Low expansion type excellent in heat resistance (thermal expansion coefficient alpha: 32-33 / ° C. × 10 -7 ), excellent in expansion type chemical durability (thermal expansion coefficient alpha: 48-56 / ° C. × 10 -7 ), high expansion type with excellent low-temperature workability (thermal expansion coefficient alpha: 60-70 / ° C. × 10 -7 ) and the like. Further, in the non-borosilicate glass, soda lime glass is used, this is high expansion type (thermal expansion coefficient alpha: 95 / ° C. × 10 -7 ) are included many things. The glass used for medical vials, Pharmacopoeia (USP37 or EP6.0) and ASTM, etc. JIS, have been described as the material standard pharmaceutical containers and laboratory instruments.
[0003]
　The heat resistance of glass containers, thermal expansion coefficient, breaking strength, as well as glass properties such as modulus of elasticity, shape and size of the container, the uniformity of the glass thickness and the like, surface conditions, the production conditions such as annealing conditions It is also dependent. Heat-resistant temperature of the glass as the physical properties that depend on these conditions (Delta] t) can be derived as a physical quantity based on the following formula (I).
Formula (I): Delta] t = P (1-sigma) / .alpha.E　
(Delta] t: heat-resistant temperature, P: breaking strength, sigma: Poisson's ratio, alpha:: thermal expansion coefficient, E modulus)
from the experimental results further Volf, less practical experience formula shown in (equation (II)) is derived.
Formula (II): Delta] t = 10000 / alpha × 10 -7

In this state, thermal flame 31 ejected from the tip of the point burner 30 is adjusted to be strong enough to carry out the fire blast. That is, thermal flame 31, it is necessary strength to the alkali components or the like contained in the processed degradation region can be removed to the outside of the vial 10. Flame 31 is ejected from the tip of the point burner 30 by being collide with the inner surface 15 of the vial 10, the processing deterioration area of ​​the inner surface 15 of the vial 10 is removed. Process machining deteriorated area is removed by impinging flame 31 ejected from the tip of the point burner 30 is referred to as fire blast.
[0083]
　Rotation of the above-described roller pair 60, because the vial 10 is rotated, the flame 31 is uniformly collide with the circumferential direction of the inner surface 15 of the vial 10. Furthermore, the slide device 42, point burner 30 is moved in the axial direction of the vial 10 (front-rear direction 103). With the movement of the point burner 30, the tip of the point burner 30 is scanned along the axial direction of the vial 10 (front-rear direction 103). For example, the tip of the point burner 30 is moved from the vicinity of the bottom 11 of the inner surface 15 of the vial 10 to the vicinity of the neck portion 18. With the movement of the tip of the point burner 30, the flame 31 ejected from the tip of the point burner 30 is scanned along the axial direction of the vial 10 (front-rear direction 103).
[0084]
　After fire blasting, thermal flame 31 ejected from the tip of the point burner 30 is adjusted weaker than thermal flame 31 ejected from the tip of the point burner 30 at the time of fire blast. The point burner moving device 40, point burner 30 is moved to the axis of the nozzle 32 in a state in which along a direction parallel to the axis of the vial 10.

[0085]
　As shown in FIG. 1, after the vial 10 is fire blasted by the roller pair moving device 95, the vial 10 roller pair 60 which is placed thereon, the position of the left side of the lateral direction 102 in fire blasting machine 80 (hereinafter , it is moved to also referred to as vial removal position P3.). In vial removal position P3, the vial 10 is removed from the outer peripheral surface of the roller pair 60 by the vial mobile device 94. Specifically, arm 91 is drawn downwardly, the arm 91 after the vial 10 has been adsorbed by the carrier part 92 by being retracted upwards, the vial 10 from the outer peripheral surface of the roller pair 60 is removed. Arm support 93 remains vial 10 is attracted to the support portion 92 is moved in the front-rear direction 103. By vial 10 is removed from the carrier part 92, the vial 10 to processing degradation region has been removed is obtained.
[0086]
　Following fire blast vial 10, the vial 10 by the vial changer 90 may be processed continuously separate vial 10.

New vial 10, in the same manner as described above, is moved to the fire blast position P2 fire blasting is performed, is being subsequently moved to the vial removal position P3 removed from the roller pair 60. By such an operation is repeated, fire blasting is repeated by placing while exchanging the vial 10 to the same roller pair 60.
