FIELD: mechanical engineering; packing machines with device for internal ventilation of product reservoir. SUBSTANCE: packing machine has dispensing tube whose first end comes from first hole of product reservoir, and air collector with for dispensing tube designed for connection of second end of dispensing tube. Air collector gets under second end of dispensing tube. Vent tube is connected with second hole of product reservoir and with hole for vent tube in air collector. Dispensing tube and vent tube are separately connected with product reservoir and with air collector. Air pressure built at operation of packing machine is directed from air collector through vent tube into product reservoir. This air passes through vent tube and forces product out of reservoir in process of dispensing of product into packs. EFFECT: provision of sterility at packing, simplified design and easy servicing of product reservoir ventilation system. 2 cl, 5 dwg
