The B614BK is a 190 cc black HDPE plastic oblong pill packer bottle with 38-400 neck finish. This container is an oblong pill packer bottle. This means that it is essentially rectangular in shape, as opposed to the traditional round. Packers come in a variety of sizes, but they are typically "squatty" in shape with a wider mouth. Packers are used extensively for pills, capsules, supplements, powders, and other health-related products. High density polyethylene (HDPE) is marked with the resin identification code of 2. HDPE has a high tensile strength, good resistance to chemicals, good impact resistance, highly rigid, and highly scratch resistant. This item has a 38-400 neck finish. The first number refers to the diameter (in mm), and the second refers to the closure depth, style and thread. This container can be paired with a closure with a matching finish.
