局部区域被覆方法和被覆装置
摘要：
在杯状纸成型体(1)的贴合台阶部等局部喷镀粉体树脂而形成树脂隆起(8、9)，从而提高纸成型体的密封性，并且，在微波炉加热时容易发生烧焦的局部区域形成含有防止烧焦物质的树脂被覆层(60)。局部区域处的树脂隆起是通过遮挡装置从罐体中间歇性地切出树脂粉体，并利用加压气体反复喷镀到局部区域而形成的。
摘要（英）：

A raised resin portion 8, 9 is formed by thermally spraying a powdered resin on a local portion such as a bonding step portion of a cup-shaped formed paper article 1 to improve sealing performance ofthe formed paper article and form a resin coating layer 60 including a scorching-preventing substance on a local region where scorching tends to occur during heating in a microwave oven. The raised resin portion is formed on the local region by intermittently discharging the resin powder from a tank with a shutter device and repeatedly thermally spraying the resin powder on the local region with apressurized gas.
