A dispensing device for dispensing medication from a medication container, comprising; a housing; and a drive member extending within said housing and engageable with the medication container; characterized in that the dispensing device further comprises: at least one first ramp surface fixed relative to said housing; a driver movable within said housing from a first position to a second position to move said drive member for forcing medication from the medication container, said driver including at least one second ramp surface; and a plunger (40, 45) including at least one push module movable relative to said housing from a ready position to a plunged position; said at least one first ramp surface and said at least one second ramp surface having a complementary configuration to cause said driver to be moved toward said second position by a driving force applied to said at least one second ramp surface by said at least one push module as said at least one push module simultaneously engages both said at least one first ramp surface and said at least one second ramp surface during movement from said ready position to said plunged position, said complementary configuration including converging regions of said at least one first ramp surface and said at least one second ramp surface sized and positioned to prevent said at least one push module from continuing to move toward said plunged position until said driver is moved toward said second position by said at least one push module. a housing; and a drive member extending within said housing and engageable with the medication container; characterized in that the dispensing device further comprises: at least one first ramp surface fixed relative to said housing; a driver movable within said housing from a first position to a second position to move said drive member for forcing medication from the medication container, said driver including at least one second ramp surface; and a plunger (40, 45) including at least one push module movable relative to said housing from a ready position to a plunged position; said at least one first ramp surface and said at least one second ramp surface having a complementary configuration to cause said driver to be moved toward said second position by a driving force applied to said at least one second ramp surface by said at least one push module as said at least one push module simultaneously engages both said at least one first ramp surface and said at least one second ramp surface during movement from said ready position to said plunged position, said complementary configuration including converging regions of said at least one first ramp surface and said at least one second ramp surface sized and positioned to prevent said at least one push module from continuing to move toward said plunged position until said driver is moved toward said second position by said at least one push module. at least one first ramp surface fixed relative to said housing; a driver movable within said housing from a first position to a second position to move said drive member for forcing medication from the medication container, said driver including at least one second ramp surface; and a plunger (40, 45) including at least one push module movable relative to said housing from a ready position to a plunged position; said at least one first ramp surface and said at least one second ramp surface having a complementary configuration to cause said driver to be moved toward said second position by a driving force applied to said at least one second ramp surface by said at least one push module as said at least one push module simultaneously engages both said at least one first ramp surface and said at least one second ramp surface during movement from said ready position to said plunged position, said complementary configuration including converging regions of said at least one first ramp surface and said at least one second ramp surface sized and positioned to prevent said at least one push module from continuing to move toward said plunged position until said driver is moved toward said second position by said at least one push module.
