A full aperture beverage end has a center panel, a countersink surrounding the center panel, a main score arranged in proximity to the countersink to define a removable aperture panel and a vent score. The beverage end is adapted for use with products that are pressurized to over 30 psi (200 kPa) when opened, and during opening the vent score is adapted to sever first, controlling the pressure differential between the external surface and internal surface of the center panel, thereby allowing the main score to tear in a controlled and reliable manner.

The invention relates to a lid (10) consisting of metal, in particular of aluminum. For a beverage can or the like, which lid is designed to be permanently connected to a can body and has a lid panel (20) on which a rivet (40) for a grip tab (14) is formed and in which a predetermined breaking line (34) defining a breaking open area is impressed, along which line an opening in the lid panel (20) can be opened by means of the grip tab (14), wherein a rivet base (47), which has resulted from a formation of the rivet (40), is present around the rivet (40), within which base the metal of the lid (10) is thinner and or more brittle than in adjoining region of the lid panel (20). The particular feature of the invention consists in the fact that the predetermined breaking line (34) runs outside the rivet base, and a material-thinning embossment (44), which likewise runs outside the rivet base, is provided at least in a lid panel region which is situated between the rivet base (47) and a predetermined pressing point (48) of the breaking-open area onto which a breaking-open edge of the grip tab presses to open the drinking opening, wherein the predetermined breaking line (34) overlaps the material-thinning embossment in the lid panel region and the embossing depth of the predetermined breaking line is greater than the embossing depth of the material-thinning embossment (44).

An ecology stay-on tab beverage can end has a first axis extending though a rivet. A tear panel is defined by a frangible score and a non-frangible hinge that joins a first end of the frangible score with a second end of the frangible score. The first axis forms a line of asymmetry of the tear panel. A second axis intersects the first axis at a right angle. An intersection of the first axis with the second axis defines a center point of a clock-like reference having a 12 o'clock position at the first point and a 6 o'clock position at the second point. A first radius of curvature of the frangible score between a 5 o'clock position and a 7 o'clock position is at least 3.6 times larger than a second radius of curvature between a 7 o'clock position and a 9 o'clock position.

An end closure for food and beverage containers is provided. The end closure comprises a score fracture force reduction feature. Thus, less force is required by a user to fracture the score and open the opening in the end closure. In one embodiment, the score fracture force reduction feature is a collapsible form raised above the center panel and having a score line and a coined area.

A container closure includes a generally planar body having a product side and a customer side. The body includes a container opening. The container opening includes a shifted material line.

A tamper evident container comprises a lid and a base. The lid includes a lid rim having a lid rim flange. The base includes a base rim having a base rim flange. A frangible hinge is formed between a top pinch segment peripherally projecting from the lid rim flange and a bottom pinch segment peripherally projecting from the base rim flange. The frangible hinge is configured to rupture when the container is in the initially sealed arrangement by the application of a pinching force to the top pinch segment and bottom pinch segment that results in the relative vertical movement of the segments toward each other. As compared to the prior art, the container hinges about a frangible vertex instead of hinging about a square-shaped structure.

A can lid comprising: a main body comprising a laminate metal sheet, the laminate metal sheet comprising a metal sheet and a first resin film on a major surface of the metal sheet, the major surface having a score line delimiting an opening piece, the first resin film comprising a first resin layer comprising a dimer acid-copolymerized polyester resin and being amorphous; and a tab attached to the main body and adapted to cause a cleavage along the score line.

A container including a reservoir to store a dispensable material and an elongated neck that extends from the reservoir and that terminates at a distal end. The container also includes a frangible region intermediate the reservoir and the distal end of the elongated neck. The frangible region is fracturable in response to a predetermined force applied to the distal end to create opening in the elongated neck through which the material can be dispensed from the reservoir. The container further includes a guard disposed adjacent the elongated neck to inhibit inadvertent fracture of the frangible region absent the predetermined force.

A tamper evident container comprises a lid and a base. The lid includes a lid rim having a lid rim flange. The base includes a base rim having a base rim flange. A frangible hinge is formed between a top pinch segment peripherally projecting from the lid rim flange and a bottom pinch segment peripherally projecting from the base rim flange. The frangible hinge is configured to rupture when the container is in the initially sealed arrangement by the application of a pinching force to the top pinch segment and bottom pinch segment that results in the relative vertical movement of the segments toward each other. As compared to the prior art, the container hinges about a frangible vertex instead of hinging about a square-shaped structure.

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.
