Container closure and seal with protective lip

Claim 2

A closure for a container comprising a metal cap having a raised top portion defined by a score line, the upraised portion being removable along the score line to provide an opening, a sealing member of resilient material compressibly positioned within the cap with a portion thereof extending around the score line and up into the upraised top portion so that when the upraised portion is removed, the sealing member expands and covers the edge of the cap opening.

Claim 3

A closure for a container comprising a metal cap having integral attaching portion means generating an opening in the cap including a tear tab secured to the integral attaching portion of the cap, a score line defining a panel to be removed by pulling the tear tab so as to provide the opening, the tear tab having a nose portion extending outside the area defined by the score line so that when the tear tab is lifted, a downward force is imposed on the nose portion with a resultant upward force on the attaching portion and the panel so as to sever the metal and remove the panel, and a sealing liner of resilient material in the cap to effect a seal between cap and container and extend inside the score line such that when the panel is removed, the resilient material expands around the severed metal edge of the opening.

Claim 4

A closure for a container comprising a metal cap having integral attaching portion means generating an opening in the cap including a tear tab secured to the integral attaching portion of the cap, a score line defining a panel to be removed by pulling the tear tab so as to provide the opening, the tear tab having a nose portion extending outside the area defined by the score line so that when the tear tab is lifted, a downward force is imposed on the nose portion with a resultant upward force on the attaching portion and the panel so as to sever the metal and remove the panel, and a sealing liner of resilient material in the cap to effect a seal between cap and container and extend inside the score line such that when the panel is removed, the resilient material expands around the severed metal edge of the opening.

Claim 5

A closure as described in claim 2, wherein the cap has a skirt portion formed by bending the end thereof onto itself to facilitate pressure retention of the cap to the container.

Claim 6

A closure for use with a container having a rim defining a mouth opening comprising a cap having an annular skirt and integral top portion, the skirt and top joined by a corner radius, a ring liner in the cap and positioned along said corner radius and top, said liner being of an elastomeric material and compressed in the cap, disposed to seal the rim of the container and define a pour out opening under the cap top portion, a removable panel in the cap for providing the pour out opening upon removal, said panel being defined by a continuous outline in said top portion, the panel extending in radial overlapping relation with the liner at its pour out opening perimeter, and means connected to said panel for removal thereof from the cap, whereupon the compressed liner outwardly expands to cover the edge formed in the cap by panel removal.

Claim 7

A closure for use with a container having a rim defining a mouth opening comprising a cap having an annular skirt and integral top portion, the skirt and top joined by a corner radius, a ring liner in the cap and positioned along said corner radius and top, said liner being of an elastomeric material and compressed in the cap, disposed to seal the rim of the container and define a pour out opening under the cap top portion, a removable panel in the cap for providing the pour out opening upon removal, said panel being defined by a continuous outline in said top portion, the panel extending in radial overlapping relation with the liner at its pour out opening perimeter, and means connected to said panel for removal thereof from the cap, whereupon the compressed liner outwardly expands to cover the edge formed in the cap by panel removal.

Claim 8

The closure defined in claim 4, wherein the cap is formed of metal and the skirt thereof comprises a lower annular portion that is bent to reversed adjacent relationship with the adjacent part of the skirt, whereby at least the lower portion of the skirt is two layers of metal encircling the container mouth opening.

Claim 9

The closure defined in claim 4, wherein said panel is raised in the top portion of the cap and spaced radially inwardly from said corner radius.
