  • Easy opening end unit with tapered score
    Patent number: 4320850
    Abstract: In an easy opening end unit for beverage and like liquid containers wherein the opening tab and displaceable panel portion are non-detachable and the displaceable panel portion is pushed into the interior of the associated can, if the required opening force is not maintained constantly uniform, then there is a tendency for a very rapid movement of the opening tab so as to cause the inwardly displaced panel portion to slap the liquid and to agitate the same, frequently to the extent that part of the liquid is splashed out through the newly formed dispensing opening. The opening force can be made more uniform by varying the score residual.
