Claims14
A dry powder inhaler for a capsule containing dry powder, the dry powder inhaler comprising:
- a mouth piece with a mouth portion, wherein an opening of the mouth portion leads into a duct;
- an intermediate piece, which is attached to a distal end of the duct of the mouth piece;
- a mesh piece, which is attached to the intermediate piece;
- a covering body;
- a one-piece base body comprising a capsule chamber portion and being attached to the covering body, wherein a base body opening, which is arranged towards the mouth piece, leads into a capsule chamber of the capsule chamber portion, wherein the duct and the capsule chamber extend along a common longitudinal axis when the mouth piece abuts the base body, and wherein a hinge directly connects the mouth piece and the one-piece base body, wherein the one-piece base body comprises an annular-shaped groove arranged around the base body opening, and wherein the intermediate piece comprises an annular-shaped distal end for engaging with the annular-shaped groove;
- and
- an actuator button movable relative to the one-piece base body from a normal position to a perforation position along an actuation direction, wherein the actuation direction is perpendicular to the longitudinal axis, and wherein perforation needles attached to the actuator button extend into the capsule chamber when the actuator button is in the perforation position.
A dry powder inhaler for a capsule containing dry powder, the dry powder inhaler comprising:
- a mouth piece with a hinge section;
- a covering body;
- and
- a one-piece base body comprising a capsule chamber portion and being attached to the covering body, wherein a hinge directly connects the mouth piece and the one-piece base body, wherein the hinge section of the mouth piece is connected to a hinge section of the one-piece base body via a ball joint snap-on connection for pivoting around a hinge axis, wherein the one-piece base body is attached to the covering body by a latching connection, wherein the one-piece base body comprises a ratchet of the latching connection, and an outer surface opposed to the ratchet;
- and wherein the covering body comprises:
- a first inner protrusion for a third latching connection, the first inner protrusion comprising a hole receiving the ratchet of the one-piece base body;
- and
- a second inner protrusion abutting said outer surface of the one-piece base body.
A dry powder inhaler for a capsule containing dry powder, the dry powder inhaler comprising:
- a mouth piece with a hinge section;
- a covering body;
- and
- a one-piece base body comprising a capsule chamber portion and being attached to the covering body, wherein a hinge directly connects the mouth piece and the one-piece base body, wherein the hinge section of the mouth piece is connected to a hinge section of the one-piece base body via a ball joint snap-on connection for pivoting around a hinge axis, wherein the one-piece base body is attached to the covering body by a latching connection, wherein the covering body further comprises an opening with an inward cut-out for receiving a plate portion of the one-piece base body, and wherein the one-piece base body further comprises the plate portion with an outward edge contacting at least partly the inward cut-out.
