Composite end panel for can or similar container

Claim 2

An improved method of fastening a paper laminate panel to the body of a can or similar container comprising the steps of: cutting the end panel, having interior and exterior surfaces, from a sheet of laminate material, applying an adhesive sealant to the interior surface periphery of said end panel. securing sand adhesive-covered end panel to an end of said container body with at least a portion of said interior surface periphery overlying the outer surface of said body, applying an annular band or hoop of heat-shrinkable plastic over the exterior surface periphery of said end panel, and heating said band or hoop to shrink the same, thereby further securing said end panel to said body and preventing end panel delamination and separation.

Claim 3

An improved method of fastening a paper laminate end panel to the body of a can or similar container comprising the steps of: cutting the end panel from a sheet of laminate material, applying an adhesive sealant to the periphery of said end panel, securing said adhesive covered end panel to an end of said container body with at least a portion of said periphery overlying the outer surface of said body, said end panel being formed with a plurality of gussets in said periphery to enhance the flexibility thereof, whereby said end panel may be attached to said body without excessive wrinkling, applying an annular band of heat shrinkable plastic over said end panel periphery, and heating said band to shrink said plastic thereby further securing said end panel to said body and preventing end panel delamination and separation.

Claim 4

An improved method of fastening a paper laminate end panel to the body of a can or similar container comprising the steps of: cutting the end panel from a sheet of laminate material, applying an adhesive sealant to the periphery of said end panel, securing said adhesive covered end panel to an end of said container body with at least a portion of said periphery overlying the outer surface of said body, said end panel being formed with a plurality of gussets in said periphery to enhance the flexibility thereof, whereby said end panel may be attached to said body without excessive wrinkling, applying an annular band of heat shrinkable plastic over said end panel periphery, and heating said band to shrink said plastic thereby further securing said end panel to said body and preventing end panel delamination and separation.

Claim 5

The method of claim 2, wherein an annular channel is formed in said periphery of said end panel prior to securing the same to said body, said channel having a substantially vertical inner sidewall and an upwardly and outwardly sloping outer sidewall, the nonchannel portion of said end panel being of a size admitting said container body to fit thereover, with said body in close contact with said inner sidewall of said channel.

Claim 6

The method of claim 3, wherein said band overlaps the edge of said end panel, thereby sealing said edge and preventing wicking.

Claim 7

The method of claim 4, and the upper edge of said band is heat sealed to said body, thereby improving the moisture resistance of the seal.

Claim 8

The method of claim 4, and a fillet of sealant on the interior of the container at the juncture of said body and said end panel.

Claim 9

An improved container comprising a container body, a laminated end panel adhesively attached to an end of said body, said end panel comprising a central panel portion and a peripheral portion, said peripheral portion having a plurality of flexibility enhancing gussets formed therein, at least at part of said peripheral portion being attached to the outer surface of said body, and an annular band of heat-shrinkable plastic material overlying the part of said peripheral portion attached to said outer body surface for further securing said end panel to said body and preventing end panel delamination and separation.

Claim 10

An improved container comprising a container body, a laminated end panel adhesively attached to an end of said body, said end panel comprising a central panel portion and a peripheral portion, said peripheral portion having a plurality of flexibility enhancing gussets formed therein, at least at part of said peripheral portion being attached to the outer surface of said body, and an annular band of heat-shrinkable plastic material overlying the part of said peripheral portion attached to said outer body surface for further securing said end panel to said body and preventing end panel delamination and separation.

Claim 11

The container of claim 7, wherein an annular channel is formed in said peripheral portion, said channel having a substantially vertical inner sidewall, and said central panel portion being of a size admitting said body to fit thereover, with said body in close contact with said inner sidewall of said channel.

Claim 12

The container of claim 8, wherein said band overlaps the edge of said end panel, thereby sealing said edge and preventing wicking.

Claim 13

The method of claim 9 and a fillet of sealant on the interior of the container at the juncture of said body and said end panel.
