Argentina

On October 27, 1942, Ana Bosi de Fallardi of Buenos Aires, Argentina, patented an improved liquid container with an integrated spout designed for clean and controlled pouring. Her design prevented liquid on the container’s top from flowing back inside and could accept a removable dispensing tube for easier use.

On September 5, 1946, Solveig Aida Bierregaard of Argentina patented an orthopedic insole designed to correct flat feet by restoring the foot’s natural arches. Shaped with opposing inclined planes that rotated the foot into anatomical alignment, it offered support at the natural weight-bearing points without creating pressure or discomfort.
