A receiver for urine whether for taking sample or disposing thereof, includes an open-top of saddle shape which approximates the configuration of thighs, labia or other convenient zone. The receiver may be connectable to a sample container by a bayonet joint. The bayonet joint may have one or more protrusions located about an outer circumference of the lower end of the receiver and a channel formed proximal to the upper end of the sample container, the channel having one or more transverse grooves.
