A packaging machine comprises a filling device (13) for filling a tube T of packaging material having an open upper end and a closed lower end with contents in a predetermined amount at a time, and a device (14) for forming containers C by sealing and cutting the filled tube T transversely thereof into a length corresponding to one container at a time. The amount of contents to be filled into the container and the capacity of the container are so determined that the capacity is greater than the amount of contents to be filled.

Packaging machine

A packaging machine comprises a rotor 22 having radial mandrels 21 each adapted to carry a tubular blank 11 of square to rectangular cross section as fitted therearound and arranged to successively stop at a plurality of processing stations I to VIII, a group of devices 23 to 28 arranged respectively at the required stations among the processing stations I to VIII for folding and closing a container bottom forming end portion 14 of the blank 11 as fitted around the mandrel 21, and an air suction nozzle 31 for collecting extraneous matter is disposed at a required location along a path of movement of the mandrel.

A liquid filling device comprises a filling nozzle 31 for filling contents into containers C being transported by a conveyor 13, and a lifter 34 for lifting the container C to be filled from the path of transport of the conveyor. The filling nozzle 31 has a lower portion providing a vertical cylinder portion 42 fittable with the container C to be lifted by the lifter 34. The filling nozzle 31 is provided with an air cover 51 comprising a top wall and a peripheral wall extending downward from an edge portion of the top wall. The filling nozzle 31 extends through the top wall, with its vertical cylinder portion 42 projecting into the air cover 51. The air cover 51 has connected thereto an outlet end of a dry air pipe 52.

Liquid filling device

A filling nozzle comprising a vertical tubular nozzle body, and at least one perforated plate disposed at a lower-end opening of the nozzle body for preventing a liquid from flowing down under gravity by the surface tension of the liquid. The perforated plate has an opening degree varying from small to great from its center or the vicinity thereof toward its periphery or the vicinity thereof.

Filling nozzle

An apparatus for filling a specified amount of liquid comprising a metering cylinder having a piston therein, a vertical filling nozzle having an open lower end and feedable with a liquid from the metering cylinder by the operation of the piston, a damper for opening and closing the open lower end of the filling nozzle, a spring biasing the damper to hold the nozzle end closed with the damper while the feed of the liquid is discontinued, and an opening portion adapted to open the damper against the spring simultaneously with or immediately before the start of feed of the liquid with the damper closed and to be subsequently brought out of operative relation with the damper before the feed of the liquid is discontinued so as to render the damper closable by the spring.
