Abstract: A special bottle lid renders ubiquitous pill bottles into safe, effective, low cost sharps containers. For example, a common plastic bottle, such as one that holds 120 capsules, each sized for 1 gram of material, is conveniently sized to make a sharps container suitable for holding needles (detached from syringes) and blood test lancets used by diabetics. As a current bottle becomes filled, the special lid is moved to a second bottle, and the lid from the second bottle is used to seal the first bottle for disposal. This repeats as each new bottle is filled. Thus, the primary investment is the special lid, which may be reused with new empty bottles indefinitely. Example bottle dimensions range from 2.5 to 3 inches in diameter and 4.5 to 5.5 inches in height. Syringes without the needles (and thus safer) may be placed in a different, larger container.
