Claim:
A two-piece closing seal, comprising: an elongate, one-piece, integrally formed metal strip having mutually parallel, oppositely oriented inner and outer faces, and first and second oppositely disposed end portions with a medial portion positioned between said first and second end portions; and including: a cylindrically shaped insertion pin formed integrally in said metal strip adjacent said medial portion, protruding outwardly away from said inner face, and having a hollow, cup-shaped interior defined by a fully closed circular pin base that is flush with said medial portion, and a folded over cylindrical pin sidewall which is integral with said pin base, has an exterior surface, and extends outwardly to a fully open top; a connector through aperture disposed adjacent said first end portion of said metal strip, extending through both said inner and outer faces and having a circular plan shape that is closely received over said exterior surface of said insertion pin when said two-piece closing seal is in a sealed condition; a cylindrically shaped closure body formed integrally in said metal strip adjacent said second end portion, protruding outwardly away from said outer face, and having a hollow, cup shaped interior defined by a fully closed circular body base integral with said second end portion of said metal strip, and a body sidewall which is integral with said body base and extends outwardly to an enlarged rim surface with an axially adjacent mounting flange protruding radially inwardly therefrom; and a self-locking closing disk having a generally circular plan shape with an outer marginal edge portion securely retained between said rim surface and said mounting flange on said closure body, and a central aperture with radially inwardly protruding locking fingers with end edges that abuttingly engage said exterior surface of said insertion pin during assembly, and securely retain said two-piece closing seal in said sealed condition, whereby said first end portion of said metal strip is inserted through a portion of an article to be sealed, then flexed inwardly toward said medial portion, with said through aperture received over said insertion pin, and said second end portion of said metal strip is flexed inwardly toward said medial portion with said closure body and said closing disk mounted therein pressed onto said insertion pin over said first end portion of said metal strip, such that said locking fingers on said closing disk abuttingly engage said outside surface of said insertion pin to securely retain said two-piece closing seal in said sealed condition.
