ABSTRACT:
A can is formed by an overall cylindrical body with a nailed bottom wall and presenting on its superior part and close to an aperture thereof a round fillet which is outwardly turned. The closure of the can is by a metallic, easy-opening lid, formed essentially by a circular panel with a short descending skirt which is provided with a narrow peripheral fillet. The lid includes a sealing gasket on its internal surface and presenting, in the middle of its panel, a circular basin-shaped depression with a central hollow which is closed by a resinous, thermoplastic, detachable seal. The present improvements provide a new configuration for the superior part of the can body, by which the referred skirt of the lid and its respective fillet are inwardly spaced in relation to the side wall of the cylindrical body of the can, in such a way to eliminate any possibility of mounting or overlapping of the peripheral fillets of adjacent cans, whenever the cans are grouped or placed side by side.
