Abstract

A nebulizer includes an insertable container and a securing mechanism for holding the container in the nebulizer such that the container can move back and forth but cannot be separated. The securing mechanism is formed by a metal unitary part. The securing mechanism forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing mechanism forms a cage which encompasses the container.

Claims

1. Nebulizer (1) for a fluid (2) comprising an insertable container (3) containing the fluid (2), wherein the nebulizer (1) comprises a housing for receiving the container (3), wherein the container (3) is moveable back and forth within the housing during conveying of the fluid (2), pressure generation and/or nebulization,

characterized in

that the housing comprises a housing part (18) and a cage as a securing means (35) for holding the container (3) such that the container (3) is moveable back and forth but is inseparable from the housing part (18) and

wherein the cage forms a transportation lock (29) for holding the container (3) unmovable in the housing part in a delivery state of the nebulizer (1), wherein the transportation lock (29) is openable so that the container (3) is moveable within the housing back and forth in the activated state of the nebulizer (1).

2. Nebulizer according to claim 1, characterized in that the cage encompasses an end or bottom portion of the container (3).

3. Nebulizer according to claim 1, characterized in that the securing means (35) comprises holding and/or locking elements (36, 37), preferably wherein the holding and/or locking elements (36, 37) are like fingers, arms or claws and/or extend at least axially or in the direction of the movement of the container (3) and/or can be flexed radially.

4. Nebulizer according to claim 7, characterized in that locking elements (37) securing the container (3) in a delivery state are actuatable or flexible preferably outwardly by the housing or any other component of the nebulizer (1).

5. Nebulizer according to claim 1, characterized in that cage comprises an opening means for opening a venting hole (34) of the container (3).

6. Nebulizer according to claim 1, characterized in that the transportation lock (29) is opened automatically when completely closing the housing.

7. Nebulizer according to claim 1, characterized in that the housing part (18) can be replaced together with the container (3), wherein the container (3) is inseparable from the housing part (18).

8. Nebulizer according to claim 1, characterized in that the securing means (35) is located in the housing part (18).

9. Nebulizer according to claim 1, characterized in that the container (3) is inseparable from the housing part (18) due to a structure, such as a corrugation (45) or any other form of the container (3).

10. Nebulizer according to claim 1, characterized in that the nebulizer (1) is constructed as an inhaler, particularly for medical aerosol treatment.

11. Nebulizer according to claim 1, characterized in that cage comprises or consists of a metal stamping part.

12. Nebulizer according to claim 1, characterized in that the cage consists of a single, unitary part.

13. Housing part for a nebulizer (1), wherein

the housing part (18) comprises a container (3) containing a fluid (2), and

a cage as a securing means (35) for holding the container (3) inseparable from the housing part (18) and

wherein the cage forms a transportation lock (29) for holding the container (3) unmovable in the housing part in a delivery state of housing part (18), wherein the transportation lock (29) is openable so that the container (3) is moveable within the housing part (18) back and forth when the housing part (18) has been pushed completely on the nebulizer (1).

14. The housing part according to claim 13, characterized in that cage comprises or consists of a metal stamping part.

15. The housing part according to claim 13, characterized in that cage is produced from sheet material by cutting and bending.

16. The housing part according to claim 13, characterized in that the cage consists of a single, unitary part.

17. The housing part according to claim 13, characterized in that the cage encompasses an end or bottom portion of the container (3).

18. The housing part according to claim 13, characterized in that the container (3) is inseparable from the housing part (18) due to a structure, such as a corrugation (45) or any other form of the container (3).

19. The housing part according to claim 13, characterized in that the securing means (35) comprises holding and/or locking elements (36, 37), wherein the holding and/or locking elements (36, 37) are like fingers, arms or claws.

20. The housing part according to claim 19, characterized in that the holding and/or locking elements (36, 37) extend at least axially or in the direction of the movement of the container (3).

21. The housing part according to claim 13, characterized in that the securing means (35) comprises holding and/or locking elements (36, 37), wherein the holding and/or locking elements (36, 37) can be flexed radially.

22. The housing part according to claim 19, characterized in that locking elements (37) securing the container (3) in a delivery state are actuatable or flexible preferably outwardly by the housing or any other component of the nebulizer (1).

23. The housing part according to claim 13, characterized in that cage comprises an opening means for opening a venting hole (34) of the container (3).
