An inhaler for administering medicament by inhalation and a method of manufacturing a housing of the same, the inhaler including a housing formed as a single-piece moulding having a first portion (18) which, in normal use, comes into contact with medicament and the mouth or nose of a user through which medicament is inhaled and a second portion (20) which defines at least part of the outer surface of the housing and, in normal use, does not come into contact with medicament or the mouth or nose of a user through which medicament is inhaled, wherein the material constitution of at least part of the second portion (20) defining at least part of the outer surface of the housing is different to the material constitution of the first portion (18).
An inhaler for administering medicament by inhalation, including a housing formed as a single-piece molding having a first portion which, in normal use, is contactable with medicament and a mouth or nose of a user through which medicament is inhaled and a second portion which defines at least part of an outer surface of the housing and, in normal use, is not contactable with medicament or a mouth or nose of a user through which medicament is inhaled, at least part of the second portion defining at least part of the outer surface of the housing having a material constitution which is different to the material constitution of the first portion to allow identification of the medicament to be administered.
An inhaler for administering medicament by inhalation, comprising:
A method of manufacturing a housing of an inhaler for administering medicament by inhalation having a first portion which, in normal use, is contactable with medicament and a mouth or nose of a user through which medicament is inhaled and a second portion which defines at least part of an outer surface of the housing and, in normal use, is not contactable with medicament or a mouth or nose of a user through which medicament is inhaled, the method comprising the step of molding the first and second portions as a single piece, at least part of the second portion defining at least part of the outer surface of the housing being formed of a material of different constitution to that of the first portion to allow identification of the medicament to be administered.
A method of manufacturing a housing of an inhaler for administering medicament by inhalation having a first portion which, in use, is contactable with medicament and a mouth or nose of a user through which medicament is inhaled and a second portion which defines at least part of an outer surface of the housing and, in use, is not contactable with medicament or a mouth or nose of a user, said method comprising molding said first and second portions as a single piece, at least part of the second portion defining at least part of the outer surface of the housing being formed of a material of different constitution to that of the first portion to allow identification of the medicament to be administered.
