The method includes heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth. The first and second directions are perpendicular to one another. The method can include moving the mandrel along second and/or third directions together or separate from expanding the mandrel along the second and third directions. ## Claims ### Claim 1 A method for shaping the mouth of a hollow precursor made of glass, comprising: heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth, the first and second directions being perpendicular to one another. ### Claim 2 (depends on 1) The method of claim 1, further comprising: withdrawing the mandrel along the first direction from the mouth; and withdrawing the shaping rollers along the second direction from the outside of the mouth. ### Claim 3 (depends on 2) The method of claim 2, wherein the step of withdrawing the mandrel from the mouth occurs before or after the step of withdrawing the shaping rollers from the outside of the mouth. ### Claim 4 (depends on 1) The method of claim 1, further comprising moving the mandrel along a third direction, the first, second, and third directions being perpendicular to one another. ### Claim 5 (depends on 2) The method of claim 2, further comprising moving the mandrel along the second direction. ### Claim 6 (depends on 5) The method of claim 5, further comprising moving the mandrel along a third direction, the first, second, and third directions being perpendicular to one another. ### Claim 7 (depends on 2) The method of claim 2, further comprising expanding the mandrel along the second direction and a third direction while the hollow precursor is rotating with the mandrel in the mouth, the first, second, and third directions being perpendicular to one another. ### Claim 8 (depends on 7) The method of claim 7, wherein the step of expanding the mandrel comprises expanding the mandrel before or after the step of pressing the shaping rollers on the outside of the mouth. ### Claim 9 (depends on 8) The method of claim 8, further comprising retracting the mandrel along the second and third directions while the hollow precursor is rotating with the mandrel in the mouth. ### Claim 10 (depends on 9) The method of claim 9, wherein the step of retracting the mandrel along the second and third directions occurs before or after the step of withdrawing the shaping rollers from the outside of the mouth. ### Claim 11 (depends on 9) The method of claim 9, wherein the step of retracting the mandrel along the second and third directions occurs before or after the step of withdrawing the mandrel along the first direction from the mouth. ### Claim 12 A plurality of pharmaceutical glass vials, comprising: 10 to 1000 glass vials each having a mouth with an internal diameter and an external diameter, wherein the internal diameter of the mouth of each of the 10 to 1000 glass vials differing from a nominal internal diameter value by less than 0.20 mm, and/or wherein the external diameter of the mouth of each of the 10 to 1000 glass vials differing from a nominal external diameter value by less than 0.20 mm. ### Claim 13 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the nominal internal diameter value is 7 mm or 12.6 mm. ### Claim 14 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the nominal external diameter value is 13 mm or 20 mm. ### Claim 15 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the internal diameter of the mouth of all of the 10 to 1000 glass vials differ from the nominal internal diameter value by less than 0.1 mm. ### Claim 16 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the internal diameter of the mouth of all of the 10 to 1000 glass vials differ from the nominal internal diameter value by less than 0.05 mm. ### Claim 17 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the external diameter of the mouth of all of the 10 to 1000 glass vials differ from the nominal external diameter value by less than 0.1 mm. ### Claim 18 (depends on 12) The plurality of pharmaceutical glass vials of claim 12, wherein the external diameter of the mouth of all of the 10 to 1000 glass vials differ from the nominal external diameter value by less than 0.05 mm. ### Claim 19 A device for shaping a mouth of a hollow precursor made of glass, the device comprising: a mandrel configured for introduction into the mouth along a first direction; and a mounting having the mandrel disposed thereon, wherein the mounting has a base element, the mandrel being movable along a second direction in relation to the base element. ### Claim 20 (depends on 19) The device of claim 19, wherein the mandrel is movable along a third direction in relation to the base element.
