Patent ID: 7726357

Claim:
An assembly, comprising: a device defining a chamber, and including a resealable portion for sealing a predetermined substance within the chamber, wherein the resealable portion includes: a body defining a predetermined wall thickness, a penetrable region that is penetrable by a filling member and is heat resealable to hermetically seal an aperture therein by applying laser radiation from a laser source at a predetermined wavelength and power thereto to form a gas-tight seal between the resealable portion and the substance in the chamber, wherein the penetrable region defines a predetermined color and opacity that (i) substantially absorbs the laser radiation at the predetermined wavelength and substantially prevents the passage of the radiation through the predetermined wall thickness thereof, and (ii) that causes the laser radiation at the predetermined wavelength and power to hermetically seal the aperture in the penetrable region thereof in a predetermined time period; a filling assembly including a filling member for penetrating the resealable portion and introducing a substance through the resealable portion and into the chamber; a substance source coupled in fluid communication to the filling assembly for introducing the substance through the filling member and into the chamber; and a laser source connectable in thermal communication with the resealable portion for applying laser radiation at the predetermined wavelength and power thereto.
