Cone top

A cone top (also called a cap-sealed can, cone-top, or conetop) is a type of can, especially a type of beverage can, introduced in 1935.

[1] Cone tops were designed in response to flat top beer cans as a hybrid between beer bottle and flat top can.

Cone tops were especially attractive to smaller breweries which did not have the capital necessary to buy new canning machinery; cone tops could be filled on standard bottling equipment.

Because they were typically made with steel,[2] beverage cans faded out during the metal shortages of World War II.

[3] They are now considered collector's items.
