2 '. As the above-mentioned ventilation sheet, moisture-proof sheet and powder, those used for ordinary disposable warmers and the like can be used.

In the method for manufacturing a fluid package according to the present embodiment, the first sheet (first
A predetermined amount of fluid 103 on a continuum 101 ') of sheets of
The first sheet is positioned on one surface (outer surface) 2a side of the measuring through-hole 21 of the fluid measuring body 2, and the measuring through-hole 21 is placed on the first sheet being conveyed. This is carried out by intermittently supplying the fluid 103 ′ from the other surface (inner surface) 2 b side through the measuring through hole 21.

In the fluid supply step, first, the driving roller 41 of the first sheet conveying means 4 is rotated in the direction shown by the arrow in FIG.
While being transported in the direction indicated by the middle arrow, the endless belt 45
The first sheet continuum 101 ′ is pressed against the fluid supply cylinder 31 to seal the outer surface of the supply opening of the measurement through-hole 21 with the first sheet continuum 101 ′. Thereby, a volume measuring section of the fluid is formed. Separately, the fluid 103 is charged into the fluid supply cylinder 31,
The fluid measuring body 2 is rotated in the direction indicated by the arrow in FIG.
The input amount of the fluid 103 is set to such an extent that the fluid 103 is sufficiently self-weighted and the fluid 103 is dropped and filled into the volume measuring section without any gap. When the fluid contains iron powder or the like, the fluid can be reliably filled regardless of its own weight by drawing and filling the fluid into the fluid measuring body 2 using a magnet. In the case where the fluid is a substance having a high viscosity, the fluid can be surely filled irrespective of its own weight by filling the fluid into the fluid supply cylinder 31 under pressure. When the measuring through-hole 21 of the rotating fluid measuring body 2 is located immediately below the fluid discharge port 3b, the fluid 103 is filled into the volume measuring section without any gap by its own weight. In this case, since the continuous body 101 'of the first sheet is pressed toward the scraping portion 32 by the endless belt 45, the fluid is filled into the volume measuring section in a fixed amount (constant volume), and the filling is performed. It proceeds very smoothly. When the rotation of the fluid measuring body 2 further proceeds, the inner surface of the supply opening of the measuring through-hole 21 is scraped off by the scraping portion 32. As a result, a fluid having an apparent volume substantially similar to the volume of the volume measuring section is filled in the volume measuring section.

When the rotation of the fluid measuring body 2 further proceeds, the continuous body 101 'of the first sheet conveyed while being in contact with one surface (outer surface) 2a of the fluid measuring body 2 separates from the one surface 2a. To go. At this time, the fluid 103 filled in the volume measuring section remains on the continuous body 101 'of the first sheet. As a result, the fluid 103 is supplied in a fixed amount (constant volume) onto the continuous body 101 'of the first sheet. Since the fluid 103 has a certain degree of shape retention, the first
The overall form of the fluid 103 remaining on the sheet continuum 101 ′ has substantially the same shape as the shape obtained by developing the volume measuring section on a plane.

As shown in FIG. 1, the magnet 42 is located on the surface of the continuum 101 'of the first sheet opposite to the surface on which the fluid 103 is supplied. The fluid 103 remaining on the continuum 101 'is better maintained in its overall form. Specifically, the magnet 42
Are provided in the drive roller 41 so as to correspond to the respective fluids 103, that is, to correspond to the metering through-holes 21, and as described above, the fluid 103 contains iron powder. As a result, the fluid 103 is conveyed in a state where its overall form is better maintained by the magnet 42. For this reason, the manufacturing method of the present embodiment is excellent in shape retention of the fluid. Also, after the fluid is left on the continuum 101 ′ of the first sheet, the continuum 10
The time to coat with 2 'is short and therefore the fluid 10
Since the whole form of 3 is hard to break, it is possible to package the fluid 103 in a free shape.

The continuous body 101 ′ of the first sheet on which the fluid 103 in a predetermined form is placed is conveyed toward the heat seal roller 51. Separately from this, the continuous body 102 ′ of the second sheet is conveyed by the heat seal roller 51. Heat seal roller 51
Are heated to a predetermined temperature. Then, the continuum 101 ′, 102 ′ of both sheets is formed by the heat seal roller 51.
And at the contact portion between the drive roller 41 and
Fluid 1 located on first sheet continuum 101 '
03 is covered by a second sheet continuum 102 '. At the same time, the continuity of the first sheet 10
1 'and the continuum of the second sheet 102'
3 is heat-sealed at the periphery to form a continuous body 100 'of the fluid package. Then, each fluid 10
3, the continuous body of the fluid package is cut in the width direction, and the fluid package obtained by cutting is sealed with a non-permeable film or the like to obtain a final product (FIG. Not shown).