[0087]
[Effects of the Embodiment]
　According to this embodiment, by the flame 31 to the inner surface 15 of the vial 10 is collision, the vial 10 is heated. By the flame 31 is impinged on the processed degradation region, the processing degradation region are removed. The outer peripheral surface of the vial 10 is in contact with the outer peripheral surface of the roller pair 60. Side portion 12 of the vial 10 is supported by the outer peripheral surface of the first roller 61 and second roller 62. While flame 31 to the inner surface 15 of the vial 10 is collision, first roller 61 and second roller 62 rotates, in each of the outer circumferential surface, in contact with the peripheral surface of the vial 10 to be rotated. Therefore, variations in the vertical direction 101 of the vial 10 is suppressed. Thus, a vial 10 of breakage or deformation is suppressed is produced.
[0088]
　In the above processing steps, while rotating the vial 10, the flame 31 ejected from the point burner 30 is scanned in the axial direction of the vial 10. Thus, the range of the flame 31 ejected from the point burner 30 impinges on vial 10 directly for extending axially, the processing deterioration area of ​​more extensive in the axial direction is eliminated.
[0089]
　Further, the entire outer peripheral surface having a maximum diameter in the vial 10 is brought into contact with each outer peripheral surface of the first roller 61 and second roller 62. Thus, the entire outer peripheral surface of the side portion 12 of the vial 10, into contact with each outer peripheral surface of the first roller 61 and second roller 62. From the whole side portion 12 definitive outer peripheral surface of the vial 10 to the first roller 61 and second roller 62, the heat of the vial 10 is conducted. Therefore, by the side portion 12 of the whole definitive outer peripheral surface heat of the vial 10 is uniformly dissipated, the deformation of the side portion 12 of the vial 10 is further suppressed.
[0090]
　The first roller 61 and second roller 62, so that the surface which faces the point burner 30 is above the opposite side, the axis of the first roller 61 and second roller 62 is inclined with respect to the horizontal direction ing. Thus, the vial 10 supported by the outer circumferential surface of the first roller 61 and second roller 62, in the manner the outer peripheral surface of the vial 10 to the outer peripheral surfaces of both the first roller 61 and second roller 62 is in contact since the vial 10 is placed on the first roller 61 and second roller 62, the opening of the vial 10 is supported so as to face upward from the horizontal direction. Therefore, without the vial 10 is moved in the horizontal direction is maintained in a stable position.
[0091]
　Also, to remove the machining deteriorated region, the flame 31 is blown to the inner surface 15 of the vial 10. Accordingly, the vials 10 moving force in the axial direction to the bottom 13 side is applied. The bottom of the vial 10 13 abuts the abutting member 20. Therefore, the abutting member 20 regulates the moving to the bottom 13 side and the vial 10 in the axial direction.
[0092]
　Further, the heat given to the vial 10, in contact with the vial 10 and the roller pair 60 (the region along each axial direction of each of the outer peripheral surface), transmitted to the roller pair 60. Similarly the bottom 13 of the vial 10 is in contact with the contact member 20. Heat applied to the vial 10, in contact with the vial 10 and the abutting member 20 (region), transmitted to the abutting member 20. Roller pair 60 and the abutment member 20, to include at least a member constituting the respective outer peripheral surfaces or the abutting member 20 of the roller pair 60 having a high heat dissipation property of stainless (for example, graphite.), A stainless steel high dissipation of heat in comparison. Therefore, the heat transmitted to the roller pair 60 and the abutting member 20 is easily dissipated in comparison with stainless steel, it is dissipated quickly. Moreover, even with the fire blast continuously roller pair 60 and the abutting member 20 more than once, it is suppressed that heat roller pair 60 and the abutment member 20 becomes too high temperatures than are accumulated stainless that. Therefore, a plurality of vials 10 good quality breakage or deformation is suppressed is continuously produced.
[0093]
　The length in the axial direction of the first roller 61 and second roller 62 is longer than the length in the entire axial direction of the outer peripheral surface having a maximum diameter in the vial 10. Thus, the entire outer peripheral surface having a maximum diameter of the vial 10, into contact with each outer peripheral surface of the first roller 61 and second roller 62. Since the entire outer peripheral surface of the heat of the vial 10 is uniformly dissipated, the deformation of the side portion 12 of the vial 10 is further suppressed.
