Glass milk bottle

Glass milk bottles are glass bottles used for milk. They are reusable and returnable – used mainly for doorstep delivery of fresh milk by milkmen. Once customers have finished the milk, empty bottles are expected to be rinsed and left on the doorstep for collection, or rinsed bottles may be returned to a participating retail store. Bottle sizes vary depending on region, but common sizes include pint, quart or litre.

More recently, plastic bottles have been commonly used for milk. These are often made of high-density polyethylene (HDPE) which is intended for a single use and is easily recyclable.^[1] Other plastic milk containers are also in use.
