The invention relates to a system composed of an inhaler and a capsule, preferably intended for single use. The capsule contains a preferably powdered pharmaceutical preparation which, for inhalation, is expelled from the capsule through at least one hole. The capsule comprises as capsule elements a capsule cap and a capsule body, at least one of which comprises at least one prefabricated hole. The prefabricated hole in the capsule is sealed off in the transporting state of the system and is open in the usage state. The hole is exposed by actuation of a pulling mechanism. Prior to this the hole is closed off by a capsule receptacle or a film. In one embodiment the capsule may be present in two different states, for example in different insertion positions of the capsule elements. In the first state the prefabricated hole is closed off and in the second it is exposed. Also shown is an inhaler suitable as a disposable product, which is manufactured from thermoformed parts or from blister film.
System comprising an inhaler and a capsule for use as a reservoir for a pharmaceuticals wherein the capsule comprises two capsule elements open at one end, the two capsule elements including a capsule body (2) and a capsule cap (1), which are fitted into one another telescopically through their respective openings so as to form a cavity, the inhaler comprises a capsule chamber (74), the capsule body (2) and/or the capsule cap (1) each comprise, in addition to the respective opening at one end, at least one prefabricated hole (7, 6), before the inhaler is used, the capsule (71) is stored in a capsule receptacle (173a), the capsule receptacle (173a) sealing off at least one hole (72a, 72b) which leads into the cavity of the capsule (71), the capsule receptacle (173a) is at least partly arranged in the capsule chamber (74), and the capsule receptacle (173a) is removed from the capsule chamber (74) by means of a pulling mechanism, such that when the capsule receptacle (173a) is removed, the capsule (71) remains in the capsule chamber (74), the inhaler comprises a mouthpiece (78) with a mouth tube (78d) that connects the capsule chamber (74) to an air outlet, a component that forms or encompasses the capsule receptacle (173a) extends through the mouth tube (78d) in the inhaler, the inhaler comprises a tongue, pin or bar (75) that delimits the capsule chamber (74) and extends through the capsule receptacle (173a), and the capsule receptacle (173a) comprises a recess through which the tongue, pin or bar (75) slides during relative movement between the component and the capsule chamber (74).
