US Patent 7998126 Integral urine collector

A urine collector for females that use a frustropyramidal funnel member with a narrow end that has a rhombus-shape cross-section that a user can deform to fit a cooperating locking assembly with a frustropyramidal through aperture. As the deforming pressure on the folds of the funnel member is released, the outer walls of the narrow end of the funnel engage the internal walls of a frustropyramidal central through aperture in the locking assembly keeping the funnel member in place. The locking assembly can be integrally built in the collecting container or in a separate closure locking assembly.
