Abstract

A flat can of a size which will fit in a person's pocket which is suited particularly for snuff, but is adapted for use with other products. The can has a bottom wall and a cylindrical side wall, and there is a lid with a top wall and a downwardly-extending peripheral flange which fits snugly around the neck of the cylindrical side wall. The lid is held in place by circumferential rib structures, respectively on the outer surface of the neck of the side wall and on the inner surface of the lid flange. There are also vertical ribs on the can neck which extend upwardly from the peripheral rib and which provide venting when the lid is installed. The vertical ribs are in pairs spaced a short distance from each other and there is a gap in the peripheral rib on the neck between the bottom ends of each pair of vertical ribs. When the lid is being installed or removed, the circumferential rib on the lid flange rides upon the vertical ribs so as to facilitate the movement of the lid flange on the neck. The rib structure on the lid flange is also formed by spaced segments with gaps between their ends. The arrangement is such that a plurality of vertical vent passageways between the respective pairs of vertical ribs are in alignment with gaps in the circumferential rib construction on the lid flange. Hence, when the lid is in place, the can is still vented, and the product in the can is properly vented when that is desirable. However, when the product in the can must be sealed, a circumferential label or wrapper of impervious material is placed on the can after the lid has been put into place.
