| (54) | Ramp actuator for engagement flange on removable dispenser cartridge |
| (57) An improved arrangement for removably coupling a replaceable cartridge (13) to a
housing of a dispenser (10) with the cartridge carrying a piston pump with a movable
piston element (57) to be coupled on insertion with an actuator plate(32) of the housing.
A ramp mechanism is provided on the actuator plate to engage the piston element and
during insertion of the cartridge into the housing move the piston element to a position
relative the actuator plate which facilitates proper coupling including a resilient
member (67) which prevents radial movement relative a catch member (100) of the housing
from a coupled orientation unless the resilient member is deflected from an unbiased
inherent configuration.
