In present embodiment, as shown in figure 12, the minimum range between ontology 210 and doorframe 240 is second distance L2.This Minimum range between body 210 and end door 230 is first distance L1.Preferably, second distance L2 and first distance L1 be 2mm extremely 10mm.Doorframe 240 is contacted thereby, it is possible to avoid ontology 210 from deforming, and then damages the coating of doorframe 240, also can effectively be hidden Gear outside is dusted, and outside is avoided to dust into container.

It is further preferred that second distance L2 and/or first distance L1 is 3mm to 6mm.Thereby, it is possible to further avoid Ontology 210 deforms and contacts doorframe 240, and then damages the coating of doorframe 240, also can effectively block outside and dust, and avoids outer Side spray powder enters in container.

In present embodiment, as shown in figure 11, on the left and right directions of Figure 11, the surface towards end door of frame 260 and The 4th distance L4 >=20mm between the lateral surface of end door 130.Thus, it is possible to guarantee the quality of 230 surface electrostatic painting of end door, It is also beneficial to installation and removal spraying radical occlusion device simultaneously.

The other structures and first embodiment of present embodiment are roughly the same, and which is not described herein again.

The present invention also provides a kind of spraying methods of container.The spraying method passes through spraying radical occlusion device above-mentioned Spray container.Spraying method includes:

Spray container inner surface；

It is connected to end door by radical occlusion device is sprayed by interconnecting piece, the end door of container is closed, so that ontology is in crack between a door and its frame institute Vertical plane in projection be at least partially situated in crack between a door and its frame, wherein minimum range between ontology and end door be first away from From L1 > 0, the minimum range between ontology and doorframe is second distance L2 > 0；

Spray the outer surface of container.

The coating of baking-curing container.

In present embodiment, projection of the ontology in the vertical plane where crack between a door and its frame is at least partially situated in crack between a door and its frame, ontology Minimum range between end door is first distance L1 > 0, and the minimum range between ontology and doorframe is second distance L2 > 0, this Sample can reduce the width of crack between a door and its frame, can reduce dusting for spraying container outer surface and enter in container from crack between a door and its frame The coating of the inner surface of container is polluted in portion space, or is reduced dusting for container inner surface of spraying and flow to from crack between a door and its frame On the outside of container, to pollute the coating of the outer surface of container；Ontology does not contact doorframe and end door simultaneously, and doorframe is avoided to damage Coating on doorframe and end door.
