Abstract
A cylindrical side wall of a can body has embossed features therein. Tooling for the embossing of a can body include male and female tooling members. The male member has protuberances of various elevations that apply embossed features of various depths to the can body, rendering a can with multi-dimensional features.
Claims7
A method of embossing a cylindrical side wall of a can body, said side wall having a product side that defines the inside diameter of said can body and a consumer side opposite thereto, said method comprising:
- providing a first tooling member having a first cylindrical surface, said first cylindrical surface having an outside diameter that is slightly less than the inside diameter of said can body, said first cylindrical surface defining one or more recessed portions therein;
- providing a second tooling member having a second cylindrical surface, said second cylindrical surface defining one or more protuberances extending therefrom, said protuberances adapted to correspond with said recessed portions, such that each individual said protuberance has a corresponding recessed portion,
- inserting said first tooling member into the can body proximate said product side,
- engaging the consumer side of the can body with a said second tooling member,
- conveying the continuous side wall of the can body between the first and second tooling members by the synchronized rotation of said first and second tooling members with respect to each other, wherein the tooling members define a pinch point thereinbetween that embosses the cylindrical side wall of the can body between said recessed portions and said protuberances such that when said can body is received on the tooling member, one complete revolution of the tooling member conveys substantially the entire cylindrical side wall of the can body through the pinch point.
Tooling for the embossing of a cylindrical side wall of a can body, said side wall having a product side that defines the inside diameter of said can body and a consumer side opposite thereto, said tooling comprising:
- a first tooling member having a first cylindrical surface, said first cylindrical surface having an outside diameter that is slightly less than the inside diameter of said can body, said first cylindrical surface defining one or more recessed portions therein and adapted to be inserted into a can body;
- a second tooling member having a second cylindrical surface, said second cylindrical surface defining one or more protuberances which define an asymmetrical pattern extending therefrom and adapted to correspond with said recessed portions of the first tooling member, such that each individual protuberance has a corresponding recessed portion, wherein the first and second tooling members cooperate to emboss a can body that is conveyed between the tooling members such that one complete revolution of the tooling members is capable of embossing substantially the entire cylindrical side wall of the container.
