Abstract
A can end for a container has a metallic main portion and a polymeric separable cap. The metallic main portion is positioned about a longitudinal axis and has a curl defining a radially outer perimeter of the can end. A center panel is joined to the curl. A dispensing aperture is in the center panel, and a plurality of projections extend radially inwardly into the dispensing aperture. The polymeric separable cap is in the dispensing aperture and has a plurality of angled channels. The channels have an entry portion opposite a terminal end and a vent region therebetween.
Claims20
A can end for a container, the can end comprising:
- a metallic main portion positioned about a longitudinal axis comprising a curl defining a radially outer perimeter of the can end, a center panel joined to said curl, a dispensing aperture in said center panel, a plurality of projections extending radially inwardly into said dispensing aperture, and a second curl in said center panel defining a peripheral edge of said aperture;
- and
- a polymeric separable cap in said dispensing aperture comprising a plurality of angled channels, the channels comprising an entry portion opposite a terminal end and a vent region therebetween comprising a vent stop in said vent region wherein a width of said channels in said terminal end is less than a width of said channels at said vent stop, the polymeric cap further comprising a flange extending radially outwardly beyond a perimeter of said aperture, an arcuate lower wall extending downwardly relative to a lower surface of said separable cap, said arcuate lower wall located radially inwardly from said flange and at least partially located within said aperture, said flange in engagement with said second curl.
A can end for a container, the can end comprising:
- a metallic main portion positioned about a longitudinal axis comprising a curl defining a radially outer perimeter of the can end, a center panel joined to said curl, a dispensing aperture in said center panel, and a plurality of projections extending radially inwardly into said dispensing aperture;
- a polymeric separable cap in said dispensing aperture comprising a plurality of angled channels, the channels comprising an entry portion opposite a terminal end and a vent region therebetween;
- and
- a displaceable handle having a lift end liftable from a stowage position to an opening position wherein an angle between said lift end and said longitudinal axis is decreased, said handle having an elastic characteristic wherein said handle can be lifted from and returned to said stowage position multiple times while remaining joined to a portion of the can end.
A ventable sealing arrangement for safely releasing pressure within a beverage container under pressure upon opening of the beverage container, the ventable sealing arrangement comprising:
- an aperture positioned about a longitudinal axis within which a resealable cap is located in a sealed condition;
- a plurality of circumferentially spaced projections within said aperture;
- and
- a plurality of angled channels within said aperture and associated with each of said plurality of spaced projections wherein said spaced projections are located within corresponding angled channels, at least one of said plurality of angled channels having a vent stop, said vent stop characterized by a recessed portion in said channel and a lip creating an angle with said recessed portion less than 90 degrees and greater than 0 degrees wherein said angled channels extend downwardly to said vent stop and wherein said lip angles upwardly from said vent stop to an exit end of each of said angled channels.
A can end for a container, the can end comprising:
- a metallic main portion positioned about a longitudinal axis comprising a first curl defining a radially outer perimeter of the can end, a center panel joined to said curl, a dispensing aperture in said center panel, and a second curl in said center panel defining a peripheral edge of said aperture including a plurality of projections extending radially inwardly into said dispensing aperture;
- and
- a polymeric separable cap in said dispensing aperture comprising a plurality of angled channels, the channels comprising an entry portion opposite a terminal end and a vent region therebetween comprising a vent stop in said vent region, the polymeric cap further comprising a flange extending radially outwardly beyond a perimeter of said aperture, an arcuate lower wall extending downwardly relative to a lower surface of said separable cap, said arcuate lower wall located radially inwardly from said flange and at least partially located within said aperture, said flange in sealing engagement with said second curl.
