Abstract
Abstract A packaged food article for constitution with water (or other aqueous potable liquid) is provided in the form of a perforated hard shell gelatin capsule containing a predetermined quantity of a soluble food extract. The capsule wall is perforated at a number of points spaced over the middle and both ends of the capsule so that, when a serving of hot water is agitated with the capsule, contact of the article with water is extensive whereby both the container and the contents promptly dissolve to provide refreshment for immediate consumption.
