In one aspect of the invention, a dental amalgam capsule includes a body, a cap, a dental amalgam alloy, and mercury. In further detail, the body has a hollow interior with an open first end which includes an opening surrounded by an end wall. The cap has a hollow interior with an open first end and an interior surface. The interior surface includes an annular recess disposed about a longitudinal axis of the cap, with the annular recess including a sealing surface angled at less than 90 degrees relative to the longitudinal axis. The sealing surface is capable of contacting at least a portion of the end wall, thereby forming a seal with the end wall.

1. A capsule for holding a dental amalgam, comprising:a body having a hollow interior with an open first end which includes an opening surrounded by an end wall, the end wall having a male sealing lip section and a radially upwardly and outwardly extending inclined surface which includes a non-sealing portion; and a cap having an end wall and a hollow interior with an open first end and a concave interior surface, the interior surface including an annular recess disposed about a longitudinal axis of the cap, the annular recess including a truncated conical sealing surface inclined at an angle of less than 90 degrees relative to the longitudinal axis of the cap, the male sealing lip section and the sealing surface of the annular recess capable of forming a seal when positioned in a contacting relationship so that the dental amalgam is enclosed within the hollow interiors of the body and the cap, the non-sealing portion located radially inward of the sealing surface of the annular recess when the seal is formed, the non-sealing portion of the inclined surface deflecting the dental amalgam in a direction away from the seal formed between the male sealing lip section and the sealing surface of the annular recess, thereby inhibiting the dental amalgam moving between the end wall of the cap and the body from penetrating the seal when the sealed amalgam capsule is shaken.
