Abstract
Official abstract text for this publication.
A method of sealing a peelable lid to a circumferential and inwardly projecting flange formed in a tubular metal can body, where the flange has a sealing surface having a substantially V-shaped profile. The method comprises pressing the peelable lid against the sealing surface of the flange using a punch, an engagement surface of the punch having a generally V-shaped profile such that the apex of the punch presses the peelable lid into the valley of the engagement surface of the flange.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of sealing a peelable lid to a circumferential and inwardly projecting flange formed in a tubular metal can body, comprising the steps of: (i) forming a V-shaped profile into a sealing surface of the flange; and (ii) after forming the V-shaped profile, engaging a V-shaped engagement profile of a punch with the peelable lid to press the peelable lid against the flange such that an apex of the punch engagement profile presses the peelable lid into a valley of the flange profile. 2. A method according to claim 1 , further comprising the step of applying heat to at least one of the peelable lid and the flange as the peelable lid is pressed against the flange. 3. A method according to claim 1 , wherein said step of pressing the peelable lid against the sealing surface of the flange using a punch substantially diminishes air pockets from between the peelable lid and the sealing surface of the flange. 4. A method according to claim 3 , wherein the step of pressing the peelable lid against the sealing surface of the flange using a punch substantially eliminates air pockets from between the peelable lid and the sealing surface of the flange.
