Nebulizer and cartridge

A cartridge (3) for containing a fluid (2) to be nebulized by a nebulizer (1), the cartridge (3) comprising:

• an outer container (20) of the cartridge (3);
• and
• a closure part (23) having an opening (23D) for receiving a connecting element (9) of the nebulizer (1) for fluidically connecting the cartridge (3) to the nebulizer (1), wherein:
• the cartridge (3) defines an axis (A) which runs centrally through the opening (23D),
• the closure part (23) comprises a sealing wall (33) which is integrally formed, or formed as one piece, with the closure part (23) and located within the opening (23D) sealing the opening (23D) in an initial state of the cartridge,
• the sealing wall 33 is at least one of pierceable, breakable, and adapted to be pierced or broken by the connecting element 9,
• the sealing wall 33 comprises at least one recessed portion 33E of reduced thickness, the recessed portion 33E forming a predetermined breaking point of the sealing wall 33,
• the recessed portion 33E partitions the sealing wall 33 into a plurality of flexing portions 33F having substantially a same shape and/or a same size,
• the sealing wall 33 is configured to tear or break along the recessed portion 33E upon the connecting element 9 being pushed against the sealing wall 33, and
• the flexing portions 33F are configured to flex apart upon the connecting element 9 being pushed into the cartridge 3 and remain connected to the closure part 23 after the sealing wall 33 has been teared/broken.

A nebulizer (1) for a fluid (2), comprising:

• an insertable cartridge (3) for containing a fluid (2) to be nebulized by the nebulizer (1),
• an outer container (20) surrounding the cartridge (3);
• a closure (21) having an opening (23D) for receiving a connecting element (9) of the nebulizer (1) for fluidically connecting the cartridge (3) to the nebulizer (1),
• a holder (6) for holding the cartridge (3);
• a delivery mechanism (5) for delivering and/or pressurizing the fluid (2);
• and
• a connecting element (9) for fluidically connecting the cartridge (3) to the delivery mechanism (5) or a pump thereof, wherein:
• the closure (21) comprises a sealing wall (33) operating to seal the opening (23D) in an initial state of the cartridge (3), the opening 23D having at least one of a funnel-shape or tapered portion for aligning or guiding the connecting element (9) to the sealing wall (33), and
• the sealing wall (33) comprises a circumferential portion (33B) of reduced thickness forming a predetermined breaking point of the sealing wall (33), and a connecting portion (33C), operating such that the sealing wall (33) tears along the circumferential portion (33B) and tilts aside upon insertion of the connecting element (9).

A nebulizer (1) for a fluid (2), comprising:

• an insertable cartridge (3) with a closure (21) and a container (20) containing the fluid (2);
• a holder (6) for holding the cartridge (3);
• a delivery mechanism (5) for delivering and/or pressurizing the fluid (2);
• and
• a connecting element (9) for fluidically connecting the cartridge (3) to the delivery mechanism (5) or a pump thereof, wherein:
• the closure (21) of the cartridge (3) comprises an opening (23D) for receiving the connecting element (9) for fluidically connecting the cartridge (3) to the nebulizer (1), and
• the closure (21) comprises an integrally formed closure part (23) forming a sealing (S1, S7) with an integrally formed portion (20B) of an outer container (20) of the cartridge (3) as well as a sealing (S5, S6) with the connecting element (9) and/or a holder (6) thereof.

A nebulizer (1) for a fluid (2), comprising:

• an insertable cartridge (3) with a closure (21) and a container (20) containing the fluid (2);
• a holder (6) for holding the cartridge (3);
• a delivery mechanism (5) for delivering and/or pressurizing the fluid (2);
• and
• a connecting element (9) for fluidically connecting the cartridge (3) to the delivery mechanism (5) or a pump thereof, wherein:
• the cartridge (3) comprising a closure (21) with an opening (23D) for receiving the connecting element (9) of the nebulizer (1) for fluidically connecting the cartridge (3) to the nebulizer (1), wherein:
• the closure (21) comprises an integrally formed closure part (23) forming sealings (S1, S7) with an outer container (20) of the cartridge (3) by direct abutment against the outer container (20) both in the axial direction and the radial direction of the cartridge (3),
• the cartridge (3) comprises a securing element (30) securing the closure (21) to the container (20) in an axial direction.
