Abstract: A lid construction for a pressurized beverage container. The lid has a pouring opening which is normally closed by a generally pointed tab that is integrally connected to the lid by a hinge section. The peripheral edge of the tab underlies the edge of the lid bordering the opening, and a strip of sealing material is applied to the underside of the lid and seals the joint between the tab and the lid. The sealing strip can be provided with a weakened zone or line located in spaced relation to the joint. To open the container, the consumer presses downwardly on the tab and the pointed tip of the tab will rupture the sealing strip and continued downward force will move the tab to the open position to expose the contents of the container.

Abstract: A spin flanging machine for flanging the open end of container bodies, such as metal cans. The machine includes a drive shaft mounted for rotation on a supporting structure and a rotary turret is secured to the shaft and carries a series of flanging heads. Each head is provided with a plurality of flanging rollers which are adapted to engage the open end of the can. As the turret rotates, each head is rotated about its axis by the driving engagement of a pinion connected to the head shaft with a large fixed gear mounted on the supporting structure. The flanging heads are moved in a reciprocating manner towards and away from the can by a cam mechanism including a cam follower that is secured to the end of each head and engages a cam groove on the fixed supporting structure.
