A can lid that comprises an opening region provided in the material of the lid surface and comprises a two-armed lever member that is intended to open this opening region and that is connected to the lid material, wherein this arrangement is characterized in that the opening region configured as a tongue tab is delineated from the lid surface by a tear line and the tongue tab base connected to the lid surface forms a pivot bearing that becomes effective during the opening procedure; in that the lower side of the lid is coated with a plastic material in a firmly adhering manner, and this coating of the tear line that covers the tear line is weakened in an adjacent manner; and in that the container part and the can lid at least substantially comprise the same aluminum alloy.

A tear open container as shown and described herein. The tear open container may include a plurality of panels including a rear, left, front, right, top, bottom and include a dieline including perforations to allow a user to separate the container into a top portion and a bottom portion. The remaining bottom portion may be configured to store and display articles, such as binders, on a shelf. The top portion may be discarded. A tab and pull flap may be defined by the dieline and allow the user to easily remove the top portion from the bottom portion. The user may depress the tab to grasp the pull flap and perforate the remaining portions along the dieline.

A first score line (430) is curled inward at one end section (431) and the other end section (432) of the first score line (430) so as to go into a region enclosed by the first score line (430), and the first score line (430) approaches a center line (CL) of a tab as going to the trailing ends thereof. In addition, a curvature at which the first scored line (430) is brought closer to the other end section (432) side is applied to the one end section (431) of the first score line (430), and a curvature at which the first score line (430) is brought closer to the one end section (431) side is also applied to the other end section (432) of the first score line (430).

A metal end for seaming onto a metal container body. The end comprises an outer curl, a centre panel within the outer curl, and a tab having a longitudinal axis (A). The end further comprises a rivet securing the tab to the centre panel, and a score in the centre panel having two spaced apart ends which define a hinge therebetween, the hinge lying on one side of said longitudinal axis (A), such that operation of the tab fractures the score and causes the region of the centre panel within the score to pivot about the hinge and provide an aperture in the centre panel. The score extends into a region of the centre panel that is behind a centre line (B) running through the centre of the rivet and perpendicular to said longitudinal axis (A), and on the other side of the longitudinal axis (A) from the hinge.

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.

An end closure for food and beverage containers provides controlled opening characteristics to prevent the unintentional missiling of a tear panel. The end closure comprises a score line that defines a portion of the tear panel, and the end closure may comprise one or more anti-missile features that inhibit the propagation of a fracture down a score line, which reduces the likelihood that a tear panel will inadvertently detach from the end closure and injure the user or another.

A metallic can end having a reclosable opening has a microgap or a weakening line peripherally around the opening, a sealing frame composed of plastic material surrounding the opening region, a closure unit composed of plastic that is disposed within the microgap or weakening line and that is pivotably attached to the fixed end surface via a pivot bearing. The sealing frame and the closure unit cooperate in a sealing manner. The metallic end region disposed within the peripheral microgap or the weakening line is received and held in the opening region of the end. The sealing frame is bonded to the fixed end surface and the closure unit is bonded to the upwardly pivotable metallic end region. Except for a possibly provided lacquer layer, the inner end side is at least largely free of lamination and the like.

A container, in the form of a container body or container closure, or a lid, having a frangible weakened portion formed in a layer of polyethylene terephthalate forming a wall of the container, the weakened portion comprising a groove cut into a first surface of the layer, a first portion of the layer surrounding the groove having a crystallinity of from 35 to 45%, and a second portion of the layer, which second portion is adjacent to the first portion on opposite sides of the groove and remote from the groove, the second portion having a crystallinity at least 5% less than the crystallinity in the first portion, wherein the layer has a thickness of from 200 to 700 m and the groove has a depth of from 200 to 500 m.

The present invention relates to a container end closure that generally comprises a pour opening and a secondary vent opening which improves venting during emptying of contents from the container. In particular, the present invention relates to an end closure for a container having scores defining a secondary vent opening which may optionally be opened. The secondary vent opening has a significantly larger area then vents of prior art designs and thereby improves pour rate and smoothness of pour. After the pour opening is opened using a pull tab interconnected to the end closure, a consumer may selectively open the secondary vent opening by pulling back on the tab.

A can lid is described that is in particular intended for beverage cans and that differs from the generally known metallic can lids in that the opening region is configured as a tongue tab that is separated from the lid surface by a microgap, in particular a punched gap, extending over the tab periphery and the tongue tab base connected to the lid surface forms a kink bearing that becomes effective on the opening procedure and that is connected to the lid surface, and in that the lower side of the metallic lid is in particular coated over its whole surface in a firmly adhering manner with a plastic material, in particular a plastic film, and this coating is weakened, in particular notched, adjacent to the microgap between the tongue tab and the lid surface.
