Glass Container
Boston Round Bottle
The Boston round bottle (also called a Winchester bottle) is a cylindrical glass container with distinctive curved shoulders that taper to a narrow threaded neck. The rounded shoulder design prevents liquids and creams from collecting in hard-to-reach corners. Made from Type III soda-lime glass, these bottles accept a 28-400 continuous thread finish (on common sizes) that's compatible with caps, droppers, pumps, and sprayers.
Boston rounds are the workhorse of pharmaceutical, laboratory, and personal care packaging.
