Crown cork

 

The crown cork was the first highly successful disposable product^{[citation needed]} (it can be resealed, but not easily). This inspired King C. Gillette to invent the disposable razor when he was a salesman for the Crown Cork company. The firm still survives, producing many forms of packaging.^[1]

Prior to the invention of the external crown cork bottle stopper, soda bottles had ordinary internal cork bottle stoppers and often had rounded bottoms so they could not be stored standing upright. Corks have a tendency to dry out and shrink, allowing the gas pressure in the bottle to cause the cork to "pop", so bottles were stored on their side to prevents the corks from drying out. After the invention of the crown cork bottle stopper, this problem was eliminated, and soda bottles could be stored standing upright.^[2]

Crown corks are collected by people around the world who admire the variety of designs and relative ease of storage.^[3][4] Collectors tend to prefer the term "crown cap" over "cork".^{[citation needed]}
