缺陷的容器。
