A coating method includes a first step for spraying, onto an inner area of an opening part of a cylindrical body having a bottom and arranged horizontally, a first coating material of synthetic resin containing non-volatile components while rotating the cylindrical body around a central axis thereof. After the first step, a second step is performed for spraying, onto an inner area of a barrel part of the cylindrical body, a second coating material of synthetic resin containing a lower proportion of non-volatile components than that of the first coating material while continuing to rotate the cylindrical body. After the second step is performed and before the volatile components of the second coating material vaporizes, a third step is performed in which the rotation of the cylindrical body is stopped, the cylindrical body is placed vertically, and the volatile components of the second coating material are vaporized.

Can inner surface coating method

Provided is a can inner surface-coating apparatus with which inspection of bottomed cylinders can be favorably performed in parallel without being affected by the coating process. In the can inner surface-coating apparatus, inspection cameras to be used for inspection following coating of the inner surface of a bottomed cylinder that will become the body of a can or bottle-shaped can are disposed above spray devices that are used for coating the inner surface of bottomed cylinders. Moreover, the coating area including the spray devices and the inspection area including the inspection cameras are covered with a cover. By supplying air inside the cover from the upper part (air supply port) of the inspection area and discharging the air out of the cover from the lower part (coating mist collection duct) of the coating area, an air flow is formed from the upper part of the inspection area to the lower part of the coating area.
