Dose indicating device

An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container, the indicating device comprising:

• a housing component;
• an actuator reciprocally moveable a plurality of actuations along a linear path;
• and
• an indicator member rotatably mounted to said housing component about a rotation axis, said indicator member comprising numerical dosage indicia corresponding to a set of consecutive whole numbers, wherein said set of consecutive whole numbers includes a first number and a last number, wherein the difference between the first number and the last number is at least 60, wherein said indicator member is rotatable a maximum amount to the next consecutive whole number in response to each consecutive reciprocal movement of said actuator, wherein said indicator member is rotatable between at least a first position wherein said first number is visible to a user and a last position wherein said last number is visible to a user, and wherein said indicia are maintained a fixed distance relative to said rotation axis as said indicator member is rotated between said first and last positions, wherein said set of consecutive whole numbers are arranged in a helical pattern on said indicator member.

A dispensing device for dispensing metered dosages of medicament comprising:

• a container comprising a plurality of dosages of medicament, wherein said container has a first end comprising a valve stem and an opposite second end;
• a housing component coupled to said second end of said container;
• an actuator reciprocally movable in a plurality of actuations;
• a gear engageable by said actuator and rotatable about a rotation axis;
• and
• an indicator member rotatably mounted to said housing component about said rotation axis, said indicator member comprising numerical dosage indicia corresponding to a set of consecutive whole numbers, wherein said set of consecutive whole numbers includes a first number and a last number, wherein the difference between the first number and the last number is at least 100, wherein said indicator member is rotatable between at least a first position wherein said first number is visible to a user and a last position wherein said last number is visible to a user, and wherein none of said indicia overlap so as to cover other of said indicia as said indicator member is rotated between said first and last position.

A method of indicating the number of metered dosages that have been dispensed from or remain in a container, the method comprising:

• successively dispensing a plurality of metered dosages of medicament from a container;
• rotating a gear about a rotation axis in response to each dispensation of a metered dose of medicament;
• rotating an indicator member an incremental amount about said rotation axis in response to each rotation of said gear;
• and
• successively displaying numerical dosage indicia disposed on said indicator member, wherein said dosage indicia corresponds to a set of consecutive whole numbers, wherein said set of consecutive whole numbers includes a first number and a last number, wherein the difference between the first number and the last number is at least 100, and maintaining said indicia a fixed distance relative to said rotation axis while successively displaying said numerical dosage indicia.
