Dispensing device

A medicament dispensing device for dispensing metered dosages of medicaments, the medicament dispensing device comprising:

• an actuator housing having a longitudinally extending cavity;
• a container disposed in said cavity and comprising a cylinder, said cylinder adapted to hold the medicaments, said container reciprocally moveable relative to said actuator housing along a longitudinal axis, wherein said cylinder has a first outer diameter;
• and
• an indicating device comprising:
• an indicator housing comprising a tubular portion connected to said container, wherein said indicating device is reciprocally moveable with said container relative to said actuator housing, said tubular portion having a second outer diameter, wherein said second outer diameter is of substantially the same diameter as said first outer diameter, and said indicator housing further comprising a longitudinally extending side wall having a viewing window formed therein, wherein said viewing window and said cylinder are longitudinally spaced apart with said tubular portion positioned between said viewing window and said cylinder;
• and
• an indicator rotatably mounted in said indicator housing, said indicator comprising dosage indicia visible through said viewing window.

A method of assembling a medicament dispensing device comprising:

• providing an actuator housing having a longitudinally extending cavity;
• providing a container comprising a cylinder having a first outer diameter, said cylinder adapted to hold a medicament;
• providing an indicating device comprising:
• an indicator housing comprising a tubular portion having a second outer diameter and defining a longitudinal axis, wherein said second outer diameter is substantially the same as said first outer diameter, and said indicator housing further comprising a side viewing window opening in a radial direction substantially perpendicular to said longitudinal axis;
• and
• an indicator rotatably mounted in said indicator housing, said indicator comprising dosage indicia visible through said viewing window;
• fixedly connecting said tubular portion of said indicator housing to said container;
• disposing said container in said cavity of said actuator housing;
• and
• connecting said container to said actuator housing, wherein said container and said indicator housing are reciprocally moveable relative to said actuator housing along a longitudinal axis.

A method of dispensing medicament comprising:

• providing an actuator housing having a longitudinally extending cavity;
• providing a container disposed in said cavity and comprising a cylinder, said cylinder adapted to hold the medicaments, said container reciprocally moveable relative to said actuator housing along a longitudinal axis, wherein said cylinder has a first outer diameter;
• providing an indicating device comprising:
• an indicator housing comprising a tubular portion connected to said container, wherein said indicating device is reciprocally moveable with said container relative to said actuator housing, said tubular portion having a second outer diameter, wherein said second outer diameter is substantially the same as said first outer diameter, and said indicator housing further comprising a side viewing window opening in a radial direction substantially perpendicular to said longitudinal axis;
• and
• an indicator rotatably mounted in said indicator housing, said indicator comprising dosage indicia visible through said viewing window;
• reciprocally moving said container and said indicating device relative to said actuator housing and thereby dispensing a least one metered dosage of medicament.
