These tinplate cans[2] are often used to package breath mints, throat lozenges, instant coffee, biscuits and holiday treats.
In Denmark, butter cookies in tins are produced and sold there, and are also exported to other countries.
[7] The lid, which sometimes is hinged to the body of the container, is often held in place when closed by friction.
In other cases, two protruding lugs can pass each other only when the lid and the rest of the box are deformed slightly: pressure from the user's hands is sufficient to produce this deformation, while the parts resist this somewhat, and are flexible enough to recover their normal shape when released.
For example, Yvette Dardenne in Belgium has amassed a collection of approximately 56,800 tin boxes over two decades.
