Production of glass bottle packaging

Modern cosmetic bottles, when molded, will be given marks on the heel (bottom) of the bottle. These marks serve a variety of purposes, such as identifying the machine used in the production of the bottle (for quality control purposes), showing the manufacturer of the bottle, how much to fill the bottle to, the date the bottle was manufactured, as well as other information. Embossing on a bottle consists of raised lettering, numbers, and/or designs which were intended to inform the purchaser in some way of the contents or to establish ownership of the bottle

Glass bottles have a variety of closures to seal up the bottle and prevent the contents escape. Early bottles were sealed with wax, and later stoppered with a cork. More common today are screw caps and stoppers.
