Abstract
Electronic weighing apparatus (3) is provided including a transparent cylindrical cover member (13) defining a weighing chamber (1) within which the load weighing pan is contained. The cover member contains an access opening (16) and is rotatable about its axis relative to a concave housing wall portion within which it partially concentrically extends. The cover member is rotatable relative to the housing between closed and open positions in which the access opening is contained within and remote from the concave wall portion, respectively. A radially displaceable member (25) is biased by a spring (29) to close the access opening in a tightly sealed manner when the cylindrical cover member is in the closed position.
