FIELD: manufacture of containers. SUBSTANCE: device for working of internal surface of plastic bottle 1 with the aid of plasma technology comprises vacuum chamber 2, microwave trap 3 with microwave generator 4, aids 5 for vacuuming and gas supply. Microwave trap 3 has cylindrical form satisfying as far as possible form of body part of bottle 1. Microwave radiation is fed from side of bottle 1 into microwave trap and microwave traps gets excited by mode of ThM resonance. Device is very compact and simple in design. Device can be built into gear for oriented forming by inflation or into bottling gear. In case of full-scale production assemblage of single-bottle devices can be arranged in row or make up matrix and all single-bottle devices can be connected to power network, vacuuming and gas supply lines. Each single-bottle device can include its own vacuum chamber or assemblage of microwave traps 3 can be integrated in one common vacuum chamber. EFFECT: enhanced quality of working of internal surfaces of plastic bottles and raised productivity of process. 15 cl, 8 dwg
