させる大きな原因となつていた。 As shown in Fig. 1, a conventional spray device of this type uses a nozzle so as to spray the spray onto the inclined surface b at the tip end of the spray body a at a spray angle α' of approximately 75 degrees and a spray width angle α1 ' of 90 degrees to 100 degrees. Although the hole C is provided, the sprayed paint distribution is a symmetrical distribution d with the largest value at the center, so when paint is sprayed onto the can body, it forms a drumhead pattern e, and even if these are stacked in a spiral shape, it will not be uniform. The coating thickness could not be obtained. On the other hand, because the spray angle of the paint is wide and it is easy to spray onto the bottom of the can, bridging and brisking of the paint occur at the boundary between the can body and the seam end, that is, the seam crevice, and the paint turns into water-based. This was a major cause of cans with poor coating.

内面塗装が可能となる。 The two spray bodies 1 and 2 advance a certain distance into the rotating two-piece or three-piece can 3 by an appropriate drive device and then stop, and at the same time water-based paint is sprayed from the first and second nozzle holes 6 and 10. Tighten the lid 4
Then, spraying is started on the can body 8, and one end spray main body 1 stops at that position and sprays the seam lid 4 continuously, so that the inner surface of the seam lid 4 is coated uniformly. On the other hand, the other body part spray body 2
is sprayed in a flat pattern shape 9 on the inner surface of the can body 8 while retreating at a constant speed.
Paint the inner surface evenly. Further, when the inner surface of the flange portion 13 of the can body 8 is completely coated, the spraying of the two spray bodies 1 and 2 is stopped, and the two spray bodies 1 and 2 are applied to the outside of the two-piece or three-piece can 3 as appropriate. retreat to position. This operation is performed sequentially.
By repeating this process, the inner surface of the 2-piece or 3-piece can 3 is continuously coated. By arranging a large number of such spray devices, it is possible to coat the inner surfaces of a large number of cans.
この発明のスプレイ装置は上記の構成よりなる
ので下記の特有な効果を奏する。 Since the spray device of the present invention has the above-described configuration, it has the following unique effects.
(イ) ボデイー部スプレイ本体の第二ノズル孔をフ
