If the bag is hand sized and the container can be filled with all the weight, you could pinch and put the top half of the bag, turn the bag on a 45 degree angle on the mouth container, turn the bag 90 degrees (+ 45 degrees) to start filling the container. If the container can handle the fuller weight, and another 90 degrees to let the rest of the spice out. The container sits down as it is being filled by one hand. Do this in the sink, so left over spices can be easily washed away - water, soap and scrub and water. No funnel need.
