Abstract

A can has a flange extending inwardly from a vertical wall and with a downwardly extending skirt wall defining an opening, a lower section of the skirt wall having continuously curved to form a first rib of open tubular shape of a substantial part of a circle around a lower end of the flange skirt wall. There is a lid for fitting into and sealing the can opening, the lid having a peripheral wall therearound with an end of an upper section having a second rib to engage a top of the can flange, a central wall portion below the second rib to oppose the flange downwardly extending skirt wall above the can first rib, and a recess around the lid peripheral wall below the central wall portion of a substantially V-shape with diverging walls. The can tubular first rib fits into the lid recess to engage at points along lines tangent tc the first rib extending around the circumference of the first rib with the points of engagement of the first rib with the diverging walls of the recess forming a lock between the lid and can flange and to seal the contents in the can from entering between the opposing lid central wall portion and flange skirt wall.
