Abstract: A packaging container for a liquid and more specifically for coffee milk has a container proper having a bottom opening and a bottom cap to seal the bottom opening of the container proper after the container is filled. The container proper having a sectional shape suitable for stacking containers in each other, a top plane having a planar dimension and shape suitable for supporting the container stably when it is turned upside down and being provided with a pouring opening having a lid with hinge action given by a light-gage hinge portion formed at one end of the lid. The lid having a vertical flange at the inside face, whose lower end is connected integrally with a peripheral edge of the pouring opening with an easily broken light-gage portion formed therebetween.

Abstract: A method of multiple powder coating wherein articles to be coated are fed to a conveyor which comprises a pair of Geneva gears secured to both ends of a rotatable shaft. The Geneva gears have a plurality of channels around the periphery thereof for holding the articles. The gears are rotated intermittently at an interval of one channel and an article to be coated is fed to a pair of channels at every Y intermittent rotations, where Y is the number of coatings to be applied. The article is coated once in each cycle of rotation of the Geneva gears and is removed following X times Y intermittent rotations, where X is the number of channels around the periphery of each gear. X is odd when Y is even and X/Y is a decimal when Y is odd.
