Embodiment Construction

[0026] In order to combine the advantages of a relative and precise indication of the number of remaining doses of the inhaler device counter, it has been found that an indication using a pointer-gauge type display arrangement gives an intuitive relative indication of the number of remaining doses in the inhaler device. Good combination with accurate readings. Furthermore, it has been found that integrating the static parts of the display arrangement within the transparent part of the counter housing improves the design of the counter display arrangement. In one embodiment, the static part is integrated within the transparent part of the housing using in-mold labeling (IML) technology.

[0027] Figure 1 shows a schematic example of an inhaler device 10 comprising a counter 20 according to the invention. The inhaler device comprises an actuator body 30 with a mouthpiece 40 through which medicament is delivered to the user; and a container counter assembly. In this embodiment,...

Abstract

Inhaler device counter (20) for displaying the number of remaining doses in an inhaler device (10). The counter (20) comprises a counter mechanism and a display arrangement (60), wherein the display arrangement (60) is of pointer-gauge type with a static display section (90) provided as an integrated part of a transparent display containing part (150, 300) of a counter housing (70). There is also provided a method.

Description

technical field [0001] The present invention relates to the field of inhaler device counters, and in particular to their display arrangement and a method of providing the display arrangement. Background technique [0002] Many types of drugs are supplied in fluid form, such as solutions or particle suspensions in propellants or emulsions, and are suitable for inhalation by the patient from the oral cavity. As an example, a container might contain an asthma medication such as fluticasone propionate. [0003] To deliver the drug to the patient, the canister incorporates an actuator, operating as a system commonly known as a metered dose inhaler (MDI) system. The actuator includes a housing having an open container loading end and an open mouthpiece. A nozzle element is disposed within the housing and includes a stem receiving aperture in communication with the nozzle opening. This opening is aligned with the mouthpiece. To receive a correctly metered dose of medicament fro...
