Abstract:
1. A device defining a chamber for receiving a substance and a thermoplastic portion in fluid communication with the chamber, the thermoplastic portion defining 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 thereto, wherein the thermoplastic portion comprises a thermoplastic body defining a predetermined wall thickness and including (i) a styrene block copolymer; (ii) an olefin; (iii) a predetermined amount of pigment that allows the body to substantially absorb laser radiation at the predetermined wavelength and 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; and (iv) a predetermined amount of lubricant that reduces friction forces at an interface of the filling member and body during penetration thereof.
