I've had a plastic Kraft Parmesan Cheese shaker bottle that I've used for years. It's got the split opening on top (one side for shaking, one side for pouring) that I can lift and drop my rotary blades, rusted or bent pins, and machine needles in. When it's full I just duct-tape the top and throw it in the trash. A bottle usually lasts me 4-5 years.
