A transfer roller (18) is rotatably arranged at a position corresponding to. The transfer roller (18) is formed by fitting a rubber body (22) onto the outer peripheral surface of a disc body (20). The transfer roller (18) comes into contact with the male screw portion (4) formed on the neck portion (3) of the screw cap glass bottle (1). In addition, the transfer roller (1
A disk-shaped vitreous liquor receiving roller (26) is disposed in 8) so as to abut. A straw member (28) for flowing the low-melting glass liquid through the glass liquid receiving roller (26).
Is provided. Also, a glass liquid receiving roller (26)
The liquid amount adjusting plate (3
0) is provided with a tip part (32), and when a large amount of low-melting glass liquid flows from the straw member (28) to the glass receiving roller (26), the liquid amount of excess low-melting glass liquid is adjusted. The tip (32) of the plate (30) is adapted to be removed.

（６）の歪みが取り除かれる。Next, the operation of the embodiment will be described. The screw cap glass bottle (1) manufactured by a process not shown is horizontally moved by a conveyor chain to a position corresponding to the receiving rollers (12) and (12).
At this time, the receiving rollers (12), (12) move upward from below (in the direction of arrow A) to hold the screw cap glass bottle (1) and move it upward. For this reason,
The body part (6) of the screw cap glass bottle (1) has a receiving roller (1
2) and (12) and the rotary roller (16). Further, the screw cap glass bottle (1) is rotated by the rotation of the rotating roller (16). Meanwhile, the transfer roller (1
8) contacts with the male screw portion (4) formed on the neck portion (3) of the screw mouth glass bottle (1), so that the low-melting vitreous liquid flowing from the straw member (28) receives the vitreous liquid receiving roller (2).
6), it is applied to the male screw part (4) via the transfer roller (18). When the low-melting glass liquid flows excessively, the tip portion (3) of the liquid volume adjusting plate (30) is
Since the excess is removed by 2), an appropriate amount of low-melting glass liquid is applied to the male screw part (4). Therefore, the low-melting glass liquid is applied uniformly on the male screw portion (4) without causing unevenness in the applied amount. Then, when the application of the low-melting glass liquid to the male screw portion (4) of the neck portion (3) is completed, the receiving roller (12) moves downward (direction of arrow B),
The screw cap glass bottle (1) is released from the holding roller (12) and the rotating roller (16). Next, the screw cap glass bottle (1) is housed in a tunnel furnace (not shown) by a conveyor chain. And about 7 in this tunnel furnace
It is heated to 00 degrees. For this reason, the low-melting glass liquid applied to the male screw portion (4) of the screw cap glass vial (1) is sintered to form irregularities (5) on the male screw portion (4). Moreover,
Since the unevenness (5) is formed by sintering low-melting glass liquid, crushed powder or the like does not adhere to the unevenness (5), so that cleaning is not necessary. Further, the heating removes the distortion of the main body portion (6) of the screw cap glass bottle (1).

を塗布するようにしてもよいことは勿論である。In this embodiment, the low-melting glass liquid is applied to the male screw portion (4) of the screw cap glass bottle (1) by a mechanical process, but the present invention is not limited to this. Of course, the low-melting glass liquid may be applied to the male screw portion (4) of the mouth glass bottle (1).
