ABSTRACT:
The weighing pan comprises a pair of opposed sidewalls and at least one pivotable closure flap which is coupled to one sidewall in such a way that the pivoting movement of the closure flap between closed and open position is accompanied by a displacement of the associated sidewall relative to the opposite sidewall. Articles, which might have got jammed between the sidewalls, are likely to be released in response to the relative movement of the sidewalls and drop out through the open bottom of the pan. A combination weighing machine including a plurality of weighing pans and means for reopening a pan, if necessary in order to ensure complete emptying thereof, is also disclosed.
