FIELD: process engineering.
SUBSTANCE: proposed invention covers nozzle and device intended for decreasing the volume of disposable vessels, particularly, disposable plastic bottles for drinks. Proposed device comprises device 9 partially communicated with inner space of disposable vessel to evacuate it, thus reducing its volume. Note here that said device 9 is communicated with nozzle 4 via lines/adapters 5, 6 and/or via, at least, extra one connection sleeve. Nozzle 4 is connected to the flange in disposable vessel opening via adapter 11. Note also that said adapter 11 is connected with nozzle 4 and/or flange and may be replaced by sleeve 12.
EFFECT: nozzle 4 used together with device facilitates decreasing disposable vessel volume.
