ABSTRACT:
A weighing apparatus includes a liquid container which is of a variable volume. An transparent press plate is fixed on the upper surface of the liquid container. The top surface of the press plate has weight indexing marks which are indicated in a vortex-like arrangement. The liquid container can be pressed by the press plate to discharge liquid from the liquid container. A transparent, thin hose has an open end communicated with the liquid container, and a closed end positioned just under the indexing marks of the press plate in such a manner that the closed end of the hose is self-wound in a vortex-like arrangement. When the press plate is not pressed, a portion of the hose is gripped by a holding mechanism to prevent the discharged liquid from flowing back into the liquid container. When the press plate is pressed, the hose is released from the holding mechanism thereby permitting the discharged liquid from the liquid container to flow along the hose to a visible position just under one of the indexing marks.
