FIELD: process engineering.SUBSTANCE: proposed paper cup has inner volume composed of tubular tapered wall and bottom wall connected with the latter nearby tubular wall bottom end, on its inner side, in fact, impermeable for fluid. The tubular wall restricting the inner volume comprises at least one peripheral deforming section, in the area of which there is a strengthening facility to stabilise this section. The group of inventions makes it possible to avoid deformation of the paper cup as a result of strengthening of the deforming section.EFFECT: ruled out cup deformation.14 cl, 11 dwg |
