Abstract
Abstract An inhalator the case of which is provided with a reception space in its outer peripheral surface for insertably carrying a capsule containing a substance to be inhaled. An outer cover is mounted on the case and is movable with respect to the case between specified positions under the action of a spring bias. In one position the cover exposes the reception space to permit insertion and removal of capsules at which position the cover is interlocked with the case. Upon insertion of a capsule the cover is automatically unlocked from the case and moves under the spring bias to a position to cover the capsule and to a further position at which cutting members coupled to the cover move into the reception space to open the capsule.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
92 words
An inhalator for pulverulent substances comprising an inhalator case having an inlet and an outlet for passing respiratory air, a reception space formed on the outer periphery of the case for insertably receiving a rupturable capsule containing a pulverulent substance, means for mounting a cover portion on the inhalator case for movement with respect thereto between a first position whereat the cover portion encloses the capsule in the reception space and a second position at which the cover portion uncovers the capsule in the reception space to permit removal and replacement thereof.
Claim 2
Dependent Claim
92 words
An inhalator for pulverulent substances comprising an inhalator case having an inlet and an outlet for passing respiratory air, a reception space formed on the outer periphery of the case for insertably receiving a rupturable capsule containing a pulverulent substance, means for mounting a cover portion on the inhalator case for movement with respect thereto between a first position whereat the cover portion encloses the capsule in the reception space and a second position at which the cover portion uncovers the capsule in the reception space to permit removal and replacement thereof.
Claim 3
Dependent Claim
45 words
An inhalator as claimed in claim 1, wherein said means for mounting the cover portion is rotatable, and is arranged on the outer surface of said inhalator case, said cover portion having an aperture for traversal by the capsule from and to said reception space.
Claim 4
Dependent Claim
57 words
An inhalator as claimed in claim 1, wherein a stop pin is guided in a longitudinal displaceable manner within said case and a notched portion is provided in said cover portion so that in said second position of the cover portion the stop pin engages the notched portion and immobilises the cover portion in said second position.
Claim 5
Dependent Claim
100 words
An inhalator as claimed in claim 3, wherein an ejector member rigidly coupled to said stop pin is displaceably arranged within the inhalator case, and first spring means is coupled to the ejector means to constantly urge the ejector member to eject a capsule from the reception space, and concomitantly move said stop pin into the notched portion of the cover portion whereby during insertion of a capsule into the reception space, the ejector member is moved out of the reception space against the force of said spring means, the stop pin concomitantly cancelling said immobilisation of said cover portion.
Claim 6
Dependent Claim
37 words
An inhalator as claimed in claim 1, further comprising opening means to open a capsule in the reception space, said opening means being mounted to said cover portion to be moved together therewith into said reception space.
Claim 7
Dependent Claim
23 words
An inhalatoR as claimed in claim 5, wherein said opening means comprises two blades which cut the capsule open vicinal to its extremities.
Claim 8
Dependent Claim
62 words
An inhalator as claimed in claim 6, wherein said means for mounting said cover portion on the inhalator case for movement with respect thereto includes a spring member under the biasing force of which said cover portion is moved from said first position, into said second position and also into a third position at which said opening means enters said reception space.
Claim 9
Dependent Claim
28 words
An inhalator as claimed in claim 1, wherein said reception space communicates with the inside of the inhalator case via an air inlet and an air outlet opening.
Claim 10
Dependent Claim
28 words
An inhalator as claimed in claim 8, wherein the blades of said opening means are moved into the reception space through said air inlet and air outlet openings.
Claim 11
Dependent Claim
25 words
An inhalator as claimed in claim 9, wherein the blades of said opening means are movable in slots of the walls of said inhalator case.
Claim 12
Dependent Claim
