Abstract

A container such as a can of carbonated beverage, including an upwardly open metal body having a sidewall with an annular upper portion having a reduced-diameter neck formed therein, and a metal top structure such as a lid having an annular portion secured to the annular upper portion of the sidewall along an annular seam extending outwardly and substantially horizontally or downwardly, from the sidewall. The sidewall edge portion is formed into an outwardly projecting annular flange immediately above the neck, the annular lid portion overlies the annular flange, and the seam includes a metal member holding the annular peripheral lid portion and the annular flange together. The lid may be upwardly domed by internal pressure. A method of producing the container by filling it, adhesively bonding the lid to the flange, and forming the metal seam member.

Dependent claims

A carbonated beverage package comprising:

(a) a metal can body having an open upper extremity and including a sidewall with an inner surface, an outer surface and an annular upper edge portion at said upper extremity;
(b) a body of a carbonated beverage contained within the can;
and
(c) a can lid having an upper surface, a lower surface and an annular peripheral portion secured to the upper edge portion of the sidewall along an annular seam, the lid being upwardly domed by positive internal pressure caused by the carbonated beverage within the can, the lid defining an aperture therein for pouring or drinking liquid from the can, and further including a flexible closure member extending entirely over the aperture and peelably bonded to the upper surface of the lid;
wherein the improvement comprises, in combination,
(d) the upper edge portion of the sidewall being formed into an outwardly projecting annular flange with an upper surface that is continuous with the inner surface of the sidewall, the sidewall being formed with a reduced-diameter neck immediately below the annular flange;
(e) the annular peripheral lid portion overlying the annular flange and having no return bend;
(f) the lower surface of the lid at said annular peripheral portion facing and being adhesively bonded to the upper surface of the annular flange;
and
(g) the seam including a metal member extending around the annular peripheral lid portion and bearing against the upper surface of the lid to hold the annular peripheral lid portion and the annular flange together.
