摘要

One of the walls of the container accommodates a window, which extends either vertically or obliquely over part or the entire portion of the wall. The window is provided with at least one marker and is sufficiently translucent to permit visualisation of the filling liq. The markers may be used to indicate the calorific value of partic. food substance. The container is formed of an opaque plastics envelope soldered along its lateral and upper edges. The window is formed along the lateral edge at one of the envelope walls. In manufacture, a food substance to be diluted extemporaneously is introduced into the envelope and the remaining unsoldered edge is soldered. During use, the upper edge of the envelope is cut for emptying into a recipient.
