Patent ID: 8556848

Claim:
A drug containing device comprising: a barrel; a valve disposed in said barrel, said valve including: a body configured for slideable liquid tight engagement with said barrel, said body having a proximal end, a distal end, and a channel extending therebetween, said channel having a proximal portion and a distal portion; and, a poppet sealingly and slidably disposed in said channel to selectively move between first and second positions relative to said body, said poppet having a proximal end, a distal end, and a fluid channel, said fluid channel defined in said poppet and extending from an outlet opening located distally of said distal end of said body; wherein, a first portion of said poppet is in engagement with said barrel, a second portion of said poppet is in engagement with said channel, the frictional resistance against movement generated at the interface between said first portion of said poppet and said barrel being greater than the frictional resistance against movement generated at the interface between said second portion of said poppet and said channel; and, wherein, with said poppet in said first position, said poppet defining a liquid tight seal in said channel such that liquid flow through said channel is prevented, and, wherein, with said poppet in said second position, said fluid channel being in open communication with said proximal portion of said channel so as to define a liquid flow path from said proximal portion of said channel to said outlet opening.
