Abstract
An inhaler has a housing having a patient port and a cover rotatable about a cover axis between a closed position in which the cover covers the patient port, and an open position in which the patient port is accessible, a spring surrounding a medicament container in which the cover axis intersects the container, and in which the cover is configured to drive the resilient structure to store energy therein upon rotation from the closed position towards the open position.
Core Innovation
The invention relates to an inhaler with a housing that has a patient port and a cover rotatable about a cover axis between a closed position and an open position. The cover covers the patient port in the closed position and the patient port is accessible in the open position. An energy storage arrangement is provided within the housing to store energy in response to cover rotation from the closed position towards the open position.
The energy storage arrangement includes a resilient member that defines a void for receiving a medicament container. The cover axis intersects the void so that the cover is configured to drive the resilient member to store energy therein upon rotation from the closed position towards the open position. The same concept is expressed in terms of an extensible resilient structure defining the void, where the cover drives the resilient structure in tension to store energy upon rotation from the closed position towards the open position.
In additional refinements, the cover drive is converted into force for the resilient member by using a cam to produce a linear force. A cam member is provided that is offset from the cover axis and engages an engagement formation connected with the energy storage arrangement. The arrangement can further include a sleeve for transferring force between the cover and the resilient member, including configurations where force transfer is achieved through components connected at positions offset from the cover axis.
Claims Coverage
The document provides two independent claim categories focused on an inhaler with a rotatable cover that drives a resilient energy-storage element defining a void for a medicament container, with the cover axis intersecting the void or tensioning an extensible resilient structure. Across the independent claims, the inventive features are the cover-to-energy-storage drive and the resilient structure geometry for storing energy.
Rotatable cover driving resilient energy storage across closed to open positions
An inhaler comprising a housing with a patient port and a cover rotatable about a cover axis between a closed position in which the cover covers the patient port, and an open position in which the patient port is accessible; an energy storage arrangement within the housing comprising a resilient member that defines a void for receiving a medicament container; the cover axis intersects the void; and the cover configured to drive the resilient member to store energy therein upon rotation from the closed position towards the open position.
Extensible resilient structure tensioned by rotatable cover
An inhaler comprising a housing with a patient port and a cover rotatable about a cover axis between a closed position in which the cover covers the patient port, and an open position in which the patient port is accessible; an extensible resilient structure within the housing defining a void for receiving a medicament container; and the cover configured to drive the resilient structure in tension to store energy therein upon rotation from the closed position towards the open position.
Cam producing linear force during cover rotation
An inhaler wherein a cam is included to generate a linear force on the resilient member/resilient structure when the cover rotates from the closed position towards the open position.
Offset cam member engaging an engagement formation
An inhaler wherein the cam includes a cam member driven by the cover, the cam member offset from the cover axis, and the cam member engaging an engagement formation/receiving formation connected to the energy storage arrangement/resilient structure.
Sleeve transferring force from cover to resilient energy storage
An inhaler wherein an energy storage arrangement includes a sleeve that transfers force from the cover to the resilient member/resilient structure, including a sleeve that surrounds at least part of the resilient structure and is connected to it at a position offset from the cover axis.
Extensible resilient portion storing energy in tension
An inhaler wherein the resilient portion is an extensible portion configured to store energy in tension.
Cylindrical resilient body with openings
An inhaler wherein the resilient portion is configured as a cylindrical body with a plurality of openings.
Overall, the independent claims cover an inhaler where a rotatable cover transitions between a closed and open position and drives an energy storage arrangement that defines a void for receiving a medicament container. The claim refinements further specify cam-based linear force conversion, optional sleeve-mediated force transfer, and resilient structure details such as extensible tension configuration and cylindrical spring geometry with openings.
