The present invention provides a method and device for producing a content filling bottle including a bottom part that is inverted between a concave shape and a convex shape to prevent a body part from being subjected to reduced pressure deformation, the method and device being capable of efficiently producing a sanitary and high-quality content filling bottle. Contents are filled into an empty bottle 1 with an inversion part 11 projecting outwardly from the body part. A cap 6 is fitted onto an opening of the bottle 1 to seal the bottle 1. An auxiliary tool 27 is then installed on the bottom part 5 of the bottle 1. Then, the bottom part of the bottle 1 with the auxiliary tool 27 installed thereon is supported via the auxiliary tool 27. The downwardly projecting inversion part 11 is pressed up so as to be inverted and recessed inwardly into the bottle 1. Subsequently, with the opening of the bottle 1 gripped, the auxiliary tool 27 is separated from the bottle 1.

1. A method for producing a content filling bottle, in which liquid contents are sealed inside a synthetic resin bottle, said bottle comprising a hollowed body part, an opening formed at an upper end of the body part and onto which a cap is capable of being fitted, a shoulder part formed below the opening on an upper portion of the body part, a bottom part closing a lower end of the body part, and an inversion part formed in a portion of the bottom part so as to project outwardly from the body part in an axial direction of the body part, the inversion part being capable of being inverted and recessed inwardly into the body part in the axial direction thereof, the method comprising: a content filling step in which liquid contents are filled into an interior of the empty bottle with said inversion part projecting outwardly from the body part and with the contents not filled therein yet, anda sealing step in which the cap is fitted onto the opening of the filled bottle with the liquid contents filled therein in the content filling step to seal the bottle, the method further comprising:a bottle retaining step performed after the sealing step, the bottle retaining step fitting a pair of pressing concave parts with shapes corresponding to the shoulder part of the bottle around opposite sides of the shoulder part of the filled bottle, thereby gripping the bottle so that the bottle is inhibited from moving in a vertical direction; anda bottom part recessing step in which said inversion part of the bottom part of the filled bottle retained in the bottle retaining step is pressed up so as to be inverted and recessed inwardly into the bottle. 2. The method for producing a content filling bottle according to claim 1, wherein in said bottle retaining step, the bottom part of the bottle except for the inversion part is retained simultaneously with the gripping of the shoulder part on the upper portion of the body part of the filled bottle with the cap that was previously fitted thereon in said sealing step, wherein the shoulder part on the upper portion of the body part is continuous with the opening. 3. The method for producing a content filling bottle according to claim 1, wherein in said content filling step, the contents heated to a predetermined temperature are filled into the empty bottle. 4. The method for producing a content filling bottle according to claim 1, wherein in said content filling step, the contents at an ordinary temperature are filled into the empty bottle. 5. The method for producing a content filling bottle according to claim 1, wherein the body part of the bottle includes an annual bead extending around a circumference thereof, and the bottle retaining means includes a pair of engaging convex parts formed respectively below the pressing concave parts, the pair of engaging convex parts engaging portions of an annular bead on the opposite sides of the bottle. 6. A device for producing a content filling bottle, in which liquid contents are sealed inside a synthetic resin bottle, said bottle comprising a hollowed body part, an opening formed at an upper end of the body part and onto which a cap is capable of being fitted, a shoulder part formed below the opening on an upper portion of the body part, a bottom part closing a lower end of the body part, and an inversion part formed in a portion of the bottom part so as to project outwardly from the body part in an axial direction of the body part, the inversion part being capable of being inverted and recessed inwardly into the body part in the axial direction thereof, the device comprising: content filling means for filling liquid contents into an interior of the empty bottle with the inversion part projecting outwardly from the body part and with the contents not filled therein yet;sealing means for fitting the cap onto the opening of the filled bottle with the liquid contents filled therein by the content filling means to seal the bottle;bottle retaining means having a pair of pressing concave parts with shapes corresponding to the shoulder part of the bottle, the pressing concave parts fitting around opposite sides of the shoulder part of the filled bottle, in order to grip the bottle so that the bottle is inhibited from moving in a vertical direction; andbottom part recessing means for pressing up said inversion part of the bottom part of the filled bottle retained by the bottle retaining means, so as to invert and recess said inversion part inwardly into the bottle. 7. The device for producing a content filling bottle according to claim 6, wherein said bottle retaining means further comprises bottom part supporting means for supporting the bottom part of the filled bottle, the bottom part supporting means being provided below the pair of pressing concave parts, and the bottom part supporting means comprises a supporting concave part corresponding to the bottom part of the bottle and an opening part that is open in a lower bottom portion thereof corresponding to said inversion part. 8. The device for producing a content filling bottle according to claim 6, wherein said content filling means fills the contents heated to a predetermined temperature into the empty bottle. 9. The device for producing a content filling bottle according to claim 6, wherein said content filling means fills the contents at an ordinary temperature into the empty bottle. 10. The device for producing a content filling bottle according to claim 6, wherein the body part of the bottle includes an annual bead extending around a circumference thereof, and the bottle retaining means includes a pair of engaging convex parts formed respectively below the pressing concave parts, the pair of engaging convex parts engaging portions of an annular bead on the opposite sides of the bottle.