[0094]
　Further, since the adjustable rotational speed of the roller pair 60, the inner surface of the vial 10 in fire blast process, the temperature difference between the temperature and other parts of the location where the flame 31 ejected from the point burner 30 is in contact with the , it falls within the desired range.
[0095]
[Modification]
　In the present embodiment, the container forming process, although the vial 10 with a common vertical molding machine is molded, other molding methods may be employed. For example, molding the glass container from a glass tube held in a state in which along the axis of the glass tube in a horizontal direction vial 10 may be formed by (so-called using the horizontal molding machine).
[0096]
　The glass container is not limited to the vial 10 may be a glass container of another shape. For example, it may be a glass ampoules shape intermediate product vial 10 is not fully formed, for example, the bottom portion 11 is shaped mouth 13 may be one which has not been molded.
[0097]
　The roller pair 60 is not limited to a pair, or may be a plurality of roller pairs 60. For example, by using a plurality of roller pairs 60 simultaneously, may be fire blasted plurality of vials 10 simultaneously. In that case, a plurality of roller pairs 60, the axes of all the rollers are provided on the roller pair moving device 95 as parallel. Multiple points burner 30 is provided corresponding to each pair of rollers 60 or adjacent roller pairs 60,.
[0098]
　The roller pair 60 is not limited to a cylindrical shape, it may have a shape along the outer peripheral surface of the vial 10. For example, the neck portion 18 as well as side portions 12, by the shape along a peripheral surface of each portion of the vial 10, such as a mouth 13, all portions of the outer peripheral surface of the vial 10, first roller 61 and the to contact with each outer peripheral surface of the second roller 62, damage or deformation of the side portion of the vial 10 is further suppressed.
[0099]
　Although the chain 98 is used to rotate the roller pairs 60, engaging with the pinion gear on each roller shaft pinion gear 69 is provided, even when the roller pair 60 is rotated by rotating these pinion gears good.
[0100]
　The roller pair 60, such that the surface facing the point burner 30 is above the opposite side, but the axis of the roller pair 60 is inclined to the horizontal direction (front-rear direction 103), the roller pair 60 the axis of the roller pair 60 may be positioned such that the horizontal direction (front-rear direction 103). Accordingly, the nozzle 32 points burner 30, by the axis of the point burner 30 is moved in the horizontal direction (front-rear direction 103) in a fixed state such that the horizontal direction (front-rear direction 103), the vial in the inner space 14 of the 10 may be inserted.
[0101]
　Further, the flame 31 ejected from the tip of the point burner 30 in order to collide with the machining deteriorated area on the inner surface 15 of the vial 10, by the point burner moving device 40, the nozzle 32 points burner 30, the axial direction is the horizontal direction by point burner 30 to tilt it is rotated, which remain fixed point burner 30, the vial 10, the axial direction is further inclined relative to the horizontal direction with respect to the point burner 30 flame 31 ejected from the tip of the may be the collision in the processing deteriorated area on the inner surface 15 of the vial 10.
[0102]
　In the third step, the inner surface 15 of the vial 10 impinging flame 31 ejected from the tip of the point burner 30 is not necessarily the entire inner surface 15. For example, if the machining deteriorated area exists only in the vicinity of the bottom 11 of the inner surface 15 of the vial 10 may collide flame 31 only near the bottom 11 of the inner surface 15.
[0103]
　Also, the vial changer 90 has been moved by adsorbing the vial 10 to the support section 92 by vacuum, by using such arms so as to grip the vial 10 may be a vial 10 is replaced.　　　　　　　　　　　　　　　　
[0104]
　The shape of the abutting member 20 is not limited to a flat plate may be a flat plate with the bottom 11 of the vial 10 abutting shape, for example circular, may be of any shape, such as triangular or trapezoidal .
[0105]
　Moreover, the abutting member 20 is not the entire contact member 20 is limited to what is configured in what is high heat dissipation property of stainless, only the bottom 11 and the abutting portion of the vial 10, the heat dissipation property of stainless it may be high.
