I thought I'd ask here if anyone has any information or specifications for a typical Butterfly hinge. I'm looking for any patents, design drawings, or contacts in the industry that can help me in designing this style hinge. This hinge can be seen on may plastic hinged parts such as flip top caps on Shampoos or lotion bottles or other cosmetic containers. Any info would be greatly appreciated. Thanks.
