FIELD: process engineering.SUBSTANCE: in compliance with this invention container is made from cardboard blank A. Note here that said container has bottom and side walls 7 extending upward from bottom. At final stage of container compression moulding, bead 8 is moulded from moulding material to extend sideways. Said bead is moulded on sidewall top section when die is retained closed so that die cavity 7 fitting in said bead is formed by displacement of its counter surface inside die backward from opposite surface. Thereafter moulding material is forced in die cavity 5.EFFECT: invention relates to package thus made.2 cl, 7 dwg |
