ABSTRACT:
A device defining a chamber for receiving a substance and a thermoplastic portion in fluid communication with the chamber is provided along with a method of filling and sealing the substance within the chamber. The thermoplastic portion defines a penetrable region that is penetrable by a filling member and is heat resealable to hermetically seal an aperture therein by applying laser radiation at a predetermined wavelength and power. The thermoplastic portion comprises a thermoplastic body defining a predetermined wall thickness and includes a styrene block copolymer, an olefin and a predetermined amount of pigment allowing the body to absorb laser radiation at the predetermined wavelength, substantially prevent the passage of radiation through the predetermined wall thickness, and hermetically seal the aperture in the penetrable region in a predetermined time period. The body includes a predetermined amount of lubricant that reduces friction forces at an interface of the filling member and body during penetration thereof.
