In this state, the transverse sealing device 178 is raised to the position shown by the solid line, and the packaging material 107s is sandwiched by the drive-side seal block 179a and the fixed-side seal block 179b. The transverse seal portion Sy is formed on the upper portion of the tubular packaging material 107s sealed and cut to accommodate the drip bag 105 and the double package 103 is completed on the lower side.

Next, while the drive-side seal block 179a and the fixed-side seal block 179b are sandwiched by the packaging material 107s, the transverse sealing device 178 is lowered from the state shown by the solid line to the state shown by the virtual line do. As a result, the packaging material 107s is pulled downward and drawn out by one pitch. The driving side seal block 179a is driven in a direction away from the fixed side seal block 179b to release the holding of the packing material 107s and the double packing material 103 is separated from the packing material 107s , Falls onto a conveyor (not shown), and is discharged out of the furnace by the conveyor.

As described above, since the inside of the packaging material 107s folded in half by the nitrogen gas supplied from the gas supply pipe 190 is filled with the nitrogen gas, the inside of the cover 107 is filled with the nitrogen gas State. Therefore, the drip bag 105 is enclosed in the surface seal 107 together with the nitrogen gas.

The above operation is carried out continuously, and the drip bag 105 is sealed in the surface seal 107, so that the double-layered package 103 is continuously produced.

The operation of forming the drip bag 105 by the inner package forming means 111 and the filling operation of the regular coffee Co are carried out by the operation of conveying the drip bag 105 of the inner package conveying means 115, The forming operation of the surface seal 107 of the body forming means 113 is controlled by control means (not shown) so as to be performed synchronously based on an electrical signal.
