RESEALABLE CAN END WITH STAY ON TAB
A reclosable beverage can end (10) has a circumferential curl (14) centered about a center longitudinal axis (50). A circumferential wall (15) extends downwardly from the curl (14) and inwardly towards the longitudinal axis (50). A center panel (12) is produced from a metallic material and centered about the longitudinal axis (50). The center panel (12) has a public side (34) and an opposing product side (35). A tab (26) is mounted to the public side (34) of the center panel (12). A pour opening (20) is formed by an aperture in the center panel (12) and sealed by the tab (26). The pour opening (20) is at least partially defined by a pour opening curl (22) of the metallic material of the center panel (12).
Reclosable lid for a food or beverage container and having a vacuum or pressure release button
A sheet metal lid has a rim portion removably secured and sealed to a container and the lid includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. The flange portion of the button has a short arcuate score or shear line extending substantially into the sheet metal, and additional score lines extend into the flange portion at lesser depths to protect a coating on the inner surface of the lid. A resilient sealant material may be bonded to the inner surface of the vent button, and the opposing sheet metal portions of the score line form a small gap for releasing a vacuum or pressure from the container in response to a controlled downward pressure on the top wall portion of the vent button.
Method and device for producing tear-off lids and tear-off lid
A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced economically and with the possibility for production at a high rate.
