Structure of Metal Containers

Our can anatomy page will guide you through the standard tin can and lid components so you are able to select the container best suited for your needs.

Slip Cover
- Cover / Closure style in which the covers skirt (vertical surface slips over and to the outside of the can body).
Dome Cover
- A type of cover characterized by a flat horizontal surface (top) that tapers smoothly onto the skirt.(Vertical Surface)
Skirt
- The vertical surface between the edge of the top of the slip cover and the curl at the bottom of the slip cover.
Curl
- An area of tin turned in on itself to provide a safe, finished curved edge.
Bead
- Concave ( interior bead ) or convex ( exterior bead ) area usually 1/8" wide spanning the circumference of the tin to provide additional strength and stability to the tin body.

Embossed
- Type of slipcover in which a "step" is created between the horizontal surface and vertical surface of the cover so that stacking tins is possible with less likelihood of toppling over.
Debossed
- Type of slipcover that has a depression between the horizontal surface of the cover.
Plug
- The top that fits into the walls of the friction ring.
Multiple Friction Ring
- A plug closure fits into a "well" of a seamed ring. The plug is pressed into the ring and the two surfaces ( the outside and inside edge ) come into contact with the ring, creating multiple sealing surfaces on the plug/ring combination.
