FIELD: process engineering.
SUBSTANCE: invention relates to production of container connected with hand-driven fluid dispensing pump, fluids being contained in deformable bag arranged in stiff case. In compliance with this invention, stiff outer case is made with the neck for access to case inside. Blank is made from thermoplastic. Note here that said blank comprises neck with flange extending radially. Said blank is heated to temperature above thermoplastic softening point and fitted in the case hole. First air jet is forced into blank inside to blow out the blank to form the bag which fills, at least partially, the case inside. Note here that bag walls are squeezed to contact with walls that make said inside. Note also that during said air jet feed vacuum is applied to area between container inside inner and outer surfaces.
EFFECT: higher breaking strength of said bag at blow-out.
14 cl, 7 dwg
