  • Publication number: 20180043102
    Abstract: A multi-piece plunger configured to be slideably advanced through a syringe barrel to expel fluid therefrom is provided. The plunger includes a head portion having a proximal end, a distal end, and an annular sidewall extending therebetween. The sidewall can define at least two annular grooves. The plunger also includes annular seals disposed within each of the at least two annular grooves, such that at least a portion of each of the annular seals protrudes radially beyond an outer surface of the sidewall to form a slideable seal with an inner sidewall of the syringe barrel. The head portion can be formed from a first material, such as a rigid plastic material, and the annular seals can be formed from a second material, such as a thermoset rubber or a thermoplastic elastomer. A prefilled syringe including the multi-piece plunger is also provided herein.

  • Patent number: 7824747
    Abstract: A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.
