Abstract

A plunger configured as described herein provides geometry optimizations to minimize friction magnitude and variability during use by maintaining low deformation under large extrusion forces. More specifically, plunger embodiments described herein minimize a contact area between the plunger and a syringe or chamber, while also maintaining high contract pressures to maintain container closure integrity. Moreover, the plunger embodiments are configured to have minimal or no increase in the contact area under high loads associated with the delivery of viscous products.
