    摘要: A mixer is provided having two tines. These tines have a bulbous configuration and can be traversed between an outward biased position and a compressed inward position. The tines are bendable. When distal ends of the tines are pushed against an inner surface of the container, the tines criss cross so that the distal end portions of the tines rub or scrape the bottom surface of the container.
