FIELD: process engineering.SUBSTANCE: packing material 2 comprises, at least, first 4 and second 5, 6 layers, channel 9 formed in first layer 4 and compacted by covering section 10 of second layer 5, 6. In compliance with proposed method, fused plastic material is injected to first side 10a of covering section 10 of second layer 5, 6 and fed along covering section 10 to cover it on first side 10a. Then fused plastic material is fed via circular peripheral section of covering section 10 to make chute 12 of opening device 3 extending from second side 10b opposite first side 10a of covering section 10. Note here that said fused plastic material covers covering section 10 to make compacting section 15 of chute 12 to be removed by user.EFFECT: tight container for fluid food products.15 cl, 7 dwg |
